“…One of the most important goals of smile design is to achieve posterior tooth display, allowing filling of the buccal corridors 12345. In order to reach this goal, it is necessary that the patient exhibits an optimal transverse dimension of maxillary dentoalveolar bone, as well as appropriate buccolingual inclinations of the posterior teeth 67891011.…”

ObjectiveThe aim of this study was to compare the buccolingual inclination of maxillary and mandibular molars in adults with different vertical facial types.MethodsCone-beam computed tomography images of 135 adult patients (age, 20–45 years) with skeletal Class I maxillomandibular relationships were assigned to normodivergent (n = 46), hypodivergent (n = 49), and hyperdivergent groups (n = 40) according to linear and angular sella-nasion/gonion-menton measurements. The normodivergent group consisted of 24 females and 22 males, hypodivergent group of 26 females and 23 males, and hyperdivergent group of 24 females and 16 males. Buccolingual inclination of the maxillary and mandibular first and second molars was measured relative to the occlusal plane. One-way analysis of variance was used for intergroup comparison. Gender differences were evaluated using independent t-tests.ResultsBuccolingual molar inclinations did not differ significantly between females and males (p > 0.05). There were no statistically significant differences among the buccolingual inclinations of the first and second maxillary and mandibular molars of the groups (p > 0.05).ConclusionsBuccolingual inclinations of maxillary and mandibular molars are similar in normodivergent, hyperdivergent, and hypodivergent adults with Class I sagittal relationships.

“…As regards only the perception of morphological characteristics as associated with male or female gender, it is interesting to note that we found no strong relation between our findings and the results of previously published studies which have investigated the impact of dental characteristics on smile esthetics. 18 However, poor oral hygiene, loss of interdental papilla and darker teeth color were associated with male sex, indicating that the social and cultural background plays a fundamental role in perception of sex. Some assumptions found a correspondence in published literature.…”

Aim The aim of this research was to evaluate the possibility of identifying the sex of 1 subject through visual assessment of a frontal photograph of dentition, and to investigate if some morphological characteristics are related to sex determination. Methods 5 expert dentists, 5 non‐expert dentists and 5 laypeople were made to watch 100 intraoral photographs for 5 seconds each and to establish their sex. The responses of the participants and the baseline characteristics of photographed dentitions were analyzed. Results The proportion of right answers was 56.0% ± 8.2% in the group of expert dentists, 65.0% ± 6.0% in the group of non‐expert dentists and 58.6% ± 4.5% in the group of non‐expert people. The round shape of maxillary central incisors was related to the female gender (P = .006). The male condition was correlated with poor oral hygiene for 4 observers. Female sex perception was correlated with round morphology of upper central incisors for 3 observers. Conclusion No difference in the ability to determine the sex was registered among groups, suggesting that sex perception is not strongly influenced by the characteristics of dentition.
