“…These defects were observed mainly in VLBW children as none of the LBW and normal children were intubated in the neonatal period. A recent Swedish study 21 on full-term infants who were intubated during the neonatal period has further confirmed these findings.…”

Preterm and low birthweight children comprise approximately 6 per cent of all live births. They are prone to many serious medical problems during the neonatal period which may affect the development of oral tissues. The present paper reviews the results of this author's own decade of research into the oral development of preterm children in the light of current understanding of the field. Studies have shown a high prevalence of generalized enamel hypoplasia in the primary dentition of around 40-70 per cent in preterm children which is likely to be associated with low bone mineral stores. The clinical significance of enamel defects is poor aesthetics, and predisposition of the lesions to dental caries. Other dental defects observed in preterm children are localized enamel hypoplasia, crown dilacerations, and palatal distortions which are usually associated with traumatic laryngoscopy and prolonged endotracheal intubation. Furthermore, recent studies have demonstrated that the rate of dental development, and dental eruption may be affected by preterm birth. Children with the lowest birthweight and shortest gestational ages have the lowest rates of dental development, particularly before six years of age. The results of these clinical studies may have significant implications in the dental management of preterm children.

“…The preterm children that had been intubated had more enamel defects in the anterior upper jaw compared with those not intubated. Local trauma at intubation usually results in local enamel defects (14,15).…”

Enamel defects were commoner in preterm children, and post-natal dietary intervention had no effect on their frequency. This is the first study in which enamel defects in both primary and permanent teeth have been studied in the same group of preterm children. At age 1 and 2 yrs, 32 preterm children were examined, and the same group was examined again at 9-11 yrs. As controls, 106 healthy children were examined at 1 and 2 yrs, and 64 of them were randomly selected for comparison. When the preterm children were aged 9-11 yrs, 64 of another group of 150 10-13 yr-olds were randomly chosen as controls. All were examined by the main author. At 2 yrs, 66% of preterm children had enamel hypoplasia, and 2% of controls (P < 0.001); enamel opacity affected respectively 13% and 19% (NS). However, the proportions of teeth thus affected were respectively 16% and 0.1%, and 13% and 4%. In the permanent dentition around 10 yrs later, 38% of preterm children had hypoplasia, and 11% of controls (P < 0.01), and opacity affected respectively 47% and 25% (P < 0.05). All preterm infants had primary dentition enamel defects, and 72% also had permanent dentition defects. The preterm infants had been randomly assigned to 2 levels of vitamin D supplementa-tion up to age 6 months, and to breast milk with or without a supplement of calcium and phosphorus until reaching a weight of 2kg. These supplements had no apparent effect on enamel defects.

“…Hypoplastic areas are reported as being highly susceptible to dental caries 3,9,15 because, through ultrastructural analysis, they have shown enamel with less mineralization, more porosity, with irregular surfaces allowing the accumulation of bacteria which is favorable to the development of colonies of Streptococcus mutans , resulting in carious lesions 3,11,13 .…”

ObjectivesThe aim of this study was to evaluate the prevalence of enamel defects and their risk factors on primary and permanent dentitions of prematurely born children and full-term born children born at Regional Hospital of Asa Sul, Brasília, DF, Brazil.Material and MethodsEighty 5-10-year-old children of both genders were examined, being 40 born prematurely (G1) and 40 born full term (G2). The demographic variables, medical history and oral health behaviors were retrieved using a questionnaire and data obtained from clinical examination were recorded. The teeth were examined and the presence of enamel defects was diagnosed according to the DDE Index and registered in odontograms. Subsequently, the defects were categorized in four groups according to one of the criteria proposed in 1992 by the FDI Commission on Oral Health, Research and Epidemiology. Kruskal-Wallis, Chi-square, Kappa, Mann-Whitney tests and logistic regression were used for statistical analysis.Results75% of total sample had enamel defects. There was a major prevalence of hypoplasia of the enamel in G1 (p<0.001). There was a significant relationship between low weight and presence of the imperfections on the enamel in G1 on the primary dentition. The logistic regression model showed that the other risk factors such as monthly per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases were not associated with enamel defects and caries.ConclusionsPre-term labor can be a predisposing factor for the presence of the enamel hypoplasia in the primary dentition.
