Abstract

Objectives: The known fear of pain during mechanical removal of
dental caries by conventional rotating instruments has lead to the development of a novel, chemomechanical method, based on carious tissue softening by the use o f a special solution. The main constituent of the solution is aminobutyric acid, which dissolves carious tissue by decomposition o f its collagenous structure. Material and Methods: The procedure consists of directing pulsating jets of warmed solution at the carious lesion using an electronic device. The layers of carious tissue are softened by the solution, and the use of an electronic device allows selectivity and evacuation of carious tissue from a particular tooth. The solution has no effect on healthy dentin, tooth pulp or surrounding soft tissue, and causes no allergic reactions.
Results: The study was performed in a sample of 60 patients. After
the use o f the solution, carious lesions were removed in all study subjects, either by excavation or by very light grating without pressure. Study results showed that 77% of the patients felt no pain or any strange taste of the solution, and 87% of the patients required no anesthesia during caries preparation.Conclusion: Carious tissue was successfully evacuated in 75%- -100% o f the study patients. Dentin areas remained clean and uneven, with wide dentin channels providing ideal retention for composite materials. This procedure for caries removal is recommended in the case o f large carious lesions in soft and moderately hard dentin, in the preparation of class V, and in work with frightened patients, small children or patients allergic to anesthetics.
