Abstract
This study evaluated the surface integrity of sutures after immersion in mouthrinse or water by scanning electron microscopy SEM analysis Pieces of resorbable suture remaining after oral surgery were immediately collected Twelve pieces each of catgut chromed catgut and polyglactin 910 were divided into four groups and immersed in pure mouthrinse mouthrinse diluted in water at 11 and 12 or water positive control for 24 h Three pieces each of new sutures were used as negative control Specimens were placed on stubs and sputter coated with gold for SEM analysis Observation of experimental groups and comparison with controls revealed that immersion in the mouthrinse at different dilutions did not alter their surface slight nonsignificant changes were found in some experimental specimens yet also in the positive control group It was concluded that immersion of resorbable sutures in water or nonalcoholic benzydamine hydrochloride mouthrinse did not produce any significant change therefore this mouthrinse may be safely employed after oral surgeryThe authors would like to thank the nursing staff of the surgery service of HRAC/USP herein represented by nurse MSc Janir Biazon for the help in collection of remnants of sutures and Edimauro de Andrade for his help with utilization of the scanning electron microscope
