Retardo na procura do tratamento odontológico e percepção da saúde bucal em mulheres grávidas

The objective was to assess in women with children under 5 years old what happened to your pregnancy in relation to dental care, coupled with a probable correlation between the level of their knowledge on dental health and possible reasons which lead or have led to a late seeking such treatment. The interviews were conducted in an environment of health center in the city center and the Odontoly Faculty in Araraquara. Among the interviews mothers, 57% refused the dental treatment during pregnancy. It appears on mothers that are afraid to perform a dental treatment during pregnancy. The misinformation on this issue often associated with this belief in the medical field that dental care during the first three months of pregnancy is harmful to the baby. Such information passed on to mothers leads to a hesitancy with dental treatment during this period. The educational level of mothers did not interfere in this pursuit, and 24.5% of them avoid treatment during pregnancy. The difference, however, is between those mothers of high educational level, performing oral prevention before pregnancy.

Conhecimento odontológico de adultos atendidos em uma unidade de saúde da família do município de São Carlos, Brasil

The Family Health Strategy is a primary care public policy that is becoming a decisive step towards the transformation of the Brazilian healthcare model. This study evaluated the dental knowledge among individuals who attended a Family-Health Unit (FHU) in the city of São Carlos, SP, Brazil. Methods: The evaluation was based on a questionnaire with 20 questions about oral health, prevention and development of dental caries and periodontal disease. The questionnaire was given to 168 individuals, over 18 years of age and both sexes, to fill out under the supervision of a trained dentist. After data collection, the answers contained in the original questionnaires were entered into a database built using the program Excel® (Microsoft Corporation, USA) and a descriptive statistical analysis was done. Results: 66.67% of the subjects reported having received information about dental caries and periodontal disease before attending the FHU, and dentists were cited as the main source of such information (60.71%). With regard to dental caries, 70.24% of the individuals stated that they knew about the subject, but the majority of answers revealed incorrect explanation of it. The multifactorial etiology (bacteria/sugar/poor hygiene) was not mentioned. A low percentage of subjects (24.40%) claimed to know what periodontal disease is, and of these, the highest percentage of responses was related to gingivitis (26.83%) and gingival bleeding (12.20%). Out of all subjects, 80.36% affirmed that oral hygiene is important, and among them, the main reasons cited were the maintenance of oral health (29.63%), to avoid diseases (16.30%) and to preserve and prevent disease (14.81%). Conclusion: Responses from the questionnaires revealed deficient dental knowledge among the individuals. To improve the understanding about this issue, the information obtained through the questionnaire can be used to develop educational programs that will focus specifically on the major deficiencies found.

Elaboração de um curso interativo voltado ao aprendizado de um sistema aplicativo em Odontologia, utilizando a plataforma Moodle

In universities, in any type of faculty or research institute, it is possible to observe innumerable informatics applications: database management, organization of catalogues, expediting diagnoses and many other applications. Within this context, distance learning could facilitate the learning of various professions. Distance education is the process of teaching-learning and the professional has to be prepared to deal with the new tools that are made available, using them to his/her benefit, and consequently in his/her professional capacity, to guarantee greater productivity and interaction with the various spheres in the work field. Methods: The aim of this research is to develop a course on the use of the Dentistry software application EasyDental, using the teaching at a distance methodology by means of the Moodle platform. The proposed course was composed of 14 modules, in order to enable a progressive and a rational learning. Conclusion: It could be concluded that this platform allowed the preparation of the proposed distance course, in a practical and versatile manner, considering the resources and activities it has. However, to use this platform, one must have dominion of the basic concepts of informatics, and the tools of the Moodle platform.

Métodos de avaliação de risco de desordens músculo-esqueléticas nos membros superiores voltados para a odontologia

The dental professionals are exposed to many risks of development of occupational diseases and the musculoskeletal disorders in the upper limbs are the most common disease. This problem may result in lower productivity and / or early retirement. Therefore, early diagnosis should be done through a reliable and valid system of risk assessment. Because of that, this study set out to conduct a review of the literature on methods of risk assessment of musculoskeletal disorders in the upper limbs in dental professionals. Conclusion: It was concluded that the available methods for assessing the risk of musculoskeletal disorders in dentistry are self-reports, observational and direct. Among these methods, the self-reports were frequently used to detect the risk of musculoskeletal disorders among dentists, dental students and professionals from the dental team. Further studies should be performed in dentistry using observational and direct methods.

Reabilitação estético-funcional sobre implantes agulhados e endósseos

This report shows the resolution of a case study whose aim was promote the aesthetic and functional rehabilitation of upper left hemi-arch over endosseous and needle implant prostheses. To improve the position of the needle implants, we performed the bucco-palatal bending of needles splinting them with composite resin; we removed the screwed implant prosthesis in the regions of the premolars (24 and 25) and molar (26). The mini-abutments of the last two implants were replaced, and in the first premolar and canine, we used cemented abutments due to implant angulation having planned soldering because of implant size and contact with one needle implant that could interfere with intimate contact bone/implant damaging biomechanics. Pick-up impressions were performed with an open tray, using a retractor cord in the needle implants and respective transfer copings. Therefore, models were related on semi-adjustable articulator after a face-bow recording and interocclusal indexes. After working cast fabrication and try-in of infra-structures, these were adjusted and related into the articulator again. Then, after ceramic build-up, adjustments, finishing, and torque, chemically-activated resin cement was applied on units 21 to 24. At the end of the case, we concluded that a good aesthetic and functional rehabilitation depends on thorough knowledge of techniques for each clinical situation.

Prevalência de alterações locais e sistêmicas em indivíduos com disfunção temporomandibular

Temporomandibular disorder describes a variety of conditions including joint and muscle in the stomatognathic system, characterized by pain, TMJ sounds, functions irregular jaw and represent the leading cause of nondental pain in the orofacial region. The objective of this research was to evaluate the prevalence of ophthalmological, otological and cognitive-behavioral changes, parafunctional habits in individuals with temporomandibular disorders (TMD). A total of 117 medical records of female and male individuals, aged 18 to 60 years, from the Occlusion, Temporomandibular Dysfunction and Orofacial Pain of the Ribeirão Preto School of Dentistry – USP, between 2010 and 2011. The anamnesis index proposed by Helkimo was used to classify the individuals according to TMD severity degree and to divide them into two groups: AiI (mild to moderate) with 69 individuals and AiII (severe) with 48 individuals. The groups were then subdivided with respect to gender (72.64% female and 27.36% male) and age. There was predominance in the 18-40 year age group (60.68%) when compared to the 41-60 year age group (39.32%). Data were collected through an interview with questions about the presence of parafunctional habits, otological, ophthalmological and behavioral changes. Data were subjected to the statistical analysis using the Kruskal-Wallis test. The prevalence of each change was also evaluated. The results showed statistically significant for all groups according to gender, age and degree of severity. Individuals with temporomandibular disorders exhibited high prevalence of systemic and local dysfunctions.

Extensão universitária e trabalho voluntário na formação do acadêmico em odontologia

The aim of the present study was to point out the importance of the experience of undergraduate dental students in extra-curricular activities and volunteer work, as a means through which to gain essential knowledge and abilities for their professional lives. A literature review of the Medline, Scielo, and Lilacs databases was carried out in an attempt to select articles related to the university extension and volunteer work of undergraduate dental students. It is still extremely difficult to include university extension and volunteer work as an important activity in Dentistry courses. However, the presentday work market demands professionals who have expertise not only in dental techniques, but also in the socio-cultural characteristics of communities, considering that people need to be comprehensive in their psychosocial aspects in order to be treated as a complete professional. Therefore, university dentistry courses should give equal consideration to both oral rehabilitation skills and the promotion of general healthcare, acquired mainly through extracurricular activities, in an attempt to redeem the integral education of the healthcare professional. Moreover, students should pay closer attention to the opportunities offered during their undergraduate courses, as the work market for dentists is becoming more and more competitive. Moreover, the dentist whose professional life is limited to the dental office will most certainly forgo the opportunity to act in other social areas as well as the recognition that comes with such acts.

Matriz Bertholdo/Ricci/Barrotte (BRB): uma simplificação de técnica para obtenção de guia de estratificação com compósitos

Advanced Layering composite resins can be facilitated by a technique called "Lingual Matrix", where a guide is made of elastomer by molding a previously waxed tooth or sculped in an intraoral test drive restoration. This technique has many advantages to sophisticated layering, facilitation stratification, anatomic construcrion and the stages of finishing and polishing. However, in some clinical situations, the unfolding of the steps to obtains this matrix can be time consuming or even infeasible. To facilitate the achievement of this apparatus, a technique was idealized allowing significant reducrion in clinical time. This matrix, called the "BRB Matrix" is widly discussed in a didactic and clinical manner in this article, presenting its advantages in clinical cases where it is imperative to use a guide for conduction a controlled layering. The simplicity of this approach, as well as reduced clinical time and finacial costs turn it feasible in an everyday clinical practice.

Radiopacity and flow of different endodontic sealers

The present study evaluated the radiopacity and flow of different endodontic sealers: AH Plus, Endo CPM, MTA Fillapex, Sealapex, Epiphany, and Epiphany SE. For the radiopacity test, six specimens measuring 10mm in diameter and 1mm in thickness were fabricated from each material. They were radiographed on an occlusal film alongside an aluminum step wedge. Radiographs were digitized to determine the radiopacity equivalence in millimeters of aluminum. To evaluate the flow, a 120 g load was placed on top of a glass slab containing 0.05 } 0.005ml of sealer. The diameters of each material were measured (mm) with a caliper and samples were photographed. Digitized images were analyzed using the UTHSCSA Image Tool for Windows software, to determine the sealer area (mm2). Data were submitted to ANOVA and Tukey's test at 5% significance. AH Plus and Epiphany SE presented the greatest radiopacity (12.5 mm Al and 12.0 mm Al, respectively) (p>0.05), followed by Epiphany (9.6 mm Al) and Fillapex (8.9 mm Al). Endo CPM (5.46 mm Al) and Sealapex (5.51 mm Al) presented lower radiopacity. MTA Fillapex presented significantly higher values of flow than other sealers (33.11 mm and 844.9 mm2). AH Plus, Epiphany, and Epiphany SE had similar values. Endo CPM (21.05 mm and 342.8 mm2) and Sealapex (19.98 mm and 352.5 mm2) presented the lowest flow values (p>0.05). All sealers presented radiopacity and flow values according to ISO and ANSI/ADA recommendations.

Use of nanoparticulate zinc oxide as intracanal medication in endodontics: pH and antimicrobial activity

The aim of this study was to evaluate the pH and antimicrobial activity of micro or nanoparticulate zinc oxide (ZnO) pastes with or without calcium hydroxide (CH). The following medications were evaluated: microparticulate ZnO + polyethylene glycol (PEG) 400; nanoparticulate ZnO + PEG 400; PEG 400; CH + microparticulate ZnO + PEG 400 and CH + nanoparticulate ZnO + PEG 400. The pH was assessed between 12 hours and 28 days, using a digital pH meter. The antimicrobial activity against Enterococcus faecalis (ATCC-9212), Candida albicans (ATCC-10231), Pseudomonas aeruginosa (ATCC-27853), Staphylococcus aureus (ATCC-6538) and Kocuria rhizophila (ATCC-9341) was determined in triplicate using agar diffusion test. The results were submitted to Kruskal-Wallis/Dunn and ANOVA/Tukey tests with 5% significance. The highest pH values were found for CH+ZnO, with higher values for nanoparticulate ZnO after 12 hours and 21 days (p<0.05). CH+ZnO medication promoted higher growth inhibition against P. aeruginosa and lower against E. faecalis. Calcium hydroxide pastes have higher pH and antimicrobial activity when associated with either micro- or nanoparticulate zinc oxide.

Cirugía endodóntica con obturación simultánea del conducto radicular: caso atípico

The apical surgery with simultaneous root filling consists in the elimination of the local etiologic factors concomitant with the shaping and obturation of the root canal system. This technique is indicated when there is no possibility of obturating the root canal by conventional methods. Some adverse factors may difficult the clinical procedures, such as the radiographic interpretation. Periapical radiographs must not be used as the main diagnostic resource due to their inherent disadvantages, such as distortion and superimposition with other anatomical structures. The aim of this clinical case report is to show the limitations of radiographic examination in an apical surgery in which a root perforation was not visible in the radiographic image, as well as the gutta-percha was not related to its real clinical location.
