title: Analysis harmful health habits among patients with oral lesions

description: Objective It is proposed to identify the prevalence of smoking and drinking habits among patients diagnosed with oral lesions, as well as possible associated factors. Material and method Analytical study, retrospective character between patients assisted by University Dental Clinic in the area of Oral Diagnosis. Dental records were analyzed and histopathological reports of patients who performed the biopsy procedure between February 2010 to July 2012. The dependent variables – harmful habits - were built by information pertaining to smokers and current drinking habits or passed. SPSS software was 19.0. Descriptive and univariate analyses were conducted by the Pearson's Chi-square test (p≤0.05). The normality of sample was investigated by the Kolmogorov-Smirnov test and Shapiro-Wilk (p&lt;0 .05). Result Of the 125 patients attended at 110 evaluation period have been included. The presence of smoker and current elitist habits or past were identified in 42 (38.2) and 21 (19.1) patients, respectively. In univariate analysis the variables statistically significant (p ≤ 0.05) associated with the habit smoker were: sex, age, type of biopsy and histopathologic diagnosis. As for the elitist habit variables were: sex and type of biopsy. Conclusion Smoking and drinking habits have been or remain present in the life of a significant portion of individuals investigated who developed Oral lesions, being, yet, relevant with the synergy of both in the development of such injuries.

title: Evaluation of the pattern dimensions of cast-metal posts in uniradicular teeth

description: Introduction Accurate dimensions of cast-metal posts are relevant to the survival of dental prostheses. Objective The aim of this study was to verify if the dimensions of cast-metal posts accord with ideal clinical criteria. Material and method For the evaluation, 285 periapical radiographs, from a total of 80 teeth, were taken from the charts of patients that attended the clinics at the Dental School of the Federal University of Goiás, from March 2008 to October 2012. Only periapical radiographs of single-rooted teeth with post and core were included in the study. The radiographic evaluation was conducted with the assistance of a magnifying glass and a view box, in a room with low luminosity. The dimensions of the post and core were established with the help of a digital caliper, and the following measurements were considered: a) LR (Length Remnant); b) LP (Length Post); c) BS (Bone Support); d) DR (Diameter Root); e) DP (mesiodistal diameter post). The post and core were classified as acceptable or deficient by reference values with a margin of error of 0.2 mm. For descriptive analysis, the data were cataloged using SPSS software (version 17.0). Result With regard to the length of the post and core, only 26.25% and 43.75% of the post and core were classified as acceptable according to the two-thirds rule and fulcrum dental rule, respectively. With regard to the mesiodistal diameter of the post and core, 55% were classified as acceptable. Conclusion Within the limits of this study, it can be concluded that the cast-metal posts evaluated do not accord with the ideal clinical criteria.

title: Evaluation of surface hardness of glass ionomer reinforced cements by carbon nanotubes

description: Introduction Glass ionomer cements (GIC) are materials with low tensile and shear bond strength and therefore contraindicated in areas subjected to high occlusal stress loads. Aim To evaluate the effect of incorporation of carbon nanotubes in GICs, conventional or indicated for the Atraumatic Restorative Treatment (ART), through the superficial microhardness test. Material and method Forty-eight specimens were prepared and divided into 4 groups according to the type of GIC (n=12): conventional or high viscosity, embedded or not with 2% carbon nanotubes (CN): (A) Vidrion R, (B) Vidrion R + 2% CN, (C) Vitro Molar and (D) Vitro Molar + 2% CN. The specimens were inserted into plastic molds with Centrix syringe and stored in deionized water for 24 hours. After polishing, the superficial hardness was performed with a Knoop indenter. Five indentations were made on each specimen, with distance of 100 micrometers between indentations. Result The average hardness values were 58.96 ± 8.29 (A) 34.81 ± 5.78 (B) 4.91 ± 60.84 (C) 41.97 ± 5.45 (D). ANOVA detected significant difference for the two varibales, material (p=0,016) and CN inclusion (p&lt;0,0001). Tukey test revealed that the groups A and C were statistically similar (p&gt;0.05), while the B and D groups showed significant differences (p&lt;0.05). When comparing the incorporation or not of factor CN, there was significant difference between groups A and B and between C and D groups (p&lt;0.05). Conclusion The incorporation of CNTs negatively influenced the values of surface hardness for the two types of GIC used.

title: Evaluation of periodontal conditions and oral hygiene in school children with neuropsychomotor disorders

description: Introduction Caries and periodontal disease are problems frequently affecting patients with disabilities. Objective In this study we aim to evaluate the periodontal conditions and the oral hygiene in students with neuropsychomotor disorders enrolled in a rehabilitation center. Method Data collect was based in interview with the responsible and the scholar's clinical exam to register the plaque index and the bleeding index. After the clinical exam were performed professional prophylaxis, oral hygiene orientation and explanation of doubts. Result The sample consisted of 41 students with neuropsychomotor disabilities, with ages among 7 and 14 years, 20 females (48.8%) and 21 males (51.2%) with a mean age of 10.8 years. Most patients had the figure of the mother as primary caregiver (85%). It was observed that 71% of students need help in performing oral hygiene and nearly 40% of caregivers had difficulty doing it, in most of the cases because the patient "did not open his mouth". Almost the totality of the students doesn't use dental floss. It was also found that 87.2% had gingival bleeding and 84.7% had the plaque index greater or equal to 2. Conclusion It was concluded that disabled students included in this study had bad periodontal conditions and poor oral hygiene. It shows the need of preventive programs to guide themselves and the caregivers, seeking for effectiveness of oral hygiene.

title: Development of caries adjacent to composite restorations after exposure to dentifrices with different fluoride concentrations

description: Objective To evaluate the development of recurrent caries after exposure to fluoride dentifrices with different concentrations. Material and method: 48 samples of bovine incisors (4x4mm2) were exposed to pH cycling for 7 days before the preparation of the cavities (2mm deep). The samples were restored with a microhybrid resin composite. Then, the samples were exposed to thermal cycling (350 cycles) and they were randomly allocated into 4 treatment groups (n = 12): Group A - non-fluoridated dentifrice (negative control); Group B - 500 ppm dentifrice; Group C - 750 ppm dentifrice; group D - 1100 ppm dentifrice (positive control). The samples were treated with solutions of each dentifrice (9.6 ml water/1.6 g dentifrice) for 60 seconds and then were immersed in demineralizing (3 h) and remineralizing (2 h) solutions 3 times a day. Next, the samples were immersed in a remineralizing solution for 18 hours. Then, the blocks were sectioned for examination of the length of the outer caries lesion, using polarized light microscopy. The ANOVA parametric test complemented by the Tukey test with a confidence level of 95%, were used in the statistical analysis. Result: A smaller lesion length was observed in the group treated with the fluoride concentration of 1100 ppm F, but there were no differences between toothpastes with fluoride concentrations of 500 and 750 ppm F. Conclusion: The use of fluoride dentifrices (1100 ppm) reduces the development of caries adjacent to dental restorations.

title: Evaluation of signs and symptoms of temporomandibular dysfunction and its relation to cervical posture

description: Introduction The temporomandibular disorders (TMD) can cause general changes in mandibular movements due to changes in muscle and joint conditions. Objective To evaluate the signs and symptoms of temporomandibular disorders and its relationship to cervical posture. Material and method Cross-sectional and descriptive study with a quantitative approach conducted at the University of Fortaleza from August 2011 to April 2012, where 23 participants with temporomandibular disorders answered the questionnaire (PorDTMmulti) about the signs and symptoms of the condition and were photographed for measurement of head posture evaluation and cervical lordosis. Result The average age of participants was 34.7 years. The average cervical angle was 29.7 degrees and 3.6 cm of cervical lordosis. Headache (82.6%), muscle pain (78.3%) and noise in the temporomandibular joint (73.9%) were the most commonly reported signs and symptoms by the sample. The ear pain (26.1%) was the least reported symptom. Most participants reported signs and symptoms from both sides. No correlation between the measurement of cervical angle and the sings, symptoms and difficulties surveyed was noted. A moderate correlation between the extent of cervical lordosis and the difficulty in opening the mouth (p=0.03; r= –0.4) was found. Conclusion It was demonstrated that in the study population, among the signs and symptoms of TMD, headache was the most cited, and the greatest difficulty presented by participants about the dysfunction was chewing. It was revealed further correlation between the difficulty opening the mouth and cervical lordosis.

title: Correlations between supra- and subgingival clinical parameters in smokers and individuals who have never smoked

description: Introduction Smoking is a risk factor for prevalence, severity and progression of periodontal disease and appears to suppress marginal periodontium inflammatory response. Purpose To correlate Visible Plaque Index (VPI) and Gingival Bleeding Index (GBI) in smokers and never-smokers, as well as GBI and bleeding on probing (BOP ) in these groups. Material and method We used baseline data of one quasi-experimental study in which 11 smokers and 14 subjects who never smoked were submitted to clinical periodontal examinations between September 2010 and October 2011. Result The correlation between VPI and GBI was positive for both groups, it was strong and statistically significant in subjects who had never smoked and moderate in smokers. Regarding GBI and BOP correlations were moderate for smokers and weaker for individuals who had never smoked. Conclusion Smokers have lower strength correlation between VPI and GBI compared to individuals who had never smoked resulting in a less pronounced marginal gingival bleeding.
