Papillary Variant of Oral Squamous Cell Carcinoma of Alveolar Mucosa- A Case Report and Review

Mahalakshmi Loganathan — 2023-12-05

Papillary Squamous Cell Carcinoma (PSCC) is a less frequent subtype of Squamous Cell Carcinoma (SCC) with a more favorable prognosis compared to conventional oral squamous cell carcinoma. PSCC has a distinctive exophytic and papillary projection. The upper aerodigestive tract is the most commonly affected site with a higher incidence of occurrence in the larynx. The papillary variant of oral squamous cell carcinoma involving gingiva or alveolar ridge is relatively uncommon and less reported. Other differential diagnosis of papillary gingival masses is reactive gingival lesions and fungal infections. An accurate diagnosis is vital for both therapeutic and prognostic purposes. This article describes the case of papillary variant oral squamous cell carcinoma in a 75-year-old male in the maxillary alveolar region depicting histopathological features of exophytic growth with hyperplastic stratified squamous epithelium with basaloid cells invading the underlying connective tissue.

Intra-Oral Appliance for Mouth Opening in a patient with OSMF- A Case Report and Literature Review

Jigna Shah — 2023-12-05

This paper describes the use of a custom-made intraoral appliance to relieve the trismus of moderate-grade OSMF. A 20-year-old female patient reported a chief complaint of restricted mouth opening due to already diagnosed OSMF. The patient was not satisfied with intralesional therapy and physical mouth-opening exercises. Therefore, a custom-made intraoral mouth- opening appliance was designed and fabricated. The intra-oral appliance have a screw that on activation gradually improves the mouth opening. The device is biocompatible and cost- effective; nonetheless, patient participation is the essential need for good results. The mechanism of other externally and internally activated mouth-opening appliances along with their fabrication is also described.

Bridging the Gap: A Case Report of Tooth Replacement using Resin-Bonded Fiber- Reinforced Composite Resin

Vineet Sharma — 2023-12-05

This case report details the prosthetic replacement of a mobile mandibular left central incisor using a Fibre-Reinforced Composite resin (FRC) with a denture tooth pontic along with splinting of periodontally compromised teeth adjacent teeth. FRC is ideal because it offers excellent mechanical and esthetic properties, especially when combined with splinting for periodontally weakened teeth. The clinical procedure included selecting an acrylic denture tooth and bonding it to adjacent teeth using FRC without invasive tooth preparation procedures. The prosthetic tooth was shaped, polished, and finished to blend with the surrounding teeth, providing the patient with proper occlusion and esthetics. The patient experienced no discomfort or adverse effects during the follow-up period, and both the esthetic and functional outcomes were satisfactory. FRC offers a conservative, low-cost alternative to implant prostheses and can improve the patient’s long-term periodontal outcome. However, it is essential to note that regular follow-up visits and proper maintenance are necessary to prolong the lifespan of the restoration.

Oral Mucocele of Lower Lip due to Lip Biting Habit: A Case Report

Vivek Mehta — 2023-12-05

Mucoceles are minor salivary gland lesions commonly seen in children and young adults. It is characterized by the presence of single or multiple, dome-shaped and fluctuant nodules, mostly asymptomatic, with sizes ranging from 1 or 2 mm to several centimetres. Although benign, it has the potential to cause functional disturbances and can impair feeding and dietary habits. The most common site is the lower lip and they have no obvious gender predilection. The color varies from deep blue to normal pink and the reported duration of this oral lesion varies from a few days to several years. Recommended treatment is often surgical excision and it minimizes the risk of recurrence. A case of an 11-year-old boy presenting with mucocele of the lower lip due to lip biting habit has been presented to enhance awareness regarding the diagnosis and management of oral mucosal lesions.

Impact of Various Desensitizing Agents on the Micro-Tensile Bond Strength of Adhesive Systems: In-Vitro Study

Ashok A. Rathod — 2023-12-05

Objectives: To assess the influence of various desensitizing agents on the micro-tensile bond strength of various adhesive systems. Methods: Fifty extracted human permanent third molars, were sectioned at the cementoenamel junction in order to expose the mid-coronal dentinal tubules in parallel to the occlusal surface using a diamond disc and water coolant. The samples were divided into five groups and each sample was immersed in the respective desensitizing agent (Groups 1 to 5; Group 1- Distilled water, Group 2- Arginine calcium carbonate (Sensitive Pro-Relief Colgate- Palmolive, India, Group 3- Calcium sodium phosphosilicate (Repair and Protect, GlaxoSmithKline, India), Group 4- Strontium chloride hexahydrate 10% w/w (ICPA Health Products Ltd, India.), Group 5- Er,Cr: YSGG (Waterlase MD, Biolase, Irvine, CA, USA) with each group having a sample of n = 10. Each group was further divided into two subgroups (n = 5) based on the adhesive system (either a One-step self-etch adhesive (Xeno v+) (SE) or a two-step etch and rinse adhesive (Prime and Bond NT) (EandR)). Instron Micro tensile Tester was used to analyze the Micro-Tensile Bond Strength (MTBS) of the samples. Results: The bond strength of the control group (Group 1) was greater as compared to the other four groups, though statistically insignificant. There was a significant difference in the bond strength of the two subgroups (p<0.001) One-step self-etch adhesive (SE, Xeno V+) and two-step etch and rinse adhesive (EandR; Prime and Bond NT) adhesive. Conclusion: The use of desensitizing agents does not affect the micro tensile bond strength of adhesives used for the management of restoration of Non-Cervical Carious Lesions (NCCL). Microtensile bond strength with a self-etch adhesive system was significantly lower in the desensitized dentin irrespective of the agents used.

Removal of Calcium Hydroxide Medicament from the Apical Root Canal using Different Irrigation Methodologies: A Scanning Electron Microscopy Study

Aditya Youvaraj Shinde — 2023-12-05

Introduction: To evaluate the efficiency of different irrigants and agitation techniques in the removal of calcium hydroxide Ca(OH)₂ medicament from the root canal walls. Material and Methods: N=84 mandibular premolars were selected for this study. The root canal of these 84 premolars was cleaned up using the ProTaper rotary system up to the file size F3 and then filled with Ca(OH)₂ medicament. For seven days, the root samples were maintained at 37o C and 100% relative humidity. The sample was divided into four groups (n=20 each) using random allocation employing different agitation methods: Group 1- MAF - Master Apical File, Group 2 - PUI - Passive Ultrasonic Irrigation, Group 3 - CB - Canal Brush, and Group 4 - FF - F File. Each group was further subdivided into two subgroups based on the specific chelating agent employed: (a) 10% Citric Acid and (b) 17% EDTA. Longitudinal bisection was performed in the apical (lower) third of the root structure. Further, an assessment was done using SEM (scanning electron microscopy) to study the elimination of Ca(OH)₂. Kruskal- Wallis and Mann-Whitney tests were used for statistical analysis. Results: Groups 1 (MAF) and Group 3 (CB) showed a significant statistical difference (p<0.05) when compared to Group 2 (PUI) and Group 4 (FF). An insignificant difference (p>0.05) was seen between the performance of chelating agents (10% Citric Acid and 17% EDTA). Conclusion: Irrespective of the specific chelating agents employed, both the PUI (Passive Ultrasonic Irrigation) and FF (F File) agitation techniques exhibited superior efficacy in the removal of Ca(OH)₂ medicament from the apical (lower) third when compared to the CB (Canal Brush) and MAF (Master Apical File) methods.
