Radiographic Description of the Distribution of Aggressive Periodontitis in Primary Teeth
Objective:
To describe the prevalence by site and tooth of aggressive periodontists (AP) in primary teeth of children with AP, that will facilitate the early diagnosis of AP.
Study Design:
Radiographic evidence of AP by tooth and site of primary teeth of 29 children with AP was analyzed by gender, ethnicity, type of dentition (primary or mixed), alveolar bone site and type of tooth.
Results:
The range and mean ± standard error of number of sites and teeth per patient with AP were 4 to 28, 13.1±1.2 and 4 to 12, 8.3±0.5 respectively. The differences in prevalence of AP by gender, ethnicity, dentition and homologous sites at both sides of the mouth were not statistically significant (Chi square). AP was mostly diagnosed at the distal area of the maxillary canine, the proximal areas of the first maxillary primary molars, and the distal area of the mandibular first primary molar. The most affected teeth with AP were the first primary molars followed by the maxillary cuspid, and the second molars.
Conclusions:
Examination of children's primary teeth should include abnormal mobility, when found it should be followed by radiographic evaluation for the presence of AP, taking in consideration the present findings.

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...
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...
