Root-end restoration using Mineral Trioxide Aggregate (MTA) was performed on two patients who received root canal treatment but had poor progress. In one case, a large amount of Calcium hydroxide(Ca (OH)2), a intracanal medicament, escaped from a wide-open apex, stagnated around the tooth root, and the apical lesion did not disappear. The other case is a case where the root canal at the apical part has a complicated anatomical form, the root canal cannot be tightly packed, and the apical lesion has not disappeared. Root-end restoration using MTA was performed on these two cases, and improvement of the lesion was confirmed. From these results, it was shown that Root-end restoration using MTA is effective for patients with poor prognosis of root canal treatment for which the apical portion cannot be tightly packed for various reasons.

In this study, 120 teeth having periradicular pathosis were treated with single visit root canal treatment and then obturated with either calcium hydroxide containing sealer or mineral trioxide aggregate based sealer. The healing of periradicular pathosis was examined at 3, 6, and 12 months by clinical and radiological evaluation. Collected data were analyzed with standard statistical methods by using SPSS version- 20. The results showed that at 3 and 6 months, the differences between calcium hydroxide containing sealer or mineral trioxide aggregate based sealer were not statistically significant. However, the healing capability of periapical radiolucency at 12 months between two groups was statistically significant (P=0.03). The final outcome of the clinical and radiological investigation showed successful results of 96.6% and 98.1% in calcium hydroxide and mineral trioxide aggregate group, respectively. In conclusion, both calcium hydroxide and mineral trioxide aggregate based sealers are almost equally effective in single visit root canal therapy for the management of periradicular pathosis.

Introduction: Irrigation of the root canal is an important part of the endodontic treatment. Root irrigation technique can be done with the manual and sonic system by using 2.5% NaOCI solution. Calcium hydroxide [Ca(OH)2 ] is used as a medicament for root canal sterilization. Root canal treatment will fail due to the imperfect removal of Ca(OH)2 residue. The objective of this research was to analyze the comparison of the removal of Ca(OH)2 medicaments on the root canal treatment irrigated with manual and sonic agitation technique using 2.5% NaOCI. Methods: The methods used in this study was experimental laboratory. The sample used was 30 maxillary incisors. The teeth were then divided into two groups randomly, then the root canal preparation was done by the crown down technique with irrigation using 2.5% NaOCI. The radicular part of the teeth was then split longitudinally, given a standardized groove in the one-third of the apical part, then applied with water-solved calcium hydroxide. The teeth were unified afterwards by using flowable composites, then soaked in the artificial saliva. The sample of the 1st group was irrigated by manual agitation technique, and the 2nd group by sonic agitation technique. The data results were analyzed by Kruskal-Wallis and Mann-Whitney tests. Results: The results of Ca(OH)2 removal were different between manual agitation technique compared to the sonic agitation technique. Conclusion: The irrigation using 2.5% NaOCl with the sonic agitation technique were proven to be more effective in removing Ca(OH)2 from root canals than the manual agitation technique.

ABSTRACT Overinstrumentation during root canal treatment is one of the causes for iatrogenic enlargement of the root apex. It also leads to unwarranted coronal third widening, which results in thinning of the dentinal walls and makes the tooth susceptible to fracture. Another difficulty arises during control of obturation material within the canal. Such cases can be managed with obturation using mineral trioxide aggregate (MTA) followed by of root reinforcement for the weakened dentinal walls. In the present case, a 5mm MTA plug was placed and root reinforcement was done with the help of Giomer. Postendodontic restoration was done with a cast post and a full coverage porcelain fused to a metal crown was cemented in place.

Background: Streptococcus mutans play an important role in occurrence of dental caries objective: to compare the clinical and microbiological antibacterial outcomes of Mineral trioxide aggregate (MTA) and Calcium hydroxide cement Ca(OH)2. Methodology: 20 primary molars in 10 children with year’s 5-9 y .For each child one tooth was treated with Ca(OH)2 and the other with MTA. Finally, all the cavities were restored using compomer restorative material, and then microbiological parameters were recorded. Results: MTA treated teeth did not show any clinical sign or symptoms of failure. While three teeth treated with Ca(OH)2 were excluded because of necrosis. Changes in color and consistency of dentin were nearly the same for both groups. Microbiological evaluation showed a decrease in the count of Str. mutans with calcium hydroxide and complete killing of bacteria with MTA. Conclusion: The treatment showed satisfactory results of MTA as it was more potent inhibitor of bacterial-growth than Ca(OH)2

Abstract Aim and objective: The aim of the present study was to evaluate clinical and radiographic outcome of MTA as a pulpotomy agent in permanent teeth as an alternative to conventional root canal treatment. Materials and Methods: Ten permanent teeth with symptoms of irreversible pulpitis with vital pulp were selected for the study. MTAPulpotomy procedure was done in all the cases using standard protocol. Teeth were evaluated for various clinical and radiographic parameters at 3, 6, 9 and 12 months of follow up. Results: None of the patients reported any kind of clinical discomfort or radiographic abnormality during the follow up period of 3, 6, 9 and 12 months. All the teeth responded positive on electric pulp test at all successive follow ups. Conclusions: MTA Pulpotomy may be used as an alternative treatment modality to root canal treatment in permanent teeth with irreversible pulpitis, if future research continues to show promising results.

Anterior Teeth

Objectives: The aim of the present study was to assess the effect of calcium hydroxide as a root canal dressing material on dentin microtensile fracture strength in human primary teeth in vitro. Study design: Thirty primary anterior teeth with root canals packed with calcium hydroxide were divided into groups of ten and immersed in saline at room temperature for 7, 30 and 90 days. Ten teeth with root canals filled with sterile saline were the control group. Microtensile fracture strength was measured in Mechanical tester Lloyd testing machine. Results: There was a significant difference (P < 0.05) between the fracture strength of the calcium hydroxide-filled teeth after 90 days (19.1 MPa) compared with the control (35.8 MPa). Dentin microtensile fracture strength of the calcium hydroxide-filled teeth decreased at an average of 0.142 MPa per day. Conclusion: Calcium hydroxide placed in root canals for an extended time had a significantly negative effect on root strength. Long-term success of root canal treatment in primary anterior teeth is estimated as 65% with most of the failures result from trauma recurrence. Clinical Relevance: Our results stress the need to evaluate the pros and cons of root canal treatment compared to extractions of non-vital primary incisors.
