Prevalence of dental enamel defects in celiac patients with deciduous dentition: a pilot study

Coeliac disease and its implications on the oral health of children: A systematic review

AIM

Apart from various typical gastrointestinal symptoms, coeliac disease may have its clinical manifestations in the oral cavity which is the entrance of the gastrointestinal tract.

METHODS

A systematic review of literature was performed using the following databases: Medline, Scopus, EBSCOhost and Cochrane Library for Systematic Review.

INCLUSION CRITERIA

observational or experimental original studies published in English with full text available between January 2000 and December 2022, regarding children and adolescents under the age of 20. Risk of bias was determined with the use of Risk Of Bias In Non-randomised Studies of Exposure.

RESULTS

Thirty-four studies were included in the review. The analysis confirmed a higher prevalence of numerous oral manifestations in coeliac disease concerning both hard and soft tissues. Our study found the prevalence of dental enamel defects to be at the level of 17.9%-83.5% (P value <0.047) and recurrent aphthous stomatitis of 8.3%-69% (P value <0.039).

CONCLUSION

Oral manifestations may precede gastrointestinal symptoms. Patients presenting such manifestations should be screened for coeliac disease. The cooperation of gastroenterologists and dentists could lead to an increased detectability of coeliac disease.

Nutrition and oral health in children with recently and previously diagnosed celiac disease

OBJECTIVES

To evaluate the nutritional and oral health status of children with previously diagnosed celiac disease (CD) who follow a gluten-free diet and recently diagnosed CD patients.

MATERIALS AND METHODS

Previously and recently diagnosed groups were formed from children with CD, aged 4 to 15 years. A questionnaire was completed about the children's dental history and nutritional and oral hygiene habits. All the children underwent an oral examination, and dmft-DMFT indices were determined. Dental plaque status, periodontal health, and dental enamel defects were recorded. Oral soft tissues were examined for the presence of lesions. Unstimulated salivary flow rate and pH value were evaluated.

RESULTS

A statistically significant difference was determined between the previously and recently diagnosed patients in terms of toothpaste preference (p=0.003), frequency of going to the dentist (p=0.039), and the types of dental treatment they had received (p=0.001). A statistically significant difference was determined between the previously and recently diagnosed patient groups in terms of dmft values (p=0.005).

CONCLUSIONS

Children with CD should be directed to a pediatric dentist to improve oral and dental health, relieve the symptoms of oral mucosal lesions, be informed about enamel defects, and be encouraged to use gluten-free oral care products.

CLINICAL RELEVANCE

The collaboration of pediatric gastroenterologists and pediatric dentists can prevent the progression of oral symptoms in children with CD and eliminate long-term complications in terms of both oral health and multisystemic problems.

Serological study of celiac disease in children with dental caries

BACKGROUND

Celiac disease is a common gastrointestinal autoimmune disorder. Studies have shown that the prevalence of tooth decay is high in patients with celiac disease. This study was performed to evaluate the serology of celiac disease in children with dental caries.

METHODS

Children aged 3 to 12 years who referred to the dental clinic with enamel caries were included in the study. Celiac disease was assessed by measuring serum IgA levels and anti-TTG (Anti TTG (IgA)) antibodies. Then, by analyzing the collected data, the prevalence of celiac disease in children with dental caries and its relationship with various variables were investigated.

RESULTS

120 children, 56 girls (46.7%) and 64 boys (53.3%) with dental caries were involved in this study. The positive celiac serology rate of studied population was 14 (11.6%). Based on the results of this study, a significant relationship was obtained between maternal education, sex and place of residence and celiac disease (p< 0.05). There were no significant relationships between celiac positive serology in children with dental caries, the number of decayed teeth, and breastfeeding (p> 0.05).

CONCLUSION

The present study showed that dental caries, might be a red flag indicating possible celiac disease and prevent its complications. On the other hand, pediatricians and dentists should be aware of the oral symptoms of celiac disease. Further studies are needed to plan screening for children with celiac disease.

Oral Health Impact Profile in Celiac Patients: Analysis of Recent Findings in a Literature Review

The increment of recording atypical oral manifestation in young patients often related to systematic disease is today a challenge for the therapists. Sometime, the presence of tooth enamel lesions correlated with soft tissue lesions is just a symptom or a trigger sign for a deeper and undetermined disease. Recently, high impact has been developed toward the influence of the diet as a controlled and modifiable factor in patients affected by celiac pathologies. The celiac disease (CD) is a chronic immune-mediated disorder triggered by the ingestion of gluten that appears in genetically predisposed patients. Gluten is a proline-rich and glutamine-rich protein present in wheat (gliadin), barley (hordein), and rye (secalin). The gluten-free diet (GFD) seems to better influence the oral health status of the CD patients. For this reason, the main objective of this revision was to analyze the international data highlighting the relationship between celiac patients and the oral health impact profile. A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed database. Authors conducted the search of articles in the English language published from 2008 to 2018. The first analysis with filters recorded 67 manuscripts accordingly with the selected keywords. Finally, a number of 16 appropriate published papers were comprehended in the review. The studies were different in terms of the structure, findings, outcomes, and diet quality evaluation, and for this reason, it was not possible to accomplish a meta-analysis of the recorded data. This manuscript offers some observational evidence to justify the advantages of gluten-free diets related to a better oral health status in the patients involved.

Clinical evaluation of dental enamel defects and oral findings in coeliac children

Purpose

To examine dental hard and soft tissue changes of coeliac children in order to increase the awareness of the pediatric dentists in prediagnosis of especially undiagnosed coeliac disease.

Materials and methods

Sixty children, 28 (46.7%) boys and 32 (53.3%) girls whose ages were between 6 to 16 years were included in the present study. Thirty children who had undergone endoscopy and diagnosed with the coeliac disease in the Şişli Hamidiye Etfal Hospital, İstanbul, Turkey, formed the study group. Also, thirty children clinically suspected of having the coeliac disease with the same gastrointestinal complaints had undergone endoscopy and proven not coeliac were chosen as the control group. Oral examination involved assessment of dentition and specific and unspecific dental enamel defects. Also, soft tissue lesions, clinical delay of the dental eruption, salivary flow rate, pH, and buffering capacity were examined.

Results

Twenty coeliac patients had enamel defects, however none in the control subjects. In the coeliac group, all enamel defects were diagnosed in permanent teeth and as specific in all children. Grade I dental enamel defects found mainly in the incisors. The clinical delayed eruption was observed in 10 (33.3%) of 30 coeliac children and none of the children in the control group. While the level of DMFT/S numbers and stimulated salivary flow rate were found significantly lower in the coeliac group, pH was found significantly higher.

Conclusion

Oral cavity may be involved in coeliac disease and pediatric dentists can play an important role in the early diagnosis of the coeliac disease.

Association between developmental defects of enamel and celiac disease: A meta-analysis

OBJECTIVES

Studies have observed the presence of extra-intestinal manifestations of celiac disease (CD), including involvement of the oral cavity, such that developmental defects of enamel (DDE) occur. Thus, the aim of this review was to access the polled prevalence of DDE in individuals with CD, and to establish the strength of the association between these two variables.

METHODS

To carry out the systematic review, four electronic databases and the Grey Literature were searched, complemented by a manual search of reference lists within the selected articles. Two pairs of independent reviewers selected the articles, and perform the data extractions and bias risk assessment Studies evaluating the presence of DDE in individuals with CD as well as in healthy individuals and which performed the DDE diagnosis by direct visualization of tooth enamel changes and the CD diagnosis were included. Meta-analyses were performed using the software R.

RESULTS

Of 557 studies, 45 were selected for review, encompassing 2840 patients. The prevalence of DDE in people with CD was 50% (95% CI 0.44-0.57, I² = 88%). In a general analysis, it was observed that patients with CD had a significantly higher prevalence of enamel defects compared to healthy people (RR: 2.31, 95% CI: 1.71-3.12, I² = 98%). Only developmental defects of enamel diagnosed using Aine's method were associated with the disease (RR: 3.30, 95% CI 2.39-4.56, I² = 75%). In a sensitivity analysis involving the deciduous, mixed and permanent dentitions, only individuals with deciduous dentition were observed to have association with the disease (RR: 2.34, 95% CI 1.25-4.39, I² = 39%).

CONCLUSIONS

Patients with enamel developmental defects should be screened for the possibility of their having celiac disease.

Tooth Wear Is Frequent in Adult Patients with Celiac Disease

(1) Background: Celiac disease (CD) patients can be affected by mouth and tooth disorders, which are influenced by their gluten-free diet. The aim of our research was to evaluate the pathological conditions of the stomatognathic system observed in celiac patients on a gluten-free diet. (2) Methods: we consecutively recruited celiac patients on a gluten-free diet at our celiac center, as well as healthy volunteers. Two dentists examined all patients/controls and checked them for any mouth disorder. (3) Results: Forty-nine patients affected by celiac disease (age at test 31.8 ± 11.58, time on GFD 8.73 ± 7.7) and 51 healthy volunteers (age at test 30.5 ± 8.7) were included. Recurrent aphthous stomatitis was reported in 26 patients (53.0%) and in 13 (25.5%) controls (p = 0.005). Dental enamel disorders were reported in 7 patients (14.3%) and in 0 controls (p = 0.002), with none having geographic tongue. We found non-specific tooth wear, characterized by loss of the mineralized tissue of the teeth, in 9 patients (18.3%) and in 3 (5.9%) controls (p = 0.05). (4) Conclusion: Recurrent aphthous stomatitis and enamel hypoplasia are "risk indicators" that may suggest that an individual has CD. We detected a high prevalence of non-specific tooth wear that can be caused by several factors such as malocclusion, sleep bruxism, parafunctional activity, and age.

Generation R birth cohort study shows that specific enamel defects were not associated with elevated serum transglutaminase type 2 antibodies

AIM

Coeliac disease can induce specific enamel defects (SED), but little is known about the consequences of antitissue transglutaminase (TG2A) autoimmunity. We investigated whether TG2A positivity in children and their mothers was associated with SED in the primary dentition.

METHODS

Maternal and child serum immunoglobulin A-TG2A levels were measured as part of the Generation R prospective cohort study. Clinical oral photographs of the primary dentition were taken, and SED and caries were recorded. We performed logistic regression analysis.

RESULTS

We analysed data on 4775 mothers and 4233 children (median age of 6.2 ± 0.5 years). SED and caries were not associated with maternal TG2A levels. The 59 TG2A-positive children tended to have more SED, particularly the 31 in the strongly positive subgroup, with odds ratio of 1.72 and 2.29, respectively. A positive linear trend was observed between higher TG2A levels and paediatric SED (p = 0.04), but this became nonsignificant after adjusting for ethnic and socio-economic background. No difference in caries was found between the groups.

CONCLUSION

TG2A did not play an independent role on SED in the primary dentition during pregnancy and childhood, and the relationship may be explained by ethnic and socio-economic background.

Developmental defects of enamel and dentine: challenges for basic science research and clinical management

Abnormalities of enamel and dentine are caused by a variety of interacting factors ranging from genetic defects to environmental insults. The genetic changes associated with some types of enamel and dentine defects have been mapped, and many environmental influences, including medical illnesses that can damage enamel and dentine have been identified. Developmental enamel defects may present as enamel hypoplasia or hypomineralization while dentine defects frequently demonstrate aberrant calcifications and abnormalities of the dentine-pulp complex. Clinically, developmental enamel defects often present with problems of discolouration and aesthetics, tooth sensitivity, and susceptibility to caries, wear and erosion. In contrast, dentine defects are a risk for endodontic complications resulting from dentine hypomineralization and pulpal abnormalities. The main goals of managing developmental abnormalities of enamel and dentine are early diagnosis and improvement of appearance and function by preserving the dentition and preventing complications. However, despite major advances in scientific knowledge regarding the causes of enamel and dentine defects, further research is required in order to translate the knowledge gained in the basic sciences research to accurate clinical diagnosis and successful treatment of the defects.

Developmental enamel defects in the primary dentition: aetiology and clinical management

Developmental enamel defects, presenting as enamel hypoplasia or opacities are caused by damage or disruption to the developing enamel organ as a result of inherited and acquired systemic conditions. The high prevalence of these defects in the primary dentition demonstrates the vulnerability of the teeth to changes in the pre- and postnatal environment. The presence of enamel hypoplasia increases the risk of primary teeth to early childhood caries and tooth wear as the defective enamel is thinner, more plaque retentive and less resistant to dissolution in acid compared to normal enamel. The purpose of this paper was to critically review the aetiology and clinical complications of developmental enamel defects in the primary dentition and propose recommendations for the clinical management of affected teeth.

Prevalence of enamel defects in primary and permanent teeth in a group of schoolchildren from Granada (Spain)

Objective: The purpose of this study was to determine and compare the prevalence and presentations of developmental defects of the enamel (DDE) in the primary and permanent dentitions of a group of healthy schoolchildren residing in Granada (Spain). Study Design: A total of 1,414 healthy schoolchildren were examined using modified DDE criteria for recording enamel defects. Results: The prevalence of DDE of any type was 40.2% in primary dentition and 52% in permanent dentition (p<0.033). Of the 31,820 primary and permanent teeth examined in the study, 699 (4.1%) primary and 1,232 (8.3%) permanent teeth had some form of DDE. Diffuse opacity was the most common type of DDE observed in primary teeth, and demarcated opacity in the permanent teeth. Enamel hypoplasia was the least prevalent defect in both dentition types. Conclusions: The study population showed a high prevalence of DDE in primary as well as in permanent dentition, reflecting the current increasing trend of this condition, which should be considered as a significant public health problem.

Key words:Developmental enamel defects, enamel hypoplasia, demarcated opacity, diffuse opacity.

Screening for celiac disease in children with dental enamel defects

Background. Dental enamel defects (DEDs) are seen in celiac disease (CD). Aim was to detect frequency of CD among such patients. Methods. This study included 140 children with DED. They were tested for CD. Gluten-free diet (GFD) was instituted for CD patients. A cohort of 720, age and sex-matched, normal children represented a control group. Both groups were evaluated clinically. Serum calcium, phosphorus, alkaline phosphatase, serum IgA, and tissue transglutaminase (tTG) IgG and IgA types were measured. Results. CD was more diagnosed in patients with DEDs (17.86%) compared to controls (0.97%) (P < 0.0001). Majority of nonceliac patients showed grade 1 DED compared to grades 1, 2, and 3 DED in CD. Five children had DED of deciduous teeth and remaining in permanent ones. After 1 year on GFD, DED improved better in CD compared to nonceliac patients. Gastrointestinal symptoms did not vary between celiac and nonceliac DED patients. Lower serum calcium significantly predicted CD in this cohort. Conclusion. CD is more prevalent among children with DED than in the general population. These DEDs might be the only manifestation of CD; therefore, screening for CD is highly recommended among those patients especially in presence of underweight and hypocalcemia.

Oral findings and salivary parameters in children with celiac disease: a preliminary study

OBJECTIVE

The aim of this study was to investigate the prevalence of dental enamel defects, recurrent aphthous stomatitis (RAS) and caries experience and to measure salivary flow rate, buffer capacity, saliva and plaque pH and salivary cariogenic microflora in patients with celiac disease (CD) compared to healthy subjects.

SUBJECTS AND METHODS

Thirty-five patients, aged 6-19 years, with a diagnosis of CD and 35 healthy children of the same age participated in the study. Enamel defects were diagnosed and classified using Aine's classification. The patients with RAS and dental caries were recorded using WHO criteria. The parents were interviewed about various oral health-related factors. Saliva samples were collected to measure the stimulated salivary flow rate, buffer capacity and pH values of saliva and plaque. Salivary mutans streptococci and lactobacilli were counted.

RESULTS

The enamel defects and RAS prevalence were statistically higher (40 and 37.1%, respectively) in the CD group, and the prevalence of salivary mutans streptococci (48 and 14%) and lactobacilli (51 and 34%) colonization was statistically lower (p = 0.012, p = 0.010) in the CD group; the DMFS and dfs values were similar in both groups.

CONCLUSION

CD appeared to be associated with a significantly higher prevalence of developing enamel defects and RAS, but a lower prevalence of salivary mutans streptococci and lactobacilli colonization, and the diagnosis of these oral manifestations might be helpful for an early diagnosis of CD.

Implications of gluten exposure period, CD clinical forms, and HLA typing in the association between celiac disease and dental enamel defects in children. A case-control study

BACKGROUND

The association between coeliac disease (CD) and dental enamel defects (DED) is well known.

AIM

The aim of this study was to investigate the prevalence of DED in children with CD and to specifically find the association of DED and gluten exposure period, CD clinical forms, HLA class II haplotype.

DESIGN

This study was designed as a matched case-control study: 250 children were enrolled (125 coeliac children - 79 female and 46 male, 7.2 +/- 2.8 years and 125 healthy children). Data about age at CD diagnosis, CD clinical form, and HLA haplotype were recorded.

RESULTS

Dental enamel defects were detected in 58 coeliac subjects (46.4%) against seven (5.6%) controls (P < 0.005). We found an association between DED and gluten exposure period, as among CD subjects the mean age at CD diagnosis was significantly (P = 0.0004) higher in the group with DED (3.41 +/- 1.27) than without DED (1.26 +/- 0.7). DED resulted more frequent (100%) in atypical and silent CD forms than in the typical one (30.93%). The presence of HLA DR 52-53 and DQ7antigens significantly increased the risk of DED (P = 0.0017) in coeliac children.

CONCLUSIONS

Our results confirmed a possible correlation between HLA antigens and DED.

Celiac disease

PURPOSE OF REVIEW

To summarize recent advances in celiac disease published between August 2008 and July 2009.

RECENT FINDINGS

Celiac disease affects nearly 1% of most populations but remains largely unrecognized. In the last year, work has shown that the prevalence of celiac disease has increased dramatically, not simply due to increased detection. Also, undiagnosed celiac disease may be associated with increased mortality. Significant progress has been made in understanding how gliadin peptides can cross the intestinal border and access the immune system. New genetic loci and candidate genes that may contribute to the risk of celiac disease and its overlap with type 1 diabetes mellitus have been identified. Novel deamidated gliadin peptides antibodies have better diagnostic accuracy over native gliadin-based tests. The inclusion of duodenal bulb biopsy specimens may increase the rate of celiac disease detection. The spectrum of celiac disease likely includes a minority of patients with mild enteropathy. A practical seven-item instrument may facilitate standardized evaluation of gluten-free diet adherence. Finally, refractory celiac disease, although rare, is associated with a poor prognosis.

SUMMARY

Celiac disease is a global health problem that requires a multidisciplinary and increasingly cooperative multinational research effort.
