Causes of tooth fracture are the same and cause dislocation. In addition, the crown of the upper teeth can be broken when removing the lower teeth with pliers, when conducting traction of the tooth, the doctor accidentally strikes a blow with the tongs in the teeth of the upper jaw. Fracture can occur in any part of the tooth. Chance broke off part of the crown without opening the cavity of the tooth and with the discovery of her, broke off all the crowns, the fracture of the root at a different level, change crowns and roots simultaneously. Fracture of the tooth can be longitudinal, transverse, oblique. Fracture line may pass on enamel, enamel and dentin, cement and dentin. There could be other relationships. These provisions are reflected in the «Classification of acute trauma tooth» [Chupryni-on NM, 1985], from which we provide information concerning the fracture of the tooth.
