Microapical surgery management of root resorption in anterior teeth caused by dental trauma: case report

Root resorption (RR) is a common complication of traumatic dental injuries (TDIs), which could result in tooth loss and affect life in severe cases. The management of a traumatized tooth with RR remains a challenge for clinicians. In our presented cases, the impacted teeth had a history of trauma and underwent thorough non-surgical endodontic treatment; however, RR still occurred months later and could be observed through a periapical radiograph. Therefore, root canal therapy was performed under a dental microscope with a quick-setting calcium silicate cement to repair the RR site. After a long follow-up, the affected teeth showed almost complete healing of the periradicular tissues without sign of RR. This report demonstrates that external root absorption is typically a consequence of traumatized teeth. However, to date, there is still no effective method for its treatment. Here, we successfully applied microscopical surgery to the traumatized teeth experiencing root absorption and provided them with a new healing opportunity.

A literature review on complications and management of use sodium hypochlorite in endodontics

The most commonly used irrigant in the field of endodontics is sodium hypochlorite in the procedure of root canal therapy. Although the use of sodium hypochlorite is quite safe but on the other hand when it comes in to direct contact with the soft tissue, it can result in soft tissue injury.

Review of Cracked Tooth Syndrome: Etiology, Diagnosis, Management, and Prevention

Cracked tooth syndrome refers to a series of symptoms caused by cracked teeth. This article reviews the current literature on cracked tooth syndrome from four aspects, etiology, diagnosis, management, and prevention, to provide readers integrated information about this. The article begins with an introduction to the odontiatrogenic factors and then covers the noniatrogenic factors that induce cracked tooth syndrome. While the former discusses inappropriate root canal therapy and improper restorative procedures, the latter covers the topics such as the developmental and functional status of cracked tooth syndrome. This is then followed by the description of common clinical diagnosis methods, the prospects of new technologies, and summaries of current clinical management methods, including immediate management and direct and indirect restoration. In the final section, preventive methods and their importance are proposed, with the aim of educating the common population.

A case report of sub-gingival cervical crown fracture reattachment using fiber post- A 22 months follow up

A 15‐year‐old male presented to the Department of Conservative Dentistry and Endodontics immediately after a facial injury having complain of persistent pain in the teeth and the front upper lips. Upon examination it was revealed trauma of the upper incisors, also injury to the marginal gingiva of the front teeth. Further inspections showed slight laceration of the oral mucosa in the lower labial sulcus. Radiographic examination revealed fracture of crown of maxillary central incisor. The treatment plan which was decided comprised of complete removal of fractured crown followed by root canal therapy and immediate post placement and reattachment of the crown.

Application of Partial Pulpotomy in the Treatment of Chronic Pulpitis Caused by Carious in Mature Permanent Teeth: 3 Year-Follow-Up

Purpose: To observe the clinical effect of partial pulpotomy with I Root Bp Plus in cariously exposed mature permanent teeth. Methods: twenty-three cariously exposed mature permanent teeth were choosen by preoperative clinical signs, pulp dynamic examination and imaging examination. After informed consent, rubber barrier was placed. The tooth decay and the inflamed pulp were removed by round bur. After 5% sodium hypochlorite covered the section until sufficient hemostasis was achieved, I Root Bp Plus was used to tightly cover the pulp with a thickness of about 2mm, resin was filled to repaired the shape of the tooth. The capping pulp was examined by X-ray immediately after operation. Clinical and imaging examinations were performed 12 months and 36 months after treatment. Results: After 3 year, the success rate of partial pulpotomy was 86.96%, which is similar as root cannal therapy. Conclusions: The partial pulptomy for caries exposed mature permanent teeth may be an alternative to root canal therapy, and is more consistent with the current concept of minimally invasive and preservation of vital pulp.

Disinfection of the root canal system: what should the protocol be?

The presence of micro-organisms within the root canal system is the critical aetiological factor in peri-radicular periodontitis. During root canal treatment (RCT) it is imperative that this infection and other organic debris are removed from the root canal system. This is challenging because complex tooth anatomy, the presence of a biofilm and the smear layer complicate the process. There are a number of irrigant chemicals and adjunctive systems available in contemporary endodontic practice that are used to disinfect the root canal system during root canal preparation. This article reviews the available evidence concerning these disinfection methods and concludes by presenting a clinical protocol supported by the literature. CPD/Clinical Relevance: A clinical protocol, supported by the literature, is presented for effective decontamination of the root canal system during root canal therapy.

An unusual case of maxillary permanent 1st molar with two pulp canals with pulp necrosis; diagnosis and endodontic management.

The present case report highlights the need to identify variations in root canal anatomy as a prerequisite for effective nonsurgical root canal therapy planning. As clinicians, we need to develop our observational and clinical abilities as well as amend our understanding of the complexities of the canal anatomy. Reports describing the structure of teeth and pulp canals rarely report the presence of two pulp canals in two permanent upper 1st molars. In this case, it describes the nonsurgical root canal therapy of the upper right 1st permanent molar with two pulp canals, which was confirmed by a cone beam.
