background and aims. this in vitro study was designed to evaluate the effect of composite resin types and orthodontic debonding pliers on the amount of adhesive remnants and enamel damages using a novel method of measurement. materials and methods. 120 extracted human premolars were randomly divided into four groups (n = 30). the standard edgewise metallic brackets were bonded to the teeth with...

An improved formula for the timing of binary pulsars that accounts for the relativistic deflection of light in the gravitational field of the pulsar’s companion is presented, and the measurability of this effect together with its variance estimates are discussed. The deflection of the pulsar’s beam trajectory in the gravitational field of its companion leads to variation in the pulsar’s rotatio...

C II malocclusion, which affects approximately one-third of patients seeking orthodontic treatment, often reflects both dental and skeletal deviations from the norm.1-3 Because it frequently involves excessive overjet,4 it is easily recognized by lay persons, leading to its overrepresentation in orthodontic practices. According to the National Health and Nutrition Estimates Survey III, in which...

Treatment of skeletal Class III patients at younger age is highly unpredictable. The patient may respond well to the treatment or may show excessive mandibular growth during growth spurt which may require orthognathic surgery later on. If not treated at earlier stages of life, the condition may worsen with time. This case report will present the comprehensive orthodontic management of a 9-year-...
