Developing and employing a 'responsive manualization' in the 'Acupuncture Approaches to Decrease Disparities in Outcomes of Pain Treatment' comparative effectiveness study.

Objective: The aim of this article is to describe the process used to develop an acupuncture therapy manual for a large effectiveness trial comparing individual care against group care for chronic pain in an underserved population. The design needed to not only ensure research consistency and replicability but also be 'responsive' to real world heterogeneous and evolving presentations in challenging physical settings.

Background: Chronic pain is prevalent in the United States.

An in vitro evaluation of a prototype Delrin carrier for the Thermafil obturation system.

Objective: To produce and test a prototype carrier for the Thermafil obturation system.

Method And Materials: A prototype carrier was created in a new plastic material (Delrin) with a new profile design made up of 15 intersecting cones of decreasing diameter and a 0.06 taper.

Crown fractures: effectiveness of current enamel-dentin adhesives in reattachment of fractured fragments.

Objective: The introduction of the current enamel-dentin adhesives has simplified the reattachment of fractured dentinal fragments. The objective of this study was to determine the strength needed to detach coronal fragments reattached with the most recent adhesives.

Method And Materials: A complete coronal fracture was caused on the incisal one third of 40 noncarious maxillary and mandibular lateral and central incisors.

DEHP-induced alterations in the lining tissue of the rat air pouch.

The direct effects of D(2-ethylhexyl)phthalate (DEHP), on subcutaneous tissue were studied in the rat, using the air pouch technique. Two ml of DEHP either undiluted or diluted in olive oil (10 microm/ml), were introduced into a previously created air pouch in the rats. The air pouch was removed and specimens of the lining tissue examined by optical and electron microscopy.

Effectiveness of the current enamel-dentinal adhesives: a new methodology for its evaluation.

Two Class II boxes of standardized dimensions were prepared in each of 10 extracted third molar teeth. The dentinal adhesives Syntac, Gluma 2000, Scotchbond MP, and All-bond 2 were applied to five boxes each. All the boxes were restored with the same photopolymerizing resin composite.
