Selvig, KA, Zander,HA, Chemical Analysis and Microradiography of Cementum and Dentin from Periodontally Diseased Human Teeth. J. Perio. 33:303, 1962

Study aims

• is the mineral content in cementum and root dentin from healthy versus periodontally diseased the same
• using a radiomicrograph technique, determine the degree of mineralization and distribution pattern of the minerals.

Methods

• study done on 20 teeth from heavy calculus formers and had server periodontal disease. Three crosssectional slices were taken, according to Solheim this is ok to obtain cementum thickness. Also slices obtained to do chemical and microradiographic investigations to determine the calcium and magnesium and phosphorus content
• The control is taken from a previous study group in the chemical analysis.

Findings

• That the mineral content of the cervical portion indicated a higher mineral content (Ca+ Mg and P) in the periodontally involved teeth. And that microradiographic analysis shows x-ray dense zone at the surface of the cementum and exposed root dentin in most of the periodontally involved teeth.
• Thus, in the disease process, additional uptake of minerals at the root surface occurs.
