Aim:
The aim of this study was to determine the influence of an oral hygiene motivation model on removing dental plaque in 57 subjects with an age range from 4 to 16 years, divided into three age categories on the basis of dentition phases, and to analyse the differences in behaviour between the three age groups and between sexes. MATERIALS AND METHODS Patients were instructed on how to carry out effective oral hygiene and were examined using the O'Leary plaque index at baseline (t0), 1 week, 1 month and 3 months later. At t0, examiners promised a present to the children if after 1 month they had better level of oral hygiene. After 1 month, the trainers gave a present to the children that had better level of oral hygiene. No gift was promised for the next visit at 3 months for evaluating if brushing teeth regularly had become an habit. Statistical analysis of the results was performed using ANOVA.
Results:
At t0, the mean O'Leary plaque index was very high; after 1 week, this value had already decreased; after 1 month it slightly decreased; after 3 months, the mean O'Leary plaque index was still low.
Discussion:
Children cleaned correctly their teeth both when examiners promised them a present, and when no gift was promised. Nevertheless, the mean value of the lower index of plaque was recorded after the first month, showing the children's susceptibility to the prizes. Females had better oral hygiene than males.
Conclusions:
This oral health motivation method was effective in establishing good oral health habits among children.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
