Palatoscopy, Odontometry, Forensic medicineAbstract
Palatal rugae and teeth are genetically determined. Palatal rugae are unique mucosal elevations seen on the anterior third palate. They are the most stable characteristics in the oral cavity. They can be used to evaluate the changes in teeth positions during orthodontic treatment. Also, palatal rugae can be used for human identification, in differentiation of population and gender determination.
Teeth are part of masticatory apparatus, the hardest tissue on the body, but chemically the most stable and durable even at high temperatures. Among the teeth canines shows the greater resistance to pathological alteration and trauma. Canines among all teeth have shown the greatest sexual dimorphism and moreover are least affected by caries and periodontal disease these attributes to make them reliable to be used to check sexual dimorphism.
The aim of the study is to establish identity of population using palatoscopy and odontometry.
Materials and methods: The present study involves 35 subjects between 12-16 years old. Palatal impressions are taken with alginate hydrocolloid and models are poured in dental cast of stone.
Results: The data analysis was performed in a statistical program Statistica 7.1 for Windows and SPSS 23.0. Significance is determined by p <0.05. The data are presented in tabular form.
The predominant rugae pattern in female was Straight rugae, in males Wavy rugae pattern also the predominant rugae pattern in Class I according to Angle was Wavy in males, Straight type in females same as in Class II Angle classification, Wavy type in male and Straight type in females
The mesiodistal width of right canine at females is larger than left canine. The mesiodistal width of left canine is larger than the mesiodistal width of canine on the right side. The mandibular intercanin width in male subjects is slightly higher than the corresponding value in female. All measurements in male were slightly higher than in female subjects.
Conclusion: In our study, palatoscopy revealed strong association with ethnicity, gender also with sagital skeletal jaw relation, thus predicting malocclusions that could be managed early with preventive and interceptive orthodontics. Also odontometric measurements mesiodistal width and mandibular intercanin width serve as e good tool in gender determination and should be used as additionally method in sex determination
