Teza

The skeletal sample analysed in the present study belongs to the “Curtea Domnească” necropolis, discovered in 2008, during the archaeological excavations at the Palas Mall Complex in Iași (Iași County, Romania). 142 of second molar teeth (M.2), with dentine exposure, were analysed in order to estimate a diet pattern. Dental macrowear is a process of enamel tissue loss on the occlusal surfaces and it is often connected with lifestyles, habits, diet and food preparation techniques. The complex interactions between dietary habits and biomechanics during chewing are the main factors which influences the macrowear rates and dentine. The aim of this study is to evaluate the degree of dental wear using Scott's method for recording occlusal molar wear, computer-based image analysis method and scanning electron microscopy (SEM) technique. The percentages of dentin exposure (PDE) recorded on the M.2 molars suggest that the macrowear is sex related affecting both men and women individuals during growth but with a different intensity. Men are more affected by the dental wear than women. One-way ANOVA performed on ranked data showed significant differences at p<0.05. The scoring method for recording wear degree was strong correlated with the computer-based image analysis method and supported by SEM results. The significant difference in the M.2 molar degree of wear is probably mainly associated with the consumption of a differentiated diet, more abrasive and erosive in men than in women. Further research is required based on micromorphological analysis of the enamel and dentine (microwear analysis) through scanning electronic microscopy and computer-based image analysis.
