Question 221 · LDEK · Indications and technique
Indicate the true statements concerning the extraction of a tooth:
1) surgical division of the periodontal ligament (syndesmotomy) is performed with Bein straight elevator, periapical curette or a pickup;
2) beaks of forceps should firmly grasp the edges of the alveolar process, with the exclusion of one sided class V cavity, threatening with a crown fracture, when there is a need for an elevator or surgical removal of the root;
3) while extracting the teeth which cross sections are close to a circle (lower premolars, medial upper incisor), there is an indication for using rotational or half rotational movements;
4) some difficulty might be encountered while extracting deciduous molars, which thin and hooked roots can sometimes surround permanent tooth germs;
5) extraction may be significantly hindered by abnormally formed roots or a thickened bone of the alveolar process;
6) excochleatio is a procedure performed after each extraction in order to exclude the presence of oroantral communication and to remove fragments of the tooth, the intraseptal bone, granuloma or granulation.
The correct answer is:
2) beaks of forceps should firmly grasp the edges of the alveolar process, with the exclusion of one sided class V cavity, threatening with a crown fracture, when there is a need for an elevator or surgical removal of the root;

- C. 2,3,5,6.
- D. all the above.
- E. 2,3,4,5.
Hint
Recall where forceps beaks are placed relative to the alveolar crest and whether curettage of the socket is routine.
