Autopercepção e condições de saúde bucal em gestantes

This study ev aluated oral health indic ators by determining the pr evalence of dental c aries, periodontal diseases, prosthetic conditions and need in pr egnant women; identifi ed self-perceived oral health status and evaluated association bet ween variables. A clinical examination was performed in fi fty pregnant women assisted in the Preventive Dentistry Clinic-FOAr-UNESP using traditional oral health indicators: DMFT, C ommunity Periodontal Index ( CPI) and pr osthetic c onditions. A semi-struc tured questionnair e was applied to identify oral health perception and to collect sociodemographic variables. For data analysis, pregnant women were allocated in three groups according to their oral health perception (good, fair, poor) and compared according to clinical variables by the Kruskal-Wallis and Dunn tests. DMFT was high, all of them showed periodontal changes, most do not use and do not r equire any type of prosthesis; 36% considered their oral appearance as good. There was signifi cant diff erence between groups for the DMFT index and prosthetic need. It may be concluded that despite dental caries experience of pregnant women was found to be high, the prosthetic need have been detected in most of them and the presence of calculus was observed in all the volunteers, the majority considered their oral health status satisfactory.

Aplicação do laser Er,Cr:YSGG em periodontia e implantodontia: revisão de literatura

Lasers are widely used tools in many therapeutic modalities in medical lasers and can be divided into low and high intensity. For the treatment of periodontal disease, lowintensity lasers are related to reduce the number of bacteria and to induce inflammatory and analgesic properties. The high intensity lasers can be used in surgical procedures, improving hemostasis, promoting more accurate cuts, removal of dental calculus as well as thermomechanical and photochemical interactions with tissue. The high-intensity laser Erbium impregnated with chromium: YSGG laser has shown satisfactory results when applied in endodontic, restorative denstistry, surgical procedures and non-surgical periodontal treatment. The purpose of this review is to evaluate the studies that investigated the effects of Er, Cr: YSGG laser on the morphology and biocompatibility of titanium and root surfaces irradiated with these lasers, even beyond the effect on the treatment of periodontitis and periimplantitis.

A utilização do enxerto ósseo autógeno para tratamento de lesão de furca grau II

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.

Instrumentation of dental implants: a literature review

The aim of this study was to review the literature on the systems used to decontaminate the implant's surface. Different instruments have been proposed, but there is no agreement in the literature about which methods would be more efficient with no damage to the implant surface. It was reported the use of plastic, carbon fiber, stainless-steel and titanium curettes and also the use of other systems such as ultrasonic points with different tips, rubber cups and air abrasion. Literature review: In most of the studies, the injury caused on the titanium surface at the time of instrumentation was examined. In others, the cell adhesion on the titanium dental implants following instrumentation of the implant surface was observed. Moreover, to enhance cleaning around implants, ultrasonic systems were recently tested. Conclusion: Metal instruments can lead to major damage to implant surface, therefore, they are not indicated for decontamination of dental implants surfaces. Furthermore, non-metallic instruments, such as plastic curettes, rubber cups, air abrasion and some ultrasonic systems seem to be better choices to remove calculus and plaque of the sub- and supra-gingival peri-implant area. It is noteworthy that more studies evaluating the effects of these systems are required to establish best practices to be used in the treatment of patients with dental implants.

Impacto dos problemas de saúde bucal na qualidade de vida de gestantes

Objectives: 1) to evaluate the impact of oral health problems on the quality of life of pregnant women by the simplified Oral Health Impact Profile (OHIP-14) questionnaire as well by the presence of dental caries, periodontal disease and denture use/need; 2) to correlate the sociodemographic variables and the oral health conditions revealed in the clinical examinations with the OHIP-14. Method: In addition to the application of the OHIP-14 questionnaire, clinical examination of the oral conditions (CPI - community periodontal index, DMFT and prosthetic evaluation) was performed on 51 pregnant women, who sought dental treatment between April 2008 and August 2010 at the Preventive Dentistry Clinic. Descriptive analyses were made for sample characterization, bivariate analysis (chi-square or Fisher’s exact tests) and multiple logistic regressions at a 5% significance level to assess the correlation between the impact of oral health on the quality of life of pregnant women and the socio-demographic and clinical variables. Results: The OHIP-14 data showed a lesser impact of oral health on the women’s quality of life. The mean DMFT was 12.8; 70.6% of the pregnant women presented dental calculus and 58.8% needed prostheses. The association between OHIP-14 data and last dental visit and DMFT remained in the final regression model (p<0.05). Conclusion: Caries experience of the pregnant women was considered high. Most of them needed prostheses and presented dental calculus. The OHIP-14 presented a low impact on this population and was significantly influenced by the last dental visit and the DMFT index.

A educação em Direitos Humanos nos projetos político-pedagógicos das escolas de São Paulo

The article presents data from a qualitative study that aimed to investigate the presence of aspects that integrate knowledge, values and practice of the Human Rights Education (HRE) in the political-pedagogical projects (PPPs) of public schools in the state of São Paulo. 15 documents were analyzed from criteria based on reference documents for HRE in Brazil. The criteria were organized into seven areas: internal and external community; principles and concepts of education; goals; curriculum; democratic participation and school environment; teacher training and evaluation. We sought to identify whether the HRE related elements were missing, or if they were just mentioned or stood out through propositional planned actions in PPPs. The data demonstrate that the contents directly related to HRE are absent from PPPs, some issues related to this type of education are weakly mentioned and there are some planned actions that promote rights. However, the intentional, systematic and conscious planning of HRE is not yet reflected in this document type.

About the minimum time transference in a fractional differential equation

The use of fractional calculus when modeling phenomena allows new queries concerning the deepest parts of the physical laws involved in. Here we will be dealing with an apparent paradox in which the time of transference from zero in a system with fractional derivatives can be strictly shortened relatively to the minimal time transference done in an equivalent system in the frame of the entire derivatives.

Simplified periodontal record for pregnant women

The assessment using the PSR (Periodontal Screening and Recording) of the prevalence and severity of and the basic treatment needs for periodontal disease in a group of pregnant women who attended the Preventive Dentistry Clinic at the School of Dentistry of Araraquara--UNESP. Forty-one pregnant women of 16 to 37 years of age, were examined. The PSR index was evaluated with a suitable periodontal probe (Trinity-model 621-WHO) with index codes scores of from 0 to 4, capable of indicating the presence of the following conditions: periodontal health, bleeding on probing, calculus, shallow and deep pockets. These codes were attributed to each sextant and could be marked with an asterisk (*) to indicate the presence of gingival recession, furcation lesions, mobility or any other mucogingival alterations. It is shown that 100% of the pregnant women had some kind of gingival alteration, represented mainly by PSR code 2 (56.1%) and * (19.5%). The women in the youngest age groups, 15-19 and 20-24 years, had code 2 as their highest score with no sextant excluded. In the 25-29 age group, the PSR code 2 still prevailed (54.5%) although codes 3 and 4 were already appearing. The code * and the occurrence of excluded sextants tended to increase in the oldest age group (30-37). In general, the affected sextants showed codes 1 and 2 more frequently, corresponding to 41.6% and 39.8% respectively, which represented a mean of 2.49 and 2.39 sextants affected in each pregnant woman. Regarding the treatment needs, 90.2% of the women needed some treatment beyond the preventive measures begun, including scaling and root planning and/or corrections of defective restorative margins (61%), and more complex treatment (29.2%). The meeting of the treatment needs during pregnancy must include special efforts to increase motivation and promote oral health, minimizing the possibility of vertical transmission of pathogenic microrganisms to the child, and thus contributing to the primary prevention of the main oral diseases.
