Abstract

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.

与性别识别相关的解剖学因素:一项口腔内标准化照片的研究。

目的本研究的目的是评估通过牙列正面照片的视觉评估来识别1名受试者性别的可能性，并探讨一些形态学特征是否与性别决定有关。方法让5名专业牙医、5名非专业牙医和5名普通人观看100张各5秒的口腔内照片，并确定其性别。分析了被试的反应和所拍牙列的基线特征。结果专家组正确率为56.0%±8.2%，非专家组为65.0%±6.0%，非专家组为58.6%±4.5%。上颌中切牙圆形与女性相关(P = 0.006)。4例男性患者口腔卫生状况与口腔卫生不良相关。女性性知觉与上中切牙圆形形态相关。结论各组对性别的判断能力无显著差异，表明牙列特征对性别感知的影响不大。

期刊介绍： Journal of Investigative and Clinical Dentistry (JICD) aims to publish quality, peer reviewed original research and topical reviews on all aspects of investigative and clinical dentistry and craniofacial research, including molecular studies related to oral health and disease. Although international in outlook, the Editor especially encourages papers from the Asia Pacific. The journal also aims to provide clinicians, scientists and students of dentistry with a knowledge transfer platform for rapid publication of reports through an international journal, which will be available free online until 2012. Its scope, therefore, is broad, inclusive and international, but with a particular focus on Asia Pacific. The Editor welcomes manuscripts in the following key thematic areas in oral and maxillofacial sciences: Community Dentistry and Oral Epidemiology, Conservative Dentistry, Dental Biomaterials, Dental Pedagogy, Endodontics and Traumatology, Implant Dentistry, Oral Biosciences, Oral and Maxillofacial Surgery, Oral Medicine, Oral Pathology and Oral Microbiology, Orthodontics, Oral Radiology, Oral Rehabilitation, Paedodontics, Periodontology and Periodontal Medicine.
