A pilot survey of oral health included 83 adolescent and adult Aborigines (41 M, 42 F, range 16--70 years, mean age 37.3 years), resident in fringe settlements around the far western New South Wales towns of Brewarrina and Walgett (fluoride in water less than or equal to 0.02--0.26 parts/10(6)). Dental caries prevalence (mean DIMFT per person) increased from 17.1 at 20 years to 10.7 at 35 years and declined to 14.6 by the age of 50 years and over. Oral hygiene (OHI) was poor overall and deteriorated with age. Periodontal status (PI) was significantly correlated with the presence of debris (DI) and calculus (CI). The mean PI increased from 1.7 at 20 years to 4.8 at 43 years and over. Tooth mortality reached 75% by the age of 43 years. Prosthetic needs were correspondingly high, but 95% of denture requirements were unmet. No evidence of effective or sustained oral health care was seen; 38% of subjects needed emergency treatment.
一项口腔健康初步调查涵盖了83名青少年及成年原住民（41名男性，42名女性，年龄范围16至70岁，平均年龄37.3岁），他们居住在新南威尔士州西部偏远城镇布鲁瓦里纳和瓦尔格特周边的边缘定居点（水中氟含量小于或等于0.02至0.26 ppm）。龋齿患病率（人均平均龋失补牙数）从20岁时的17.1上升至35岁时的10.7，到50岁及以上时降至14.6。总体口腔卫生状况（口腔卫生指数）较差，且随年龄增长而恶化。牙周状况（牙周指数）与牙菌斑（牙菌斑指数）和牙结石（牙结石指数）的存在显著相关。平均牙周指数从20岁时的1.7上升至43岁及以上时的4.8。到43岁时牙齿缺失率达到75%。修复需求相应较高，但95%的义齿需求未得到满足。未发现有效或持续口腔保健的证据；38%的受试者需要紧急治疗。
