In Dhaka 2013, autografts of demineralized dentin matrix (DDM) were first used as bone regenerative therapy with two patients in Bangladesh. In Case 1, a 29 year-old male presented with an infected periapical lesion involving #11 and #12. Root canal treatment followed by periapical surgery were done to remove the lesion. Tooth-derived granules were prepared from a vital non-functional tooth (#38) by hand-operated crush method, demineralized in 2 % HNO 3 for 30 min and washed vigorously. DDM was grafted in the bone defect after the extirpation of the lesion. At 1 year after DDM graft, post-operative radiography indicated excellent bone healing by remodeling with dentin matrix. The pathological diagnosis was radicular granuloma. In Case 2, a 20 year-old female presented with a mesially inclined impacted 3 rd molar (#48). Extraction of the impacted tooth and the autograft of the DDM were done simultaneously. Post-operative radiographs showed the extracted socket healed fully with new bone. The patient-own DDM granules from non-functional teeth could be recycled as osteoinductive materials for local bone regeneration. This works suggest that dentin might become a realistic alternative biomaterial to bone.
A traumatic or irritational fibroma is the most prevalent submucosal reactive lesion in the oral cavity. It forms as a result of irritation or trauma and is composed of fibrous or connective tissue. Although electrical or laser surgery is beneficial for the excision of oral fibroma in patients taking anticoagulant, but these devices may not be available in all clinical settings. This case report aims to demonstrate scalpel excision as an effective and convenient surgical treatment for the management of the fibroma in patient having anticoagulant drug instead of using electrical, laser, or cryosurgery. A female patient, 70 years old, reported to the department with a chief complaint of painless swelling in the right lower posterior tooth region for the past 2 years. On examination, the lesion was found to be a well circumscribed, smooth, tender, firm, and lobulated pink swelling 1x0.8x0.5 cm in diameter positioned on the buccal mucosa of the right molar region. Surgical therapy was carried out by scalpel excision, followed by medication for the management. In compared to electrical, laser, and cryosurgery, scalpel excision was a simple and effective approach to successfully remove the fibroma, and complete healing of the surgical site was observed after 2 months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
