The authors expose the results of an analysis made by measurements and volumetric calculations, of deciduous and permanent teeth, estimated at the level of the cementum-enamel junction and of the circumferences passing through the points of the occlusal and apical maximum convexity of the junction itself. It may be useful to remember free gingiva is that part of gingival sulcus included between the gingival margin and the bottom of sulcus, it is a tridimensional structure, having triangular section, where the gingival sulcus depth is the height and the thickness at the bottom of gingival sulcus is the base of the triangle. These measurements can be useful to examine closely the analysis of periodontal physiopathology.
作者公布了一项分析结果，该分析通过对乳牙和恒牙进行测量及体积计算得出，测量部位为牙骨质-釉质界水平以及经过该界牙合面和根尖最大凸度点的周长。需要记住的是，游离龈是牙龈沟位于牙龈边缘与龈沟底部之间的部分，它是一种三维结构，呈三角形截面，其中牙龈沟深度为三角形的高度，龈沟底部的厚度为三角形的底边。这些测量对于深入研究牙周生理病理学分析可能有用。
