Bacterial Disinfection

Theoretical simulations of temperature elevations in root dentin are performed to evaluate, how heating protocols affect the efficacy of using erbium, chromium; yttrium, scandium, gallium, garnet (Er,Cr;YSGG) pulsed lasers for bacterial disinfection during root canal treatments. The theoretical models are generated based on microcomputer tomography (microCT) scans of extracted human teeth. Heat transfer simulations are performed using the Pennes bioheat equation to determine temperature distributions in tooth roots and surrounding tissue during 500 mW pulsed Er,Cr;YSGG laser irradiation on the root canal for eradicating bacteria. The study not only determines the heat penetration within the deep dentin but also assesses potential thermal damage to the surrounding tissues. Thermal damage is assumed to occur when the tissue is subject to a temperature above at least 47 °C for a minimum duration of 10 s. Treatment protocols are identified for three representative tooth root sizes that are capable of maintaining elevated temperatures in deep dentin necessary to eradicate bacteria, while minimizing potential for collateral thermal tissue damage at the outer root surfaces. We believe that the study not only provides realistic laser heating protocols for various tooth root geometries but also demonstrates utility of theoretical simulations for designing individualized treatments in the future.

The main criterion for successful endodontic treatment is thorough cleaning of the root canal from microorganisms. Modern technologies are being developed to decontaminate the root canal system due to local temperature increase. High-frequency monopolar diathermocoagulation refers to one of these technologies. Aim. To determine the optimal parameters of monopolar high-frequency diathermocoagulation providing a distinct antibacterial effect and which are safe for the surrounding tissues in endodontic dental treatment. Materials and methods. Root canals of single-root removed teeth from the group of upper and lower jaw incisors (12 samples). The DC-35 MS device (2640 kHz, 1. 5 kOhm) was used to study various modes of high-frequency monopolar diathermocoagulation. 6 exposure modes were studied. To determine the heating degree of the tooth root surface, thermometry using a compact infrared radiation converter of the Seek Thermal imager was used, and a remote infrared thermometer Testo 830-T1 was used for temperature monitoring. After determining of the diathermocoagulation modes that are not able to cause significant heating of the surrounding tooth tissues, the antibacterial effect of diathermocoagulation in these modes was studied. To do this, we used clinical strains of optionally anaerobic bacteria obtained from the teeth root canals in pulpitis: Streptococcus sanguis, Streptococcus mutans, Enterococcus faecalis, Escherichia coli and yeast-like fungi Candida albicans. Results. When performing diathermocoagulation of the root canal contents, the third, fourth and sixth modes of the device settings with the power given to the tissue within three seconds of energy in the range of 3.06 W to 5.4 W are safe for the tissues surrounding the tooth root. When treating root canals in the third and sixth modes, the power of diathermocoagulation is 5.4 W and 4.1 W. A multiple, significant decrease in microbial contamination of root canals by all kinds of pathogenic optional anaerobic microflora obtained from the teeth root canals in pulpitis was found.

A post-and-core crown is widely used in prosthetic dentistry; however, in clinical treatment, it easily causes root fracture and tooth penetration. To address these problems, this study aimed to present a customized post-and-core design for the posterior tooth implant. First, a residual tooth and its root canal were reconstructed. Then, the root canal surface was extracted, the surface curvature and length parameters were defined, and the customized post-and-core design was developed. Finally, the tooth, root canal, and post-and-core with different implant lengths in five masticatory directions were analyzed using finite element analysis to evaluate the stress distribution. The results showed that, with the similar shape of the post-and-core structure and the root canal, the tooth stress trend was uniform. When the length of the post-and-core structure [Formula: see text] was 0[Formula: see text]mm, that is, it was two thirds of the root canal length, the root canal stress was minimum. Therefore, the customized design of the post-and-core structure could well adapt to any kind of root canal, and the length of the post-and-core structure [Formula: see text] provided guidance for the post-and-core crown prosthesis in clinic.

The aim: To establish the dynamics of reparation processes in periapical tissues in chronic granulomatous periodontitis under the influence of the developed composition based on calcium hydroxyapatite in comparison with the generally accepted drug MTA. Materials and methods: The main group included 52 individuals, and the comparison group – 19 patients with chronic granulomatous periodontitis. In the first experimental subgroup, patients were obturated of the tooth root apical area with the proposed composition, and in the second experimental subgroup patients were performed obturation of the root canal apical area with additional transcanal withdrawal of the composition into the periapical area. In the comparison group, the tooth root apex was obturated with MTA material. Results: Clinical studies have shown that the composition based on calcium hydroxyapatite, having osteoconductive, antioxidant and anti-inflammatory properties, activates the synthesis of organic and mineral components, that promotes the bioreparation and regeneration processes of periapical tissues in chronic granulomatous periodontitis, which occurred most intensively during the first 6 months after treatment. At the same time, with additional transcanal removal of the filling composition based on calcium hydroxyapatite into the periapical area in patients with chronic granulomatous periodontitis with acquired wide tooth root apex was observed in 1.6 time better results than the method of creating an apical root canal obturation (p <0,05), indicating a high therapeutic effect. Conclusions: Composition based on calcium hydroxyapatite, having osteoconductive, antioxidant and anti-inflammatory properties, activates the synthesis of organic and mineral components, which promotes the processes of bioreparation and regeneration of periapical tissues, especially in the early stages. And additional transcanal removal of the filling composition into the periapical space causes the acceleration of the period of periodontal tissues revitalization, bioreparation and regeneration compared to the creation of the apical obturation within the physiological tooth root apex.

Feasible Option

Coronal fractures of the anterior teeth are common sequelae of dental trauma. In case of complex fractures, where the fractured segment is available and there is close approximation of the segment to the remaining tooth, root canal treatment followed by reattachment of the fractured segment with fiber post reinforcement is a feasible option. The procedure is simple and economic and needs less chair-side time as compared to many conventional methods. In addition, the procedure provides good and long-lasting esthetics, because the original morphology, color, and surface texture are maintained. This paper reports three cases of complex coronal tooth fracture successfully managed using tooth fragment reattachment.

Canal Shaping

Pathological resorptions of a tooth root very often represent both a diagnostic and therapeutical problem. The goal of this study was, based on clinical research on a number of pathological resorptions of various types and localization in relation to time, to analyze and evaluate applied endodontic therapy. Clinical research covered 30 patients (40 root canals in total). 18 teeth (22 canal) with external and 12 (18 canal) with internal root resorptions received endodontic therapy. After standard endodontic procedure had been applied (cleaning and canal shaping) calcium hydroxide paste was used as a canal medicament for cases with internal resorptions and calcium hydroxide paste and points for cases with external resorptions. Canal opturations were done by modified technique of lateral condesation applying AH- Plus paste. The obtained results showed that in cases of internal resorption after 12 months, 11 cases were successful and only 1 failure occurred. In case of external resorption, after the same period of time, 15 cases were successful and failures occurred in 3 cases. The success of resorption treatment depends on many factors but, primarily, it depends on time and accuracy of diagnosis and properly applied treatment and root canal opturation.
