Resumo: |
This study aimed to compare clinical measurements of gingival thickness (GT) and distance between gingival margin and vestibular (GMBC-V) and interproximal bone crests (GMBC-I) with those using cone-beam computed tomography (CBCT).Material and methods: GT and GMBC-V were measured in 348 teeth and GMBC-I, in 377 tooth regions of 29 patients with gummy smile. GT was assessed using transgingival probing (TP), ultrasound (US) and CBCT, whereas GMBC-V and GMBC-I, by trans-surgical clinical evaluation (TCE) and CBCT. Statistical analyses used independent t-test, Mann-Whitney test, ANOVA Tamhane‟s post hoc test, Pearson correlation coefficient and simple linear regression.Results: Significant difference was observed for GT: between TP, CBCT and US considering all teeth; between TP and CBCT and between TP and US in incisors and canines; between TP and US in premolars and molars. No significant difference was observed between TP and CBCT in premolarsand molars. TP presented the highest means for GT. Significant positive correlation and linear regression were observed (p < 0.05) between TP and CBCT, TP and US and CBCT and US. Significant difference was observed for GMBC-V and GMBC-I using TCE and CBCT, considering all teeth and groups of teeth. Pearson correlation and linear regression were significant for GMBC-V and GMBC-I (p < 0.05), except in molars(r = 0.014; p = 0.915) and region between molars(r = 0.239; p = 0.071).Conclusions:Measurements obtained using CBCT and US presented lower means for GT than TCE. GMBC-V and GMBC-I means were higher using CBCT than TCE. |
