Transformation of dental services from a governmental model to a revenue-generation model of operation in a tertiary care hospital: a health economics assessment.

Background: Healthcare in Saudi Arabia is under transformation from a national free health service to a system paid either by insurance or governmental funds. This change will impact the model of operation including dental services.

Objectives: Estimate the revenue of the Department of Dentistry based on an insurance-based billing system.

Biomimetic approach to perforation repair using dental pulp stem cells and dentin matrix protein 1.

Introduction: Dentin regeneration could be an ideal treatment option to restore tissue function. This study was conducted to evaluate the ability of dental pulp stem cells (DPSCs) and dentin matrix protein 1 (DMP1) impregnated within a collagen scaffold to regenerate dentin.

Methods: Simulated perforations were created in 18 dentin wafers made from freshly extracted human molars.

In vivo generation of dental pulp-like tissue by using dental pulp stem cells, a collagen scaffold, and dentin matrix protein 1 after subcutaneous transplantation in mice.

The presence of a perforation is known to significantly compromise the outcome of endodontic treatment. One potential use of regenerative endodontic therapy might be the repair of root canal perforations. In addition to nutrients and systemic in situ interactions, the 3 main components believed to be essential for tissue regeneration are stem cells, scaffold, and growth factors.
