Maturation and mineralization of inferior wisdom teeth in women with connective tissue dysplasia across the age range

Abstract

Objective. It was necessary to give a comparative assessment of dysplastic manifestations in the maxillofacial region in women by clinical and microscopic methods.
Materials and methods.
The research involved 90 female patients with connective tissue dysplasia (CTD) established using the Kulback criteria in the age groups 15-20, 21-30, 31-40 years. All had phenotypic (large), facial, and dental (small) stigmas analyzed, by which a portrait of a modern female person at a young age was drawn. In the clinic, the number and length (by X-ray) of the roots, the number of cusps were measured. The shape, packing, 3D surface of enamel prisms of teeth 38 were analyzed using a scanning electron microscope and an atomic force microscope.
Results.
Tooth enamel of a person with CTD at 15-20 years of age contains small enamel prisms, the size increases only after 30 years of age. At age 21-30 years, enamel prisms are of the same size as at age 15-20 years (in length at 15-20 years χ2=9.76, p=0.0103 relative to the 31-40 years group; in width at 15-20 years χ2=10.18, p=0.0089 relative to the 31-40 years group). At the age of 15-20 and 21-30 years there are total sites of hypomineralization in tooth enamel, at 31-40 years the sites of hypomineralization have a local character (by the distance between enamel prisms in 15-20 years χ2=11.01, p=0.0052 relative to the group 31-40 years). It was established that more mature and mineralized prisms at 15-20, 21-30 years change the shape of less mature ones, which eventually acquire ugly outlines and mature in unfavorable and extreme conditions for themselves.
Conclusions.
Connective tissue dysplasia plays a significant role in the maturation rate and mineralization of the enamel of the lower wisdom teeth.
