Differences in cyclic fatigue resistance between ProTaper next and ProTaper universal instruments at different levels
(Elsevier, 2014) Perez-Higueras, Juan José; Arias Paniagua, Ana María; Macorra García, José Carlos de la; Peters, Ove A.
Introduction: New designs and alloys have been developed toincrease cyclic fatigue (CF) resistance of rotary files. the aim of this study was to compare CF resistance of ProTaper Universal (PTU) ; Dentsply Tulsa Dental, Tulsa, OK) and ProTaper Next (PTN, Dentsply Tulsa Dental) instruments at different points of curvature. Methods: A total of 420 files (240 PTU, S1, F1, f2 and F3 and 180 PTN, X1, X2 and X3) were divided in 14 groups of 30 instruments each. Instruments in groups s1-5, F1-5, X1-5, F2-5, x2-5, F3-5, and X3-5 were tested at 5 mm from the tip. groups F2-8, X2-8, F3-8 and X3-8 were tested at 8 mm (F2/X2 and F3/X3, respectively, had the same diameter at 8 mm). All files were rotated at 300 rpm until fracture. CF resistance was tested in stainless steel curved canals (60º, r=3 mm). Time to fracture was recorded. The mean half-life and beta and eta were calculated for each group and were compared with Weibull analysis. Results: PTN instruments will last significantly longer than PTU files with a probability higher than 98% at all tested levels except for S1, which was the significantly more resistant instrument to CF at 5 mm from the tip. Conclusions: PTU S1 was significantly the most resistant instrument at 5 mm from the tip. PTN files were significantly more resistant to CF than PTU instruments at all the other tested levels.
Prospective case controlled clinical study of post-endodontic pain after rotary root canal preparation performed by a single operator
(Elsevier, 2015) Arias Paniagua, Ana María; Macorra García, José Carlos de la; Azabal, Magdalena; Hidalgo Arroquia, Juan José; Peters, Ove A.
Objectives: The aim of this study was to asses the influence of the shaping technique on incidence, intensity, duration and type of postoperative pain (PP). Methods: Root canal treatments were carried out with rtary instrumentation (n=80) during a single-visit, and data about pre-treatment conditions were collected. Patients were given a questionnaire to record the presence or absence of post-endodontic pain, its duration and level of discomfort. A matching patient (same pre-treatment conditions but manual instrumentation) was randomly selected from a pool (n=374) and assigned to the control group. A total of 44 pairs of patients matched completely and were included in the study. Incidence (yes/no) of PP was assessed using Chi-square tests, intensity (mild, moderate, severe) with trend tests and duration (days) with Mann-Whitney U tests. Results: A significantly greater proportion of the patients in the control group reported pain than did patients in the rotatory shaping group (p<0.05). However, pain duration was shorter (p=0.008) in the control group. Differences in level of discomfort were not statistically significant. Conclusions: The results of this prospective in vivo study suggest that a higher incidence of PP should be expected after manual root canal preparation. However a second major finding of the study is that when present, PP after a rotatory canal preparation is expected to last longer. Clinical significance: There has been an increase in the use of rotatory techniques among dentists in recent years. The present study analyses the differences in the incidence and characteristics of postoperative pain that should be expected after rotary canal preparation compared to traditional manual methods that had not been reported yet.

(MDPI, 2020-07-07) Bamini, Lavanya; Sherwood, Anand; Arias Paniagua, Ana María; Subramani, Savadamoorthi Kamatchi; Bhargavi, Puridi
The objective of this prospective study was to assess tooth-related factors that play a role in the incidence of postoperative pain (PP) and determining if procedural errors influence PP occurrence. A total of 442 patients referred for root canal treatment met the inclusion criteria and were included in this prospective study. The same protocol was used in all root canal treatments. Patient, tooth, treatment related factors and the occurrence of procedural errors were registered. Incidence and intensity of PP was assessed at 24 and 48 h by telephonic interview and in person seven and 15 days after treatment. A logistic and ordinal regression analysis was used to assess the role of patient, tooth and treatment related factors in the incidence and intensity of PP, respectively. Preoperative and intraoperative factors differently affected the incidence of PP at the different time intervals. The presence of procedural errors did not significantly influence PP occurrence. The presence of preoperative pain and the need of additional anesthesia during treatment were associated with higher incidence of PP 24 and 48 h after treatment; the extent of apical enlargement played a significant role in the presence of PP after seven days of treatment; and the excessive occlusal load induced by the absence of a contralateral tooth was the only factor related to the maintenance of PP up to 15 days. In conclusion, the presence of preoperative pain, the need of additional anesthesia during treatment, the extent of apical enlargement and the excessive occlusal load induced by the absence of a contralateral tooth were related to a higher incidence of PP.
Manual de manejo del microscopio operatorio en prácticas clínicas
(2022) Arias Paniagua, Ana María; Gancedo Caravia, Lucía; Pérez-Higueras Sánchez-Escalonilla, Juan José
El microscopio operatorio es una herramienta de magnificación empleada en muchos campos de la Medicina y especialmente útil para la práctica clínica odontológica. Permite una visión aumentada e iluminada del campo operatorio lo que posibilita la ejecución de tratamientos más precisos y conservadores. El empleo de magnificación está muy extendido en profesiones que requieren destreza manual y precisión. En odontología, las lupas y los microscopios quirúrgicos se han convertido en parte del equipamiento clínico habitual gracias a que mejora la agudeza visual y ayudan a compensar deficiencias visuales. (1, 2) Los sistemas de magnificación son útiles tanto para operadores experimentados como para aquellos con menos años de ejercicio ya que permiten mejorar significativamente la agudeza visual independientemente de la edad de los usuarios (3,4). Diferentes trabajos publicados muestran cómo la precisión y calidad de diferentes procedimientos dentales realizados con ayuda de magnificación son superiores al compararlos con aquellos que se realizan a simple vista. (4-7) Además, otra gran ventaja de la incorporación del microscopio operatorio en la práctica clínica es que permite una mejor ergonomía del operador. (2, 8-10) Por otro lado, la incorporación del microscopio operatorio requiere una curva de aprendizaje (10). Este documento pretende servir de ayuda durante el periodo de adaptación para familiarizarse con los ajustes y las características técnicas del sistema. Si bien el uso de un sistema de magnificación puede implementarse en cualquier momento de la carrera profesional independientemente de la experiencia del operador, parece razonable introducir estas herramientas durante la fase de formación pre-graduada para conseguir la adquisición de competencias en el uso de esta herramienta de forma temprana y que el estudiante pueda aprovechar cuanto antes los beneficios de un sistema de aumento, tanto en términos de postura como de mejora en la precisión y calidad de sus trabajos (9).
Estudio prospectivo y predictivo de la sensación dolorosa posterior al tratamiento completo de conductos radiculares
(Universidad Complutense de Madrid, 2004-07-09) Arias Paniagua, Ana María; Azabal Arroyo, Magdalena; Hidalgo Arroquia, Juan José
El dolor postoperatorio es relativamente frecuente tras realizar un tratamiento de conductos radiculares. El objetivo de esta tesis doctoral es determinar si existe alguna relación entre la incidencia, intensidad, tipo y duración del dolor postendodoncia y determinados factores, algunos de los cuales puede controlar el profesional y otros que no puede controlar, que son las condiciones del propio paciente y del diente a tratar. Para ello, un solo operador, especialista en endodoncia, realiza tratamientos de conductos a 500 pacientes en una sola cita. Todos los tratamientos fueron realizados mediante instrumentación manual, condensación lateral y manteniendo la permeabilidad apical de los conductos radiculares durante los procedimientos de limpieza y conformación de los mismos. Mediante el método de medición escala descriptiva simple recogemos la sensación dolorosa postoperatoria experimentada por los pacientes y analizamos los datos obtenidos mediante los estudios estadísticos de Chi cuadrado, estadísco exacto de Fisher y obtenemos modelos predictivos, mediante un análisis de regresión logística, que nos permiten predecir la probabilidad de la incidencia, intensidad y duración del dolor postendodoncia. Encontramos que el grupo dentario, la presencia de dolor previo, la existencia de imágenes radiolúcidas periapicales, la realización de aperturas de urgencia previas y la oclusión son factores predictores de la incidencia de dolor postendodoncia; la arcada dentaria y la edad, de la intensidad; y la presencia de imágenes radiolúcidas, el sexo y la edad, de la duración del mismo.
Predictive models of pain following root canal treatment: A prospective clinical study
(Wiley, 2013) Arias Paniagua, Ana María; de la Macorra, José C; Hidalgo Arroquia, Juan José; Azabal Arroyo, Magdalena
Aim To determine the probability of the incidence, intensity, duration and triggering of postendodontic pain, considering factors related to the patient (age, gender, medical evaluation) and to the affected tooth (group, location, number of canals, pulp vitality, preoperative pain, periapical radiolucencies, previous emergency access, presence of occlusal contacts with antagonist). Methodology A total of 500 one-visit root-canal treatments (RCTs) were performed to patients referred to an endodontist. Shaping of root canals was performed manually with Gates-Glidden drills and K-Flexofiles, and apical patency was maintained with a size 10 file. A 5% NaOCl solution was used for irrigation, and canals were filled with lateral compaction and AH-plus sealer. Independent factors were recorded during the treatment, and characteristics of postendodontic pain (incidence, intensity, type and duration) were later surveyed through questionnaires. Out of the 500 questionnaires, 374 were properly returned and split in two groups for two different statistical purposes: 316 cases were used to adjust the logistic regression models to predict each characteristic of postendodontic pain using predictive factors, and the remaining 58 cases were used to test the validity of each model. Results The predictive models showed that the incidence of postendodontic pain was significantly lower when the treated tooth was not a molar (p=0.003), demonstrated periapical radiolucencies (p=0.003), there was no history of previous pain (p=0.006) or emergency endodontic treatment (p=0.045) and there was no occlusal contact (p<0.0001). The probability of experiencing moderate or severe pain was higher with increasing age (p=0.09) and in mandibular teeth (p=0.045). The probability of pain lasting more than two days was increased with age (p=0.1) and decreased in males (p=0.007) and when a radiolucent lesion was present in radiograph (p=0.1). Conclusions Predictive formulae for the incidence, the intensity and the duration of postendodontic pain were generated and validated considering the interrelation of multiple concomitant clinical factors. A predictive model for triggering postendodontic pain could not be established.
Influence of clinical usage of GT and GTX files on cyclic fatigue resistance
(Wiley, 2013) Arias Paniagua, Ana María; Perez-Higueras, Juan José; de la Macorra, José Carlos
Aim To compare static cyclic fatigue resistance of unused, unused and sterilized and clinically used conventional NiTi GT and M-Wire GTX files. Methodology One hundred and sixty new files (80 GT and 80 GT series X) were divided into four control groups and four experimental groups (n= 20 each). Control groups were new unused files, and new sterilized files. In the experimental groups instruments were used in 3 (GT1 and GTX1 groups) or 4 molars (GT2 and GTX2 groups). Cyclic fatigue resistance was tested in stainless steel curved canals (60°, r = 3mm). Each file was rotated until fracture (300 rpm, 2 N·cm torque). Time to fracture (s) was registered. Mean life, eta and beta parameters of their Weibull distributions were calculated. Results Unused and sterilized GTX files will last significantly longer than GT files with a probability of 75% and 65% respectively, while mean life was significantly longer for GT than for GTX in used files with a probability of 68%. Sterilized GT files will last longer than unused files with a probability of 66%. In both brands, unused and sterilized files will last significantly longer than files used clinically with a probability higher than 98%.The probability that GT will last longer after being used in three rather than four molars was 62% (statistically significant), and 52% (not statistically significant) for GTX. Conclusions GTX files had an extended cyclic fatigue life when compared with GT when they were unused or unused and sterilized, but GT were significantly more resistant to cyclic fatigue after clinical usage than GT series X files 3 mm from the tip. Sterilization of files enhanced the cyclic fatigue resistance of GT instruments. Clinical use of files diminished cyclic fatigue resistance. This article is protected by copyright.

Differences in Cyclic Fatigue Resistance at Apical and Coronal Levels of Reciproc and WaveOne New Files
(Elsevier, 2012) Arias Paniagua, Ana María; Perez-Higueras, Juan José; de la Macorra, José C
Introduction Recent improvements in alloys, kinematics, and concepts have been combined to increase the cyclic fatigue resistance of nickel-titanium (NiTi) instruments. The aim of this study was to compare the cyclic fatigue resistance of new M-Wire reciprocating WaveOne (Dentsply Maillefer, Ballaigues, Switzerland) and Reciproc (VDW GmbH, Munich, Germany) files at 2 levels. Methods Sixty Reciproc and 60 WaveOne new files were fixed to a specifically designed device and tested in tempered steel canals with a 3-mm radius and a 60Â° angle of curvature. The motor used was programmed as defined by each manufacturer, and the specific reciprocating motion was followed. Thirty files of each brand were tested at 5 mm, and 30 were tested at 13 mm from their tips. The time to failure was registered. Weibull analysis was used to calculate the mean life, beta, and eta parameters. Results The probability of the mean life was higher for Reciproc than WaveOne files at both levels, with the probability of the Reciproc mean life being 62% higher than that of WaveOne at 5 mm from the tip and 100% higher at 13 mm (all statistically significant). The probability of the mean life was higher at 5 mm than at 13 mm in both systems. The results may have been partially conditioned by the different motions that manufacturers propose for each system. Conclusions Reciproc files were more resistant to cyclic fatigue than WaveOne files at both distances from the tip. Both systems had greater cyclic fatigue resistance at 5 mm than at 13 mm from the tip.
