The purpose of this study was to assess the prevalence, distribution and intensity of tooth wear in a sample of an ancient Italian population in order to explain the pattern in terms of dietary habits and/or non-dietary tooth-use behaviors during the Early Bronze Age, with a focus on possible age-group and sex differences.
Well-preserved permanent teeth of individuals from the Bronze Age site of Ballabio (Lecco) in northern Italy were examined for tooth wear by different methods. Eight 3D models of teeth at increasing severity of wear were created.
In total, 357 permanent teeth belonging to male and female individuals were included in the study. Dental wear was present in 96.6% of the total sample. Males showed significantly greater levels of wear than females in the mandibular teeth. Both sexes exhibited a significantly different wear direction between the anterior (oblique and flat) and posterior (oblique and concave) teeth. Significant age differences were observed in the direction and level of wear in the incisors, canines and premolars, with higher wear in the older group. Complete and rotatable virtual 3D images of different wear patterns are proposed.
The findings of the present study confirm the data from archaeological studies on this site and on northern Italian habits during the Early Bronze Age suggesting a diet rich in vegetables. The observed wear patterns can be related both to the diet of this Bronze age population, based on hard and abrasive food requiring vigorous mastication, and to sex differences in cultural practices.
本研究旨在评估意大利古代人群样本中牙齿磨损的患病率、分布及严重程度，以便从青铜时代早期的饮食习惯和/或非饮食性牙齿使用行为方面解释这种模式，重点关注可能存在的年龄组和性别差异。
采用不同方法检查了来自意大利北部巴拉比奥（莱科）青铜时代遗址个体保存完好的恒牙的牙齿磨损情况。创建了八个磨损严重程度递增的牙齿三维模型。
本研究共纳入了357颗属于男性和女性个体的恒牙。在整个样本中，96.6%的牙齿存在磨损。男性下颌牙齿的磨损程度明显高于女性。两性的前牙（倾斜和平坦）和后牙（倾斜和凹陷）磨损方向均存在显著差异。在切牙、尖牙和前磨牙的磨损方向和程度上观察到显著的年龄差异，年龄较大组的磨损程度更高。提出了不同磨损模式的完整且可旋转的虚拟三维图像。
本研究结果证实了该遗址及青铜时代早期意大利北部习惯的考古研究数据，表明当时的饮食富含蔬菜。观察到的磨损模式既可能与该青铜时代人群基于需要大力咀嚼的坚硬和粗糙食物的饮食有关，也可能与文化习俗中的性别差异有关。
