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 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.

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.

A retrospective study of oral manifestations in patients with paracoccidioidomycosis

South American blastomycosis, paracoccidioidomycosis (Pb mycosis) or Lutz disease is an endemically fungal infection in Latin America. It is caused by the dimorphic fungus Paracoccidioides brasiliensis and may cause oral mucosal lesions. The incidence of Pb mycosis oral lesions was evaluated in patients assisted at a Brazilian Dental School's Specialized Oral Diagnosis Service with special focus on the different clinical forms of these lesions, its location, patients' occupation, deleterious habits, and diagnosis methodology. Students' and professionals' initial diagnoses were compared with the definitive diagnosis. Lesions were detected 31 cases (18 patients). The results show that 88.8% of the patients were male with a mean age of 50 years and 39% work(ed) with activities related to agriculture. As much as 88.9% were smokers and 72.2% were alcohol users. Exfoliative cytology was performed in 66.6% of the patients. Oral mucosa (30%), gingiva (16.6%) and lips 16.6% were the most common sites of Pb mycosis oral lesions. Comparing the initial with the definitive diagnosis made by the professionals their accuracy was 33% (6 out of 18 patients). Students' diagnosis was more accurate demonstrating 72.5% of initial correct diagnosis (13 out of 18). Statistical analysis by ANOVA (α=0.05, SPSS WIN) demonstrated a significant difference between the diagnosis of Pb mycosis made by students and professionals when considering initial diagnosis and final diagnosis (after histopathological analysis) (p=0.25). Incisional biopsy and exfoliate cytology are efficient for an early diagnosis of this disease in mouth. Students' training in diagnosis of oral pathologies to recognize lesions is urgent to improve public health.

Oral manifestations in HIV+ children in Mozambique

O objetivo deste estudo foi identificar a prevalência das manifestações bucais em pacientes HIV+/SIDA do Hospital Pediátrico DIA de Maputo. Foram incluídos 90 pacientes na pesquisa. Cárie dentária (índice ceod/CPOD), mucosa e fluxo salivar foram avaliados. Informações sobre alimentação e hábitos de higiene bucal foram obtidas por meio de um questionário. Para a análise estatística foram utilizados os testes t-student e qui-quadrado. A lesão oral mais frequente foi a candidíase (5,5%) e no exame extra-oral foi observada uma prevalência de alargamento da parótida de 23%. A média do ceod foi 2,6 (± 3,6) dentes, consideravelmente alta em relação ao CPOD que foi de 0,6 (±1,6) dentes, sendo esta diferença estatisticamente significante (p<0,05). A ocorrência de lesões na mucosa bucal foi maior em crianças que não faziam uso da terapia antiretroviral (TRA). O uso da TRA esteve associado com a redução da prevalência de lesões bucais em pacientes HIV+, contudo cáries rampantes foram maiores neste grupo. Pacientes HIV+ mostraram maior risco de cáries na dentadura decídua.

Oral manifestations of HIV/AIDS in China: a review

PURPOSE: The purpose of this study is to review the Chinese-language medical and dental literature from 1982 to 2008 on oral manifestations (OMs) of patients with HIV/AIDS for introducing the spectrum of OMs of the patients in China. MATERIALS AND METHODS: All data were extracted from 18 references which had used diagnostic criteria for HIV/AIDS. Four of the references had used the EC-Clearinghouse classification for oral lesions in HIV infection. The feasible overall rate and 95% confidence interval (95%CI) of the data on OMs were calculated. RESULTS: Risk group analysis revealed that, of 203 patients, 64.3% were men and 35.7% were women (age range, 5 months to 64 years; mean age in three studies, 34.0, 34.3, and 36.1 years). Of these patients, 22.2% were infected by sexual contacts, 11.8% by intravenous drug use (IDU), 59.6% by blood or its products, 2.9% by mother to child transmission, and 3.4% were unclear. In 203 patients, oral candidiasis (OC) was the most common lesion (66%, 95%CI = 59.48-72.52%), followed by herpes simplex (HS) (22.2%, 95%CI = 16.48-27.92%), ulcerative stomatitis (14.8%, 95%CI = 9.92-19.68%), salivary gland disease (11.3%, 95%CI = 6.94-15.66%), oral hairy leukoplakia (OHL) (9.8%, 95%CI = 5.71-13.89%), necrotizing gingivitis (5.9%, 95%CI = 2.66-9.14%), Kaposi's sarcoma (2.9%, 95%CI = 0.59-5.21%), other malignant tumors (2.9%, 95%CI = 0.59-5.21%), and linear gingival erythema (2.0%, 95%CI = 0.07-3.93%). CONCLUSIONS: The spectrum of OMs reported from China is similar to that described in the international literature. Present data are useful to supplement international resources of HIV/AIDS research.

Trèlat's beads as oral manifestations in patients with HIV/TB

Tuberculosis (TB) is a contagious infectious disease caused by Mycobacterium tuberculosis (Koch's bacillus). Co-infection with human immunodeficiency virus (HIV) and TB has reached a significant importance as a public health problem and this association has been recognized as the most significant event that changed "the balance between man and Koch's bacillus" in the last century, and has a large contribution to the risk for disease spreading. Tuberculosis has two main standard categories of clinical manifestations: primary and secondary. Primary TB is responsible for the initial infection with lungs being the involved organ. Oral lesions are observed as a secondary TB clinical manifestation with most frequent sites being hard and soft palate, tongue, lips, gums, tonsils, and salivary glands. A case of classical TB lesions in the oral cavity is reported, and the importance of a correct diagnosis through careful history taking is emphasized. Treatment selection needs to be done assertively, with great determination and building a link between patient and treatment protocol, in order to promote patient's adherence.

Les manifestations orales de la maladie de Crohn chez les enfants et les adolescents

Les manifestations orales de la maladie de Crohn sont bien établies chez les adultes. Toutefois, aucune étude ne s’est concentrée sur les manifestations orales pathologiques chez la population infantile. En ce qui concerne la santé dentaire, très peu d’études ont évalué la prévalence de carie chez les patients atteints de la maladie de Crohn. Les objectifs de cette étude sont de décrire les manifestations orales des enfants et des adolescents atteints de la maladie de Crohn et tout lien possible avec le stade de la maladie (active ou rémission) ainsi que de déterminer s’il existe un lien entre la prévalence de carie et le score de potentiel cariogène de la diète des patients. Hypothèses • Les manifestations buccodentaires décrites chez les adultes sont présentes chez les enfants et adolescents du groupe de Ste-Justine. • Il existe différentes manifestations propres à la population infantile. • L’indice carieux des enfants atteints de la maladie de Crohn est supérieur à celui des enfants en bonne santé. • L’indice de potentiel cariogène est élevé chez les patients atteints de la maladie de Crohn • Le stade de la maladie influence la prévalence des manifestations. Méthodologie Un certificat d’éthique à la recherche fut obtenu de l’hôpital Ste-Justine. Sur 40 patients recrutés, 21 sujets (9 filles, 12 garçons) âgés de 5,1 à 17,3 ans ont participé à l’étude de type transversale. Un questionnaire médical, un examen buccal complet, l’analyse des journaux alimentaires ainsi qu’une revue des dossiers médicaux a permis d’établir la prévalence des lésions pathologiques, la prévalence de carie (indice CAO) et le score de potentiel cariogène (SPC) selon la méthode du Dre Monique Julien. Résultats Les analyses statistiques démontrent: • Aucune différence significative entre le CAO des patients atteints de la maladie et celui du groupe contrôle. • Aucune manifestation orale autre que celles présentées dans la littérature. • 57% des patients ont rapporté avoir eu des ulcères buccaux au cours de la maladie. • Les patients en phase active ne sont pas différents de ceux en rémission en ce qui concerne les manifestations orales, le CAO et le SPC. • Les enfants qui prennent du méthotrexate ont un CAO plus élevé. • Les patients qui ont plus de caries n’ont pas nécessairement une diète plus cariogène. Conclusion Selon les résultats de notre étude, nous n’avons pas observé de manifestations orales propre à la population infantile. De plus, les enfants atteints de la maladie ne semblent pas être un groupe à risque de carie dentaire. Davantage d’études sont nécessaires sur les manifestations orales de la maladie de Crohn chez la population pédiatrique.

Oral colonization by Candida species in AIDS pediatric patients

The aim of this study was to assess the prevalence of factors associated with oral colonization by Candida spp. in pediatric patients with AIDS. The sample comprised of 117 children. Clinical status, medicines in use, and laboratory findings were obtained from hospital records; sociodemographic data were given by relatives. A dental examination assessed the prevalence of dental caries. The prevalence of oral colonization by Candida was 62%. Only seven children presented clinical manifestation of oral candidosis despite their high viral load index and low-for-age CD4 count. Candida colonization was directly associated with frequent use of antibiotics (prevalence ratio [PR] = 1.44), sulfa drugs (PR = 1.23), alteration in the oral mucosa (PR = 1.55), and untreated dental caries (PR = 1.93). It was inversely associated with the use of antiretroviral therapies (PR = 0.65). Candida albicans was the most frequently detected species (80%); phenotypic tests did not detect C. dubliniensis strains. This study observed a low prevalence of Candida-related oral lesions in these patients, which is compatible with the hypothesis that antiretroviral medicines may have contributed to reducing oral manifestations from Candida infection. The high prevalence of Candida colonization in HIV+/AIDS children with untreated dental caries reinforces the importance of oral health care in interdisciplinary health units that assist these patients.

Avaliação clínica e microbiológica das condições de saúde oral dos receptores de transplante renal do Hospital Universitário Onofre Lopes, Natal RN

Introduction: The chronic immunosuppression promotes the development of changes in the oral cavity of the kidney transplant recipients (KTR), however with the exception of gingival overgrowth, little is known regarding the prevalence of oral lesions in this population. Objective: To evaluate the prevalence of clinical and microbiological conditions of the oral cavity of the recipients of kidney transplantation and the associated factors. Methods: This was a cross-sectional study which examined 96 clinical KTR and experimental where collected saliva stimulated them to identify Candida sp. Data collection consisted of evaluation stomatologic, socio-demographic, clinical aspects of transplantation, condition of oral hygiene and dental caries, yonder to questions about knowledge of oral alteration after transplantation. Results: Of the total, 66.7% of KTR had some type of oral manifestation. The most common was saburral tongue, followed by gingival overgrowth, with both oral manifestations related to gender and concomitant use of cyclosporine and nifedipine (p <0.05). Tacrolimus showed a protective effect for gingival overgrowth (OR = 0.13). The oral hygiene was associated with saburral tongue(p = 0.03) and severity of gingival overgrowth (p = 0.0001). Oral candidiasis was diagnosed in 17.7% of patients and Candida albicans was isolated most frequently in the saliva of RTR with a colonization of 58.3%. The average DMF-T increased with age. The method of oral hygiene was most used brush and toothpaste to 61.5%. Changes in the oral cavity was seen in 54.2% of KTR, citing as the main growth and gingival ulcers. Instructions for oral hygiene after transplantation were neglected for 61.5% of RTR. Dry mouth and halitosis were reported in 30.2% and 36.5% respectively. Conclusions: More the half of the KTR had at least one injury of the mouth, the immunosuppressive drugs and oral hygiene are associated with these alterations. Prospective cohort studies are needed to elucidate the relationship between oral manifestations and levels of drug and risk of oral manifestations occur over time. The kidney transplant recipients showed to be aware of oral alterations occurred after transplantation and uninformed about the oral hygiene instructions. With regard to hygiene, the incidence of caries was considered high, conditions of risk were identified and improvements in primary attention should be encouraged and reflected in the monitoring of renal transplant
