RESUMEN
OBJECTIVE: The limitations of spontaneous bone healing underscore the necessity for exploring alternative strategies to enhance bone regeneration in maxillary radicular cyst cases. This retrospective study aimed to assess the impact of a bone substitute material (i.e., Bio-Oss) on bone volume regeneration following maxillary radicular cyst enucleation using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: Seventy-three patients with maxillary radicular cysts were divided into two groups: one undergoing guided bone regeneration (GBR) with Bio-Oss and absorbable collagen membrane (n = 35), and the other receiving cyst excision alone (n = 38). Volumetric measurements using Amira software on CBCT scans evaluated bone regeneration, with cystic lesion shrinkage rates calculated. Intergroup comparisons utilized independent sample t-tests (P < 0.05), and linear regression analysis assessed the influence of preoperative cyst volume and group on bone healing. RESULTS: Both groups showed similar success rates in bone formation at the 12-month follow-up, with no significant differences between them (mean (SD), control: 75.16 (19.17) vs. GBR: 82 (20.22), P > 0.05). Linear regression analysis revealed a negative correlation between preoperative cyst volume and bone regeneration in both groups (P < 0.05). CONCLUSION: Bio-Oss may not significantly enhance bone augmentation in maxillary radicular cysts. In addition, preoperative cyst volume negatively affected the shrinkage rate of cystic lesions. CLINICAL RELEVANCE: Clinicians should consider patient-specific factors such as anatomy and lesion size when determining the need for bone substitute materials. Future research could focus on optimizing treatment protocols and alternative regenerative strategies to improve patient outcomes in maxillary cyst cases.

AIM: Periapical cysts of primary teeth are pathologic entities which are seldom encountered in the clinical practice. Most frequently, these lesions arise in correspondence with primary teeth presenting previous pulp therapy, severe carious lesions, or a history of previous trauma. The aim of the present study is to systematically review the treatment modalities of periapical cysts of the deciduous, along with the reporting of a clinical case. MATERIALS: A case of periapical cyst treated with marsupialization occurring in an 11-year-old patient is described. A literature search was devised to retrieve studies reporting the treatment of periapical cysts, and involved papers published in the Cochrane Oral Health Group specialist trials, MEDLINE via PubMed, and EMBASE up to March 2023. A total of 39 articles were retrieved. Following title and abstract analysis, 27 articles were selected for full-text analysis, with the final inclusion of 24 articles. CONCLUSION: Periapical cysts of primary teeth present an overall good prognosis irrespective of the treatment option adopted. The performance of a prompt diagnosis appears of utmost importance, as the extraction of the primary teeth involved implies the management of the residual space for the correct positioning of the corresponding permanent teeth.

AIM: To evaluate the indication of the endodontic treatment for vital intact teeth with the root apex involved in large radicular cystic lesions of endodontic origin. METHODOLOGY: This prospective cohort study enrolled healthy participants with radicular cysts of endodontic origin and with the root apex of vital intact teeth involved in the bone defect, as determined by cone beam computed tomography (CBCT). Thirty-two sound vital teeth were analysed by thermal (TPT) and electric pulp tests (EPT) before surgery (T0) and 1 week (T1), 2 weeks (T2), 3 months (T3) and 6 months (T4) post-surgery. Student's t-test (p < .05) was used to compare the EPT values at baseline and T4. anova (p < .05) was used to analyse the EPT variations for all maxillary and mandibular teeth. McNemar test (p < .05) was used to compare the results according to variation in EPT values gathering by variation, no variation and no response. RESULTS: At T1, 75 and 65.7% of teeth responded positively whilst 25 and 34.3% did not respond to EPT and TPT, respectively. The variation of the EPT values between T0 and T1 was observed for 50.0% of teeth, whilst no variation was noticed in 25.0% of teeth. At T4, 90.6 and 87.5% of teeth responded positively whilst 9.4 and 12.5% did not respond to EPT and TPT, respectively. At T4, variation of the EPT values between T0 and T4 was observed for 28.1%, whilst no variation was noticed in 62.5% of teeth. There were no statistical differences in EPT results between T0 and T4 (p > .05), but significant differences were observed for EPT values between T1 and T4 (p < .05), and between mandibular and maxillary teeth. The pulp sensibility of maxillary teeth worsened after surgery, before reverting progressively to T0 values, whilst no statistically significant differences were observed for mandibular teeth at the different time points. CONCLUSIONS: These data support the inconsistence of the prophylactic endodontic treatment in healthy vital teeth with apex involvement in large cystic lesions of endodontic origin. Post-surgery follow-up with TPT and EPT is recommended to assess pulp status.

Los quistes periapicales o radiculares representan una de las patologías periapicales más frecuentes dentro del grupo de las lesiones quísticas de los maxilares. Son el resultado de la extensión de proce- sos inflamatorios-infecciosos. Su diagnóstico sigue siendo un desafío para el profesional odontológico, quien debe diferenciarlo de otros procesos inflama- torios periapicales. El objetivo del presente artículo es presentar, apoyado en una revisión de la literatura, el caso clínico de un paciente masculino de 38 años de edad que se presentó a la consulta por leve tume- facción indolora en zona anterosuperior del maxilar. A la inspección se observó borramiento de la región del surco vestibular a nivel de piezas dentarias 1.1, 1.2 y 1.3, de color rojizo con crepitación de la tabla ósea vestibular a la palpación. La tomografía de haz cónico mostró lesión osteolítica, extendida desde zona apical de la pieza dentaria 1.4 hasta zona del elemento dentario 1.1. Se realizó la extirpación de la lesión y api- cectomía. El estudio histológico corroboró el diagnós- tico presuntivo de quiste periapical. Los controles a distancia mostraron buena evolución del tratamiento. Se concluyó en la importancia de realizar un correcto diagnóstico clínico e imagenológico para la selección de un adecuado tratamiento según el caso (AU)
Periapical or radicular cysts represent one of the most frequent periapical pathologies within the group of cystic lesions of the jaws. They are the result of the spread of inflammatory-infectious processes. Its diagnosis continues to be a challenge for the dentist, who must differentiate it from other periapical inflammatory processes. The objective of this article is to present, supported by a review of the literature, the clinical case of a 38-year-old male patient who presented to the consultation due to mild painless swelling in the anterosuperior maxilla. Upon inspection, effacement of the vestibular sulcus region was observed at the level of teeth 1.1, 1.2 and 1.3, reddish in color with crepitation of the buccal bone table on palpation. Cone beam tomography showed an osteolytic lesion that extended from the apical area of tooth 1.4 to area of tooth 1.1. Excision of the lesion and apicoectomy were performed. The histological study corroborated the presumptive diagnosis of periapical cyst. Remote controls showed a good evolution of the treatment. It was concluded on the importance of carrying out a correct clinical and imaging diagnosis for the selection of an adequate treatment according to the case (AU)

Introdução: os cistos radiculares são as lesões císticas mais comuns nos maxilares. Eles surgem dos Restos Epiteliais de Malassez, presos no ligamento periodontal e podem ser ativados por um processo inflamatório na região pulpar. Geralmente são descobertos em exames radiográficos de rotina, apresentando-se como uma imagem radiolúcida, bem delimitada, envolvendo o periápice de um ou mais dentes. Objetivo: apresentar o tratamento de um extenso cisto radicular, em região de maxila, com acompanhamento de 18 meses. Relato do caso: Paciente do sexo feminino, 49 anos, foi encaminhada para avaliação e tratamento na Clínica Odontológica da Faculdade Sete Lagoas (FACSETE), apresentando lesão extensa em região maxilar anterior direita ao exame radiográfico. Ao exame clínico, observou-se leve assimetria facial e ausência de sintomas dolorosos. Tomografia computadorizada, punção aspirativa e biópsia incisional foram utilizadas para se chegar ao diagnóstico compatível com cisto radicular. Optou-se por uma técnica conservadora, em que foi realizada a descompressão da lesão. Após 05 meses de tratamento, um novo procedimento cirúrgico foi realizado para enuclear o restante da patologia. Conclusão: a descompressão, com utilização de cânula, é um tratamento auxiliar fácil, conservador, eficaz e reduz a morbidade causada por diferentes cistos odontogênicos(AU)
Introduction: root cysts are the most common cystic lesions in the jaw. They arise from the Epithelial Remains of Malassez, trapped in the periodontal ligament and can be activated by an inflammatory process in the pulp region. They are usually discovered in routine radiographic examinations, presenting as a well-defined radiolucent image involving the periapex of one or more teeth. Objective: to present the treatment of an extensive root cyst, in the maxillary region, with a follow-up of 18 months. Case report: A 49-year-old female patient was referred for evaluation and treatment at the Dental Clinic of Faculdade Sete Lagoas (FACSETE), with an extensive lesion in the right anterior maxillary region on radiographic examination. On clinical examination, mild facial asymmetry and absence of painful symptoms were observed. Computed tomography, aspiration puncture and incisional biopsy were used to reach a diagnosis compatible with radicular cyst. We opted for a conservative technique, in which the lesion was decompressed. After 05 months of treatment, a new surgical procedure was performed to enucleate the rest of the pathology. Conclusion: decompression, using a cannula, is an easy, conservative, effective auxiliary treatment and reduces the morbidity caused by different odontogenic cysts.

Abstract Objective: This study evaluated the expression of pro-inflammatory (IL-1β, IL-6, IFN-γ and TNF-α) and anti-inflammatory (IL-4 and TGF-β) cytokines in apical periodontitis lesions. Correlations between these cytokines and clinical and cone-beam computed tomographic (CBCT) data were also assessed. Material and Methods: Apical periodontitis lesions' data were obtained from 27 patients subjected to periradicular surgery. Specimens were processed for histopathologic and immunohistochemical analysis. Sections were evaluated according to the amount of positive staining for each antibody. Expression levels of the target mediators were compared with clinical and CBCT data. Results: Twenty lesions were diagnosed as granuloma and 7 as cyst. In granulomas, IL-4 expression was significantly higher than IL-6 (p=0.001) and TNF-α (p=0.001). There was a significant relationship between high levels of TNF-α and lesions <5 mm (p=0.017). In cysts, IL-6 expression was significant lower than IL-4 (p=0.001) and IFN-γ (p=0.004). There was a significant relationship between high levels of TGF-β and endodontic treatment performed ≤4 years before (p=0.045). In general, IL-4 was the most expressed mediator in both cysts and granulomas. Conclusions: There was a balance between the expression of pro-inflammatory and anti-inflammatory cytokines associated with the chronic periradicular inflammatory process. TNF-α and TGF-β were related to some clinical and CBCT data.

Background: Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and them reduction rates involving different factors. Material and Methods: 23 patients with odontogenic cysts of the jaws, previously diagnosed by anatomical histopathology (follicular cysts (7) and radicular cysts (16)) underwent decompression as an initial treatment. Clinical examination and pre and post panoramic radiograph were measured and analyzed. In addition, data as gender, age, time reduction and location of the lesion were collected. Results: Significant results were obtained in relation to the location of lesions and the reduction rate (p< 0.01). In a higher initial lesion, a greater reduction rate was observed (p< 0.05). Conclusions: Decompression as an initial treatment of cystic lesions of the jaws was effective; it reduces the size of the lesions avoiding a possible damage to adjacent structures. Cystic lesions in the mandible, regardless of the area where they occur will have a higher reduction rate if it is compared with the maxilla. Similar behavior was identified in large lesions compared to smaller (AU)

Radicular cyst is the most common inflammatory jaw cystic lesion that occurs in necrotic teeth. They account for more than 50 % of all odontogenic cysts. Radicular cysts cause slowly progressive painless swelling and there are no symptoms until they become large. Enucleating the cyst with endodontic therapy of the affected tooth is recommended as the primary treatment. Here we describe a patient with a large recurrent radicular cyst with maxillary sinus involvement who underwent a midfacial degloving approach for complete enucleation. In conclusion, radicular cyst should be considered in the differential diagnosis of large maxillary sinus lesions and never be discarded until histopathology is available.
El quiste radicular es la lesión inflamatoria quística más común que ocurre en los dientes necróticos. Su presentación abarca más del 50 % de los quistes odontogénicos. Los quistes radiculares se presentan como una inflamación indolora de crecimiento lento y progresivo y se hacen sintomáticas una vez que alcanzan un gran tamaño. El tratamiento primario recomendado para este quiste es la enucleación junto al tratamiento endodóntico de los dientes afectados. Presentamos un reporte de caso de un paciente que presentaba un gran quiste radicular recurrente con envolvimiento de todo el seno maxilar y que fue tratado con un acceso intraoral extendido para lograr la completa enucleación de la lesión. En conclusión, el quiste radicular debe ser siempre considerado en el diagnóstico diferencial de lesiones de gran tamaño que involucren el seno maxilar y nunca ser descartado hasta tener el resultado de histopatología.

A lesão periapical aguda é causada por infecção presente no canal radicular, sendo caracterizada pela presença de exsudato purulento inflamatório nos tecidos perirradiculares. Esse exsudato pode estar localizado intra- e/ou extrabucal e, em alguns casos clínicos, há a necessidade de se realizar drenagem cirúrgica, fato que pode ocasionar desconforto ao paciente. O presente relato de caso descreve uma técnica minimamente invasiva para drenagem de lesão perirradicular aguda na região do incisivo lateral superior direito, utilizando uma sonda de aspiração traqueal conectada no sugador endodôntico. Essa técnica oferece uma drenagem cirúrgica indolor para o paciente e reduz o risco de difusão da infecção. Depois do acesso coronário do elemento envolvido, neutralização precoce do conteúdo séptico e o desbridamento do canal radicular, uma pequena incisão foi realizada na mucosa palatina e imediatamente uma sonda traqueal modificada, sob pressão negativa, foi utilizada para aspirar o exsudato purulento. Na sequência, depois da remissão dos sinais e sintomas agudos, a cirurgia com a obturação endodôntica simultânea do canal radicular foi realizada, utilizando-se um cimento à base de resina epóxi e condensação lateral ativa. A proservação foi realizada por 6 meses, por meio de exames clínicos e radiográficos, demonstrando satisfatória reparação óssea e adequada evolução clínica.

Cistos e granulomas periapicais estão entre as lesões radiolúcidas mais prevalentes. Porém, há situações em que os padrões clínicos e radiográficos se misturam e, portanto, o estudo histopatológico faz-se necessário para o diagnóstico definitivo. O objetivo deste estudo foi avaliar a correlação clínica e histopatológica no diagnóstico de cistos e granulomas periapicais. Para isso, foram selecionadas amostras obtidas no Laboratório de Patologia Cirúrgica da Faculdade de Odontologia de Pernambuco, FOP/UPE, no período de 11/2005 a 05/2008. Um total de 37 lesões, distribuídas entre cistos e granulomas periapicais, foram incluídas no estudo. Baseadas nos aspectos clínico-radiográfico e transoperatório, cirurgiões-dentistas forneceram hipóteses diagnósticas, as quais foram comparadas aos exames histopatológicos. Achados clínicos revelaram 28 casos (75,7%) de cistos, 4 casos (10,8%) de granulomas, 4 casos (10,8%) com características de ambas lesões, e 1 caso (2,7%) no qual o dentista não forneceu o diagnóstico. Entretanto, os achados histopatológicos revelaram 21 (56,8%) e 16 (43,2%) casos de cistos e granulomas, respectivamente. Os resultados mostraram uma correlação de 45,9% entre os achados para os cistos e de 8,1% para os granulomas. Diante do exposto, a discrepância observada dos achados clínicos quando comparados aos histopatológicos deve ser discutida quanto aos critérios diagnósticos que vêm sendo utilizados atualmente...

Cysts and periapical granulomas are among the most prevalent radiolucent lesions. However, there are situations where the clinical and radiographic patterns are mixed and therefore the histopathological study is necessary for definitive diagnosis. The aim of this study was to evaluate the clinical and histopathological correlation in the diagnosis of periapical cysts and granulomas. For this, samples were selected obtained from histopathological reports of Pathology Laboratory, Faculty of Dentistry of Pernambuco, FOP / UPE, during the period from 11/2005 to 05/2008. A total of 37 lesions distributed among periapical cysts and granulomas, were included in the study. Based on clinical, radiographic and intraoperative lesions, dentists provided diagnostic hypotheses, which were compared to histopathological diagnostic. Clinical findings revealed 28 cases (75.7%) of radicular cysts, 4 cases (10.8%) of granulomas alone, 4 cases (10.8%) with characteristics of both lesions, and 1 case (2.7 %) in which the dentist has not provided the diagnosis. However, the histopathological findings revealed 21 (56.8%) and 16 (43.2%) cysts and granulomas images, respectively. The results showed a 45.9% correlation between the findings for periapical cysts and 8.1% for periapical granulomas. Given the above, the discrepancy observed clinical findings compared to histopathology should be discussed as to the diagnostic criteria that have been used nowadays... (AU)

El quiste radicular es la lesión más común en el hueso maxilar, siendo el diente más afectado el incisivo lateral. La técnica quirúrgica permite una variada gama de procedimientos de exéresis para dar solución a la erradicación de la lesión, pasando desde sólo la preservación del coágulo postquirúrgico a novedosas técnicas regenerativas. Este caso muestra el resultado de la utilización de hueso humano liofilizado y membrana reabsorbible postexéresis de quiste radicular como procedimiento exitoso.
The radicular cyst is the most common injury in the jawbone, and the lateral incisor is the most affected tooth. The surgical technique allows a wide range of excision procedures to solve the eradication of injury, from the preservation of post-surgical blood clot to novel regenerative techniques. This case shows the result of the use of lyophilized human bone and resorbable membrane, after resection of radicular cyst as successful procedure.

A 47 year old female patient of dark skin colour, resident in an urban community that, with PPA of arterial hypertension without treatment; she has an acute chronic inflammation of the right hard palate, the oral examination shows total destruction of the crown on tooth 12 (upper right lateral incisor) with increase of diffuse volume in the palate; visible in an occlusal x-ray, a rounded radiolucyd area of more than 1.5cm of diameter is observed, with a radiopaque limitation in tooth apex in question, and this apex is intact, what impresses a radicular debris of tooth 12 with a periapical cyst. It is decided to be referred to maxillo facial surgery services where the cyst is eliminated, the capsule is extracted, the sample is taken, exodontia of radicular tooth debris is carried out, it is irrigated with solution and it is sutured; in next appointment the patient presents good evolution and a report of the biopsy is obtained resulting: presence of several fragments of fibrous tissue with acute chronic inflammation with bleeding areas(AU)

El tratamiento endodóntico-quirúrgico en dientes con quistes inflamatorios radiculares es un desafío clínico debido a su complejidad, y más aún si están en piezas con anomalías de desarrollo dental, como lo es la geminación dentaria. A continuación se presenta un caso clínico en el que se logra la reparación de una lesión apical mediante una necropulpectomía de la pieza geminada y enucleación del quiste adyacente.
The surgical-endodontic treatment of teeth with an inflammatory radicular cyst is a clinical challenge due to its great complexity. Even more so, if they are in teeth with development anomalies such as gemination. The case below shows the repair of an apical lesion by a necro-pulpectomy of the geminated tooth and the enucleation of the adjacent cyst.

Introducción: El quiste periapical es una lesión inflamatoria común de los maxilares, que al alcanzar un tamaño significativo, causa deformidad del hueso afectado, retención o incluso el desplazamiento de dientes adyacentes. Se presentó caso de paciente que acudió a consulta odontológica, por presencia de sintomatología dolorosa durante el consumo de alimentos. Al examen clínico se observó encía adherida con presencia de inflamación y enrojecimiento a nivel de órgano dentario 14; radiográficamente se evidenció imagen radiolúcida unilocular, bien definida, abarcando dicho órgano dentario. La lesión fue eliminada quirúrgicamente con la posterior aplicación de material sellador. En el control postoperatorio se observó adecuado proceso de cicatrización y ausencia de sintomatología. Discusión: Se reporta caso de quiste periapical, que ocupaba el periápice de órgano dentario posterosuperior derecho. Radiográficamente se evidenció variabilidad mínima en el tamaño de la imagen. Se describe su resección quirúrgica y se informan los hallazgos de histopatología. En la revisión bibliográfica realizada se determinó la importancia de la elección de las radiografías periapicales en el área de endodoncia, y su papel en el diagnóstico, planificación de tratamiento y seguimiento de las piezas dentarias y tejidos circundantes comprometidos, pese a los inconvenientes de la técnica radiográfica (AU)
Introduction: The periapical cyst is a common inflammatory lesion of the jaws. When the cyst reaches a significant size, it cause a deformity of the affected bone, retention or displacement of adjacent teeth. The case of a patient was presented who went to dental appointment because the presence of painful symptomatology during food consumption. A clinical examination revealed that gingiva was red and swollen at tooth 14; radiographically evidenced a unilocular radiolucency which covered the dental organ. The lesion was excised surgically with the subsequent application of sealant material. After surgery, was evidenced healing and the patient was no longer in pain. Discussion: We report a case of periapical cyst, which occupied the dental organ periapex upper right posterior. Radiographically evidenced minimal variability in the size of the image. Its resection is described and we inform the histopathological findings. In the literature review we found the importance of the choice of periapical x-rays in the endodontic area, and its role in the diagnosis, treatment planning and monitoring of the teeth and surrounding tissues involved, despite the drawbacks of traditional radiographic technique (AU)

Se realiza una revisión sobre el diagnóstico diferencial entre ameloblastoma y quisteradicular residual. El ameloblastoma es un tumor benigno, del epitelio odontogénico, al igual que el quiste residual, que a su vez debe estar relacionado con un diente y aexodonciado en la arcada. En el caso que se presenta, el diagnóstico de presunción fue un ameloblastoma y el diagnóstico de certeza anatomopatológico final, reveló que se trataba de un quiste radicular residual. Se trataba de un varón de 66 años, que acudió a Consulta en el Hospital Universitario de Madrid-Torrelodones para rehabilitar con implantes las zonas edéntulas que presentaba, se solicitó una ortopantomografía, que reveló una lesión radiolúcida, de bordes definidos con tamaño aproximado de 10x3cm, localizado en el cuerpo mandibular derecho, sin manifestaciones clínicas. Se realiza la exéresis de la lesión bajo anestesia general, y se rellena la cavidad con un aloinjerto óseo desmineralizado para rehabilitar posteriormente con implantes (AU)
A review is made on the differential diagnosis between ameloblastoma and residual radicular cyst. The ameloblastoma is a benign tumour of the odontogenic epithelium, like the residual cyst which in turn must be related to a tooth already extracted in the arch. In the case that is presented, the certain final anatomopathological diagnosis revealed that it was a residual radicular cyst. The case dealt with a male of 66 years of age, who went to the Office of the Hospital Universitario de Madrid-Torrelodones to rehabilitate the edentulous areas with implants; an orthopantomograph was requested, which revealed a radiolucent lesion, with defined borders and a size of approximately 10x3 cm, located in the right mandibular body, without clinical symptoms. The excision of the lesion was performed under general anaesthesia and the cavity filled with a demineralized bone allograft to later rehabilitate with implants (AU)
