Published online Mar 3. doi: /viajeras.info . Calcium hydroxide (Ca(OH)2) intracanal dressing was found to increase the healing rate in . MDP, Bis-GMA, HEMA, hydrophobic dimethacrylate, . To date, no study has evaluated the effect of NaOCl/Glyde irrigation protocol on the bond strength to dentin.

Several techniques have been used to detect MB2 canals in maxillary molars in both in vitro and clinical studies, including operating microscopes 6 - 11ultrasounds 12the use of a bur and explorer 1013and conventional or advanced radiographic techniques 14 - Such approaches are commonly used to facilitate the detection of MB2 canals 101920 ; however, the abovementioned methods cannot reliably detect MB2 canals Cone beam computed tomography CBCT is a new technology in the field of endodontics that has several advantages, including the ability to perform three-dimensional 3D imaging of root canal systems with lower radiation doses, higher resolution, and no superimposition 26 - Therefore, CBCT could be useful for several common endodontic fields, including endodontic surgery, dental trauma, internal or external root resorption, diagnosis of apical pathosis, and evaluation of the complex root canal configuration 29 - However, few studies with sufficient and satisfactory findings regarding the localization of MB2 canals using CBCT could be found in the literature.

Therefore, the aim of the present in vitro study is to develop a new approach for localizing MB2 canals in the maxillary first molars using CBCT.

This method could facilitate the detection of MB2 canals in clinical practice. Patients and Methods This retrospective study included CBCT data from patients who were referred to the department of dentomaxillofacial radiology, faculty of dentistry, Gaziantep, Turkey, from to The CBCT data were recorded for several reasons, including implant surgery, pathological reasons, or orthodontic treatment.

A total of maxillary first molars were investigated from patients males and females with a mean age of Maxillary first molar teeth with no caries or defects, filled materials, periapical lesions, root canal treatments, or root canals with open apices, resorption, or calcification were evaluated to prove that reliable, good quality CBCT images were available.

Any cases of the abovementioned conditions were excluded from the study since they may adversely affect the image quality. The study was approved by the local ethics committee of the university of Gaziantep. All of the images from maxillary molar teeth were evaluated on the axial section.

Using the axial section as a guide allowed the accurate localization of the designated parameters without superimposition in different planes. Thus, the reproducibility of the measurements was ensured by the use of such standardization The first axial section where the angles formed by the canal orifices were seen from the axial plane was used to determine the angles used in the present study.

In fact, there was no final decision on this matter in the literature. The following parameters were recorded: Adhesion to coronal dentin is dependent upon the irrigation regimen and the type of adhesive.

Bond strength to coronal dentin, NaOCl, Glyde-File-Prep, Ca OH 2 Introduction One of the primary goals of root canal treatment is to eliminate bacteria from the root canal system, which have been shown to be the etiology for apical periodontitis and endodontic failure.

Furthermore, restoring of the tooth after root canal treatment should be capable of preventing recontamination of the root canal system [1].

However, endodontic materials inevitably contact the dentin of the access cavity during chemomechanical root canal preparation, therefore the dentin available for the coronal restoration may be modified and bonding procedures may also be affected [3—8].

Sodium hypochlorite NaOCL 5. However, it has been reported that it induces oxidations of some components in the dentin matrix [4,5] and also causes dentin subsurface deproteinization [10]. In literature, NaOCl irrigant was found to decrease the bond strengths of some adhesive systems [3—6] that was recovered by using reducing agents as sodium ascorbate [4,5]whereas it did not affect [3,5,7] or even increased [8] the bond strengths of other adhesives to coronal dentin.

The strategy of alternating irrigation with NaOCl and Ethylenediaminetetraacetic acid EDTA was found to maximize the effectiveness of the antisepsis, due to effective removal of the smear layer and increased dentin permeability [11,12]. It is claimed to facilitate endodontic shaping and cleansing due to the chelating EDTA and the effervescence through H2O2.

It has been well reported that sodium perborate SP ; a H2O2-releasing agent used intra-coronally for tooth bleaching, reduces the bond strength of resin to coronal dentin [14]. The use of chlorhexidine CHX as a final rinse was found to enhance the disinfection of the root canal system [9,15]. In addition, encouraging recent studies [16,17] have demonstrated that the application of CHX to dentin decelerated the degradation of the hybrid layer exposed collagen fibrils.

CHX was found not to produce detrimental effects to the immediate bond strength [16,17].

However, higher concentrations decreased the bond strength of some adhesive systems [18].
