| Sumario: | Objectives: The aims of this study were to evaluate the cephalometric linear and angular measurements of lip morphology among Malaysian Chinese population. Study design: A retrospective study involving the collection and analysis of lateral cephalometric radiographs of Malaysian Chinese. Materials and Methods: Standardized cephalometric radiographs of 70 Malaysian Chinese adults were analyzed. Among them are 37 females and 33 males aged from 18 to 25 years who did not undergo any orthodontic treatment. Total 9 linear and 5 angular measurements were carried out on cephalometric radiographs using Winceph 8.0 software. Descriptive statistics and sexual dimorphism were analyzed using IBM SPSS Statistics Version 20.0. The reliability of the method was analyzed using Dahlberg's formula. Results: Statistically significant disparities were found in the lower lip to s-line, upper lip thickness and Z-angle. Other measurements showed some similarities and variations but no significant differences were observed. Conclusion: This study is an attempt to establish the description of cephalometric lip morphology for the Malaysian Chinese adults. Cephalometric lip morphology is precise for the ethnic group, but these values should not be interpreted as treatment aim.
