Evaluation of Shear Bond Strength of Orthodontic Brackets Bonded with Different Adhesives.

Background: To endure the orthodontic forces used throughout treatment, the bond strength of bonded orthodontic brackets must be enough with assessment of shear bond strength when bonding orthodontic brackets with various adhesives.

Materials And Methods: Overall, forty extracted premolars due to orthodontic treatment were included. They were split into four equal cohorts with various primers.

Effect of Excess Fluoride Exposure on Radiographic and Histopathological Changes in Long Bones of Rabbit.

The present study aimed to investigate the effects of excess fluoride exposure on long bones in young rabbits (Oryctolagus cuniculus). New Zealand White rabbits (n = 30) were randomly divided into five equal groups and were provided drinking water containing 0, 50, 100, 200, and 400 µg added fluoride per ml ad lib for a period of 90 days. Blood samples were collected on days 0, 45, and 90 of the experiment, and femur samples were collected for fluoride estimation on day 90 after radiography of long bone before sacrifice.

Toxic effect of sodium fluoride on hydroxyproline level and expression of collagen-1 gene in rat bone and its amelioration by L. fruit pulp extract.

Excessive fluoride intoxication plays an important role in the development of dental, skeletal and non-skeletal fluorosis. The aim of this study was to ascertain the toxic effect of excessive fluoride ingestion on the level of hydroxyproline and expression of type 1 collagen gene in rat bone and its amelioration by supplementation with fruit pulp extract. Forty albino rats were randomly assigned to four groups.

Assessment of Bite Force in Patients Treated with 2.0-mm Traditional Miniplates versus 2.0-mm Locking Plates for Mandibular Fracture.

The objective of this study is to analyze the difference in bite forces in patients treated for mandibular fractures with 2.0 mm conventional and locking titanium plating system. A randomized study was performed for the treatment of fractures of mandible.

Effect of concentrates restriction on feed consumption, diet digestibility, and nitrogen utilization in captive Asian elephants (Elephas maximus).

In order to study the effect of concentrates restriction on feed consumption, diet digestibility, and utilization of nitrogen in captive Asian elephants (Elephas maximus), two feeding trials were conducted on three juveniles, four sub-adults, and three adults. During trial I, the conventional zoo diets of juveniles, sub-adults, and adult contained 22, 17, and 16% of concentrates on dry matter (DM) basis, respectively. During trial II, the amount of concentrate was reduced by 50%.
