Estudo de alterações na cavidade oral em pacientes com doença do refluxo gastroesofágico Study in oral cavity alterations in patients with gastroesophageal reflux disease

RACIONAL: A doença do refluxo gastroesofágico, afecção de elevada e crescente incidência, pode se manifestar através de sintomas típicos (pirose e regurgitação) e atípicos (pulmonares, otorrinolaringológicos e bucais). OBJETIVO:Analisar as alterações na cavidade oral de pacientes com a doença do refluxo gastroesofágico. MÉTODOS: Foram estudados 100 pacientes, sendo 50 acometidos por doença do refluxo gastroesofágico (grupo 1) e 50 controles (grupo 2). Todos os pacientes foram submetidos a exame clínico oral e questionário específico, e naqueles do grupo 1, foram realizadas endoscopia digestiva alta e manometria e pHmetria esofágicas. RESULTADOS: A endoscopia digestiva alta demonstrou esofagite em todos os pacientes, sendo erosiva em 20, não-erosiva em 30 e hérnia hiatal em 38. A pressão média no esfíncter inferior do esôfago foi de 11 ± 4,8 mm Hg e no superior de 75 ± 26,5 mm Hg. Em 42 pacientes do grupo 1 (84%) foi observado refluxo gastroesofágico patológico. O exame clínico oral mostrou: erosões dentárias no grupo 1: 273 faces e no grupo 2: 5; dentes cariados no grupo 1: 23 e 115 no grupo 2; abrasão no grupo 1: 58 e no grupo 2: 95; desgaste por atrito: 408 no grupo 1 e 224 no grupo 2. A face dental mais acometida foi a palatina. No grupo 1, 21 pacientes referiam queixas de aftas freqüentes, 35 sensibilidade dentária, 26 ardência bucal e 42 gosto azedo na boca. Naqueles do grupo 2 estas queixas foram observadas em menor número de pacientes. CONCLUSÕES: Os doentes com doença do refluxo gastroesofágico apresentam maior incidência de erosões dentárias, aftas, ardência bucal, sensibilidade dentária e gosto azedo que os controles e menor incidência de lesões cariosas em relação aos controles.<br>BACKGROUND: The gastroesophageal reflux disease, which has become highly and increasingly incident, may be manifested by typical (pyrosis and regurgitation) and atypical (pulmonary, otorhinolaryngological and buccal) symptoms. AIM: To analyze alterations in the oral cavity patients with gastroesophageal reflux disease. METHODS: One hundred patients were studied being 50 gastroesophageal reflux disease patients (group 1) and 50 controls (group 2). All patients were submitted to an oral clinical exam and specific survey. Patients in group 1 were submitted to upper endoscopy, manometry and esophageal pH monitoring. RESULTS: The upper endoscopy revealed esophagitis in all patients, 20 erosive esophagitis, 30 no-erosive esophagitis and 38 hiatal hernia. Average pressure of the lower esophageal sphincter was 11 ± 4,8 mm Hg and of the upper esophageal sphincter 75 ± 26,5 mm Hg. In 42 patients of group 1 (84%) pathological gastroesophageal reflux was observed. Clinical exams revealed: dental erosions in group 1: 273 faces and in group 2: 5 tooth decays in group 1: 23 and 115 in group 2; abrasion in group 1: 58 and in group 2: 95; attrition wear: 408 in group 1 and 224 in group 2. The most damages was the palatine face. In group 1, 21 patients complained about frequent episodes of cankers sores, 35 of tooth sensibility, 26 of burning mouth and 42 of sour taste in the mouth. In group 2 the complaints were observed in lower number of patients. CONCLUSIONS: Patients with gastroesophageal reflux disease present higher incidence of dental erosion, cankers sores, mouth burning sensation, sensitivity and sour taste than controls. Patients with gastroesophageal reflux disease show lower incidence of tooth decays as compared to controls

Imaging modalities to inform the detection and diagnosis of early caries

BACKGROUND: The detection and diagnosis of caries at the earliest opportunity is fundamental to the preservation of tooth tissue and maintenance of oral health. Radiographs have traditionally been used to supplement the conventional visual‐tactile clinical examination. Accurate, timely detection and diagnosis of early signs of disease could afford patients the opportunity of less invasive treatment with less destruction of tooth tissue, reduce the need for treatment with aerosol‐generating procedures, and potentially result in a reduced cost of care to the patient and to healthcare services. OBJECTIVES: To determine the diagnostic accuracy of different dental imaging methods to inform the detection and diagnosis of non‐cavitated enamel only coronal dental caries. SEARCH METHODS: Cochrane Oral Health's Information Specialist undertook a search of the following databases: MEDLINE Ovid (1946 to 31 December 2018); Embase Ovid (1980 to 31 December 2018); US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov, to 31 December 2018); and the World Health Organization International Clinical Trials Registry Platform (to 31 December 2018). We studied reference lists as well as published systematic review articles. SELECTION CRITERIA: We included diagnostic accuracy study designs that compared a dental imaging method with a reference standard (histology, excavation, enhanced visual examination), studies that evaluated the diagnostic accuracy of single index tests, and studies that directly compared two or more index tests. Studies reporting at both the patient or tooth surface level were included. In vitro and in vivo studies were eligible for inclusion. Studies that explicitly recruited participants with more advanced lesions that were obviously into dentine or frankly cavitated were excluded. We also excluded studies that artificially created carious lesions and those that used an index test during the excavation of dental caries to ascertain the optimum depth of excavation. DATA COLLECTION AND ANALYSIS: Two review authors extracted data independently and in duplicate using a standardised data extraction form and quality assessment based on QUADAS‐2 specific to the clinical context. Estimates of diagnostic accuracy were determined using the bivariate hierarchical method to produce summary points of sensitivity and specificity with 95% confidence regions. Comparative accuracy of different radiograph methods was conducted based on indirect and direct comparisons between methods. Potential sources of heterogeneity were pre‐specified and explored visually and more formally through meta‐regression. MAIN RESULTS: We included 104 datasets from 77 studies reporting a total of 15,518 tooth sites or surfaces. The most frequently reported imaging methods were analogue radiographs (55 datasets from 51 studies) and digital radiographs (42 datasets from 40 studies) followed by cone beam computed tomography (CBCT) (7 datasets from 7 studies). Only 17 studies were of an in vivo study design, carried out in a clinical setting. No studies were considered to be at low risk of bias across all four domains but 16 studies were judged to have low concern for applicability across all domains. The patient selection domain had the largest number of studies judged to be at high risk of bias (43 studies); the index test, reference standard, and flow and timing domains were judged to be at high risk of bias in 30, 12, and 7 studies respectively. Studies were synthesised using a hierarchical bivariate method for meta‐analysis. There was substantial variability in the results of the individual studies, with sensitivities that ranged from 0 to 0.96 and specificities from 0 to 1.00. For all imaging methods the estimated summary sensitivity and specificity point was 0.47 (95% confidence interval (CI) 0.40 to 0.53) and 0.88 (95% CI 0.84 to 0.92), respectively. In a cohort of 1000 tooth surfaces with a prevalence of enamel caries of 63%, this would result in 337 tooth surfaces being classified as disease free when enamel caries was truly present (false negatives), and 43 tooth surfaces being classified as diseased in the absence of enamel caries (false positives). Meta‐regression indicated that measures of accuracy differed according to the imaging method (Chi(2)(4) = 32.44, P < 0.001), with the highest sensitivity observed for CBCT, and the highest specificity observed for analogue radiographs. None of the specified potential sources of heterogeneity were able to explain the variability in results. No studies included restored teeth in their sample or reported the inclusion of sealants. We rated the certainty of the evidence as low for sensitivity and specificity and downgraded two levels in total for risk of bias due to limitations in the design and conduct of the included studies, indirectness arising from the in vitro studies, and the observed inconsistency of the results. AUTHORS' CONCLUSIONS: The design and conduct of studies to determine the diagnostic accuracy of methods to detect and diagnose caries in situ are particularly challenging. Low‐certainty evidence suggests that imaging for the detection or diagnosis of early caries may have poor sensitivity but acceptable specificity, resulting in a relatively high number of false‐negative results with the potential for early disease to progress. If left untreated, the opportunity to provide professional or self‐care practices to arrest or reverse early caries lesions will be missed. The specificity of lesion detection is however relatively high, and one could argue that initiation of non‐invasive management (such as the use of topical fluoride), is probably of low risk. CBCT showed superior sensitivity to analogue or digital radiographs but has very limited applicability to the general dental practitioner. However, given the high‐radiation dose, and potential for caries‐like artefacts from existing restorations, its use cannot be justified in routine caries detection. Nonetheless, if early incidental carious lesions are detected in CBCT scans taken for other purposes, these should be reported. CBCT has the potential to be used as a reference standard in diagnostic studies of this type. Despite the robust methodology applied in this comprehensive review, the results should be interpreted with some caution due to shortcomings in the design and execution of many of the included studies. Future research should evaluate the comparative accuracy of different methods, be undertaken in a clinical setting, and focus on minimising bias arising from the use of imperfect reference standards in clinical studies
