The effect of age on dental tissues was studied on histologic sections of totally impacted teeth obtained from patients between 11 and 76 years of age. Impacted teeth were used in order to obviate the influence of the environmental effects prevalent in the oral cavity. The presence of concentric denticles and diffuse calcifications was determined, and the width of secondary dentin, predentin, and cementum was measured. The width of predentin and cementum increased linearly with age, whereas the aging process of secondary dentin formation and diffuse calcifications followed a different pattern. The incidence of concentric denticles was identical for all age groups.
在取自11至76岁患者的完全阻生牙组织切片上，研究了年龄对牙体组织的影响。使用阻生牙是为了排除口腔中普遍存在的环境因素的影响。确定了同心牙本质小体和弥散性钙化的存在，并测量了继发性牙本质、前期牙本质和牙骨质的宽度。前期牙本质和牙骨质的宽度随年龄呈线性增加，而继发性牙本质形成和弥散性钙化的老化过程则遵循不同的模式。所有年龄组同心牙本质小体的发生率相同。
