Validity and reliability of the Persian version of the short-form child perceptions questionnaire 11-14-year-old children (CPQ11-14).

Background: The Child Perception questionnaire 11-14 (CPQ 11-14) is an efficient tool for assessment of oral health-related quality of life (OHRQoL). This questionnaire has been briefed to 16 items (CPQ11-14 ISF-16) to facilitate its employment. The purpose the present study was to translate CPQ11-14 ISF-16 to Persian language, culturally adapt, and initially evaluate its among adolescent population.

The impact of age mimicry bias on the accuracy of methods for age estimation based on Kvaal's pulp/tooth ratios: a bootstrap study.

Introduction: Methods based on pulp/tooth ratios proposed by Kvaal et al. (1995) have been widely used for age estimation in adults. The tendency of age estimates to mimic the age structure of the reference population, i.

Effect of high concentration nano-hydroxyapatite serum on shear bond strength of metal brackets following three different enamel surface preparation methods: An in vitro study.

Objective: White spot lesion (WSL) is one of the most important complications of fixed orthodontic treatment. Many methods have been studied to prevent this problem. This study is aimed to investigate the effect of high concentration nano-hydroxyapatite (nHAP) on shear bond strength (SBS) of metal brackets and Adhesive Remnant Index (ARI) score in different preparation methods.

ACR Appropriateness Criteria® pre-irradiation evaluation and management of brain metastases.

Pretreatment evaluation is performed to determine the number, location, and size of the brain metastases and magnetic resonance imaging (MRI) is the recommended imaging technique, particularly in patients being considered for surgery or stereotactic radiosurgery. A contiguous thin-cut volumetric MRI with gadolinium with newer gadolinium-based agents can improve detection of small brain metastases. A systemic workup and medical evaluation are important, given that subsequent treatment for the brain metastases will also depend on the extent of the extracranial disease and on the age and performance status of the patient.

Stereotactic ablative body radiotherapy (SABR) for effective palliation of metastases: factors affecting local control.

We analyzed factors associated with inferior local control following stereotactic ablative body radiotherapy (SABR) for palliation of metastases. We reviewed records of patients receiving SABR for metastases at Duke University from 2006-2010. Biologically effective dose (BED) was calculated using the linear-quadratic model.
