apexification using biodentine

a case report with using biodentine for apexification

1. ENDODONTIC MANAGEMENT OF OPEN APEX USING BIODENTINE AS A NOVEL APICAL MATRIX

2. CONTENTS INTRODUCTION CASE REPORT DISCUSSION CONCLUSION REFERENCES

3. INTRODUCTION Biodentine - calcium silicate based cement. Physical and chemical properties - Portland cement derivatives. Biocompatibility Bioactive dentin substitute Root perforations Apexification Retrograde root filling A modified powder composition, the addition of setting accelerators and softeners, and a new predosed capsule formulation for use in a mixing device, largely improved the physical properties of this material making it much more user-friendly with a shorter setting time. Therefore, present case report highlights the nonsurgical management of teeth with immature apices and large periapical radiolucencies using biodentine matrix to promote periapical healing.

4. CASE REPORT 25 -year-old male H/O - Trauma Non- vital Radiographic examination

5. Endodontic access The working length. Biomechanical preparation was done using No: 80 K-file Root canal debridement The root canal was then dried with sterile paper points. Calcium hydroxide - recalled after 1 week.

6. → Biodentine : five drops of liquid - triturator for 30 s. → The material was then delicately pushed towards the apex with a root-canal plugger . → Several increments were required to form a plug of adequate thickness → After verifying that the material was hard-set → Gutta-percha obturation was performed using obtura II and the access cavity was sealed using composite resin.

7. → The clinical follow-up at 18 months showed the patient functioning well with no reportable clinical symptoms and the absence of any sinus tract formation. → The radiographic follow-up showed complete healing of the periapical radiolucency and regeneration of the periradicular tissues. PRE-OPERATIVE POST-OPERATIVE

8. DISCUSSION The goal of this treatment is to obtain an apical barrier to prevent the passage of toxins and bacteria into periapical tissues from the root canal. Technically, this barrier is necessary to allow compaction of root filling material. Despite higher success rate of apical barrier formation using calcium hydroxide , long term follow-up is essential. Using a suitable biocompatible material reduces leakage in the sealing material and allows favorable response of the periodontal tissues for periapical healing and apexification . APEXIFICATION 'a method to induce a calcified barrier in a root with an open apex or the continued apical development of an incomplete root in teeth with necrotic pulp‘ (American Association of Endodontists ). BIODENTINE

9. Laurent et al. investigated the capacity of Biodentine to affect transforming growth factor-β1 (TGF-β1 ) secretion from pulp cells CONCLUSION: Biodentin caused a significant increase of TGF-β1 secretion from pulp cells, thus inducing an early form of dental pulp mineralization shortly after its application.

10. HAN AND OKIJI compared calcium and silicon uptake by adjacent root canal dentine in the presence of phosphate buffered saline using Biodentine and ProRoot MTA . RESULTS: Both materials formed a tag-like structure composed of the material itself or calcium-or phosphate rich crystalline deposits. The thickness of the Ca -and Si-rich layers increased over time, and the thickness was significantly larger in Biodentine compared to MTA after 30 and 90 days CONCLUSION: Dentine element uptake was greater for Biodentine than for MTA.

11. KOKATE AND PAWAR compared the microleakage of glass ionomer cement, MTA and Biodentine when used as a retrograde filling material CONCLUSION: Biodentine exhibited the least microleakage when compared to other materials used. Research suggests that a high pH and released calcium ions are required for a material to stimulate mineralization in the process of hard tissue healing.

12. SULTHAN evaluate the pH and calcium ion release of MTA and Biodentine when used as root end fillings. CONCLUSION: Biodentine presented alkaline pH and ability to release calcium ions similar to that of MTA . The 24-h push-out strength of MTA was less than that of Biodentine. Blood contamination affected the push-out bond strength of MTA irrespective of the setting time.

13. CONCLUSION This case report emphasizes the novel approach of using Biodentine to achieve single visit apexification of the cases with an open apex and large periapical lesion. The use of Biodentine has been demonstrated to induce faster periapical healing for single visit apexification of the cases with large periapical lesions. Although the efficacy of BioDentine as a dentin substitute is yet to be clinically proven for its therapeutic indications, it may be a promising material for apexification.
