Management Of Root Perforation Research Articles

The Management of Root Perforation: A Review of the Literature.

Root canal perforation is defined as an opening or communication of the root to the outer oral tissue that occurs either accidentally during root canal therapy or due to unknown pathological causes, which generally result in complications in patientsdue to the passage of microorganisms to the surrounding tissues. These complications may necessitate extraction of the affected tooth. In this literature review, 42 articles were reviewed initially; 33 of them were included in the final analysis based on exclusion and inclusion criteria. Root perforation may occur due to caries, external and internal resorption, trauma, as well as iatrogenic causes. Many studies have suggested that perforation can be identified by radiographs, unexpected bleeding and pain during instrumentation, blood on paper points, electronic apex locator, and dental operating microscope. Several materials have been used in endodontic perforation repairs, such as indium foil, super 2-ethoxybenzoic acid (super EBA), as well as bioceramic materials like mineral trioxide aggregate (MTA) and biodentine. These materials must achieve biocompatibility, bacteriostatic ability, and radio-opacity. Many studies have reported the superior properties of MTA in comparison with other materials. Based on our literature review, management of root perforation should be performed based on multiple significant factors. Clinicians must possess a comprehensive understanding of tooth anatomy to prevent perforation occurrence. Furthermore, clinical management and prognosis of root perforation have been enhanced by the availability of advanced materials and sealing techniques.

Management of root perforation and sodium hypochlorite extrusion injury

A patient was brought to A&E by their GDP who had injected sodium hypochlorite (NaOCl) through a perforation in the patient's LR4, resulting in pain, swelling and immediate formation of a large, necrotic ulcer. Within 2 days, the patient developed paraesthesia in the distribution of the right mental nerve. Antibiotics and steroids were prescribed to alleviate the acute symptoms. The perforation was repaired with mineral trioxide aggregate (MTA) and root canal treatment was completed with the aid of a microscope. Review appointments were arranged to monitor healing of the injury.CPD/Clinical Relevance: Management of iatrogenic root perforation and associated NaOCl injury is useful knowledge.

MTA-An Elixir for Root Perforations-A Short Review

Root perforations are artificial connections between the root canal system and the periodontium and/or the oral cavity. They are undesired complications of endodontic treatment. It is very important to seal the site of perforation once diagnosed to minimize injury and prevent contamination of the surrounding periodontal attachment apparatus. Mineral trioxide aggregate is an endodontic cement used in treatment of root perforations and it is extremely biocompatible, hydrophilic and capable of stimulating the healing processes. Root perforation is a sign of endodontic failure and is the most common complication of endodontic therapy. The aim of this review is to understand the effectiveness of MTA in management of root perforations and to determine the prognosis of the treatment. Knowing the effectiveness of MTA may fasten the treatment and be more effective compared to other methods.

Management of Root Perforations Using MTA with or without Er:YAG Laser Irradiation: An In Vitro Study

The aim of this in vitro study is to compare the microleakage of a root perforation sealed with MTA (mineral trioxide aggregate) (group M) to that sealed with MTA following Er:YAG laser irradiation (group ML). Forty-two recently extracted human monoroot teeth were used. Two cavities were prepared on each root surface. Randomly, on each root, the exposed dentine of one cavity was irradiated prior to MTA filling using an Er:YAG laser with the following settings: 200 mJ/pulses under an air water spray, 10 Hz, pulse duration of 50 μsec, and 0.7 mm beam diameter. All cavities were then sealed with MTA. submitted to thermocycling and immersed in 2% methylene blue dye solution for 12 h. The penetration of methylene blue in the microleakage of cavity was observed and recorded. The mean value dye penetration in cavities sealed with MTA following Er:YAG laser irradiation (23.91 ± 14.63%) was lower than that of unlased cavities sealed only with MTA (25.17 ± 17.53%). No significant difference was noted. The use of an Er:YAG laser beam for dentinal conditioning prior to MTA filling of perforated roots did not decrease significantly the microleakage of MTA sealing when compared to the conventional use of MTA filling.
