Unlabelled:
The study aimed to assess the prevalence and severity of periodontal disorders as well as possible correlations between periodontal status and parameters as follows: sex, age, dental group.
Material And Method:
Study group included 143 subjects (58-males, 84-females) aged between 15-65 years. The assessment of periodontal status was performed using CPITN indices (gingival inflammation, periodontal pockets depth) and Rateitschak indices (alveolar resorption degree visible on ortopantomographs). The correlations between age group, sex, dental group and CPITN indices, alveolar resorption degree and periodontal status were performed. Data were processed and submitted to statistical analysis.
Results:
The results regarding CPITN indices distribution were as follows: CPITN 0-6%, CPITN 1-8%, CPITN 2-22%, CPITN 3-47%, CPITN 4-17%. The results regarding alveolar resorption degree were as follows: absent-37%, small-28%, moderate-24%, severe-11%. The prevalence of chronic periodontitis was 60% and rapid progressive periodontitis were associated with 4.2% patients.
Conclusion:
The investigation of CPITN indices and alveolar resorption degree represent efficient tools for the assessment of periodontal status and treatments needs in epidemiological studies.

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...
