Successful endodontic treatment relies upon a thorough knowledge of root canal anatomical variations along with proper diagnosis, treatment planning, and clinical expertise. One of the difficult root canal configurations that are frequently encountered commonly in mandibular second molars is C-shaped root canal. Due to the intricate root canal configuration, it is often difficult to negotiate, debride, and obturate such canals leading to failure of root canal treatment. Understanding the anatomical variation and adequate visualization will enable the clinician to manage these cases effectively...

AIM: The aim of this study was to assess and compare the influence of the presence of full-coverage crown on the obturation material removal efficiency of different retreatment file systems. MATERIALS AND METHODS: Sixty extracted, human, maxillary premolars were accessed, instrumented, and obturated with gutta-percha and AH Plus sealer. The samples were scanned with cone-beam computed tomography and volume of obturating material was measured using ITK-SNAP volumetric software...

BACKGROUND: Cavity preparation often causes gingival bleeding which can be controlled by hemostatic agents (HAs). These along with blood act as contaminants and hamper the bonding mechanism. Collagen cross-linkers (CCLs) are agents known to increase the bond strength (BS) to dentin. Hence, the purpose of this in vitro study was to determine the effect of two different CCLs, proanthocyanidin (grape seed extract [GSE]) and hesperidin on the microtensile BS (μTBS) of a self-etch adhesive (SEA) system to dentin which was contaminated with blood and a HA...

INTRODUCTION: The study evaluates and compare the effect of 3% warm NaOCl with NaOCl at room temperature in root canal irrigation on postoperative pain. MATERIALS AND METHODS: In this randomized controlled trial, mandibular molars with symptomatic irreversible pulpitis in healthy 18-year-old patients and above were included. The sample consisted of 56 patients evaluating the postoperative pain, allocated randomly into 2 groups of 3% NaOCl at two different temperatures, i...

AIM: Assessment of remineralizing agent's effect on laser and nonlaser bleached enamel surfaces subjected to erosion. MATERIALS AND METHODS: In this study, 80 extracted human permanent anteriors were collected and divided into 4 groups with 20 teeth per sample. Enamel specimen of 3 mm × 3 mm were made using polyvinyl chloride rings and acrylic and randomly divided into four groups. Then the specimens were subjected to initial microhardness test using Vicker's hardness tester (AVK-CO, Mitutoyo, Japan)...

AIM: The aim of this study was to assess and compare the effect of ultrasonic and diode laser-activated sodium hypochlorite (NaOCl), chitosan, and chlorhexidine (CHX) on the removal of Enterococcus faecalis biofilm adherent to the root canal using a confocal laser scanning microscope (CLSM). MATERIALS AND METHODS: Root canals in 112 single-rooted teeth were instrumented using a rotary Ni-Ti system. Biofilms of E. faecalis were generated based on an established protocol...

CONTEXT: Adjuvant use of platelet-rich fibrin (PRF) in many areas of dentistry is well documented. However, its role in periapical surgery remains contested which requires further clarification by a higher level of evidence. AIM: The objective of this systematic review was to evaluate the effect of PRF on periapical surgery using meta-analysis. MATERIALS AND METHODS: A comprehensive literature search was conducted in PUBMED, Cochrane Central Register of Controlled Trials, SCIENCE DIRECT, and GOOGLE SCHOLAR for randomized controlled trials (RCT) published until May 2021...

BACKGROUND: Dental bleaching is not recommended on teeth with enamel caries. AIM: The study aimed to assess the efficacy of in-office bleaching on demineralized enamel managed by resin infiltration (RI) as well as casein phosphopeptide-amorphous calcium phosphate (CPP-ACP). METHODOLOGY: Forty-eight sound enamel specimens were divided into four groups based on the surface treatment performed before in-office bleaching. Group I consisted of no caries and no treatment (NT); Group II had artificial caries (AC) and NT; Group III had AC treated with RI, and Group IV had AC remineralized with CPP-ACP...

AIM: The aim of this in vitro study was to measure the quality of marginal adaptation of three root end filling materials by scanning electron microscope (SEM). METHODOLOGY: Thirty extracted human permanent single-rooted single canal maxillary anterior teeth with mature apices were prepared up to 60 K-file and obturated. Teeth were resected 3 mm from the apex using a cross-cut fissure bur at 90° angle to the long axis of the tooth. Root end cavities of 3 mm were prepared in each of the teeth with an ultrasonic tip to receive the root end filling material...

BACKGROUND: Cleaning and shaping represent a vital step in the endodontic procedure. In routine endodontic therapy, the fracture of nickel-titanium (NiTi) instruments is a procedural problem creating a major obstacle to therapy. AIM: This study examines the life span of one Neoendo Flex and ProTaper Next (PTN) rotary file using reciprocating motion and compares the time required by both file systems for canal preparation. MATERIALS AND METHODS: One hundred maxillary permanent central incisors were selected...

OBJECTIVE: The objective of the study was to evaluate the effect of access cavity design on fracture resistance of the extracted maxillary first and second molars prepared with three minimally invasive files. MATERIALS AND METHODS: One hundred and twelve extracted human maxillary molars were selected for the study and divided randomly into three groups according to different minimally invasive files used (self-adjusting files [SAF], XP-endo Shaper [XP], and 4 V-Taper 2H [VT]) and one control group (CG)...

A concomitant complicated crown-root fracture (CCRF) and horizontal root fracture (HRF) is rarely reported in literature. This report proposes a two-staged single-visit treatment to salvage maxillary central incisor with coexisting CCRF and HRF. A female patient with CCRF with additional HRF (AHRF) of maxillary left central incisor was successfully managed with a novel two-staged treatment strategy. Stage 1 included stabilization of AHRF followed by fragment reattachment in Stage 2 of the treatment. At 5 years of followup, clinical examinations revealed no mobility or discoloration of the reattached fragment with satisfactory periodontal condition...

OBJECTIVE: This study evaluates the effects of immediate dentin sealing (IDS) on the fracture resistance of lithium disilicate overlays using three different types of resin-luting agents (preheated composite, dual-cure adhesive resin, and flowable composite). MATERIALS AND METHODS: Forty-eight maxillary first premolars of equal size were prepared using a butt joint preparation design. The teeth were separated into two primary groups, each with 24 teeth: Group DDS - delay dentin sealing (DDS) (non-IDS) teeth were not treated...

AIM: The aim of this study was to evaluate the effectiveness of ultrasonic activation of ethylenediaminetetraacetic acid (EDTA), maleic acid (MA), and fumaric acid (FA) in combination with sodium hypochlorite (NaOCl) on postendodontic treatment root fracture toughness. MATERIALS AND METHODS: Forty single-rooted mandibular premolars were sectioned below the cementoenamel junction and were kept on average 14 mm long. With the exception of eight randomly selected teeth acting as a negative control group (Group I/nonprepared), the rest were prepared till F3...
