title: Evaluation of sutures after immersion in nonalcoholic benzydamine hydrochloride mouthrinse by scanning electron microscopy.
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 1:1 and 1:2, 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 non-alcoholic benzydamine hydrochloride mouthrinse did not produce any significant change; therefore, this mouthrinse may be safely employed after oral surgery.
