RESUMO

The purpose of the study is to evaluate the survival rate of pterygoid implants compared to implants placed in different maxilla area and to settle as an alternative solution for the rehabilitation of the posterior maxilla atrophy. Studies that were included for this systematic review were selected using different database of references: PubMed Medline, Lilacs and Cochrane Library. Other journal platforms were also used for the research. Five articles met the strict inclusion/exclusion criteria of the 180 articles founded. This systematic review was registered on Prospero (CRD42023409706) and followed PRISMA statement. A total of 768 implants placed presented 97.43 % with a peak of 100 % of survival rate. Follow-up period varies from a minimum of 1 year to a maximum of six years. Pterygoid implants could be a valid alternative in patients presenting a posterior maxilla atrophy, but results should be interpreted cautiously due to the difficulty of the surgical technique. Further studies in the future should be taken in consideration to confirm the success rate of pterygoid implants since there is only one prospective RCT, potentially incorporating modern technologies such as guided surgery or navigated surgery could be a solution for the success of pterygoid implants, minimizing the risk and less dependent on the operator.

RESUMO

INTRODUCTION: The aim of this study was to evaluate and compare the clinical efficacy of diode laser and ozone gas in the treatment of dentin hypersensitivity (DHS). METHODS: One hundred thirty-two teeth from 44 patients with moderate DHS were randomized into 3 groups according to a split-mouth design. In the diode laser group, the operator irradiated the superficial dentin exposed with an 808-nm wavelength and incremental power from 0.2 to 0.6 W with a 20-second interval. In the ozone gas group, the operator applied a high dose of ozone (32 g/m3) for 30 seconds using a silicon cup. In the placebo group, no therapy was applied. The dentin sensitivity level was evaluated upon enrollment (T0), immediately after treatment (T1), 3 months post-treatment (T2), and 6 months post-treatment (T3) with a cold air blast challenge and tactile stimuli. The pain severity was quantified according to the visual analogue scale. The Wilcoxon signed rank test was used to scrutinize potential statistical disparities among the treatments. Statistical significance was predetermined at P < .05. RESULTS: A significant decrease of DHS was observed in the ozone gas group and the `diode laser group immediately after treatment and after 3 and 6 months of the therapy. After 6 months from the therapy, the sensitivity values in the teeth treated with ozone gas remained statistically lower than those treated with diode lasers (P < .05). CONCLUSIONS: A laser diode and ozone gas are both efficient as dentin sensitivity treatment. Ozone maintains an invariable effectiveness after 6 months.
