Overbite recognition and factors affecting esthetic tolerance among laypeople
The Angle Orthodontist
|November 21, 2022
Summary
Laypeople recognized anterior open bite (AOB) more than deep bite. Those with deep bite or unaware of it tolerated it better aesthetically, unlike AOB tolerance which was not significantly affected by other factors.
Area of Science:
- Dentistry
- Orthodontics
- Perception Psychology
Background:
- Deep bite and anterior open bite (AOB) are common malocclusions affecting dental aesthetics.
- Understanding laypeople's perception and tolerance is crucial for orthodontic treatment planning and patient satisfaction.
Purpose of the Study:
- To assess laypeople's ability to recognize deep bite and AOB.
- To determine aesthetic tolerance thresholds for these malocclusions.
- To identify factors influencing tolerance levels.
Main Methods:
- A questionnaire-based study with 100 lay participants.
- Assessment of overbite, recognition of deep bite and AOB, and aesthetic tolerance thresholds using grayscale images.
- Statistical analysis using stepwise logistic regression to identify influencing factors.
Main Results:
- High recognition rates for AOB (94%) and moderate for deep bite (55%).
- Participants with deep bite showed higher aesthetic tolerance (OR, 3.57).
- Recognition of deep bite correlated with lower tolerance (OR, 0.17); AOB tolerance was not significantly affected by other factors.
Conclusions:
- Aesthetic tolerance for deep bite is influenced by its presence and recognition.
- Laypeople with deep bite or unaware of it exhibit greater aesthetic tolerance.
- Further research may be needed to explore factors influencing AOB tolerance.

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
