The objectives of this work are to determine the areas where plaque accumulates more on the tooth surface and the different types of plaque found between left- and right-handed children.
Regarding the material and method, 49 patients aged 4-10 years were studied. Plaque developer Tri Plaque GelTM was applied to all of them, reflecting the presence or absence of plaque, its maturation status, as well as
Distribution, and whether the patient is left- or right-handed. It was observed on the vestibular surface which was divided into five regions: mesial, distal, gingival vestibular, middle vestibular and incisal vestibule.
The results showed that the percentage of people who use the left hand was 84.60%, and the percentage of people who used the right hand was 79.53%. Patients with right-handed primary teeth had greater plaque accumulation in the first and fourth quartiles, with 80% in the first quartile and 88% in the fourth quartile. The second and third quarters provided the same results: 75.06% for both. With regard to the proportion of different types of
The colors of the plaque developer on the surfaces analyzed, we found: 57.69% pink, 37% dark blue and 5.31% acidic plaque, i.e. light blue.
Thus, it was possible to conclude from the study that patients, whether with mixed deciduous teeth or left deciduous teeth, brushed better in the first and fourth quadrants, while patients with right and mixed deciduous teeth brushed better in the second and third quadrants. Quarters. The vestibular and gingival surfaces of all teeth were where there was the greatest amount of biofilm accumulation.
