(2018) Intriago Morales, Ruth Viviana; Ortiz Garay, Elida Magaly; Narvaez Miranda, Deborath Estefania; Vega Yepez, Andres Gustavo; Villavicencio Caparó, Ebingen
Objectives: To compare efﬁ cacy of three irrigation protocols in the removal of calcium hydroxide [Ca(OH)2]. Materials and Methods: Through an in vitro comparative study design, 106 root canals of bovine incisors were instrumented up to a ﬁ le of diameter 60, the roots were fractioned into two halves following the major axis of the tooth and a standardized groove was created 2mm from the apical foramen that was ﬁ lled with a paste of calcium hydroxide, then the halves were reassembled, incubated for 7 days and the irrigation protocols were carried out: passive ultrasonic (PUI), sonic with Endo Activator (EA) and manual dynamic activation (MDA), where 5% sodium hypochlorite (NaOCl) was used as irrigant. A negative and positive control was used. With a stereomicroscope the amount of residue was observed, the images were examined and assigned a score according to the van der Sluis scale, ﬁ nally the data were analyzed with the statistical test of Chi-square. Results: The percentages of efﬁ cacy for PUI, EA and MDA irrigation protocols were 87.5%; 46.9% and 28.1% respectively, the PUI technique was superior to EA and MDA and obtained statistically signiﬁ cant differences (p <0.001). Conclusions: PUI was the most effective method in the removal of Ca(OH)2 from the simulated grooves in the root canals.
Eficacia de diferentes tipos de aguja de irrigación en la remoción de debris en dientes Bovinos
(2017) Ortiz Garay, Elida Magaly; Vega Yépez, Andrés Gustavo
Objective: Compare the efficacy of the open-end needle (Flat) with the notched open-end needle (Notched) and the closed-end needle with lateral ventilation (Side-port) in the removal of debris of the apical third on bovine teeth. Materials and Methods: A transverse in vitro study was performed using 108 bovine teeth which were standardized to a length of 16mm and were apically prepared to a K # 60 file, were longitudinally divided and a groove was created in the apical third of the vestibular segment, which was filled with a mixture of debris and irrigant, the teeth were reassembled and distributed in three groups to be irrigated with 8ml of 5.25% sodium hypochlorite using three types of needles, finally dried with paper points . The teeth were disassembled for observation and take photographs of the grooves under the stereomicroscope at 30x. The evaluation of the effectiveness of debris removal was performed by two blinded and previously calibrated observers looking at the images obtained using the score described by van der Sluis. The tabulation and data analysis was performed in "SPSS vs.20" and the Chi Square test was performed
Eficacia de irrigación de dos sistemas ultrasónicos y dos sónicos en la remoción de debris en dientes bovinos

Introduction: Irrigation is an essential part of debridement as it allows cleaning of the root canal system. Current methods for removing smear layer are sonic and ultrasonic activation. Objective: To compare the effectiveness of irrigation between two ultrasonic and two sonic systems in removing debris in bovine teeth. Materials and methods: An in vitro experimental study was performed using 92 bovine teeth sectioned at 16 mm in length, the samples werewere instrumented with Flexofile k files up to a diameter of #60,The teeth were divided and a groove was prepared in the apical third and filled with dentin remains, the halves were reassembled and 4 groups were formed (n= 23), group 1= ultrasonic irrigation (Newtron), group 2= ultrasonic irrigation (Ultra X), group 3=Sonic Irrigation (Endo Activator)and group 4=Sonic Irrigation (Easydo activator)), each group was irrigated with 8ml ofNaOCl 5.25%, irrigant activation was 3 cycles of 20 seconds each. Result: Statistically significant differences were found between group 1 and group 3 (p-value = 0.045 < 0.05) and between group 1 and group 4 (p-value = 0.004 < 0.05). Significant differences were also found between group 2 and group 4 (p-value = 0.008 < 0.05). Conclusions: Both ultrasonic systems demonstrated greater efficacy in removing debris in bovine teeth compared to sonic systems.
Epoxi resin-based root canal sealers: an integrative literature review
(Universidad de Cuenca, 2022-09-12) Domínguez Ordóñez, Gabriela Soledad; Erazo Guijarro, María José; Ortiz Garay, Elida Magaly
Background Correct obturation of the root canal system is essential for the success of endodontic treatment, which is achieved by means of a core and cement. There are several root canal cements (RCCs) on the market; however, because of their excellent characteristics, epoxy resin-based sealers (ERBSs) have been widely used. Objective The main aim of this review is to analyze and integrate the available information on the different ERBSs. Methods An electronic search was performed in the PubMed and Scopus databases, using as search terms “epoxy resin” AND “root canal treatment”, “epoxy resin” AND “endodontics”. Results In general, the ERBSs have good flow properties, film thickness, solubility, dimensional stability, sealing capacity, and radiopacity; they are also able to adhere to dentin while exhibiting low toxicity and some antibacterial effects. However, their main disadvantage is their lack of bioactivity and biomineralization capability. Conclusion A large number of ERBSs were found to be available on the market and AH Plus keeps being the gold standard RCC. However, information on many of them is limited or non-existent, which could be due to the fact that some of them are relatively new. The latter emphasizes the need for relevant research on the physicochemical and biological properties of some ERBSs, with the aim of supporting their clinical use with sufficient evidence via prospective and long-term studies.
Prevalencia de patología pulpar y periapical en pacientes atendidos en la clínica de Posgrado de Endodoncia de la Facultad de Odontología de la Universidad de Cuenca en el periodo marzo 2019- julio 2023
(Universidad de Cuenca, 2025-09-18) Juca Guamán, Claudia Valeria; Ortiz Garay, Elida Magaly
The aim of this study was to determine the prevalence of pulpal and periapical pathology based on the clinical records of patients treated at the Postgraduate Endodontics Clinic of the Faculty of Dentistry at the University of Cuenca during the period 2019–2023. A cross-sectional, observational, descriptive study was conducted, analyzing 705 clinical records that met previously established inclusion and exclusion criteria. The collected data were processed using frequency and percentage statistical analysis with IBM SPSS Statistics software, version 27.0, and the results were presented through graphs and tables for easier interpretation. The most prevalent pathologies were symptomatic apical periodontitis (69.9%) and previously treated teeth (29.2%) as periapical and pulpal conditions, respectively. A predominance of young adult patients (88.5%) and a higher attendance of female patients (63.3%) were observed. Regarding the type of teeth, molars were the most frequently diagnosed with endodontic pathologies (55.1%). These findings indicate a high prevalence of pulpal and periapical diseases, with a correlation observed between previous endodontic treatments and the presence of apical lesions. Although no significant association was found with sex or age, a statistically significant relationship was identified with the type of tooth involved.
