Oral and dental manifestations of celiac disease in children: a case-control study

Importance of celiac disease oral manifestations in pediatric patients: A systematic review

BACKGROUND

Celiac disease (CD) is an autoimmune disease triggered by the ingestion of gluten in genetically predisposed individuals. It is more commonly diagnosed in children presenting typical clinical signs and symptoms but most of the CD patients diagnosed in the developed world are silent cases with no prominent gastrointestinal features. Thus, there are silent forms of the disease in which oral manifestations are the first sign. In the pediatric population oral health can affect growth and self-esteem and have a negative impact in their life quality.

AIM

To assess the prevalence and types of oral manifestations in pediatric patients with CD.

METHODS

We performed a comprehensive literature search in PubMed, Scielo, Cochrane Library and Lilacs databases from 2014-2024. Three independent researchers screened and extracted the information, applying the eligibility criteria and bias was assessed using Joanna Briggs Institute tools.

RESULTS

Of the initial 241 articles, 14 studies fulfilled the proposed objectives and were included in the review. The main oral manifestations found were recurrent aphthous stomatitis and enamel defects. Additionally, delayed tooth eruption, angular cheilitis, glossodynia and xerostomia were also reported.

CONCLUSION

Assessing oral manifestations is crucial, especially in underdiagnosed cases of children with CD. Recognizing these signs helps pediatricians or general practitioners identify them during routine exams, enabling early diagnosis and treatment to prevent negative impacts on the child’s and family’s quality of life.

Associations between Celiac Disease, Extra-Gastrointestinal Manifestations, and Gluten-Free Diet: A Narrative Overview

Millions of children and adults worldwide suffer from undiagnosed and untreated celiac disease (CeD). The clinical picture of CeD is highly heterogeneous and comprises manifestations that can affect almost the whole body. This narrative overview is aimed at characterizing diseases and complaints that are associated with unrecognized CeD and that frequently involve sites other than the gastrointestinal (G.I.) tract, i.e., dental, otorhinolaryngological, and ocular complications; skin and hair abnormalities; afflictions of the bones, joints, and muscles; cardiovascular affectations; kidney diseases; neuro-psychiatric disorders; and gynecological-obstetrical manifestations. The association between CeD and extra-GI manifestations is frequently overlooked, which leads to a delay in diagnosis. Most CeD-mediated disorders can be treated with a strict gluten-free diet (GFD), but some of them are irreversible unless CeD is diagnosed in time. Some manifestations can be classified as risk factors for CeD, and CeD screening tests for affected patients should be selectively considered. Apart from gastroenterologists, specialists in other medical disciplines can play an important role in identifying people with unrecognized CeD and may help prevent its progress and long-term complications. Further comprehensive investigations are necessary to clarify the pathogenesis of extra-GI manifestations and the effect of a GFD.

Evaluation of children's oral diagnosis and treatment using imaging examination using AI based Internet of Things

BACKGROUND

Although cone beam computed tomography (CBCT) plays an important role in the diagnosis and treatment of oral diseases, its image segmentation method needs to be further improved, and there are still objections about the clinical application effect of general anesthesia (GA) on children's dental fear (CDF).

OBJECTIVE

This study aimed to investigate the application value of CBCT based on intelligent computer segmentation model in oral diagnosis and treatment of children in the context of biomedical signals, and to analyze the alleviating effect of GA on CDF.

METHODS

Based on the regional level set (CV) algorithm, the local binary fitting (LBF) model was introduced to optimize it, and the tooth CBCT image segmentation model CV-LBF was established to compare the segmentation accuracy (SA), maximum symmetric surface distance (MSSD), average symmetric surface distance (ASSD), over segmentation rate (OR), and under segmentation rate (UR) between these model and other algorithms. 82 children with CDF were divided into general anesthesia group (GAG) (n= 38) and controls (n= 44) according to the voluntary principle of their families. Children in GAG were treated with GA and controls with protective fixed intervention. Children's fear survey schedule-dental subscale (CFSS-DS) and Venham scores were counted before intervention in the two groups. CFSS-DS scores were recorded at 2 hours after intervention and after recovery in children in GAG. CFSS-DS and Venham scores were performed in all children 1 week after surgery.

RESULTS

The results showed that the S⁢A value of CV-LBF algorithm was higher than that of region growing algorithm (P< 0.05). OR, UR, MSSD, and ASSD values of CV-LBF algorithm were evidently lower than those of other algorithms (P< 0.05). CFSS-DS scores were lower in GAG than in controls 2 hours after intervention and at return visits after 1 week of intervention (P< 0.001), and Venham scores were lower in GAG than in controls after intervention (P< 0.001). After intervention, the proportion of children with Venham grade 0, 1, 2, and 3 was obviously higher in GAG than in controls (P< 0.001), while the proportion of children with Venham grade 4 and 5 was clearly higher in controls than in GAG (P< 0.001).

CONCLUSION

The results revealed that the computer intelligent segmentation model CV-LBF has potential application value in CBCT image segmentation of children's teeth, and GA can effectively alleviate anxiety of children with CDF and can be used as biomedical signals.

Prediction model of dental caries in 12-year-old children in Sichuan Province based on machine learning

OBJECTIVES

The machine learning algorithm was used to construct a prediction model of children's dental caries to determine the risk factors of dental caries in children and put forward targeted measures and policy suggestions to improve children's oral health.

METHODS

Stratified cluster random sampling was adopted in this study. In accordance with different policies and measures in Sichuan Province, 12-year-old students from 3-4 middle schools in eight cities of Sichuan Province were randomly selected for questionnaire survey, oral examination, and physical examination. Multivariate logistic regression analysis of risk factors for dental caries in 12-year-old children was conducted. The dataset was randomly divided into training set and validation set at a ratio of 7∶3. Four machine learning algorithms, including random forest, decision tree, extreme gradient boosting (XGBoost), and Logistic regression, were constructed using R version 4.1.1, and the prediction effects of the four prediction models were evaluated using the area under receiver operating characteristic curve (AUC).

RESULTS

A total of 4 439 children aged 12 years were included in this study. The incidence of permanent teeth caries was 50.93%. The results of multivariate logistic regression analysis showed that body mass index, highest educational background of the father, highest educational background of the mother, whether to brush teeth, how many times a day, use of toothpaste when brushing teeth, duration of brushing teeth, mouthwash after meals, eating before going to bed after brushing teeth, sweet drinks, snacks, going to dental clinic to examine teeth, and age of brushing teeth were the factors influencing children's dental caries (P<0.05). The AUC values predicted by random forest, decision tree, Logistic regression, and XGBoost were 0.840, 0.755, 0.799, and 0.794, respectively. In the random forest model, the variable with the highest contribution was eating before bed after brushing.

CONCLUSIONS

A prediction model of dental caries in children was established on the basis of random forest, showing good prediction effect. Taking preventive measures for the main factors affecting the occurrence of dental caries in children is beneficial.

Otorhinolaryngological Manifestations and Esophageal Disorders in Celiac Disease: A Narrative Review

Celiac disease (CeD) is a chronic gluten-sensitive immune-mediated enteropathy characterized by numerous intestinal and extra-intestinal signs and symptoms. Among extra-intestinal manifestations, otorhinolaryngological (ORL) complaints in CeD are relatively rare and their relation to CeD is frequently overlooked by physicians. Recent studies underlined that the prevalence of recurrent aphthous stomatitis, aphthous ulcers, geographic tongue, and xerostomia was significantly increased in CeD patients compared with healthy individuals. However, data about the other oral manifestations of CeD, such as atrophic glossitis, glossodynia, angular cheilitis, and salivary abnormalities, are scanty. Further ORL conditions associated with CeD include sensorineural hearing loss, nasal abnormalities, and obstructive sleep apnea. Moreover, several esophageal disorders such as gastroesophageal reflux disease and eosinophilic esophagitis have been associated with CeD. The pathophysiological link between both ORL and esophageal manifestations and CeD might be further investigated. In addition, also the role of gluten-free diet in improving these conditions is largely unclear. Certainly, otorhinolaryngologists can play an important role in identifying people with unrecognized CeD and may help prevent its long-term complications. The aim of this narrative review is to analyze the latest evidence on the association between CeD and ORL and esophageal manifestations.

Beyond the Gut: A Systematic Review of Oral Manifestations in Celiac Disease

BACKGROUND

Celiac disease (CD) is a chronic immune-mediated gluten-sensitive enteropathy, affecting about 1% of the population. The most common symptoms include diarrhea, abdominal pain, weight loss, and malabsorption. Extra-intestinal symptoms include oral manifestations. This systematic review aims to catalog and characterize oral manifestations in patients with CD.

METHODS

a systematic literature review among different search engines using PICOS criteria has been performed. The studies included used the following criteria: tissues and anatomical structures of the oral cavity in humans, published in English and available in full text. Review articles and papers published before 1990 were excluded.

RESULTS

209 articles were identified in the initial search. In the end, 33 articles met the selection criteria. The information extracted from the articles was classified based on the type of oral manifestation. Recurrent aphthous stomatitis (34.6%), atrophic glossitis and geographic tongue (15.26%), enamel defects (42.47%), delayed dental eruption (47.34%), xerostomia (38.05%), glossodynia (14.38%), and other manifestations including cheilitis, fissured tongue, periodontal diseases, and oral lichen planus were found in the celiac subjects of the studies analyzed. The quality of articles on the topic should be improved; however, oral manifestations in CD patients are widely described in the literature and could help diagnose celiac disease.

Dental Manifestations and Celiac Disease-An Overview

This review summarizes recent investigations on dental manifestations in celiac disease. Particular attention is paid to delayed dental eruption and maturity, dental enamel defects, molar incisor hypomineralization, dental caries, dental plaque, and periodontitis. Most studies confirmed a higher frequency of delayed dental eruption and maturation in children and dental enamel defects in children and adults with celiac disease compared to healthy individuals. The malabsorption of various micronutrients, especially calcium and vitamin D, as well as immunity, is considered the main cause of these conditions. An early diagnosis of celiac disease and introducing a gluten-free diet might prevent the development of these conditions. Otherwise, the damage has already been established, and it is irreversible. Dentists can play an important role in identifying people who may have unrecognized celiac disease and may help prevent its progress and long-term complications. Investigations on dental caries, plaque, and periodontitis in celiac disease are rare and inconsistent; these complaints need further examination.

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.

New Approach to Addison Disease: Oral Manifestations Due to Endocrine Dysfunction and Comorbidity Burden

This review highlights oral anomalies with major clinical impact in Addison disease (AD), including dental health and dermatologic features, through a dual perspective: pigmentation issues and AD comorbidities with oral manifestations. Affecting 92% of AD patients, cutaneomucosal hyperpigmentation is synchronous with or precedes general manifestations by up to a decade, underlying melanocytic infiltration of the basal epidermal layer; melanophages in the superficial dermis; and, rarely, acanthosis, perivascular lymphocytic infiltrate, and hyperkeratosis. Intraoral pigmentation might be the only sign of AD; thus, early recognition is mandatory, and biopsy is helpful in selected cases. The buccal area is the most affected location; other sites are palatine arches, lips, gums, and tongue. Pigmented oral lesions are patchy or diffuse; mostly asymptomatic; and occasionally accompanied by pain, itchiness, and burn-like lesions. Pigmented lingual patches are isolated or multiple, located on dorsal and lateral areas; fungiform pigmented papillae are also reported in AD individuals. Dermoscopy examination is particularly indicated for fungal etiology; yet, it is not routinely performed. AD’s comorbidity burden includes the cluster of autoimmune polyglandular syndrome (APS) type 1 underlying AIRE gene malfunction. Chronic cutaneomucosal candidiasis (CMC), including oral CMC, represents the first sign of APS1 in 70–80% of cases, displaying autoantibodies against interleukin (IL)-17A, IL-17F ± IL-22, and probably a high mucosal concentration of interferon (IFN)-γ. CMC is prone to systemic candidiasis, representing a procarcinogenic status due to Th17 cell anomalies. In APS1, the first cause of mortality is infections (24%), followed by oral and esophageal cancers (15%). Autoimmune hypoparathyroidism (HyP) is the earliest endocrine element in APS1; a combination of CMC by the age of 5 years and dental enamel hypoplasia (the most frequent dental complication of pediatric HyP) by the age of 15 is an indication for HyP assessment. Children with HyP might experience short dental roots, enamel opacities, hypodontia, and eruption dysfunctions. Copresence of APS-related type 1 diabetes mellitus (DM) enhances the risk of CMC, as well as periodontal disease (PD). Anemia-related mucosal pallor is related to DM, hypothyroidism, hypogonadism, corresponding gastroenterological diseases (Crohn’s disease also presents oral ulceration (OU), mucogingivitis, and a 2–3 times higher risk of PD; Biermer anemia might cause hyperpigmentation by itself), and rheumatologic diseases (lupus induces OU, honeycomb plaques, keratotic plaques, angular cheilitis, buccal petechial lesions, and PD). In more than half of the patients, associated vitiligo involves depigmentation of oral mucosa at different levels (palatal, gingival, alveolar, buccal mucosa, and lips). Celiac disease may manifest xerostomia, dry lips, OU, sialadenitis, recurrent aphthous stomatitis and dental enamel defects in children, a higher prevalence of caries and dentin sensitivity, and gingival bleeding. Oral pigmented lesions might provide a useful index of suspicion for AD in apparently healthy individuals, and thus an adrenocorticotropic hormone (ACTH) stimulation is useful. The spectrum of autoimmune AD comorbidities massively complicates the overall picture of oral manifestations.

Who to screen and how to screen for celiac disease

Celiac disease (CeD) is a chronic gluten-induced enteropathy with plethoric manifestations. The typical manifestations of CeD such as chronic diarrhea and malabsorption are widely recognized, however, many patients have atypical manifestations like iron deficiency anemia, idiopathic short stature, hypertransaminesemia or infertility, etc. These patients often present to the primary care physicians and/or non-gastrointestinal specialties. However, due to a lack of awareness among the healthcare professionals about the various atypical manifestations, many patients are not screened for CeD. In this review, we have summarized the available literature about the prevalence of CeD in various gastrointestinal (chronic diarrhea) and non-gastrointestinal conditions (iron deficiency anemia, short stature, cryptogenic hypertransaminesemia, cryptogenic cirrhosis or idiopathic ataxia etc.) where the diagnosis of CeD should be con-sidered. In addition, we also discuss special scenarios where screening for CeD should be considered even in absence of symptoms such as patients with type 1 diabetes, Down's syndrome, and first-degree relatives of patients with CeD. Further, we discuss the diagnostic performance and limitations of various screening tests for CeD such as IgA anti-tissue transglutaminase antibodies, anti-endomysial antibodies and anti-deamidated gliadin antibodies. Based on the current recommendations, we propose a diagnostic algorithm for patients with suspected CeD.

Oral health-related quality of life in children with celiac disease

PURPOSE

There is limited knowledge about oral health-related quality of life (OHRQoL) in children with celiac disease (CD). This study aimed to assess OHRQoL in children with CD compared to healthy controls.

METHODS

This case-control study included children with CD and healthy controls. Three scales were used to assess OHRQoL in different age groups: 6-7 years, 8-10 years, and 11-14 years. The OHRQoL scores were compared between cases and controls to examine the possible associations between OHRQoL and demographics, socioeconomic status, and oral health.

RESULTS

Overall, 104 children with CD and 104 healthy children (controls) were included. The mean age was 10.67 ± 2.39 years in CD patients and 10.69 ± 2.36 in controls (P = 0.971). Male and female children constituted 50% of each group. Children with CD had significantly higher OHRQoL scores than controls (P = 0.003). Low education levels of parents of children with CD and a higher number of siblings in controls were associated with high OHRQoL scores (P = 0.002, P < 0.020, and P = 0.010, respectively). Recurrent aphthous stomatitis (RAS) increased the OHRQoL scores by 7.5 on average (P = 0.016).

CONCLUSION

Children with CD had poor OHRQoL compared with healthy controls. Poor OHRQoL in children with CD was associated with RAS and with lower parental income and education. RAS was an independent predictor of poor OHRQoL in children with CD.
