4. Periodontic and Endodontic Instruments


a. General. Apicoectomy is defined as the excision of the apical portion of the tooth root through an opening made in the overlying labial or buccal alveolar bone and oral mucosa. There are indications and contraindications for using this procedure. The dentist will evaluate each case. Surgical techniques, instruments, and materials vary with the operator.

b. Preparation. The dental assistant should make certain that all instruments to be used have been sterilized and are ready. If the patient has received preoperative medication, he must be watched closely. The dental assistant should be alert to any unfavorable reactions during the surgery and report them to the dentist.

c. Procedure. Before this phase of treatment, endodontic treatment of the root canal of the tooth will have been performed. On the day of surgery, the dental assistant should have the patient's radiographs nearby and should prepare the necessary instruments for the operation. During the operation, the endodontic assistant must be prepared to evacuate fluids and material from the site of incision and the floor of the mouth. The assistant's technique of irrigation and evacuation of debris is essential for good visibility. During the suturing, the dental assistant must keep visibility at a maximum and use the scissors to cut suture material after each is tied. He also cleans the patient's face, plans a future appointment, and records postoperative instructions of the dentist.
