Oral manifestations of inflammatory bowel disease: a review based on the observation of six cases

Inflammatory bowel disease (IBD) comprises two chronic, tissue-destructive, clinical entities: Crohn`s disease (CD) and ulcerative colitis (UC), both immunologically based. Bowel symptoms are predominant, but extra-intestinal complications may occur, including involvement of the oral cavity. Oral involvement during IBD includes several types of lesions: the most common are aphthae; uncommon lesions include, among others, pyostomatitis vegetans and granulomatous lesions of CD. Starting with a presentation of six patients with oral manifestations, which were crucial for the final diagnosis of IBD, a review on the subject is presented. Oral involvement in IBD may be previous or simultaneous to the gastrointestinal symptoms. However, in the majority of cases, bowel disease precedes the onset of oral lesions by months or years. In many patients, the intestinal symptoms may be minimal and can go undetected; thus, most authors believe that the bowel must be thoroughly examined in all patients with suspected IBD even in the absence of specific symptoms. Usually, the clinical course of oral lesions is parallel to the activity of IBD; therefore, oral manifestations are a good cutaneous marker of IBD.

Oral manifestations of human T-cell lymphotropic virus infection in adult patients from Brazil

Objective: Human T-cell lymphotropic virus type 1 (HTLV-1) was the first human retrovirus discovered and its pathogenesis is related to T cells infection. This study aimed to verify the presence of oral manifestations in a Brazilian population of patients who was seropositive for HTLV, and identify risk factors for oral manifestations. Subjects and methods: An assessment was made of 139 patients at the Emilio Ribas Institute of Infectious Diseases. Results: A total of 112 (80.5%) patients were HTLV-1, 26 (18.7%) were HTLV-2+. About 35.2% of patients had myelopathy/tropical spastic paraparesis (HAM/TSP), with 48 of them being HTLV-1+ and one patient was seropositive for HTLV-1 and -2. The most common oral manifestations were: xerostomia (26.8%), candidiasis (20.8%), fissured tongue (17.9%), and loss of tongue papillae (10.0%). A multivariate logistic regression analysis showed that HAM/TSP is an independent risk factor for xerostomia (P = 0.02). The patients who were HAM/TSP+ were three times more likely to develop xerostomia when compared with patients without HAM/TSP (odds ratio = 2.69, 95% confidence interval = 1.17-6.17). Conclusion: Despite the fact that the findings of this study suggest a relationship between xerostomia and HAM/TSP, more studies should be developed to show what the association would be between xerostomia presented by HTLV patients and pathogenesis of the virus.

Oral manifestations after immune reconstitution in HIV patients on HAART

In order to verify possible association between immune reconstitution inflammatory syndrome (IRIS) and oral manifestations (OMs), we selected AIDS patients who had low CD4 count before the initiation of highly active antiretroviral therapy (HAART) and who returned three months later for therapy evaluation. The oral lesions observed three months after the initiation of HAART were evaluated and associated with the type of antiretroviral therapy (ART), CD4 count and HIV-RNA load levels (before and three months after HAART initiation). A total of 105 patients matched the selected criteria. Immune reconstitution (IR) was identified in 35.2%. Among these patients, the mean CD4 cell count rose from 105.97 to 330.29 and the mean viral load dropped from 168.005 (log 5.22) to 21.852 (log 4.33). There was no significant difference in age (P=0.78), sex (P=0.41) or previous history of ART (P=0.55) between IR and non-IR patients. In the IR group, the most common OM was. parotid enlargement (57.14%) (P=0.619), whereas in the non-IR group candidiasis (46.15%) was the most common OM. The results of our study suggest that the parotid gland enlargement found in the studied population might be an IRIS event, as it was found in patients with IR three months after the initiation of HAART.

Oral manifestations of Albright hereditary Osteodystrophy: a case report

Albright hereditary osteodystrophy is a hereditary metabolic disorder of dominant autosomal etiology that is commonly characterized by short stature, round face, small metacarpus and metatarsus, mental retardation, osteoporosis, subcutaneous calcification, variable hypocalcemia, and hyperphosphatemia. In this study, we report a clinical case of a 17-year-old woman with Albright hereditary osteodystrophy, and we discuss her clinical, radiographic, and laboratory test characteristics together with the oral manifestations, and we correlate them with the characteristics found in the literature. We also discuss the odontological management of treatment of related periodontal disease and planning for corrections of related malocclusions.

Lésions buccales du reflux gastro-oesophagien de l'enfant: des réalités et quelques mythes [An interface between pediatrics and oral medicine: oral manifestations of gastroesophageal reflux in children]

Gastro-oesophageal reflux (GOR) is a common disorder in the pediatric population. In association with esophagitis, GOR may impair children's quality of life. Extra-oesophageal manifestations are of specific interest in oral medicine because the refluxate may reach impair both oral mucosa and hard dental tissues. Some oral symptoms are so specific that they should raise the attention for other GOR symptoms. Dental erosion is a potential risk in children with gastroesophageal reflux: the pediatrician should routinely refer children with gastroesophageal reflux to a pediatric dentist to diagnose erosions and if needed restore the teeth. Conversely, in the presence of unexplained dental erosions the dentist and/or the pediatrician should discuss the possibility of an occult GOR.

Tuberous sclerosis complex with oral manifestations: A case report and literature review

Introduction: Tuberous sclerosis complex (TSC) is a neurocutaneous syndrome produced by a number of genetic mutations. The disease is characterized by the development of benign tumors affecting different body systems. The most common oral manifestations of TSC are fibromas, gingival hyperplasia and enamel hypoplasia. Clinical Case: A 35-year-old woman diagnosed with TSC presented with a reactive fibroma of considerable size and rapid growth in the region of the right lower third molar. Discussion: In the present case the association of TSC with dental malpositioning gave rise to a rapidly evolving reactive fibroma of considerable diameter. Few similar cases can be found in the literature. Patients with TSC present mutations of the TSC1 and TSC2 genes, which intervene in cell cycle regulation and are important for avoiding neoplastic processes. No studies have been found associating TSC with an increased risk of oral cancer, though it has been shown that the over-expression of TSC2 could exert an antitumor effect. Careful oral and dental hygiene, together with regular visits to the dentist, are needed for the prevention and early detection of any type of oral lesion. The renal, pulmonary and cardiac alterations often seen in TSC must be taken into account for the correct management of these patients.

Oral manifestations of diabetes mellitus in complete denture wearers

Statement of problem. The oral mucosa has been reported to show a variety of changes in subjects with diabetes mellitus.Purpose. The purpose of this study was to compare diabetic and nondiabetic subjects wearing complete dentures with regard to salivary flow, salivary buffering capacity, denture retention, and oral mucosal lesions.Material and methods. Sixty subjects, 30 with and 30 without a diagnosis of diabetes, were matched for gender, race, and age. Salivary flow, salivary buffering capacity, glycemia, blood pressure, presence of mucosal lesions, denture retention, use of medications, and behavioral factors (controlled or uncontrolled diet, alcohol consumption, and smoking) reported by the subjects, were evaluated. For the salivary buffering capacity test, 1 mL of saliva was pipetted into a test tube containing 3 mL 0.005 N of hydrochloric acid, and the pH was measured with indicator strips. Group differences were statistically analyzed using the Student t test and the Mann-Whitney test for quantitative variables and the chi-square test for qualitative variables (alpha = .05).Results. Mean (SD) salivary flow was 1.14 (0.87) mL/min in the nondiabetic subjects and 0.95 (0.61) mL/min in the diabetic subjects. Evaluation of self-reported denture retention revealed no significant difference between groups. Denture retention was observed in 66.7% (20/30) of the control group and in 50% (15/30) of the diabetic group. The prevalence of mucosal lesions was 90% (27/30) in the control group and 83.3% (25/30) in the diabetic group. Salivary buffering capacity was 5.80 (0.85) in the control group and 5.26 (0.83) in the diabetic group (P = .017).Conclusions. Within the limitations of this study, no significant differences were observed in salivary flow, denture retention, or oral lesions in diabetic and nondiabetic subjects.

Oral manifestations during chemotherapy for acute lymphoblastic leukemia: A case report

A 14-year-old, male patient was referred for the treatment of mucositis, idiopathic facial asymmetry, and candidiasis. The patient had been undergoing chemotherapy for 5 years for acute lymphoblastic leukemia. He presented with a swollen face, fever, and generalized symptomatology in the mouth with burning. On physical examination, general signs of poor health, paleness, malnutrition, and jaundice were observed. The extraoral clinical examination showed edema on the right side of the face and cutaneous erythema. On intraoral clinical examination, generalized ulcers with extensive necrosis on the hard palate mucosa were observed, extending to the posterior region. Both free and attached gingivae were ulcerated and edematous with exudation and spontaneous bleeding, mainly in the superior and inferior anterior teeth region. The tongue had no papillae and was coated, due to poor oral hygiene. The patient also presented with carious white lesions and enamel hypoplasia, mouth opening limitation, and foul odor. After exfoliative cytology of the affected areas, the diagnosis was mixed infection by Candida albicans and bacteria. Recommended treatment was antibiotics and antifungal administration, periodontal prophylaxis, topical application of fluor 1.23%, and orientation on and control of proper oral hygiene and diet during the remission phase of the disease.

Oral manifestations of secondary syphilis in the elderly - A timely reminder for dentists

Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum. Cases of syphilis have increased in frequency and are challenging when affecting the elderly. The main causes of increased prevalence of syphilis are sexual promiscuity, lack of knowledge about the disease and decreasing use of barrier protection. Clinically, the oral manifestation of syphilis may resemble other entities, which hampers the correct diagnosis. We report a case of a 79-year-old male with weight loss and feeding difficulties. In the oral cavity there were ulcerative lesions in the hard palate and bilaterally in the buccal mucosa. The incisional biopsy revealed only a non-specific ulceration of the oral mucosa. After 20 days, the patient was re-evaluated and presented maculopapular lesions in the palmar and plantar areas. Positive serological venereal disease reference laboratory (VDRL) tests confirmed the diagnosis of secondary syphilis. The patient was treated with Benzathine penicillin G. After two weeks of treatment the oral lesion disappeared and the patient returned to normal feeding and gained weight. This case report reinforces the need to alert physicians and dentists to include sexually transmitted infections such as syphilis in the differential diagnosis of oral ulcerative lesions in elderly sexually active patients. © 2013 Australian Dental Association.

Epidemiological and oral manifestations of HIV-positive patients in a specialized service in Brazil

The purpose of this study was to evaluate the prevalence of oral lesions in HIV-positive patients attending the Specialized Service for Infectious-contagious Diseases and Parasitoses of the Health Secretariat of the State of Pará (URE-DIPE/SESPA), in the city of Belém, PA, Brazil. A total of 79 HIV-positive patients (53 males and 26 females) were examined. Clinical and epidemiological evaluations were done by correlating the lesions with gender, race, chronological age, risk behavior and prevailing immune status (CD4+ cells count). Lesion location and the presence of associated factors, such as alcohol use, smoking and denture wearing, were quantified individually for each type of lesion using a diagnostic pattern based on the clinical aspects. Approximately 47% of the patients (n=37) presented some type of oral lesion. Candidiasis (28%) and periodontal disease (28%) were the most common, followed by cervical-facial lymphadenopathy (17.5%). Other lesions observed were hairy leukoplakia, melanin hyperpigmentation, ulcerative stomatitis (aphthous), herpes simplex, frictional keratosis and pyogenic granuloma. This analysis presented some relevance as to the statistical data. Concerning CD4+ cells, most lesions manifested with the reduction of the CD count. There were a larger number of HIV-positive female heterosexual patients. Alcohol and/or smoking were strongly associated with the occurrence of hairy leukoplakia in these patients. Candidiasis and periodontal disease were the most common oro-regional clinical manifestations in the patients.

Oral manifestations in patients with hypogammaglobulinemia

Objective. The overall objective of this study was to assess the oral manifestations and their association with immunologic status and health history, of individuals with hypogammaglobulinemia. Study Design. A case-controlled study of 100 subjects with hypogammaglobulinemia and 93 control individuals was performed. All participants were examined for dental caries, periodontal disease, mucosal lesions/infections, and general oral health problems. Decayed, missing, filled teeth and community periodontal index were recorded. Complete blood count, serum immunoglobulins, and lymphocyte immunophenotyping were measured on the same day of the oral health assessment. Results. Individuals with hypogammaglobulinemia showed higher prevalence of enamel hypoplasia and complaints of dry mouth, and lower prevalence of dental caries and periodontal disease. Conclusions. The systemic conditions associated with hypogammaglobulinemia were not associated with enhanced susceptibility to caries, gingivitis, or periodontitis; however, individuals with hypogammaglobulinemia were more likely to report more episodes of recurrent aphthous ulcers compared with control individuals.

Invasive candidiasis and oral manifestations in premature newborns

Objective: To investigate prevalence of invasive candidiasis in a Neonatal Intensive Care Unit and to evaluate oral diseases and Candida spp. colonization in low birth weight preterm newborns. Methods: A descriptive epidemiological study performed in two stages. First, prevalence of candidiasis was analyzed in a database of 295 preterm patients admitted to hospital for over 10 days and birth weight less than 2,000g. In the second stage, oral changes and Candida spp. colonization were assessed in 65 patients weighing less than 2,000g, up to 4 week-old, hospitalized for over 10 days and presenting oral abnormalities compatible with fungal lesions. Swab samples were collected in the mouth to identify fungi. Results: Prevalence of candidiasis was 5.4% in the database analyzed. It correlated with prolonged hospital length of stay (p<0.001), in average, 31 days, and 85% risk of developing infection in the first 25 days. It correlated with low birth weight (p<0.001), with mean of 1,140g. The most frequent alterations were white soft plaques, detachable, in oral mucosa and tongue. Intense oral colonization by Candida spp was observed (80%). Conclusions: The frequency of invasive candidiasis was low and correlated with low birth weight and prolonged hospital stay. The most common oral changes were white plaques compatible with pseudomembranous candidiasis and colonization by Candida spp. was above average.
