Abstract The aim of this study was to evaluate the peri-implant bone loss of External Hexagon (EH) and Morse Taper (MT) implants in patients wearing immediately loaded mandibular overdentures during a 1-year follow-up. This is a non-randomized controlled clinical trial including 18 MT and 22 EH implants. Periapical radiographs were taken after overdentures insertion and following 1 year. The peri-implant bone loss was assessed through digitalization and analysis of the radiographs in the software Corel DRAW X7. For this, measurement from implant platform to residual ridge at mesial and distal surfaces of each implant was conducted. The results showed high success rate in the groups EH (100%) and MT (94.4%). For peri-implant bone levels, it was found significant difference between the groups (p=0.032) and greater bone loss was observed in the group EH. In general, bone loss was 0.85mm (±0.82) for EH and 0.10mm (±1.0) for MT. It was concluded that greater bone loss occurred in the group EH in comparison to the group MT after a 1-year follow-up.

Objective: To compare two fluorinated varnishes for the control of white spot lesions.Material and Methods: A randomized controlled clinical trial was conducted. A total of 103 active whitespot lesions on permanent upper anterior teeth from 24 patients, aged 7 to 9 years were randomly assigned totwo groups, G1: Duraphat® (n=52) and G2: DuraShield® (n=51). Weekly applications were perform for fourconsecutive weeks. Fifth week the dimension, regression and activity of the lesions were evaluated. Student’sT test, Wilcoxon Ranks and Chi square were used at 5% significance. Results: At the end of the study, the lesion reduction was observed in 69.7%, finding significant differences(p<0.05) in the mean of the initial and final dimensions in general (2.74 mm to 1.91 mm) and in each group, G1(2.84 mm to 2.03 mm), G2 (2.64 mm to 1.78 mm). In the activity of the lesions, it was found in the G1, 12 active and6 inactive lesions; while in G2, there were 14 active and 29 inactive; these differences were significant (p<0.05). Conclusions: The two evaluated products showed similar clinical efficacy in the remineralization of activewhite spot lesions after 4 weeks of therapy.
