Question 113 · LDEK · Indications and technique
Indicate the true statements regarding tooth removal:
1) surgical division of the periodontal ligament (syndesmotomy) is performed using the Bein straight elevator, periapical curette or dental pliers;
2) beaks of the forceps should firmly grasp the edges of alveolar bone, excluding the situation where there is an unilateral cavity of gingival third, which may cause a crown fracture. In such case there is a need for an elevator or surgical removal of the tooth;
3) oscillating movement, which is applied in buccoocclusal direction, is used for extracting upper premolars;
4) when removing the roots of teeth which transection resembles a circle (such as lower incisors, upper mesial incisor) it is sensible to use rotational or half-rotational motion.
