Use of an obturator with nCPAP in a premature infant with a cleft lip and palate.

Premature infants have underdeveloped lungs and their care involves the use of nasal continuous positive airway pressure (nCPAP). For an adequate amount of oxygen to enter the lungs, the palate needs to be intact. Premature infants with a cleft lip and palate remain intubated for extended periods of time with the risks inherent in long-term intubation because of the inability to maintain nCPAP.

Advanced placement, qualifying, and degree completion programs for internationally trained dentists in Canada and the United States: an overview.

Canadian and U.S. universities are faced with the challenge that they are not graduating enough dentists to meet the future needs of the Canadian and U.

Three-way trays: easy to use and abuse.

The 3-way tray technique is popular as it provides master and opposing arch impressions and an interocclusal record at the same time. Excellent clinical results can be achieved with appropriate case selection, use of rigid tray and impression materials, attention to tray positioning and other details throughout the process, and clear understanding of the limitations of the technique by the operator and dental technician.

The effect of metal ceramic restoration framework design on tooth color.

Statement Of Problem: The opacity of the metal framework in metal ceramic restorations results in reduced light transmission through the tooth that diminishes the esthetics of the tooth.

Purpose: The purpose of this study was to investigate the color change that occurs apically to a metal ceramic restoration as a result of altering the metal framework design.

Material And Methods: Color change relative to the unprepared tooth (DeltaE) between various metal ceramic restorations was determined using computer imaging and CIELAB coordinates and compared to previously determined levels of clinical acceptability.
