Abstract

Abstract:

Objective To explore the relationship between the height of alveolar bone resorption and sex and age in the adolescent dentition. Methods Multi-slice computed tomography （MSCT） was used to measure the height of alveolar bone resorption at labial, lingual, mesial and distal sites of teeth in 149 adolescents aged from 10 to 20 years. SPSS 25.0 software was used to analyze the relationship between the height of alveolar bone resorption and sex and age. Results There was no significant difference in the height of alveolar bone resorption between sex （P>0.05）. The height of alveolar bone resorption was positively correlated with age in all types of teeth. The model constructed by combining the alveolar bone resorption height data of four sites （y=2.569x₁+3.106x₂+4.108x₃+1.451x₄-0.082，R²_max=0.756）had a better ability to infer age than that of combining two sites （y=5.942x₁+4.489x₂+0.612，R²_max=0.706） and a single site （R²_max=0.638）. Conclusion The height of alveolar bone resorption is positively correlated with the age of adolescents. The combination of four sites has a stronger ability to infer the relationship between the height of alveolar bone resorption and age in adolescents and has higher accuracy in practical application.
