Title: Investigating the effect of handedness on the dental caries pattern, gingival index and plaque index in 6-10 years old children
Objectives: It seems that the right-handed and left-handed individuals have different ability in brushing and removing plaque at different areas of the mouth. This study was conducted to evaluate the effect of handedness on dental caries pattern, gingival and plaque indices in 6-10 years old children.
Methods: Children with 6-10 years old age who had inclusion criteria were selected. Handedness of the subjects was determined using Edinburg method. Dental caries, plaque and gingival indices were also measured and recorded for each child. Then the relationship between handedness and the recorded variables were evaluated.
Results: The results showed that there is no significant relationship between any of the variables with being left or right-handed. A significant relationship was observed only between the lowest plaque index and handedness (P.value < 0.05).
Conclusion: A relationship cannot be considered between handedness of children and their oral health status.
