Objective: To evaluate the presence of enamel alterations in deciduous maxillary central incisors of infants with unilateral cleft lip and alveolar ridge, with or without cleft palate, and to compare the occurrence and location of these alterations between the central incisor adjacent to the cleft and the contralateral incisor. Design: Intraoral clinical examination was performed after tooth cleaning and drying by a single examiner with the aid of a dental mirror, dental probe, and artificial light, with the child positioned on a dental chair. The defects were recorded in a standardized manner according to the criteria of the Modified Developmental Defects of Enamel Index. Setting: Hospital for Rehabilitation of Craniofacial Anomalies (HRAC) at Bauru, São Paulo, Brazil. Patients: One hundred one infants were evaluated. All were white, of both genders, aged 12 to 36 months and had at least two thirds of the crowns of maxillary incisors erupted. Results: Demarcated opacity was the most common defect at both cleft and noncleft sides, followed by diffuse opacity. The occurrence of hypoplasia at the cleft side was 11.8%. Most defects affected less than one third of the crown. Conclusion: The occurrence of enamel defects in deciduous maxillary central incisors of patients with unilateral cleft lip was 42.6%, mainly affecting the cleft side as to both number and severity.

Objective This study investigated the prevalence, type, and location of enamel defects in the permanent teeth of patients with complete unilateral or bilateral cleft lip and palate (CLP), and compared the prevalence and characteristics of defects between CLP patients and non-CLP individuals. Methods We examined completely erupted permanent dentition, except for third molars, of CLP patients and non-CLP individuals of both sexes, 9–36 years of age, and analyzed corresponding panoramic radiographs. Two independent examiners performed clinical examinations in accordance with the Modified Developmental Defects of Enamel index. Results A total of 210 (87.9%) CLP patients and 194 (41.4%) non-CLP individuals had at least one enamel defect; these were more prevalent in the CLP group than in the non-CLP group. Upper teeth were primarily affected by enamel defects associated with the cleft; defects were most prevalent on the cleft side in CLP patients, followed by the non-cleft side in CLP patients, and then by non-CLP individuals. Conclusion Enamel defects were more common in CLP patients than in non-CLP individuals. Among CLP patients, enamel defects were more prevalent in the cleft side of the maxilla; the central incisor was the most commonly affected tooth in this quadrant.

OBJECTIVE: This study aimed to evaluate the prevalence of developmental defects of enamel (DDEs) in relation to asthma severity, symptom onset and pharmacological treatment in pediatric asthma patients. METHODS: Children and adolescents (68 asthma patients and 68 controls), 5-15 years of age and residents of the city of Londrina, Brazil, were enrolled in the study. Medical and dental histories were collected through the use of a structured questionnaire. Each participant underwent a dental examination in which the examiner employed the DDE index. RESULTS: Of the 68 asthma group subjects, 61 (89.7%) presented dental enamel defects, compared with only 26 (38.2%) of those in the control group. Using multivariate logistic regression analysis, we estimated the risk of DDEs in permanent dentition to be 11 times higher in pediatric subjects with asthma than in those without (OR = 11.88, p = 0.0001). The occurrence of dental enamel defects correlated with greater asthma severity (p = 0.0001) and earlier symptom onset (p = 0.0001). However, dental enamel defects did not correlate with the initiation of treatment (p = 0.08) or the frequency of medication use (p = 0.93). CONCLUSIONS: Pediatric patients with severe, early-onset asthma are at increased risk of dental enamel defects and therefore require priority dental care.

The FDI (DDE) Index-with some modifications and a re-designed recording sheet-was used to determine the prevalence of the different types of developmental defects of enamel. The public water supply contained 1.0 ppm when the children were born and 0.7 ppm at the time of the examinations. All surfaces of the teeth of 460 female and 484 male, 12-year-old, Chinese children were examined after the teeth had been cleaned and dried. Mouth prevalences for all types of opacities, hypoplasia, and discoloration were 99.6%, 82.8%, and 16.6%, respectively. There was no apparent statistically significant difference between girls and boys. However, a statistically significant difference was seen between the sexes for white patches (p < 0.05), missing enamel (p<0.05), and horizontal grooves (p<0.01). There were 811 (85.7%) children with more than 13 teeth affected by opacities, and 417 (44.2%) children had more than four teeth affected by hypoplasia. The most common defect was the diffuse white patch, and the least common was the vertical groove. There were 189 (39.0%) boys with between four and 12 teeth affected by more than two types of defect per tooth. White lines were the most difficult defect to diagnose reproducibly. Intra-examiner reproducibility for all other defects achieved levels of "almost perfect" and "substantial" by calculation of the Kappa coefficient.

Objective To evaluate the prevalence of enamel alterations affecting the deciduous and permanent central maxillary incisors of children with complete unilateral cleft lip and palate and to verify their characteristics. Design Cross-sectional. Setting Hospital for Rehabilitation of Craniofacial Anomalies–University of São Paulo, Bauru, São Paulo, Brazil. Patients A sample of 90 patients attending the Hospital for Rehabilitation of Craniofacial Anomalies, presenting with complete cleft lip and palate, of both genders, ages 2 to 11 years old. Methodology The buccal surfaces of the maxillary central incisors of patients were analyzed for observation of the presence of enamel defects, their type, number, and location. The prevalence of defects was compared between deciduous and permanent teeth and between the incisors at the cleft and noncleft sides. Results There was a higher frequency of defects among incisors on the cleft side for both deciduous and permanent dentitions compared with the noncleft side (p < .05); the permanent central incisor was more frequently affected than the deciduous. Evaluation of the types of defects for both incisors in both dentitions demonstrated a homogeneous distribution, except for a lower proportion of yellow opacity in the permanent dentition on the cleft side. In general, the most affected area in all dentitions was the incisal third. Conclusion The prevalence of enamel alterations affecting incisors adjacent to the cleft was higher than for incisors on the noncleft side. This difference also was present in the permanent dentition.

Developmental Defects Of Enamel

Data concerning the prevalence of developmental enamel defects and their association with dental caries in individuals with intellectual disability are scarce. This paper aims to evaluate the prevalence and distribution of developmental enamel defects and dental caries in the permanent dentition of special-care school children from Poznan (Poland). Out of 1091 students attending all special-care schools in the city, the study covered 268 subjects with intellectual disability (mild, moderate, severe, and profound) with permanent dentition, aged 10–20. One calibrated dentist performed dental examinations. The Statistica Software v10 was used for statistical analysis, assuming the level of statistical significance p ≤ 0.05. Among the subjects of the study, 19.40% presented developmental enamel defects. The number of teeth with changes ranged from 1 to 28, with maxillary incisors most frequently affected. Students without developmental enamel defects had more teeth observed with active caries compared to those with such changes (10.92% vs. 7.82%, p < 0.01). The highest number of students with developmental defects of enamel was observed in the group of individuals with mild intellectual disabilities. The present study revealed that in special-care students from Poznan, enamel defects and dental caries were frequently observed. However, individuals with developmental enamel defects did not show higher dental caries indices.

Objective: This study estimated the prevalence, extent, buccal distribution and associated factors involving enamel defects in Brazilian schoolchildren. Study design: A cross-sectional study using a multistage cluster random sample of 1,206 8–12-year-old Brazilian schoolchildren was carried out in Pelotas, Brazil. The prevalence of enamel defects in the permanent dentition was determined using the modified Developmental Defects of Enamel index (DDE). Sociodemographic and health data were collected from their mothers using a semi-structured questionnaire. Data were analyzed using Poisson regression modelling for DDE prevalence and negative binomial regression modelling for the extent of DDE. Results: The prevalence of any enamel defects was 64.0% (95% Confidence Interval: 61.4, 67.0); the main types were diffuse opacities (35.0%), demarcated opacities (29.5%) and hypoplasia (3.7%). In general, older children had a lower prevalence and extent of enamel defects than their counterparts (p&lt;0.001). There were no other significant associations. Conclusion: Enamel defects are common, especially among younger children, but the role of pre-, peri- and postnatal exposures remains unclear.

Developmental Defects Of Enamel

There has been considerable research focussed on the occurrence and aetiology of developmental defects of enamel, but less is known about the extent to which enamel-defect-affected teeth may be at greater risk for dental caries. The Dunedin Multidisciplinary Health and Development Study is a prospective cohort study of 1,037 children born in Dunedin, New Zealand, between April 1, 1972, and March 31, 1973. Participants were examined for the presence of developmental defects of enamel at the age of 9 years and then repeatedly for the occurrence of dental caries through to the age of 45 years. After controlling for confounding variables, incisor teeth affected by demarcated opacities at the age of 9 were 3.4 times more likely to be restored than teeth unaffected by defects. Incisors with diffuse opacities and hypoplasia or combinations of defects were 2.8 times more likely to be restored. Molars with enamel defects of any type did not have any significantly different risk for being subsequently restored or lost due to caries than unaffected molars, except those affected by diffuse opacities, which were at 0.4 times the risk of being lost due to caries. Dental clinicians should be aware that enamel-defect-affected teeth are not necessarily at greater risk for tooth loss due to caries in the long term, but permanent incisors affected by enamel defects are at higher risk of receiving restorative intervention.

Objective To evaluate the prevalence and type of enamel hypoplasia in deciduous canines of patients with complete unilateral and bilateral cleft lip and palate, as well as its distribution according to gender, dental arch, and side of cleft. Design Cross sectional. Setting Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, São Paulo, Brazil. Material and Methods Three-hundred twelve Caucasian children (193 boys, 119 girls), aged 3 to 10 years, presenting complete unilateral and bilateral cleft lip and palate were included in this study. A single examiner carried out clinical examination under natural light with a dental probe and dental mirror and, after drying of the tooth, by means of a simplified hypoplasia index. Results A prevalence of 43.8% was observed for unilateral and 39% for bilateral clefts. Both groups revealed similar distributions regarding the maxillary and mandibular dental arches and gender. Similar distribution was also observed on the cleft and noncleft sides for the unilateral cleft group. The most frequent type and severity was obvious hypoplasia, followed by minimal hypoplasia, both roughly round. Conclusion The results suggest that the cleft does not influence the occurrence of hypoplasia in deciduous canines.

The purpose of this review was formulated with an aim to understand the prevalence of enamel defects among ID children. An identical search was performed in PubMed, Google scholar, and Cochrane review and was limited to human studies and studies written in English. Reviews, case studies, and case series were excluded from the study. A total of 56 articles were identified. In PubMed 18 articles, Google scholar 29 articles and Cochrane review nine articles were found, respectively. In this, two studies (n = 2), dealt with the developmental defects of enamel with intellectual disability (ID)/mental retardation. This systematic review suggests that developmental defects of enamel was more common in ID children than normal children. A larger number of well designed studies are, however, needed to increase the validity of the studies.

Developmental Defects Of Enamel

The presence of carious lesions in children associated with developmental defects of enamel is frequently observed. Restoring these affected teeth can be a challenge for the clinician. Teeth with enamel defects may have poor or limited resin adhesion and some may require repeated restoration. Prefabricated zirconia permanent molar crowns were recently introduced as an option for restoring severely decayed and broken down young permanent molars. These new restorations offer an efficient, esthetic, and economic option to restore severely broken down carious permanent molars that may be associated with enamel defects in partially or fully erupted molars. A clinical case of a 13-year-old female patient is presented. She had a mandibular second permanent molar that demonstrated significant caries and loss of much of the clinical crown, which was treated with a vital pulpotomy and restored with a prefabricated zirconia crown.
