“…The incidence of DDE found in our VLBW infants was lower compared with the prevalence rates found in previous literature (Johnsen et al, 1984;Seow et al, 1989;Lai et al, 1997;Aine et al, 2000;Takaoka et al, 2011). First, our study infants were younger (< 2yrs) than in previous studies; thus, the entire primary dentition was not present; Second, our rates may also be underestimated due to cooperation issues (moving, crying) when young infants are being examined.…”

“…Prevalence estimates for DDE in diverse populations of very low birthweight children (VLBW) range between 52 and 96% (Johnsen et al, 1984;Seow et al, 1989;Lai et al, 1997;Aine et al, 2000;Takaoka et al, 2011). VLBW occurs most frequently with pre-term birth, and disproportionately among African Americans and those of lower socio-economic status (Hamilton et al, 2012).…”

Birth cohort studies of developmental defects of enamel (DDE) and early childhood caries (ECC) in very low birthweight (VLBW) and normal birthweight (NBW) infants are rare. In this birth cohort of 234 VLBW and 234 NBW infants, we report the incidence of ECC and DDE at 8 and 18-20 mos of corrected age. Infant medical and maternal socio-demographic data were abstracted from medical records at birth. Dental assessments for ECC and DDE (enamel hypoplasia, demarcated and diffuse opacities) were completed at 8 and 18-20 mos. The incidence of hypoplasia was significantly higher in VLBW compared with NBW infants (8 mos, 19% vs. 2%; 18 mos, 31% vs. 8%). The incidence of ECC (International Caries Detection and Assessment System: ICDAS ≥ 2) was 1.4% (8 mos) and 12% (18-20 mos) and was similar between the VLBW and NBW groups. At both ages, using a beta-binomial regression model to control for potential confounders (maternal and infant characteristics), we found increased risk for enamel hypoplasia among the VLBW infants compared with the NBW infants. African Americans had a lower risk for enamel hypoplasia at 18-20 mos. The VLBW infants should be monitored for ECC due to the presence of enamel hypoplasia.

“…It is possible that the small number of cases (n = 14) may have contributed to the lack of association of variable throat infection and cases of MIH. Another study showed association between infection in the upper respiratory tract and MIH in a sample using 22 cases of MIH [25].…”

Objective: To determine the prevalence of molar-incisor hypomineralization (MIH) in the permanent dentition and assess the factors associated with these change in schoolchildren of São Luís, Brazil. Material and Methods: Overall, 1179 students aged 7-14 years of both sexes were included, all with permanent first molars and incisors erupted in the oral cavity. Oral clinical examination to assess the prevalence of HMI was held at school, under natural light. In the second stage, to assess factors associated with HMI, a case-control study was conducted, in which cases were children diagnosed with HMI (n = 14) and as controls, the schoolchild's brother (family control, n = 10 ) and another schoolchild in the same age group born in the same locality (community control, n = 14). A semistructured questionnaire was completed by mothers to identify possible factors associated with HMI, such as maternal education, family income, data from pregnancy and child's medical history in the first three years of life. Logistic regression analysis was used to estimate odds ratios (Odds Ratio -OR) and their confidence intervals at 95% (CI 95%) to assess crude and adjusted associations for confounders. Results: A prevalence of 2.5% of HMI was estimated. No association was found for the etiologic factors surveyed. Conclusion: The prevalence of HMI was lower than that reported in other cities in Brazil, but similar to data from other countries. At the difficulty and complexity in establishing the etiologic factors of HMI, cohort studies are required to clarify this change.

“…These studies showed a prevalence ranging from 26% to 96% DDE. Many of these studies showed the tracheal intubation as an important risk factor in the determination of DDE in deciduous teeth of children born preterm 11,22,[24][25][26] . The birth of a premature child corresponds in odontogenesis to the late bell stage, time in which the deciduous teeth are in the stage of mineralization of the organic matrix of tooth enamel.…”

“…The explanation lies in the fact that the maxillary central incisor teeth of premature infants present a reduced percentage of mineralization in the organic matrix at birth 31 . In these teeth neonatal line lies between the incisal edge and the middle line of the crown 24 . However, when gestational age is corrected, the delay in the eruption is not observed 32,33 .…”

Aim. This study aimed to evaluate the relationship between intubation during the neonatal period and enamel defects in primary teeth of preterm infants. It was an observational, prospective, analytical and sampling of convenience. We selected 157 children who had average birth weight of 1656.3 ± 627.8 g, gestational age of 31.7 ± 2.7 weeks and the examination of chronological age 2.2 ± 0.6 years old. Methods. Clinical examination of the oral cavity showed that the frequency of enamel defects was higher (86.3%) among children intubated when compared to non-intubated children (13.7%). The enamel defects was found to be inversely proportional to gestational age. The intubation time was related to the probability of occurrence of DDE (P<0.001), in other words, the greater the number of days intubated, the greater the chance of DDE. In children intubated, hypoplasia mainly affected the upper teeth on the left side of the mouth. Conclusion. Tracheal intubation in the neonatal period is the main cause of enamel defects in primary teeth of children born preterm. The longer the duration of intubation, the greater the chance of developing dental enamel defect. The area of action during movement of the laryngoscope toggle corresponds to the region most affected by tooth enamel hypoplasia in children intubated, upper right central incisor, lateral incisor and upper left.
