The aim of this study was to assess the prevalence and distribution of dental caries in subjects with thalassaemia major.
Clinical examination for dental caries, diagnosed according to the WHO criteria.
A total of 54 thalassaemic patients, 23 aged 6-9 (14 males and 9 females) and 31 aged 12-18 (17 males and 14 females) were examined.
dmft, DMFT and plaque scores.
The mean dmft was 6.92 for 6-7 year olds and 4.72 for 8-9 year olds. The DMFT values were 6.57 and 5.95 for ages 12-14 and 15-18, respectively. There was no statistically significant difference in caries prevalence (dmft/DMFT) between gender or between primary and permanent teeth. Only 17.4 per cent of the children aged 6-9 and 21.4 per cent of 12-18 years olds were caries free. The prevalence of dental caries in the thalassaemia patients was considerably higher (22.7 per cent) than that reported in a normal Jordanian sample (DMFT 6.26 vs 4.84). Very few fillings (1.4 per cent of the examined teeth) were observed, indicating a negligible rate of conservative treatment. More than half (61.1 per cent) of the patients had poor oral hygiene (plaque score > or = 2.0).
The need for effective preventive measures, education and dental treatment need to be stressed for this caries risk group.
本研究旨在评估重型地中海贫血患者龋齿的患病率及分布情况。
根据世界卫生组织标准对龋齿进行临床检查。
共检查了54例地中海贫血患者，其中23例年龄在6至9岁（男14例，女9例），31例年龄在12至18岁（男17例，女14例）。
乳牙龋失补牙面数（dmft）、恒牙龋失补牙面数（DMFT）和菌斑评分。
6至7岁儿童的平均dmft为6.92，8至9岁儿童为4.72。12至14岁和15至18岁年龄组的DMFT值分别为6.57和5.95。龋齿患病率（dmft/DMFT）在性别之间以及乳牙和恒牙之间均无统计学显著差异。6至9岁儿童中只有17.4%无龋，12至18岁儿童中这一比例为21.4%。地中海贫血患者的龋齿患病率（22.7%）显著高于约旦正常样本报告的患病率（DMFT 6.26对4.84）。观察到的补牙很少（占检查牙齿的1.4%），表明保守治疗率可忽略不计。超过一半（61.1%）的患者口腔卫生状况较差（菌斑评分≥2.0）。
对于这个龋齿高危群体，需要强调采取有效的预防措施、进行教育和牙科治疗。
