Evaluating the relation of posterior occlusal plane to ala-tragal line according to age and sex.

Occlusal plane orientation affects the esthetic, function, and success of removable or fixed prostheses. The most prevalent index for determination of this plane is the ala-tragus line while there are controversies in the exact location of tragus reference point.

Effect of beverages on the hardness and tensile bond strength of temporary acrylic soft liners to acrylic resin denture base.

Statement Of Problem: Two potential problems commonly identified with a denture base incorporating a resilient liner are failure of the bond between acrylic resin and soft liner material, and loss of resiliency of the soft liner over time. Since patients may drink different beverages, it is important to evaluate their effects on physical properties of soft lining materials.

Purpose: The objective of this in vitro study was to evaluate the effect of different beverages on the hardness of two temporary acrylic-based soft lining materials and their bond strength to the denture base resin.

Effect of gravity and capillarity on human saliva penetration in coronally unsealed obturated root canals.

Aim: The purpose of this study was to evaluate the effect of gravity and capillarity on penetration of human salivary bacteria into the entire length of obturated root canals, and to demonstrate the dye penetration configuration.

Materials And Methods: Fifty single-rooted premolars were decoronated, prepared to a standardized length of 15 mm, instrumented, and randomly divided into two groups (A and B) of 25 teeth each. Each group consisted of experimental (15 samples) and negative and positive controls (five samples each).

Comparison of the mandibular bone densitometry measurement between normal, osteopenic and osteoporotic postmenopausal women.

Objective: This study was conducted to compare the mandibular bone density between postmenopausal women with normal skeletal bone mass density (BMD) and those with low skeletal BMD using digital panoramic radiographs.

Materials And Methods: One hundred fifteen postmenopausal women were divided into normal and osteoporotic/osteopenic groups. Digital panoramic radiographs were prepared using Digora PCT Sorodex equipment and Promax panoramic X-ray unit (Planmeca, Helsinki, Finland, Kvp=68 and mA=9).
