Distribution of sodium hypochlorite throughout the mesial root canal system of mandibular molars after adjunctive irrigant activation procedures: a micro-computed tomographic study

Background: Enhancement of the temperature of sodium hypochlorite (NaOCl) solution would increase its cleaning potential and decontamination of the root canal system. Therefore, the aim of the present in vitro investigation was to compare the efficacy of different methods of NaOCl heating by evaluating the temperature profiles developed at different levels of the root canal system. Methods: Five thermocouples were applied at different levels of the root canal system of extracted human premolars. NaOCl solution was heated according to two methods: extraoral heating (50 °C, 60 °C, and 70 °C) using a magnetic hotplate heater and intracanal heating by F-06, XF-30/04, and ML-12 pluggers at 100 °C, 150 °C, and 180 °C. Results: The extraoral heating method was ineffective to produce a significant temperature increase at the root apex. Comparable results were obtained using the intracanal heating method through the ML-12 plugger that showed slightly better results only when set at 180 °C. On the other hand, negligible differences were observed in terms of temperature maintenance at several levels of the root between the F-06 and XF-30/04 pluggers, even though the time intervals were higher in case of XF-30/04. Conclusions: The intracanal heating method provided a better temperature persistence in the middle third of the root canal system. Conversely, extraoral heating was ineffective to produce a significant temperature increase at the apex of the root. Comparable results were obtained even using the ML-12 plugger.

Root Canal System

The success of endodontic treatment depends on many factors. The most important of them are the knowledge and manual skills of the dentist.Materials and methods. We analyzed the condition of teeth after endodontic treatment in 300 patients aged 20 to 70 years. Were studied 300 images of CBCT, the number of treated teeth and the number of cases of unsuccessful endodontic treatment was analyzed.Results. According to CBCT data, high-quality obturation of the root canal system was observed in 1335 (75%) endodontically treated teeth. The reasons for successful endodontic treatment are under-sealing of the root canal (16%), removal of material beyond the apex (5.6%), and missed root canals (3.4%).Conclusion. Clinical dental patient examination revealed that maxillary and mandibular molars most often undergo endodontic treatment.

Pulp Stones

ABSTRACT Pulp stones are nodular, calcified masses commonly appearing in the coronal pulp and occasionally extending in radicular pulp. Retrieval of pulp stones remains a challenge for the endodontist as complete cleaning and shaping of root canal system is the bases for successful endodontic therapy. The aim of this case report is to show the retrieval of long pulp stones measuring 14 and 9.5 mm by utilizing synergistic effect of ultrasonics and sodium hypochlorite from the palatal roots of maxillary molars. Such case has not been reported in the literature so far. How to cite this article Nanjannawar GS, Vagarali H, Nanjannawar LG, Prathasarathy B, Patil A, Bhandi S.

Removal of vital and necrotic remnants of pulp tissues, microorganisms, and microbial toxins from the root canal system is warranted for ensuing successful treatment outcome. Irrigation plays a major role in achieving the same. The last few years have seen a spurt in technological advances in various irrigant activation devices. This article meticulously reviews the various irrigant agitation systems available, which assists in complete disinfection of the complex root canal system.
