Rapports de cas de santé bucco-dentaire

Low-grade myofibroblastic sarcoma (LGMS) is a rare, mesenchymal malignant tumor with myofibroblastic differentiation. It has been reclassified as a distinct entity in the newly published World Health Organization classification. Only a few cases have been reported in the oral and maxillofacial region. Here, a LGMS developed in the right retromolar region of a 12-year-old boy who presented with a mass of 2.5 cm × 1 cm × 1 cm size. Based on the histological and immunohistochemical findings, a diagnosis of LGMS was established. The tumor was resected, and no recurrence was observed over one year. Follow-up is essential for early recognition and intervention of late recurrence and metastases.

Aim: The mean goal of this article is to evaluate the pain after using of intracanal medications; calcium hydroxide and Ledermix with 5.25% sodium hypochlorite irrigating solutions utilizing Visual Analogue Scale.
Material and methods: 44 patients dividing into two groups then into two visit treatment which the first visit access cavity was performed after anesthesia and cleaning and shaping by using perotaper universal with irrigation protocol and then canal dried then either calcium hydroxide or Ledermix is applied inside the canal and then closed by temporary filling then after 7 days in the second visit canal irrigation and dry then obturation performed by single cone which selecting responding to master apical file. Mark the Visual Analog Scale using to measure the pain by patient as follows; immediate after treatment in the first visit before, after 3 hours, after 24, 48 hours, 7 days and after obturation.
Results and Discussion: Before root canal treatment, after mechanical preparation, 1 day, 2 days, and 7 days of the first visit and immediately after obturation, shows no different in pain value between all groups. After 3 hours of first visit, Ledermix group shows markedly lower pain value in Visual Analog Scale (VAS) score than NaOCl 5.25% group.
Conclusion: With limitation of this study there were slightly different between both groups. There’s no real data to prove that using of ledermix lead to relief the post endodontic pain and still matter of debate and need further study to prove it.
