procedures are performed on the M aspect of the M root of 47 – with similar characteristics to those described above – with the aid of sonic diamond inserts.
Figure 23 Image of the quadrant after elevating the flaps, osseous-resective surgery, preparation of the external resorption lesions D44, M45, M47. Tooth 46 shows no lesions. The adequate vasoconstriction induced by the anaesthetic with 1:100000 adrenaline, the accuracy of execution, the correct incision of the flaps, the effect of the cut produced by the sonic instruments used for 370

resective surgery made it possible to obtain a clean surgical field with low bleeding, prerequisite to be able to perform intraoperative field isolation. Figures 24-26 One of the most demanding stages of the
procedures consists in the isolation of the intraoperative field. According to the method proposed by the Author, a cellulose-based paste isolating material is used (OraSeal Caulking, Ultradent), applied directly on the osseous tissue below the elevated flaps. A premolar clamp is then used for stabilising (Ivory no.1; Fig. 26) on root M of 47 with self-adhesive flowable composite.
