Benefits of Periodontal Therapy When Preterm Birth Threatens

Abstract

There is growing evidence that chronic periodontitis may be a risk factor for pre-term birth. The goal of this intervention study was to determine the effect of periodontal treatment on the pregnancy outcome in women with threatening pre-term birth and initial localized chronic periodontitis. Forty-one women with a singleton pregnancy were enrolled in the study. For this treatment group, oral hygiene instruction and periodontal therapy were provided in the third trimester, while those in the control group (42 persons) did not receive any periodontal treatment. In the treatment group, the mean weight of newborns was 3079.0 g, compared with the control group mean of 2602.4 g. The incidence of pre-term birth and low birthweight in the treatment group was significantly less than in the control group (p = 0.015). Periodontal treatment completed before the 35th week appeared to have a beneficial effect on birth weight and time of delivery.

Association between periodontal status and idiopathic male infertility

“…The selection of these variables was based on the design of previous studies. BOP is a known marker of periodontal inflammation (23)(24)(25). A PD ≥4 mm is considered "critical probing depth" (26), while lesser PD values are regarded as normal (27).…”

Oral colonization of Gram-negative anaerobes as a risk factor for preterm delivery

“…These results contradict smaller studies which showed significant differences between PTB and FTB following treatment. 186,188 Inconsistencies may arise due to population differences, severity of disease, different clonal types of bacterial species as well as differences in the management of patients. 191 The use of BANA for the screening of mothers at risk for PTB due to periodontal disease was recommended by Africa et al 73 and confirmed by Chan et al 13 The BANA test is based on the principle that members of the Red complex produce a trypsin-like enzyme which hydrolyses the substrate benzoyl-DLargenine-naphthylamide (BANA) producing a color change in the presence of 10 4 cell concentrations.…”

“…98 Women with periodontal disease, hospitalized because of the threat of PTB, were randomly assigned to two groups; one group received treatment for periodontal disease by way of oral hygiene instruction, scaling and root planing plus fluoride polishing while the other group received no treatment. 188 Treatment was provided in the third trimester. A significant difference in gestational age and weight of their infants was observed with those who had been treated delivering at 37.5 weeks with a weight of 3,079 g, while the untreated mothers delivered at 36.1 weeks with a birthweight of 2,602 g. From these studies, it would appear that treatment during the third trimester was more beneficial to the patient than treatment in the second trimester.…”

Influence of Socioeconomic Status on the Association between Prenatal Periodontal Care and Preterm Low Birthweight Delivery: A Population-Based Case-Control Study

“…An epidemiological study with a non-random sample in Taiwan from 2007-8 indicated that increasing age, poor toothbrushing knowledge and low socioeconomic status (SES) are potential risk factors of the disease (Lai et al, 2008). In spite of this, advantages of periodontal care during pregnancy on birth outcomes have been previously documented in clinical trials and intervention studies (Cruz et al, 2010;Jeffcoat et al, 2011;Radnai et al, 2009;Tarnnum and Faizuddin, 2007). Kim et al (2012) proved reduced risk only for high risk pregnant women in a meta-analysis of randomized controlled trials on scaling and root planing treatment.…”
