To evaluate the comparison of lip prints, palatal rugae pattern and dermatoglyphic patterns in different sagittal skeletal relationships in himachali population

Introduction: Dermatoglyphics analysis proven to be useful preliminary diagnostic investigation aid in conditions with a suspected genetic base. Palatal rugae serves as a stable landmark and are formed during similar time of intrauterine life as the teeth, so one can assume the relationship exist between the two. Similarly the lip prints are also unique to an individual just like fingerprints and shows a strong hereditary pattern. Aims and Objectives: To evaluate the comparison of Lip prints, Palatal rugae pattern and Dermatoglyphic Patterns in different sagittal skeletal relationships. Materials and Methods: A total of 90 patients, aged 12-18 years, were selected from those who attended the outpatient clinic of the Department of Orthodontics and Dentofacial Orthopaedics. The patients were divided into 3 groups as Class I, Class II, and Class III based on ANB angle. Palatal rugae, fingerprints and lip prints were recorded based on patterns in each group, then compared. Results: The correlation of vertical lip pattern with skeletal class III malocclusion was found. The wavy rugae pattern was most common in all skeletal groups. There was increased distribution of whorl pattern in the skeletal Class II and increased distribution of loop pattern in the skeletal Class III. Conclusion: A significant correlation was found between vertical lip pattern and skeletal class III malocclusion, and current study showed no specific palatal rugae pattern among the sagittal classes of skeletal malocclusion. There was significant correlation of whorl pattern in the skeletal Class II and loop pattern in the skeletal Class III.
