Avaliação do conhecimento prévio e adquirido sobre cárie dentária em graduandos de Odontologia da Universidade Federal do Espírito Santo ­ UFES / Evaluation of previous and acquired knowledge about dental caries from undergraduate dentistry students from the Federal University of Espirito Santo ­ UFES

Objetivo: Avaliar conhecimento prévio e adquirido sobre cárie dentária de graduandos em Odontologia da Universidade Federal do Espírito Santo ­ UFES. Material e Métodos: Este estudo exploratório teve como grupo amostral (N = 121) acadêmicos de Odontologia do 1o ao 8o períodos. Um questionário sobre os conhecimentos prévios e adquiridos sobre cárie dentária foi aplicado aos estudantes. A análise dos dados foi realizada de forma descritiva (frequências absolutas e relativas) e analítica (testes qui-quadrado e McNemar; p < 0,05). Resultados: Foi observado que quanto ao conceito da cárie dentária, 52,9% adquiriram de 1ª a 4ª séries, e 31,4% de 5ª a 8ª séries. Maior parte do conhecimento obteve-se da graduação em Odontologia (38,8%), da casa/família (28,1%) e dentista particular (13,2%). Os alunos afirmaram que o conhecimento foi aplicado na prática diária (90,1%) e melhorou a própria saúde bucal (95,0%). Foi observada diferença significativa nas respostas quanto à consequência da cárie dentária e necessidade de restauração entre alunos do início do curso (1º período) e do meio e final do curso (4º e 8º períodos) (qui-quadrado; p < 0,05). No entanto, não houve diferença estatística entre os alunos do 4º e 8º períodos. Quanto ao conhecimento sobre cárie dentária dos acadêmicos do 4º período "antes" e "após'' a inserção no curso de Odontologia, observou-se melhora estatisticamente significante após o ingresso na faculdade (McNemar; p < 0,05). Conclusão: Estudantes passaram adquirir conhecimento efetivo sobre cárie dentária somente após ingressarem na faculdade, tornando-se evidente após o 4º período do curso. Houve relevância das informações coletadas com prática de saúde bucal.(AU)

Aim: To evaluate the knowledge about dental caries that had been acquired both previously and during the undergraduate Dentistry course at the Federal University of Espírito Santo (UFES). Methods: This exploratory study was conducted with a sample group (n = 121) of undergraduate Dentistry students from the first to eighth semesters. A questionnaire about the knowledge of dental caries acquired before and during the Dentistry course was applied to the students. Data was analyzed by descriptive (absolute and relative frequencies) and analytical (chi-square test and McNemar test; p < 0.05) statistics. Results: It was observed that 52.9% of the students had learned about the concept of caries in elementary school, while 31.4% reported having learned about the concept during middle school. A large percentage of the students (38.8%) responded that they had acquired most of their knowledge about dental caries during Dental School, while 28.1% and 13.2% stated that it was from their home/family and private dentist, respectively. For 90.1% of the students, their knowledge about dental caries is used on a daily basis, and 95% reported that this knowledge improved their oral health. A significant difference was observed in the responses from first-year students (first period) when compared to the students from the middle (fourth period) and final (eighth period) years of the course as regards the consequences of dental caries and the need for restoration (chi-square, p < 0.05). However, no statistical difference was observed between fourth and eighth periods. Comparing the overall knowledge about dental caries before and during dental school, a significant improvement was observed only after the fourth period (McNemar test, p < 0.05). Conclusion: Relevant knowledge about dental caries was mostly acquired by the students during dental school, especially after the fourth period. Relevance from the collected data and improvement of oral self-care were also observed.(AU)

Cleaning solutions as a cause of diffuse lamellar keratitis.

PURPOSE: To assess the capability of two microkeratome cleaning solutions in causing diffuse lamellar keratitis (DLK) in a rabbit model of laser in situ keratomileusis (LASIK). METHODS: Two cleaning solutions (Palmolive 2:100 and Cidezyme 2:250) were tested. These solutions were diluted with balanced salt solution according to directions from the Hansatome microkeratome manual. Two additional solutions were prepared using an additional ten-fold dilution, creating a total of four study solutions. A LASIK flap was created in one eye each of 25 rabbits using the ALK Chiron microkeratome. The rabbits were divided into five study groups. The flaps were reflected and a drop of one of the study solutions (or BSS, control group) was placed on the interface. After 1 minute, the solution was washed out from the interface and the flap was repositioned. The eyes were examined at the slit lamp on postoperative days 1, 2, 3, 5, and 7. RESULTS: In 12 eyes, a flap displacement was identified. Four eyes showed flap retraction and five others, epithelial ingrowth in flap margins. The incidence of these events did not differ among groups. Thirteen eyes were then evaluated for DLK. No DLK-like interface inflammation was seen in the studied eyes. CONCLUSION: The cleaning solutions, when diluted as recommended by the microkeratome manufacturer, when in contact with the corneal stroma, and provided that the interface was washed with BSS did not cause DLK interface inflammation in rabbit LASIK models.
