Sažetak
The purpose of this study was to assess the correlation between the known chronological age and the dental cementum thickness (DCT) in male and female subjects in different age groups. Material and methods: The study sample consisted of 57 donor teeth of both sexes. Teeth were lassified by donors’ sex and divided into three age groups: 10-19, 30-39 and 60-69 years. Tooth roots were cut with transverse ground sections in the apical, middle, and cervical thirds. DCT measurements were made on hotomicrographs of light microscope. The correlation between DCT and the chronological age was calculated using the Spearman correlation coefficient. Results: A positive correlation was found (r=0.47, p <0.001) between DCT and age of the donor. DCT decreased from apical to cervical ground section (median [IQR] apical section 216.72 [128.25-375.00] μm, middle section 158.44 [87.66-284.90] μm ; cervical section 96.60 [70.05-165.59] µm). DCT variability was influenced by sex, number of tooth roots and the condition of the tooth crown. The influence differed depending on the location of the section, being most prominent cervically. Conclusion: The present study showed correlation of DCT with age, with significant influence of sex, number of tooth roots, condition of the tooth crown and location of the root section.
