introduction : root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. the present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (cem) cement. materials and methods: a prospective outcome study of periradicular surgery using cem was conducted on 14 p...

INTRODUCTION The purpose of this ex vivo study was to assess the effect of two root-end filling materials against Candida (C) Albicans. MATERIALS AND METHODS ProRoot MTA and CEM Cement were compared immediately and 24 h after mixing, in two different concentrations (50 and 100 mg/mL). A total of 50 culture wells were used and divided into experimental (n=10) and control groups (n=5). Those wi...

severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. this article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. the tooth had a history of tra...

Introduction: Sealing ability of a retrograde filling material is an important factor for a successful endodontic apicoectomy. The purpose of this in-vitro study was to compare the sealing ability of calcium enriched mixture (CEM) cement versus amalgam as root-end filling materials. Methods: A total of 36 canals of extracted maxillary central incisors were instrumented and obturated using later...

Iatrogenic perforation of the furcation area in multi-rooted molars during preparation of the access cavity can potentially lead to tooth extraction. The present case report describes the nonsurgical endodontic management of an extensive pulp chamber floor perforation in a first mandibular molar with calcium enriched mixture (CEM) cement. The perforation was chemically cleaned and then physical...

For management of a symptomatic maxillary lateral incisor with dull pain on chewing, suppurative sinus tract, defective metal-ceramic crown and iatrogenic internal root resorption, an interdisciplinary approach was taken. Two-visit nonsurgical treatment with calcium-enriched mixture (CEM) cement, replacement of metal-ceramic crown with all-ceramic crown and corrective periodontal plastic surger...

abstract statement of problem: the ph of the human abscess has been measured as low as 5.0. this low ph could potentially inhibit setting reactions, affect adhesion, or increase the solubility of root end filling materials hence affect the compressive strength. moreover, root end filling materials might expose or even mix with lidocaine hcl during periapical surgery. objectives: the aim of this...

INTRODUCTION This case report describes apexogenesis treatment of three molar teeth of an 8-year-old boy using three different pulpotomy agents. METHODS Pulpotomy was performed on decayed immature molar teeth with established irreversible pulpitis and the remaining pulp was capped with either zinc oxide eugenol, ProRoot mineral trioxide aggregate or calcium-enriched mixture (CEM) cement. Teet...
