A Comparison of Primary Maxillary Incisor Zirconia and Composite Resin Strip Crowns: A One-year Feasibility Study.

Purpose: The purpose of this study was to compare one-year clinical outcomes of primary incisor strip crowns (SCs) and zirconia crowns (ZCs) and determine the frequency of pulp therapy associated with each technique.

Methods: Children aged 18 to 48 months were randomly assigned to a ZC group or SC group. Each incisor was rated as intact (I), damaged (D), or requiring treatment (TR) six and 12 months following placement.

Occurrence of paresthesia after dental local anesthetic administration in the United States.

Background: Several studies have suggested that the likelihood of paresthesia may depend on the local anesthetic used. The purpose of this study was to determine if the type of local anesthetic administered had any effect on reports of paresthesia in dentistry in the United States.

Methods: The authors obtained reports of paresthesia involving dental local anesthetics during the period from November 1997 through August 2008 from the U.
