From August to October 1991, the periodontal status of 1001 Yemenis representing the age groups 12-14, 15-19, 20-24 and 35-44 years was recorded and evaluated with reference to the CPITN, the calculus index and clinical attachment levels. The impact of chewing khat, the leaves of a cultivated, alkaloid shrub, and of using the traditional miswak chewing stick for oral hygiene purposes were investigated. The results show that 6.9% of the juvenile probands (15-19 years) had healthy periodontal tissue (CPITN 0), whereas bleeding on probing and calculus (CPITN 1 + 2) were registered in 86.2%. In the 35-44 year age group, 1.7% were periodontally healthy, whereas 84.5% displayed plaque retention or shallow pocketing (CPITN 2 + 3) and 12.5% deep pocketing (CPITN 4). The treatment needs in all age groups are confined primarily to calculus removal and instruction in oral hygiene. The clinical attachment level and the calculus index revealed age-related attachment loss and calculus formation, primarily among male probands. The higher khat consumption among the male population is reflected in its detrimental effect on the periodontal tissue, especially among younger probands. Oral hygiene aids have also an influence on periodontal status, with a toothbrush proving more efficient than the miswak. WHO efforts directed towards prophylactic programs need to be intensified but can be staffed by dental hygienists.
1991年8月至10月，记录并参照社区牙周指数（CPITN）、牙石指数和临床附着水平，对代表12 - 14岁、15 - 19岁、20 - 24岁和35 - 44岁年龄组的1001名也门人进行了牙周状况评估。研究了咀嚼巧茶（一种人工种植的含生物碱灌木的叶子）以及使用传统的阿拉伯树胶牙刷进行口腔卫生护理的影响。结果显示，6.9%的青少年受试者（15 - 19岁）牙周组织健康（CPITN为0），而86.2%的受试者探诊出血和有牙石（CPITN为1 + 2）。在35 - 44岁年龄组中，1.7%的人牙周健康，而84.5%的人有牙菌斑积聚或浅牙周袋（CPITN为2 + 3），12.5%的人有深牙周袋（CPITN为4）。所有年龄组的治疗需求主要局限于去除牙石和口腔卫生指导。临床附着水平和牙石指数显示存在与年龄相关的附着丧失和牙石形成，主要发生在男性受试者中。男性人群中较高的巧茶消耗量反映在其对牙周组织的有害影响上，尤其是在较年轻的受试者中。口腔卫生辅助工具也对牙周状况有影响，事实证明牙刷比阿拉伯树胶牙刷更有效。世界卫生组织针对预防项目的努力需要加强，但可以由口腔保健员来开展工作。
