Percepção estética do manchamento decorrente do uso do diamino fluoreto de prata em molares permanentes

Abstract

The aim of this study was to compare the aesthetic perception of silver diamine fluoride (SDF)staining on occlusal surfaces of permanent molars by parents of children assisted at the Federal University of Santa Maria pediatric dentistry clinic, dentists, and academics. A convenience sample of nine extracted permanent third molars was selected according to the inclusion criteria of the absence of caries lesions, opacity or discoloration, except for three molars that should also have darkened occlusal fissures, compatible with International Caries Detection and Assessment System (ICDAS), score 2).Teeth were numbered and assigned for three experimental groups (n=3): G1: occlusal fissures with no changes; G2: stained occlusal fissures; G3: occlusal fissures treated with SDF. The teeth were subjected to visual examination, in random sequence and independently, by ten students of the Undergraduate Dentistry Course at the Federal University of Santa Maria (UFSM), ten dentists working in the city of Santa Maria, RS, and ten parents or guardians of children seen at the Pediatric Dentistry Clinic at UFSM. Each occlusal surface was classified as aesthetically acceptable or aesthetically unacceptable. The data obtained were analyzed using Kruskal-Wallis and Mann-Whitney tests, adopting a significance level of 5%. Minitab 19 software (Minitab Inc., State College, PN, USA) was used for calculations. Results: The parents' aesthetic perception was different compared to professionals and students for teeth from groups 1 and 2. Parents considered the teeth with no occlusal visual changes as unacceptable, however the three kind of evaluators had similar perception for teeth from group 3 (p=0.07),as most of teeth was classified as aesthetically unacceptable. Conclusion: The staining caused by SDF application on occlusal fissures is considered aesthetically unacceptable regardless of the evaluator.
