Abstract

Obstructive sleep apnea (OSA) is recognized as an important health issue in the last two to three decades. It is characterized by frequent episodes of upper airway collapse during sleep, causing recurrent arousals, intermittent hypoxaemia, sleep fragmentation and poor sleep quality. Obstructive sleep apnea (OSA) is a prevalent disorder with significant co-morbidities. There are evidences that OSA is being considered as an independent risk factor for hypertension, glucose intolerance/diabetes mellitus, cardiovascular diseases and stroke, leading to increased cardiometabolic morbidity and mortality. Early recognition and treatment of obstructive sleep apnea may prevent adverse health consequences. In this sense, treating the patient with obstructive sleep apnea requires a long-term partnership between patient and healthcare providers. With a strong partnership, obstructive sleep apnea may be effectively treated in the growing numbers of patients. In this article some of the epidemiological aspects, consequences, medical and dental treatment options of obstructive sleep apnea are reviewed.

Abstract

An altered facial appearance is more difficult to face, than problems related to ill-fitting denture or eating. The selection of maxillary anterior teeth for complete denture has long posed problem in clinical practice and a controversy about the best method to employ still exists. An attempt is made in the present study to clinically correlate the face form with maxillary central incisor tooth form in males and females of Davangere population. In 1914, Leon William's projected the "the form method" where he classified facial forms as square, tapering, and ovoid. Maxillary central incisors were selected according to the facial forms.
Of total 100 subjects four different tooth forms and face forms were evaluated. They are: square, ovoid, square-tapered, tapered. No significant correlation existed between face form in male and females. Females exhibited greater correlation between face forms and inverted tooth form but that correlation is not sufficient to serve as a guide for selection of anterior teeth.

Keywords

Abstract

When all the remaining natural teeth are removed, there exists a space within the oral cavity that can be called the potential denture space. Within this denture space there is an area that has been termed the neutral zone. Neutral zone is defined as that area or position within the oral cavity where the forces between the tongue and cheeks or lips are equal. Thus making it the zone of minimal conflict, where the function of musculature will not unseat the denture and help in stabilizing the denture. In the present case the neutral zone was recorded using admix technique and impression compound as the material of choice.

Keywords
