Abstract Introduction composite resins are materials widely used for Class II restorations, to restore the anatomization of the dental element. However, there are several factors that can interfere with the quality of a good restoration. Objective the objective of the present study is to carry out a retrospective evaluation of the clinical performance of Class II restorations performed by undergraduate students of Dentistry at the Escola São Francisco de Assis (ESFA), and to identify the main errors. Material and method we selected the medical records of patients treated in the disciplines of Dentistry II, Integrated I and II in the Dentistry clinic at ESFA, which presented detailed information on the Class II procedure, as well as initial radiographic examinations, using the FDI method. The sample consisted of 33 medical records that included 72 teeth. Result it was observed that more than 80% of the restorations were classified as acceptable. And, only 19.44% of the restorations were unacceptable, failing due to functional and biological properties. Conclusion it was found that undergraduate students in Dentistry at ESFA, who are guided by professors to perform treatments following pre-established clinical protocols, are capable of carrying out quality restorative procedures.

Abstract Introduction older persons in Long-Term Care (LTC) facilities have functional impairments and a higher disease prevalence. Nurses’ comprehensive assessment of older persons’ health is highlighted, including using tools for screening dental treatment needs. Objective to report the intra- and inter-observer reliability of older adults’ oral health assessment in LTC facilities by video. Material and method descriptive study, in three LTC facilities, in the Florianópolis region, Southern Brazil. Data were collected according to Oral Health Assessment Tool (OHAT), which presents 8 categories (“lips, tongue, gums/tissues, saliva, natural teeth, dentures, dental hygiene, and toothache”), and the scores 0=healthy, 1=presence of changes (could be a need for care), 2=unhealthy (need for dental service); final score from 0 to 16. In each LTC facility, a Nurse assessed oral conditions and made a video of each older adult using a smartphone. The dentist performed the oral health assessment through the videos. Estimated Kappa test, p<0.05. Result the sample was 34 older adults, 71% were female. Interobserver reliability between Nurses 1 and 2 and Dentist for “lips” and “natural teeth” was classified as poor and excellent/very good for toothache and denture conditions. The nurse’s intraobserver reliability was classified as weak for the “natural teeth” assessment. Conclusion the OHAT showed reliability for assessing denture conditions and pain. However, nurses’ training for recognizing oral conditions that require dental care is suggested, as well as the management of this action by the dentist and LTC facilities.

Resumo Introdução A estabilidade primária é um importante indicador de sucesso da osseointegração. Porém, fatores locais com osso de baixa intensidade podem interferir negativamente na obtenção da estabilidade primária. Objetivo O presente estudo avaliou o efeito de diferentes direções, velocidades de rotação e sistemas de fresagem na expansão de perfurações e estabilidade de implantes instalados em blocos mimetizando osso do tipo IV. Material e método Foram instalados 50 implantes em blocos de poliuretano sólido rígido. Esses implantes foram igualmente divididos em cinco grupos (n = 10): 1) Fresa Maximus (utilizadas no sentido horário a 1200rpm); 2) Fresa Maximus (utilizadas no sentido horário a 600rpm); 3) Fresa Neodent (utilizadas no sentido horário a 800rpm); 4) Fresa Neodent (utilizadas no sentido anti-horário a 800rpm); 5) Fresa Neodent (utilizadas no sentido anti-horário a 600rpm). Foram executadas análises de estabilidade dos implantes através de testes de torque de inserção e remoção, além das análises de frequência de ressonância. Adicionalmente, a expansão associada às perfurações promovida pelas brocas foi avaliada por meio de análises tomográficas. Resultado Verificou-se que os implantes instalados após o preparo da perfuração com as brocas Maximus a 600rpm apresentaram valores de torque de inserção maiores, quando comparados ao grupo de implantes instalados em perfurações confeccionadas com brocas Neodent. Ademais, as brocas Maximus apresentaram valores de expansão maiores que as brocas Neodent. Conclusão As brocas Maximus são mais eficientes em promover a osseodensificação, e sua utilização está associada ao aumento da estabilidade dos implantes instalados em blocos mimetizando osso do tipo IV.

Abstract Introduction Osteoporosis is a metabolic disease characterized by reduced bone mineral density, often accompanied by loss of quality of trabecular bone microarchitecture. Objective To assess the quality or degradation of trabecular bone microarchitecture in digital panoramic radiography to better predict the risk of fragility fractures. Material and method The sample included 68 female patients, age-matched, and divided into three groups according to densitometric results. Trabecular Bone Score values were measured and digital panoramic radiographs were taken. Fractal analysis with box counting was conducted in the region of premolars and angle of the mandible, with regions of interest measuring 64×64 and 80×120 pixels. In the statistical analysis, Pearson’s correlation was applied between the Trabecular Bone Score and fractal analysis results obtained in each group, using age as a control variable and assigning individualized age ranges within groups. Result A moderate correlation was identified in the regions of interest of 64×64 and 80×120 pixels at the angle of the mandible in the osteoporosis group and in the normal group. A moderate correlation was also obtained using age as a control variable in the 64x64 pixel regions of interest in the premolar region. Considering age range, the within-group analysis presented a strong correlation in the osteoporosis group and moderate correlation in the osteopenia and normal groups. Conclusion Fractal analysis in digital panoramic radiographs was shown to be a promising predictive instrument of bone microarchitecture quality.

Abstract Introduction Some experimental models have been used to evaluate the use of biomaterials in bone regeneration. Among them are the critical size defects (CSD) created in rat calvaria. An experimental model has been described in the literature, in which “L” markings are performed on the margins of the bone defects in order to assist in the precise identification of these defects during laboratory processing and analysis of the results. In the proposed model, the “L” markings are filled with amalgam. Objective The purpose of the present study was to evaluate the amalgam replacement of an experimental bony defect model in rat calvaria by heated or unheated glass ionomer. Material and method 24 rats were used. A 5 mm CSD was created at each animal calvaria. Two “L” shaped markings were made 2 mm from the margins of the bone defect, filled with amalgam (Group AM), heated glass ionomer cement (Group GIh) or not (Group GI). The animals were euthanized 15 days postoperatively. The areas of the surgical defect and the L-shaped marking were histomorphometrically analyzed and the data were analyzed statistically (p <0.05). Result There were no significant clinical, histological or methodological differences among the experimental groups. Conclusion It can be concluded that GI can replace AM in the proposed experimental model and GI heating did not promote additional benefits.

Abstract Introduction Primary stability is one of the goals of modern implant dentistry and if achieved, reduces treatment time for prosthetic rehabilitation and the number of interventions made in patients mouth. Several companies state as protocol for connical conection implants, a subcrestally positioning. Objective This in vitro study aimed to evaluate the effect of placing a conical connection implant equicrestally and subcrestally on static and loading condition in two types of bone density. Material and method A total of 200 bone cylinders were extracted from femur of pigs, standardized by means of x-rays and computerized microtomography scan (microCT) and separated in low and high density specimens. The implants were placed on the center of the bone cylinders and were evaluated before and after loading by means of microCT and histomorphometry. Result The results showed that placing the evaluated implant subcrestally provided better primary stability and performance on static and loading situations on low and high density bone. Conclusion Placing implant subcrestally improve primary stability outcomes under loading and static situations.

Abstract Introduction Orthodontic movement can cause painful symptoms, especially in the early stages of treatment. Objective This study aimed to compare the performance of chewing gum and ibuprofen in pain control during the initial period of orthodontic treatment. Material and method A randomized blind clinical trial, with an allocation ratio of 1:1, was developed with patients aged ≥18 years old. The sample size was established considering a significance level of 5% and test power of 80%, resulting in a minimum of 30 volunteers per group (n=90). Participants were paired regarding sex, age, the severity of malocclusion, defined by the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN), and crowding, determined by Little’s irregularity index. The sample was randomly allocated to three groups: Group I (control) placebo; Group II chewing gum; and Group III Ibuprofen. Pain perception was evaluated by the Visual Analog Scale (VAS) in the first 24, 36, and 48 hours after activation of the orthodontic appliance. The data were analyzed by generalized linear models for repeated measures in time. Result No statistically significant difference (p>0.05) was observed among the groups for the methods of pain therapy evaluated in 24, 36, and 48 hours post-activation. Conclusion There was no difference among the method used for pain control during the orthodontic treatment.

Abstract Introduction Screw-retained restorations have a screw access hole (SAH) sealed with resin composite aiming at safe-guarding the aesthetic features of the ceramic veneer. The loss or wear of the resin composite applied in sealing the SAH is among the most common complications in implant prosthodontics, as the fracture of ceramic veneer. Objective Evaluate the influence of sealant materials on the fracture resistance of resin composite applied in sealing screw access hole in screwed (SAH) implants. Material and method The samples were produced from UCLA abutments in metallic NiCr alloy with subsequent application of ceramic. After asperisation and conditioning ceramic surface, was applied silane and dentin adhesive, before sealing the conduits with resin composites Z100 and P60. Nine groups (n=10) were evaluated: sealing with Z-100 (ZNC) and P-60 (PNC) without obturation of SAH; sealing with Z100 (ZCP) and P-60 (PCP) with absorbent cotton; Z100 (ZPT) and P60 (PPT) with polytetrafluoroethylene; Z100 (ZGP) and P60 (PGP) with gutta-percha and a cemented ceramic crown (ICS). After the fracture resistance test, the data were analyzed using two-way ANOVA and Tukey HSD tests (p<.05). Result The fracture mode was evaluated by scanning electron microscope. Irrespective of the filling material, the highest mean values of fracture resistance were observed in the sealing with P60 (p=.002). When combined with resins composed of a sealing material, the results obtained were: ZGP: 805.5N/ PGP: 929.5N

Resumo Introdução a busca por atendimento odontológico é um parâmetro importante para averiguar como os indivíduos compreendem a saúde bucal. Objetivo avaliar a utilização de serviços odontológicos e fatores associados em pacientes oncológicos em Minas Gerais, Brasil. Material e método estudo transversal, realizado com uma amostra de 441 pacientes adultos frequentadores de uma associação voluntária de apoio a pacientes oncológicos no Estado de Minas Gerais, Brasil. O desfecho foi avaliado por meio do autorrelato de consulta odontológica no último ano. As variáveis independentes incluíram condições socioeconômicas, saúde geral e relacionada ao câncer, saúde bucal e cuidados odontológicos. As associações entre o desfecho e as variáveis independentes foram testadas por meio de regressão logística bivariada e múltipla, sendo os resultados expressos por meio de odds ratio (OR) e intervalos de confiança de 95% (IC95%). Resultado a prevalência de consulta odontológica no último ano foi de 33,3%. Os indivíduos que possuem entre quatro e sete (OR: 1,80; IC95%: 1,02-3,18) e aqueles com oito ou mais anos de estudo (OR: 3,20; IC95%: 1,07-9,60) apresentaram maiores, enquanto os edêntulos (OR: 0,44; IC95%: 0,21-0,92) apresentaram menores chances de consulta odontológica no último ano, independentemente de condições socioeconômicas, saúde geral e saúde bucal. Conclusão foi baixa a procura por consulta odontológica no último ano entre os pacientes oncológicos. Além disso, houve desigualdades relacionadas à escolaridade e ao número de dentes remanescentes na utilização dos serviços. A identificação e priorização dos grupos com acesso desfavorável aos serviços são fundamentais no planejamento da prestação de cuidados odontológicos a essa população.

Resumo Introdução As disfunções temporomandibulares apresentam uma variedade de sinais e sintomas que afetam a articulação temporomandibular, músculos da mastigação e estruturas relacionadas e muitos pacientes apresentam queixas cervicais. Objetivo Verificar a correlação de dor à palpação dos músculos da mastigação (masseter, temporal anterior, pterigoideos lateral e medial) e digástrico, com a queixa de dor no pescoço; verificar a correlação de dor à palpação nos músculos da mastigação e digástrico, com dor à palpação no esternocleidomastoideo e trapézio, e se a força de correlação é diferente entre eles. Material e método Foram avaliados 232 prontuários da clínica odontológica das Disfunções Temporomandibulares da Faculdade de Odontologia de Araçatuba, do período de 2011 a 2013. Os dados coletados foram submetidos à análise estatística, com alfa (α) = 0.01 para todos os casos, exceto digástrico quando associado ao trapézio (α) = 0.05. Resultado A maioria dos pacientes era do sexo feminino. Houve correlação positiva entre dor à palpação nos músculos temporal, masseter, pterigoideo lateral, esternocleidomastoideo e trapézio, e queixa de dor no pescoço. Também houve correlação positiva entre a dor em todos os músculos da mastigação (masseter, temporal, pterigoideo lateral e medial) e digástrico e a dor no esternocleidomastoideo. Bem como a correlação de presença de dor nos músculos masseter, temporal, pterigoideo lateral e digástrico com dor no trapézio. A correlação de dor foi mais forte para o músculo esternocleidomastoideo, exceto para o pterigoideo lateral. Conclusão Existe correlação positiva entre a queixa de dor à palpação nos músculos da mastigação, exceto pterigiodeo medial, e os músculos cervicais (esternocleidomastoideo e trapézio). A força de correlação entre a dor do masseter e temporal anterior com o esternocleidomastoideo é mais forte do que com o trapézio.
