Application of basic science to clinical problems: traditional vs. hybrid problem-based learning.

It is widely acknowledged that clinical problem-solving is a key skill for dental practitioners. The aim of this study was to determine if students in a hybrid problem-based learning curriculum (h-PBL) were better at integrating basic science knowledge with clinical cases than students in a traditional, lecture-based curriculum (TC). The performance of TC students (n=40) was compared to that of h-PBL students (n=31).

Comparison of the Bolton Standards to longitudinal cephalograms superimposed on the occipital condyle (I-point).

Objective: To compare traditional superimposition on sella turcica and the anterior cranial base (SACB) to superimposition referenced at the occipital condyle (I-point) for demonstrating craniofacial growth and development.

Materials And Methods: Tracings for ages 8, 10, 12, 15 and 18 were chosen from the Bolton Standards of Dentofacial Developmental Growth to compare superimposition with the traditional longitudinal reference at SACB (anterior curvature of sella turcica and anterior cranial base) to reference at I-point on the antero-inferior contour of the occipital condyles in norma lateralis. The serial tracings were superimposed using both the sagittal and postero-anterior (PA) tracings.
