Brazilian science has gained significant ground on the international stage in recent decades. Researchers, universities, and graduate programs have come to occupy prominent positions in various fields of knowledge in international rankings. However, in this process of internationalization, we may have overlooked an equally important question: what is the role of national scientific journals in the construction and consolidation of our own science? The search for high-impact international...

INTRODUCTION: Radiographic follow-up is a fundamental mechanism to determine the success of endodontic treatment, enabling the evaluation of the periapical healing process and the early identification of potential signs of failure. OBJECTIVE: This study aimed to analyze the importance of radiographic follow-up in evaluating endodontic treatment success. METHODS: This is an integrative literature review conducted through searches in the Google Scholar, SciELO, PubMed, and Scopus databases,...

INTRODUCTION: Apical extrusion and the persistence of intracanal microorganisms are associated with postoperative pain and endodontic treatment failure. Ultrasonic inserts increase the surface area of the canal walls contacted during instrumentation; however, whether this increased contact reduces the microbial load remains unclear. OBJECTIVE: This study evaluated whether ultrasonic complementation of the cervical and middle thirds, prior to apical preparation, reduces microbial extrusion and...

INTRODUCTION: Dens invaginatus is a developmental anomaly with substantial anatomical variability that may facilitate early infection and complicate diagnosis and treatment. OBJECTIVE: To report the diagnosis and nonsurgical endodontic treatment of type IIIA dens invaginatus associated with an extensive periradicular lesion in an adolescent, emphasizing the contribution of cone-beam computed tomography and the CARES system. CASE REPORT: A 15-year-old female patient presented with a recurrent...

INTRODUCTION: Endodontic treatment of teeth with C-shaped canal anatomy is challenging due to the complexity of the root canal system, including isthmuses, recesses, and communications that may compromise cleaning, shaping, and obturation procedures. OBJECTIVE: This study reports the endodontic management of a mandibular molar with a C-shaped canal configuration. CASE REPORT: A 37-year-old male patient was referred for endodontic treatment of tooth #37 after emergency management of symptomatic...

OBJECTIVE: To evaluate the effect of glide path preparation and coronal pre-flaring on canal length changes and instrument fracture incidence in simulated double-curved root canals. METHODS: Sixty resin blocks with double-curved canals were randomized into four groups (n=15): GV) #2 Gates-Glidden bur + V-file V25; V) V-file V25 alone; TV) T-file glide path + V-file V25; and GTV) #2 Gates-Glidden bur + T-file + V-file V25. Canal length was measured before and after preparation using a #08...

OBJECTIVE: This study compared the perception and acceptance of undergraduate and postgraduate dental students from Piracicaba Dental School (FOP/UNICAMP, Brazil) regarding the use of manual and mechanized nickel- titanium (NiTi) endodontic instruments. METHODS: Eighteen undergraduate students and one postgraduate student participated in the study. All participants had previous training in manual instrumentation with stainless steel files (SSF) and were subsequently trained in the use of...

INTRODUCTION: Reciproc® Minima is a reduced-taper reciprocating nickel-titanium system developed to promote conservative root canal shaping while maintaining the simplified instrumentation philosophy of the Reciproc® family. OBJECTIVE: This article presents the design characteristics of the system, discusses its clinical rationale, and illustrates its application through four representative clinical cases involving anatomically challenging root canals. RESULTS: In all cases, instrumentation...
