Early carious lesions induce odontoblast stimulation in tertiary dentine formation even before the lesion reaches the dentine. The most used material for these procedures was calcium hydroxide, which was recently replaced by Mineral Trioxide Aggregate (MTA).The purpose of our study was to assess the histological characteristics of tertiary dentine induced by these materials in permanent molar teeth.We used 23 molars scheduled for extraction due to orthodontic reasons, in patients of 17-24 years of age. In a time interval of 4-8 weeks prior to extraction, occlusal cavities were prepared and filled with MTA or calcium hydroxide and glass ionomer cement.In teeth filled with MTA we noticed an early development of tertiary dentin layer, with a tubular structure, similar to secondary dentine. In the case of calcium hydroxide, the process of new dentine deposition was delayed and diffuse calcification, with formation of pulp stones was noticed.MTA proved to be superior to calcium hydroxide in inducing tertiary dentine formation, which appeared early after treatment. In time the differences in the amount of tertiary dentine between these materials are reduced, but there is a tendency of diffuse mineralization induced by calcium hydroxide.

<p>The maintenance of pulp vitality and conduction of reparative dentin can be possible by indirect pulp capping with mineral trioxide aggregate (MTA) and calcium hydroxide as pulp capping agents. The objective of the study is to assess the clinical and radiological outcomes of MTA and calcium hydroxide as indirect pulp capping agents in deep carious lesions of permanent teeth. The present study included 50 permanent teeth having deep carious lesions with reversible pulp status were selected and then randomly divided into two groups of 25 teeth in a group. Standard indirect pulp capping procedures were followed. Patients were recalled at 3, 6 and 12 months interval to assess postoperative pain, the vitality of the pulp and formation of reparative dentin. In all observation periods, MTA showed more capable of reducing pain and maintain pulp vitality which was statistically significant than that of calcium hydroxide. At 12 months observation period, 24 teeth (96%) of MTA and 19 teeth (76%) of calcium hydroxide showed reparative dentin formation. It can be concluded that MTA is more effective than that of calcium hydroxide.</p><p> </p>

SUMMARY Objective: This clinical study aimed to assess the efficacies of mineral trioxide aggregate (MTA) and calcium hydroxide [Ca(OH)2] in the treatment of deep carious lesions by the direct complete caries removal technique. Methods and Materials: A total of 100 permanent molar/premolar teeth were capped with either Ca(OH)2 (n=49) or MTA (n=51) and restored with composite resin in 73 patients. Periapical radiographs were acquired prior to the treatment as well as at six, 12, and 24 months posttreatment. Two calibrated examiners performed the clinical and radiographic assessment of the periapical pathology and pulpal symptoms. Intergroup comparisons of the observed values were performed using the Fisher exact test. Significance was predetermined at α = 0.05. Results: The recall rates were 100% at six and 12 months posttreatment and 98.6% at 24 months posttreatment. Four teeth capped with Ca(OH)2 (two each at six and 12 months posttreatment) and two capped with MTA (one each at 12 and 24 months posttreatment) received endodontic emergency treatment because of symptoms of irreversible pulpitis, which were clinically and/or radiographically established. There were no significant differences in pulp vitality between the two pulp-capping agents at six, 12, or 24 months posttreatment (p=0.238, p=0.606, and p=0.427, respectively). Conclusions: Both pulp-capping materials were found to be clinically acceptable at 24 months posttreatment.

Aim: To evaluate the clinical success of Calcium Hydroxide (CH), Mineral trioxide aggregate (MTA) and Biodentine as pulp capping materials for Direct pulp capping in carious molars. Materials and Methods: Thirty-six molars of thirty-six patients with deep caries lesions, diagnosed with reversible pulpitis were subjected to direct pulp capping treatment. They were randomly divided into three groups, Biodentine (12 teeth) or MTA group (12 teeth) or CH group (12teeth). Simple randomization of three was employed to allocate the treatment materials. Patients were recalled at one, three and six months to evaluate the clinical success of the treatment outcome. Results: In clinical trial/study, the pulp capping materials gave different success rate, 91.67% success in the Biodentine group, 75% success in the MTA group and 41.67% success in Calcium Hydroxide group. Conclusion: In our study the materials tested at 1 month, 3 month and 6-month follow-up, Calcium Silicate materials are better than calcium hydroxide and comparably Biodentine is better than MTA for Direct pulp capping. Clinical Significance: The findings of this clinical trial could promote the reliability of pulp capping materials for treatment of deep carious lesions by conservative approach rather than opting endodontic management.

The objective of this study was to measure temperature changes in the pulp chamber induced by polymerization of resin-based dental restoratives following a simulated procedure of direct pulp capping. Class I cavities with a microperforation at the pulp horn were prepared in extracted human molar teeth. The complete procedure of direct pulp capping and cavity restoration was performed with the root part of extracted teeth fixed in a water bath at 37 ?C. Mineral trioxide aggregate, bioactive dentin substitute or calcium-hydroxide paste were used as pulp capping materials. Cavities were restored with a light-cured or chemically-cured resin-modified glass ionomer, universal adhesive and a bulk-fill composite, cured with a high-intensity LED unit. Pulp capping materials caused a slight temperature decrease. Lower temperature increase was recorded during light-curing of the glass ionomer liner after direct capping with mineral trioxide aggregate and calcium-hydroxide than that recorded for the bioactive dentin substitute. Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5?C.

Abstract Background: Intensified preventive regimen based on a ‘high-risk’ approach has been proposed instead the routine prevention that is generally given to the whole population. The effectiveness of these regimens may still be an issue. Therefore, the aim of this study was to compare two preventive programs carried out in a Public School for kindergarten children. Methods: The data from clinical examinations were used to assess the caries risk for 121 children. Children with at least 2 carious lesions were considered as high risk for dental caries development. These children were randomized into two groups. Half (High risk basic-HRB group) were provided the basic prevention regimen (oral-hygiene instruction and hands-on brushing practice for teachers and caregivers, daytime tooth brushing supervised by teachers at least once a week, newly erupted first permanent molar sealant, provision of toothbrush, fluoride-containing dentifrice, and a guidebook), which was also given to low-risk children (Low risk basic-LRB group). The other half (High risk intensive-HRI group) were additionally given an intensified preventive regimen (F-varnish application, primary molar sealant, and silver diamine fluoride (SDF) application on carious lesions). Clinical examinations were performed semiannually to determine the dmfs caries increment of the three groups. Results: The 89 children completed the 24-month examination were 3- to 5-year-old with 19, 35, and 35 children in the LRB, HRB, and HRI group, respectively. The new caries development at 24 months of the HRB group (75%) was higher than that of the HRI group (65.7%) and the LRB group (21.1%). One-way analysis of variance (ANOVA) indicated no significant differences of caries increment between the HRB and HRI groups at the end of our study ( p =0.709). Conclusions: The negligible difference in caries increment between the HRI and HRB groups implies that intensified prevention produced minimal additional benefit. Offering all children only basic prevention could have obtained virtually the same preventive effect with substantially less effort and lower cost.

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.

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
