Rehabilitation of a Unilateral Cleft Palate with Endosseous Implants in an Edentulous Elderly Patient.

The objective was to describe the use of a maxillary obturator supported by dental implants and ball abutments in an adult edentulous unilateral cleft patient. Adult edentulous cleft patients who have had no corrective surgeries or failed attempts at cleft repair in childhood suffer from oronasal communication resulting in hypernasal speech, dysphagia, and compromised masticatory ability. Tissue-supported obturator prostheses in such patients provide for compromised function due to instability and lack of retention.

Comparative evaluation of apically extruded debris during root canal preparation using ProTaper™, Hyflex™ and Waveone™ rotary systems.

Background And Aims: Extrusion of any debris during endodontic treatment may potentially cause post-operative complications such as flare-ups. The purpose of this in vitro study was to assess the amount of apically extruded debris during the root canal preparation using rotary and reciprocating nickel-titanium instrumentation systems.

Materials And Methods: In this study, 60 human mandibular first premolars were randomly assigned to 3 groups (n = 20 teeth/group).
