Q

Which type of study is being described?

17 GDPs recruited 132 children (3-10) with caries affecting matched pairs of asymptomatic primary molar teeth. One tooth was allocated to restoration with the intervention, the Hall Technique and the contralateral tooth was treated using the restorative technique the GDP would usually choose for that case.

Q

Which type of study is being described?

Lacrimal acinar cells were isolated by collagnase digestion from adult male outbred Swiss mice killed by cervical dislocation. Cells were allowed to attach to a plastic petri dish and the whole cell patch clamp configuration was achieved with single cells. Cells were voltage-clamped using the list EPC7 patch-clamp amplifier and K+ and Cl- currents were measured using a pulse protocol.

Q

Which type of study is being described?

MEDLINE, CINAHL, the Social Sciences Citation Index and Health Service Abstracts were searched using the keywords ‘dental health education’, ‘oral health promotion’, ‘effectiveness’ and ‘evaluation’. Studies reporting any oral health promotion intervention were eligible for inclusion provided that they reported an evaluative component.

Q

Which type of study is being described?

Patients with a putative diagnosis of infective endocarditis ere identified by hospital personnel and reported to study nurses, who also actively sought cases. One (age and sex matched) control from the community was selected for each case-patient by using a modification of the Waksberg random-digit dialling method.
