The objective of this study is to question the existence of a possible relationship between obesity and temporomandibular joint disorders. ⋯ There was no statistically significant difference between body mass index and temporomandibular joint disorders frequency, but further larger studies will give more accurate outcomes.

The role of monocytes and high-density lipoprotein (HDL) levels in the pathophysiology of cardiovascular disease (CVD) is well known. However, the relationship between monocytes to HDL-cholesterol ratio (MHR) and CVD in chronic obstructive pulmonary disease (COPD) patients has not been investigated previously. We, therefore, aimed to investigate the predictor role of MHR in the development of CVD in subjects with COPD. ⋯ MHR is significantly associated with CVD in COPD patients. Further prospective studies are warranted to elucidate the predictive value of MHR in COPD patients.

There were no comparing data about the effect of recently developed file system OneCurve on apical debris extrusion. ⋯ Under the conditions of this in vitro study, ProTaper-Next, 2Shape, and OneCurve files had similar apical debris extrusion values. Cervical preflaring of root canals did not affect the amount of apically extruded debris.

The purpose of this study was to observe the stresses of all-on-four implant designs in an edentulous mandible in the implant, surrounding bone, and monolithic ceramics. ⋯ In bilateral loading, the force applied to anterior implants does not have a significant effect on the bone structure. Stress concentration increases in posterior angled implants and surrounding bone. Moreover, stress concentration increases as the length of the cantilever, the weakest part in all-on-four implants, increases. As posterior implant angulation increases, stress concentration level and localization are affected.
