TEETH EXTRACTION WITH ROOT DELACERATION ON THE ORTHODONTIC INDICATIONS

Dilaceration of root is a phenomenon that changes the axial axis of the tooth at an angle, at the crown or root’s level. The actual mechanical obstructions in the way of dental eruption can be: root canal infections in the neighborhood tissues, development of the ectopically located dental germs and lack of space for them, anatomically dense structures, ankylosis temporary tooth, and so on. The purpose of our study is to analyze the causes of dental root dilaceration in patients, the first with the upper central incisor affected, and the second with the lower first premolar affected, as well as the approaches to their orthodontic treatment. In the first clinical case, the root dilaceration of the lower right first premolar is due to the development of a large cystic formation from a devialized lower right first temporary molar. In the second clinical case a rectangular upper left central incisor with a delacerated apex and a reversed direction of a crown-root was found, with the crown near the nasal cavity. The most accurate morphology of the affected teeth may be performed by a CBCT study. The treatment approach in both patients is extraction of the tooth with root dilaceration. In the first clinical case, the mechanical force that compresses and changes the direction of tooth formation is the cystic collection. In the second clinical case, the real cause of the delaceration and inverted direction of the germ of an upper left central incisor is not clear. A trauma of temporary teeth is often overlooked by parents. An early and timely intervention can save patients from the consequences of this trauma. Clinicians, who treat such as cases should use pre-diagnostic means such as CBCT to plan the treatment. Parents and dentists should devote particular attention to the deviated temporary teeth which shift is delayed. It is necessary to carry check-ups out at the age of tooth replacement, obligatory with X-ray followed by the consultation with an orthodontist.
