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.

研究目的：明确基于指数与百分比法提出的舌系带（lingual frenulum）分类方案的临床适用性。
研究方法：本研究纳入287名男女受试者，年龄介于23至28岁之间。研究人员借助圆规与数字游标卡尺，基于两项借助该工具定义的测量指标对舌系带进行分类，并结合此前一项尸体研究得出的公式与分类标准开展分析，最终得到可用于指数与百分比计算的相关公式。
研究结果：经观察发现，基于百分比法的舌系带分类标准具有可靠性；而基于指数法的分类体系在本次研究人群中发现了全新的分类模式。
研究结论：经临床应用验证后，建议采用本次研究基于指数法提出的全新分类模式；而基于百分比法的初始分类标准可继续沿用，二者均可为言语治疗临床实践中的舌系带分类工作提供有效支撑。
