A 8,5-year-old child is practically in good health. There is a complaint of pain in the upper left tooth, due to it having been physically damaged 3 hours ago. Objectively: 1/2 of the 21st tooth crown is destroyed, the pulp is significantly exposed, red, sharply painful and bleeding when probed. Percussion of the 21st tooth is sharply painful. Choose the optimal method of the 21st tooth treatment.

Answer options

1. Vital amputation
2. Biological method
3. Non-vital extirpation
4. Non-vital amputation
5. Vital extirpation

Explanation

First of all pay attention to clinical manifestations of tasks and indications for each treatment approach. The choice of the method of treatment depends on the time, passed since the moment of trauma, (physically damaged 3 hours ago), root development stage, (8,5-year-old child tooth 21 – stage of root formation) the size of exposed pulp, (the pulp is significantly exposed)somatic health of the child (child is mostly healthy). Pulp viability preservation is extremely important for immature teeth. (Devital methods are not good) In case of dotted pulp exposure in a tooth with immature roots, a biological method of treatment or a vital amputation is used (if it has passed not more than 6 hours after the trauma). If the pulp exposition area is significant or dotted, but the after trauma time period is 1–3 days, it is necessary to perform a vital amputation In teeth with the mature root a vital or devital pulp extirpation is performed;
