Abstract
Background: The perception of facial aesthetics is a complex topic due to its subjective nature and it can be influenced by several factors. The purpose of this study was to compare the perception of general dentists, orthodontists, maxillofacial surgeons, and lay people by evaluating facial aesthetics in skeletal class III patients, especially for maxillary sagittal position. Methods: A survey consisting of three sets of pre-treatment photographs of four dysmorphic patients was used. The questionnaire was submitted to a total of 200 participants divided into the following four subgroups: general dentists, orthodontists, maxillofacial surgeons, and lay people. Their opinion on facial disharmony, sagittal position of the jaws, asymmetry of the chin, projection of the cheekbone area, and lip aesthetics was recorded. Results: Significant differences were found between experts and non-experts in the perception of the maxillary position, asymmetry of the chin and zygomatic area (p < 0.01). No statistically significant differences were found among the groups in the perception of mandibular position and lip aesthetics. Conclusion: The respondents with a medical or dental background perceived the presence of maxillary retrusion more than others. Only orthodontists and maxillofacial surgeons have recognized an alteration of the middle facial third as a greater component of skeletal class III malocclusion.
Highlights
Dentofacial deformities determine an alteration of the maxillomandibular complex, often causing functional and psychological problems for the patient [1]
This study aimed to evaluate the perception of maxillary position and facial aesthetics in patients with class III malocclusion by comparing the opinion of orthodontists, maxillofacial surgeons, general dentists, and lay people
The anteroposterior position of the maxilla has been extensively shown as a contributing factor to facial profile and aesthetics [4,12]
Summary
Dentofacial deformities determine an alteration of the maxillomandibular complex, often causing functional and psychological problems for the patient [1]. Gender, level of education, occupation, and ethnicity are subjective elements affecting the aesthetic facial evaluation For this reason, the facial perception could be different among laypeople, patients, and clinicians, with a multifactorial point of view [5]. The purpose of this study was to compare the perception of general dentists, orthodontists, maxillofacial surgeons, and lay people by evaluating facial aesthetics in skeletal class III patients, especially for maxillary sagittal position. The questionnaire was submitted to a total of 200 participants divided into the following four subgroups: general dentists, orthodontists, maxillofacial surgeons, and lay people Their opinion on facial disharmony, sagittal position of the jaws, asymmetry of the chin, projection of the cheekbone area, and lip aesthetics was recorded. Orthodontists and maxillofacial surgeons have recognized an alteration of the middle facial third as a greater component of skeletal class III malocclusion
