Clinical analysis of proposed classification of the lingual frenulum by index and percentage

Purpose to determine the clinical applicability of the proposed classification of the lingual frenulum by index and percentage. Methods the sample of this study consisted of 287 subjects of both sexes aged between 23 and 28 years. The lingual frenulums were classified based on two measures defined with aid of a compass and a digital caliper and it were analyzed in the formulas and proposed pattern from a research of corpses which resulted in formulas for index and percentage calculations. Results it was observed that the pattern established in the classification of lingual frenulum by the proposal is reliable by percentage. At the index classification a new pattern was found in the studied population. Conclusion after clinical application, it is suggested that the new pattern proposed by the index be adopted. In percentage proposal, the initial pattern should be maintained, providing effectiveness to both ways of classification of the lingual frenulum in speech-language practice.
