Ensuring data quality in medical research through an integrated data management system.

An effective data management system ensures high quality research data by making certain of the proper execution of the study design. This paper presents the components of a data management system and describes procedures for use in each component of the system to obtain high quality data. We discuss the interrelationship among the components of the data management system and the relationship of the data management system to other parts of the research project. We identify underlying principles in design and implementation of a data management system to ensure high quality data.

Evaluation of mandibular infiltration versus block anesthesia in pediatric dentistry.

The authors consider mandibular infiltration as a possible alternative to mandibular block anesthesia in young children. The study sample comprised eighteen children ages six to nine years old who required bilateral identical treatment on primary mandibular molars. A random number table was used to determine which side of the mouth was to receive the block or the infiltration technique and a coin toss determined which would be administered first: A short 27 gauge needle was used to inject a 2 percent lidocaine solution with 1:100,000 epinephrine, in both techniques. The paired t-test indicated no significant difference between the two techniques for any of the factors evaluated.
