Klaus Bsl Batista, Badri Thiruvenkatachari, Jayne E Harrison, Kevin D O'Brien
BACKGROUND: Prominent upper front teeth are a common problem affecting about a quarter of 12-year-old children in the UK. The condition develops when permanent teeth erupt. These teeth are more likely to be injured and their appearance can cause significant distress. Children are often referred to an orthodontist for treatment with dental braces to reduce the prominence of their teeth. If a child is referred at a young age, the orthodontist is faced with the dilemma of whether to treat the patient early or to wait and provide treatment in adolescence...

PURPOSE: In 2005, the American Academy of Sleep Medicine stated, "Oral appliances are indicated for use in patients with mild to moderate obstructive sleep apnea (OSA) who prefer them to CPAP therapy, or who do not respond to, are not appropriate candidates for, or who fail treatment attempts with CPAP." However, this recommendation is based upon variable results from only six studies with more than 100 participants. These studies have assessed the effectiveness of mandibular advancement devices (MADs) in specific groups (military populations, academic institutions, or hospital settings) with no large study conducted in a fee-for-service private practice where the majority of patients receive MADs for OSA...

Chronic recurrent temporomandibular joint (TMJ) dislocation is both an uncommon and debilitating condition of the facial skeleton. Various conservative management strategies have been tried, but these have often been associated with poor and transient outcomes. The use of a simple, innovative, and non-invasive solution is presented herein. A co-ordinated multidisciplinary approach was used in which the oral and maxillofacial laboratory technicians produced a customized headgear appliance that utilizes a 'seat belt'-like technology...

Haematemesis is a worrying sign, generally related to acute upper gastrointestinal bleeding and potentially life-threatening condition. We present a case of a 15-year-old Caucasian girl who was belatedly diagnosed with oral bleeding because it was not related to the most common aetiologic factors. In fact, she was undergoing orthodontic treatment with a Nance palatal arch, an appliance used to reinforce anchorage during teeth movements. In her case haematemesis was a sign of inflammation and necrosis occurring in the palatal mucosa, under the acrylic button of palatal arch...

OBJECTIVE: Our objective was to determine primary open-angle glaucoma (POAG) prevalence among obstructive sleep apnea (OSA) patients because the perioperative environment risks further damaging the optic nerve. STUDY DESIGN: We analyzed a "convenience sample" referred by Sleep Medicine for oral appliances because of continuous positive airway pressure intolerance. We determined the aggregate prevalence of the 3 POAG subtypes-"classic" open-angle glaucoma (COAG), normal-tension glaucoma (NTG), and open-angle glaucoma suspect (OAGS)-among the index population and compared it with that of same hospital's general population...

Iatrogenic trauma though not serious is very common in dental practice. Orthodontic treatment can inflict such injuries as they are prolonged over a long period of time. Ill-fabricated orthodontic appliances, such as wires and brackets, or the patients' habits such as application of constant pressure over the appliance can traumatize the adjacent oral soft tissues. In rare cases, these appliances can get embedded into the mucosa and gingival tissues. This case report describes one such case of iatrogenic trauma to the palatal mucosa due to entrapment of a tongue spike appliance and its surgical management...

PURPOSE: Oral appliance therapy is an alternative treatment modality for obstructive sleep apnea (OSA). However, there have been no studies to determine whether changes in the obstructive pattern occur following long-term use of oral devices. Therefore, we examined whether the obstructive pattern changes in patients with OSA who undergo long-term oral appliance therapy using drug-induced sleep endoscopy (DISE). METHODS: We investigated 156 consecutive patients diagnosed with OSA...

BACKGROUND: Magnetic resonance imaging (MRI) has been used to study configurations of speech organs in the resting state. However, MRI is sensitive to metals, and numerous types of metallic appliances, most of which have a large magnetic susceptibility, are used in orthodontic treatment and may cause severe artifacts on MRI. We have developed techniques for obtaining MRI movies of the oral region, to evaluate articulatory changes, especially movement of the tongue, palate, and teeth, pre- and post-orthodontic/orthognathic treatment...

Background A sleep study of a 56-year old male with excessive daytime sleepiness demonstrated an AHI of 16.4hr -1 with 13% of total sleep time in REM sleep and a mean oxygen desaturation (SpO 2 ) of 86%. Clinical presentation On intra-oral examination, it was found that the patient had maxillary hypoplasia and bilateral torus mandibularis. A 3D cone-beam CT (CBCT) scan was taken, and 28 craniofacial parameters were measured. Surgical reduction of the mandibular tori followed by biomimetic oral appliance therapy (BOAT) was initiated...

Continuous positive airway pressure (CPAP) remains the gold standard treatment for obstructive sleep apnoea hypopnoea syndrome (OSAHS). However, the high efficacy of CPAP is offset by intolerance and poor compliance, which can undermine effectiveness. This means that alternatives to CPAP are also necessary. In recent years, oral appliances have emerged as the leading alternative to CPAP. There is now a strong body of evidence supporting their use in OSAHS and clinical guidelines now recommend their use in mild OSAHS and in more severe cases when CPAP fails...

BACKGROUND: Adolescents with fixed orthodontic appliances are at high risk of developing dental caries. To date, new smartphone technologies have seldom been used to support them in the preventive behavior that can help prevent dental caries. After an intervention-mapping process, we developed a smartphone application (the WhiteTeeth app) for preventing dental caries through improved oral-health behavior and oral hygiene. The app, which is intended to be used at home, will help adolescents with fixed orthodontic appliances perform their oral self-care behavior...

INTRODUCTION: Clear aligners and to a lesser extent self-ligated brackets are considered to facilitate better oral hygiene than traditional fixed orthodontic appliances. This 3-arm parallel-group prospective randomized clinical trial compared the long-term and short-term effects of clear aligners, self-ligated brackets, and conventional (elastomeric-ligated) brackets on patients' oral hygiene during active orthodontic treatment. METHODS: Seventy-one participants (41 boys, 30 girls; mean age, 15...

BACKGROUND: Corrosion resistance is an important requirement for orthodontic appliances. Nickel and chromium may be released from orthodontic wires and can cause allergic reactions and cytotoxicity when patients use various mouthwashes to whiten their teeth. Our study aimed to assess the release of nickel and chromium ions from nickel titanium (NiTi) and stainless steel (SS) orthodontic wires following the use of four common mouthwashes available on the market. METHODS: This in vitro, experimental study was conducted on 120 orthodontic appliances for one maxillary quadrant including five brackets, one band and half of the required length of SS, and NiTi wires...
