Detection and evaluation of dental caries is of epidemiological importance. Its early detection is important to commence appropriate treatment planning. Cavitated, noncavitated, and initial lesions of dental caries can be detected by various indices.
The objective of the study was to assess the caries experience in schoolchildren using decayed-missing-filled teeth (DMFT)/decayed-extracted-filled teeth (deft), International Caries Detection and Assessment System-II (ICDAS-II), and Caries Assessment Spectrum and Treatment (CAST) systems.
An epidemiological survey was carried out among 1550 schoolchildren (37,644 teeth) between the age ranges of 4 and 14 years. American Dental Association type III examination was performed using plane mouth mirrors and community periodontal index probes using DMFT/deft, ICDAS II, and CAST indices.
Out of 37,644 teeth examined, 2,718 teeth had shown caries. Caries experience with DMFT/deft index was 5.54%. Highest score of DMFT was observed in deciduous dentition period (59.02%). Overall prevalence of dental caries with ICDAS and CAST system was 6.7% and 6.95%, respectively. The highest percentage of noncavitated lesions (ICDAS - 2.26% and CAST - 3.9%) and greater prevalence of caries among deciduous teeth (ICDAS - 53.2% and CAST - 58.7%) was observed with both ICDAS and CAST systems.
A high prevalence of noncavitated lesions and less number of sealants and restorations indicates the lack of awareness for prevention and treatment of oral diseases, which suggests a strong need for preventive and operative treatments.
龋齿的检测与评估具有流行病学意义。早期检测对于开始适当的治疗计划很重要。龋齿的空洞型、非空洞型和初期病变可通过各种指数进行检测。
本研究的目的是使用龋失补牙数（DMFT）/龋拔补牙数（deft）、国际龋病检测与评估系统-II（ICDAS-II）和龋病评估谱与治疗（CAST）系统评估学龄儿童的龋病患病情况。
对1550名年龄在4至14岁之间的学龄儿童（37644颗牙齿）进行了一项流行病学调查。使用平面口镜和社区牙周指数探针，采用DMFT/deft、ICDAS II和CAST指数进行美国牙科协会III型检查。
在检查的37644颗牙齿中，有2718颗牙齿出现龋齿。DMFT/deft指数的龋病患病情况为5.54%。DMFT得分最高出现在乳牙列期（59.02%）。ICDAS和CAST系统的龋齿总体患病率分别为6.7%和6.95%。ICDAS和CAST系统均观察到非空洞型病变的最高百分比（ICDAS - 2.26%和CAST - 3.9%）以及乳牙龋齿患病率更高（ICDAS - 53.2%和CAST - 58.7%）。
非空洞型病变的高患病率以及较少的窝沟封闭剂和修复体数量表明对口腔疾病预防和治疗的认识不足，这表明迫切需要预防性和手术性治疗。
