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
Introduction: The causal mechanisms behind crack/cocaine use are still unknown, but genetic influences are suggested. Objective: To investigate the relationship between the genetic polymorphism TaqI (rs1800497) in the dopamine D2 receptor (DRD2) gene and susceptibility to crack/cocaine dependence in a group of addicts to crack/cocaine and a non-addicted group. Methods: The case group (n=515) was composed of crack/cocaine-dependent men and the control group (n=106) comprised men who were considered not dependent on crack/cocaine. The oral hygiene habits, decayed, missing, and filled teeth index, gingival index, and plaque index were evaluated. The reference single nucleotide polymorphism (rs1800497 C/T) of the DRD2 gene was genotyped by a real-time polymerase chain reaction technique. Student’s t-tests for independent samples or the non-parametric Mann-Whitney test were used to compare groups regarding quantitative variables. Results: The case group showed a mean time of 9.91±7.03 years of crack use, and 61.06±92.96 stones/week. The socio-demographic profile of the sample was White, single men, with basic education, blue-collar worker, smoker, and reporting alcohol use. There was a high frequency of gingival inflammation, plaque accumulation, and caries experience. For all genetic models tested, there was no significant difference in the genotypic frequency in rs1800497 of the DRD2 gene, between case and control groups (p>0.05). Conclusion: The genetic variant in the DRD2 did not increase the vulnerability to develop crack/cocaine dependence. The complex genetic nature of crack/cocaine dependence and a large variation of DRD2 allele frequencies, depending on the population group sampled, could be one explanation for the no association.

Abstract
PURPOSE To evaluate the electromyographic (EMG) activity of masseter muscles (MMs) after the provision of new complete dentures (CDs) and to assess the possible correlations between clinical behavior and the EMG findings. MATERIALS AND METHODS The sample included 78 edentulous participants (56 women, 22 men; mean age: 65.59 ± 10.47 years). Prior to provision of the new CDs, surface EMG activity of the masseter muscles was recorded during rest, maximum voluntary contraction, and mastication (MAST) using a wax artifact (WA). The tests were repeated using the new CDs, followed by the WA, at 7 days, 14 days, 21 days, and 10 months. At each assessment after placement of the CDs, the participants were questioned regarding five parameters (comfort, esthetics, retention, mastication, and speech). RESULTS There was an initial decline in the EMG activity of the masseter muscles after the provision of new CDs during MAST, followed by a gradual increase in this activity over time (P > .05). There was a significant improvement in MAST reported by participants at 10 months (3.59 ± 1.141) compared to 7 days (2.50 ± 1.058) (P = .011). There was no significant correlation between the EMG findings and the clinical parameters (P > .05). CONCLUSION Although there was no significant difference in EMG activity of the MMs over time, an improvement in MAST reported by the participants was observed.

Abstract
OBJECTIVE To examine oral colonization and virulence factors of Candida spp. in patients aged from 0 to 18 months with cleft palate (CP). MATERIALS AND METHODS Sixty babies were allocated into 3 groups: CP, CP with orthodontic plate (CPwP), and control group (Ctrl) without CP. Information on feeding habits, hygiene, and history of candidosis was collected. The presence of Candida spp. was investigated in samples of saliva. Fungal hydrophobicity, protease, esterase, phospholipase, and hemolysin were evaluated in a semiquantitative manner. RESULTS Positive oral isolations of Candida spp. were detected in CP (89.5%), CPwP (100%), and Ctrl (44%) groups. Candidosis was more reported in the cleft groups than in the Ctrl group (P ≤ .023). There was a higher prevalence of Candida albicans, followed by Candida krusei, Candida tropicalis, and Candida parapsilosis in all groups. There was no uniformity of expression of virulence factors, either among different species or among different groups. CONCLUSION Candida spp. colonization occurred in all groups, being superior in CPwP group. Candidosis episodes were more reported in patients from CPwP than in other groups, although candidosis was also registered in other groups. Candida albicans was the predominant species and virulence factors did not exhibit any pattern for species or groups of patients.

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
Urine has been a biological matrix of choice for drug screening, but recent advances in technology and the introduction of commercial oral fluid assays have effectively established oral fluid as a viable alternative matrix. This systematic review aimed to evaluate the sensitivity of oral fluid in detecting some illicit drugs compared to urine, and to compare the initial and final detection times of these drugs in both fluids. The electronic search in MEDLINE, Cochrane Library, Scopus, and Web of Science was carried out covering studies published from January 2003 and June 2019, in order to find all valid studies that detected drugs in oral fluid and urine in the same patient. Studies about illicit drugs, such as tetrahydrocannabinol, cocaine, amphetamines and illicit opioids, with fluids collection at the same day, controlled drug administration during the study, reported administration interval and time of collection were favored. Out of 2598 studies identified by electronic search, 7 studies were selected for qualitative analysis. Five were clinical trials and 2 were crossover trials. In total, 74 patients aged 20-52 years underwent a diagnostic examination (4 studies with tetrahydrocannabinol, 1 with methamphetamine, and 2 with cocaine) after drug administration. Illicit drug detection in oral fluid is similar to urine but oral fluid has a strong potential for the immediate detection of recent marijuana use compared to urine. In relation to cocaine and methamphetamine, the largest drugs detection window is obtained through urine analysis. Oral fluids cannot replace urine for most of the purposes of drug testing.

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
Rugby is played by more than 3 million people in over 100 countries on 5 continents. Playing rugby can result in 2-3 times more dental and facial trauma than American football or other contact sports. Facial trauma in sports has been associated with the development of temporomandibular disorders (TMDs). This study aimed to determine the prevalence of TMDs in rugby players. The Research Diagnostic Criteria for Temporomandibular Disorders were used to assess 30 rugby players (group 1) and 28 nonathletes (group 2) for TMDs. The chi-square test was used to compare the groups, and a significance level of 5% (P < 0.05) was used for all statistical analyses. The prevalence of TMDs in groups 1 and 2 was 53.3% and 14.3%, respectively (P = 0.002). Myofascial pain was observed in 12 individuals (40%) in group 1 and in 2 individuals (7.1%) in group 2. Seven participants in group 1 (23.3%) received a diagnosis of disc displacement, and 2 participants (7.1%) in group 2 received this diagnosis. Participants in group 1 also reported significantly more tooth clenching than those in group 2 (P = 0.003).

Abstract
PURPOSE This retrospective chart review study assessed patient records to determine implant insertion torque (IT) and implant stability quotient (ISQ) values during implant placement to evaluate the correlation with cortical bone anchorage (mono- or bicortical). METHODS Primary stability data (IT during implant placement surgery and ISQ values immediately after implant placement) and cone beam computed tomography of 33 patients (165 implants) were assessed. Patients were divided into the following groups: G1, implants with apical cortical bone contact; G2, implants with bicortical bone contact (apical and cervical regions); and G3, implants with cervical cortical bone contact. RESULTS Sixty-eight implants were excluded due to cortical bone contact on regions other than implant apical or cervical. Ninety-seven implants were therefore assessed for this study. No implant failure was found after a mean 70.42-month follow-up time. Implants with bicortical anchorage (G2) showed higher IT (64.1 Ncm) during implant placement and higher ISQ values (76) (p < 0.05). Monocortical implants (G1, apical, and G3, cervical) showed similar IT (G1 52.3 and G3 54.3) and ISQ values (G1 71.9 and G3 73) (p > 0.05). No correlation (Pearson correlation coefficient) was found between the two stability measurement devices for the different cortical bone anchorages that were analyzed (G1 0.190, G2 0.039, and G3 - 0.027) (p > 0.05). CONCLUSIONS Insertion torque values and implant stability quotients were influenced by cortical bone contact. No significant correlation was found between IT and ISQ values-higher insertion torque values do not necessarily lead to higher implant stability quotients.

PURPOSE To compare the survival rate of short implants and standard implants when used in posterior single crowns, in addition to reporting marginal bone loss, prosthetic failures, and surgical complications. MATERIALS AND METHODS Electronic search (PubMed, LILACS, Cochrane Library, Scopus, and Web of Science) and hand search were performed to identify all randomized controlled trials (RCTs) and controlled clinical trials (CCTs) that evaluated both short and standard implants in posterior single crowns. RESULTS Out of 345 articles identified by both electronic and hand search, four studies were selected (one CCT and three RCTs). The meta-analysis for the survival rate showed that there was no significant difference between the short implants and the standard ones (P = 1.00; RR:1.00; CI:0.97-1.03) performed with three RCTs for a one-year follow-up. The mean marginal bone loss ranged from 0.1 mm to 0.54 mm. Only one study reported the presence of prosthetic failures and surgical complications. CONCLUSIONS The survival rate of short implants was similar to the standard ones in posterior single crowns, for the one-year follow-up period. They also presented low surgical complications, prosthetic failures and marginal bone loss, being a predictable treatment for single rehabilitation in posterior tooth loss.

Abstract
Nonsyndromic cleft lip with or without cleft palate (NSCL±P) compromises oral health, leading to missing or malformed teeth, and hampering oral hygiene. Apart from anatomic damages, NSCL±P also culminates in an impact on the routine quality of life with social privation and psychological embarrassment.

Abstract
OBJECTIVE To evaluate cytopathological changes in epithelial cells of the oral mucosa of patients with oral lichen planus (OLP) compared with patients without OLP. SUBJECTS AND METHODS Swabs were collected from the oral mucosa of 20 patients with OLP (case group) and 20 patients without OLP (control group) using liquid-based cytology. After Papanicolaou staining, the smears were characterized based on Papanicolaou classification and degree of maturation. Nuclear area (NA) measurements, cytoplasmic area (CA) measurements, and the NA/CA ratio were determined from 50 epithelial cells per slide. For quantification of argyrophilic nucleolar organizer regions (AgNORs), the smears were stained with silver nitrate, and the number of AgNORs was counted in 100 cells. RESULTS In both groups, there was a predominance of Papanicolaou Class I nucleated cells in the superficial layer. The average values of NA (p>0.05) and CA (p=0.000) were greater in the case group (NA=521.6, CA=22,750.3) compared with the control group (NA=518.9, CA=18,348.0). The NA/CA ratio was 0.025 for the case group and 0.031 for the control group (p=0.004). There was no significant difference between the mean AgNORs values of both groups (p>0.05). CONCLUSION The oral mucosa of patients with OLP exhibited significant cytomorphometric changes. However, there was no evidence of malignancy.

Abstract
AIMS To evaluate cytological alterations, inflammation, and microbial charge of the oral mucosa epithelium in crack users in in terms of the amount and duration of use. METHODS Two hundred thirty four crack users (case group) and 120 non-users (control group) participated in this study. Clinically healthy epithelial cells were collected from the posterior mouth floor, using the conventional exfoliative cytology. Some of the aspects evaluated were as follows: Papanicolaou classification, nuclear area (NA), cytoplasmic area (CA), nuclear/cytoplasmic area ratio (NA/CA), inflammation, microbial charge, keratinization, enucleated superficial cells, and binucleation. RESULTS The average time of crack consumption was 9.8 years (±7.1) and the average quantity of use was 13.97 g/week (±18.5). The average NA values and NA/CA ratio were increased and CA values were decreased in the case group compared to those in the controls (p < 0.05). Papanicolaou class II, intense inflammation, and intense microbial charge were more prevalent in the case group than in the controls (p < 0.05). There was a significant association between high quantity of smoked crack rocks per week and increased CA values, absence of keratinization, and presence of enucleated superficial cells (p < 0.05). CONCLUSION Crack use seemed to induce inflammatory alterations and early indicators of malignant transformation on the oral mucosa epithelium.

Abstract
BACKGROUND The objective of the study was to analyze salivary flow rate, urea concentration, and buffer capacity in adolescents with type 1 diabetes mellitus (type 1 DM) in two different stages. METHODS This study was performed on adolescents (14-19 years), allocated between two groups: type 1 DM group comprised 32 adolescents with type 1 DM, and non-type 1 DM group comprised 32 nondiabetics. The adolescents in type 1 DM group were evaluated at a baseline (T0) and after 15 months (T1), and those in non-type 1 DM group were only evaluated at T0. Diabetic status was determined by glycosylated hemoglobin (GHb) and capillary glucose tests. Measurement of salivary flow was performed by means of stimulated saliva (SSFR) collection. The buffer capacity (BC) was determined, and analysis of urea salivary concentration was performed using the colorimetric method. RESULTS At T0, there were significant differences between diabetics and nondiabetics for SSFR and BC (p<0.05). In diabetics, SSFR was 0.790 mL/min in T0 and 0.881 mL/min in T1 (p>0.05). BC at T0 was 4.8, and at T1, it was 3.9 (p=0.000). Urea concentration mean value had a significant decrease at T1 (28.13) compared with T0 (34.88) (p=0.013). There was a negative correlation between SSFR and urea salivary concentration at both T0 (r=-0.426, p≤0.05) and T1 (r=-0.601, p≤0.01). CONCLUSIONS In adolescents with type 1 DM, hyposalivation at T0 was associated with an increase in urea salivary concentration. At T1, hyposalivation was associated with a reduction in BC, and an increase in salivary urea.

Abstract
AIMS To analyze and compare the electromyographic activity of the temporal (anterior portion) and masseter muscles among Karate-Dō athletes before and after training, with and without the use of a mouthguard. METHODS Twenty athletes (14 males and 6 females) with a mean age of 23.7 ± 7.5 years participated. They had surface electromyography recordings taken of their bilateral temporal and masseter muscles before and after training under the following conditions: no mouthguard, with a ready-made mouthguard, and with a custom-made mouthguard. Activity was examined at mandibular rest, while clenching, and at maximum voluntary contraction. The data were normalized using the mean maximum voluntary contraction. RESULTS The right (p = 0.005) and left (p = 0.015) temporal muscles showed significantly lower electromyographic activity with a custom-made mouthguard compared with no mouthguard after training while clenching. The electromyographic activity of the temporal and masseter muscles did not show significant differences when tested at mandibular rest and while clenching before or after training with a custom-made mouthguard (p > 0.05). CONCLUSION The use of a custom-made mouthguard preserved participants' electromyographic profiles before and after training; thus, they allow for stable muscle activity during the training of Karate-Dō athletes.

Abstract
BACKGROUND/AIM Facial trauma in sports has been associated with temporomandibular disorders. Because of the intensity and duration of training needed for elite-level competitions, high-performance athletes can have two to five times more traumatic injuries than recreational athletes. This study aimed to investigate the prevalence of temporomandibular disorders in high-performance martial arts fighters and compare it with the prevalence in recreational athletes and non-athletes. MATERIAL AND METHODS The Research Diagnostic Criteria for Temporomandibular Disorders was used to diagnose and classify professional karate-do practitioners (group I; n = 24), amateur karate-do practitioners (group II; n = 17), high-performance mixed martial arts fighters (group III; n = 13), and non-athletes (n = 28). The groups were compared with the chi-square test and tested for the difference between two proportions using a significance level of 5% (P < 0.05). RESULTS The prevalence of temporomandibular disorders in groups I (54.2%; P = 0.003) and III (61.5%; P = 0.002) was significantly higher than in group IV (14.3%). The prevalence in group II was similar to that in group IV (P > 0.05). A diagnosis of arthralgia from disk displacement was made more frequently in groups I (45.8%; P = 0.013) and III (38.5%; P = 0.012) than in group IV (7.1%). The chronic pain associated with TMD was low intensity and low disability. CONCLUSIONS While there was a high prevalence of temporomandibular disorders in the professional athletes in our study, the prevalence of the condition in recreational athletes was similar to that in individuals who did not practice martial arts.

Abstract
OBJECTIVE The aim of this study was to evaluate the electromyographic activity of both the temporalis and masseter muscles and the mastication type of patients with skeletal unilateral posterior crossbite before and after orthodontic treatment and speech therapy. METHODS A total of 14 patients with skeletal unilateral posterior crossbite (eight females and six males), between 6-13 years of age, underwent electromyographic evaluation of their masseter and temporalis muscles in mandibular rest, habitual mastication and isometry. The subjects were assessed with regard to mastication type before and after orthodontic treatment and speech therapy. The data obtained during mandibular rest and habitual mastication were normalized in terms of the mean values of isometry. The Student's t-test was used for paired samples to compare the mean values of electromyographic activity (p < 0.05). RESULTS The masseters during habitual mastication presented higher electromyographic activity after both treatments (p = 0.0458). There was no significant difference between the contralateral masseters in terms of mandibular rest or habitual mastication before or after either treatment (p > 0.05). During habitual mastication, after the treatments, the temporalis muscle on the malocclusion side showed higher electromyographic activity than the contralateral side (p = 0.0263). Prior to therapy, all of the patients exhibited chronic unilateral mastication (n = 14) and 13 patients exhibited bilateral mastication after treatment. CONCLUSIONS Orthodontic intervention combined with myofunctional therapy in patients with skeletal unilateral posterior crossbite provided an increase in the electromyographic activity of the masseter and temporalis muscles during mandibular rest and habitual mastication, with predominantly bilateral mastication.

Asymptomatic mouth floor enlargements may be observed in edentulous patients. These
masses, which protrude from the mouth floor, may complicate the fitting of dentures
and require surgery. Whether this "entity" may be considered an anatomical variation
of the mouth floor or represent specific alterations in the sublingual gland is not
known.

Abstract
Background: Sickle cell anemia (SCA) is an autosomal recessive genetic disorder, characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs, consequence of vaso occlusive phenomenon and vasculopathy. Several forms of the chronic anemia, consequence of hemolysis, can be associated with oral epithelial cells changes. Exfoliative cytology can be used to detect real changes in the oral mucosa in SCA. Aims: To evaluate morphometric and morphological changes in oral epithelial cells by exfoliative cytology in children with SCA. Materials and Methods: Oral smears were collected from clinically normal-appearing mucosa by liquid-based exfoliative cytology in 20 SCA children (SCA group) and 20 healthy children (C group), matched for age and gender. The slides were prepared and stained by the Papanicolaou technique. Cell morphology and cellularity were analyzed and compared by Chi-square test (P < 0.05). Images of 50 cells per slide were captured and the nuclear area (NA) and cytoplasmic area (CA) were analyzed using an image analysis system. The nucleus-to-cytoplasmic area ratio (NA/CA) was calculated. To compare the means of groups SCA and C, the Student's t-test (P < 0.05) was applied to NA and CA; test non-parametric Mann Whitney U (P < 0.05) was used to compare NA/CA. Results: Mean values for SCA and C groups were: NA (69.38 and 59.63 μm²; P = 0.01); CA (2321.85 and 2185.60 μm²; P = 0.24); NA/CA (0.03 and 0.02; P = 0.13), respectively. A significant increase in NA for SCA group (P = 0.01) was seen. No morphological differences were found between the groups. There was a predominance of nucleated cells of the superficial layer in the smears of both groups. Class I smears were predominant in both groups. Conclusions: This study revealed that SCA was able to induce significant changes on nuclear area of the oral epithelial cells.

Abstract
OBJECTIVE To evaluate the impact of xerostomia on the quality of life (QOL) of people living with HIV/AIDS (PLWHA) from Brazil. STUDY DESIGN A cross-sectional study was performed on 195 PLWHA. Xerostomia was detected by asking a question about the sensation of having "dry mouth," and Oral Health Impact Profile 14 (OHIP-14) was used to measure the impact of xerostomia on QOL. Time of diagnosis of HIV/AIDS was assessed. RESULTS A total of 78 (40.0%) subjects presented with xerostomia. Xerostomia was associated with female gender, low amount of saliva perceived (p ≤ .01), difficulty in swallowing food (p ≤ .05), and showed to have a negative impact on QOL as measured by OHIP-14 (p ≤ .01). CONCLUSION Xerostomia was frequent and showed to have a negative impact on the QOL of PLWHA.

Abstract
OBJECTIVES The aim of this study was to evaluate the association between metabolic control and oral health of adolescents with type 1 diabetes mellitus (DM1). STUDY DESIGN A case-control epidemiologic study was performed on adolescents allocated between 2 groups: DM1 group composed of 51 with DM1, and control group composed of 51 without diabetes. In the DM1 group, metabolic control data were observed (glycosylated hemoglobin (GHb) and capillary glucose), whereby GHb < or =8.0% was considered to indicate good metabolic control (DM1-A) and >8.0% poor metabolic control (DM1-B). Oral mucosal abnormalites, Community Periodontal Index (CPI), and decayed, missing, and filled (DMF) index were documented. Salivary flow was evaluated by means of stimulated saliva collection (SSFR). RESULTS Glycosylated hemoglobin values of < or =8.0% (DM1-A) were observed in 17 (24%) and >8.0% (DM1-B) in 34 (76%) of the subjects. The average DMF indexes were 1.5 (control) and 3.3 (DM1-group) (P < or = .05). The average CPIs were 0.2 (control), 1.4 (DM1-A), and 2.0 (DM1-B) (P < or = .05). Average SSFRs were 0.997 (DM1-A), 0.903 (DM1-B), and 1.224 (control) mL/min. CONCLUSIONS Oral health of adolescents with DM1 was impaired regardless of metabolic control.

Abstract
Celiac disease is a chronic intestinal disease caused by intolerance to gluten associated with poor digestion and absorption of the majority of nutrients and vitamins, which may affect both developing dentition and oral mucosa. The aim of this study is to make a brief review of the literature about celiac disease and to report on a clinical case, showing the impact it may have on the general and oral health. A 39-year-old woman reported the presence of diarrhea, nauseas, flatulence, colic, difficulty with falling asleep, lack of appetite and loose of 18 Kg in the last two years. She also noted the appearance of symptomatic lesions in the mouth. These lesions had a mean duration of a month and occurred in any region of the oral mucosa, particularly on the tongue. Multiples ulcerations were found in the sublingual caruncula region, at the vestibular fornix and at the lingual apex. Topical treatment was instituted for the oral lesions with immediately relief of the symptoms. The diagnosis of celiac disease was established by means of medical clinical exam, biopsy of the small intestine, and by the presence of specific antibodies in the blood. The patient has been instructed to follow a gluten-free diet. Multiprofessional action with the involvement of a gastroenterologist and other health professionals, such as dentists, is important for diagnosing the disease and guiding the patient with celiac disease to achieve a good quality of life.
