Summary of "Risk of Dental Caries in Primary Teeth with Developmental Defects of Enamel: A Longitudinal Study with a Multilevel Approach."

The risk of dental caries seems to be greater in the presence of developmental defects of enamel (DDE). The aim was to determine whether the presence of DDE in the primary teeth of preschool children increases the risk of dental caries in the primary dentition after a period of approximately 2 years. This study was conducted in two stages: baseline (T0) and follow-up (T1). At T0, examinations were conducted for the diagnosis of enamel defects using the DDE index (FDI, 1992), dental caries, and oral hygiene. The participants were allocated to two groups according to the presence (affected) or absence (unaffected) of DDE. At the second evaluation (T1), examinations were performed for the diagnosis of dental caries. Poisson regression analysis with a multilevel approach was used to determine the association between DDE and dental caries. The two levels of the analysis were tooth and child. Among the 339 children (113 affected and 226 unaffected) examined at baseline (T0), 325 were re-examined at follow-up (T1). According to the multilevel analysis, teeth with enamel hypoplasia had a greater risk of having dental caries (
1.99; 95%
1.19-3.33). The risk of caries was greater on posterior teeth (
2.59; 95%
2.18-3.07) and maxillary teeth (
1.48; 95%
1.26-1.75) that had DDE at T0. On the child level, dental caries at T1 was associated with having dental caries at T0 (
1.38; 95%
1.32-1.46). In conclusion, enamel hypoplasia and previous dental caries are risk factors for carious lesions in the primary dentition.

A film that attaches to teeth, often causing DENTAL CARIES and GINGIVITIS. It is composed of MUCINS, secreted from salivary glands, and microorganisms.

The predisposition to tooth decay (DENTAL CARIES).

Treatment for the prevention of periodontal diseases or other dental diseases by the cleaning of the teeth in the dental office using the procedures of DENTAL SCALING and DENTAL POLISHING. The treatment may include plaque detection, removal of supra- and subgingival plaque and calculus, application of caries-preventing agents, checking of restorations and prostheses and correcting overhanging margins and proximal contours of restorations, and checking for signs of food impaction.
