Microscopic evaluation of rotatory and handle caries removal on glass ionomer cement/dentin interface

Aim: This study evaluated the interface between glass ionomer cement (GIC) and dentin using the conventional and atraumatic restorative treatment (ART) techniques for removal of decayed tissue. Materials and Methods: After preparation of the cavities by the conventional (Group I ­ GI) and ART (Group II ­ GII) techniques, the specimens were divided into 3 subgroups according to the GIC used (n=10). The conventional GIC KETAC FILL (3M/ESPE) was used in the groups GI-1 and GII-1, the conventional GIC VIDRION R (SS WHITE) in the groups GI-2 and GII-2, and the modified GIC FUJI II LC (GC Corporation) in the groups GI-3 and GII-3. For the microscopic analysis, the teeth were decalcified in a solution containing equal portions of 50% formic acid and 20% sodium citrate, dehydrated and submitted to paraffin baths. The samples were sectioned (6m in thickness), stained by the Brown and Brenn method, and evaluated in a light microscope. Results: The microscopic analysis revealed interaction between the material and dentin structure only with the FUJI II LC. In addition, the behavior was superior for the conventional technique in comparison to the ART technique. Conclusion: It was concluded that the technique used for carious dentin removal does not seem to be determinant for the bonding of ionomeric materials to the dental structure, except for the resin-modified GIC in which the formed hybrid layer was higher using the conventional technique

A educação em saúde como medida de prevenção e promoção da saúde bucal / Health education as a measure of prevention and promotion of oral health

O objetivo deste estudo foi conhecer os projetos desenvolvidos na área de educação em saúde nas escolas públicas, bem como aceitação de pais, educadores e alunos. Foi feito um estudo epidemiológico quantitativo. A população estudada foi constituída de crianças do sexto ao nono ano do ensino fundamental, seus respectivos responsáveis e professores. A maioria dos participantes aceitaram o projeto de educar em saúde. Os professores afirmaram que 70% dos alunos demonstram interesse pelo tema de educação em saúde bucal. Os entrevistados se puseram dispostos a participar de um programa em conjunto envolvendo pais, professores e alunos. Todos os professores participantes consideraram essa integração importante, podendo ocorrer, principalmente, através de projetos pedagógicos. O grupo estudado, além de obter mais conhecimento em saúde bucal, também destacou a importância da presença dos alunos de Odontologia da UEA na escola...

The objective of this study was to get to know health education projects developed in public schools, as well as to assess acceptance of parents, educators, and students. The study samples was composed by students from sixth to ninth grade; their guardians and teachers. Most participants accepted well the health education project. Teachers stated that 70% of students were interested in oral health education. Respondents stood ready to participate in a joint program between parents, teachers and students. All teachers considered this integration important, and pointed out the possibility of it occurrence mainly through educational projects. The studied group, gained knowledge on oral health, and highlighted the importance of the presence of dentistry students from UEA at the school...
