Background/aim: Obstructive sleep apnea (OSA) is one of the most prevalent sleep disorders. It is recognized as a serious risk factor for car and workplace accidents due to daytime sleepiness, and factor for coronary heart diseases and stroke. The aim of this study was to examine the effectiveness of oral appliances for mandibular advance in treating mild to moderate OSA.
Methods: A total of 15 patients were included in this study, all diagnosed with mild or moderate OSA. Oral appliances were custom made for each patient in protrusive position at 50% of maximum mandibular advancement. The patients were given instructions not to sleep on their backs and avoid alcohol consumption during the study as these are the factors that can contribute to symptoms progression.
Results: Complete and partial treatment success was achieve in 14 of the patients. Apnea-hypopnea index values were significantly lower (p < 0.05) at the end of a 6-month observation period compared to those at the treatment beginning. A great improvement in symptoms was observed, with daytime sleepiness index values significantly reduced already within the first month of the treatment.
Conclusion: Treatment of obstructive sleep apnea with oral appliances has proven successful. Patients were comfortable using oral appliances and were ready to wear them for prolonged period of time. Use of oral appliances is very common in the world and should not be discarded. They are also very comfortable, practical and affordable comparing to continuous positive airway pressure (CPAP) apparatus, not to mention surgery. Use of oral appliances is safe and very well tolerated, and ought to be offered to patients with OSA.

Background: Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non-carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics. There is limited evidence regarding tunnel-based procedures combined with connective tissue grafts (CTGs) for treating recession-associated NCCLs.

A total of 40 otherwise healthy patients with generalized periodontitis, encompassing 1,168 sites with deep pockets, were included and baseline PPD, bleeding on probing (BOP), gingival recession (REC), clinical attachment level (CAL), and plaque index (PI) were recorded. Each patient underwent non-surgical laser-assisted periodontal therapy and was enrolled in a maintenance program with three-month recall visits during the first year of follow-up.

Introduction: Obstructive sleep apnoea (OSA) is characterised by blood oxygen desaturations and sleep disruptions manifesting undesirable consequences. Existing treatments including oral appliances, positive airway pressure (PAP) therapy and surgically altering the anatomy of the pharynx have drawbacks including poor long-term adherence or often involving irreversible, invasive procedures. Bilateral hypoglossal nerve stimulation (HNS) is a new treatment for managing OSA, and this study is intended to determine whether an HNS system is a safe and effective treatment option for adults with OSA.

Objectives: The presented study aimed to evaluate the effect of mandibular protrusion with a temporarily applied mandibular advancement device (MAD) on the posterior airway space and to determine a reliable metric constant based on a three-dimensional computed tomography (CT) evaluation.
Materials And Methods: The study population consisted of patients with oral squamous cell carcinoma who were treated at least six months prior to the follow-up CT in supine position. Each patient received an individually adjusted MAD that was temporarily applied with three different protrusion distances (P = 0 mm, P = 4 mm, and P = 8 mm) during follow-up CT.
