RESUMO

Resumo Introdução: Os pinos de fibra de vidro têm sido amplamente utilizados na reconstrução de elementos com perda excessiva de estrutura dentária. Objetivo: Avaliar a força de adesão de pinos de fibra de vidro após diferentes tratamentos radiculares em diferentes regiões (terço cervical, médio e apical) da dentina radicular. Métodos: Este é um estudo experimental in vitro. Quarenta dentes bovinos foram selecionados, preparados e distribuídos em quatro grupos de acordo com o tratamento de superfície utilizado: adesivo (1), agente quelante (2), ácido poliacrílico (3), não tratado (4). A cimentação dos pinos de fibra de vidro foi realizada com cimento resinosante autocondicionante. Após vinte dias, cada raiz foi cortada em três fatias (um milímetro de espessura) obtidas de três regiões. A resistência de união de cada seção foi determinada usando um teste de resistência da junta de encaixe. Os dados de resistência à flexão (MPa) foram analisados pelos testes ANOVA e Tukey (α = 0,05). Resultados: Na porção cervical, o grupo com tratamento prévio com ácido poliacrílico apresentou menor resistência ao cisalhamento por extrusão (push-out) do que o grupo sem tratamento prévio. O grupo com aplicação do sistema adesivo (28,89 ± 6,64 MPa) e o grupo com tratamento prévio com EDTA (21,58 ± 6,39 MPa) não apresentaram diferenças estatisticamente significantes em relação ao grupo sem tratamento prévio (grupo controle) no terço cervical. Nas porções média e apical, o grupo tratado com adesivo FGM Ambar apresentou maiores valores de ligação em comparação com os outros grupos. Conclusão: A aplicação prévia do adesivo aumentou a resistência de união nos terços médio e apical, em comparação aos outros grupos, podendo ter um efeito benéfico no sucesso clínico do tratamento restaurador(AU)


Resumen Introducción: Los postes de fibra de vidrio se han utilizado ampliamente en la reconstrucción de elementos con pérdida excesiva de estructura dental. Objetivo: Evaluar la fuerza de adhesión de postes de fibra de vidrio después de distintos tratamientos de raíz en diferentes regiones (tercios cervical, medio y apical) de dentina de raíz. Métodos: Estudio experimental in vitro. Se seleccionaron cuarenta dientes bovinos, se prepararon y se distribuyeron en cuatro grupos de acuerdo con el tratamiento de superficie utilizado: (1) adhesivo, (2) agente quelante, (3) ácido poliacrílico, (4) sin tratar. La cementación de los postes de fibra de vidrio se realizó con cemento de resina autograbante. Después de 20 días, cada raíz se seccionó transversalmente en tres rodajas (1 mm de espesor) obtenidas de tres regiones. La resistencia a la unión de cada sección se determinó usando una prueba de resistencia al corte por extrusión (push-out). Los datos de resistencia a la flexión (MPa) se analizaron mediante pruebas ANOVA y Tukey (α = 0,05). Resultados: En la porción cervical, el grupo con tratamiento previo de ácido poliacrílico mostró menor resistencia que el grupo sin tratamiento previo. El grupo con aplicación del sistema adhesivo (28,89 ± 6,64 MPa) y el grupo con tratamiento previo de EDTA (21,58 ± 6,39 MPa) no presentaron diferencias estadísticamente significativas en comparación con el grupo sin tratamiento previo (grupo control) en el tercio cervical. En las porciones media y apical, el grupo tratado con adhesivo Ambar® de FGM Dental Group mostró valores más altos de unión en comparación con los otros grupos. Conclusión: La aplicación previa del adhesivo aumentó la fuerza de unión en los tercios medio y apical, en comparación con los otros grupos, puede tener un efecto beneficioso sobre el éxito clínico del tratamiento restaurador(AU)


ABSTRACT Introduction: Glass fiber posts have been widely used for the reconstruction of elements with excessive dental structure loss. Objective: Evaluate the bond strength of glass fiber posts after various root dentin treatments in different regions (cervical, middle and apical thirds). Methods: An experimental in vitro study was conducted. Forty bovine teeth were selected, prepared and distributed into four groups according to the surface treatment used: (1) adhesive, (2) chelating agent, (3) polyacrylic acid, (4) not treated. The glass fiber posts were cemented with self-etch resin cement. After 20 days, each root was sectioned crosswise into three slices (1 mm in thickness) obtained from three regions. Bond strength was determined in each section with a push-out bond strength test. Flexural strength data (MPa) were analyzed with ANOVA and Tukey's tests. Results: In the cervical portion, the group with previous polyacrylic acid treatment displayed lower push-out strength than the group without previous treatment. The group with application of the adhesive system (28.89 ± 6.64 MPa) and the group with previous EDTA treatment (21.58 ± 6.39 MPa) did not exhibit any statistically significant differences in comparison with the group without previous treatment (control group) in the cervical third. In the middle and apical portions, the group treated with the adhesive Ambar® of FGM Dental Group showed higher bond values in comparison with the other groups. Conclusion: Previous adhesive application increased bond strength in the middle and apical thirds in comparison with the other groups, and may thus have a beneficial effect on the clinical success of the restorative treatment(AU)

RESUMO

Purpose: To present an evidence-based guideline for non-vital pulp therapies due to deep caries or trauma in primary teeth. Methods: The authors, working with the American Academy of Pediatric Dentistry, conducted a systematic review/meta-analysis for studies on non-vital primary teeth resulting from trauma or caries and used the GRADE approach to assess level of certainty of evidence for clinical recommendations. Results: GRADE was assessed from high to very low. Comparing teeth with/without root resorption, pulpectomy success was better (P<0.001) in those without preoperative root resorption. Zinc oxide plus iodoform plus calcium hydroxide ([ZO/iodoform/CH]; Endoflas TM ) and zinc oxide and eugenol (ZOE) pulpectomy success did not differ from iodoform (iodoform plus calcium hydroxide; VitapexTM, MetapexTM) (P=0.55) after 18-months; however, ZO/iodoform/CH and ZOE success rates remained near 90 percent while iodoform was 71 percent or less. Network analysis ratings showed ZO/iodoform/CH and ZOE better than iodoform. Lesion sterilization tissue repair (LSTR) was better (P<0.001) than pulpectomy in teeth with preoperative root resorption, but pulpectomy results were better (P=0.09) if roots were intact. Rotary instrumentation of root canals was significantly faster (P<0.001) than manual, but the quality of fill did not differ (P=0.09) and both had comparable success. Network analysis ranked ZO/iodoform/CH the best, ZOE second, and iodoform lowest at 18 months. Success rates were not impacted by method of obturation or root length determination, type of tooth, number of visits, irrigants, smear layer removal, or timing/type of final restoration. Conclusions: Pulpectomy 18-month success rates supported ZO/iodoform/CH and ZOE pulpectomy over iodoform. LSTR had limited indication for teeth with resorbed roots and requires close monitoring.

RESUMO

OBJECTIVES: To develop a clinical practice guideline on orthodontically induced external apical root resorption (EARR), with evidence-based and, when needed, consensus-based recommendations concerning diagnosis, risk factors, management during treatment, and after-treatment care. MATERIALS AND METHODS: The Appraisal of Guidelines for Research and Evaluation II instrument and the Dutch Method for Evidence-Based Guideline Development were used to develop the guideline. Based on a survey of all Dutch orthodontists, we formulated four clinical questions regarding EARR. To address these questions, we conducted systematic literature searches in MEDLINE and Embase, and we performed a systematic literature review. The quality of evidence was assessed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. After discussing the evidence, a Task Force formulated considerations and recommendations. The drafted guideline was sent for comments to all relevant stakeholders. RESULTS: Eight studies were included. The quality of evidence (GRADE) was rated as low or very low. Only the patient-related risk factors, 'gender' and 'age', showed a moderate quality of evidence. The Task Force formulated 13 final recommendations concerning the detection of EARR, risk factors, EARR management during treatment, and after-treatment care when EARR has occurred. Stakeholder consultation resulted in 51 comments on the drafted guideline. After processing the comments, the final guideline was authorized by the Dutch Association of Orthodontists. The entire process took 3 years. LIMITATIONS: The quality of the available evidence was mainly low, and patient-reported outcome measures were lacking. CONCLUSIONS/IMPLICATIONS: This clinical practice guideline allows clinicians to respond to EARR based on current knowledge, although the recommendations are weak due to low-quality evidence. It may reduce variation between practices and aid in providing patients appropriate information.

RESUMO

OBJECTIVES: The aim of this study is to investigate the effect of photobiomodulation therapies on root resorption compared with the placebo group. MATERIALS AND METHODS: Thirty patients who were admitted to the Gaziantep University Faculty of Dentistry Orthodontics Department for treatment, with an indication of upper right first premolar tooth extraction were included. Before the individuals' orthodontic treatment, 0.022 slot MBT brackets and tubes were placed on the maxillary first premolar and molar. A 150-g buccal tipping force was applied to the first premolar. Cantilever spring with 0.017 × 0.025 Beta Titanium wire was used for force application. Individuals were then randomly divided into three groups. For the first group, laser application was performed with an 810-nm GaAlAs laser device at 0, 3, 7, 14, 21, and 28 days to 8 J/cm2. For the second group, an LED application according to the manufacturer's instructions with an 850-nm wavelength and 20 mW/cm2 output power for 10 min per day during the experiment. For the third group, a placebo therapy was completed whereby a laser device that did not make active pulses was used. At the end of 4 weeks, the amount of root surface resorption was compared using micro-CT imaging after the extraction of the teeth. RESULTS: No significant difference was found between the groups in terms of regional and total crater volumes. It was observed that photobiomodulation therapies were not different from the control group in terms of forming root resorption. CONCLUSIONS: It is seen that laser and LED photobiomodulation therapies used for accelerate orthodontic tooth movement do not differ from the control group in terms of forming root resorption. CLINICAL RELEVANCE: According to the results of this pilot study on this subject, which needs to be clarified with new findings in the future, LED and laser applications may not increase the risk for root resorption.

RESUMO

La resorción radicular externa generalizada representa un problema a la hora de realizar un tratamiento de ortodoncia, requiere la toma de decisiones que siempre debe estar fundamentada en el diagnóstico llevado a cabo mediante un equipo interdisciplinario. Objetivo: Describir el tratamiento a una paciente con resorción radicular generalizada ante un proceso completo de diagnóstico que debe ser seguido, buscando preservar la estructura dentaria y la inserción conectiva. Caso clínico: Mujer de 14 años de edad, con motivo de consulta: «tengo un diente fuera de lugar¼, con un biótopo dolicofacial, y maloclusión clase II esquelética, clase I molar, clase I canina, discrepancia osteodentaria negativa, perfil convexo, incompetencia labial, incisivo lateral superior cruzado, resorción radicular generalizada, que predomina en incisivos anteriores superiores. El tratamiento fue ortodoncia (con aparatología fija Roth slot 22), extracciones de segundos premolares superiores e inferiores, cierre de espacios acelerado y ajuste oclusal. Resultado: Al finalizar el tratamiento, se logró mejorar la estética, preservación de la inserción conectiva, estructura dental y una oclusión funcional. Conclusiones: Los pacientes con resorción radicular generalizada necesitan ser diagnosticados correctamente, es importante saber que los resultados se limitan a utilizar fuerzas ligeras y controladas, y es de gran utilidad el aprovechamiento del fenómeno de aceleración regional que está dado por las extracciones dentales, cerrando los espacios desde estadios iniciales del tratamiento (AU)


Generalized external root resorption represents a problem when performing orthodontic treatment, it requires making decisions that should always be based on the diagnosis carried out by an interdisciplinary team. Objective: To describe the treatment of a patient with generalized radicular resorption with a complete diagnostic process that must be followed in order to preserve the tooth structure and the connective insertion. Case report: 14-year-old female patient, with reason for consultation: «I have a tooth out of place¼', with a dolichofacial biotype, class II skeletal malocclusion, class I molar, class I dog, negative osseous discrepancy, convex profile, lip incompetence, superior lateral incisor crossed, generalized radicular resorption, which predominates in upper anterior incisors. The treatment was orthodontics (with Roth slot 22 fixed appliances), extractions of upper and lower second premolars, accelerated space closure and occlusal adjustment. Result: At the end of the treatment, aesthetics, preservation of the insertion and dental structure and a functional occlusion were achieved. Conclusions: Patients with generalized root resorption need to be diagnosed correctly, it is important to know that the results are limited to use light and controlled forces and it is very useful to take advantage of the phenomenon of regional acceleration that is given by the dental extractions, closing the spaces from initial stages of treatment (AU)

RESUMO

The process of resorption of hard tooth tissues is associated with the activity of osteoclasts. However, the initiation of resorption can be caused by many factors acting separately or simultaneously. The paper presents the characteristics of pathological tooth resorption. The main etiological factors, pathogenesis, clinical manifestations, as well as treatment of various forms of tooth resorption are described.

RESUMO

OBJECTIVE: The aim was to assess the influence of low-level laser therapy (LLLT) on orthodontically-induced inflammatory root resorption (OIIRR). METHODS: A systematic search was conducted in indexed databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The eligibility criteria were as follows: (a) original clinical and animal/experimental studies; (b) prospective studies; (c) intervention: effect of LLLT on OIIRR; (d) control group (OIIRR without LLLT); (e) statistical analysis; and (f) tomographic or histologic assessment of OIIRR. Quality assessment of the experimental and clinical studies was performed following the Animal Research Reporting In-vivo Experiments (ARRIVE) and Consolidated Standards of Reporting Trials (CONSORT) guidelines, respectively. The risk of bias of the included studies was also determined. RESULTS: Nine (7 experimental and 2 clinical) of the initially identified 39 studies were included. One clinical and 2 experimental studies showed that LLLT during orthodontic tooth movement (OTM) significantly reduces OIIRR. One experimental study reported that LLLT during OTM in sockets treated with alloplastic materials significantly reduces OIIRR. One experimental study found that LLLT after OTM significantly repairs OIIRR, whereas one clinical study did not report a significant reparative affect. Three experimental studies showed that LLLT increases OIIRR during OTM, corticotomized-OTM, and OTM into grafted defects, respectively. The minimum, median and highest ARRIVE scores (out of 20) of the included experimental studies were 15, 17 and 19, respectively. The mean CONSORT score of the included clinical studies was 23 (out of 25). CONCLUSIONS: In conclusion, the influence of LLLT on OIIRR remains debatable.

RESUMO

Tooth autotransplantation is performed in patients with congenitally missing teeth and those with traumatic tooth loss. We report a course of edgewise treatment of a girl with multiple congenitally missing teeth and residual features of ectodermal dysplasia, who was treated with autotransplantation of 2 premolars with developing roots. She was 8 years old at the beginning of the treatment. No signs of inflammation, root resorption, or pulp symptoms were observed during the 2.5 years of edgewise treatment after autotransplantation. Cervical external root resorption was detected 31 months postoperatively in 1 transplanted tooth (maxillary first premolar), and the same problem occurred in the other transplanted tooth (mandibular second premolar) 2 years later. Root canal treatment was immediately undertaken and resulted in inhibition of further pathology. Consequently, the survival of both transplanted teeth was achieved. The orthodontic treatment that included intervals related to diagnosis and treatment of root resorption of the transplanted premolars is described in detail.

RESUMO

This Position Statement represents the consensus of an expert committee convened by the European Society of Endodontology (ESE) on External Cervical Resorption (ECR). The statement is based on current clinical and scientific evidence as well as the expertise of the committee. The primary aim is to provide a current authoritative position on the aetiology, histopathology, clinical presentation and management of ECR, and also to highlight areas where there is minimal evidence. Previously published review articles provide more detailed background information and the basis for this position statement (International Endodontic Journal 51, 1205, 2018, International Endodontic Journal 51, 1224, 2018). It is intended that this position statement will be updated at appropriate intervals, as further evidence emerges.

RESUMO

Effective management of external cervical resorption (ECR) depends on accurate assessment of the true nature and accessibility of ECR; this has been discussed in part 1 of this 2 part article. This aim of this article was firstly, to review the literature in relation to the management of ECR and secondly, based on the available evidence, describe different strategies for the management of ECR. In cases where ECR is supracrestal, superficial and with limited circumferential spread, a surgical repair without root canal treatment is the preferred approach. With more extensive ECR lesions, vital pulp therapy or root canal treatment may also be indicated. Internal repair is indicated where there is limited resorptive damage to the external aspect of the tooth and/or where an external (surgical) approach is not possible due to the inaccessible nature of subcrestal ECR. In these cases, root canal treatment will also need to be carried out. Intentional reimplantation is indicated in cases where a surgical or internal approach is not practical. An atraumatic extraction technique and short extraoral period followed by 2-week splinting are important prognostic factors. Periodic reviews may be indicated in cases where active management is not pragmatic. Finally, extraction of the affected tooth may be the only option in untreatable cases where there are aesthetic, functional and/or symptomatic issues.

RESUMO

Root resorption is a poorly understood phenomenon and is often misdiagnosed and, as a result, inappropriately treated. The aim of this paper is to provide a practical guide for diagnosis of root resorption lesions using a simple classification, and to describe the principles of management of these resorptive defects in everyday practice.

RESUMO

A Reabsorção Radicular Externa por Substituição (RRES) consiste na substituição da estrutura dentária por tecido ósseo. O atual consenso é de que não há terapia pertinente para tal processo. Uma revisão de literatura com enfoque em protocolos terapêuticos utilizados em dentes traumatizados e seus efeitos sobre a RRES será apresentada. Para tal, artigos científicos na língua inglesa foram reunidos por meio das bases de dados Pubmed Central, Scopus, Embase Medline, Ovid e Cochrane, utilizando as seguintes palavras chaves: Tooth Resorption, Root Resorption, Tooth Injuries, Root Canal Therapy, Ankylosis. Estudos demonstraram que anquilose e RRES se desenvolveram nas superfícies dentárias independentemente do medicamento utilizado no interior do canal. Dentes tratados com hidróxido de cálcio e guta-percha apresentaram maior predominância de deposição óssea. Corticoides demonstraram resultados promissores, observando-se reparo favorável e menor taxa de RRES. Não foram encontrados artigos relatando tentativas interceptativas frente ao processo de reabsorção por substituição. Apesar de sua ocorrência ter se demonstrado frequente, tentativas de controle do processo instalado são relevantes, considerando- se que a ausência de tratamento resulta na pior consequência possível: a perda dentária.

RESUMO

La reabsorción cervical invasiva (RCI) es un tipo de reabsorción radicular insidiosa y agresiva que se origina en la superficie radicular externa. Típicamente, suele pasar inadvertida puesto que en la mayoría de los casos es asintomática. El uso de la tomografía computarizada con haz cónico (CBCT) mejora el diagnóstico y la planificación y la utilización dental mejora la realización del tratamiento. El objetivo principal de un tratamiento óptimo de ICR es la eliminación e inactivación del proceso de reabsorción y la reconstrucción del defecto. Entre los materiales empleados en la literatura para el sellado del defecto, el composite parece ser una opción válida. En el presente caso clínico se describe el tratamiento combinado quirúrgico-endodóncico de una reabsorción cervical invasiva clase III de Heithersay sellada con composite. Después de un año de seguimiento, el paciente se mostraba asintomático y la rarefacción ósea peri radicular ha disminuido significativamente no existiendo recidiva de la reabsorción


Invasive cervical resorption (ICR) is an aggressive type of radicular resorption that originates in the external radicular surface. It can typically go unnoticed since it is often asymptomatic. The use of cone beam computed tomography (CBCT) increases in a greater diagnostic and planning and a dental microscope increases the proper execution of the treatment. The main objective of an optimal treatment of ICR is the elimination and inactivation of the resorptive process, and the reconstruction of the defect. Among the dental material used in the literature for sealing the defect, composite seems to be a valid option. The present case-report describes a combined surgical and endodontic treatment of a Heithersay class III invasive cervical resorption sealed with dental composite. A one-year follow-up shows the patient to be asymptomatic, and the bone rarefaction to have decreased significantly, with no evidence of a resorption recurrence

RESUMO

External cervical root resorption begins at the root surface as result of odontoclastic activity in the cervical area and is progressive in character. The pulp is only affected at a later stage of the process. The aetiology and pathogenesis of external cervical root resorption is not fully understood. Possible predisposing factors are, among others, orthodontic treatment, trauma, internal bleaching, damaged cemento-enamel junction, bruxism and hypoxia. A 'pink spot' often is the first clinical sign and a two-dimensional radiograph usually presents an amorphous radiolucency with undefined borders. Cone-beam computed tomography is an emerging technique aiding the diagnosis of and prognosis and treatment plans for external root resorption. An external or internal treatment approach can be chosen, depending on the size of the defect.

RESUMO

The aim of this case report is to describe the treatment of an 11-year-old boy who was referred to an endodontist for evaluation of external inflammatory root resorption in the distal apical third of the permanent maxillary left lateral incisor, caused by deviation in the eruption path of the permanent maxillary left canine. The results of the pulpal sensitivity test of the permanent maxillary left lateral incisor were inconclusive and similar to those for the homologous tooth, so the endodontist opted for a clinical and radiographic follow-up. The patient was referred to an orthodontist, who placed a fixed Haas-type palatal expander. After the eruption of all permanent teeth, the orthodontist placed a fixed orthodontic appliance. After approximately 3 years of monitoring, bone repair with dental remodeling was observed, and the results of a pulpal sensitivity test were positive. This case demonstrates that proper monitoring is critical in establishing the diagnosis and treatment plan and ultimately to the success of clinical management.

RESUMO

Multiple invasive cervical resorption (MICR) is a rare disease of unknown etiology. A case of a patient with MICR of six teeth, with low vitamin D3 level detected, is presented. Applied surgical and general treatments were only partially effective, as they failed to stop the resorption, although the parameters of calcium-phosphate management appreciably improved, and secondary hyperparathyroidism was successfully resolved.

RESUMO

BACKGROUND: Accurate working length (WL) determination is necessary in achieving optimal healing by non-surgical root canal therapy in teeth with inflammatory apical root resorption. Electronic apex locators (EALs) are one of the mainstays in determination of WL of teeth. AIM: This study evaluated the accuracy of three EALs [RootZX (third generation), iPex (fourth generation) and Raypex 6 (modification of a fifth generation)] in determining the WL of teeth with simulated apical root resorption in permanent teeth. MATERIALS AND METHODS: Forty freshly extracted maxillary anterior teeth were collected and a 45° oblique cut was made at the root apex with a disc to simulate apical root resorption. Actual working length (AWL) was determined by direct visual method and was used as a control. Electronic working length (EWL) values were measured by three different apex locators that are RootZX (Group I), iPex (Group II) and Raypex 6 (Group III) at apex, 0.5 mm and 1 mm from apex. All values obtained were tabulated and statistical evaluation was carried out. RESULTS: At apex, EWL obtained using iPex (p=0.05) showed a statistically significant difference from AWL. At 0.5 mm and 1.0 mm tolerance, iPex showed non-acceptability for WL measurement in 67.5% and 17.5% of samples compared to Root ZX (12.5% and 2.5%) and Raypex (7.5% and none) respectively. CONCLUSION: Within the limitation of this study, it can be concluded that Raypex 6 and RootZX show statistically significant accuracy in WL measurement compared with iPex in teeth with apical root resorption.

RESUMO

Objective: The aim of this study was to evaluate and compare the reparative and inhibitory effects of a light-emitting diode-mediated photobiomodulation (PBM) and of a low-intensity pulsed ultrasound (LIPUS) on orthodontically induced inflammatory root resorption (OIIRR). Materials and methods: Forty-nine Wistar rats were divided into four groups: untreated group (negative control), group treated with orthodontic appliances (positive control), PBM-treated group (wavelength: 618 nm, output power density: 20 mW/cm2), and LIPUS-treated group (frequency: 1.5% ± 5% MHz, pulse repetition ratio: 1.0% ± 10% kHz, effect area: 3.88% ± 1% cm2 and intensity: 30% ± 30% mW/cm2). OIIRR was induced experimentally in rats for 14 days with an applied force of 100g, and therapeutic approaches were performed concurrently. At the end of the experiment, upper first molar teeth of rats were prepared for genetic analysis, scanning electron microscopy, hematoxylin and eosin staining, and tartrate-resistant acid phosphatase staining. Kruskal-Wallis and post hoc Dunn's tests were performed. Results: Number of osteoclasts (p < 0.01), number of resorption lacunae and resorption area ratio (p < 0.001) decreased and number of total cells (p < 0.001) increased with the PBM and LIPUS applications when compared with the positive control group. Receptor activator of nuclear factor kappa B ligand (RANKL) levels of PBM and LIPUS groups were lower (p < 0.001), and osteoprotegerin (OPG) levels were higher (p < 0.001) than the positive control group. Cyclooxygenase-2 (Cox-2) expression significantly decreased with LIPUS and PBM administrations (p < 0.05). No significant difference was observed among PBM and LIPUS groups. Conclusions: PBM and LIPUS applications showed marked inhibitory and reparative effects on OIIRR by modulating the OPG/RANKL ratio, Cox-2 expression, and cell differentiation of osteoblasts and osteoclasts.

RESUMO

AIM: To present the regenerative endodontic treatment procedure of a perforated internal root resorption case and its clinical and radiographic findings after 2 years. SUMMARY: A 14-year-old female patient was referred complaining of moderate pain associated with her maxillary left lateral incisor. After radiographic examination, a perforated internal resorption lesion in the middle third of tooth 22 was detected. Under local anaesthesia and rubber dam isolation, an access cavity was prepared and the root canal was shaped using K-files under copious irrigation with 1% NaOCl, 17% EDTA and distilled water. At the end of the first and second appointments, calcium hydroxide (CH) paste was placed in the root canal using a lentulo. After 3 months, the CH paste was removed using 1% NaOCl and 17% EDTA solutions and bleeding in the root canal was achieved by placing a size 20 K-file into the periapical tissues. Mineral trioxide aggregate was then placed over the blood clot. The access cavity was restored using glass-ionomer cement and resin composite. After 2 years, the tooth was asymptomatic and radiographic examination revealed hard tissue formation in the perforated resorption area and remodelling of the root surface. KEY LEARNING POINTS: Regenerative endodontic treatment procedures are an alternative approach to treat perforated internal root resorption lesions. Calcium hydroxide was effective as an intracanal medicament in regenerative endodontic treatment procedures.
