ABSTRACT
Schwannomas are benign nerve tumors of schwann cell origin. Schwann cells are derived from neural crest and are therefore of neuroectodermal origin. 25-40% of all schwannomas arise in the head and neck region. The most common schwannomas are vagal schwannomas and cervical schwannomas in the head and neck region. Here we present two cases of head and neck schwannomas which were not identified as originating from any major nerve. The first patient had a schwannoma in the infratemporal region which was excised by performing transzygomatic approach, and the second patient had a schwannoma in the left lateral part of the neck which was excised using a cervical crease incision.
ABSTRACT
Aim: To report a unique case presentation of a complex-compound odontome with 526 denticles. Background: Odontoma is a hamartoma of the jaws that has both epithelial and mesenchymal components differentiating to form enamel and dentin. It is of compound and complex types. Rarely, the features of both the types are present together in what is called the compound-complex type of odontoma. Case description: The case report discussed here is that of a 7-year-old boy who presented with a compound-complex odontoma in the right posterior mandibular region. Conclusion: Timely diagnosis and prompt surgical treatment aid in preventing complications and bony expansion. Thus, proper histopathological examination is essential for the confirmation of odontoma. Recurrence of odontoma is rare and usually has a favorable prognosis if diagnosed early. Clinical significance: The odontome contained 526 denticles, the maximum reported in the literature so far, making this a case of extreme clinical significance.

ABSTRACT
OBJECTIVES: The objective of the present study was to evaluate the various approaches used for implant stage II surgery before the restorative phase. MATERIALS AND METHODS: A retrospective study was carried out using data from 486 patients who had undergone stage II implant surgery at Saveetha Dental College and Hospitals, Chennai. The age, gender, technique of implant recovery, and site of recovery were noted. The data were collected and statistical analysis was done using IBM SPSS version 24.0. RESULTS: The mean age of the patients was 39.9 ± 12.9.The most common approach used in stage II implant surgery was found to be a full thickness flap accounting for about 76.75%. Chi-square test for association between the site of implant and the technique used for recovery was statistically not significant (p value % 0.187). CONCLUSION: Given that there is some loss of keratinized tissue during a flapless tissue punch technique, the full thickness flap provides an opportunity to preserve the keratinized gingiva and to form a healthy marginal attachment mucosa around the implants.

AIM: The aim is to compare the clinical efficacy of diode laser and erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er, Cr:YSGG) laser for implant stage 2 recovery procedure. MATERIALS AND METHODS: A total of 30 patients who had undergone dental implant placement were included in this study. The subjects were randomly allocated into three groups. Group 1 patients (n = 10) had implant recovery using diode laser, Group 2 (n = 10) implant recovery with Er, Cr:YSGG and conventional scalpel method (n = 10) was the third group. The pain assessment was recorded using visual analog scale (VAS scale), time taken for the procedure, intra-operative bleeding, time taken for healing were recorded for the three groups. RESULTS: Data were tabulated and the results were analyzed using SPSS software version 26. Mann-Whitney U-test was used to compare the postoperative analgesic used, postoperative VAS score, the time taken for recovery and time taken for healing between the three study groups. Results were considered to be statistically significant when P < 0.05. Operation duration under Er, Cr:YSGG were much faster than the diode laser, however the results were not statistically significant (P = 0.051). The operation time under Er, Ch: YSGG and laser were faster than the conventional scalpel group (P = 0.000). The time taken for healing was faster in the Er, Cr:YSGG laser group than the diode laser and the scalpel group (P = 0.000). VAS scale at day 0 was higher in the conventional group than the two laser groups (P = 0.000). CONCLUSION: Considering the advantages of both these laser systems such as less anesthesia, less surgical trauma and faster healing, and post-operative comfort, lasers are an effective tool for implant stage two recovery techniques. However, since diode lasers are more cost effective when compared to Er, Cr:YSGG, diode lasers may meet the clinical needs when compared to hard-tissue lasers.
