Does Pederson Difficulty Index Accurately Predict the Difficulty of Mandibular Third Molar Extraction?

Abstract Context: To determine the relationship between the Pederson difficulty index and the modified Parant scale and to assess the effectiveness of the Pederson difficulty index in predicting the difficulty of mandibular third molar extractions. Settings and Design: This cross-sectional study recruited participants with indications for third molar extractions. Pederson’s difficulty index was used to evaluate the anticipated difficulty of preoperative mandibular third molar extraction. Surgical extraction of impacted third molars was done under local anesthesia and patients were then assessed postoperatively with the Modified Parant Scale. Methods: In this study, 85 participants indicated for surgical extraction of mandibular third molars under local anesthesia were enrolled between February 2018 and July 2018. The relationship between Pederson’s difficulty index modified Parant scale and duration of extraction was evaluated. Statistical Analysis Used: Sociodemographic variables of study participants were summarized with descriptive statistics. Student’s T-test was utilized for mean differences between groups and correlations were computed between Pederson and modified Parant scale. Results: This study comprised 85 participants with a mean age of 25.8 years ± 4.6, showing no significant difference across genders (P = 0.87). Pederson difficulty index demonstrated a sensitivity of 46.4% and a specificity of 89.5% and a moderate correlation (0.35, P < 0.001) was observed between Pederson difficulty index and surgery duration, ditto, between Pederson and modified Parant scores (0.36, P < 0.001). Conclusion: In conclusion, our study underscores the importance of pre-operative assessment for mandibular third molar extraction, highlighting the Pederson Difficulty Index’s moderate predictive value but emphasizing concerns about its sensitivity.

A prospective randomized study on the efficacy of real-time dynamic navigation in deep horizontal mandibular third molar extractions

PurposeThis study aimed to evaluate the clinical efficacy of applying real-time dynamic navigation (RDN) in the extraction of deep horizontal mandibular impacted third molars, hypothesizing that RDN reduces surgical time and minimizes the risk of injury to adjacent anatomical structures.MethodsA prospective study was conducted on 160 patients aged between 18 and 37 years with deep horizontal impaction of the mandibular third molar. The participants were randomly assigned to either the experimental group (receiving RDN-assisted extractions) or the control group (undergoing traditional extraction methods). Preoperative planning utilized cone beam computed tomography (CBCT) and Mimics software for the accurate localization and segmentation of impacted teeth. Parametric data were analysed via an independent t test for intergroup comparisons, and significance was set to p < 0.05.ResultsIn the experimental group, an average of 11 ± 1 min was required for preoperative planning via RDN, which was not required in the control group. The setup of the navigation system took an average of 4 ± 1 min in the experimental group and 0 min in the control group. The experimental group demonstrated a significantly shorter average surgical time (22 ± 3 min) than did the control group (36 ± 3 min). The differences in the preoperative design time, surgical time, and complication rates between the two groups were statistically significant (p = 0.005). Additionally, the RDN group reported no complications related to adjacent tooth damage or nerve injury.ConclusionThe precision, safety, real-time guidance of RDN supports its use in complicated dental extractions, which would introduce a new era of oral and maxillofacial surgery.Graphical

A 3D-Planned Inward Fragmentation Technique for the Removal of Impacted Mandibular Third Molars: A Case Series.

Background/Objectives: The extraction of impacted mandibular third molars (M3Ms) carries significant risks, especially regarding the inferior alveolar nerve (IAN). This study aimed to evaluate the effectiveness of a 3D-planned inward fragmentation technique (3Dp-IFT) to improve surgical outcomes, reduce complications, and preserve bone structure in cases involving complex M3M impactions. Methods: Twenty-three patients aged between 18 and 36 years requiring M3M removal were included. Preoperative planning involved the use of cone-beam computed tomography (CBCT) for precise localization of the furcation area, followed by the creation of a 3D navigation template using PlastyCAD software version 1.7. The surgical procedure was performed under local anesthesia, with meticulous endoscopic assistance to ensure accurate access and minimize trauma. Postoperative outcomes, such as bone loss, pain, swelling, and mouth opening range, were carefully measured. The data were systematically organized and analyzed descriptively using Microsoft Excel. Results: No disturbances to the IAN or lingual nerve were observed. The mean buccal bone loss was 2.2 mm, with a standard deviation of 1.2 mm. Postoperative pain and swelling were generally low, with significant reductions within the first week. The use of the 3D navigation template significantly improved surgical access, enhancing safety and minimizing complications. Conclusions: The 3Dp-IFT technique represents a significant advancement in the minimally invasive removal of M3M by allowing precise access to critical anatomical areas while minimizing bone loss and postoperative complications. This approach is particularly beneficial for complex cases involving M3M near the IAN, thereby improving surgical safety and patient outcomes.

Effect of Hyaluronic Acid on Socket Healing After Lower Impacted Third Molar Tooth Extraction in 40 Dental Patients.

BACKGROUND Surgical extraction of impacted mandibular third molars is the most commonly performed procedure in oral surgery; its associated complications include sensory nerve damage, swelling, and trismus. This study aimed to evaluate the effects of hyaluronic acid (HA) on healing of the socket following extraction of the lower impacted third molar tooth in 40 dental patients. MATERIAL AND METHODS This prospective, double-blind, randomized, controlled study was carried out on 40 adult healthy patients indicated for surgical removal of bilateral impacted mandibular third molars with equal surgical difficulty (moderate surgical difficulty according to the Koerner index. Patients with right mandibular third molars were included into the study (HA) group and those with left mandibular third molars were included into the control group. Surgical removal of impacted teeth was performed at different times for each patient for proper measurement of postoperative clinical variables, including pain, swelling, and mouth opening. RESULTS Postoperative pain evaluation results using the visual analog scale (VAS) showed reduced pain levels at all observation periods. Postoperative swelling peaked in intensity within 12-48 hours, resolving between the 5th and 7th days, and there was no significant difference in pre- and postoperative measurements of interincisal opening between both groups (P>0.05). CONCLUSIONS We found that intra-socket application of hyaluronic acid after surgical extraction of impacted mandibular third molars promoted normal wound healing, and there was a clinical benefit of reduced postoperative pain and swelling.

Prophylactic third molar removal: are oral surgeons and orthodontists aligned in preventive approaches?

BackgroundThere is a general consensus among dental professionals regarding the extraction of impacted third molars in the presence of clinical symptoms. However, there is less agreement on the management of asymptomatic third molars. The objective of this study is to compare the perspectives of oral surgeons and orthodontists regarding the indications for the extraction of asymptomatic third molars. It is possible that healthcare professionals from different specialties may approach the extraction of these teeth in different ways.MethodsIn this cross-sectional study, a web-based questionnaire has been employed to collect data by inquiring about the reasons why participants prefer the extraction of asymptomatic third molars. Descriptive statistics were employed to evaluate the data obtained. The level of significance was set at P < 0.05.ResultsProphylactic extraction of partially impacted molars was more favored among the participants (P < 0.05). The orthodontists preferred prophylactic extraction due to the risk of late anterior dental crowding (LADC); however, the oral surgeons preferred pre-pregnancy extractions (P < 0.05). The extraction decision for partial impaction was higher in females when the risk of distal caries was considered. For fully impacted ones, it was higher in males when the risk of caries and pericoronitis were considered (P < 0.05).ConclusionsOrthodontists preferred extraction because of the risk of LADC and caries, while oral surgeons focused on preventing pericoronitis, pathology, focal infection, and symptoms during pregnancy. This divergence between the participants may inform the guidelines for prophylactic management of third molars. These findings may be pertinent in gender medicine.Clinical relevanceThis study has been enlightening for departments to consult each other before the extraction of a patient’s asymptomatic third molar.

Edema and Trismus Assessment After Applying Kinesiotape With the Web Strip Technique Compared With Cryotherapy: A Randomized Clinical Trial.

Extraction of impacted third molars is one of the most common oral surgeries performed in the dental clinic, which is often accompanied by many complications such as edema and trismus. Many methods have been used to alleviate these complications, such as drugs or physical therapy. Kinesiotape (KT) has recently spread as a popular physical method for eliminating complications after surgical extraction of lower third molars after its long-term use in sports medicine and injuries of the musculoskeletal system. The current study aimed to study the effect of using KT (Kinesio® Holding Corporation, Albuquerque, NM, USA) on both edema and trismus after impacted third molar extraction. This study was designed as a randomized controlled clinical trial using the split-mouth technique and included 25 patients with radiographically symmetrical lower third molars from patients. All surgical extractions were performed by a single surgeon under sterile conditions according to the standard surgical protocol after that one group applied KT and the other group applied cryotherapy. Edema and trismus were measured in the first five days. Data was collected and analyzed by SPSS software (IBM Corp., Armonk, NY, USA). The mean change in the total linear facial measurements in the experimental group (Kinesio Group) was 12.32 mm three days after surgery, and then this value decreased to 6.80 mm, while the average increase in the control group (Cryo Group) was 17.00 mm after three days, then the value decreased to 9.68 mm five days after surgery. Regarding the changes in the amount of maximum mouth opening after surgery, the results were similar between the Kinesio Group and the Cryo Group, as there were no significant differences between the two groups (P<0.05). This study concluded that KT was superior to cryotherapy when studying edema. The current study also concluded that the mouth opening was similar between the two study groups.

Prevalence of surgical site infections following extraction of impacted mandibular third molars: A systematic review and meta-analysis

Our research aims to assess the prevalence of surgical site infections (SSI) following impacted mandibular third molar extractions. Two independent reviewers conducted a comprehensive systematic literature search across Medline, Scopus and Cochrane Central databases. The pooled prevalence, accompanied by 95% confidence intervals (CI), was calculated. Quality assessments, outlier and influential analyses were performed. Our meta-analysis included seventeen eligible studies, encompassing a total of 37,585 impacted mandibular third molar extractions. The overall prevalence of SSI following impacted mandibular third molar extractions was estimated at 1.7% (95% CI 1%-2.6%), indicating considerable heterogeneity among the studies. No study was identified as critically influential. This study highlights the imperative for future well-constructed prospective and retrospective investigations to deepen our understanding of the etiological nuances and refine management approaches for this prevalent postoperative complication.

Effect of residual dental follicle after removal of impacted mandibular third molar on the periodontal health of adjacent second molar

Objective: To investigate whether residual dental follicles in the alveolar socket after extraction of impacted mandibular third molars affect the periodontal health of adjacent mandibular second molars, in order to provide clinical reference for the management of residual dental follicles after third molar extraction. Methods: A total of 82 patients who underwent bilateral impacted mandibular third molar extraction at the Department of Oral Surgery, School and Hospital of Stomatology Wuhan University, from November 1, 2020, to November 30, 2022, were included in the study. Using a self-controlled method, each patient's bilateral mandibular third molars were randomly divided into two groups: Group A underwent third molar extraction with thorough removal of residual dental follicle tissue, while Group B underwent third molar extraction without any treatment of the remaining dental follicle tissue. Operation time and adverse reactions were recorded. Clinical and radiographic examinations were performed at 6-month follow-up to evaluate the periodontal parameters and alveolar bone height of the bilateral mandibular second molars, and differences between the two groups were compared. Results: All patients had successful bilateral mandibular third molar extractions, and no serious complications occurred intraoperatively or postoperatively. There were no statistically significant differences in surgical time, postoperative pain, or facial swelling between the two groups (P>0.05). At the 6-month follow-up, the probing depth on the distal aspect of the mandibular second molars in Group A [2.67 (2.00, 3.67) mm] was significantly less than that in Group B [4.00 (3.00, 5.00) mm] (Z=-6.55, P<0.001). The clinical attachment loss on the distal aspect of the mandibular second molars in Group A [1.00 (0.00, 3.00) mm] was less than that in Group B [3.00 (2.00, 5.00) mm] (Z=-5.99, P<0.001). The distance from the alveolar crest to the cementoenamel junction on the distal aspect of the mandibular second molars in Group A [(1.86±1.34) mm] was less than that in Group B [(3.04±1.89) mm] (t=6.87,P<0.001). In patients aged≥20 years, the probability of recovery of alveolar bone height to normal level on the distal aspect of the mandibular second molars in Group A [42.3% (11/26)] was significantly higher than that in Group B [0 (0/26)] (P<0.01), while there was no statistically significant difference between Group A [63.3% (19/30)] and Group B [46.7% (14/20)] in patients aged<20 years (P>0.05). Conclusions: Residual dental follicles in the alveolar socket after extraction of impacted mandibular third molars adversely affect the periodontal health of adjacent teeth. Thorough removal of residual dental follicles during impacted mandibular third molar extraction is beneficial for the postoperative recovery of alveolar bone height of the distal aspect of the mandibular second molars, especially in patients aged≥20 years.

A comparative study of a two-stage surgical approach combining coronectomy with microimplant anchorage traction for extraction of impacted mandibular third molars with different traction angles

Objective: To establish a two-stage surgical procedure of impacted mandibular third molars (IMTMs) extractions assisted by coronectomy and microimplant anchorage traction and to investigate the influencing factors of root movement and the effects of different traction angles on the clinical outcomes. Methods: Fifty-three IMTM in contact with inferior alveolar nerve (IAN) that underwent tooth extraction in the Peking University School of Stomatology from January 2022 to June 2023 were included, with coronectomy and microimplant anchorage implantation in the first stage of the surgery, root traction was achieved with orthodontic elastic and microimplant anchorages by about 600 g of force, when the IMTM root was detached from IAN, a second surgery was performed to extract the residual root. The basic information of patients and M3M, data on the microimplant anchorage implantation and traction, imaging measurements, and complications were recorded and analyzed. Results: The movement distance of the residual roots was (1.80±0.92) mm, and the duration of traction was (32.9±7.9) d. Multiple linear regression analysis showed that the residual root movement distance was significantly correlated with age, gender, number of roots, traction angle, and depth of the distal bone defect of the second molar (P<0.05). The smaller the traction angle, the more significant the movement of the residual roots (P=0.044). In one case (1.9%, 1/53), the patient experienced abnormal sensation in the lower lip 16 days after traction. Conclusions: The two-stage surgical method of combined coronectomy with rapid traction technique to extract the IMTM allows for rapid movement of the residual root and reduces the risk of IAN injury. The efficiency of root movement can be accelerated by appropriately reducing the traction angle during surgery. The traction effect can be predicted based on indicators such as age, gender, number of roots and depth of distal bone defects of second molar.

Comparison of Piezosurgery Devices and the Use of Rotatory Devices for the Extraction of Impacted Mandibular Third Molars

ABSTRACT The present study aimed to examine the extraction of impacted mandibular third molars by using rotatory and piezosurgery equipment. Twenty-five patients of both genders who required surgery to remove their third molars were split into two groups (control group and research group). In the surgical extraction of the impacted mandibular third molar, in the study group, a piezotome was used to remove the bone, while in the control group, a bur was used. Patients’ acceptance of bone cutting, the length of the operation, discomfort and bleeding during the procedure, postoperative pain, swelling, trismus, and wound healing were evaluated. A statistically insignificant difference was observed for age and difficulty index. The intraoperative bleeding was similar in both groups. Both the groups tolerated the bone cutting well, with slightly better values for the piezo group. Based on Pederson’s difficulty index, the scores of difficulty of extraction of the impacted tooth were measured between the groups. The slight difficulty was observed in 9 (36%) each in the study group and control group. The moderate difficulty in 14 (56%) of control group and 15 (60%) of study group. Severe difficulty was found among 2 (8%) in the control group and 1 (4%) in the study group. The difference was not significant (P &gt; 0.05). Intraoral bleeding was moderately seen in 25 in both groups. Among the study and control groups respectively no intraoperative pain was seen in 14 and 16, mild intraoperative pain in 11 and 7, and moderate intraoperative pain in 0 and 2. Among group I and II acceptance to bone cutting was comfortably seen in 24 and 23, bearable in 1 and 2 respectively. The difference was not significant (P &gt; 0.05). Piezosurgery and bur were comparable in evaluating patient acceptance, intraoperative duration, intraoperative bleeding and pain, postoperative pain, edema, trismus, and wound healing.

Comparison of perineural and systemic dexamethasone use in impacted third molar surgeries in terms of anesthesia duration and postoperative complaints: a controlled, randomized observational study

BackgroundSurgical extraction of impacted third molars (ITM) often leads to postoperative discomfort including pain, swelling, and limited function. Steroids like dexamethasone (DXN) are commonly used in oral surgery to manage pain and inflammation. Various administration routes for DXN exist, including intravenous (IV), perineural (PN), and oral applications, each with its advantages. Previous studies have shown that adding DXN to local anesthetics can prolong anesthesia duration and reduce postoperative sequelae. However, comparative studies on IV and PN applications with inferior alveolar nerve block (IANB) of DXN in ITM surgeries are limited.MethodsThis controlled, randomized observational study involved patients undergoing Class II position B ITM extraction. Patients were divided into three groups. IANB (1.8 ml of articaine hydrochloride + 1 ml of saline) was performed 1 h after IV-DXN (4 mg/ml DXN) was administered to the IV group. DXN along with IANB (1.8 ml of articaine hydrochloride + 1 ml of 4 mg/ml DXN) was applied to the PN group. Only IANB (1.8 ml of articaine hydrochloride + 1 ml of saline) was applied to the control group. Anesthesia duration was assessed as primary outcomes. Anesthesia duration was evaluated using a vitalometer from the molars. Secondary outcomes included postoperative pain and edema measured on the 1st, 3rd, and 7th days after surgery. Pain was evaluated postoperatively by using a visual analog scale. A p-value < 0.05 was considered statistically significant.ResultsThe study included 45 patients with similar demographic characteristics across groups. IV application significantly prolonged anesthesia duration compared to the control group. (p = 0.049) Both IV and PN administration of DXN reduced postoperative edema at 3rd (p = 0.048) and 7th day (p = 0.01). Post-procedure pain reduction was significant in the IV group (p = 0.011). On the other hand, it was observed that the pain did not decrease in the PN group at 3rd and 7th days compared to the control and IV groups.ConclusionsPN and IV DXN administration prolonged anesthesia duration and reduced postoperative edema in ITM surgeries. However, PN DXN administration was associated with increased postoperative pain compared to IV DXN and control groups. Further studies comparing different doses and administration routes of DXN are needed to determine optimal strategies for managing postoperative discomfort in ITM surgeries.Trial registrationThis study was conducted at Ahmet Keleşoğlu Faculty of Dentistry with the permission of Karamanoğlu Mehmetbey University Faculty of Medicine Ethics Committee (#04-2022/101). Trial registration is also available at clinicaltrail.gov. (NCT06318013, 26/05/2024)

Effect of platelet-rich fibrin on the recovery after third molar surgery: A systematic review and meta-analysis

This meta-analysis aimed to elucidate the effects of platelet-rich fibrin (PRF) on the recovery of alveolar bone after surgical removal of the mandibular third molars.PubMed, Cochrane Library, Web of Science, and Embase databases were searched from the inception to February 2023 for relevant studies on the application of PRF after the extraction of impacted mandibular third molars, with the language limited to English. Literature screening was conducted by two independent researchers. The Cochrane risk-of-bias tool was adopted for quality evaluation, and Stata 15.0 was used for statistical analysis. A total of 33 randomized controlled trials were included in the present study. Following surgical removal of the mandibular third molars, 1139 tooth sockets were filled with PRF, while 1138 sockets were sutured after conventional saline irrigation. The meta-analyses showed that PRF can relieve pain [(RR 0.454; 95% CI 0.23, 0.891); (SMD −0.74; 95% CI −0.97, 0.52)], improve swelling (SMD −1.48; 95% CI −1.90, −1.06), alleviate trismus (SMD −0.35; 95% CI −0.51, −0.19), reduce dry socket (SMD −0.18; 95% CI −030, −0.05), and promote bone tissue healing (SMD 2.34; 95% CI 0.18, 4.51). The current study confirms that PRF can reduce some postoperative complications. Local application of PRF after lower third molar extraction is a viable method for relieving pain and swelling, reducing the incidence of dry socket and trismus, and increasing bone density. However, whether it can promote soft tissue healing remains unclear. For patients undergoing complicated surgical extraction, local application of PRF into the sockets might be a good option.

Effect of impacted mandibular third molar extraction on periodontal microbiota and clinical parameters of adjacent teeth: A randomized clinical trial

It is urgently necessary to clarify the effect of extraction of impacted mandibular third molar (IMTM) on the periodontal tissue of adjacent second molars (ASMs). In this study, the ASM periodontal condition and pathogenic microbes were assessed before IMTM extraction and at 1, 4, 8 and 12 weeks postoperatively. Based on the inclusion and exclusion criteria, our study revealed that IMTM extractions adversely affected distal － periodontal probing depth (dPPD), attachment loss (dAL), plaque index (dPLI) and bleeding on probing (dBOP) within 8 weeks, but these indices gradually normalize after 12 weeks. The subgingival pathogens near the ASMs distal surface, Porphyromonas and Pseudomonas, were significantly increased postoperatively. Moreover, relevance of ASMs clinical indices and subgingival microbes after IMTM extractions was found. In contrast to the situation in chronic periodontitis, the effects of IMTM extraction on dPPD, dAL, dPLI and dBOP of ASMs were mainly correlated with Pseudomonas. Additionally, while the IMTM extractions have adverse distal periodontal indices of ASMs within 8 weeks and increase subgingival pathogens, the modified triangular flap (MTF) had fewer distal periodontal indices and less Pseudomonas. Compared to the traditional envelope flap and triangular flap, the MTF benefits the periodontal health, which could be considered as the priority option for IMTM extractions.

Digital technology-assisted extraction of impacted maxillary third molar located between the furcation of maxillary second molar by root dislocation: a case report.

Most of the maxillary impacted third molars are located in the maxillary tuberosity, where the vision and operation space are limited. This paper reports a case of surgical extraction of the left maxillary horizontal superhigh impacted third molar, which is located between the roots of the adjacent teeth and is closely related to the maxillary sinus. The digital simulation technology was used to reconstruct a three-dimensional visual image of the patient's maxilla, related teeth, and other adjacent anatomical structures to assist in finding the optimal surgical method accurately. Root dislocation before the crown not only protects the roots of the adjacent tooth, but also reduces the risk of maxillary sinus lining damage or perforation during operative procedures, improves the efficiency of the operation, and reduces surgical trauma, which conforms to the concept of minimally invasive surgery and provides a new idea and experience for the clinical extraction of such maxillary impacted third molars.

UNRAVELING THE OUTCOMES: A RETROSPECTIVE ANALYSIS OF ABERRANTLY POSITIONED IMPACTED THIRD MOLAR EXTRACTIONS

In the realm of dentistry, the extraction of third molars occupying abnormal positions poses a formidable challenge. These enigmatic teeth, deviating from their anticipated anatomical location, demand meticulous evaluation and specialized approaches to ensure their successful removal. Intriguingly, the evaluation of such cases has remained unexplored in the context of Kazakhstan until now. Aim: The objective of this study is to examine the occurrence of mandibular third molar impaction and its correlation with factors such as impaction type, impaction side, age, and gender among patients. Methods: A retrospective review was conducted on the medical records of 2351 patients who underwent surgical extraction of impacted mandibular third molars. Results: The findings revealed a remarkable prevalence of mesioangular impaction (56.15%) in the lower third molars. The highest number of patients were observed in the age group of 18–30 years (25.05%), and a majority of cases involved the left side (75.75%). A notable female predominance (66.35%) was also observed. The most frequent indication for surgical removal was recurrent pericoronitis (24.25%). Conclusion: This pioneering study in Kazakhstan provides insights into extraction success for impacted third molars. It reveals a remarkable prevalence of mesioangular impaction in the lower molars, predominantly on the left side with a notable female predominance. Recurrent pericoronitis is the primary reason for surgical removal. Early removal of symptomatic impacted molars prevents future complications, but careful patient selection is crucial. Further research is needed to understand these findings in the Kazakhstani population.

Computer-Guided Bone Lid Technique for Surgical Extraction of Deeply Impacted Mandibular Third Molars: A Technical Report

The extraction of mandibular impacted third molars is one of the most common procedures in oral surgery. One of the extraction methods consists of the preparation of a buccal bone lid to obtain access and remove the tooth. This technique aims to reduce bone loss, promote bone healing distal to the second molar, and increase the accessibility to the impacted tooth, particularly in cases of concomitant pathologies or proximity to the mandibular canal. The procedure benefits from the application of 3D printing technologies to produce cutting guides that, combined with piezosurgery, allow deeply impacted third molar extractions with excellent preoperative planning and extreme localisation precision, as well as predictable repositioning and fixation of the bone lid. The objective of this article is to present two clinical cases of the application of the bone lid technique to extract deeply impacted third molars using 3D printed guides with different designs and piezosurgery.

Correlation of Blood Pressure, Heart Rate and Pain with Anxiety, and Importance of its Prevention in Surgery of Impacted Third Molars Under Local Anesthesia

Aim: To examine whether there is a correlation between blood pressure, heart rate, and pain with the level of preoperative and postoperative anxiety in surgery of impacted third molars under local anesthesia. Subjects and Methods: In the study, which included adult patients of both sexes with an indication for surgical extraction of impacted third molars, research parameters were measured as follows: 1st measurement (day of examination) - blood pressure, heart rate, preoperative anxiety with Spielberger’s State-Trait Anxiety Inventory (STAI); 2nd measurement (immediately before the intervention) - blood pressure, heart rate, preoperative anxiety with STAI; 3rd measurement (day after intervention) - blood pressure, heart rate, postoperative anxiety with STAI, postoperative pain with visual analog scale. Results: The values of preoperative and postoperative anxiety and the measured parameters of blood pressure, heart rate, and postoperative pain were statistically significantly positively correlated with each other during all measurements. Conclusion: In order to increase the satisfaction of both the patient and the ordinarius, and to prevent possible complications in this type of oral surgical intervention, it would be useful to consider adequate therapy in order to prevent the development of anxiety, considering the confirmed correlation with the measured parameters.

Two-stage extraction by partial grinding of impacted mandibular third molar in close proximity to the inferior alveolar nerve.

Extraction of impacted third molars often leads to severe complications caused by damage to the inferior alveolar nerve (IAN). To proposes a method for the partial grinding of an impacted mandibular third molar (IMM3) near the IAN to prevent IAN injury during IMM3 extraction. Between January 1996 and March 2022, 25 patients with IMM3 roots near the IAN were enrolled. The first stage of the operation consisted of grinding a major part of the IMM3 crown with a high-speed turbine dental drill to achieve sufficient space between the mandibular second molar and IMM3. After 6 months, when the root tips were observed to be away from the IAN on X-ray examination, the remaining part of the IMM3 was completely removed. All IMM3s were extracted easily without symptoms of IAN injury after extraction. Partial IMM3 grinding may be a good alternative treatment option to avoid IAN injury in high-risk cases.

EFFICACY OF SUBLINGUAL VERSUS ORAL PIROXICAM IN MANAGEMENT OF POST-SURGICAL PAIN, SWELLING AND TRISMUS AFTER LOWER 3RD MOLAR SURGERY- A RANDOMIZED CONTROL CLINICAL TRIAL

Background of the study: Third molar surgical removal is a common procedure in oral and maxillofacial surgery, causing moderate to severe pain, swelling, and trismus. Postoperative pain control improves patient recovery and oral function, with commonly used analgesics including Ibuprofen, Aceclofenac, Ketorolac, Tramadol, Paracetamol, Nalbuphine, Nimusulide, and Buprenorphine. Aim and Objective: The study compares oral and sub-lingual Piroxicam for managing post-surgical pain after extraction of impacted third molars, focusing on analgesia onset, pain intensity, swelling, and trismus degree. Materials and method: A randomized control trial was conducted on 30 patients who underwent surgical removal of mandibular impacted third molars. The patients were divided into two groups: Group I (Study) and Group II (Control). All patients underwent the procedure by a single surgeon. Post-operative medications were prescribed according to the study design, with Piroxicam 20mg administered sub-lingually (Group I) and 20mg orally (Group II). The parameters were assessed and measured for both groups, and the results and statistical analysis were compared. Result: The results revealed that the inter-group difference for the post-operative symptoms evaluated using a t-test for Equality of means by comparing the pre-op, POD 2, POD 7 values was statistically significant. Mean onset time taken and pain perception by Group I (Sub-lingual) in the first dose was 32.3 minutes and for Group II was 51.21 minutes which was established to be significantly (P&lt;0.05) low for the sub-lingual group by statistical analysis. Conclusion: The study found that the sublingual route of administering Piroxicam had a faster onset of action and better analgesia postoperatively compared to the oral route. This is crucial for patients and surgeons to improve compliance and comfort post-operatively after impaction surgery, as potent analgesics are essential for effective pain management.

Comparison of the Efficacy of Corticosteroids With Enzymatic Agents in the Postoperative Sequelae for Lower Third Molar Surgery: A Prospective Study.

Introduction The presence of impacted third molars is a prevalent problem associated with varying degrees of difficulty in extraction and potential consequences, including pain, swelling, and trismus. According to studies, enzymatic combinations, such as bromelain, rutoside, trypsin, and serratiopeptidase, are known to have a very promising role in reducing inflammation and promoting wound healing. This study compared natural enzymatic agents with corticosteroids for postoperative pain, swelling, and trismus in the impacted lower third molar surgery. Objectives The present study aimed to compare the efficacy of prednisolone, a combination of trypsin, chymotrypsin, bromelain, rutoside, and papain, and serratiopeptidase in the postoperative sequelae after surgical extraction of impacted mandibular third molars. The primary objective was to assess the difference in swelling between the three groups. The secondary objectives were to assess the difference inpostoperative painand trismus between the three groups. Materials and methods A total of 150 patients who presented to the department of oral and maxillofacial surgery for surgical removal of an impacted mandibular third molar with a moderately difficult score of 5-7 in the Pederson difficulty index were chosen for a prospective study. Patients were categorized into three groups based on the postoperative drug prescribed. In group 1, prednisolone 10 mg was prescribed;in group 2, a combination of trypsin, chymotrypsin, bromelain, rutoside, and papain was prescribed;and in group 3, serratiopeptidase 15 mg was prescribed. All patients were prescribed a combination drug of aceclofenac 100 mg and paracetamol 325 mg twice daily as a standard analgesic. Swelling, pain, and trismus in each patient were recorded preoperatively and at postoperative day one and day seven.The Friedman test was employed to evaluate the variation in pain levels within the groups over time, while the Kruskal-Wallis test was utilized to investigate the disparity in pain levels between the groups. The difference in swelling and trismus within the groups across the timeline was measured by repeated measures analysis of variance (ANOVA), and the difference in swelling and trismus between the groups was measured by one-way ANOVA.A p-value below 0.05 was deemed to be statistically significant. Results Group 1 showed less swelling, pain, and trismus on both postoperative dayone and day seven compared to group 2 and group 3, which was a statistically significant difference (P < 0.05).
