Abstract

The development of aesthetic rehabilitation techniques or smile design in the field of dentistry has brought a paradigm shift in the field of restoration and aesthetic. Dentists in planning treatment for patients should do a proper analysis on the patient, not just think about the treatment of one tooth, but the whole tooth being the problem in patient’s smile. This case aims to report the paradigm of “smile design” in the aesthetic rehabilitation on maxillary anterior teeth. The 23-year-old male patient came to the dental clinic with complaints of caries on the upper anterior teeth with wide damage. Pulp vitality tests showed positive results on teeth 13, 12 and negative on teeth 14,21,22,24. Radiographic examination revealed radiolucent image until dentin in teeth 12 and 13, as well as radiolucent image until pulp and widening of periodontal membrane on teeth 14,21,22,24. Case management in these patients is smile design analysis on maxillary anterior teeth. Direct composite veneer restoration is performed on teeth 13, 12, while root canal treatment is done on teeth 14, 21, 22 and 24 followed by fiber reinforced composite and all porcelain crowns. Patients is consulted to periodontic department for gingival aesthetic correction treatment with crown lengthening and gingival depigmentation. Aesthetic rehabilitation techniques or smile design involves evaluation of certain elements which is face analysis, jaw-facial relationship analysis, dental relation to the center line of the face, tooth on lips analysis, dental relation to the gingiva, and teeth shape and color analysis.These elements are all interconnected with each other.

Abstract

Root canal treatment in necrosis blunderbluss apices difficult to treat and to obtain a good apical seal. A therapy called apexification is required to induce the formation of a calcified apical barrier. The aim of this case report is to demonstrate apexification blunderbluss apices by the use of mineral trioxide agregat (MTA) as an apical plug and follow up fiber reinforced composite (FRC) after bleaching and direct composite. A 18 year old male patient reported with fractured right central incisor on the incisal with blunderbluss apices and the tooth has brown discoloration. MTA as an apical plug was used after the root canals had been debrided and rinsed with 2,5% NaOCl. Calcium hydroxide paste was placed in the canal before the apical portion of the canal was filled with the MTA apical plug. Bleaching before a FRC was placed in the remaining portion of the canal, core build-up was done and direct composite filled over it. At 6 month follow-up period the clinical and radiographic appearance of the teeth had healed successfully. MTA appears to be a promising alternative to calcium hydroxide apexification because of its superior sealing ability, high biocompatibility, and reduced treatment time. The reinforcement of the composite resins by fibers improves their fracture toughnes and resistance. Bleaching and direct composite to make coronal sealing and tooh color returned to the original color. MTA in apexification is valuable method if the quality of coronal sealing can be enhanced.

Abstract

Introduction: Ethylene Diamine Tetra Acetic Acid (EDTA) 18% irrigation solution is one of the chelating agents that able to remove calcium hydroxide (Ca(OH)2) from the root canal wall. Failure of root canal treatment can be caused by the presence of residual calcium hydroxide in the root canal wall, thus blocking the bond between the medication and root canal filling material with the root canal wall. This study was aimed to observe the EDTA 18% flow in removing the Ca(OH)2 using CFD analysis. Methods: This research was descriptive. Cleanliness of the root canal wall from Ca(OH)2 medicament using EDTA 18% irrigation was analysed using the CFD method with test specimens in the form of resin blocks made according to the characteristics of the root canal. The irrigation needle used was side-vented with a position of 3 mm from the apical tooth. Stage analysis of root canal geometry was performed using Computational Fluid Dynamics (CFD) analysis to observe the characteristics of irrigation solutions in root canals in 3D. Results: The streamlined characteristics of EDTA 18% irrigation solution showed a unique behaviour due to the features of the side-vent shaped irrigation needle. Irrigation flow in the crown area of the inlet (side-vented irrigation needle) showed low velocity so that the fluid flow when exiting the inlet was more towards the apical than the outlet (root canal orifice). Conclusion: Velocity and wall shear stress of EDTA 18% showed the results validation conformity between experimental and CFD, that the maximum velocity of EDTA 18% is 19 ms-1 and EDTA 18% wall shear stress is 1.56 KPa for calcium hydroxide removal observed from the CFD study. Keywords: Computational fluid dynamics, EDTA 18%, calcium hydroxide (Ca(OH)2), velocity, wall shear stress

Abstract

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.
