CPITN changes during pregnancy and maternal demographic factors 'impact on periodontal health

ABSTRACT

There have been speculations about the effects of hormonal changes and socio-demographic factors on periodontal health during pregnancy. According to the lack of sufficient epidemiologic information about the periodontal status of pregnant women in Yazd, this study was accomplished to determine the changes of Community Periodontal Index for Treatment Needs [CPITN] during pregnancy and evaluating the possible relationship between this index and demographic characteristics of the mothers. This was a longitudinal descriptive study. The samples included 115 pregnant women who were referred to health centers of Yazd, Iran. The mothers' data were obtained from a questionnaire consisted of 3 parts consent paper, demographic data and CPITN records. Examination was performed with dental unit light, flat dental mirror and WHO's scaled probe. In the beginning of the study, 60.1% of checked sextants had healthy gingival status. 25.9% had code1 and 14% had code 2. Code 3 and 4 were not seen in any sextants. There was a significant relationship between lower CPITN and higher maternal education, occupation and more frequencies of tooth-brushing but there was not a relationship between CPITN and mother's age and number of pregnancies. CPITN had a significant relationship with increasing of the gestational age. There might be a relationship between increasing the month of pregnancy and more periodontal treatment needs. CPITN Increasing during pregnancy shows the importance of periodontal cares during this period
