Estudo da ocorrência de recidivas após enucleação, seguida de ostectomia periférica e solução de carnoy no tratamento das lesões odontogênicas benignas agressivas / Study of the occurrence of recurrences after enucleation, followed by peripheral ostectomy and Carnoy's solution in the treatment of aggressive benign odontogenic lesions

Estudo seccional retrospectivo com o objetivo de investigar a ocorrência de recidivas em lesões odontogênicas benignas agressivas após o protocolo cirúrgico de enucleação, seguida de ostectomia periférica e solução de Carnoy. A amostra utilizada foi de conveniência e constituída por trinta pacientes atendidos no setor de Cirurgia de Traumatologia BucoMaxilo-Facial da UFRN no período de 2008 a 2018. Os dados foram coletados por meio dos prontuários clínicos e em seguida os pacientes foram contatados para realização dos exames clínicos e radiográficos a fim de verificar presença de recidivas. Foram realizadas análises descritivas e estatísticas utilizando o programa Stata/IC versão 14.0 (StataCorp, College Station, TX). Utilizou-se o teste de Mann-Whitney, o teste exato de Fisher e o teste Chiquadrado, além do método de Kaplan Meier e o teste Log-rank para verificar os possíveis fatores prognósticos para as recidivas, adotando-se p<0,05. A amostra foi composta por doze pacientes do gênero masculino (40%) e dezoito do gênero feminino (60%) e a média de idade foi de 37,23 anos (37,23±17,01; 12-77). Dentre as lesões, 22 pacientes apresentavam CO (73,3%), 3 MO (10%) e 5 ameloblastomas (16,7%). A maioria das lesões acometeu a maxila e mandíbula posteriores (93,3%). A recidiva acometeu 7 pacientes (23,3%), sendo todos os casos em CO, com o tempo mínimo de recidiva de 12 meses e máximo de 34 meses e um acompanhamento máximo de 9 anos e 5 meses. Não foi verificado diferença estatística entre os fatores avaliados e o desenvolvimento de recidivas, mas os pacientes que permaneceram com dentes adjacentes a lesão após o procedimento cirúrgico apresentaram tempo menor de recorrência. As curvas de Kaplan-Meier demonstraram um risco acumulado de mais de 80% para recidiva após 29 meses de pós-operatório e após 36 meses de acompanhamento, apenas 37,50% destes pacientes estariam livres de recidivas (p=0,023), além de terem 5,5 vezes mais chances de desenvolver recidivas do que os pacientes que tiveram seus dentes extraídos. O protocolo é efetivo no tratamento das lesões odontogênicas benignas agressivas quando se compara aos tratamentos isolados, como marsupialização e enucleação/curetagem, considerando as mesmas lesões (AU).

Retrospective sectional study with the objective of investigating the occurrence of relapses in aggressive benign odontogenic lesions after the surgical enucleation protocol, followed by peripheral ostectomy and Carnoy's solution. The sample used was of convenience and consisted of thirty patients attended in Oral and Maxillofacial Surgery Department of UFRN between 2008 and 2018. The data were collected through the medical records and then the patients were contacted to perform of clinical and radiographic exams in order to verify the presence of relapses. Descriptive and statistical analyzes were performed using the Stata / IC version 14.0 program (StataCorp, College Station, TX). The Mann-Whitney test, the Fisher's exact test and the Chi-square test, as well as the Kaplan Meier method and the Log-rank test were used to verify the possible prognostic factors for relapses, using p <0 , 05. The sample consisted of 12 male patients (40%) and eighteen female patients (60%) and the mean age was 37.23 years (37.23 ± 17.01, 12-77). Among the lesions, 22 patients had CO (73.3%), 3 MO (10%) and 5 ameloblastomas (16.7%). Most of the lesions affected the posterior maxilla and mandible (93.3%). The relapse affected 7 patients (23.3%), all cases in OC, with a minimum recurrence time of 12 months and a maximum of 34 months and a maximum follow-up of 9 years and 5 months. There was no statistical difference between the factors evaluated and the development of relapses, but patients who remained with adjacent teeth after the surgical procedure presented less recurrence time. Kaplan-Meier curves showed a cumulative risk of more than 80% for recurrence after 29 months postoperatively and after 36 months of followup, only 37.50% of these patients would be free of relapses (p = 0.023), in addition this group were 5.5 times more likely to develop recurrences than patients who had their teeth extracted. The protocol is effective in the treatment of benign aggressive odontogenic lesions when compared to isolated treatments, such as marsupialization and enucleation/curettage, considering the same lesions (AU).

Occupation and factors associated with exposure to the sun among beach workers.

Subjects were selected from five urban beaches to characterize the type of work conducted on urban beaches in the city of Natal, state of Rio Grande do Norte, Brazil, and determine potential associated factors among workers exposed to the sun. Data collection was based on a validated questionnaire. Results were obtained for 362 workers. Individuals were predominantly male (72.6%) who worked under direct exposure to the sun (87.8%). Almost 95% had no more than 6 years of schooling and 87.91% earned an average monthly income of $318.75 dollars or more. Photoprotection was reported by 80.1%, among which sunscreen and caps/hats were predominant. Around 25% smoked and more than half did not consume alcohol. Male gender, no more than 6 years of schooling, daily exposure for up to 6 hours and use of photoprotection were the factors associated with the outdoor work category.

Adoption of photoprotection measures on lip and perioral regions among beach workers in North Brazil.

BACKGROUND: Workers from various occupational groups stand out as being more susceptible to photodamage. Behaviors that can reduce the risk of onset of these disorders include the limitation or reduction of sun exposure, use of photoprotective clothing, and correct use of sunscreen. The present study aimed to verify the use of photoprotection measures by beach workers on the lips and perioral regions, as well as investigate possible associations with sociodemographic, occupational, and health variables. MATERIALS AND METHODS: For this purpose, calibrated researchers applied validated questionnaires. The participants were 362 beach workers with a minimum age of 18 years. Data were analyzed using chi-square tests and robust Poisson regression. RESULTS: In regard to photoprotection measures, most of the population studied reported using some form of protection (80.1%). Among these, the most common were the use of a cap/hat (66.2%) and sunscreen (41.6%). Applying lipstick (3.6%) and using some other measure (4.2%) were the least reported. When compiling a multivariate analysis model, type of work (P = 0.001) was the only variable that explained the adoption of photoprotection measures, regardless of daily and accumulated exposure and the presence of habits. CONCLUSIONS: In general, most workers reported using some form of photoprotection in the oral and perioral regions, and those exposed to direct solar radiation effectively confirmed this.

Desses, 76,8% eram do sexo masculino; 61,6% tinham pele morena ou negra; 94,5% trabalhavam informalmente; e 85,4% trabalhavam expostos ao sol. A maioria (81,1%) relatou uso de algum tipo de fotoproteção: protetor solar (38,7%); protetor labial (15,3%); boné/chapéu (72,4%). Aproximadamente 28% eram fumantes e 48% consumiam álcool regularmente. A fotoproteção com uso de boné/chapéu foi associada à presença de lesões labiais decorrentes da exposição solar. CONCLUSÕES: Observou-se alta prevalência de lesões labiais nos indivíduos expostos ao sol, a qual foi associada ao uso de boné/chapéu como forma de fotoproteção.

OBJECTIVE: To assess the prevalence and factors associated with orolabial lesions caused by sun exposure in beach workers. METHODS: Cross-sectional study with 362 beach workers from five urban beaches in the city of Natal, northeastern Brazil, from August to December 2010. All subjects completed a validated questionnaire to collect personal, occupational, and health-related information and underwent an orolabial clinical examination by trained examiners. Potential associations between sociodemographic, occupational, and health-related variables and the presence of orolabial lesions were assessed using the chi-square test at a 5% significance level. The multivariate analysis was performed using Poisson regression. RESULTS: Of the 362 workers examined, 27.1% had orolabial lesions. Of these, 76.8% were males, 61.6% dark or black skinned, 94.5% informal workers, and 85.4% reported sun exposure. Most (81.1%) reported using sun protection methods including sunscreen (38.7%), lip balm (15.3%), and cap/hat (72.4%). Twenty-eight percent reported smoking and 48% regular drinking. Sun protection with cap/hat was associated with orolabial lesions caused by sun exposure. CONCLUSIONS: There was found a high prevalence of orolabial lesions in workers exposed to sunlight that was associated with the use of a cap/hat as a sun protection method.

Prevalencia de accidentes ocupacionales en estudiantes de odontología de la Universidad Federal de Río Grande del Norte, Brasil / Prevalence of occupational accidents in dental students at the Rio Grande do Norte Federal University, Brazil

El objetivo de este estudio fue determinar la prevalencia de accidentes ocupacionales en estudiantes de Odontología de la Universidad Federal de Rio Grande del Norte (UFRN), Brasil y el nivel de conocimiento de estos sobre exposición ocupacional, medidas preventivas y manejo post exposición. Los datos fueron recogidos a través de un cuestionario, con información referente a edad, género y período cursado, además de la ocurrencia de accidentes ocupacionales, medidas pre y post exposición de 150 estudiantes. Los datos fueron registrados en un banco de datos del Statistical Package for the Social Science (SPSS) 17.0 y sometidos a análisis descriptivo. De los 150 estudiantes evaluados, 45.3% eran hombres y 54.7% mujeres. La prevalencia de accidentes fue de 45.3%, ocasionados por perforación durante el lavado y condicionamiento del instrumental (30.9%) o en procedimientos clínicos (21.8%), por salpicaduras en el ojo (11.8%), contacto directo con sangre (10.9%) y por otras causas (24.6%). De los 68 accidentados, solo 14.7% se realizó exámenes para detectar infección por HBV y/o VIH después del accidente, 86.8% de los estudiantes no recibió ningún tratamiento. De la muestra, 88.7% estaban vacunados contra la hepatitis B y de estos, 48.7% completaron el esquema de vacunación. A pesar de que los estudiantes de Odontología presentaron un adecuado conocimiento sobre medidas preventivas y manejo post exposición, hubo una considerable prevalencia de accidentes ocupacionales e inadecuadas conductas post exposición, reflejando la necesidad de la adopción y/o intensificación de programas preventivos, garantizado el egreso de profesionales con alto nivel de preparación en materia de riesgo laboral.

The aim of this study was to determine the prevalence of accidents in dental students at the Federal University of Rio Grande do Norte (UFRN), Brazil, and the knowledge level about their occupational exposure, preventive measures and post-exposure management. Were collected through a questionnaire, data on age, sex and academic semester, as well as the occurrence of accidents, pre and post-exposure. Were recorded in the database of the Statistical Package for the Social Sciences (SPSS) 17.0 and submitted to a descriptive analysis. Of the 150 students evaluated, 45.3% were men and 54.7% women. The prevalence of accidents was 45.3%, caused by drilling in the wash of instrumental (30.9%) or dental procedures (21.8%), due to splash in the eye secretion (11.8%), direct contact with blood (10.9%) and other causes (24.6%). Of the 68 victims, only 14.7% were tested for HBV infection and / or HIV and after the accident, 86.8% of students did not undergo any treatment. Of the sample, 88.7% were vaccinated against hepatitis B and of these 48.7% completed the vaccination schedule. Despite the dental students have an adequate knowledge of preventive measures and post-exposure management, there was a considerable prevalence of occupational accidents and inappropriate behavior after exposure, reflecting the need for adoption or intensification of preventive programs, ensuring the egress of professionals with a high level of preparedness in biohazard.
