Background: Lip types are typical for every person, and there are three basic lip phenotypes in humans. Uncertainty exists as to whether a general trend follows in the classification of lip according to the dental alignment. Aim: The purpose of this study was to assess the correlation between lip phenotype and the type of anterior tooth alignment. Materials and Methods: The study sample comprised schoolchildren aged between 10 and 14 years screened before the study and equally divided (n = 50) based on lip phenotypes given by Cutbirth classification on the basis of lip form as high, moderate, and straight lip. Parameters assessed included anterior well-aligned teeth, anterior malaligned teeth, crowding, spacing, midline diastema, increased anterior maxillary overjet, anterior deep bite, and retroclined anterior teeth. Scores for each of these morphologic characteristics were determined by direct measurement. Descriptive and analytical statistics were done. Results: The Chi-square test was used to check differences in proportions. The statistical significance was set at P < 0.05. Statistical significant correlations were observed between anterior tooth alignment and the lip phenotype. Conclusion: The malaligned anterior teeth were significantly higher in children with high and moderate lip phenotypes, whereas the well-aligned anterior teeth were a general trend that existed in children with straight lip phenotype.
