Stainless steel alloys containing 8% to 12% nickel and 17% to 22% chromium are generally used in orthodontic appliances. A major concern has been the performance of alloys in the environment in which they are intended to function in the oral cavity. Biodegradation and metal release increase the risk of hypersensitivity and cytotoxicity. This case report describes for the first time a CAD/CAM zirconium bar as a bonded mandibular fixed retainer with 2-year follow-up in a patient who is subjected to long-term treatment with fixed orthodontic appliance and suspected to have metal hypersensitivity as shown by the considerable increase of nickel and chromium concentrations in a sample of patient's unstimulated saliva...

BACKGROUND: Various components of appliances used in fixed orthodontic treatment are fabricated from materials that are highly resistant in nature and have high strength and biocompatibility. Corrosion of materials occurs inside the oral cavity due to numerous environmental or oral factors that act on them. These factors include temperature, pH variation, salivary conditions, mechanical loads, microbiological and enzymatic activity, and various food components. Gingival crevicular fluid (GCF) is the material obtained from the gingival sulcus and might act as a potential source for various biomarkers in the orthodontic setup because inflammatory-induced response is directly related to orthodontic forces in GCF...

PURPOSE OF REVIEW: Sleep-disordered breathing encompasses a broad spectrum of sleep-related breathing disorders, including obstructive sleep apnea (OSA), central sleep apnea, as well as sleep-related hypoventilation and hypoxemia. Diagnostic criteria have been updated in the International Classification of Sleep Disorders, Third Edition and the American Academy of Sleep Medicine Manual for Scoring Sleep and Associated Events. Neurologic providers should have basic knowledge and skills to identify at-risk patients, as these disorders are associated with substantial morbidity, the treatment of which is largely reversible...

Nutrition is important in every stage of child development. A child born with cleft lip and palate may experience difficulties while feeding due to the lack of seal of the oral cavity due to incomplete facial and palatal structures. Difficulty in feeding leads to inadequate nutrition and affects the health. Children with cleft lip and palate need certain modifications to thrive and grow. Feeding difficulties should be assessed and intervened as early as possible, as they are an important aspect of multidisciplinary team approach in management and may have an impact on long-term outcome...

Continuous positive airway pressure (CPAP) is the primary treatment of obstructive sleep apnea/hypopnea syndrome (OSA). Most sleep physicians are in agreement that a certain number of OSA patients cannot or will not use CPAP. Although other conservative therapies, such as oral appliance, sleep hygiene, and sleep positioning, may help some of these patients, there are many who fail all conservative treatments. As sleep surgeons, we have the responsibility to screen patients for both symptoms and signs of OSA...

Oral appliances that advance the mandible are widely used as alternatives to positive airway pressure (PAP) devices or as primary therapy for obstructive sleep apnea (OSA) in adults. Although PAP is more efficacious at lowering the polysomnographic indices of OSA, the clinical effectiveness of PAP and oral appliances is similar, and patients are more likely to adhere to oral appliance therapy than to PAP treatment. Clinical examination is used to determine the candidacy of oral appliances and to select a particular appliance for a given patient...

Sleep-related breathing disorders (SRBD) consist of a variety of clinical entities, ranging from primary snoring to severe obstructive sleep apnoea at the opposite extreme. Although it has no official definition, minimally invasive surgery infers surgery where the procedure is clinically less aggressive and may involve a much smaller incision or none at all. It also implies that such procedures may result in a quicker recovery and reduced morbidity, and that they are often conducted under local anaesthesia as day cases...

Pain is an unwelcome sleep partner. Pain tends to erode sleep quality and alter the sleep restorative process in vulnerable patients. It can contribute to next-day sleepiness and fatigue, affecting cognitive function. Chronic pain and the use of opioid medications can also complicate the management of sleep disorders such as insomnia (difficulty falling and/or staying asleep) and sleep-disordered breathing (sleep apnea). Sleep problems can be related to various types of pain, including sleep headache (hypnic headache, cluster headache, migraine) and morning headache (transient tension type secondary to sleep apnea or to sleep bruxism or tooth grinding) as well as periodic limb movements (leg and arm dysesthesia with pain)...

Occlusal splints to treat bruxism are commonly made from polymethylmethacrylate (PMMA) in a manual workflow (powder-liquid technique). Today digitalization allows a machine-based manufacturing in subtractive (milling) and additive (printing) means using industrial-made PMMA or comparable resins. An in-vitro study should assess the surface finish and screen the wear resistance of conventional and industrial materials. Therefore, a total of 30 specimens made from conventionally PMMA (group C; powder-liquid, Palapress), polycarbonate ingots (group S; innoBlanc splint plus), and light-curing resin (group A; VarseoWax splint) were polished to examine the surface roughness (Ra) by profilometry and further analyzed by SEM...

Obstructive sleep apnea (OSA) is a common breathing disorder, and continuous positive airway pressure (CPAP) therapy together with its alternatives has been developed to treat this disease. This network meta-analysis (NMA) was aimed to compare the efficacy of treatments for OSA. Cochrane Library, MEDLINE, and Embase were searched for eligible studies. A conventional and NMA was carried out to compare all therapies. Sleeping characteristics, including Apnea-Hypopnea Index (AHI), Epworth Sleepiness Scale (ESS), arterial oxygen saturation, and arousal index (AI), and changes of blood pressure were selected as outcomes...

Justin C Brockbank
Obstructive sleep apnea syndrome (OSAS) is common in childhood and is characterized by recurrent upper airway obstructive events during sleep that produce significant neurocognitive and cardiovascular sequelae. The pathophysiology of childhood OSAS is complex and involves mechanical airway obstruction often secondary to adenotonsillar hypertrophy. However, neuromotor abnormalities and instability of central ventilatory control are also implicated. Several surgical and non-surgical treatment options for childhood OSAS are available, and will be discussed...

BACKGROUND: Obstructive sleep apnea (OSA) manifests as a reduction or complete cessation of airflow despite an ongoing inspiratory effort, leading to hypoxemia and hypercapnia. The inability to maintain normal breathing reduces the oxygen saturation in blood leading to a cycle of various systemic implications. Hence, a prospective single arm study was planned to evaluate the long-term (2 years) effect of oral appliance on cardiovascular fitness and psychomotor performance in patients with mild to moderate obstructive sleep apnea...
