Obstructive sleep apnoea (OSA) is characterised by pharyngeal obstruction occurring at different sites. Endoscopic studies reveal that epiglottic collapse renders patients at higher risk of failed oral appliance therapy or accentuated collapse on continuous positive airway pressure. Diagnosing epiglottic collapse currently requires invasive studies (imaging and endoscopy). As an alternative, we propose that epiglottic collapse can be detected from the distinct airflow patterns it produces during sleep.23 OSA patients underwent natural sleep endoscopy...

Dental hygienists are often faced with patients wearing lingual orthodontic therapy, as ultrasonic instrumentation (UI) is crucial for oral health. As the application of external forces can lead to premature bonding failure, the aim of this study was to evaluate the effect of UI on shear bond strength (SBS) and on adhesive remnant index (ARI) of different lingual orthodontic brackets. 200 bovine incisors were divided into 10 groups. Four different lingual (STB, Ormco; TTR, Rocky Mountain Orthodontics; Idea, Leone; 2D, Forestadent) and vestibular control (Victory, 3M) brackets were bonded...

Patients may face functional, aesthetic, and social distress because of the palatal defects. Prosthetic rehabilitation of maxillectomy or developmental defect can be challenging for prosthodontists. Prognosis of the prosthetic appliances can be affected not only by patients' own ability to adapt to the prosthesis but also by the factors like the remaining teeth, bony structure, and existing mucosa. Maxillary defects are usually developed by surgical intercession of the benign or malignant conditions and trauma cases...

REVIEW
Geraldo Lorenzi-Filho, Fernanda R Almeida, Patrick J Strollo
Continuous positive airway pressure (CPAP) is the standard treatment for moderate-to-severe obstructive sleep apnoea (OSA). However, adherence to CPAP is limited and non-CPAP therapies are frequently explored. Oral appliance (OA) therapy is currently widely used for the treatment of snoring, mild, moderate and severe OSA. The most commonly used and studied OA consists of a maxillary and mandibular splint which hold the lower jaw forward during sleep. The efficacy of OA is inferior to CPAP; however, the effectiveness as measured by sleepiness, quality of life, endothelial function and blood pressure is similar likely due to higher acceptance and subjective adherence...

REVIEW
Laurynas Jokubauskas, Aušra Baltrušaitytė, Gaivilė Pileičikienė
The review focuses on the last decade of research regarding the use of various oral appliances (OA) in the management of sleep bruxism (SB) in adults. Sixteen (N = 16) papers out of 641 identified citations involving 398 participants were included in the review. Of them, 7 were randomised controlled trials (RCTs), 7 were uncontrolled before-after studies and 2 were crossover trials. Analysis of the included articles revealed a high variability of study designs and findings. Generally, the risk of bias was low-to-unclear for RCTs and high for crossover studies, whilst the before-after studies exhibited several structural limitations...

The purpose of this study was to determine the effectiveness of toothpaste Parodontax in patients undergoing orthodontic treatment. The results showed that fixed orthodontic appliances deteriorated oral hygiene, increased the viscosity of saliva and reduced mineralizing capacity of saliva (MCS). Use of Parodontax toothpaste based on sodium bicarbonate improved OHI-S, reduced the viscosity of saliva, increased MCS and normalized oral microbiota.

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 cellular death due to apoptosis. MATERIALS & METHODS: Orthodontic appliances such as brackets, wires, resins and soldering have some components that can be considered as potential allergen, carcinogenic, cytotoxic and gene mutation factors...

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...
