摘要

目的和目的:牙齿脱落可能对个人的身体和心理健康产生有害的影响。本研究的目的是分析在印度西部一所医疗机构牙科部就诊的患者拔恒牙的各种原因。材料与方法:选取2017年6月至12月在古吉拉特邦Valsad GMERS医学院门诊部行恒牙拔除术的患者，年龄15 ~ 84岁。拔牙的原因主要有:(1)龋齿;(2)牙周病;(3)创伤;(4)假理性;(5)正畸治疗;(6)牙髓治疗失败;(7)嵌套。 The patients were divided into 7 age groups (15-24; 25-34; 35-44; 45-54; 55-64; 65-74; 75-84 years). Results: A total of 869 teeth were extracted in 615 patients. 50.51% teeth were extracted due to dental caries and 38.43% teeth due to periodontal disease. Trauma and prosthetic reason accounted for 2.19% and 5.52% of teeth lost, respectively. Pericoronitis was the cause for extraction of 3.11% teeth. Nearly half of teeth (53.7%) were extracted due to dental caries in the patients less than 45 years of age (15-44 years group). Periodontal disease accounted for 81.4% of extractions in patients who were 45 years or older (45-84 years group). First molars were the most commonly extracted teeth (19.4%) followed by third molars (16%). Conclusion: Dental caries and its sequelae is the main reason for the extractions of permanent teeth followed by periodontal disease. As the age increases, periodontal disease becomes more important reason for tooth loss.
