Factors affecting career decision-making of stomatology undergraduate students in China at graduation: a cross-sectional study on selection dilemmas.

Background: Given today's competitive climate, graduates in stomatology face the dilemma of deciding whether to pursue higher education, obtain a master's degree, or focus on clinical careers. However, their career planning tendencies and decision-making factors have not been clarified. This study aimed to analyze these aspects among stomatology undergraduate students at the Southwest Medical University (SWMU) in China.

Nocturnal Blood Pressure Estimation from Sleep Plethysmography Using Machine Learning.

Background: Elevated nocturnal blood pressure (BP) is a risk factor for cardiovascular disease (CVD) and mortality. Cuffless BP assessment aided by machine learning could be a desirable alternative to traditional cuff-based methods for monitoring BP during sleep. We describe a machine-learning-based algorithm for predicting nocturnal BP using single-channel fingertip plethysmography (PPG) in healthy adults.

Should the vent hole of posterior implant crowns be placed on the lateral surface? An in vitro study of the hydrodynamic feature of cement extrusion and retention ability.

Although placing a vent hole on the occlusal surface of the implant crown can reduce cervical marginal cement extrusion, it has disadvantages. Transferring the hole to the buccal or lingual surface of the posterior implant crown could therefore be an alternative solution. This study investigated the effect of transferring the vent hole to the lateral side of the implant posterior crown on the hydrodynamics of excess cement extrusion and the crown's retention ability.

Evaluation of sealing efficacy and removal convenience of sealing materials for implant abutment screw access holes.

Background: Sealing materials are used to fill abutment screw access holes (SAH) to prevent microleakage and protect the central screws in oral implant restoration. However, thus far, no consensus has been reached on sealing material selection. In this study, a comparison of the sealing efficacy and removal convenience of different sealing materials for cement-retained implant restoration was conducted.
