- Abstract
Objective: The etiology of hypomineralized second primary molar (HSPM) appears to be multifactorial but remains uncertain. Thus, the objective was to systematically review studies that investigated adverse health conditions in the prenatal, perinatal and postnatal periods associated with HSPM. Material and methods: The search was carried out in five databases and in gray literature. The risk of bias of observational studies was analyzed according to the Newcastle–Ottawa scale. Results: A total of 1878 studies were identified. Fourteen were eligible, and seven were included in the meta-analysis. Maternal smoking (OR = 2.88; 95%CI: 1.62–5.15) and presence of maternal hypertension (OR = 2.91; 95%CI: 1.35–6.28) were significantly associated with higher odds of HSPM. In the perinatal period, factors associated with HSPM were low birth weight (OR = 1.50; 95%CI: 1.15–1.96), prematurity (OR = 1.93; 95%CI: 1.37–2.71), delivery complications (OR = 2.42; 95%CI: 1.52–3.83) and need for an incubator (OR = 1.65; 95%CI: 1.01–2.70). Not breastfeeding (OR = 1.26; 95%CI: 1.01–1.58), use of antibiotics by the child (OR = 1.24; 95%CI: 1.04–1.48), fever (OR = 1.37; 95%CI: 1.10–1.72) and asthma (OR = 1.91; 95%CI: 1.16–3.13) were the postnatal factors associated with HSPM. Conclusion: Maternal smoking, maternal hypertension, low birth weight, prematurity, delivery complications, need for incubation, not breastfeeding, antibiotic use, fever and childhood asthma were associated with HSPM. Well-designed prospective cohort studies are needed. Clinical relevance Understanding the etiological factors can be guiding aspects for individual clinical approaches, as well as guiding the design of preventive interventions for HSPM.
