Hall versus conventional stainless steel crown techniques: in vitro investigation of marginal fit and microleakage using three different luting agents.

Purpose: This study's purpose was to investigate microleakage and marginal discrepancies in stainless steel crowns (SSCs) placed using conventional and Hall techniques and cemented with three different luting agents.

Methods: Seventy-eight human primary maxillary second molars were randomly assigned to two groups (N=39), and SSCs were applied either with the Hall or conventional technique. These two groups were further subgrouped according to the material used for crown cementation (N=13 per group).

Oral findings and clinical implications of patients with congenital neutropenia: a literature review.

Neutropenia is a granulocyte disorder characterized by a dramatically low number of neutrophils, the most important type of white blood cell. The condition results in susceptibility to severe pyogenic infections. Some people are born with it (congenital neutropenia), and others develop it as young children.
