Objective: The purpose of this investigation was to undertake an objective and quantitative evaluation of how severity of lower anterior face height (LAFH) variations influences perceived attractiveness.
Design: Cross-sectional study
Setting: St George's Hospital, London, UK PARTICIPANTS AND METHODS: The LAFH of an idealized male and female frontal facial image were altered in 2·5 mm increments from -20 to 20 mm (male images) and from -10 to 20 mm (female images), in order to represent reduction and increase in height of this region. These images were rated by a pre-selected group of pre-treatment orthognathic patients (n = 75), clinicians (n = 35) and laypersons (n = 75).

Objective: The aim was a quantitative evaluation of how the severity of lower facial profile convexity influences perceived attractiveness.
Study Design: The lower facial profile of an idealized image was altered incrementally between 14° to -16°. Images were rated on a Likert scale by orthognathic patients, laypeople, and clinicians.
The purpose of this investigation was to quantitatively evaluate the influence of completing the orthognathic treatment process on patients' perceptions of attractiveness and their desire for surgical correction. The mandibular prominence of an idealized profile image was altered in 2 mm increments from -16 to 12 mm, in order to represent retrusion and protrusion of the mandible, respectively. These images were rated on a seven-point Likert scale by 50 patients at T1 (pre-treatment) and T2 (6 months following orthodontic appliance removal).

- The study aimed to objectively assess how changes in the prominence of the mandible affect perceived attractiveness, using modified profile images rated on a scale by different groups.
- Significant findings suggest that minor adjustments in mandibular position (-4 to +2 mm) go largely unnoticed, but greater deviations call for surgical intervention, with specific thresholds identified for different observer groups.
- The research indicates a consistent view among observers that increased mandibular retrusion or prominence correlates with lower attractiveness, and emphasizes the need to prioritize patient perspectives in future evaluations.
Objective: To determine an objective and quantitative evaluation of how severity of chin height variations influence perceived attractiveness.
Materials And Methods: The chin height of an idealized male and female frontal facial image was altered in 2.5-mm increments from -12.
Purpose: The purpose of this investigation was to undertake an objective and quantitative evaluation of how severity of asymmetries affecting the mandible and chin point influence perceived attractiveness.
Materials And Methods: The mandible and chin point of idealized male and female frontal facial images were altered in 5-mm increments from 0 to 25 mm and to the left and right, to represent horizontal, vertical, and combined asymmetry affecting these regions. These images were rated on a 7-point Likert scale by a preselected group of orthognathic patients before treatment, clinicians, and laypeople.
Background: This study established the reliability and cross-cultural validity of a Japanese version of the Dental Fear Survey (DFS).
Methods: Two studies were carried out in separate populations. The first involved 166 Japanese dental and nursing students and assessed internal consistency and test-retest reliability.
Unlabelled: The purpose of this study was to determine reference data for dental age assessment (DAA) for the 16 year threshold in British caucasians.
Patients, Materials And Methods: One thousand seven hundred and twenty-two Dental Panoramic Radiographs of individuals aged between 4 and 24 years were re-used to establish reference intervals using the tooth development stages (TDSs) previously described [A. Demirjian, H.
