Objective. To assess the incidence of dentigerous cystic changes in the follicles of radiographically normal impacted mandibular third molars. Methods. One hundred and thirteen follicles obtained after surgical removal of impacted mandibular third molars with radiolucency of less than 2.5 mm in the radiograph were sent for histopathologic evaluation to evaluate pathologic changes. Results. The incidence of dentigerous cystic changes observed was 15.9%, that is, 18 out of 113 patients (51 males and 62 females), with the maximum incidence of cystic changes seen in the follicular space size of 0.5 mm. The mean age of the patients included was 27.8 ± 8.1. The most common indication for extraction among the patients in this study was recurrent pericoronitis (95%). There were no statistically significant differences in occurrence of cystic changes based on age, gender, angulation, relation to ramus, depth, side of impaction, and follicle size (P>0.05). Conclusion. Dental follicles obtained from surgically removed impacted mandibular third molars should be submitted for histopathologic examination irrespective of the radiographic size of the follicle.

The purpose of this study was to test the effect of the surgical removal of impacted mandibular third molars using piezosurgery versus the conventional surgical technique on postoperative sequelae and bone healing.Material and Methods.This study was carried out as a randomized controlled clinical trial: split mouth design. Twenty patients with bilateral mandibular third molar mesioangular impaction class II position B indicated for surgical extraction were treated randomly using either the piezosurgery or the conventional bur technique on each site. Duration of the procedure, postoperative edema, trismus, pain, healing, and bone density and quantity were evaluated up to 6 months postoperatively.Results.Test and control sites were compared using pairedt-test. There was statistical significance in reduction of pain and swelling in test sites, where the time of the procedure was statistically increased in test site. For bone quantity and quality, statistical difference was found where test site showed better results.Conclusion.Piezosurgery technique improves quality of patient’s life in form of decrease of postoperative pain, trismus, and swelling. Furthermore, it enhances bone quality within the extraction socket and bone quantity along the distal aspect of the mandibular second molar.

Objectives: The objective of the study is to revisit the forgotten art of Lingual split bone technique during the COVID pandemic as a Standard Operating Procedure (SOP) for the surgical removal of impacted mandibular third molars. It was originally introduced in early 90’s by Sir William Kelsey Fry and also we have compared its advantages over the bone guttering technique. Materials and Methods: Twenty seven cases were operated during COVID pandemic in our institution using Davi’s modified lingual split technique under strict COVID protocol. Results: All impacted mandibular third molars were successfully removed. With regards to post-operative complication; 3 patients had nerve injury (11%), 2 patients had lingual paraesthesia (7.6%), 1 patient had alveolar osteitis (3.8%), 2 patients had postoperative infection (7.6%), 3 patients had trismus (19%). The overall success rate was 100%. Also the results of a comparison between bone guttering and chisel-mallet technique were stated. Conclusion: The use of lingual split bone technique deserves consideration during this COVID time as an alternate for bone guttering in surgical removal of third molar as it ensures minimal cross infectivity rate among both dentists and patients. Thus, patient care can be delivered with confidence even during pandemic.

Introduction: The surgical removal of impacted mandibular third molars is an invasive procedure that involves extensive tissue trauma and a considerable postoperative inflammatory response. Although the inflammatory process is necessary for healing when exacerbated it may cause pain, swelling and limited mouth opening. Corticosteroids are among the most widely employed pre-operative medication administered for the control of such complications. Objective: To compare the effects of single dose of pre-operative Injection Dexamethasone versus Injection Methylprednisolone via Intramuscular or Submucosal route for controlling the post-operative pain, swelling and limited mouth opening in the removal of impacted mandibular third molars. Material and Method:. The present study was conducted on 40 healthy adult patients with bilaterally symmetrical impacted mandibular third molar, reporting to the Department of oral and Maxillofacial Surgery of Guru Nanak Dev Dental College and Research Institute, Sunam. Clinically, pain, swelling, mouth-opening were evaluated pre-operatively as baseline and post-operatively on 1st, 3rd and 7th post-operative days. Results: The results of our study are summarized below: In Group A: Submucosal injection of dexamethasone gave better results in controlling pain, swelling and trismus in comparison to Intramuscular injection of dexamethasone. In Group B: Submucosal injection of methylprednisolone showed better results in terms of pain, swelling and trismus when compared with Intramuscular injection of methylprednisolone. In Group C: Intramuscular injection of dexamethasone gave better results in terms of pain and mouth opening but, swelling was reduced with Intramuscular methylprednisolone. In Group D: Submucosal injection of dexamethasone showed better results in terms of pain, but swelling and mouth opening was reduced when methylprednisolone was used submucosal. Conclusion: The results of our study concluded that Dexamethasone is better than Methylprednisolone in controlling post-operative sequelae after third molar surgery. This can attributed to the higher potency and longer half-life and less sodium retaining capacity of dexamethasone than methylprednisolone. The results of our study also concluded that submucosal route of administration of drug is better than Intramuscular route because of the repository effect of the submucosal route, also this route is beneficial to the patient as well to the surgeon because needle penetration is done in the pre-anesthetized area, also it is an easy technique to be mastered by the surgeon.

Objectives: This study sought to assess the thickness of buccal and lingual alveolar bone plates according to the position of impacted mandibular third molars on cone-beam computed tomography (CBCT) scans. Materials and Methods: Eighty-four CBCT scans of impacted mandibular third molars were evaluated in this retrospective study. All images had been obtained by ProMax 3D CBCT system with the exposure settings of 78 kVp, 12 mA, 16 s time, 0.2 mm voxel size and 10 × 9 cm field of view. The impaction angle of teeth and the thickness of buccal and lingual cortical plates were determined on images by drawing lines in the anterior, middle, posterior, superior, central and inferior regions. Thickness of bone plates was analyzed according to the position of impacted molars relative to the buccal and lingual plates using the Student t-test and relative to the second molars using one-way ANOVA and Tukey’s test. Results: In the buccolingual direction, the buccal plate thickness was maximum in lingual position followed by central position, and minimum in buccal position of the teeth. The lingual plate thickness was minimum in horizontal and distoangular positions and maximum in the mesioangular position of impacted teeth. Conclusion: Risk of lingual plate preformation is higher in surgical removal of impacted third molars with distoangular and horizontal positions. Thus, further attention must be paid by the surgeons to such cases.
