INTRODUCTION Orthodontic tooth movement is fraught with risks and complications. Root resorption is the most frequent and important outcome which may arise due to inappropriate force magnitude or tooth movement into dense or altered bone. This study was aimed to demonstrate histologic changes in tooth roots following movement into a jaw region treated with synthetic bone substitute. Another obj...

Aim: The aim of the present study was to evaluate the skeletal and dento-alveolar effects of the Rick-A-Nator appliance in the treatment of growing patients with skeletal Class II malocclusion due to retrusive mandible. Methods: 13 Class II growing patients with mandibular retrusion and between the ages of 9 years and 12 years were selected to be included in this study. Control group for the tr...

AIM Assess the effectiveness of chemical-mechanical control associated with orientation and motivation for the control of dental biofilm in orthodontic patients. METHODS AND MATERIALS Thirty patients between 12 and 21 years of age wearing a fixed orthodontic appliance were divided into three groups. The control group (G1) received orientation regarding oral hygiene. The experimental groups (G...

This controlled longitudinal intervention study investigated changes in cytokines and biomarkers of bone and tissue metabolism within gingival crevicular fluid (GCF) from patients undergoing orthodontic treatment. GCF was collected on Periopaper™ strips (Oraflow Inc., USA) from 20 volunteers at baseline, before tooth extraction and appliance placement and then at intervals during orthodontic tr...

OBJECTIVE Oxidative stress is a pathologic event induced by a prevalence of oxidant agents on the antioxidant ones, with a consequent alteration of oxide-reducing balance. INTRODUCTION Freeradicals produce damages both in cellular and extra-cellular components; phospholipid membranes, proteins, mitochondrial and nuclear DNA, are the target of the oxidative stress, that can finally cause cellu...

The study maps out orthodontic care in Finnish municipal health centres in 2001, describes changes during the previous ten years reported by chief dental officers, and assesses the views of orthodontists on current public orthodontic services. The data were collected by questionnaires sent to all health centres and all orthodontists in Finland. Of all 0-18-year-olds, 11% were receiving orthodon...

Fixed appliance treatment is a popular treatment modality with a burgeoning increase in the numbers of children and adults realizing the benefits that can be gained. Appliance breakage is an unavoidable nuisance which is at best inconvenient, and at worst may result in significant pain or discomfort for the patient. General dental practitioners (GDPs) should have the practical knowledge of how ...

This randomized split-mouth study aimed to examine the levels of matrix metalloproteinases (MMPs) -1, -2, -3, -7, -8, -12, and -13 in the gingival crevicular fluid (GCF) at different time points during orthodontic tooth movement. A total of 16 healthy orthodontic subjects (7 females, 9 males; mean age, 17.7 years) who needed their first upper premolars extracted were enrolled. One randomly chos...
