Despite the recent recommendation by the American Association of Orthodontists and Dentofacial Orthopedics that orthodontists begin screening patients by age 7, it is the author's experience that the majority of orthodontists do not treat children prior to the eruption of permanent teeth and do not use functional appliances. This leads many general dentists to provide orthodontic services to th...

Halitosis is a widely spread condition. There are numerous causes. The aim of this study was to investigate the influence of fixed orthodontic appliances on the occurrence of halitosis. 55 patients in an orthodontic practice were monitored at three points in time after application of orthodontic appliance (T1: immediately after application, T2: 4 weeks after application, T3: 3 months after appl...

AIM The knowledge of the distribution and causes of malocclusion in early childhood can prevent such malocclusions and their consequences and possibly to reduce complex orthodontic treatment. METHODS All children (n = 234; 116 male, 118 female, age 2-16) who presented with occlusal or functional problems at the Department of Paediatric Dentistry at Damascus University (1995-1999) were classif...

background: orthodontic therapy has oral ecological changes causing increased numbers of mutans streptococci in saliva and plaque. the purpose of this study was to estimate counts and colonization pattern of streptococcus mutans after application of fixed orthodontic appliances. materials and methods: plaque samples of randomly selected sixty patients were collected before placement of orthodon...

OBJECTIVE The aim of this prospective study was to compare the periodontal health and the microbiological changes via real-time polymerase chain reaction (PCR) in patients treated with fixed orthodontic appliances and Invisalign(®) system (Align Technology, Santa Clara, California). MATERIALS AND METHODS Seventy-seven patients were enrolled in this study and divided into three groups (Invisal...

Orthodontic appliances are usually made of stainless steel, which contains metals such as nickel, chromium and iron that have been associated with DNA damage. The aim of the present study was to determine the genetic toxicity associated with orthodontic fixed appliances in twenty healthy patients (16 +/- 2.5 years) undergoing orthodontic treatment (fixed appliances - basic composition: stainles...

Purpose: The aim of the study was to determine whether fixed orthodontic appliances cause root and alveolar bone resorption and to compare the precision of orthopantomography and computerized tomography in detection of resorption process. Methods: Eighty-five patients scheduled for orthodontic therapy with fixed appliances were included in prospective self-controlled study. Before and after ort...

INTRODUCTION The first straight-wire appliance was introduced over 40 years ago to increase the consistency and efficiency of orthodontic treatment. More recently, computer-aided design and computer-aided manufacturing (CAD/CAM) technology has been used to create individualized orthodontic appliances. The purpose of this study was to investigate the clinical effectiveness and efficiency of CAD/...

A new modality of orthodontic treatment based on the thermoformed appliance was developed and trialled clinically. A light-cured resilient lining material commonly used for denture relining was placed locally and sequentially in thermoformed appliances to generate orthodontic forces. The new method appeared to be effective. All the presented cases showed substantial improvement in dental alignm...

INTRODUCTION The effects of orthodontic treatment are considered to be successful if the facial harmony is achieved, while the structures of soft tissue profile are in harmony with skeletal structures of neurocranium and viscerocranium. In patients with skeletal distal bite caused by mandibular retrognathism, facial esthetics is disturbed often, in terms of pronounced convexity of the profile a...
