Objective: To determine the frequency of the stylohyoid complex calcification in digital panoramic radiographs of a radiological center. Methods. The type of study was qualitative, descriptive, cross-sectional and retrospective design; 400 digital panoramic radiographs between the ages of 25 and 70 were analyzed. A visual evaluation of the digital panoramic radiographs was performed to assess the type and pattern of the stylohyoid ligament calcification. Results. The 56.8% presented calcification of the stylohyoid complex in digital panoramic radiographs; according to sex in the female group it was present in 64.6%; Regarding the age group, 65.8% presented calcification in adults aged 30-59 years-old; According to the affected side, 71.4% were bilateral, according to the radiographic appearance, type I presented a higher frequency with 50.1% on the right side and 62.5% on the left side. ...

 Objectives: Compare the impact of an aerated beverage on the surface microhardness of three nanofilled composite resins (Filtek Z250 XT, Filtek Z350 XT and Tetric N - Ceram) evaluated in-vitro. Materials and Methods: This study was applied, analytical, experimental and longitudinal. 48 cylinders (16 cylinders per evaluated composite resin) of 6mm x 4mm, were made, which divided into two subgroups of 8 cylinders; and stored in physiological serum. These were submitted to the effect of Coca-Cola for 10 minutes per day and stored in physiological serum until the next immersion (24 hours); for 7 days. Data analysis was performed using Stata ® 12 Software. The ANOVA means test was applied.. Results: Displayed that the Filtek Z250 XT had a higher surface microhardness value, before (72.93 HV ±4.62) and after the erosive challenge (62.65 HV ±3.42); while Tetric N – Ceram was the resin wi...

Objectives: To determine the position of the mental foramen evaluated in panoramic radiographs in a radiological center, Lima 2022. Materials and Methods: A descriptive, cross-sectional and retrospective investigation was carried out; which consisted of a sample of 276 digital panoramic radiographs. The position of the mental foramen was evaluated using the observation technique, using the All Jasser classification for the horizontal dimension, as well as the Parmani classification for the vertical dimension; In addition, the analysis was carried out by descriptive statistics to measure the frequencies and percentage. Results: It was observed that the most prevalent mental foramen position was between the lower premolars in the horizontal dimension with 49.3% on the right side and 52.9% on the left side and in the vertical dimension the position of the mental foramen more The prevalence ...
