The wound was packed with sterile gauze and the patient asked to close her teeth together to immobi- lise the pack. Resection of both the mesial and distal roots was performed by bevelling the root tip with a #702 bur in a straight handpiece. Retro- preparation of the mesial root was accomplished using a #1/2 round bur in a contra-angle handpiece with copious irriga- tion. An MTA retrograde filling was placed in the root canals (Fig. 3). Once the extra-oral procedure had been completed the socket was irrigated gen- tly with a normal saline solu- tion to remove the clot and the tooth was replanted. No splint was needed. Six weeks later, the patient was asymptomatic and the re- planted tooth was firm in its socket. At the time, the patient was advised to proceed with the final restoration on the re- planted molar (Figs. 4–8). After one year (Fig. 9), three years (Fig. 10), four years (Fig. 11) and eight years (Fig. 12), the patient attended for evalu- ation and radiographs were taken of the tooth. The radio- graphs showed no evidence of resorption and the patient was asymptomatic. Discussion Intentional replantation is an accepted endodontic pro- cedure in cases in which intra-canal and surgical en- dodontic treatments are not recommended. Although not frequently used, IR is a treat- ment option that dentists should consider under these conditions. If the standard protocols during IR are not followed, root resorption and ankylosis may be observed within one month and one to two months, respectively.17,18 Most resorptive processes are diagnosed within the first two to three years. However, al- though rare, new resorptive processes could occur even af- ter five or ten years.17 As various investigators re- port varying success rates, it is difficult to predict the outcome for IR. Bender and Rossman19 eval- uated 31 cases with an overall success rate of 80.6 per cent (six recorded failures). Re- planted teeth survived from one day to 22 years. A second mandibular molar that failed after three weeks was replant- ed successfully a second time with no signs of failure after 46 months of follow-up. Majorana et al.20 followed 45 cases of dental trauma for five years, recording compli- cations and responses to treat- ment. Root resorption was ob- served in 45 cases (17.24 per cent). Of these, nine were as- sociated with luxation injury (20 per cent) and 36 (80 per cent) with avulsion. The au- thors identified 30 cases of in- flammatory root resorption (18 transient and 12 progressive) and 15 cases of ankylosis and osseous replacement. Aqrabawi18 evaluated two cases of IR and retrograde filling of mandibular second molars. At the five-year re- call visit, radiographs showed no evidence of pathological changes. Nuzzolese et al.21 state that the success rate of IR at five years reported in the literature ranges from 70 to 91 per cent. Al-Hezaimi et al.22 treated a radicular groove that predis- posed a 15-year-old girl to a severe periodontal defect with a combination of endodontic, IR and Emdogain (Straumann) therapy. At the one-year fol- low-up, the patient was com- fortable and active healing was evident. Demiralp et al.23 evaluated the clinical and radiographic results of IR of periodontally involved teeth after condition- ing root surfaces with tetracy- ‘Six weeks later, the patient was asymptomatic and the replanted tooth was firm in its socket’ VOCO GmbH · Anton-Flettner-Straße 1-3 · 27472 Cuxhaven · Germany · Tel. +494721719-0 · www.voco.com For more information please contact: Greg Parmenter · 07500769613 · info-uk@voco.com VOCO_DentalTribune-UK_Jun14_Futurabond U_210x297.indd 109.05.201412:35:03
