“…Mineralised tissues produced during apexification can include bone, cementum, dentin or osteodentin (14,19). After trauma, if portions of the formative cells of the periapical area remain vital, then some degree of apexogenic activity may be anticipated which can advance root lengthening (8). These formative tissues include stem cells of the apical papilla (SCAP) and cells from Hertwig’s epithelial root sheath (HERS) (20).…”

“…Treatments that promote root‐end closure or encourage radicular elongation in traumatised immature teeth include strategies employing calcium hydroxide (CH), mineral trioxide aggregate (MTA), other calcium silicate cements (CSCs) or regenerative endodontic treatments (RETs). Recent investigations have shown that MTA apical plug placement, paired with composite restorations, shows remarkable success in providing predictable treatments that retain traumatised immature devitalised teeth for extended periods (4–8). Moreover, outcome studies of various treatment modalities that encourage root‐end closure have shown MTA apical barriers to be a comparable option to RET’s and CH procedures for immature teeth (9–11).…”

Apexification strategies in traumatised non‐vital immature permanent teeth can promote root‐end closure and continued root development. However, traumatic injuries may compromise the integrity of generative cells of the apical papilla responsible for root maturation. This report describes the long‐term treatment outcome of mineral trioxide aggregate (MTA) apexification managed with late‐term surgical intervention. A seven‐year‐old male reported with swelling and suppuration associated with a traumatised maxillary left central incisor (#21). After palliative treatment and MTA apexification procedures, the incisor demonstrated normal function during a 14.5‐year period with radiographic evidence of atypical radicular elongation. Seventeen years after initial treatment, the patient presented with mid‐plate buccal swelling and surgical treatment was completed involving root resection, biopsy of a spherical mineralised tissue specimen and placement of MTA root‐end filling. Periapical healing and normal tooth function was evident at the 20‐year review.

“…The exclusion criteria include the following: [1] patients with systemic disorders and bone metabolic diseases such as diabetes, osteoporosis or hypo/hyperparathyroidism and using a medication; deep pockets with generalised chronic periodontitis in teeth (>3 mm); sinus tract swelling; tenderness on palpation and percussions; enlargement of periapical lesion; multiple roots and canals; external/internal resorptions; root fractures; and apical resections, [2] cases treated less than 1 year ago [3] and images with any intraosseous pathology.…”

“…The MTA plug shows good clinical success with immediate obturation and rigid barrier formation and addition. Recent publications have reported that the MTA plug allows for greater root development [2, 7]. However, it does not provide an increase in root sizes that are prone to fracture [8].…”

Fractal analysis (FA) is a quantitative, objective and non‐invasive method that facilitates the characterisation of the tissue architecture. This study aims to compare the periapical healing at 1‐year follow‐up by evaluating newly generated trabecular bone with FA after Mineral trioxide aggregate (MTA) plug and regenerative endodontic treatment (RET). A total of 55 asymptomatic teeth with a single‐canal, open apex and periapical lesion, treated with MTA plug or RET, were evaluated retrospectively. After considering the inclusion/exclusion criteria, FA was conducted on 30 periapical images using the box‐counting method. In both groups, a significant decrease was observed in the periapical lesion size at 1‐year follow‐up (p < 0.01). However, there was no significant difference between the MTA plug and RET (p > 0.01). Significantly higher fractal dimension values were detected at 1‐year follow‐up in both MTA plug and RET cases (p < 0.01). However, the difference was not significant between the groups (p > 0.01). Both procedures seem to improve periapical healing with a new resistant bone of similar density and complexity.

“…Apical plug is described as non-surgical compaction of biocompatible material into the apical portion of the root canal that prevents the infiltration of toxins and bacteria into periradicular tissues [11,12]. This barrier enables the placement of an appropriate root canal sealant and filling material while reducing the possibility of their extrusion into periapical tissues, preventing overfilling and promoting periapical healing [7,12,13].…”

Apical Sealing Ability of Two Calcium Silicate-Based Sealers Using a Radioactive Isotope Method: An In Vitro Apexification Model

The aim of this study was to evaluate and compare the sealing ability of two calcium silicate-based sealers (TotalFill BC RRM Fast Set Putty and White ProRoot MTA) when used as apical plugs in immature teeth through nuclear medicine. Single-rooted extracted teeth (n = 34) had their crowns and root tip sectioned to obtain 14 mm long root segments to simulate an in vitro apexification model. Were created two experimental groups, namely MTA (n = 12) and BC (n = 12), and two control groups, PG (positive group, n = 5) and NG (negative group, n = 5). On the 4th day after placing the respective apical plug, the apical portions of the teeth were submerged in a solution of sodium pertechnetate (99mTcNaO4) for 3 h. Statistical analysis showed a significant difference between the MTA group and the controls (p < 0.05). The BC group had a significant difference regarding the negative control (p < 0.001) but showed no statistical significance regarding the positive control (p = 0.168). There was a statistically significant difference (p = 0.009) between the BC group (7335.8 ± 2755.5) and the MTA group (4059.1 ± 1231.1), where the last showed less infiltration. Within the limitations of this study, White ProRoot MTA had a significantly better sealing ability than TotalFill BC RRM Fast Set Putty.

Abstract: Unexpectedly, a regeneration of mineral tissues beyond the MTA plug occurred which is an uncommon outcome.
