NCT05427773
The primary objective is to assess the relation between involuntary and voluntary assessed quadriceps muscle endurance in patients with COPD. We hypothesized a good correlation (\>0.8) between the measurements.
NCT05124418
Periodontal plastic surgery is widely used to improve the esthetic and functional demands of patients. The palatal masticatory mucosa is the main donor area. A lot of methods to evaluate the thickness of palatal soft tissue were used. However, the methods published before were invasive or non-reproducible. Therefore, the aim of this study was to investigate the accuracy of the novel invasive method to evaluate the thickness of palatal masticatory mucosa thickness. Twelve periodontally healthy patients who will have CBCT on maxilla for implant surgery will be recruited in this study. Each patient will be measured at 15 points of palatal masticatory mucosa over canine to the second molar area, it will be done by a dynamic navigation system (test group) and periodontal probe piercing (control group). The data will be analyzed to evaluate the accuracy of dynamic navigation in the measurement of palatal masticatory mucosa thickness.

This project evaluates the morphological predictive factors for prescribing a mandibular advancement device in the therapeutic approach of Obstructive sleep apnea (OSA). The investigators will carry out the project with patients who travel to CUF Tejo Hospital to solve their sleep disturbance, namely cases of obstructive sleep apnea. The investigators designed three groups of 22 individuals each. The investigators will only include individuals after signing the informed consent. In the 1st appointment, the principal investigator will conduct a complete anamnesis and a clinical examination, where several items will be documented: Age, gender, body mass index, mallampati index, neck, and waist circumference. The clinical interview will assess the patient's daytime sleepiness, nighttime snoring, and quality of life through the respective questionnaires: the Epworth Sleepiness Scale (ESS), the snoring severity scale (SSS), and the Sleep Apnea Quality of Life Index (SAQLI). Still, in the 1st consultation, a level III Polysomnography (PSG) will be prescribed to assess the possibility of OSA, and a pharyngeal computed tomography (CT) with cephalometric analysis and recording in maximum comfortable protrusion to evaluate the Upper Airway (UA) and the prognosis of mandibular advancement in case of UA collapse. The other group will perform Drug-Induced Sleep Endoscopy (DISE) and CT with registration in maximum comfortable protrusion. Then, the investigators will make personalized and titled mandibular advancement devices (MAD). The measurements and PSG III questionnaires will be carried out after 1 and 6 months to evaluate the results.
