Effects of a modified surgical protocol on the positional accuracy of dental implants placed using fully guided implant surgery in the partially edentulous posterior ridge with distal extension: a dentiform model study.

The present experiment aimed to evaluate the placement accuracy of fully guided implant surgery using a mucosa-supported surgical guide when the protocol of osteotomy and installation was modified (MP) compared to when the protocol was sequentially and conventionally carried out (CP). For 24 mandibular dentiform models, 12 dentists (6 experts and 6 beginners) performed fully guided implant placements two times at the right first and second molar sites using a mucosa-supported surgical guide, once by the CP (CP group) and at the other time by the MP (MP group). The presurgical and postsurgical stereolithographic images were superimposed, and the deviations between the virtually planned and actually placed implant positions and the procedure time were compared statistically (P < .05). The accuracies were similar in the CP and MP groups. In the CP group, the mean platform and apex deviations at the second molar site for the beginners were +0.75 mm and +1.14 mm, respectively, which were significantly larger than those for the experts (P < .05). In the MP group, only the mean vertical deviation at the second molar site for the beginners (+0.53 mm) was significantly larger than that for the experts (P < .05). The procedure time was significantly longer for the MP group (+94.0 sec) than for the CP group (P < .05). In fully guided implant surgery using a mucosa-supported guide, the MP may improve the placement accuracy when compared to the CP, especially at sites farther from the most-posterior natural tooth.

Success of Nonsurgical Endodontically Treated Posterior Teeth with Complex Restorative/Prosthodontic Treatments: A Retrospective Study.

Endodontic therapy has been regarded as a safe treatment option with highly promising results in preserving natural teeth. Numerous factors may influence the longevity of endodontically treated teeth (ETT), thus altering their success/survival rate. This study aimed to determine the survival and success rates of endodontically treated premolars and molars with different complex restorative/prosthodontic treatments. A total of 190 patients with an ETT were included, who had received final coronal restoration up to 14 days after the temporary one and at least one year prior to the enrollment. The investigator evaluated the quality of endodontic filling, coronal restoration, mobility, and proximal contacts. Data were analyzed with multiple binary logistic regression and the Chi-Square test. The average duration of follow-up was 28.6±11.9 months. Overall, 89.4% (170/190) of the teeth survived. The overall success rate for the investigated teeth was 70.5% (134/190). Success rates of 100% for crown, 95.7% for post and core crown (PCC), and 94.7% for amalgam build-up with post were achieved. However, the success rates were 75%, 52.5%, and 50% for amalgam build-up, composite build-up, and PCC with crown lengthening, respectively. The Chi-square test revealed that there was a significant difference between the different restorations in terms of success (P<0.001). Multiple binary logistic regression models revealed that coronal leakage (P=0.048), obturation void (P=0.037), obturation length (P=0.020), mobility (P=0.002), type of the restoration (P<0.001), and proximal contact (P<0.001) were significant predictors for success. However, apical lucency, root length, marginal caries, tooth type, and post did not appear to be significant indicators of success (P>0.05). ETT with minimal mobility, exhibiting underfilled obturations without visible voids, and having received crown/PCC/amalgam build-up with a post, along with the presence of both proximal contacts, tend to exhibit a significantly high success rate.

Introduction: With the placement of dental implants in edentulous patients, creating and adapting immediate dentures is crucial to allow patients to perform basic physiological functions during the osseointegration period without affecting implant healing. This report presents a case of direct soft lining of immediate complete dentures following implant placement. Case Report: Six dental implants were inserted in the upper jaw, while the patient retained natural teeth in the lower jaw. An immediate complete denture was fabricated and adjusted for the upper jaw. The prosthesis base was prepared and processed to accommodate soft lining material. Adhesive was applied to the prepared base, followed by silicone application for soft fitting onto the prosthesis base, which was then inserted into the patient's mouth. After three minutes, the denture was removed, and soft lining treatment of the immediate complete denture was completed. Conclusion: Direct soft lining facilitated patient adaptation to the immediate prosthesis and supported safer healing and osseointegration until definitive work could be completed. The addition of a soft silicone layer reduced pressure on the residual alveolar ridge and improved adhesion of the immediate prosthesis.

COMPARISON OF THE EFFECTIVENESS OF TREATMENT FOR DENTAL HYPERESTHESIA

Hypersensitivity of hard dental tissues after whitening is one of the most common pathological conditions that create discomfort and have a negative impact on the functional state of the oral cavity. For treatment, 66 patients aged 30–40 years with at least 20–25 natural teeth with a preserved crown and without severe concomitant pathology were selected, with complaints of hyperesthesia of the teeth after professional whitening. Over the course of 6 months, using clinical methods and subjective sensations of patients, the severity of hyperesthesia after treatment with various desensitizers was compared . The high efficiency of Telio CS Desensitizer in the treatment and prevention of hyperesthesia of hard dental tissues was revealed.

Impact of oral health on the quality of life of public servants: an analysis of associated factors.

Oral health encompasses functional and aesthetic aspects that directly impact an individual's daily activities. To analyze the impact of oral health conditions and related factors on the quality of life of public servants. This cross-sectional study was conducted with a sample of 89 public servants, both permanent and outsourced, from a federal public university in northeastern Brazil. Outcome was the impact of oral health on daily activities, determined by the Oral Impacts on Daily Performance indicator, and independent variables were sociodemographic characteristics, normative oral health conditions, access to and use of dental services, self-reported oral morbidity, self-perception of oral health, and absenteeism because of dental reasons. All data were analyzed using descriptive and analytical statistics, using the chi-squared test for heterogeneity and linear trend. The significance level used was set at 5%, with a 95% CI. Participants experienced at least one day of work impaired by dental problems in the six months prior to the survey. Prevalence of dental absenteeism was 7.9%. Variables associated with the impact of oral health on daily activities included gender, toothache, toothache intensity, self-reported oral health, awake bruxism, self-reported need for dentures, number of natural teeth in the upper and lower arches, and signs of temporomandibular dysfunction. Sociodemographic, clinical, and subjective oral health variables influence the impact of oral health on the daily activities of public servants.

Management of a Failed Hybrid Implant Full-arch Prosthesis- A Case Report

Background: Biological and technical hardware complications in implant-retained prostheses are well documented in the literature. The most frequently reported failures are on the immediate or delayed factors after implant placement. Even when the implant has successfully osseointegrated, there is a chance that the prosthesis can fail if the treatment planning and occlusal aspects are not well studied. Management of failed cases is rarely reported. In this case report, the authors present a failed implant prosthesis and how it was managed well with a more permanent solution.&#x0D; Case presentation: A 55-year-old, male retired bank manager, reported with the chief complaint of frequent fracture of the maxillary acrylic hybrid implant prosthesis that was delivered 6 months ago. He wanted a replacement for the fractured upper maxillary acrylic hybrid prosthesis. On clinical evaluation, the upper maxillary implant prosthesis was opposing the natural tooth, an anterior bridge, and two posterior implants in the lower right and left of the first and second molar region. The patient was happy with the lower restorations.&#x0D; Conclusion: The design of the final restoration based on biological, mechanical, technological, and patient factors should be ideally planned during the initial treatment planning stage itself. In case a prosthesis fails the underlying cause should be analyzed and retreatment planning is to be done.&#x0D; Bangladesh Journal of Medical Science Vol. 23 No. 01 January’24 Page : 266-271

Salivary Interleukin-6 as a Non-Invasive Biomarker for Chronic Periodontitis and Tooth Loss in Type 2 Diabetes.

Periodontitis and type 2 diabetes are chronic inflammatory diseases that increase inflammatory Interleukin-6 (IL-6) levels that induce the production of advanced glycation end products (AGEs) causing receptor activator of nuclear factor-kappa B ligand (RANKL) expression on osteoclasts, contributing to further alveolar bone destruction. To assess the role and diagnostic potential of salivary IL-6 (SIL-6) in the detection and evaluation of chronic periodontitis (CP) and tooth loss in type 2 diabetes mellitus (T2DM). This cross-sectional study comprised 240 subjects aged 30-69 years with minimum of 15 natural teeth. Fasting, unstimulated whole saliva was collected, full-mouth intra-oral examination and periodontal evaluation were performed using PCP-UNC 15 probe and glycaemic (HbA1c) levels were analysed by high-performance liquid chromatography (HPLC) method. Subjects were categorised into four groups of 60 participants each: Group 1 (controls); Group 2 (CP); Group 3 (T2DM with CP); Group 4 (T2DM with CP and tooth loss). Salivary IL-6 levels were quantitatively assessed by enzyme-linked immune sorbent assay method. Average SIL-6 levels were significantly elevated in Group 4 (T2DM with CP and tooth loss) (P = 0.001) and in severe periodontitis (P = 0.001). Karl Pearson Correlation found a significant association between average SIL-6 and average periodontal pocket depth (APPD) (r = 0.180), average clinical attachment loss ≥3 mm (ACAL3) (r = 0.289) and severity of periodontitis (r = 0.3228). The receiver operating characteristic (ROC) curve depicted an overall sensitivity of 53.3%, specificity of 68.6% and accuracy of 60% in the detection and assessment of CP in T2DM with tooth loss. IL-6 in saliva is a valuable, non-invasive biomarker in the detection and evaluation of CP in T2DM with tooth loss.

Biological Width around One- and Two-piece Implants: A Systematic Review

The concept of biological width (BW) around dental implants is crucial for the long-term success of implant placement. This systematic review aimed to investigate the differences in BW around one- and two-piece dental implants and to assess the impact of implant design on peri-implant soft tissues. To compare biological width around one-piece and two-piece implant in a population undergone implant treatment. A comprehensive search of MEDLINE (via PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Web of Science, CINAHL, PsycINFO, and Google Scholar was conducted to identify studies that compared the BW around one- and two-piece dental implants. Eligibility criteria included published peer-reviewed studies that provided quantitative measurements of BW and related soft-tissue dimensions. Data extraction and synthesis were performed, and the findings were compared for consistency and relevance to the research question. The review included four studies that met the inclusion criteria. Two studies suggested that two-piece implants might lead to an adaptive change in BW and marginal bone levels over time. One study indicated that one-piece implants could maintain a BW and gingival margin position similar to that of natural teeth, while another found no significant long-term differences in soft-tissue volumetric stability between the one- and two-piece systems. The evidence pointed toward the microgap and implant design as influential factors in determining peri-implant soft-tissue dimensions. We found that implant design, particularly the presence of a microgap, plays a significant role in the establishment and maintenance of BW around dental implants. Two-piece implants may induce a greater adaptation in BW, whereas one-piece implants may better mimic the natural soft-tissue architecture. Long-term volumetric stability of the soft tissues appeared to be comparable between the two systems. These findings can inform clinical decision-making regarding the choice of implant systems for optimal soft-tissue health and integration.

Assessing the Efficacy of Novel Fiber-Reinforced Dual-Cure Luting Resins.

Dual-cure resin-based luting materials are increasingly favored in clinical applications due to their capacity to establish a strong bond with natural tooth structure and restorations. This study aimed to examine certain physical and handling characteristics of newly developed experimental dual-cure luting resins reinforced with short fibers (SFRCs) and compare them with commercially available dual-cure luting resins. Seven dual-cure luting materials were tested (Relyx Ultimate, Duo-Link, eCEMENT, Variolink Esthetic, G-CEM LinkForce, experimental SFRC1, experimental SFRC2). Fourier transform infrared spectroscopy (FTIR) was utilized to determine the degree of monomer conversion (DC%) in the self and light-curing protocol. A rotating disk rheometer measured viscosity at room temperature (22°C) and simulated mouth temperature (35°C). Fracture toughness, flexural strength, and flexural modulus were evaluated using a 3-point bending test. Each luting resin was subjected to the examination of its surface microstructure using scanning electron microscopy (SEM). Analysis of variance (ANOVA) at a significance level of (p = 0.05) was conducted to analyze data. It was revealed that DC% of the tested dual-cure resins was significantly (p< 0.05) affected by the curing mode, the dual-cure SFRC2 having the highest and Relyx having the lowest DC (64%, and 41% respectively). The viscosity of all tested materials decreased with increasing temperature. SFRC2 demonstrated the highest fracture toughness (2.3 MPa m1/2), while Relyx Ultimate, Duo-Link, and eCEMENT exhibited the lowest values (≈ 1 MPa m1/2)(p< 0.05). Both SFRCs and G-CEM link-force exhibited the highest flexural strength values, and SFRCs resulted in the highest flexural modulus values (p<0.05). The experimental fiber-reinforced dual-cure luting resins exhibited superior DC%, fracture toughness, and flexural properties, yet, SFRC2 showed the highest viscosity at elevated temperature. These results highlight the capability of short fiber reinforcement to enhance the mechanical properties of dual-cured resin-based luting materials without compromising handling characteristics. Key words:Dual-cure luting resin; short fibers; degree of conversion; viscosity; fracture toughness; flexural properties.

Association between number of teeth, dental prostheses, and self-reported dysphagia in brazilian old people: a population-based study.

To investigate the association between the number of permanent teeth and the use of removable dental prostheses with self-reported dysphagia occurrence in individuals aged 60 years or older. A population-based cross-sectional study was conducted with 5,432 old individuals who participated in the baseline of the Brazilian Longitudinal Study of Elderly Health (ELSI-Brazil). The outcome "dysphagia" was associated with the number of permanent teeth and the use of removable dental prostheses. Sociodemographic independent variables (age, sex, and race/ethnicity) and clinical history variables (no morbidity, one morbidity, or more than two morbidities) were analyzed using Poisson Regression with robust variance and their respective 95% confidence intervals (CI). The prevalence of self-reported dysphagia in non-institutionalized old individuals was 30%. The group of old individuals with 10 - 19 natural teeth showed a 52% increased risk of self-reported dysphagia complaint (PRadj 1,565 IC95% 1,34;1,826) compared to their counterparts with more teeth. An association was found between a lower number of teeth and removable prostheses with the occurrence of dysphagia.

Alkasite restorative material for endodontically treated teeth: a randomized controlled pilot study.

This study aimed to evaluate the clinical performance of an alkasite restorative material in molars that had undergone root canal treatment. The research was registered in Brazilian Registry of Clinical Trials. The randomized clinical trial involved 33 patients, each with at least 1 mandibular molar requiring restoration after receiving endodontic treatment. Patients were randomly assigned to receive either bulk-fill resin composite (Tetric N Ceram Bulk Fill, Ivoclar Vivadent) or the alkasite restorative material (Cention N, Ivoclar Vivadent). Upon completion of the restorations, 3 calibrated professionals utilized the United States Public Health Service criteria to assess various factors, including retention, secondary caries, marginal adaptation, restoration color, marginal pigmentation, and anatomical form. Evaluations were conducted at intervals of 7 days, 6 months, and 17 months. Additionally, the assessment encompassed the presence of radiolucent lines adjacent to the restoration, material deficiencies or excess, contact points, and caries recurrence. The data underwent analysis using the Friedman and Mann-Whitney tests (α = 0.05). After 17 months, the results revealed that the alkasite restorative material exhibited greater wear of anatomical shape compared to the bulk-fill resin composite (p = 0.0189). Furthermore, the alkasite restorative material significantly differed from the natural tooth color in most cases (p = 0.0000). However, no other criteria displayed significant differences between the materials or over time (p > 0.05). The alkasite restorative material (Cention N) emerges as a viable option for restoring endodontically treated teeth, displaying clinically acceptable alterations after a 17-month evaluation period.

Digital Shade Matching Techniques in Fixed Prosthodontics

When it comes to fixed prosthodontics, making sure that the natural tooth color is accurately replicated is extremely important for achieving results and satisfying patients. However traditional shade matching methods that rely on judgment have often led to variations. The introduction of technologies has completely transformed this field by bringing in precise techniques. One notable advancement is spectrophotometry, which objectively analyzes the color spectrum by measuring how light reflects and transmits across wavelengths. This method has proven to be effective in improving the accuracy of shade matching while minimizing the influence of factors. Additionally, digital photography with lighting conditions has refined color determination by allowing for accurate documentation and communication among dental professionals. By integrating color management systems, consistency across devices can be ensured, which is crucial for shade matching results. The future oriented aspect of artificial intelligence also plays a role in this field as machine learning algorithms have the potential to surpass human capabilities in recognizing subtle variations in color. The clinical implementation of digital shade matching brings about precision, efficiency and communication addressing the limitations of methods and providing a more accurate reproduction of natural tooth color. Despite challenges such as standardizing lighting conditions and replicating nuances in tooth color accurately it is evident that these advancements have positively transformed fixed prosthodontics. Managing digital shade matching involves adopting an approach that includes incorporating technologies implementing robust clinical protocols and providing ongoing education for dental professionals. However, there are still some difficulties continuous progress has made digital shade matching a solution. It provides a systematic method for determining the color in fixed prosthodontics. As dental practices embrace these advancements, the synergy of technology and clinical expertise promises to redefine esthetic dentistry standards.

Evaluation of the Bonding Shear Strength between Enamel and Dentin Feldspathic Porcelain and Two Different Monolithic Zirconia with Low and High Translucency.

The utilization of ceramics in the field of dentistry has seen a significant rise owing to their esthetic appeal and excellent functional properties. The use of ceramics in the field of dentistry has witnessed a notable surge, driven by their appealing esthetics and exceptional functional attributes. Zirconia, distinguished by its exceptional mechanical strength, plays a pivotal role in the fabrication of posterior crowns and bridges. Among zirconia variants, monolithic zirconia stands out, where the entire restoration is crafted from zirconia material. In parallel, feldspathic porcelain, chosen for its remarkable resemblance to natural tooth enamel, represents another significant ceramic type. This study aims to evaluate the shear bond strength (SBS) between two types of monolithic zirconia with two types of feldspathic porcelain. Forty-four monolithic zirconia veneered discs with feldspathic porcelain were subjected to SBS testing. The dimensions of the discs were 7 mm in diameter and 5 mm in height (3 mm of zirconia and 2 mm of porcelain). Subsequently, the specimens were subjected to a universal testing machine at a speed of 0.5 mm/min until failure occurred. The type of failure was examined using scanning electron microscopy. One-way analysis of variance (ANOVA), two-way ANOVA, Fisher's test, and multiple Tukey comparisons were used as statistical analyses. The highest SBS was achieved by the high-translucency monolithic zirconia with enamel porcelain group (18.81 ± 3.18 MPa) and the high-translucency monolithic zirconia with dentin porcelain group (17.89 ± 2.75 MPa), followed by the low-translucency monolithic zirconia with dentin porcelain group (15.04 ± 2.24 MPa) and the low-translucency monolithic zirconia with enamel porcelain group (14.33 ± 2.00 MPa), respectively. Additionally, the most common type of failure pattern observed was mixed, followed by adhesive failure. The translucency of the porcelain did not significantly affect SBS, while the type of monolithic zirconia used had a significant impact. Furthermore, there was no discernible relationship between the four groups in terms of the distribution of failure patterns.

The Synergistic Effect of High Intensity Focused Ultrasound on In-vitro Remineralization of Tooth Enamel by Calcium Phosphate Ion Clusters.

Remineralization of dental enamel is an important intervention strategy for the treatment of demineralized lesions. Existing approaches have limitations such as failure to adequately reproduce both the ideal structural and mechanical properties of the native tooth. The ability of ultrasound to control and accelerate the crystallization processes has been widely reported. Therefore, a new approach was explored for in-vitro enamel remineralization involving the synergistic effect of high-intensity focused ultrasound (HIFU) coupled with calcium phosphate ion clusters (CPICs). The demineralized enamel was treated with CPICs, with or without subsequent HIFU exposure for different periods (2.5, 5, and 10 min). The specimens were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), and Raman spectroscopy. The surface hardness and crystallographic properties of the treated specimens were evaluated using Vickers microhardness testing and X-ray diffraction (XRD), respectively. SEM revealed distinct, organized, and well-defined prismatic structures, showing clear evidence of remineralization in the combined CPIC/HIFU treatment groups. AFM further revealed a decrease in the surface roughness values with increasing HIFU exposure time up to 5 min, reflecting the obliteration of interprismatic spaces created during demineralization. The characteristic Raman band at 960 cm-1 associated with the inorganic phase of enamel dominated well in the HIFU-treated specimens. Importantly, microhardness testing further demonstrated that new mineral growth also recovered the mechanical properties of the enamel in the HIFU-exposed groups. Critical to our aspirations for developing this into a clinical process, these results were achieved in only 5 min. HIFU exposure can synergise and significantly accelerate in-vitro enamel remineralization process via calcium phosphate ion clusters. Therefore, this synergistic approach has the potential for use in future clinical interventions.

Prevalence of Tooth Loss due to Periodontitis in Patients Visiting Tertiary Care Hospital

Introduction: Epidemiological studies have been showing that caries is the main reason for tooth loss. But nowadays, it seems to show an increasing trend of tooth loss due to periodontal reasons rather than caries. The retention of natural teeth can improve the quality of life by maintaining the ability to chew and digest food. Thus, directly or indirectly periodontitis leading to tooth loss affects quality of life.&#x0D; Objective: To determine the prevalence of tooth loss in periodontitis patients.&#x0D; Methods: A cross-sectional study was done in Department of Periodontology and Oral Implantology from June 2023 to September 2023 after obtaining ethical clearance from institutional review committee. Study participants were patients diagnosed as periodontitis according to world workshop in periodontics 2017 classification and prevalence of tooth loss was recorded according to the history of mobile tooth. Poor prognosis and hopeless prognosis were counted as to be extracted tooth in the study. Collected data were entered into the excel sheet and further statistical analysis was done using SPSS v.20.&#x0D; Results: Mean of tooth loss due to periodontitis was found to be 3.74±3.285 and tooth to be extracted is 1.94±1.884. &#x0D; Conclusion: As the age increases number of tooth loss increases, likewise current smokers have more amount of tooth loss than that of former and nonsmokers. Likewise, mandibular anterior region was most common for prevalence for tooth loss.

Effect of curing distance for cure depth in composite resin.

The effect of altering the distance between light tip and outer layer of composite (DLR) on the depth of composite cure with a range of low to high light intensity curing lamps and with different types of light unit is of interest. Three LED units (T= Freelight,U = Ultrablue IS, V = Coltolux LED, one PAC unit (S=PAC) and three halogen light-curing units (P = XL2500, Q = HelioluxVL, R = Visiolux) were analyzed. A human molar tooth that was separated mesio-distally to buccal and lingual halves was used to create a natural tooth sample. Data shows that the depth of cure for the composite material decreased as the distance between the repair and the light source increased. There was no appreciable difference in performance between the LEDs and the other kinds of curing lamps as the distance between them grew.

Comparison of Commercially available denture teeth with available natural teeth dimensions among genders

Background: Selecting the artificial teeth is an art, every prosthodontist should learn the art to fulfill the esthetic and functional requirement of the patient. It gives a pleasing, expressive and confident life to the patient. Aim: To compare the dimensions of natural maxillary and mandibular anterior and posterior teeth with the dimensions of three commercially available denture teeth such as Acryrock,Biorock and Ivoclar Vivadent along with gender consideration. Materials and Methods: The length and width of the natural anterior and posterior teeth from dentate casts of 23 males and 77 females were examined by a single examiner using a digital vernier caliper on a straight line and using a flexible ruler . These dimensions were also measured in three denture teeth mold charts: Acryrock, Biorock, Ivoclar vivadent. The dimensions thus obtained are compared between the three systems of artificial teeth and natural teeth for selecting the best system of artificial teeth for complete denture prosthesis. Results: This present study concludes that the width of available natural maxillary anterior teeth matches with the dimensions of all the three commercially available denture teeth such as Ivoclar Vivadent, Acryrock, Biorock. But the mandibular anterior and posterior teeth of maxillary and mandibular dentate cast dimensions were matching only with the Ivoclar vivadent teeth set irrespective of the genders. Conclusion: From this study, the determination of the size of anterior and posterior artificial teeth using the natural teeth dimensions for fabrication of complete denture prosthesis was proved statistically and mathematically.
