RESUMO

Aim: To derive and validate a short version of the Oral Health Impact Profile (OHIP) in Spanish to measure oral health quality of life (OHRQoL) for subjects wearing fixed orthodontic appliances. Methods: Cross-sectional study (data for sensitivity to change analysis were collected longitudinally). The data of 400 subjects (27.34 years, SD 11.66 years, 231 women, and 169 men) were used to develop a short-form instrument, and the data of 126 other subjects (25.95 years, SD 12.39 years, 62 women, and 64 men) were used for its validation. The original OHIPs were translated into Spanish using an iterative forward-backward sequence. After face and content validity were evaluated by an expert committee, an exploratory factorial analysis (EFA) was used to derive the Spanish short-form instrument (OHIP-S14 Ortho). To validate the OHIP-S14 Ortho, validity (content validity assessed by EFA, construct validity assessed by confirmatory factor analysis (CFA), discriminative validity assessed by the Kruskal-Wallis test, and reliability (internal consistency assessed by Cronbach's α test-retest, and inter-observer reliability assessed by correlation coefficients) were evaluated. Sensitivity to change and usefulness of the scale were also evaluated. Results: The OHIP-S14 Ortho included only six of the items in Slade´s original OHIP-14 short-form. A two-factor structure with adequate discriminative validity was found. High internal consistency (α=0.912), excellent inter-observer (Lin's correlation=0.97±0.011; rho= 0.97), test-retest agreement (Lin's correlation=0.80±0.059) and adequate sensitivity to change were also found. Conclusions: The OHIP-S14 Ortho is a valid and reliable instrument to measure OHRQoL in Spanish-speaking patients with fixed orthodontic appliances

RESUMO

Aim: This study aimed to compare the microbiological potential and gustatory perception of essential oils (EO) mouthrinses containing and not containing alcohol. Methods: Twenty healthy adult volunteers rinsed with 10mL of the following test solutions: EO with alcohol, EO without alcohol, or a control solution (saline solution with mint essence). A washout period of at least seven days was adopted after a single-use protocol of the respective solution. All participants used all three tested substances. Antimicrobial potential was assessed by counting salivary total viable bacteria both before and after each rinse. Gustatory perception was evaluated using the Visual Analogue Scale (VAS). Multiple comparisons were performed with the Wilcoxon test, using Bonferroni correction. Results: Both EO solutions presented a higher antimicrobial potential in comparison to the control solution (p<0.017). However, no significant difference in antimicrobial potential was observed between EO containing or not containing alcohol (p=0.218). VAS of EO with alcohol (median: 2.7) was similar to control solution (median: 1.6) (p=0.287). A better gustatory perception was observed of the EO without alcohol (median 7.6) when compared to the control solution (p<0.0001). When EO groups were compared, EO without alcohol also demonstrated a significantly better gustatory perception (p=0.001). Conclusion: Mouthrinse containing EO without alcohol presented a better taste perception when compared to the EO with alcohol, but no difference was observed in the antimicrobial potential of both EO solutions after a single rinse protocol

RESUMO

Aim: Evaluation of the reliability of 3D computed tomography (3D-CT) in the diagnosis of mandibular fractures. Methods: A cross-sectional, quantitative and qualitative study was carried out, through the application of a questionnaire for 70 professionals in the area of Oral and Maxillofacial Surgery and Radiology. 3D-CT images of mandibular fractures were delivered to the interviewees along with a questionnaire. Participants answered about the number of traces, the region and the type of fracture. The correct diagnosis, that is, the expected answer, was based on the reports of a specialist in oral and maxillofacial radiology after viewing the images in the axial, sagittal and coronal sections. The resulting data from the interviewees was compared with the expected answer and then, the data was analyzed statistically. Results: In the sample 56.9% were between 22 and 30 years old, 52.8% were oral and maxillofacial surgeons (OMF), 34.7% were residents in OMF surgery and 12.5% OMF radiologists. Each professional answered 15 questions (related to five patients) and 50.8% of the total of these was answered correctly. Specialists in Oral and Maxillofacial Surgery and Traumatology correctly answered 53.9%. Interviewees with experience between 6 and 10 years correctly answered 58.2%. In identifying fracture traces, 46.1% of the questions were answered correctly. In terms of location, 5.6% of interviewees answered wrongly while 14.2% answered wrongly regarding classification. Conclusion: 3D computed tomography did not prove to be a reliable image for diagnosing mandibular fractures when used alone. This made necessary an association with axial, sagittal and coronal tomographic sections

RESUMO

Aim: To evaluate the prevalence and predisposing factors for hypomineralization of second molars in children in primary dentition. Methods: A questionnaire was applied to parents to analyze predisposing factors and to assist in the diagnosis of hypomineralization in children between 2 and 6 years old, followed by an intraoral examination based on indices of non-fluorotic enamel defects in the primary dentition, according to the "Modified Index DDE" to determine demarcated opacity and HSPM presence / severity index to assess hypomineralization. Children from public and private schools were dived into two groups: if they presented HSPM-Group 1 (G1) and if they did not have HSPM-Control group (CG). Results: The most frequent predisposing factors associated with the child were Illness in the first year of life (X2= 6.49; p=0.01) and antibiotic use in the first year of life (X2= 41.82; p= 0.01). The factors associated with the mother were hypertension (X2= 9.36; p=0.01), infections during pregnancy (X2=14.80; p=0.01) and alcohol consumption during pregnancy (X2=97.33; p=0.01). There was a prevalence of 3.9% of HSPM in 14 children, with statistical difference regarding gender (X2 = 4.57; p <0.05), with boys presenting a higher frequency. In G1 hypomineralization was of the type with demarcated opacity, with more prevalent characteristics the yellowish spot, with moderate post-eruptive fracture and acceptable atypical restorations. All lesions were located in the labial region with 1/3 of extension. Conclusion: The prevalence of HSPM in children between 2 and 6 years old was 3.9%, with a predominance in males, with tooth 65 being the most affected. There was an association between HSPM and infection in the first year of life, as well as the use of antibiotics and sensitivity in the teeth affected by the lesion. There was an association between HSPM and hypertension, infection and mothers' alcohol use during pregnancy

RESUMO

Grade C periodontitis in youngers is characterized by a severe form of periodontitis, and IL10 rs6667202 single nucleotide polymorphism (SNP) has been described as an important feature in this disease etiology. Aim: This study aimed to evaluate, in vivo, the functionality of IL10 rs6667202 SNP on IL-10 gingival fluid levels. Methods: Thirty patients with Perio4C were selected, 15 with the IL10 AA genotype (rs6667202) and 15 with AC/CC genotypes. The gingival fluid was collected from two sites with probing depth ≥ 7 mm and bleeding on probing, and two healthy sites. The IL-10 concentration was determined by Luminex/MAGpix platform. Results: In deep pockets, the IL10 AA genotype presented a lower concentration of IL-10 when compared with AC or CC genotypes (p<0.05). In shallow pockets, no difference between groups was seen (p>0.05). Conclusion: IL10 rs6667202 SNP decreases the production of IL-10 in crevicular fluid, potentially affecting this disease progression

RESUMO

Aim: In this cross-sectional study, we evaluated the oral hygiene habits, oral health conditions, and the perception about the influence of oral health conditions on the physical performance of youth and professional volleyball and soccer athletes. Methods: A total of 96 male athletes participated: 48 volleyball players (25 youth and 23 professional players); and 48 soccer players, of whom 22 were youth, and 26 were professional players. We analyzed the oral hygiene and oral health condition (daily toothbrush, flossing, mouthwash, dental plaque, orthodontic treatment, dental/facial trauma, temporomandibular dysfunction, malocclusion, and the athletes' perception about the influence of oral health conditions on the physical performance (yes or no)). Comparisons were made between the youth and professional athletes for each sport (volleyball and soccer). According to each variable, we applied the Chi-square, Fisher's Exact, and Mann-Whitney tests. Results: For soccer athletes, we found significant differences between youth and professionals for: flossing (p=0.014), orthodontic treatment (p=0.028), dental/facial trauma (p=0.041), and the athletes' perception about oral health and physical performance (p<0.001). Considering the category (youth and professional) regardless of the type of sport, we found significant differences for dental plaque (p=0.024) and dental/facial trauma (p=0.005). According to the sport (volleyball and soccer), independent of the category, we found significant differences for daily brushing, dental/facial trauma (p=0.005), and the athletes' perception about oral health and physical performance (p=0.006). Conclusion: We concluded that the surveyed athletes had good oral health and believed that oral health can influence sports performance

RESUMO

Minimally invasive dentistry is based on conservative techniques for the treatment of initial caries lesions, the so-called white spot lesions. One of the conservative maneuvers includes the use of enamel resin infiltrant: a low viscosity material that penetrates the enamel pores to stop lesion progression. Aim: Therefore, this case report aimed to describe the clinical case of a 28-year-old female patient under routine consultation, in which a radiographic examination showed the presence of two incipient caries lesions in the left upper premolars. Methods: The application of a resin infiltrating agent (Icon®, DMG ­ Hamburg, Germany) was chosen as treatment to stop caries lesions progression. Conclusion: The use of this conservative technique can be considered a promising approach for the prevention of dental tissue wear, and the resin infiltrant is considered an effective material

RESUMO

Aim: To investigate restorative decisions made by dentists and to examine what demographic characteristics are associated with the decisions for managing approximal and occlusal lesions. Methods: A questionnaire was randomly sent to 900 Palestinian dentists. It noted the demographic details of the dentists and the years of experience. The questionnaire evaluated the respondents for their treatment decisions regarding approximal and occlusal carious lesions. The data was analyzed using the IBM SPSS statistics for windows. The associations between gender and years of experience of the respondents and their restorative decisions were assessed. Results: The response rate was 58.2%. For occlusal carious lesions, 93.9% of the respondents would postpone operative treatment until the lesion was in dentine (grade 3 to 5). For approximal lesions, intervention was deemed appropriate by 92.6% of the respondents when there was radiographic evidence of a carious lesion reaching the DEJ or deeper. Around 53% preferred to prepare approximal lesions according to the traditional principles of cavity preparation. For both approximal and occlusal lesions, the participants opted for resin composites. Statistically, there was a significant association between the restorative decisions with the years since graduation and gender. Conclusion: The study showed variations between the treatment decisions of Palestinian dentists. The subjects chose conservative treatment plans but still adhered to traditional learned practices especially when cavity preparation for approximal lesions was concerned. The years since graduation and gender played a significant role in the choice of treatment opted for. Resin composites seemed to be a popular choice for treatment

RESUMO

Aim: This study evaluated, by the application of questionnaires, the impact of the COVID-19 pandemic on the clinical routine and inspection by the competent authorities, on the flow of patients in the office, as well as on possible changes in Endodontic treatment costs and the amounts charged to patients. Methods: This cross-sectional study was conducted from May 2nd, 2020 to May 6th, 2020, using an online questionnaire with a convenience sample. The inclusion criterion was professionals who perform endodontic treatments in daily clinical practice and who professional setting is private practice. The questionnaire brought questions about the impact on costs and the amount charged to the patient. Results: A total of 1042 questionnaires were answered from all the different states of Brazil, by professional who usually perform Endodontic treatment, and who is working in private practice. A total of 1010 (96.9%) respondents affirm it was necessary to modify the protective equipment in endodontic treatment due to pandemic and longer intervals between appointments was cited by 922 (88.5%), economically affecting the dental practice. There was no association between routine changes and economic impacts with gender, professional experience, area of residence or education level. Conclusion: In conclusion, most dental professionals recognized changes in the routine of endodontic treatment during the COVID-19 pandemic. They have a perception of increase in endodontic costs, and reduction in the volume of patients

RESUMO

There are various instruments to measure attitudes toward persons with disabilities (PwD). The Multidimensional Attitudes Scale (MAS) toward PwD is a three-dimension scale with good psychometric properties; the Spanish version has been validated with a four-factor structure. Aim: To examine the factor structure of a cross-cultural adapted version of the Spanish MAS towards deaf persons in a sample of Chilean dental students. Methods: This cross-sectional study involved five Chilean public health experts that reviewed the scale for obtaining a preliminary version of a 30-item modified MAS towards deaf persons; a pilot with 15 dental students was performed, and a final sample composed of 311 students was included. For the exploratory factor analysis (EFA), maximum likelihood estimation (ML) for determining the number of factors and parallel analysis (PA) was used, with Oblimin for the rotation method. Cronbach's alpha was used to assess reliability. The root mean square error of approximation (RMSEA), comparative fit index (CFI), incremental fit index (IFI), goodness of fit index (GFI), Tucker-Lewis fit index (TLI-NNF) and root mean square of residuals (RMSR) were used to assess model fit. Results: All items had a normal distribution with the exception of items 7 and 10. The four-factor structure without item 10 in this EFA presented an adequate Cronbach's alpha (>0.83), suggesting acceptable reliability. RMSEA, TLI-NNFI, RMSR, GFI and CFI indices suggested a good fit of the model and were consistent with the literature. Conclusion: The Spanish modified version of the MAS towards deaf persons has a four-factor structure, which in consistent with a previous version of the MAS

RESUMO

Oral squamous cell carcinoma (OSCC) is one of the most well-known malignancies that affect the human population worldwide. The early diagnosis and early intervention of OSCC help improve the survival rate of the patients. The tumour free surgical margins are a positive prognostic factor for recurrence-free survival. The molecular markers can be used to detect the tumour free surgical margins. Aim: The aim of the study is to evaluate the expression of p53 & Cyclin D1 marker in resected surgical apparently clear margins and to correlate the p53 & Cyclin D1 expression with clinicopathological characteristics and patient outcome. Methods: The study population included retrospective cases of OSCC with apparently clear margins (2017-18) n=10 and Clinicopathological variables relevant to survival analysis were recorded. Finally, two margins were selected from each case, a total of 20 margins were included in this study. Paraffin-embedded wax blocks retrieved and tissue sections were made. Expression of cyclin D1 and p 53 was assessed by the immunohistochemical staining procedure Results: Positive expressions Cyclin D1 in 40% of mild dysplasia margins and 60% in clearance adequate margins were present. p53 expression was seen in 16% of mild dysplasia margins and 84% in clearance adequate margins. The expression of p53 and Cyclin D1 molecular markers are noted in the basal & parabasal layer of epithelium. Conclusion: Molecular markers could play a more reliable method for the assessment of dysplasia at the margins

RESUMO

Aim: To evaluate the effects of an intervention for the prevention of obesity on the prevalence of dental caries disease in Spanish children. Methods: Two cities participated intervention study nested in a cohort IDEFICS (Identification and prevention of dietary and lifestyle induced health effects in children and infants): Huesca, where there was a 2-year intervention, which encouraged less sugar consumption; and Zaragoza (control). The prevalence of caries was evaluated by examining the 1st permanent molars in the 7-11 age range, using the ICDAS (International Caries Detection and Assessment System). These teeth erupt at 6 years of age and at the baseline (2007-2008) were free of caries because they were not present in the oral cavity. As outcomes, white spots were selected, combining the ICDAS criteria 1 and 2, and untreated caries, combining criteria 4, 5 and 6. Their association with socioeconomic variables, BMI (Body Mass Index), frequency of sugar intake, sex and parents' perceptions of their children, was investigated. To do so, the chi-square test was applied (p<0.05). Results: The sample consisted of 281 children. The prevalence of white spots and untreated caries was higher in Huesca, despite the intervention. There was no association between the outcomes and the variables studied (p>0.05). Conclusion: The intervention for the prevention of obesity did not exert any association with the prevalence of caries in Spanish children

RESUMO

Aim: The present study sought to investigate dental caries experience and its association with sociodemographic, postnatal and breastfeeding variables in children in the agerange from 6 to 71 months of age, in the Xingu Indigenous Park, Mato Grosso, Brazil. Methods: This was an analytical cross-sectional study that used secondary data pertaining to 402 indigenous children of the Low, Middle and Eastern Xingu regions, who participated in the Oral Health Epidemiological Survey in 2013. The dependent variable was dental caries, dichotomized by the median (dmf-t≤1 and dmf-t>1). The data of independent variables were obtained by means of instruments of the Local Health Information System of the Xingu Indigenous Special Sanitary District (DSEI). Raw analyses were performed to test the association of the independent variables with the dependent variable. The variables were tested in the multiple logistic regression model. Results: The mean value of the dmf-t index was 2.60 and the prevalence of affected children was 51%. In the multiple analysis, only children older than 36 months (OR: 6.64; CI95%: 4.11 to 10.73) and those that were breastfed for a longer period of time (OR: 1.88; CI95%: 1.16 to 3.02) showed significant association with the dmf-t>1 index. Conclusion: Childhood dental caries among indigenous children was associated with age and breastfeeding prolonged for over 26 months, therefore, pointing out the need to offer dental follow-up care at earlier ages

RESUMO

Aim: To evaluate orthodontists' knowledge and clinical practices regarding the treatment of patients with HIV/AIDS. Methods: Cross-sectional study performed with 655 Brazilian orthodontists based on a previously calculated sample size. Self-administered questionnaires were sent to orthodontists to collect information on knowledge and clinical conduct regarding the care of patients with HIV/AIDS. The study evaluated the awareness of possible risk factors for contamination, oral manifestations of HIV, need for more information on the care of HIV-positive patients, whether orthodontic treatment is indicated in HIV-positive patients, and whether they had knowingly performed orthodontic treatment in HIV-positive patients. Simple regression models were adjusted, and crude Odds Ratios estimated the associations with 95% confidence intervals. The variables with P < 0.20 in the crude analysis were tested in multiple logistic regression models, and those with P ≤ 0.05 were maintained in the final model. Magnitudes were estimated by adjusted Odds Ratios values, with 95% confidence intervals. Results: Orthodontists who were aware of the oral manifestations of HIV/AIDS, those having work experience of more than 20 years, and those who believed that orthodontic treatment could be indicated for these patients were 3.30 (1.79-6.10), 2.74 (1.36-5.52) and 1.92 (1.13-3.24) times more likely to perform orthodontic treatment in HIV-positive patients, respectively. Most orthodontists (92.9%) reported they needed to obtain more information about orthodontic care in patients with HIV/AIDS. Conclusion: Although orthodontists reported feeling able and qualified to provide dental care to patients with HIV/AIDS, gaps in their knowledge need to be addressed with further training

RESUMO

Aim: Dental imaging has been widely used for diagnosis in dentistry. However, dental X-ray may induce cytotoxicity leading to apoptosis in oral mucosa cells. The present study aimed to observe the maturation pattern of buccal and gingival cells after exposure to X-ray radiation from analog/digital panoramic scanning and cone beam computed tomography (CBCT). Methods: The research samples were 40 subjects who fulfilled the inclusion and exclusion criteria. The subjects were divided into the exposed (patients who received analog/digital panoramic radiography or CBCT) and controlled (patients who had no radiography examinations) groups, with 10 subjects in each group. Exfoliative cytology smears were obtained from buccal mucosa and gingiva before exposure (or on day 0 for the control group) and 10 days later. The cells were stained with the Papanicolaou method. Then, the superficial, intermediate, and parabasal cells were counted in each glass slide. Results: No significant differences (p > 0.05) were observed among all cell types between day 0 and 10 in the control group. Meanwhile, after exposure to three kinds of radiography examinations, the frequency of intermediate cells in buccal mucosa and gingiva increased (p < 0.05), but that of superficial cells decreased (p < 0.05) significantly. No significant difference was found in the parabasal cells (p > 0.05). The frequency differences between intermediate and superficial cells showed no significant difference between the buccal mucosa and gingiva. Conclusion: Analog/digital panoramic radiography and CBCT exposure can induce cytotoxicity by altering the maturation pattern of buccal mucosa cells and gingiva, so it is strongly recommended to only perform these procedures if necessary and avoid repeated exposure to the same patient

RESUMO

Aim: to evaluate the intra and inter-device reliability of two intraoral spectrophotometers in measuring the Commission Internationale de l'Éclairage (CIE) L*a*b* color coordinates and to compare the color difference (ΔE) between both devices. Methods: the central region of the labial surface of the maxillary central incisor of 31 participants was measured twice by each of the devices (VITA EasyShade and Degudent Shadepilot) by one examiner. CIE L*a*b* color coordinates were obtained for all teeth and ΔE was measured and compared. Intraclass correlation coefficient (ICC) and Mann-whitney U test were used to analyze the data (p<0.05). Results: inter-device reliability ICCs in measuring CIE L*a*b* color coordinates ranged between 0.08-0.49 with significant difference between devices only concerning the b coordinate (p<0.05). While intra device reliability ICCs ranged between 0.86-0.89 for VITA EasyShade and 0.81-0.86 for Degudent Shadepilot. The mean ΔE for CIE L*a*b* color coordinates of VITA EasyShade was 3.61 (±1.93) compared to 3.60 (± 1.45) for Degudent Shadepilot with insignificant difference between both devices (p>0.05). Conclusions: high intra device reliability in measuring CIE L*a*b* color coordinates was achieved particularly of Vita EasyShade, and both devices had clinically acceptable color difference (ΔE <3.7) however, inter device reliability was low to moderate. Consequently, the same spectrophotometer should be used throughout the steps of performing any tooth- colored restoration

RESUMO

Aim: The mandible is regarded as a frequently fractured bone in patients who present with maxillofacial trauma accounting for almost 15.5% to 59% of all facial fractures. Managing condylar trauma has remained to be a point of contention amongst experts, regardless of the advances in surgical modalities and methodologies, and the treatment plan is often determined by the preference and the experience of the surgeon. There exist various approaches in the literature, each with its own specific benefits and drawbacks. With this study, we aimed to evaluate the prevalence of post-operative complications in patients who experienced ORIF by means of the retromandibular approach, by comparing the outcomes of one group having undergone transparotid surgery, with another that underwent retroparotid surgery. Methods: An experimental trial was undertaken. Convenience sampling was done from among the cases of condylar neck and base fracture visiting the department of OMFS, Dow University of Health Sciences from January 2017 to December 2019. An overall 26 patients were divided into 2 groups of 13 members each; one was managed using Open Reduction Internal Fixation (ORIF) by means of a retromandibular transparotid approach while the other group was treated with ORIF by means of a retromandibular retroparotid approach. A 6 month follow-up was done to assess range of active motion, occlusion, and complications such as deviation/deflection, neural injury, infections, sialocele, salivary fistulae and Frey's syndrome in both groups. Results: There was no statistically significant difference between the two groups in terms of inter-incisal opening, right and left lateral movements, or protrusion. One patient in the retroparotid group had deviation on mouth opening (7.69%), while one in the transparotid group reported with infection (7.69%), and 2 developed post operative seromas (15.38%). None had persisting facial nerve palsy at 6 months. Conclusion: We find no significant disparity between the 2 approaches at a follow-up of 6 months; therefore, the primary determining factor for selection of either technique is surgeon preference and appropriate case selection

RESUMO

Aim: The present study aimed to investigate if the Guatemalan dentist's options on tooth bleaching could be influenced by their time in clinical practice, the level of specialization or their working place. Methods: A representative sample of dentists working in clinical practice in Guatemala was selected. Data were collected using a self-administered questionnaire with information related to gender, professional characteristics (time since graduation in years and working place) and preferences regarding vital (at-home or in-office; type and concentration of bleaching agent) and the nonvital tooth bleaching (bleaching agent used). The analysis was performed and the association between preference for bleaching technique and independent variables were investigated using Fisher's exact test. Results: 200 dentists were interviewed. More than half of dentists were male (57.0%) with time since graduation between 11 and 20 years (n= 64; 32.3%). Dentists mostly (60.5%) preferred in-office technique for vital bleaching, with 10-20% Carbamide peroxide (CP) as the preferred agent (50%). For nonvital teeth, the preferred agent (46.8%) was 37% Hydrogen Peroxide (HP). About the associations, younger dentists (< 20 years of graduation) selected mostly in-office technique, while those with more than 20 years indicated more the at-home technique. Also, the dentists working in private practice chose more frequently in-office technique. Thus, the in-office technique was more popular among Guatemalan dentists, with 10-20% CP and 37% HP selected as favorite bleaching agents for vital and nonvital techniques, respectively. Conclusion: The time of clinical practice and working place influenced some choices

RESUMO

Aim: The aim of this study was to compare the microtensile bond strength (µTBS) and the characteristics of the adhesive interface of Scotchbond Universal - SU ­ etch-and-rise mode (3M ESPE) and Adper Scotchbond Multi-Purpose - MP (3M ESPE) to dentin over time. Methods: Class I cavity preparations were performed in 60 human molars that were randomly divided according to the dentin bonding system (DBS) used (n=30): (1) Acid conditioning + SU and (2) Acid conditioning + MP. For bonding strength (BS) analysis, 30 teeth (n = 15) were sectioned into sticks and submitted to the microtensile test in a universal testing machine after 24 hours and 12 months. The adhesive interface of the others 30 teeth was analyzed in a confocal microscope after 24 hours and 12 months. The data of µTBS were analyzed by two-way repeated measures ANOVA and Tukey's HSD (α = 0.05). Results: SU presented the lowest DBS compared to MP (p=0.000). Time did not influenced DBS for both adhesive systems (p=0.177). Confocal microscopy analysis showed no cracks between both adhesive systems tested. Conclusion: The results indicate that MP - µTBS showed a better performance compared to SU in total-etch mode

RESUMO

Aim: Recent reports indicate that deproteinization of acid-etched dentin surface can extend penetration depth of adhesive agents. The main goal of the present research was to investigate the deproteinization effect of Nd:YAG and diode 940 lasers on acid-etched dentin and microleakage grade in class V composite restorations. Methods: 36 extracted human premolar teeth were selected to make standard buccal and lingual class V cavities. These samples were randomly split into three sub-groups: 1.Control group, in which composite was applied for restoration after etch and bonding process without deproteinization; 2.Nd:YAG laser group, in which the teeth were deproteinized with Nd:YAG laser after etching and painting internal surfaces of cavities with Van Geison stain and then composite restorations applied just as control group; 3.Diode laser group, in which the process was similar to Nd:YAG laser group, but instead, diode 940 laser was irradiated. The teeth were bisected into two equal longitudinal buccal and lingual halves. Marginal microleakage of samples was scored by using a stereomicroscope. Kruskal- Wallis, Mann-Whitney U and Fisher's statistical tests were employed for analysis of the obtained data. Results: A significant reduction in marginal microleakage was observed for both groups treated with laser (Nd:YAG and diode 940)compared to control (p=0.001 & p=0.047). There was no significant difference in marginal microleakage between Nd:YAG laser and diode 940groups (P = 0.333). Conclusion: Nd:YAG and diode 940 laser deproteinization of acid-etched dentin decreased the marginal microleakage of in-vitro class V resin composite restorations
