title: Clinical outcomes of peri-implantitis treated with bone substitute and resorbable membrane: a literature review with a systematic approach

description: ABSTRACT Objective: The objective of this review was to evaluate the outcomes of the treatment of peri-implant defects, using Guided Bone Regeneration. Methods: A literature search was performed based on the PICO methodology in the PubMed/Medline, SciELO, Lilacs electronic databases, CAPES periodicals and the Cochrane Library. We included studies using bovine mineral matrix, associated to a collagen membrane for the treatment of peri-implantitis by Guided Bone Regeneration. Results: Of 1,163 studies, 10 were included in this review after applying the evaluation criteria. A total of 269 implants were treated in 260 patients. The follow-up period ranged from 6 to 48 months. The studies evaluated outcome in terms of reduction in probing depth, gain of clinical attachment and healing of the bony defect. Due to the heterogeneity of the studies, it was not possible to perform meta-analysis. Conclusion: Treatment of peri-implant lesions with Guided Bone Regeneration is a viable modality of treatment, providing reduction in bleeding on probing, as well as gain of clinical attachment. Complete filling of the defect is, however, an unpredictable result.

title: Investigation of the psychological factors associated with fissured tongue

description: ABSTRACT Objective: This study aimed to investigate the correlation between FT and anxiety. Methods: The sample consisted of 95 participants categorized into two groups: a) G-FT, 48 patients with FT and b) CG, 47 healthy participants. All patients were submitted to complete oral and dermatological examinations. The anxiety levels were measured using the State-Trait Anxiety Inventory (STAI). A p-value of &lt; 0.05 was considered significant. Results: Fourteen (30%) patients reported awareness of having FT and 9 (64%) were women. Symptoms like burning feeling were reported by 3 (6%) only patients, all of then women. None of the control group patients presented these symptoms. In both groups, control and FT, the average scores of trait-anxiety were slightly higher than state-anxiety. There were no statistically significant differences between the FT and the control group related to the state-anxiety (p=0.724) and the trait-anxiety (p=0.680) scores. Study limitations: This study was limited by the number of subjects. Conclusion: Although moderate state-anxiety and trait-anxiety scores were determined, anxiety, as an environmental factor may not play a significant role in the development of FT. Considering FT as a multifactorial disease, probably a genetic component is necessary for expression.

title: Does hypersensitive teeth show pulp inflammation?

description: ABSTRACT Objective: This study investigated the presence of inflammatory response in the dental pulp of rats showing hypersensitive dentin, induced by erosive episodes. Methods: Sixteen Wistar rats were fed with commercial sucrose-free pellet diet for 12 hours; whereas the food was removed during the remainder of the day, and the animals received mineral water or a lemon-based sucrose-free soft drink, according to the group to which they belonged. Eight animals consumed the soft drink to induce hypersensitivity, while the other 8 animals received mineral water (control). After six weeks, the animals were euthanized, the mandible was removed and subjected to a median incision in the sagittal plane, to obtain right and left hemimandibles. The slides stained with hematoxylin-eosin were analyzed using light microscopy. Results: Histological evaluation of the control and experimental groups revealed no inflammatory process in the pulp tissue, and the presence of inflammatory cells, such as lymphocytes, plasma cells, eosinophils and macrophages, was not observed. In addition, there was no edema or dilated and congested blood vessels. The Mann-Whitney test showed no significant difference (p = 1.000) between the experimental and the control groups. Conclusion: In the animal model used, dentin hypersensitivity does not trigger dental pulp inflammatory response.

title: Candida on oral cavity of pediatric individuals with ALL and its susceptibility to nystatin and amphotericin B

description: ABSTRACT Objective: The aim of this study was to evaluate the prevalence of Candida colonizationon oral cavity of pediatric individuals with acute lymphocytic leukemia (ALL) and its susceptibility/resistance to nystatin and amphotericin B. Methods: This was a cross sectional study with observational, descriptive and analytic approach. Saliva was collected from40 individuals diagnosed with ALL and from40 healthy subjects, as a comparative group, matched by age and gender with ALL group. The mean age for both groups were 8 years-old. The isolation and identification of the Candidaspecies were performed using the CHROMagarCandidaTM and confirmed by polymerase chain reaction. The samples were subjected to antifungal susceptibility by microdilution assay for nystatin and amphotericin B. Salivary alterations and chemotherapy-induced oralmucositis were evaluated using modifiedOral Assessment Guide. Results: The positivity to Candida was higher inALL individuals (32.5%,13/40)than in a comparative group(2.5%, 1/40) (p&lt;0.001). Candida albicans was the most prevalent strain (86.6%). The mucositis was directly associated with positive Candidacolonization (p=0.017) in the ALL group but not related with salivary alterations (p= 0.479). Six strains of C. albicans (54.5%), on ALL group, were resistant to nystatin and all strains were not susceptible to amphotericin B. Conclusion: Candida colonization was associated with ALL condition and with oral mucositis in these individuals. C. albicans was the prevalent strain and most samples were resistant to antifungal agents tested, nystatin and amphotericin B.

title: CELL growth and viability analysis in poli membranes (L-lactic acid-CO-glycolic acid): an in vitro study

description: ABSTRACT Objective: Performing an in vitro evaluation of the biological effects on cell growth and viability of fibroblasts in PLGA membranes with and without simvastatin. Methods: Two groups of resorbable synthetic polymeric membranes were used: PLGA, with and without simvastatin, cut into a suitable format to fit to 24 thermometric wells. Fibroblasts were grown on resorbable membranes and evaluated for proliferation and viability at 24, 48 and 72 hours after the beginning of cultivation, being the tests performed in triplicate. For the cell growth analysis, the Trypan blue exclusion method was applied, while cell viability was observed by the MTT test. The results were statistically analyzed applying the Two-Way ANOVA, followed by the Bonferroni test, with 95% confidence interval and P value smaller than 0.05 was accepted as statistically significant. Results: Statistical difference (p &lt;0.01) was seen between the control group (2.16x104 ± 0.51 cells) and the PLGA group with simvastatin (1.58x104 ± 0.36 cells) in the 48-hour period. After 72 hours, statistical differences (p &lt;0.001) were observed between the PLGA group with simvastatin (1.66x104 ± 0.49 cells) and the PLGA group without simvastatin (2.25x104 ± 0.2 cells) when compared to the control group (2.81x104 ± 0.33 cells) for cell proliferation. Statistical differences (p &lt;0.05) were observed between the control group (0.27 ± 0.05) and the PLGA group with simvastatin (0.21 ± 0.03). Likewise, a statistical difference (p &lt;0.001) was seen between the PLGA group without simvastatin (0.19 ± 0.02) and the control group after 24 hours. In the 48 – 72-hour period, statistical differences (p &lt;0.001) were observed between the control group (0.36 ± 0.09 and 0.55 ± 0.05, after 48 and 72 hours respectively) and the PLGA group without simvastatin (0.26 ± 0.05 and 0.34 ± 0.07, after 48 and 72 hours respectively), as well as in the PLGA group with simvastatin (0.27 ± 0.04 and 0.31 ± 0, 04, after 48 and 72 hours respectively) for the cell viability test. Conclusion: The association of simvastatin to PLGA membranes had an inhibitory effect on fibroblast proliferation, as well as induced a reduction in cell viability. Thus, the use of PLGA along with simvastatin may assist in guided bone regeneration.

title: Methods for qualitative and quantitative analysis of pain and quality of life validated in Brazil: systematic review

description: ABSTRACT Objective: The need to quantify pain and quality of life (QoL) is essential for professionals considering their therapeutic approach. The goal of this review is to identify the methods to perform qualitative and quantitative analysis of pain and QoL validated in Brazil. Methods: Review by the LILACS, SciELO, MedLine and Google Scholar databases with the descriptors: methods, qualitative analysis, quantitative analysis, pain and quality of life. Inclusion criteria: articles published in Portuguese and in English in the period from 1996 to 2015. Exclusion criteria: incomplete texts, articles that did not address the subject of study and duplicate articles in the databases. Results: After applying the eligibility criteria, 27 articles were selected for reading, being that one article was excluded by presenting irrelevant result and another was excluded by duplication. From the 25 articles, one was published in 2015, three in 2014, one in 2013, three in 2012, five in 2011, two in 2010, three in 2009, four in 2008, two in 2004 and one in 1996. In relation to the studies, nine were clinical trials, 10 systematic reviews, five cross-sectional studies and one essay. Conclusion The most frequently methods applied are the VAS and the McGill’s Questionnaire, considering the multidimensional pain assessment. The most commonly used questionnaire to evaluate QoL is the SF-36. There is great difficulty to classify methods for assessing pain and QoL (qualitative or quantitative methods), since many authors report the same method when addressing the two interfaces.

title: Development of cleft children’s permanent canines

description: ABSTRACT Objective: Evaluating the development of the permanent cuspids in children from Paraíba with cleft lip and palate applying the Nolla and the Demirjian methods. Methods: A cross-sectional study using an inductive approach and applying a comparative statistical procedure and direct documentation research technique. The universe of the study consisted of children assisted at the orthodontic practice of the Brazilian Association of Dentistry - Paraíba Section. The sample comprised 72 pairs of panoramic radiographs of children with and without cleft lip and palate from the same gender and, age difference of up to 30 days, ranging from 5 to 13 years of age. The study has evaluated the development of 576 cuspids. The images were evaluated by three duly calibrated examiners concomitantly, and the calcification stages were determined by a consensus. The stages of the cuspids calcification were evaluated in the panoramic radiographs according to Nolla and Demirjian classifications. Results: The average of the calcification stage of teeth was correspondingly higher in the control group than in the case group, showing a development delay of the cuspid teeth in the cleft lip and palate patients. The lower cuspids were significantly more developed than the upper cuspids (p &lt;0.001). There were no significant differences between the sides. There was early tooth development in females but without significant difference. Conclusion: It was possible to note that patients with cleft lip and palate presented a delay in the development of the permanent cuspids when compared to non-cleft lip and palate patients, thus, reinforcing the importance of the individualization of the orthodontic planning.
