Cyanoacrylates have been recognized since before the 1960s as excellent tissue adhesives. They are easy to use, cost-effective, and cosmetically favorable. There are no studies from India reporting the use of tissue adhesives in laparoscopic surgery. We carried out a prospective, interventional, randomized trial of non-absorbable simple interrupted sutures versus 2-octyl cyanoacrylate in the closure of skin incisions in laparoscopic surgery with the primary objective of assessing the efficacy (approximation achieved) of both methods. The secondary objectives were to compare the operative time for closure, post-operative pain, infection and cost. There were 20 participants, 10 in either arm. Consenting patients undergoing elective laparoscopic surgery in a single surgical unit were included. Descriptive statistics were used on demographic data. Comparisons between the two methods were made on the basis of Southampton Wound Assessment Scale-SWAS grade for healing, Visual Analogue Scale-VAS scores for pain, intra-operative time, and cost. Apart from cost which was significantly higher for adhesive group, the groups did not differ significantly in terms of pain, wound approximation, and infection. Octyl cyanoacrylate is comparable to non-absorbable simple interrupted sutures in terms of closure time, post-operative pain, wound approximation and infection. The cost of using octyl cyanoacrylate is substantially higher than traditional suture material.

A major problem commonly observed in denture wearer is the detachment of artificial tooth/teeth from acrylic denture base. The problem was grave when porcelain teeth used along with the then available denture base materials. The bond formed was purely mechanical and hence debonding of teeth from denture base was a frequent occurrence. Inspite of chemical union between acrylic resin teeth and acrylic denture base material, detachment of teeth particularly anterior teeth is a frequent observation. The objective of the study is to study the effect of change in the surface treatment and surface configuration of ridge lap surface of the teeth on retention of cross-linked acrylic teeth on crosslinked acrylic resin denture base. Sixty specimens were tested for the shear compressive bond strength using instron universal testing machine in KN. Statistical analysis is used. The findings were analyzed using one-way analysis of variance (ANOVA) and ‘t’ test. Slight modification in the ridge lap surface of artificial teeth alters the strength of the shear compressive bond. Sand papering of ridge lap surfaces improves the shear compressive bond then the one without any modification. Maximum shear compressive bond strength can be increased by application of monomer How to cite this article Sadar L, Dhume S, Maniar N, Patil JP, Rane P, Gandhewar M.
