Impact of soft palate visibility and tongue position on early diagnosis of obstructive sleep apnea among patients with tooth loss - An observational preliminary study.

Background: Obstructive sleep apnea (OSA) was estimated to affect 15% to 30% of males and 5% to 15% of females with prevalence increasing with progressive tooth loss and its early identification can reduce the sequalae of OSA. Apnea-hypopnea index is confirmatory but unsuitable for clinical settings to detect OSA and concise screening tools are required to detect OSA in edentulous patients.

Aim: To evaluate the impact of soft palate visibility and tongue position on incidence of OSA among edentulous patients.

GC-MS and Surface Characteristics of Polyvinyl Siloxane-An In Vitro Analysis.

Objective: To assess the surface characteristics, composition and release of components of Polyvinyl siloxane (PVS) impression material and explore the use of the material other than for impressions.

Methods: Forty samples of 0.5-mm thickness and 8-mm diameter PVS discs, with few perforations, were prepared and divided into four groups.

Flipped clinical training: a structured training method for undergraduates in complete denture prosthesis.

Purpose: To design and implement flipped clinical training for undergraduate dental students in removable complete denture treatment and predict its effectiveness by comparing the assessment results of students trained by flipped and traditional methods.

Methods: Flipped training was designed by shifting the learning from clinics to learning center (phase I) and by preserving the practice in clinics (phase II). In phase I, student-faculty interactive session was arranged to recap prior knowledge.

Fabrication of temporary speech bulb prosthesis: A clinical report.

Maxillofacial prosthesis is an art and science which not only replaces the lost structure sometimes it restores the functions also. Pharyngeal obturator is a prosthesis which closes the palatal and pharyngeal defects and improving the speech and other function. The following case report discusses palatopharyngeal insufficiency, impression procedures, fabrication of prosthesis and improvements in speech.
