Objective:
The objective of this four-week, examiner-blind study was to determine the impact of an educational oral health program conducted within a Boys and Girls Club of America in Chicago, Illinois, USA. The educational program focused on the gingival health (gingivitis and plaque) of participating children who were between the ages of six and 15.
Methodology:
The multi-week program taught the participants the basics of oral biology and disease, as well as proper oral health prevention, including oral hygiene, dietary modification, and the importance of visiting the dentist. A calibrated examiner measured whole mouth Löe-Silness Gingival Index (GI) and Turesky Modification of Quigley-Hein Plaque Index (PI) at baseline (immediately prior to the initiation of the educational program) and four weeks later. The primary efficacy analysis was based on the change from baseline for 90 subjects who were enrolled at baseline, participated in the educational program, and were examined four weeks later. In addition, subjects completed five questions at baseline and at four weeks to assess their oral health knowledge before and after exposure.
Results:
Mean baseline GI score was 0.184, while the four-week mean GI score was reduced to 0.140. This represents a 24% reduction in GI score, with p < 0.001. The mean baseline bleeding site score was 9.99, while the four-week mean bleeding score was reduced to 7.97. This represents a 20% reduction in bleeding sites, with p = 0.005. The mean baseline PI score was 3.06, while the four-week mean PI score was reduced to 2.97. This represents a 3% reduction in PI score with p = 0.044. The subject population was found to have statistically significantly (p < 0.001) greater knowledge following the program at week four, with 37% (33 of 90) and 69% (62 of 90) of subjects answering the questions correctly at baseline and week four, respectively.
Conclusion:
Collectively, these data support the role of an educational program in promoting improved oral health in these children over a four-week period.

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...

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.
