Palatal Rugae Pattern Based on Lineage

Abstract

Background: Palatal rugae pattern are stable, and unique oral topographical structures to an individual, like his or her finger prints. Palatoscopy are comparable to dental, fingerprint and DNA identification techniques. Aim: to knowledge the palatal rugae pattern based on lineage. Methods: This study is a cross sectional study that carried out  on 20 families. Each families consists of father, mother and their child  (boy or girl). Palatal rugae pattern was recorded using an alginate impression material and appropriate metal tray for all sample. Result: The percentage distribution of the pattern of palatal rugae of a child that resembles one of its parents is most often found in the wavy type that is in the father-child relationship (50%). The association of palatal rugae pattern with based on shape, in the father-child relationship (the coefficient coefficient value = 0.731; p = 0,000). and based on the unification (coefficient contingency value = 0.522; p = 0,006). For the mother-child relationship, the contingency coefficient value of the mother-child relationship, based on the shape (contingency coefficient =, 0.478; p = 0,639), this indicates that the weak relationship occurs between mother and child and is not statistically significant Conclusion: This result finds a derivative pattern that occurs in the pattern of rugae palatina between of fathers with children or between mothers and children, this can be an important tool in personal identification and determine the relationship of family lineage of a person.
