<![CDATA[Upper incisor crown exposure is directly influenced by hard and soft tissue structures that surround andsupport these teeth. The amount of upper incisor crown exposure has a direct impact on dentofacial esthetics.Lip-tooth relationship during speech and smiling are important aspects of facial esthetics. Hence, the aimof this study was to evaluate the lip-tooth relations in subjects with different types of growth patterns usinglateral cephalograms. Methods-This was a retrospective study wherein case records of adult subjects aged18-35 years were involved. A total of 30 case records of patients who had reported to a university hospitalwere identified and included in the study. The records of subjects were divided equally into three groupsGroup A - horizontal growth pattern; group B - average growth pattern and group C - vertical growth pattern.All lateral cephalograms were measured using FACAD software. A chi-square test was used to determinethe association of lip-tooth relationships in various growth patterns. One-way ANOVA was used to comparethe incisor exposure in different growth patterns. One-way ANOVA reported a statistically significantdifference in lip-tooth exposure in various growth patterns (p=0, p<0.05). Similarly, chi-square test revealeda statistically significant association between lip-tooth relationships in various growth patterns (p=.00,p<0.05) Within the limitations of this study it can be concluded that there was an increased cervico-incisalexposure of incisors in vertical growth pattern as compared to average and horizontal growth patterns.]]>
