Article Synopsis
- - The study aimed to assess the prevalence of noncarious hard tissue lesions in the teeth of 776 university teachers in Shanghai, using WHO guidelines and SPSS16.0 for data analysis.
- - Results showed a significant average of 5.54 wedge-shaped defects per person and the highest caries incidence in first bicuspids at 29.52%. Lower incidences were noted for tetracycline pigmentation (3.09%), enamel hypoplasia (2.06%), and dental fluorosis (1.55%).
- - Overall, the incidence of wedge-shaped defects was higher than national data, while dental anomalies were lower, indicating a need for improved oral health care practices among university teachers in Shanghai.
