Avaliação do perfil de risco de cárie dentária em gestantes de Araraquara, Brasil

The knowledge of risk of carried during pregnant is essential for an appropriate treatment using educational and preventives actions to mother for a good care of their oral health and that of children. The main objective of present retrospective study was to identify the risk of caries of pregnants (aged 15-44, mean= 25 years) came to clinic of Preventive Odontology of Araraquara-UNSEP from 1999 to 2007, using 166 medical records obtained by the third pregraduate year students, following the pre-established guidelines. The information collected includes: classification of caries risk diagnosis, pregnancy trimester, carbohydrates ingestion (between or during foods), dental plaques (O'Leary's plaque control registry) and the number of teeth with caries. The statistical analysis used the Chi2 and ANOVA tests. Most of patients showed a 25 % or more of teeth surfaces with dental plaques (92.1 %) and carbohydrates consumption among foods (89.2 %). The mean (SD) of carried and restores teeth was of 7.9 (5.1) and 4.0 (3.4), respectively and the posterior teeth were the more involved by caries/restorations. As regards the diagnosis of caries risk, classification of high risk was observed in the 38.5 % of pregnants, moderate in the 47.6 %) and low in the 13.9 %. There was a statistically significant association (p= 0.001) between the carbohydrates consumption and the diagnosis of caries risk. The plaque's rate was similar in the different trimesters of pregnancy (f= 0.223; p= 0.803). The caries risk of most pregnant women was high or moderate and it was associated with the consumption of carbohydrates.

Multidisciplinary approach in the teaching of dental sculpture and anatomy

The purpose of the Dental Sculpture and Anatomy discipline is to introduce undergraduate students to the study of the anatomic and morphological characteristics of permanent and primary human dentition, through classes, books and cognitive and psychomotor activities. This discipline supports the teaching of specific knowledge necessary for a more extensive education, involving interdisciplinarity as a means of knowledge exchange among several areas of dentistry, to achieve comprehensive professional education. Students must recognize the dental morphology from samples of preserved teeth, and reproduce the morphology through three-dimensional models made of stone or wax blocks. In this article, the authors describe the process for producing teeth collars and macro dental models made of stone, their importance and benefits of utilization. The purpose of the study was to encourage the teaching of Dental Sculpture and Anatomy toundergraduate students of the Bauru School of Dentistry, University of Sao Paulo, through activities that would associate theory, practice and the development of manual skills.

Acupuncture as therapeutic resource in patient with bruxism

Bruxism is the harmful habit of clenching or grinding the teeth during the day and / or night, with unconscious pattern, with particular intensity and frequency, outside the functional movements of chewing and swallowing. It is accepted that bruxism is a response controlled by the neurotransmitters dopamine system associated with emotional component. The proposed of treatment of bruxism with acupuncture aims to stimulate sensory fibers of the peripheral nervous system leading to electrical transmission by neurons sufficient to produce changes in the central nervous system. As a consequence there is the release of substances (cortisol, endorphins, dopamine, noradrenaline and serotonin) that promote wellness and restoration of harmony, be it psychological, biological and / or behavioral.

Clareamento dentário x autoestima x autoimagem

Dental changes that compromise facial harmony can have serious consequences on the social image of the patient. Depending on the emotional significance for the individual it can change interpersonal relationships, causing profound changes in their patterns of self-acceptance and self-image, with profound effects on their self-esteem of the patient. The search for tooth whitening as cosmetic factor for a harmonic smile grew sharply in the last decade. Although the color of the tooth represents only one aspect in the set of determinants of facial harmony, it is a strong factor because it is quickly perceived. This study aims to report the clinical case of a patient with spots on their upper central incisors. For the patient these spots have compromised her smile, causing harm and discomfort in their everyday social and professional relationships.

A experiência da saúde coletiva na formação profissional: retrato da extensão universitária

The guidelines of National Curriculum for Dental courses highlights the necessity in providing for the professional the ability to analyze and assess community’s problems and needs, and to create solutions for the society. The continuing education may be considered a useful tool for the teaching and learning because it favors the diversification of learning environments, which allows the insertion of undergraduate and graduate students into the real scenarios. This current study aimed to assess the Public Health projects and programs of the UNESP – Araçatuba Dental School, by describing the interaction experiences between faculty and health services in the professional career development. Historical, documentary and descriptive searches were performed based on the faculty archives such as official documents, reports, databases from the Pro-rector of continuing education and published papers in the period between 1964 and 2011. The following experiences were noted: the Extra-Muro Dental Service (SEMO), established in 1964, that focused in providing dental treatment to the rural population, highlighted the social inclusion of discriminated society groups since that time. In 1972, this service was expanded to several specific populations living in the urban areas. In the '60s, many educational campaigns were performed as homemade water filter and construction of wells and septic tanks which demonstrate the concern with the determinants of healthdisease process. At that time, the campaign of fluoridation of public water supplies in several counties started as Araçatuba, Birigui, Penápolis, Guararapes, Valparaíso and so on. The Campaign of “Good Teeth” from the '70s became wider over time and it was transformed in the "Oral Health Education Program" and it was continuously developed in all public schools of Araçatuba and some neighboring towns, benefiting children aged from 6 to 10 years-old. Several epidemiological studies of caries, periodontal diseases, malocclusion and fluorosis were conducted in cooperation with local governments, and counted with the participation of undergraduate and graduate students. Pereira Barreto – SP was the precursor city in Brazil to carry out fluorosis study. Currently, 12 projects of Public Health from the Institution of Higher Education in the Pro-rector of continuing education are being developed. The concern in qualifying the human resources in health is confirmed with the development of training courses and workshops for professionals, highlighting the training for people enrolled in the Family Health program; Community Health Agent training - Solidarity University, and Municipal Health Counselors training. The Graduate Program in Social and Preventive Dentistry, created in 1993, has an important role to train several professionals for the Unified Health System, and provides education to create researchers, professors and administrators, and enucleates research groups in several Brazilian states. In all activities showed herein, a dynamic participation of undergraduate and graduate students has been observed, and several books, guidelines, articles, brochures and booklets have been published as a result of the continuing education activities.. It was concluded that different projects and programs have been developed by the Public Health of UNESP –Araçatuba Dental School, which allow the exchange of experience between the university and health services, and benefit all participants enrolled in these activities.

Pistas diretas para o tratamento de mordida cruzada posterior

The malocclusions are one focus of discussions in public health, due to which it is necessary to incorporate correction procedures that are inexpensive, easy to perform and which can be made in health services. Planas Direct Tracks meet such characteristics which make them advantageous for the crossbite correction. The aim of this study was to present a case in which correction of unilateral crossbite was performed with the resources available in a public clinic. This is a 6 year-old patient who presented functional unilateral crossbite in canines and posterior teeth. A cross decreased maxillary arch leading to a condition of unilateral posterior crossbite was detected. Occlusal adjustments were performed in canine and posterior teeth; however it was not enough to restore the occlusal balance. It was decided to prepare Planas Direct Tracks in canines, allowing functional balance, which prevented masticatory movement alteration during the growth phase and malocclusion correction. Controls were performed every six months to evaluate the patient's progress and whether or not new occlusal adjustments were necessary. Monitoring and treatment were conducted for 5 years, until stabilization of the permanent dentition ensuring treatment. It is concluded that Planas Direct Tracks were effective for the correction of unilateral posterior crossbite. So, it is essential to note that this procedure can be performed in public services.

Case report: Cornelia de Lange Syndrome (CDLS)

The Cornélia of Lange´s syndrome is a genetic anomaly, described and published by Cornelia Catharina of Lange in 1933, however, their aspects were described previously by Winfried Robert Clemens Brechmann in 1916, that’s why it is also known as Brachmann of Lange’s syndrome. The most frequent clinical characteristics include typical face dismorfia, variable degree of mental delay, anomalies of the hands and feet, multiple malformations, retardation of the pre and postnatal physical development and microcephaly variable intellectual compromising. Some facial characteristics are peculiar and they are mixed with the inherited lines of their own family, the united brows, the long lashes, the small nose, the round face, the fine lips and lightly inverted. As oral manifestations they present micrognathia, dental crowding, periodontal disease, delayed dental eruption, enamel hypoplasia, erosion of the enamel and dentine caused by stomach acids of the gastroesophageal reflux and atresia of the dental arches. The purpose of this paper is to present a clinical report of a boy bearer of this syndrome assisted at CAOE - FOA - UNESP, emphasizing the importance of multiprofessional team for the diagnosis and treatment of this syndrome.

Mordida cruzada posterior, correccion y consideraciones: caso clínico con 7 años de seguimiento

Early treatment of functional unilateral posterior crossbite during the mixed dentition is extremely important for contemporary Orthodontics, provides the correct positioning of osseous bases, teeth and temporomadibular joint when the stomatognathic system is in growth and development. These results generally develop into an adequate craniofacial relationship, reducing the necessity for more complex treatments at permanent dentition. The subject of this paper was to report patient 8 years old, diagnosed with functional unilateral posterior crossbite, and was treated by an expander appliance type Quad-helix emphasizing the long-term stability. The malocclusion was corrected in 3 months of active use of the appliance, 3 months for retention purposes and followed up during 7 years post-treatment. The stability in long term of functional unilateral posterior crossbite treated is closely related with early diagnostic, the elimination of the etiological factor associated with a correct appliance and the mechanic of treatment.

Absentismo laboral por patología odontológica y médica en una industria de gran porte del sector mecánico y mueblero

Introduction: The current Brazilian legislation states that health services must be performed by the Specialized Service of Safety Engineering and Labor Medicine (SESMT). Objective: To analyze the dental and medical reasons for absenteeism, checking the interference of factors such as age, gender and position of the worker, and most of the reasons that led the employee to miss work. Material and methods: The research appears as a descriptive study with a quantitative approach. The dental and medical certificates and statements of attendance were analyzed, duly approved, lodged in a acrylic industry in the city of Araçatuba-SP, from January to July 2011. Results: Of the total number of certificates (n = 1841), only 103 (5.6%) were for dental reasons. Predominance of the age group of 20-29 years, males and with non-administrative function. The reasons most dental and medical certificates stated that led the workers to miss working days were "inclusive and impacted teeth" and "diarrhea and gastroenteritis of presumed infectious origin", respectively. As to factors related to absenteeism, there was a severity index of 2.83, 1.33 frequency and average duration of absences of 2.12. Conclusions: It is concluded that dental reasons had little weight on total absences due to illness that caused the temporary leave of the worker for a shorter period. The age and function variables influence the occurrence of work absenteeism.

Avaliação da resistência adesiva de diferentes sistemas resinosos de colagem ortodôntica

Recent orthodontic bonding materials have aimed to reduce the working time of the clinician, by simplifying the acid etching procedure by applying self-etching primer adhesive systems. However, the adhesion quality of these materials still demands investigation. Thus, the present study aimed to evaluate the bond strengths of three different adhesive systems. A hundred and eighty bovine lower incisors were cut and embebbed in acrylic resin matrices, in which orthodontic brackets were bonded with Transbond XT (2n = 60), Transbond XT Self Etching Primer (2n = 60) e Tyrian (2n = 60). For each composite, bond strength tests were executed immediately (n = 30) and 24 hours (n = 30) after the bonding, in the assay machine Versat 2000 (Pantec), by applying 500 Kgf of load at 1mm/min of velocity. Transbond XT, Transbond XT Self Etching Primer and Tyrian presented, respectively, average values of bond strength of 7.43, 7.09 and 3.41 MPa at the time immediately, and 7.42, 8.81 and 5.35 MPa at 24 hours after the bonding, where differences were statistically significant at 5% between Tyrian and Transbond groups at both observation times. It was concluded that Tyrian was the material that presented significant lower bond strength with regard to Transbond groups that were similar.

Factores que afectan la emisión de escapo floral y producción de bulbillos aéreos en ajo (Allium sativum L.)

El ajo constituye el principal producto agrícola no transformado destinado a la exportación en Mendoza. En la Argentina, la ausencia de cultivares específicas de ajo y producción de semilla fiscalizada han sido unas de las principales debilidades del sistema exportador. Para que los materiales provenientes de los planes de mejoramiento y saneados lleguen rápidamente al productor es necesario acelerar la tasa de multiplicación de los mismos. Con esta finalidad, los bulbillos aéreos que se forman en el extremo del escapo de ajo tipo “colorado" (Grupo IV, Argentina) libre de virus, pueden ser utilizados como propágulos en la producción de ajo “semilla". El objetivo general del presente trabajo fue establecer la influencia del: genotipo, liberación de virus (OYDV y LYSV), tamaño de “diente" empleado como propágulo, fertilización nitrogenada y conservación de los escapos luego de la cosecha, en la producción de bulbillos aéreos. En Mendoza, Argentina, se evaluaron durante el ciclo 1994, 32 introducciones de ajo tipo “colorado" de distinto origen, por su hábito de floración y producción de bulbillos aéreos. Se llevaron a cabo durante los años 1995 y 1996 dos ciclos de ensayos, en los que se evaluó en una población clonal de ajo “colorado criollo" (AR-I-051) y una de ajo “ruso" (AR-I-033) el efecto del saneamiento viral sobre la floración y producción de bulbillos aéreos, trabajando con material crónicamente enfermo y libre de OYDV y LYSV. En AR-I-051 además se estudió el efecto del tamaño de “diente" (2; 3,5 y 5 g ó 1,2; 3,2 y 5,2 g) e influencia de la fertilización nitrogenada (0, 50 y 100 kg.ha-1 de N como SO4(NH4)2). Entre 1995 y 1998, se compararon diversas métodos de “curado" de los escapos luego de la cosecha de las plantas (en planta entera, cortados de distintas longitudes, mantenidos en seco o con inmersión de sus bases en agua o en solución nutritiva con o sin el regulador del crecimiento CCC). Se concluye que la producción de bulbillos aéreos depende del genotipo considerado. En ajo “colorado" se distinguen 5 grupos por su modalidad de floración y potencialidad de producción de bulbillos. La producción de bulbillos aéreos útiles (>2,4 mm de diámetro) depende del tiempo transcurrido entre floración y cosecha y no entre plantación y floración. Se puede predecir la cantidad de bulbillos aéreos útiles (Numa) sobre la base del diámetro de espata (espa) y la longitud de escapo (long) al momento de cosecha, según la ecuación: Numa = - 81,62 + 4,79 espa + 1,05 long (r2 = 0,88). v La capacidad de cada genotipo de emitir escapos, disminuye con la liberación de OYDV y LYSV, por lo que la producción por hectárea de bulbillos aéreos útiles es menor en el material saneado. El empleo de material saneado, “dientes" grandes, como la fertilización con N producen plantas de mayor tamaño y con mayor área foliar, lo que se traduce en un mayor rendimiento en la producción de bulbos. Sin embargo, la producción de bulbillos aéreos por hectárea disminuye, debido al menor porcentaje de plantas que emiten escapos y no a la disminución del número de bulbillos por planta. En cambio, todas aquellas condiciones que favorecen menor expresión vegetativa de las plantas aumentan la emisión de escapos. El “curado" de los escapos separados de la planta madre se puede llevar a cabo sin necesidad de realizar la inmersión de la base de los mismos en agua o en solución nutritiva con o sin CCC. La longitud a la cual se deben cortar los escapos, de manera de no afectar la producción de bulbillos, depende del grado de crecimiento de los bulbillos en el campo. La longitud de corte del escapo en ajo “criollo", con escaso crecimiento de los bulbillos aéreos en el campo, no debe ser inferior a 50 cm. En ajo “ruso", que presenta al momento de cosecha de las plantas un desarrollo avanzado de los bulbillos aéreos, los escapos pueden cortarse de menor longitud, sin afectar la producción de bulbillos aéreos. La longitud del escapo, en planta o separado de ella, afecta la producción de bulbillos aéreos en forma directamente proporcional.

Estudio de procesos de deshidratación industrial de ajo con la finalidad de preservar alicina como principio bioactivo

El ajo es ampliamente conocido por sus propiedades benéficas para la salud y por sus características sensoriales. Además de su consumo en fresco, se elaboran diversos subproductos industriales, entre ellos se destaca el ajo deshidratado. Este producto se emplea tanto para consumo como condimento como para la elaboración de fitofármacos. Un atributo de calidad buscado en el polvo de ajo es que tenga elevados contenidos de principios bioactivos, especialmente, para la elaboración de preparaciones galénicas. Los fitoquímicos presentes en el ajo son compuestos organoazufrados y el más importante y representativo del grupo es la alicina. Diversos autores coinciden en que las tabletas comerciales de ajo en polvo evidencian grandes fluctuaciones en el contenido de alicina. Estas pueden deberse a las diferencias en la materia prima y a las pérdidas durante el proceso de deshidratación industrial. El objetivo del trabajo fue evaluar los niveles de alicina en polvos de ajo obtenidos mediante distintos procesos de deshidratación. Se trabajó con ajo cv Sureño INTA. Los bulbos fueron seleccionados y los dientes pelados en forma manual. La pasta de ajo fue obtenida mediante molino helicoidal y homogeneizador. Los tratamientos fueron: deshidratación en Spray, en horno Terminador y en horno de deshidratación de Usos Múltiples. También se evaluó la eficacia del empleo de aditivos microencapsulantes (goma arábiga) en los distintos tratamientos de deshidratados: tipo Spray, Lecho Espumado. La evaluación de los procesos fue realizada mediante la medición de humedad y alicina (HPLC). Además, se cuantificó alicina en productos de ajo deshidratado disponibles en el mercado. De todos los tratamientos, el proceso de deshidratación Spray evidenció las menores pérdidas de alicina, en las condiciones bajo estudio. De lo que se desprende, que las condiciones para la deshidratación de alta temperatura, corto tiempo y empleo de aditivo microencapsulante resultaron propicios para preservar alicina.
