INTRODUCTION: Contemporary published data present confounding results on use of PRF in soft- and hard-tissue healing in the oral cavity, and many authors have suggested for further studies to reach the definitive conclusion. AIM: Our main objective therefore was to evaluate soft-tissue healing and osseous regeneration (by using VIXWIN PRO software) in extraction sites of mandibular third molars with substantial sample size to understand the effect of PRF in bony defects. METHODOLOGY: Sixty patients had their bilaterally impacted third molars (120 sites) extracted in the split mouth study, following which platelet-rich fibrin was placed in one of the sockets. Patients were followed up clinically and radiographically, and pain score, presence of infection, exudation of graft and VIXWIN PRO software were used to evaluate healing of soft tissue and bone. RESULT AND CONCLUSION: Our study advocates the use of PRF for enhanced soft- and hard-tissue healing. Though the osseous regeneration could be differentiated in both the groups at second month interval only, pain scores were better with PRF at most instances. Subsequent phase to the research should include histopathological investigations for ancillary support.

BACKGROUND: Information on the dimensions of the anterior loop of mental nerve is important for dental implant placement. AIMS: The purpose of this study was to determine the total length of anterior loop of mental nerve from the mental foramen. MATERIALS AND METHODS: CBCT data of 150 patients were evaluated. RESULTS: We found that the anterior loop was absent in 56.4% of patients on the left side and 61.7% patients on the right side. 19.5% of the total patients (29 patients) had up to 4 mm length of the loop which was exactly same on both right and left sides. The remaining 16.8% on the left side (25 patients) and 14.1% on the right side (21 patients) had the length of the loop ranging between 4.1 and 8 mm. The rest 7.4% of patients on the left side and 4.7% patients on the right side had more than 8 mm of the loop length. CONCLUSIONS: Based on this study, the dimensions of the anterior loop are variable and hold great significance in dental implant planning in the mandibular premolar region.

INTRODUCTION: Pain after surgical extraction of third molars has been a nemesis for oral surgeons with clinicians, thus striving for an analgesic modality. NSAIDs are among the most widely used therapeutic classes of analgesics. Transbuccal diclofenac sodium patches have been developed as an innovative drug delivery system using buccal mucosa as a gifted choice, hence overcoming first pass metabolism and offering the advantage of sustained drug delivery with reduced incidence of systemic adverse effects. AIM: A comparative study was conducted to evaluate the efficacy of diclofenac sodium for pain control, administered via the far-fetched and gifted novel route through the transbuccal patch and by ever popular per oral route and also to assess the adverse effects vis-à-vis for transbuccal diclofenac patch and oral diclofenac following extraction of bilaterally symmetrical impacted mandibular third molars under local anaesthesia. METHODOLOGY: Thirty healthy subjects of both the sexes in the age of 12 to 50 years with asymptomatic bilaterally symmetrical mandibular third molars underwent extraction under LA. It is a split-mouth study, i.e. after the extraction of tooth on one side, diclofenac sodium (50 mg) via oral route was given and then in another visit, when the same patient is comfortable and asymptomatic, extraction on contralateral side was executed and transbuccal patched diclofenac sodium (20 mg) was applied. Pain was measured on visual analog scale and verbal rating scale by the patient for 3 days and adverse effects if any were noted. RESULT: Statistical analysis showed that transbuccal diclofenac sodium was significantly efficacious when compared to the drug administered orally. Also, statistically significant results were obtained in percentage reduction in pain from 1st to 3rd postoperative day in transbuccal group. No significant difference is seen for adverse reactions. CONCLUSION: Transbuccal diclofenac sodium patch is more efficacious and can be used for pain control.

This prospective study aimed at presenting different treatment modalities and its association with the recurrence rate of KCOT. The study was conducted on 30 patients diagnosed with KCOT between March 2009 and 2012. The patients were followed up for a period of at least 1 year. The clinical, radiographic and demographic data were recorded and four different treatment modalities were followed to assess the recurrence of the tumour. In the study, KCOT showed male predominance with a male: female ratio of 23:7. Of the total cases, 26 (86.67 %) patients had parakeratinised KCOT and the rest 4 (13.3 %) patients had orthokeratnised KCOT. Nine (30 %) patients were reported with recurrence of the tumour within 1–2 years of surgery—all these patients had parakeratinised cyst. Recurrence was observed in four (50 %) out of eight cases of marsupialisation and four (44.44 %) out of nine cases of treatment using the enucleation process. No recurrence was seen in patients treated with resection; however only one out of three patients treated with enucleation, followed by fixation with Carnoy’s solution showed signs of recurrence. The histopathological examination determined the aggressive nature of KCOT and its association with the recurrence rate as well. The findings of our study indicate that more aggressive treatment can aid in reducing the chances of recurrence.

AIM: The purpose of this case series was to report the clinical and radiographical outcomes of vertical ridge augmentation in edentulous posterior mandible using a combination of titanium mesh with novabone putty. MATERIAL AND METHOD: Twenty patients were included, and grafting was done using alloplastic novabone putty supported by titanium mesh as the barrier for guided bone regeneration. RESULTS: Sixteen patients exhibited good soft tissue healing. Postoperative flap dehiscence occurred relatively early in the healing period in one patient followed by graft extrusion and delayed healing in other three patients. The mean vertical height of augmented bone was 4.825 ± 1.1387 mm. CONCLUSION: This report demonstrates the remarkable efficacy of guided bone regeneration using a combination of titanium mesh and novabone putty for vertical ridge augmentation, thus expanding the indications for implant therapy and allowing recovery of the three-dimensional esthetic architecture in a severely resorbed alveolar ridge.

AIM: This prospective study aimed at studying the complications associated with different techniques of anterior segmental maxillary osteotomy. MATERIAL AND METHOD: The study was conducted on 20 cases diagnosed with anteriorly prognathic maxilla with class 1 molar relation. The patients were followed up for a period of at least 1 year. The clinical and demographic data along with the intraoperative and postoperative complications associated with different treatment techniques were recorded. RESULTS: In five cases, Wassmund technique was followed with average time span of 32 min. Wunderer and Cupar technique took average time span of 23 min. Two patients presented with four non-vital teeth in a follow-up period of 1 year and one patient treated with Cupar’s technique had complication of palatal tear. Only one patient reported with relapse in a follow-up period and none of the patients had any complication associated with hemorrhage, neurosensory alteration or requiring plate removal. The findings of our study recommend ASMO as treatment modality of choice in patients with bimaxillary and/or dentoalveolar protrusion with Cupar’s technique providing more ease of operation.
