[Periodontal status in Rio de Janeiro city (Brazil)]. / Parodontalzustand in Rio de Janeiro City (Brasilien).

The periodontal status and the treatment needs were investigated in 1854 residents of Rio de Janeiro City (Brazil) by means of the CPITN. The results of the study showed that 2.5% of the examined individuals were healthy (CPITN 0), 8.1% displayed an increased tendency towards bleeding on probing (CPITN 1) and 23.2% presented with calculus and bleeding on probing (CPITN 2). Shallow pocketing (CPITN 3) was observed in 51.4% and deep pocketing (CPITN 4) in 14.7% of the examined subjects. Since 97.5% of the examined population were in need of periodontal therapy, the necessity for organizing an oral health program with emphasis on prevention and treatment of periodontal disease is strongly indicated.
