| Summary: | <b>Background:</b> The aim of this study was to evaluate the correlation between skeletal class and dental dimensions analyzed through linear, surface area, and volumetric measurements. <b>Methods:</b> The sample consisted of 90 patients with an average age of 18 years (44 > x > 12). The following tests were used to investigate any correlation between skeletal class and tooth size: Hoeffding’s test, Cramér’s V test, and analysis of variance (ANOVA), followed by Tukey’s post hoc HSD test and the logit model. The significance level was set at 0.050. <b>Results:</b> Cramér’s V test indicated a weak association between skeletal class (I, II, III) and total Bolton index (V = 0.167, <i>p</i> < 0.01). The ANOVA results showed that the total inferior volume and the anterior inferior volume were significantly greater (<i>p</i> = 0.012; <i>p</i> = 0.012) in skeletal class III (<i>p</i> = 0.012) than in the other two skeletal classes. The total upper surface area was significantly greater in patients with skeletal class III compared to those with classes II and I (<i>p</i> = 0.029). The anterior superior surface area was significantly greater in skeletal class III than in class II and I (<i>p</i> = 0.028). From the results of the logit analysis, it is possible to state that the third model is able to explain greater variability (21%) in terms of the distribution of results for the variables considered than the first (20%) and the second (14%). <b>Conclusions:</b> Class III skeletal malocclusions are characterized by increased tooth surface and volumetric dimensions compared to class I and class II. |
