| Abstract: | Objectives: To asses whether dental eruption order can play a role in the early diagnosis of crossed laterality.
Study Design: Dental eruption pattern along with eye, ear, hand and foot lateralism were examined on 131 children between 6 to 8 years old from public schools from a multietnic population area of Barcelona city. Statistic methods (Statgraphics Plus 5.1 program) were used to evaluate data recollected.
Results: Only foot and dentition lateralities behave as independent variables regarding hand laterality. So dental eruption laterality (along with the foot one) would be one of the parameters more related to hand laterality given that dentition variable relationship is greater that the foot one. This suggests that tooth eruption could be more clinically relevant. Crossed laterality hand-foot is significantly more predominant in men (13%) than in women (1,6%). Meanwhile, the relationship between hand and dentition didn’t show any influence of sex.
Conclusions: Dental eruption order, can be used as a good parameter in the determination of the patient’s laterality.
Key words:Dentition, dental eruption, motor laterality, crossed laterality. |
