Insights
Poor oral health, including gingivitis, periodontitis, and tooth loss, is linked to an increased risk of preterm delivery in pregnant women. Maintaining good oral hygiene during pregnancy is crucial for preventing adverse birth outcomes.
Area of Science:
- Obstetrics and Gynecology
- Periodontology
- Public Health
Background:
- Preterm delivery is a significant global health concern with multifactorial causes.
- Emerging evidence links maternal oral health conditions, such as periodontal disease and tooth loss, to adverse pregnancy outcomes.
- This study investigates the relationship between oral health indicators and preterm birth in Mexican pregnant women.
Purpose of the Study:
- To explore the association between various oral health indicators and the incidence of preterm delivery.
- To identify specific oral health issues that may increase the risk of preterm birth among pregnant women.
- To provide evidence supporting the importance of oral health interventions during prenatal care.
Main Methods:
- A case-control study involving 111 pregnant women (36 cases, 75 controls) in Pachuca, Mexico.
- Data collected through clinical file reviews, focusing on preterm delivery as the dependent variable.
- Independent variables included gingivitis, periodontitis, DMFT index, decayed teeth, maternal age, education, substance use, parity, and newborn sex.
Main Results:
- No significant age differences were found between cases and controls.
- Significant associations were observed between preterm delivery and gingivitis (p < .01) and periodontitis (p < .001).
- Increased severity of gingivitis and periodontitis correlated with a higher percentage of preterm deliveries. Tooth loss was also significantly higher in the preterm delivery group (p < .05).
Conclusions:
- Gingivitis, periodontitis, and tooth loss are significantly associated with preterm delivery.
- Interventions to preserve oral health in pregnant patients are essential for preventing adverse pregnancy outcomes.
- Further large-scale, well-designed studies are needed to confirm these associations.
Abstract:
Introduction: Preterm delivery is a multifactorial health problem that represents a serious public health problem around the world. In recent years, there has been an increase in scientific evidence suggesting associations between oral health status (mainly periodontal disease and tooth loss) and an increased risk of systemic diseases and various adverse pregnancy outcomes. This study explores the association between indicators of oral health and preterm delivery in a sample of Mexican pregnant women.Materials and methods: A case-control study was carried out with 111 pregnant (36 cases, 75 controls) who received prenatal care and delivered in an obstetric hospital in Pachuca, Mexico. Clinical files were reviewed to obtain the necessary information for the variables studied. The dependent variable was preterm delivery and the independent variables were gingivitis, periodontitis, DMFT index and its components, the number of decayed teeth with pulpal exposure or endodontic lesions, age of the mother, education, alcohol use, smoking status, number of gestations, and sex of the newborn.Results: The average ages were similar between the cases and the controls (24.29 ± 5.42 versus 24.89 ± 5.67, p = .5781). Significant differences were observed with gingivitis (p < .01) and periodontitis (p < .001). In addition, when the severity of gingivitis or periodontitis increased, the percentage of cases of preterm delivery increased (p < .01). The average number of teeth lost was higher among the cases than among the controls (1.33 ± 1.89 versus 0.81 ± 1.82, p < .05).Conclusions: It was found that gingivitis, periodontitis, and tooth loss were associated with preterm delivery. It is necessary to carry out actions aimed at the preservation of oral health in pregnant patients to avoid adverse results. These findings indicate a likely association, but it needs to be confirmed by large and well-designed studies.
