A sociedade contemporânea impõe desafios constantes aos setores da saúde e da educação, alicerçada em revisões e reformulações permanentes para formação de recursos humanos. Este artigo promove uma revisão crítica da literatura a respeito da aprendizagem baseada em problemas (Problem Based Learnig - PBL) direcionada ao ensino da Odontologia. As bases de dados consultadas foram Medline (via EBSCO), SCIELO, BBO e LILACS (via BVS). As palavras-chave foram definidas baseadas em artigos previamente selecionados. Esta metodologia se apresenta como uma alternativa para formação e educação em Odontologia. É considerada uma ferramenta de trabalho para professores que buscam desenvolver em seus alunos capacidades cognitivas promotoras do desenvolvimento do raciocínio clínico integrado, com perfil direcionado à educação permanente

OBJECTIVE: To evaluate the effectiveness of tooth brushing supervision in one or more sessions on dental plaque removal and toothbrush wear. MATERIAL AND METHOD: 3- to 5-year-old children received new toothbrushes and attended a puppet theater about oral health. Forty-nine children were randomly selected and divided into 3 groups (GI=20; GII=14; GIII=14). Fones' brushing method was demonstrated to the GI and GII groups to evaluate the following: the professional direct supervision and tooth brushing training in five sessions (GI), the professional direct supervision and a one-training session (GII) and the puppet theater influence only (GIII-control group). The dental plaque index (IPL) was recorded at baseline (T0), after 24 days (T1) and after 46 days (T2) and toothbrush wear (ID) was recorded on T1 and T2. The Kruskal-Wallis test and the Friedman test (IPL), as well as the one-way ANOVA and the paired Student's t-test (ID) (p<0.05) were employed to analyze the data. RESULT: GI showed a significant difference from the others groups in T1 and T2 (p<0.01).The index of toothbrush wear increased (p<0.0001) from 24 days (0.52±0.35mm) to 46 days (0.90±0.48mm), but there was no significant association between toothbrush wear and plaque index for T1 (r=0.230-p= 0.116) as well as for T2 (r=0.226-p=0.121). CONCLUSION: The multiple sessions of professional supervision were effective to reduce the dental plaque index, which was not influenced by toothbrush wear, showing continuous oral hygiene motivation needs.

The present study aimed to discuss the etiology, diagnosis, prevalence and treatment of mesiodens based on current scientific evidence. Two clinical cases of patients of the pediatric dentistry clinic, both with complaints of dissatisfaction with their smile for showing "strange teeth", were presented. After the clinical, radiographic and tomographic diagnosis, the presence of supernumerary teeth (mesiodens) was diagnosed. The treatment consisted in the surgical removal of the supernumerary teeth and subsequent referral to orthodontics to proceed towards recovering adequate aesthetics and function. The removal of mesiodens in children has the purpose of avoiding possible aesthetic and functional disorders resulting from the presence of the pathology allied to the favorable prognosis in early age.

Background Fluoride plays an important role in the control of dental caries. Aim To evaluate the chemical exchange between restoration of glass ionomer cement of high viscosity (GIC) and primary dentin with application of sodium fluoride (NaF) 2% through changes in hardness from uptake of calcium, phosphate and fluoride. Material and method Class I cavities were prepared in 40 sound primary molars, and the sample was divided into two groups (n=20) according to dentin condition: sound (1) and demineralized (2). Sub-groups (n=10) were formed to investigate the isolated action of the GIC or the association with NaF (F). This in vitro study examined the chemical exchange under two conditions, sound and demineralized dentin (pH cycling), to simulate the occurrence of mineral loss for the caries lesion. G1 and G2 received GIC restoration only; groups G1F and G2F received NaF before GIC restoration. The specimens were prepared for Knoop hardness test and micro-Raman spectroscopy. A two-way ANOVA test (α = 0.05) was used for statistical analysis. Micro-Raman data were qualitatively described. Result Increased hardness was observed in all the sites of direct contact with GIC in sound and demineralized dentin for all groups (p<0.001); no difference was observed in microhardness after application of NaF (p>0.05). In the evaluation of micro-Raman, direct contact between GIC and dentin for sound and demineralized dentin resulted in increased peaks of phosphate. Conclusion The exchange between GIC and demineralized dentin may induce changes of mechanical properties of the substrate, and uptake of mineral ions (phosphate) occurs without the influence of NaF.

The technique using CTZ paste (chloramphenicol, tetracycline, and zinc oxide-eugenol) in the endodontic treatment of deciduous teeth is easy to perform and requires a single session, which is an advantage with child patients. The inexistence of clinical protocols with the use of CTZ and the multifactorial endodontic repair process in deciduous teeth evidence the need for research on the subject. This study aimed to suggest a clinical protocol model for the systematization and standardization of the endodontic treatment of deciduous teeth using CTZ paste. In the case report presented, after pulp therapy, clinical-radiographical follow-up was conducted after 30, 60, 90 and 180 days. It was concluded that using CTZ paste is a simple, viable, and satisfactory alternative. Future clinical studies are needed regarding CTZ use in child clinic with strong scientific evidence.
