Abstract
The use of cocaine and its main derivative, crack, can cause some systemic effects that may lead to the development of some oral disorders. To assess the oral health of people with a crack cocaine use disorder and identify salivary protein candidates for biomarkers of oral disorders. A total of 40 volunteers hospitalized for rehabilitation for crack cocaine addiction were enrolled; nine were randomly selected for proteomic analysis. Intraoral examination, report of DMFT, gingival and plaque index, xerostomia, and non-stimulated saliva collection were performed. A list of proteins identified was generated from the UniProt database and manually revised. The mean age (n=40) was 32 (±8.88; 18-51) years; the mean DMFT index was 16±7.70; the mean plaque and gingival index were 2.07±0.65 and 2.12±0.64, respectively; and 20 (50%) volunteers reported xerostomia. We identified 305 salivary proteins (n=9), of which 23 were classified as candidate for biomarkers associated with 14 oral disorders. The highest number of candidates for biomarkers was associated with carcinoma of head and neck (n=7) and nasopharyngeal carcinoma (n=7), followed by periodontitis (n=6). People with a crack cocaine use disorder had an increased risk of dental caries and gingival inflammation; less than half had oral mucosal alterations, and half experienced xerostomia. As possible biomarkers for 14 oral disorders, 23 salivary proteins were identified. Oral cancer and periodontal disease were the most often associated disorders with biomarkers.

Abstract
BACKGROUND/PURPOSE Actually, many individuals have opted for the vegetarian diet. The objective of this study was to evaluate the impact of the vegetarian diet on the oral epithelium through cytopathology. METHODS Oral smears of the tongue and buccal mucosa of 60 adult subjects (30 vegetarians and 30 controls) were collected. Smears were analyzed morphologically and for three morphometric variables: nucleus area (NA), cytoplasm area (CA) and nucleus/cytoplasm ratio. RESULTS Vegetarians were classified as ovolactovegetarian (53.3%), vegans (30%) and strict vegetarians (16.7%). The NA and CA of the epithelial cells of vegetarian individuals were smaller when compared to controls both in the region of the buccal mucosa and tongue. However, there was no statistically significant difference according to the Student's t-test. For the NA/CA ratio, cells in the oral mucosa region were larger for vegetarians compared to controls. For the tongue, both groups had the same value and the Mann-Whitney U test confirmed that there is no difference between the groups for this cytomorphometric variable. RESULTS Vegan individuals had a smaller (but not larger) area of CA when compared to controls for the tongue (vegan = 2604.2 ± 179.2 versus control = 3256.7 ± 463.8 p = 0.013). Most smears showed normal epithelial cells and some individuals had changes of an inflammatory nature, mainly in the tongue. CONCLUSION Despite the small sample size, the results of this study raise the hypothesis that the vegetarian diet (especially the vegan diet) can compromise the thickness of the oral epithelium of the tongue.

Abstract
Background This study aimed to investigate the morphology and chemical composition of dental caries related to ionizing radiation (DCIR), an aggressive and progressive disease that affects dental hard tissues. Materials and methods Eight human teeth with DCIR were paired with sixteen control teeth (8 teeth with conventional caries and 8 without caries) and included in this study. An analysis of the morphology of the lesions was performed using the following techniques: periapical radiography, cone beam computed tomography, computed microtomography, and scanning electron microscopy. The chemical composition was assessed using X-ray dispersive spectroscopy. Results There was more demineralization in DCIR lesions when compared to conventional dental caries, even though there was no cavitation in the cervical region of the teeth. The superficial roughness and topography of DCIR lesions were similar to those of healthy teeth. On the other hand, lesions of conventional dental caries showed greater surface and topographic irregularity when compared to DCIR and healthy teeth (p = 0.001). Calcium (Ca) and phosphorus (P) levels were lower in DCIR lesions when compared to controls. However, higher levels of carbon (C) have been observed in DCIR lesions. There was a greater loss of the mineral matrix in DCIR followed by conventional caries. The reduction in the mineral matrix (Ca and P) was compatible with the imaging patterns observed in teeth with DCIR and conventional caries. Conclusion Despite their rapid evolution, DCIR presents an irregular, apparently intact surface with significant changes in the amount of Ca, P, and C.

Abstract
AIMS The aim of the present study was to evaluate the taste perception in patients with upper complete dentures. METHODS AND RESULTS One hundred seventy male and female patients (45-83 years old) upper denture wearers were evaluated for their gustatory function by the paper strips technique in relation to the four basic tastes. The taste test was performed with and without the presence of the denture on the palate. Through Shapiro-Wilk and Kolmogorov-Smirnov tests, the results were analyzed by their normal distribution. The t-test for paired samples was used to evaluate if there was a statistical difference on the taste perception and itself revealed that there is a significant difference (p < 0.01) when the taste perception was analyzed for the absence and presence of the prosthesis (alone and compared) (p < 0.01). The results revealed that patients with dentures had great difficulty to recognize the bitter taste, followed by the salty, sweet, and sour. CONCLUSION The presence of the denture was able to modify the perception of taste when compared to its absence, especially for the bitter taste.

Abstract
OBJECTIVE Salivary proteomic analysis may help to understand physiopathological changes in crack cocaine dependents. This study aimed to compare the salivary protein profile between crack cocaine dependents and non-drug users. DESIGN Nine heavy smokers and alcohol consumers men admitted to rehab due to crack cocaine abuse and nine non-drug users age-matched men were evaluated. Unstimulated whole saliva was collected. Proteomic analysis was performed by mass spectrometer. Data were processed using ProteinLynx GlobalServer software. Results were obtained by searching the Homo sapiens database from the UniProt catalog. The search tool IBI-IMIM was used to identify proteins candidates for biomarkers. RESULTS The mean age of crack cocaine and control groups was 36.89 ± 7.78 and 35.78 ± 6.68 years, respectively. 458 salivary proteins were identified in both groups; 305 proteins in the crack cocaine group. Among the 68 proteins presented in both groups, 29 were down-regulated (i.e. "Statherin" and "Transforming growth factor-beta-induced protein ig-h3" were down-regulated at least 10-fold) and 27 up-regulated (i.e. "Negative elongation factor" was up-regulated 19-fold) in the crack cocaine group compared to controls. 90 out of the 458 proteins found in the proteomic analysis were identified as candidates for biomarkers of diseases. Among these, 65 (72.22 %) were detected in the crack cocaine group. CONCLUSION Crack cocaine dependents with chronic alcohol and tobacco use have a higher number of proteins in saliva compared to non-drug users. 22.3 % of salivary proteins present in crack cocaine dependents were present in controls; 3.9 % of them were expressed in similar quantity.

Abstract
OBJECTIVES To evaluate the oral condition of alcohol and tobacco dependents and identify salivary protein candidates for biomarkers of oral disorders. SUBJECTS AND METHODS Thirty-three male volunteers were evaluated for alcohol abuse rehabilitation; nine were selected for proteomic analysis. Intraoral examination was performed, and non-stimulated saliva was collected. Salivary proteins were extracted and processed for analysis. A list of proteins identified in saliva was generated from the database and manually revised, obtaining the total number of candidate biomarkers for oral disorders. RESULTS The mean age (n = 33) was 42.94 ± 8.61 years. Fourteen (42.4%) subjects presented with 23 oral mucosa changes, and 31 (94%) had dental plaque. A total of 282 proteins were found in saliva (n = 9), of which 26 were identified as candidates for biomarkers of oral disorders. After manual review, 21 proteins were selected. The highest number of candidates for biomarkers was associated with carcinoma of head and neck (n = 10), nasopharyngeal carcinoma (n = 6), and periodontal disease (n = 6). CONCLUSION Alcohol and tobacco dependents showed gingival inflammation, and less than half of them showed oral mucosa changes. Twenty-one protein candidates for biomarkers of oral disorders were identified in saliva. The two major oral disorders in number of candidates for biomarkers were head and neck cancer and periodontal disease.

Abstract
BACKGROUND Alcohol and substances found in tobacco may alter salivary flow and amount of saliva proteins. This study aimed to compare salivary proteins between alcohol dependent smokers and controls. METHODS This is a case-control study with men older than 18 years of age, matched by age. The alcohol-dependent group was composed by heavy smokers and alcohol consumers. Unstimulated whole saliva was collected from all subjects. Analysis of digested peptides was performed in mass spectrometer. Data were processed using ProteinLynx GlobalServer software. Results were obtained by searching theHomo sapiens database from the UniProt catalog. The search tool IBI-IMIM was used to identify candidate proteins for biomarkers. RESULTS Alcohol-dependent and control groups were composed of nine participants each, with mean age of 36.89 ± 2.57 and 35.78 ± 1.64 years, respectively. 404 salivary proteins were found in both groups; 282 in the alcohol-dependent. Among the 96 proteins presented in both groups, 32 were up-regulated in the alcohol dependents (i.e. "Hemoglobin subunit beta" and "Forkhead box protein P2" were up-regulated at least 10-fold), 23 were down-regulated (i.e. "Statherin" and "RNA-binding protein 25" were down-regulated at least 10-fold), and 41 presented similar expression in both groups. 71 proteins were candidates for biomarkers of disorders 58 presented in alcohol dependents' saliva. The most common disorders were neoplasms, genetic, cardiovascular, metabolic and glandular diseases. CONCLUSIONS Salivary protein profile undergoes strong changes in alcohol and tobacco dependents. 34% of salivary proteins present in alcohol and tobacco dependents were present in controls; 14.5% of them were expressed in similar quantity.

Abstract
OBJECTIVE The aim of this study was to evaluate the perception of taste in HIV-infected patients. METHOD One hundred males and females (11 to 60 years old) were divided into two groups (50 patients infected by HIV and 50 controls) and evaluated for gustatory function. RESULTS The results revealed that the mean score in the evaluation of taste was significantly lower in individuals with HIV when compared to controls for both sides of the tongue (p < 0.05). Patients with HIV infection had difficulty recognizing the bitter taste, followed by salty and sweet. When each side of the tongue was evaluated separately and compared, the Wilcoxon test showed that there was no significant difference on the tongue of individuals with HIV. The prevalence of hypogeusia was 20% in individuals with this disease. CONCLUSIONS Individuals with HIV infection may have a deficit in taste that can affect your general and oral health.

Abstract
BACKGROUND The health risks of crack cocaine smoking on the oral mucosa has not been widely researched and documented. OBJECTIVE The purpose of this study was to analyze the proliferative activity of oral epithelial cells exposed to crack cocaine smoke using silver nucleolar organizer region (AgNOR) staining. METHODS Oral smears were collected from clinically normal-appearing buccal mucosa by liquid-based exfoliative cytology of 60 individuals (30 crack cocaine users and 30 healthy controls matched for age and gender) and analyzed for cytomorphologic and cytomorphometric techniques. RESULTS Crack cocaine users consumed about 13.3 heat-stable rocks per day and the time consumption of the drug was of 5.2 (± 3.3) years. Mean values of AgNOR counting for case and control groups were 5.18 ± 1.83 and 3.38 ± 1.02 (P<0.05), respectively. AgNOR area and percentage of AgNOR-occupied nuclear area were increased in comparison with the control (P<0.05). There was no statistically significant difference in the mean values of the nuclear area between the groups (P>0.05). CONCLUSION This study revealed that crack cocaine smoke increases the rate of cellular proliferation in cells of normal buccal mucosa.

Abstract
Keratoacanthoma is a lesion typical crater, symmetrical, rounded, rapid growth with high potential for self-involution. The lesions may be multiple, disseminated and associated with some syndromes. The etiology of keratoacanthoma is not known, but it is often observed in patients chronically exposed to sun. Histopathological features of keratoacanthoma may resemble those of a well differentiated squamous cell carcinoma. The hallmark of the disease is spontaneous resolution after an intermediary stationary stage. The majority of the cases is treated by surgical excision. For this reason, very few cases have been documented until resolution, which constitutes the gold standard for this clinic diagnosis. The aim of this article is to report a case of keratoacanthoma in the inferior lip of an immunosuppressed patient.
