To determine the prevalence of oral pathologic findings in an ancient culture that inhabited the Atacama Desert.
A systematic examination was performed on the remains of 83 individuals unearthed from a prehistoric burial ground. A total of 57 skeletal remains achieved appropriate inclusion criteria, from which estimated age at death, gender, ante- and postmortem tooth loss, prevalence and location of caries, apical periodontitis sequela, alveolar bone resorption and attrition were recorded.
From the analyzed skeletal remains (13 male, 22 female and 22 not identifiable), the mean age estimated was 29.9 +/- 13.8 years. A total of 89.4% of them presented permanent dentition with a mean ante-mortem tooth loss of 9.0 teeth and a postmortem mean tooth loss of 14.4 teeth per subject. In all, 46.4% of the postmortem remaining permanent teeth (n = 237) showed caries lesions. Interproximal caries was most frequently observed (31.5%), followed by occlusal (25.9%) and cervical caries (19.4%). Root remnants were found in 23.1% of the cases. In addition, 58.0% of the adults presented attrition, 26.0% signs of apical periodontitis and 44.0% loss of alveolar bone support >5 mm.
The remains of jaws and teeth of the individuals examined in this study presented sequelae of severe oral health damage due to caries and periodontal disease.
确定居住在阿塔卡马沙漠的古代文化中口腔病理发现的患病率。
对从史前墓地出土的83具个体遗骸进行了系统检查。共有57具骨骼遗骸符合纳入标准，记录了其死亡时的估计年龄、性别、生前和死后牙齿脱落情况、龋齿的患病率和位置、根尖周炎后遗症、牙槽骨吸收和磨耗情况。
在分析的骨骼遗骸中（13例男性、22例女性和22例无法确定性别），估计平均年龄为29.9±13.8岁。其中89.4%有恒牙列，每位受试者生前平均牙齿脱落9.0颗，死后平均牙齿脱落14.4颗。总体而言，死后剩余恒牙（n = 237）中有46.4%出现龋损。最常观察到邻面龋（31.5%），其次是咬合面龋（25.9%）和颈部龋（19.4%）。23.1%的病例中发现牙根残留。此外，58.0%的成年人有磨耗，26.0%有根尖周炎体征，44.0%的牙槽骨支持丧失>5 mm。
本研究中检查的个体颌骨和牙齿遗骸呈现出因龋齿和牙周病导致严重口腔健康损害的后遗症。
