RESUMO

Traumatic and especially inflammatory-infectious dental lesions are very prevalent in our context. Inflammatory-infectious disease is usually discovered incidentally on imaging studies that include the orofacial region. Moreover, these conditions can result in potentially severe complications, so early diagnosis and treatment are important. Multidetector computed tomography offers good diagnostic performance for dental lesions, although the radiological findings can be subtle and can go undetected if the radiologist is not familiar with them. Likewise, invasive dental procedures are becoming increasingly common, and these can also result in complications. On the other hand, in daily practice a variety of radiolucent mandibular lesions or developmental anomalies can lead to erroneous interpretations. For these reasons, radiologists should be familiar with possible findings related with dental conditions.

RESUMO

La patología dentaria traumática y en especial la inflamatorio-infecciosa son muy prevalentes en nuestro medio. Esta última suele encontrarse de forma incidental en muchos de los estudios radiológicos que incluyen la región orofacial. Además, es una potencial causa de complicaciones graves, lo que hace que su diagnóstico y tratamiento precoz sean importantes. La tomografía computarizada multidetector ofrece un buen rendimiento diagnóstico en la patología dentaria, aunque sus manifestaciones radiológicas pueden ser sutiles y si no se conocen, pasar desapercibidas. Asimismo, son cada vez más frecuentes los procedimientos dentales invasivos, no exentos de complicaciones. Por otra parte, en la práctica diaria pueden encontrarse variedad de lesiones mandibulares radiolucentes o anomalías del desarrollo que pueden llevar a interpretaciones erróneas. Por todo ello, es recomendable que el radiólogo esté familiarizado con los posibles hallazgos en la patología dentaria.(AU)

RESUMO

La periodontitis apical es una patología inflamatoria que afecta los tejidos periapicales de un diente desvitalizado. El objetivo de este estudio fue caracterizar histológica y morfométricamente las lesiones de quistes y granulomas utilizando microscopía óptica. Se analizaron seis biopsias obtenidas de dientes con indicación de exodoncia. El análisis histológico se realizó mediante microscopía óptica y microfotografías, con análisis de contraste de imágenes y conteo celular mediante ImageJ. Descripción de las características histológicas: en los quistes se observaron cavidades rodeadas de epitelio escamoso estratificado no queratinizado y una cápsula fibrosa compuesta de fibrocitos, fibroblastos e infiltrado inflamatorio crónico; en los granulomas se observaron capilares, una capsula fibrosa de fibrocitos/fibroblastos y un infiltrado inflamatorio de predominio linfocitario. Cuantificación del número celular de infiltrado inflamatorio: para quistes fue de 9,2 cel/10000 µm2, mientras que para granulomas fue de 20,8 cel/10000 µm2, sin diferencias estadísticas significativas entre ambos (p=0,654). Cuantificación del número celular de fibrocitos/fibroblastos: para quistes fue de 15,4 cel/10000 µm2, mientras que para granulomas fue de 18,5 cel/10000 µm2, sin diferencia estadística significativa (p=0,499). Porcentaje de colágeno tipo I: para los quistes fue de 37,8±19,2 %, mientras que para granulomas fue de 33,8±23,3 %, sin diferencias estadísticas significativas (p=0,704). Se observó una correlación negativa moderada para el infiltrado inflamatorio (R=0,637) y una correlación positiva baja para fibrocitos/fibroblastos (R=0,121), en relación a la cantidad de colágeno tipo I. Medición del área de las lesiones periapicales: el promedio total de las lesiones fue de 10,7±5,0 mm2, siendo el mayor tamaño un quiste de 18,1 mm2 y el menor un granuloma de 5,2 mm2. El análisis histológico permite realizar un diagnóstico diferencial de lesiones con características similares y así definir el tratamiento más adecuado.


Apical periodontitis is an inflammatory pathology that affects the periapical tissues of a devitalized tooth. The aim of this study was to histologically and morphometrically characterize lesions of cysts and granulomas using light microscopy. Six biopsies obtained from teeth with indication of exodontia were analyzed. The histological analysis was carried out by means of optical microscopy and microphotographs, with contrast analysis of images and cell count by ImageJ. A description of the histological characteristics was made, observing the cavities surrounded by stratified squamous non-keratinized epithelium and a fibrous capsule composed of fibrocytes, fibroblasts and chronic inflammatory infiltrate; in the granulomas, capillaries, a fibrous capsule of fibrocytes/fibroblasts and a predominantly lymphocytic inflammatory infiltrate were observed. In relation to quantification of the cellular number of inflammatory infiltrate, for cysts itwas of 9.2 cel / 10000 mm2, while for granulomas it was 20.8 cel / 10000 mm2, without significant statistical differences between both (p = 0.654). The quantification of the fibrocyte / fibroblast cell number was, for cysts, 15.4 cells / 10000 mm2, while for granulomas it was 18.5 cells / 10000 mm2, without significant statistical difference (p = 0.499). With respect to the percentage of collagen type I, for the cysts was 37.8 ± 19.2%, while for granulomas it was 33.8 ± 23.3%, without significant statistical differences (p = 0.704). A moderate negative correlation was observed for the inflammatory infiltrate (R = 0.667) and a low positive correlation for fibrocytes / fibroblasts (R = 0.121), in relation to the amount of type I collagen. Measurement of the area of the periapical lesions: the total average of lesions were 10.7 ± 5.0 mm2, the largest being a cyst of 18.1 mm2 and the smallest a granuloma of 5.2 mm2. The histological analysis allows to make a differential diagnosis of lesions with similar characteristics and thus define the most appropriate treatment.

RESUMO

Resumen: Introducción: Las lesiones periapicales crónicas producen defectos óseos en la zona apical del diente comprometido. La terapia estándar requiere de una osteotomía, remoción del ápice, un profuso curetaje para remover el tejido infectado y granulomatoso, dejando un defecto óseo. Reporte de casos: Dos pacientes con lesiones periapicales fueron sometidos a una apicectomía donde se les colocó como relleno óseo plasma rico en fibrina. El tratamiento fue efectivo, ya que en 30 días se observó radiográficamente una zona radiopaca sugiriendo una formación ósea. Conclusión: La utilización de plasma rico en fibrina para rellenos óseos después de cirugías paraendodónticas podría ser una buena alternativa a los rellenos óseos comerciales por tener propiedades óseo-inductoras.


Abstract Introduction: Chronic periapical lesions cause bone defects in the apical area of compromised teeth. Standard therapy requires osteotomy, apex removal and profuse curettage to remove granulomatous and infected tissue, thus leaving a bone defect in its wake. Report of two cases: Two patients with periapical lesions were subjected to apicoectomy procedure where fibrin-rich plasma was placed as bone filling. Treatment was effective, since after 30 days a radio opaque area was radiographically observed, suggesting bone formation. Conclusion: Use of fibrin-rich plasma as bone filling after paraendodontic surgeries could represent a suitable alternative to commercial bone fillings, due to its bone induction properties.
