“…Further studies are needed to determine whether this difference is clinically significant, or whether MTA could provide a treatment option in cases of external inflammatory root resorption (16). Interestingly, a recent study demonstrated upregulation of bone morphogenetic protein-2 gene expression in human periodontal ligament cells exposed to MTA for 4 weeks, suggesting a possible role for the material in the healing process of periodontal tissues (39).…”

“…As with CH, it shares a similar highly alkaline pH when freshly mixed (13) and demonstrates some antimicrobial activity (14,15). In a recent case report with a 48-month recall, a case of severe inflammatory resorption was successfully managed by obturating the canal with MTA (16).…”

“…This aseptic environment induced healing of the defect, rather by bone formation, in the present case, because of dental and periodontal cell damages (28). Recently, MTA has been reported to be effective in the management of inflammatory root resorption (29, 30).…”

We report a case of multiple dental traumas in a 15-year-old school boy who was hit by a stone. Clinical examinations revealed the avulsion of teeth 21, 22, and 23, an uncomplicated crown fracture of tooth 41, and a complicated crown fracture (CCF) of teeth 11, 31, and 33. An alveolar bone fracture and a root fracture in the apical third of tooth 23 were as well noted on radiographs. The avulsed teeth were replanted and rigidly splinted after an extraoral dry time of 90 min. Endodontic treatments were performed on teeth with CCFs. The dental morphology was restored using polyethylene fiber-reinforced composite resin. Endodontic obturations were performed on replanted teeth after the arrest of external root resorptions by a long-term calcium hydroxide dressing. Esthetics and function were recovered with a 2.5-year follow-up period.

“…Of high interest, a study conducted by Holland et al [18] demonstrated that MTA shares several beneficial properties with calcium hydroxide. MTA has also been successfully used as a permanent obturation material following tooth traumatic injuries, such as luxation, intrusion or avulsion [19]. Nevertheless, only few clinical studies have evaluated the long-term outcome of MTA-obtured traumatized tooth [14,20,21].…”

Evaluation of two formulations containing mineral trioxide aggregate on delayed tooth replantation: relevance of RANKL/RANK/OPG system

et al. 2015

This study aimed to evaluate the effects of White MTA (WMTA) and MTA Fillapex(®) on root resorption, when used for root canal filling, in a rat model of delayed tooth replantation, with special focus on the RANKL/RANK/OPG system. Maxillary right central incisors of male rats were extracted (total N = 48), and exposed to dry environment for 30 min. The animals were allocated into four groups: (1) WMTA; (2) MTA Fillapex; (3) Calcium hydroxide; (4) Negative control. After periodontal ligament removal, root canals were filled with the corresponding material and replanted. After 10 and 60 days, qualitative and semi-quantitative histological and immunohistochemical analyses were carried out. Analysis of variance (ANOVA) with Tukey's post hoc adjustment was used, at 10 and 60 days, to compare the experimental groups in terms of the inflammatory scores and in terms of the changes in OPG, RANK and RANKL. Both WMTA and MTA Fillapex groups displayed inflammatory and replacement resorption, with the presence of dento-alveolar ankylosis, similarly to that observed for calcium hydroxide, in either 10 or 60 days. Notably, a slight increase of the inflammatory process was observed in both MTA groups. Quantitatively, inflammation score analysis showed a significant difference between the calcium hydroxide and the control group at 10 days. On 60 days, dento-alveolar ankylosis was found significantly increased in the MTA Fillapex, in comparison to the control group (p < 0.05). For immunohistochemical analysis, the expression of both RANK and RANKL was reduced in calcium hydroxide and WMTA groups, from 10 to 60 days of evaluation, an effect that was accompanied by increased OPG immunolabelling. Otherwise, the MTA Fillapex group presented a general increase of RANKL immunopositivity, similarly to that observed in the negative control group. Our data showed that none of tested materials was able to fully prevent the root resorption, although the white MTA cement presented an outcome comparable to that seen for calcium hydroxide. MTA cements might present some advantages when considering no need of frequent changes, although the effects of MTA cements in dental avulsion still require further investigation.
