In Papua New Guinea the main dental problem has been periodontal disease and related conditions. Dental caries appears to be low in many community groups. The aim of this study was to explore the prevalence of dental caries and the periodontal health status of teenage schoolchildren in Port Moresby. 200 children of mean age 15.4 years were examined from two urban community high schools in Port Moresby. 44% of the children examined were caries-free and the average decayed, missing or filled teeth (DMFT) score was 1.43, while only 2.5% of the children had totally healthy periodontal tissues. 18% of them showed pathological periodontal pockets of 4 or 5mm in depth, the remaining children having either gingival bleeding, calculus or both. The results indicated that this group of children showed a low prevalence of dental caries and a high prevalence of periodontal problems. No cases with deep periodontal pockets of 6mm or more were found.
在巴布亚新几内亚，主要的牙科问题一直是牙周疾病及相关病症。在许多社区群体中，龋齿发病率似乎较低。本研究的目的是探究莫尔斯比港青少年学生的龋齿患病率和牙周健康状况。从莫尔斯比港的两所城市社区高中选取了200名平均年龄为15.4岁的儿童进行检查。接受检查的儿童中有44%无龋齿，平均龋失补牙数（DMFT）为1.43，而只有2.5%的儿童牙周组织完全健康。其中18%的儿童有深度为4或5毫米的病理性牙周袋，其余儿童有牙龈出血、牙石或两者皆有。结果表明，这群儿童龋齿患病率较低，牙周问题患病率较高。未发现有6毫米或更深牙周袋的病例。
