Abstract

Background: Gingival hyperpigmentation is a physiological pigmentation genetically, appearing with brown to black pigment on the gingiva and oral mucosa which is an aesthetic problem for patients. Purpose: This case report aims to discuss gingival depigmentation procedure using scalpel surgical techniques in patients with gingival hyperpigmentation. Case presentation: A 27-year-old female patient reported brown discoloration on the gums of her upper and lower front teeth which she had noticed ten years ago. Gingival depigmentation using scalpel surgical technique is performed to remove the pigment. Conclusion: Gingival hyperpigmentation is an aesthetic problem that is of concern to patients and requires surgical intervention to remove the pigment, one of them are gingival depigmentation with a scalpel surgery. Keywords: gingival depigmentation, gingival hyperpigmentation, scalpel surgery

Abstract

Streptococcus mutans and Porphyromonas gingivalis are major pathogenic bacteria involved in dental and periodontal diseases, such as caries and periodontitis. Chitosan derived from mangrove crab shells (Scylla serrata) is a natural biopolymer with potential antibacterial activity. This study aimed to evaluate the antibacterial effect of chitosan against Streptococcus mutans and Porphyromonas gingivalis based on inhibition zone diameters at concentrations of 0.25%, 0.5%, and 1%. An in vitro disk diffusion method was applied using 0.2% chlorhexidine as a positive control and distilled water as a negative control. The results showed that chitosan produced inhibition zones against both bacteria, with diameters increasing along with the concentration. The largest inhibition zone was observed at 1%, while smaller zones were formed at 0.25% and 0.5%. In conclusion, chitosan from mangrove crab shells exhibits antibacterial activity against Streptococcus mutans and Porphyromonas gingivalis, although its inhibitory effect remains lower than the positive control.
