Cleft lip and palate (CLP) is the most common congenital facial anomaly. About 70% of all the CLP cases and 50% of cleft palate only fall within non-syndromic pathologies. The purpose of this report was to show the clinical management of initial obturator therapy from birth to 3 months. The obturator was fabricated from the conventional orthodontic acrylic materials with cold polymerization (OrtoPoli, Polident, Slovenia). For successful treatment of cleft lip and palate patients, during the planning of prosthetic therapy one should take into consideration the deformation of maxillary segments\, as well as the disproportion between the upper and lower jaw alveolar ridge. Well planned prosthetic therapy will result in satisfactory function and aesthetics of a cleft palate patient.

Objective: Evaluated the effects of desensitizing dentifrices on dentinal tubule occlusion in human teeth thought qualitative and quantitative analysis. Methods: Eighty dentin block were divided in eight groups, two controls (positive and negative) and six using desenstitizing dentifrices (Colgate Pro-alívio®, Colgate Tripla Ação®, Colgate Sensitivity®, Sensodyne Repair & Protect®, Sensodyne dentes sensíveis® and Cariax®) The specimens were storaged in natural saliva. A simulated toothbrushing machine were used corresponding 21 brushings weekly and used six cicles. For qualitative analysis Scanning Eletronic Microscopy (SEM) and Energy-Dispersive X-ray Epectroscopy (EDS) were used. Percentage of occluded tubules was obtained for quantitative analisys. The data were statistically analyzed by ANOVA and Tukey tests (p < 0.05). Results: Colgate Pro-alívio®, Colgate Sensitivity®, Sensodyne Repair & Protect® and Sensodyne dentes sensíveis® showed better effect in occluded dentinal tubules (p<0.05), the slurry on dental surface were differents depending of active principle of samples and EDS showed presence of calcium and phosphorus in all groups. Conclusion: All dentifrices were able to occluded dentinal tubules and Calcium and phosphorus were a regular found, however Cariax® andColgate Tripla Ação® had the worst results in quantitative analyses.

Solitary median maxillary central incisor syndrome (SMMCI) is a complex disorder consisting of multiple, mainly midline, defects of development resulting from unknown factors and an uncertain etiology. SMMCI tooth itself is chiefl y an esthetic problem. This case report is an esthetic resolution for a 9- year-old girl with SMMCI as suggested and diagnosed for the first time by a team of dentists. The patient presented the philtrum of her upper lip indistinct, the maxillary labial frenum absent and a single median maxillary central incisor, with symmetrical crown form. Thus, the dentist group contacted her pediatrician reporting these findings and suggesting the diagnosis of SMMCI. The proposed dental treatment was the movement of the central incisor and the right lateral incisor for a better alignment by using some mobile orthodontic appliances and recontouring this lateral tooth with composite. The esthetical finish result pleased the patient as well as her parents.

Background: In the area of education research, it is well-known that studies of a defined question are seldom replicated. Furthermore, e-learning resources with evidence-based content in dentistry have received relatively little attention from researchers. The Context and Purpose of the Study: The aim of this clinical study was to evaluate how dentistry students from two consecutive cohorts in their first clinical semester rate a long-standing evidencebased dentistry (EbD) resource in an e-learning environment using a questionnaire of 43 specific items on 1) general questions regarding user-friendliness and acceptability, as well as 2) specific questions on content and functional range (A), handling and technical aspects (B), and didactics and educational value(C) based on a Likert scale from 0 = ‘strongly disagree’ to 3 = ‘strongly agree’, and how this compares to a primary study in which the resource was addressed as a novelty. The data were analyzed statistically using a one-way ANOVA followed by a Kruskal-Wallis multiple-comparison Z-test. Results: A response rate of 100% was achieved. The majority of the users thought the topic of EbD to be important. The e-learning resource was rated with a score of 2.40 ± 0.66 (on a Likert scale from 1-6 where 1 = “very good” and 6 = “insuffi cient”). 86.15% of the students stated that they consider the resource beneficial for their study in clinical simulation and in patient treatment courses. The results averaged for A: 1.92 (±0.57; median: 1.928), B: 1.48 (±0.60), and C: 2.27 (±0.67). The obtained results in the replication study showed no statistical significant differences to the primary study. Conclusions: The e-learning resource with dentistry vignettes cases and learning components on evidence-based principles was consistently rated positively by the students. Owing to their agreement with the data of the primary study, the results of the present study point to the remarkable validity of the method of evaluation. This should be addressed in future studies with larger cohorts.
