biodentine pulpotomy vs metapex pulpectomy in primary molars: clinical & radiographic comparison of outcomes in irreversible pulpitis cases

Conditions: Dental Caries

Summary: irreversible pulpitis is defined as a clinical diagnostic based on subjective and objective findings suggesting that the vital inflamed pulp is incapable of healing in the american association of endodontists (aae) consensus conference recommended diagnostic terminology. other characteristics include persistent heat discomfort, transferred pain, spontaneous pain, or no clinical symptoms but caries-induced inflammation, caries excavation, and trauma.". dental caries is one of the most frequently occurring diseases affecting human beings that becomes a challenge for dentists as the disease progresses. the ultimate goal of operative and endodontic treatment is to preserve and maintain the vitality of pulp to allow continued development of odontogenic apparatus.

pulp interventions combine a medication with a pulp treatment technique. preserving the health of the tooth and its supporting tissues is the aim of these procedures. three pulp therapy options are available, depending on the severity of the disease: pulpectomy, pulpotomy, and direct pulp capping. direct pulp capping includes applying a medicinal material directly to the exposed pulp; pulpotomy and pulpectomy require removing parts of the pulp or the entire pulp in the pulp chamber and root canal of the tooth. in these procedures, the caries and part of pulp tissue are removed, and then medications are applied. this method aids in preserving the tooth's transient integrity. when more advanced caries lesions approach the pulp-dentin complex and produce pulp necrosis, endodontic therapy is one way to save primary teeth until exfoliation. maintaining the child's primary teeth in their oral cavity while getting rid of any symptoms or indicators is the ultimate goal of endodontic therapy in pediatric dentistry (afroz et al., 2019). zinc oxide eugenol (zoe) was introduced in 1930 and has been the conventional and widely approved root canal filling material for primary teeth. with over 90% of cases successfully reported, studies using zoe paste have shown moderate to high success rates. but it has some drawbacks as well, such as the slower rate of resorption than the root, the possibility of the developing successor teeth becoming misaligned, particularly in overfilled cases, and worries about the material's potential for reduced antibacterial activity after the material is set in place. because zinc oxide eugenol has some disadvantages, biodentine-which may be utilized in direct contact with pulpal tissue-has strong mechanical properties, a good capacity to seal with dentine, and a biocompatibility that is comparable to that of mta. it fulfilled every requirement of the perfect restorative material, including patient acceptance, good mechanical and physical properties, technical elements from the dentist's perspective, and other clinical characteristics that enhanced the material's efficacy. if only a portion of the odontoblastic layer is damaged, biodentine may accelerate pulp repair and regeneration. for primary teeth pulpectomy, metapex (metapex, meta dental, new york, usa) is an easy-to-apply option that combines iodoform and calcium hydroxide. according to studies, this material has a good rate of resorption, less void formation, and excellent clinical and radiographic results.
