The Rehabilitation of Permanent Teeth with Complicated Crown Fracture by MTA Pulpotomy and Re-Attachment: Case Series Report Study and Literature Review

and functional problems caused by dental trauma.Therefore, to overcome this problem, the choice of the most appropriate and emergency treatment is important.Crown fractures have been reported to constitute 26%-76% of the dental trauma seen in permanent dentition and 0.3%-5% crown-root fractures [9].Complicated crown fractures are injuries involving the enamel, dentine and pulp.CCF's treatment must be applied urgently to protect the vitality of the pulp.The most important a criterion of recovery is protective to the pulp against infection.Because appropriate treatment is to decide, the details of clinical and radiological examinations are important; severity of pulpal, time elapsed after the trauma, the development stage of the tooth [10].In these types of injuries, every attempt should be used to achieve pulpal survival and healing.The direct capping is recommended treatment, if the trauma time is limited to 1 or 2 hours and in minor pulp perforation [3,8].However, if the perforation area is large, or more than 24 hours has elapsed since the trauma, amputation should be preferred as the treatment.10The American Academy of Pediatric Dentistry recommends the use of calcium hydroxide and mineral trioxide agent for these treatments.Zinc oxide eugenol, corticosteroid, calcium hydroxide, hydrophilic resins, resin-modified glass ionomer cements, tricalcium phosphate cement and mineral trioxide agent (MTA) can be used in pulp therapy of permanent dentition [11].These fractures must be treated immediately because they not only harm the teeth but also form psychological effects on the patient and their family.Restoration can be made with various techniques and methods such as porcelain jacket crowns, ceramic restorations, and stainless steel crowns or pinned resin restorations [8,12].Despite great developments in restorative materials in recent years, restorative materials have not been produced which would meet the aesthetic and functional properties of the natural tooth structure.Re-attachment is an economic and conservative AbstractFollowing dental trauma, dental injuries may be seen from cracked enamel to avulsion in the teeth.In this clinical study, are presented restoration of fractured dental fragments after the proper treatment of 5 pediatric patients aged 8, 9, 11, 11, and 11 years who occurred complicated crown fracture and exposure to dental trauma in the anterior group of teeth between 2009 and 2013.In the same session complicated crown fracture in the anterior group of teeth were amputated with mineral trioxide agent (MTA) and it was closed with glass ionomer cement.The restoration was completed by attaching the fractured dental fragment with composite resin.This emergency treatment has special importance.Because complicated crown fractures occurring after dental trauma to the anterior group of teeth can lead to pain and complications of functions, aesthetics and psychological problems.
