A Comparative Assessment of the Upper Pharyngeal Airway Dimensions among Different Anteroposterior Skeletal Patterns in 7-14-Year-Old Children: A Cephalometric Study.

Background: The pharyngeal airway is a crucial part of the respiratory system's function. Assessing the pharyngeal airway dimensions in different skeletal types is important in the orthodontic treatment of growing patients. The aim of this study was to compare the upper pharyngeal airway dimensions of 7-14-year-old children with different skeletal types.

Orthodontic tooth movement and root resorption in ovariectomized rats treated by systemic administration of zoledronic acid.

Introduction: The effect of zoledronic acid, a potent and novel bisphosphonate, on tooth movement and orthodontically induced root resorption in osteoporotic animals systemically treated with zoledronic acid as similarly used in postmenopausal patients has not been elucidated. Therefore, this study was undertaken.

Methods: Fifteen 10-week-old female Wistar rats were divided into 3 groups: ovariectomy, ovariectomy + zoledronic acid, and control.

Tooth movement and root resorption; the effect of ovariectomy on orthodontic force application in rats.

Objective: To quantify the amount of tooth movement and orthodontically induced root resorption (OIRR) in ovariectomized rats.

Materials And Methods: Five 10-week-old female Wistar rats undergoing ovariectomy (OVX) were investigated as the experimental group, and the other five without ovariectomy served as the control group. Four weeks after ovariectomy, 25-g nickel-titanium closed-coil springs were applied mesially to the maxillary left first molars.

Periodontal status and orthodontic treatment need of autistic children.

Aim: To evaluate the periodontal status and orthodontic treatment need of autistic children and compare these findings to nonaffected, same-age individuals.

Method: The periodontal status and orthodontic treatment need were evaluated in 32 autistic and 48 nonautistic boys and girls age 8 years to 12 years (mean 9.7 ± 1.

Interleukin-1beta levels, pain intensity, and tooth movement using two different magnitudes of continuous orthodontic force.

This study aimed to determine the optimum orthodontic force from a broader perspective. Interleukin (IL)-1β levels in human gingival crevicular fluid (GCF), pain intensity, and the amount of tooth movement were measured during canine retraction using different magnitudes of continuous orthodontic force. Sixteen subjects (two males and 14 females), aged 18-24 years, diagnosed with Class I bimaxillary protrusion and treated with first premolar extractions participated in this study.
