Objective:
To investigate the relationship between cervical lesions and patient age, brushing method and bruxism based on a clinical survey of first-appointment patients.
Methods:
Two hundred and nine patients (118 male, 91 female) who had unfilled cervical lesions were examined. Information on patient age, teeth with lesions, classification of the lesions, brushing method and bruxism was obtained. The data were analysed statistically.
Results:
Cervical lesions started to develop in the first premolar teeth in the early twenties and became more prevalent with age. A habit of bruxism was associated with an increase in cervical lesions. Brushing was not directly associated with the development of cervical lesions.
Conclusion:
This study suggests that cervical lesions should be treated at an early stage to prevent further problems.

01:21Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
01:11Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
01:15Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
