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.

Antimicrobial Activity of Chlorhexidine and Herbal Mouthwash Against the Adherence of Microorganism to Sutures After Periodontal Surgery: A Clinical Microbiological Study

“…Raquel et al made similar experimental observations in 2009 [7]. Their study stated that both chlorhexidine and herbal mouthwash presented effective antimicrobial activity against the adherence of microorganisms to sutures, but herbal mouthwash was not as efficient as chlorhexidine mouthwash [7]. A statistically significant difference between the chlorhexidine mouthwash and the herbal group was observed.…”

“…Previous research on the action of chlorhexidine on aerobic and anaerobic gram-positive and gram-negative bacteria found that chlorhexidine had a high affinity for microorganism cell walls and caused cell surface alterations that resulted in osmotic imbalance and cytoplasmic precipitation. Raquel et al made similar experimental observations in 2009 [7]. Their study stated that both chlorhexidine and herbal mouthwash presented effective antimicrobial activity against the adherence of microorganisms to sutures, but herbal mouthwash was not as efficient as chlorhexidine mouthwash [7].…”

“…Post-operative care of the sutured wound is very important after surgery. Sutured wounds in the oral cavity are kept clean through frequent rinses with either normal saline, chlorhexidine mouth rinse, hydrogen peroxide diluted with saline, herbal mouthwash, or fresh tap water [ 6 , 7 ]. Mouth rinses are commonly used in conjunction with mechanical hygiene measures to help control supragingival plaque, gingivitis, and post-operative infection [ 8 , 9 ].…”
