Clinical And Radiographic Evaluation Of Mta Pulpotomies: A Retrospective Study, Claudia Colorado 2014 Virginia Commonwealth University

Clinical And Radiographic Evaluation Of Mta Pulpotomies: A Retrospective Study, Claudia Colorado

Theses and Dissertations

Vital pulp therapy is the group of procedures indicated to maintain pulp vitality allowing for continued root development and apical closure in the presence of pulp exposure due to caries or trauma. Complete maturation results in stronger tooth structure that is more able to withstand occlusal forces. Historically, calcium hydroxide (Ca(OH)2) was the material of choice for a vital pulpotomy. Recently mineral trioxide aggregate (MTA) has been used as a pulp sealing material because of its biocompatibility and its ability to induce hard tissue barrier formation. The purpose of this retrospective study was to evaluate the clinical and ...

Development Of A Simplified Pediatric Obstructive Sleep Apnea (Osa) Screening Tool, Jo Cronly 2014 Virginia Commonwealth University

Development Of A Simplified Pediatric Obstructive Sleep Apnea (Osa) Screening Tool, Jo Cronly

Theses and Dissertations

Background: Obstructive sleep apnea has become recognized as one of the most common, under-diagnosed chronic diseases. Recently studies have shown increased numbers among the pediatric and adolescent population. OSA in children is associated with behavioral problems, poor school achievements, and in severe cases, pulmonary hypertension. OSA is often the Achilles heel of pediatric sedation and analgesic programs; during sedation, children with OSA have an increased vulnerability of their airway undergoing pharyngeal collapse and of having upper airway obstruction. Consequently, pediatric dentists who practice sedation dentistry should exercise extra precautions when treating patients with risk of sleep apnea. Currently there is ...
