Evaluation of efficacy of 2% lidocaine gel and 20% benzocaine gel for topical anesthesia

Aim: The objective of this study was to determine the pain produced from needle insertion at bilateral labial site prepared with topical application of 2% lidocaine gel, 20% benzocaine gel, and placebo paste at subsequent visits in a same patient. Materials and Methods: Forty healthy individuals aged 18-30 years old were subjected to three sessions in which they were treated with 2% lidocaine gel, 20% benzocaine gel, and placebo paste. in all sessions, a 26-gauge needle was inserted in maxillary labial mucosa before and 1 min after the drug application. Immediately, after needle insertion, participants indicated pain intensity on visual analog scale (VAS). Results and Conclusions: Pain responses were compared based on subjects′ self-report using VAS. Results showed that lidocaine and benzocaine were equally effective, and both were better than placebo in reducing the pain of needle insertion.

Role of genioplasties in various chin deformities

Aim and Objectives: The goal of surgical-orthodontic treatment of chin deformities is to achieve maximum function, esthetics, and stability. The objective of our study is to evaluate the role of genioplasties in various chin deformities. Materials and Methods: Twelve adult patients who manifested various types of chin deformities were treated. In eight patients, advanced genioplasty alone or in combination with other surgical procedures such as premaxillary osteotomy, gap arthroplasty, bilateral vertical ramus osteotomy, and advancing and sliding genioplasty was performed. Four patients were treated by reduction genioplasty alone or in combination with vertical ramus osteotomy. Results: Results were more predictable and stable in case of chin advancement procedures as compared to reduction genioplasty. Conclusion: It was observed that the chin should not be completely denuded, muscular attachment on the lower part of the chin should always be maintained, if possible.

The Effect of Different Post Materials and Cements on Fracture Resistance of Endodontically Treated Teeth - an in Vitro Study

Objective: To evaluate the effect of various post materials and cements on fracture resistance of endodontically treated teeth. Material and Methods: Three post systems; custom made Ni-Cr post and core, prefabricated stainless steel and carbon fibre post with composite core and two different luting cements i.e glass ionomer and resin cements were used. Results and Conclusions: Carbon fibre post cemented with resin cements showed higher failure load than Ni-Cr and stainless steel post and resin cement performed better than glass ionomer cement, the mode of fracture was more favourable with carbon fibre post than in metallic post.
