Data on the oral health status and treatment needs among Yemeni children are lacking.
To assess caries prevalence, treatment needs and gingival health status among school children in Sana'a City and to examine how these are affected by age, gender and khat chewing.
1489 children (6- to 14-year old) were randomly selected from 27 schools representing all nine districts of Sana'a City. Dental caries and treatment needs were evaluated using standard WHO oral survey methods. The plaque index (PI), calculus index (CI) and the gingival index (GI), recorded at the six Ramfjord's teeth, were used to assess gingival health status.
4.1% of the study subjects were caries-free. Prevalence of these was significantly higher among the males. Overall, mean dmfs, dmft, DMFS and DMFT scores were 8.45, 4.16, 3.59 and 2.25 respectively. The decayed component accounted for >85% of the scores. The highest dmfs/dmft means were found among the 6-8 years age group, while the highest DMFS/DMFT means were scored by the 12-14 years age group. The need for restorative treatment and extractions was high; the former was significantly higher among the females. All subjects had gingivitis; the mean PI, CI and GI were 1.25, 0.3 and 1.36 respectively. Khat chewing did not affect caries experience; however, it was significantly associated with higher PI, CI and GI scores.
The prevalence of caries, gingivitis and treatment needs among children in Sana'a city is high. More surveys in other Yemeni cities to generate comprehensive data are required.
也门儿童的口腔健康状况和治疗需求数据缺乏。
评估萨那市学龄儿童的龋齿患病率、治疗需求和牙龈健康状况，并研究年龄、性别和咀嚼恰特草对这些状况的影响。
从萨那市九个区的 27 所学校中随机抽取 1489 名 6 至 14 岁的儿童。采用世界卫生组织口腔调查标准方法评估龋齿和治疗需求。使用 6 颗 Ramfjord 牙记录的菌斑指数（PI）、牙石指数（CI）和牙龈指数（GI）评估牙龈健康状况。
4.1%的研究对象无龋齿。男性的无龋齿患病率明显更高。总体而言，平均 dmfs、dmft、DMFS 和 DMFT 评分分别为 8.45、4.16、3.59 和 2.25。评分中龋齿占比超过 85%。6-8 岁年龄组的 dmfs/dmft 平均值最高，而 12-14 岁年龄组的 DMFS/DMFT 平均值最高。需要修复治疗和拔牙的比例很高；女性的修复治疗需求明显更高。所有研究对象均患有牙龈炎；平均 PI、CI 和 GI 分别为 1.25、0.3 和 1.36。咀嚼恰特草并未影响龋齿患病情况，但与较高的 PI、CI 和 GI 评分显著相关。
萨那市儿童的龋齿、牙龈炎和治疗需求患病率较高。需要在也门其他城市进行更多调查以生成全面的数据。
