Treatment of gingival enlargement caused by orthodontic treatment

The aim of this study was to assess the healing process of gingival enlargement in adolescents with and without fixed orthodontic appliances using conventional scalpel treatments over a 3-month follow-up period. 20 patients with gingival enlargement were divided into two groups. The control group, without fixed orthodontic appliances, received mechanical treatment through conventional scalpel. Test group, comprising patients with fixed orthodontic appliances, was treated using conventional scalpel. Follow-up visits were conducted on days 1 and 90. Clinical periodontal parameters, including plaque index, gingival index, bleeding on probing, probing pocket depth, and gingival overgrowth index, were compared across groups at different time intervals from baseline. All groups exhibited statistically significant reductions in clinical periodontal parameters during the study period (P < 0.05). Test group, treated with conventional scalpel, showed the fastest and most consistent improvements in the healing process compared to baseline. Conventional scalpel therapy proved to be an effective method for treating gingival enlargement, with no reported discomfort or pain during or after the procedure. Given the challenges patients with fixed orthodontic appliances face in maintaining oral hygiene, they should be scheduled for more frequent follow-ups and given thorough home-care instructions.

Acoustic black hole ultrasonic scalpel

Ultrasonic scalpels (USs), as the preferred energy instruments, are facing a growing need to exhibit enhanced performance with the diversification of modern surgical challenges. Hence, we proposed an acoustic black hole ultrasonic scalpel (ABHUS) in longitudinal-bending coupled vibration for efficient surgical cutting. By incorporating an acoustic black hole profile, the local bending wave velocity is reduced and the amplitude is amplified cumulatively, thus creating a high-energy region near the blade tip to enhance the cutting performance of the ABHUS. The precise physical analysis model is established for systematic design of the ABHUS and quick estimation of its frequency characteristics. The vibration simulation and experiments demonstrate that compared with the conventional ultrasonic scalpel (CUS), the output amplitude of the ABHUS significantly increases, particularly a 425% increase in bending vibration displacement. The in-vitro cutting experiment confirms that ABHUS exhibits superior cutting performance. Our design presents vast possibilities and potential for the development of high-performance ultrasonic surgical instruments, serving as an innovative supplement with extraordinary significance for application of acoustic black holes.

Evaluation of patient perception and intraoperative bleeding in labial frenectomy: A comparision of diode laser and conventional scalpel techniques

: High frenal attachments are abnormalities corrected by surgical procedure called frenectomies. The scalpel technique is associated with pain, bleeding and postoperative discomfort. To overcome these shortcomings, in the recent times, diode lasers are gaining popularity due to less bleeding, pain during the procedure, healing outcome, and need for analgesics: To compare the bleeding during the procedure and postoperative pain in patients requiring labial frenectomy using conventional scalpel and diode laser techniques. Twenty patients with high labial frenum attachment requiring frenectomy were included in this study. Patients were randomly divided into Group A: scalpel group and Group B: diode laser group. Pain assessment using VAS, severity of intraoperative bleeding and number of analgesics used were recorded: The analysis showed that VAS score for pain was significantly lower in the laser group as compared to the scalpel group Bleeding was mild in laser group, where as in scalpel group showed moderate or severe bleeding scores Post operative use of analgesics was more in scalpel group than laser group Laser was found to be an effective alternate to scalpel in performing frenectomy procedures, more importantly it showed less bleeding, less pain perception and more patient acceptance during the procedure.

CO2 LASER versus Blade Scalpel Surgery in the Management of Nasopharyngeal Masses in Dogs.

We aimed to compare surgical time, bleeding level, patient pain level, healing period, scar tissue, relapse of the initial process and complications in patients with nasopharyngeal oncological masses undergoing surgery using a scalpel blade versus a CO2 surgical laser. This is a clinical prospective study comprising surgical work in the nasopharynx area. A sample of 12 inpatients dogs (N = 12) of both genders underwent a surgical excision of nasopharyngeal masses with a scalpel blade (GS n = 6) and CO2 surgical laser (GL n = 6). An Aesculigth CO2 surgical laser-Vetscalpel® model with a superpulse mode, 12 W of power, and a multi-focus pen was used. Statistically significant differences were registered for a p-value of < 0.05. Variations were noted between both groups (GS and GL) concerning surgery time (p = 0.038), first meal time (p = 0.013), pain level (p = 0.003), and healing time (p = 0.014), with the GL group presenting lower values. GL exhibited only one relapse case, with the elapsed time being more than double that of the GS group. Surgical and healing times were shorter in the GL group, and pain levels were lower, with the GL group also demonstrating less scar tissue than the GS group, along with a lower relapse rate. Nasopharynx surgical exposure with precision via the soft palate using the CO2 laser has facilitated successful treatment of regional masses without discomfort and complications, compared to conventional blade scalpel procedures.

Topographical and histological analysis of keratinized mucosal grafts removal techniques an ex-vivo study in porcine mandibles

The aim of this study was to assess the surface and tissue quality of keratinized mucosa grafts (KMG) obtained using the conventional scalpel and mucotome techniques. This was an experimental in vitro/ex vivo study involving six porcine hemi-mandibles. Specimens were harvested using both the mucotome and conventional scalpel techniques, with randomization determining the choice of technique for tissue removal. The specimens were prepared following predefined laboratory protocols and subsequently subjected to optical microscopy for evaluating epithelial and connective tissue and scanning electron microscopy for topographical and 3D profilometry analysis. Tissues harvested using the mucotome exhibited a linear base and uniform thickness, along with the presence of submucosa and fibrous connective tissue, all of which are ideal for graft success. Differences in the surface characteristics of specimens obtained through the two techniques were observed during a comparative analysis of images obtained through both microscopy types. KMG obtained using the mucotome technique displayed greater uniformity and reduced undesirable cell presence compared to the scalpel technique, thereby enhancing the likelihood of success in soft tissue graft surgical procedures. This study provides valuable insights to oral healthcare professionals and may contribute to future research aimed at achieving more successful surgeries, shorter postoperative recovery times, reduced discomfort, and an overall more positive patient experience.

The impact of 0.24% hyaluronic acid gel on pain level and periodontal status following labial frenectomy

Aim: The labial frenum is a mucosal fold that connects the upper lip to the alveolar ridge. Frenectomy involves the surgical removal of a mucosal fold. The traditional surgical technique utilizing a scalpel remains popular for performing a frenectomy. The study aims to examine the effectiveness of applying Hyaluronic Acid (HA) Gel after conventional frenectomy. Methods: This research comprised 48 young patients (25 girls and 23 boys) aged 8 to 14. Participants were randomly divided into two groups. Group 1: Conventional Scalpel Surgery and Sterile Saline (SS) (n=24) and Group 2: Conventional Scalpel Surgery+HA (Aftamed, Child Gel 24% HA) (n=24). After measuring the participants’ periodontal parameters, the frenectomy was performed. Postoperative pain levels were evaluated daily for one week utilizing a 10-point Visual Analog Scale. Before frenectomy, Plaque Index (PI), Gingival Index (GI), Pocket Depth (PD), Bleeding On Probing (BOP), Keratinized Gingival Width (KGW), Attached Gingival Thickness (AGT) values were measured and recorded. The periodontal parameters were assessed and analyzed after a 3-month follow-up period. Results: VAS (Visual Analogue Scale) was assessed. The application of Although 0.24% HA gel caused less pain from days 1-3.6, there was no significant difference in pain levels between the HA gel and control groups (p&gt;0.05). Pain levels were equal between groups on day 7. No significant changes in PI, GI, PD, BOP, KGW, or AGT values after three months of follow-up (p&gt;0.05). Conclusions: During the first week after a frenectomy performed with classic scalpel surgery, the application of 0.24% HA gel did not significantly reduce pain levels. It did not result in significant changes in other measured periodontal parameters after three months of follow-up.

Enhancing surgical flexibility: Modeling of a novel curved-waveguide ultrasonic scalpel for intricate procedures

In surgical scenarios such as thoracic procedures where target tissues locate behind sternums, the conventional rigid-long-straight ultrasonic scalpel is hard to operate. To solve the problem, this paper proposes a novel curved-waveguide ultrasonic scalpel (CWUS) with TC4 material. Through mathematical derivations and simulations, the dimension of CWUS is determined. Modal, transient, and fatigue life simulation by COMSOL demonstrate that the proposed CWUS effectively suppresses lateral vibrations in the scalpel body, and can output a comparable amplitude to conventional ultrasonic scalpels with an enough fatigue life. Consequently, the proposed novel CWUS is especially useful for doctors to perform complex operations in thoracic invasive surgery safer and more flexible.

Advantages of the co2 laser use in the rare condition of nasal mucosa squamous cell carcinoma surgery in dogs-a clinical prospective study.

Nasal mucosa tumors are an uncommon process and very dificult to work on with surgery. Radiotherapy associated or not with chemotherapy is the standard method to treat the disease. However, its access it is in the majority of the case not possible, making the surgery the best choice to try to achieve the patient's control. The anatomy of the region makes the complete surgical resection very difficult to achieve using the common and conventional blade scalpel surgery.The study features the advantages of using a CO2 laser to perform nasal mucosa carcinoma surgery in 6 dogs (N = 6). For the work we used an Aesculigth CO2 surgical laser model -Vetscalpel®, with the settings of 12Watts in a Superpulse mode, and a 0.25-0.4mm focus to dissect the nasal mucosa, and a 1.5mm focus for vaporization of the area. All the masses were histopathologically characterized as squamous cells carcinoma. The CO2 surgical laser allow us to work in a bloodless region promoting a more accurate dissection of the nasal mucosa sparing therefore the underlying and adjacent tissues and being less invasive. Also, it was possible to do the vaporization of the entire surgical area interviened. None of the patients presented relapse of clinical signs. Only 2 individuals were alive at the end of the study, presenting a survival rate of 420 and 514days, which is in the same line of literature results of the treatment with radiotherapy combined with chemotherapy wich shows a median of 474-580days. The study demonstrates successful outcomes with CO2 laser surgery in treating nasal mucosa SCC in dogs, with patients experiencing improved survival rates compared to traditional treatment methods. This highlights the efficacy and potential of CO2 laser surgery as a valuable tool in managing aggressive nasal tumors in veterinary oncology.

Management of Abnormal Frenulum and Gingival Enlargement in One Visit

Gingival enlargement or excessive gingival growth, is a common occurrence in gingival disease, characterized by an increase in the size of the gingiva. Inflammatory gingival enlargement or inflammatory gingival enlargement is an inflammatory response to local irritation related to the gingiva. The most frequently performed treatment for gingival enlargement is gingivectomy. A high frenulum makes it easier for the gingival margin to be pulled so that plaque is easily trapped in the sulcus which results in periodontal disease and can be corrected with a frenectomy procedure. A 22-year-old female patient came to RSGM UMY complaining that her upper front gums had become enlarged so she was lacking self-confidence. Intraoral objective examination revealed enlarged gingiva on the interdental papillae of the maxillary anterior teeth (12, 13, and 21) which were rounded, light red in color with the surrounding gingiva, and had a smooth surface. There is a high frenulum with a height of 8 mm. A blanching test was carried out to examine the frenulum and the results were positive (+).Gingivectomy can be performed with a conventional scalpel, electrosurgery, chemosurgery, and laser. Conventional gingivectomy surgery performed with a small scalpel has been considered the most common method due to its ease of use, accuracy, and minimal tissue damage. Frenectomy can also be performed using various methods, such as using a scalpel, electrosurgery, or laser. Gingivectomy and frenectomy surgical procedures are effective in managing enlarged gingiva with a high frenulum

Management of Ankyloglossia Using Conventional Surgical Technique: A Case Series

Periodontal plastic surgery is a more conservative and precise technique practised to create more functional and aesthetic results for the treatment of mucogingival problems. The presence of an aberrant frenum is one of the aetiological factors associated with the persistence of a midline diastema. Inadequate dental plaque removal, poor oral hygiene, bifid tongue, impaired speech, and mucogingival problems like recession and black triangles need more attention. Ankyloglossia, or tongue-tie, is a congenital anomaly with an abnormally short lingual frenulum. The aberrant frenum can be treated with surgical removal of the frenum using either frenectomy or frenotomy procedures. In the present case series, frenectomy was performed using a conventional scalpel technique for the treatment of tongue tie.

Leveraging artificial intelligence for perioperative cancer risk assessment of oral potentially malignant disorders.

Oral potentially malignant disorders (OPMDs) are mucosal conditions with an inherent disposition to develop oral squamous cell carcinoma. Surgical management is the most preferred strategy to prevent malignant transformation in OPMDs, and surgical approaches to treatment include conventional scalpel excision, laser surgery, cryotherapy, and photodynamic therapy. However, in reality, since all patients with OPMDs will not develop oral squamous cell carcinoma in their lifetime, there is a need to stratify patients according to their risk of malignant transformation to streamline surgical intervention for patients with the highest risks. Artificial intelligence (AI) has the potential to integrate disparate factors influencing malignant transformation for robust, precise, and personalized cancer risk stratification of OPMD patients than current methods to determine the need for surgical resection, excision, or re-excision. Therefore, this article overviews existing AI models and tools, presents a clinical implementation pathway, and discusses necessary refinements to aid the clinical application of AI-based platforms for cancer risk stratification of OPMDs in surgical practice.

Effects of an Ultra-Polished Scalpel on Incisional Wounds in a Diabetic Model.

Inflammation after surgical incisions is related to the degree of tissue damage. Healing with low inflammation is desirable, especially in patients with compromised healing potential. This experimental study was conducted to assess the degree of inflammatory reaction and scar formation from incisions made by an ultra-polished scalpel (UPS). Two paravertebral incisions were made with a conventional scalpel (CS) and a UPS in 18 individual rats with diabetes. The fibrotic tissue (scar) area and expression levels of collagen, transforming growth factor, and matrix metalloproteinases were quantified on postoperative days 3, 7, and 30. The scar widths and areas were significantly lower in the UPS group than in the CS group. The scar widths were 64.3 ± 14.7 µm and 86.8 ± 12.1 µm in the UPS and CS groups, respectively ( P = 0.03). The scar areas were 11,398 ± 1595 µm 2 in the UPS group and 17,433 ± 3487 µm 2 in the CS group ( P = 0.014). The UPS group had less inflammation on day 3, less transforming growth factor synthesis on days 3 and 7, lower levels of matrix metalloproteinases, and less collagen synthesis on day 7 than did the CS group. The UPS achieved less local inflammation by reducing the local tissue damage in diabetic rat models, enabling better healing, and resulting in less scar formation. The UPS warrants further clinical study as it may bring beneficial outcomes for patients with impaired healing capability and patients who seek to reduce scarring.

Diathermy versus Scalpel Skin Incision for Open Inguinal Hernia Surgery: An Interventional Study

Introduction: Inguinal hernia is one of the most encountered surgical-related problems worldwide. For years, there has been debate among surgeons about which type of skin incision to use: cutting with electrocautery or the traditional method of a surgical scalpel. Aim: To compare the skin incisions made with electrocautery versus traditional scalpel incisions in terms of incision time, blood loss, postoperative pain, and scar evaluation. Materials and Methods: A hospital-based prospective interventional study was conducted at the Department of General Surgery, Sri Manakula Vinayagar Medical College and Hospital, Puducherry, India, from November 2019 to September 2021. Written informed consent was obtained from 130 consecutive cases scheduled for open inguinal hernia surgery. Patients were alternately assigned to undergo incision with electrocautery (group A) or a conventional steel scalpel (group B), with each group comprising 65 patients. Bilateral hernia cases were treated as separate entities. Data analysis was performed using Microsoft Excel and Statistical Package for Social Sciences (SPSS) software version 24.0, employing the Student’s t-test and Chi-square test. A p-value of &lt;0.05 was considered statistically significant. Results: The age distribution in group A was 49.69±15.74 years and in Group B was 52.81±14.25 years. The time taken for incision in the electrocautery group was much shorter at 12.57±11.55 seconds than in the scalpel group at 20.63±2.99 seconds, with a p-value of &lt;0.001. The average amount of blood loss in group A was 1.02±0.35 mL and in group B was 2.03±0.32 mL, with a significant p-value of &lt;0.001. The postoperative pain, calculated by the Visual Analogue Scale (VAS), showed a significant difference in the early postoperative period at 6 hours after surgery in Group A at 6.58±0.9 compared to group B at 7.05±1, with a p-value of 0.005. However, no significant difference was noted between the two groups at 12, 24, and 48 hours after surgery. There was no significant difference in scar evaluation between group A and group B at 12 weeks, with a p-value of 0.673 for the patient score and 0.189 for the observer score. Conclusion: Electrocautery can be recommended for hernia skin incision due to its advantage of shorter incision time, minimal blood loss, and less early postoperative pain.

Management of Ankyloglossia in a Non-Syndromic Patient Using a Super Pulsed Laser: A Life-Changing Treatment- A Case Report

Objective: Ankyloglossia affects a person’s overall well-being and life, from malnutrition due to poor feeding and mechanical problems to psychological stress and low self-esteem, thus affecting social life. This case reports the use of non-scalpel techniques, such as a super pulsed laser, to manage ankyloglossia in a non-syndromic patient suffering from speech incompetence and restricted tongue mobility and highlights its advantages over other conventional techniques. Case Report: A 17-year-old male patient presented with a complaint of restricted tongue mobility, due to which he could not pronounce certain words clearly. As the patient was apprehensive about the use of a scalpel, it was decided to manage ankyloglossia using a diode laser against the conventional scalpel technique. Thus, the laser-assisted lingual frenectomy using GaAs super pulsed laser was used to excise the lingual frenulum. Conclusion: This case report suggests that ankyloglossia can be successfully treated by using laser-assisted surgery and gives superior results specifically in terms of lesser pain and bleeding

Assessment of clinical outcomes and patient response to gingival depigmentation using a scalpel, ceramic bur, and diode laser 980 nm

ObjectiveThis research compares the clinical outcomes of gingival depigmentation procedures with conventional scalpel, ceramic trimmer bur, and diode laser techniques.Materials and methodsTwenty-four individuals with physiologic gingival hyperpigmentation received random allocation to one of three treatment groups: scalpel, ceramic bur, or diode laser. Pain score, operation time, bleeding index, degree of epithelialization, wound healing, Dummett-Gupta Oral Pigmentation Index (DOPI), and Takashi Index score changes were all investigated at different time points.ResultsAt 12-h follow-up, significant variations in pain scores were seen between the laser and scalpel groups (p = 0.003) but not between the laser and ceramic bur groups. The diode laser group completed the procedure significantly quicker than the scalpel and ceramic bur groups (p = 0.004 and p = 0.001, respectively). The ceramic trimmer bur and diode laser groups showed significantly less bleeding tendency than the scalpel group. Wound healing and the degree of epithelialization were similar in all groups. DOPI and Takashi indices significantly decreased compared to baseline in all groups, with no significant difference recorded between all groups.ConclusionWhile diode lasers are a safe and effective treatment option for gingival hyperpigmentation, providing optimal aesthetics with reduced discomfort to patients, a ceramic trimmer bur can also be used as a simple and affordable alternative to a laser in gingival depigmentation procedures.Clinical relevanceGingival hyperpigmentation is a major aesthetic issue for many individuals. Laser and ceramic trimmer bur treatments produce equivalent aesthetic outcomes for gingival hyperpigmentation.

Comparison of histopathological margins after resection of oral squamous cell carcinoma using sharp dissection versus mono-polar electrocautery in T1 and T2 tumors

The study aims to compare histopathological margins after resection of oral squamous cell carcinoma (OSCC) with different surgical techniques: conventional sharp resection (SR) with scalpel versus monopolar electrocautery (ME). Hence, the question arises whether thermal damage by performing monopolar electrocautery surgery will lead to close margins more frequently than by using scalpels. 152 patients were included in this study. All patients received a primary tumor resection either performed with SR or with ME. Surgical margins were distributed into two groups: ≥5 mm (clear margins) and < 5 mm (close or involved margins). For comparing homogeneous groups, we considered tumor localizations, diameter and depth of invasion. The results were statistically analyzed by applying the Wilcoxon-Mann-Whitney-U-Test. The distribution of tumor diameter and depth of invasion was equal in both groups. There was no statistically significant difference between the amount of free surgical margins using SR or ME (p = 0.884). According to this study, the use of the monopolar electrocautery for tumor resection in the oral cavity does not increase the rate of compromised resection margins compared to the conventional scalpel.

Management of inappropriate frenal attachment with conventional scalpel approach: A case report

The term "frenum" refers to a small fold or band of tissue that connects two structures within the body. These frenum can vary in size, shape and attachment points among individuals. In some cases, an oral frenum may cause issues such as restricted movement, speech difficulties, diastema (gap between teeth) or interference with orthodontic treatment. The frenum may jeopardize the gingival health when they are attached too closely to the gingival margin, either due to an interference in the plaque control or due to a muscle pull. The aim of this case report is to manage the inappropriate frenal attachment in single visit by conventional scalpel technique.

Comparison of Postoperative Complications between Conventional Diathermy Haemorrhoidectomy and Harmonic Scalpel Haemorrhoidectomy

Abstract Background For symptomatic grade III and IV haemorrhoids, some form of hemorrhoidectomy remains the accepted modality of treatment. The traditional methods like the Milligan-Morgan method and the Ferguson‟s method have been in practice for more than half a century. Recently we acquired the Harmonic system. It is an ultrasonic dependent technology, using waves to both seal and cut vessels and tissues in a hypothermic condition, now widely used for hemorrhoidectomy. This study will give a comprehensive overview on differences between conventional diathermy haemorrhoidectomy and Harmonic scalpel haemorrhoidectomy focusing on post-operative complications mainly postoperative pain, bleeding, anal stenosis and peri-anal fistulae occurrence. Objective To compere between conventional diathermy hemorrhoidectomy and Harmonic scalpel hemorrhoidectomy as regards post-operative pain, bleeding, anal stenosis and peri-anal fistula occurrence. Patients and Methods It is a prospective study conducted over 40 patients with grade III and IV hemorrhoids, randomly divided into two groups to compare between conventional diathermy hemorrhoidectomy, Harmonic scalpel hemorrhoidectomy as regards post-operative pain, bleeding, anal stenosis and peri-anal fistula occurrence. Results An overall favorable trend exists toward Harmonic scalpel hemorrhoidectomy in all parameters of the current study, in another word, the postoperative complications mainly pain, bleeding, anal stenosis and peri-anal fistula occurrence was much lesser in the Harmonic group. Conclusion Harmonic scalpel hemorrhoidectomy is a sutureless, hemorrhoidectomy technique dependent on an ultrasonic unit to achieve vessel and tissue sealing. It is safe and effective, has less blood loss, postoperative pain, bleeding, anal stenosis and perianal fistula occurrence compared to conventional diathermy hemorrhoidectomy.

Histological evaluation of mouse tongue incisions after Er:YAG laser surgery with different pulse energies versus after conventional scalpel surgery.

To identify the surgical instrument that allows for optimal healing of tongue incisions. An Er:YAG laser was compared with different pulse energies to a conventional scalpel for the incision of mouse tongue tissues. Mice were sacrificed through cervical dislocation at 24, 48, and 72 h postoperatively, followed by extraction of their tongues for incision experiments. The healing of the incisions and expression of inflammation- and pain-related factors in the tongues were compared between the surgical procedure groups. In laser-treated mice, tongue incisions healed the fastest when the laser output energy was 60 MJ per pulse. Macrophage chemotaxis toward the incisional area was triggered on the first postoperative day for the 60-MJ group, while the time for macrophage chemotaxis to the surgical area was later in the 80-MJ group. Tumor necrosis factor-alpha expression increased and then decreased in the 80-MJ group; however, it gradually decreased in the 60-MJ and conventional scalpel groups. Prostaglandin E2 expression increased and then decreased in the 80-MJ and conventional scalpel groups but gradually decreased in the 60-MJ group. The expression of transforming growth factor beta 1 gradually decreased in the 60-MJ and 80-MJ groups but gradually increased in the conventional scalpel group. Compared with surgical procedures using conventional scalpels, those using an Er:YAG laser with appropriate pulse energies can inhibit inflammation in the incisional area and promote incision healing. The use of an Er:YAG laser with appropriate pulse energies can alleviate intraoperative and postoperative pain in the incisional area.
