Telephone: +2010066444572 Email: (mai_mamdouh@dentistry.cu.edu.eg) Objective: The aim of this trial was to assess the effectiveness of partial caries excavation technique with and without prior application of Nano-silver fluoride (NSF) solution on the quality of the remaining carious dentin, after 6 months follow up. Methods: Twenty-two patients having two contralateral deep occlusal carious molars with no signs of pulpal inflammation were recruited. The 44 cavities were prepared with partial caries excavation technique. Where, in group A; 0.2 ml of NSF solution was applied in the cavity and agitated for 2 minutes prior to the restoration. While, for group B; Glass ionomer (Equia forte) was directly applied into the cavity. Standardized digital periapical radiographs were taken at baseline and after 6 months. The carious dentin density and the dentin bridge formation were calculated using Digora for Windows (DFW) 2.5 software program. Comparison between the study groups was done using Mann Whitney U test for independent samples. Within group comparison between baseline and 6 months values was done using Wilcoxon Signed Rank test for paired samples. Results: Statistically significant increase of both the dentin density and the dentin bridge thickness was found for both groups after 6 months compared to baseline (p=0.001). However, the percentage change in the density after 6 months was significantly higher for group A that reached more than double that of group B (p= 0.008). While, no differences were found between both groups in the dentin bridge thickness (p= 0.885). Conclusions: Partial caries excavation for deep carious lesions showed significant remineralization of carious dentin and increase in dentin bridge thickness. Furthermore, NSF solution noted to be a promising agent helping in caries arrest.

Clinical And Radiographic Assessment Of Platelet Rich Fibrin And Mineral Trioxide Aggregate As Pulp Capping Biomaterials A Randomized Controlled Clinical Trial

PHD Abstract

This study was conducted to assess the clinical success and radiographic regenerative dentin formation of mineral trioxide aggregate (MTA) with and without platelet-rich fibrin (PRF) when used as a direct pulp capping agent. The success of vital pulp therapy treatment through direct pulp capping preserves tooth vitality, structure and reduces the need for endodontic treatment. Thus, decreasing cost, complaint, and effort in the expense of treatment One hundred and eight patients (108 teeth) with exposed pulp during operative caries management by undergraduate students were enrolled after ensuring that they met inclusion criteria, especially controlled bleeding, isolated operative field by rubber dam at the time of exposure and teeth diagnosed with reversible pulpitis. After that, patients who agreed to participate in the trial signed the informed consent. The subjects were randomly divided into 2 groups as follows: • Group I (n= 54) represents the comparator group where teeth will be treated with direct application of MTA over exposed pulp, • Group II (n=54) represents teeth to be treated with the application of PRF directly over exposed pulp followed by MTA application. MTA was mixed according to the manufacturer’s instructions and was applied over the exposed pulp. In the intervention group, Autologous PRF was obtained from a centrifuged patient's blood sample (5ml) that was cut into small pieces to be implemented over the pulp exposure site, followed by MTA application, compared to direct application of MTA over the exposure in the control group. In both groups, a saline-moistened cotton pellet was laid directly over MTA and the treated teeth were provisionally restored with a temporary filling. Patients were recalled after 5 days to 1 week to give a chance for complete setting of MTA and placement of final restoration (GIC was placed as a liner and resin composite final restoration) was performed. Postoperative follow-up: The subjects were analysed at 6 and 12 month intervals for clinical and radiographic assessment. The clinical success of treatment in both groups was assessed by pulp sensibility tests (thermal and electrical), a history of pain, a percussion test, and Clinical and Radiographic assessment of any signs and /or symptoms of pulp necrosis or apical periodontitis (abscess, edema, swelling, 198 periapical pathosis). CBCT assessment was done at 12 months only to evaluate dentin bridge formation and ascertain periapical tissue health. According to the results obtained, both groups showed equal clinical success rates after 12 months of follow-up (92.59 %). However, dentin bridging was more significant when PRF was applied prior to MTA. It could be concluded that PRF seems to be a promising pulp capping agent and can be implemented as a direct pulp capping agent in upcoming clinical applications.
