The relation between hereditary factor and palatally impacted maxillary canine

Natheer A. Rasheed

Abstract


Background: it has been well known that there are different etiologies for palatal impaction of maxillary canine ,and one of the most important is the hereditary factor ,but all the previous studies have dealt with the hereditary factor as a presence of ; family history of palatal impaction of maxillary canine , and or missing or peg shaped upper lateral incisor[s}. In this study it was dealt with hereditary factor as if there is a relativity of parents of the patients who have palatally impacted canine.

Materials and methods : the data were collected during a thirty months interval by the examination of 2800 orthodontic patients in Baghdad city and Al-Faluja distinct, 867 male and 1933 female, age ranged between 14 and 29 years .

Results: 44 patients had PIMC, it was found that 63.6% of them had a related parents (cousin marriage), 70.% of them were not presented with clinically diagnosed etiological factors, the majority of these factors were the congenital absence or malformation of maxillary lateral incisor, and the incidence of occurrence were different between male and female .

Conclusion: these observations made us to embark on genetic theory a major role in production of this phenomenon.
