  • Title: Prevalence and severity of periodontal diseases and dental caries in Bangladesh.
    Author: van Palenstein Helderman WH, Joarder MA, Begum A.
    Journal: Int Dent J; 1996 Apr; 46(2):76-81. PubMed ID: 8930677.
    Abstract:
    This paper reviews the results of studies on periodontal diseases and dental caries in Bangladesh. Almost all subjects aged 12 to 19 years (82-95 per cent) and 35 to 44 years (98-100 per cent) had calculus. The various studies showed a wide range of prevalences (14-65 per cent) of subjects with deep periodontal pockets in the age group of 35 to 44. According to a median estimate of the prevalence of subjects with deep periodontal pockets (26 per cent), it can tentatively be concluded that Bangladesh belongs to the 20 per cent of countries in the world where periodontal conditions of the population are among the worst. To assess the caries experience, median DMFT-values of age cohorts from the various studies were calculated. Twelve year olds had a DMFT of 1.7, 15 to 19 year olds of 1.6, 20 to 34 year olds of 1.0 and 35 to 44 year olds had a DMFT of 1.4. These DMFT-values are considered to be upper limit values since they were almost exclusively obtained from urban and peri-urban populations. The age effects observed indicated that there might have been an upward trend in caries activity in (urban) children before 1980. Cohort effects indicating secular changes in caries experience over the last 15 years have not been observed. It is therefore tentatively concluded that the caries activity in Bangladesh has remained stable in the last 15 years.
