“…It was reported that calcium hydroxide gutta-percha points improved leakage qualities of zinc oxide-eugenol sealers, Endomethasone and Grossman cement (16). When an intracanal calcium hydroxide dressing is employed it is possible to observe less leakage with the sealers AH 26, Fill Canal and Tubli Seal (13)(14)(15)17), but we do not know if the same will occur with the guttapercha points containing this substance.…”

“…For this motive, the presence of calcium hydroxide residue was investigated with the objective of evaluating if they modify the quality of the root canal filling (12). It has been reported that after use of a calcium hydroxide dressing, there is less leakage in root canal fillings with different sealers (5,13,14). This was also observed when this medication was employed as an apical plug (15).…”

“…Various hypotheses have tried to explain the mechanism action of this drug when less leakage is observed (14,15). In the case of gutta-percha points, it is possible that an expansion of the sealer could occur when in contact with the alkaline pH of the points (16).…”

The objective of this research was to determine if gutta-percha points with calcium hydroxide [Ca(OH) 2 ] improve the apical seal after root canal filling and if the master point does it alone. Human single recently extracted teeth were biomechanically prepared and the root canals filled by the lateral condensation technique with ZOE and gutta-percha points, with or without calcium hydroxide. The teeth were placed into a 2% methylene blue solution in a vacuum environment for 24 h after which they were processed for stereomicroscope evaluation. Better results were observed with the teeth filled with gutta-percha points with calcium hydroxide (p=0.01). We conclude that these new points make a better apical seal and that these results can also be obtained with the calcium hydroxide master point associated with regular ones (p=0.05).

“…Some research has shown that the remains of calcium hydroxide on the dentinal walls had no significant effect on MTA microleakage 8 . In contrast, others have suggested that the remnants react and form calcium carbonate, which interferes with apical sealing 19 .Others have suggested that the combination of calcium hydroxide and MTA in apexification procedures may favorably influence the regeneration of the periodontium 9 . In teeth with chronic periapical lesions, there is a greater prevalence of Gramnegative anaerobic bacteria.…”

Abstract:The periapical area in teeth with chronic lesions is characterized by changes in the adjacent bone structure and periodontal ligaments, as well as in the cement and dentine. In a large percentage of cases, the apical physiological constriction is ether absent or expanded. The absence of a constriction makes it a challenge to achieve satisfactory treatment results.The present case report describes the re-treatment of a case of a mandibular molar, complicated by lack of constriction and a separated endodontic instrument. Mineral trioxide aggregate (MTA) was used for a 5-mm apical plug to avoid overfilling of the sealer when the root canal was definitely obturated. The periapical radiographs showed satisfactory images of periapical bone density and the tooth was asymptomatic on precision. MTA is proved to be an appropriate material for apical sealing in cases with resorption, as it leads to avoidance of apical surgical procedures with a similar prognostic outcome.

“…After its use, Ca(OH) 2 should be completely removed from the root canal walls to obtain an adequate permanent root canal obturation. 10 The hypothesis of this work is that after its use Ca(OH) 2 can not be removed completely from within root canals. Thus, the objective of the present article was to evaluate the interference of the intracanal medication Calen ® (SSWhite, São Paulo, Brazil) in the filling of simulated lateral canals, by means of the thermoplasticization technique.…”

Aim:To evaluate the interference of the intracanal medication Calen ® (SSWhite, São Paulo, Brazil) on the filling of simulated lateral canals. Materials and methods:Twenty human anterior teeth were used. Before the endodontic filling procedures the access of cavity was made, and after this root canals were made in all the teeth to simulate the presence of lateral canals. After preparation, the teeth were randomly divided into two groups (n=10). In group I, the root canal system was filled directly after chemicalmechanical preparation; in group II, endodontic treatment was performed in multiple sessions, and after preparation the calcium hydroxide-based intracanal medication Calen ® was inserted. After the period of 7 days, the root canals were vigorously irrigated and then they were filled. Next, the teeth were radiographed to verify the quality of the filling. Results:The results demonstrated that the teeth treated in a single session, without calcium hydroxide medication, presented 47 canals out of 60 with radiographic evidence of filling, whereas the teeth in which intracanal medication was used, only 07 presented a radiographic image compatible with filling (p < 0.05). Conclusion:The use of the calcium hydroxide-based medication Calen made it difficult to obtain a hermetic filling of the root canal system. Clinical significance:The clinical significance of this work basing on the fact that once the dentist knowing that property obliteration of calcium hydroxide can be taken care when they are used in the presence of lateral canals.
