Using a Dental Operating Microscope in the Treatment of Reversible Pulpitis in Primary Teeth

Objectives: Treatment with minimal intervention is a new philosophy in modern dentistry. High-tech diagnostic tools and methods are used in the practice to ensure early disease detection and treatment with minimal loss of damaged structures. The aim of this study is t o investigate the application of the magnifying method with a digital operating microscope (DOM) in combination with controlled excavation with fluorescent method (Proface) in the treatment of asymptomatic closed pulpitis in primary molars, treated through an indirect pulp capping. Materials and Methods: Subject of the study were 40 primary molars (19 first and 21 second molars) of children (20 girls and 20 boys) at the ages of 4-7, with cavitated carious lesions in the dentine, suspected for an asymptomatic closed pulpitis. All cases were excavated with an identical clinical protocol (conventional excavation). The excavation was controlled through the  fluorescent method (Proface) . An assessment of the residual dentine, with and without microscope  ( DOM )  at three levels of magnification, was made at each stage.  Results: The use of DOM shows a: larger diversity in the colors and nuances of the carious dentine, with lighter shades being predominant. DOM gives an opportunity for a better precision in determining the speed of the carious process, which is in direct relation to the defensive ability of the pulp-dentine complex. In the biological treatment of asymptomatic closed pulpitis in primary teeth, the use of DOM magnifying technology gives the opportunity for a precise and accurate assessment during the course of excavation. Conclusion: T he use of magnifying technology complements the objective assessment in the area of the overpulpal dentine, which in reversible pulpitis of primary teeth, must be preserved and used for the stimulation of the healing process.
