ABSTRACT
This case report described the endodontic treatment and decompression of an extensive lesion in the anterior region of the mandible, detected during clinical and radiographic examination, in a patient with a complaint of slight tenderness to palpation in the area of mandibular right lateral incisor and canine. These teeth had been accessed without proper clinical evaluation, and their pulp tissues were exposed. The periodontal tissues were healthy, with no signs of inflammation or fistula. On radiographic examination, a radiolucent lesion with well-defined borders was seen extending from the distal root of mandibular left second premolar to the mesial root of mandibular right second premolar. Central and lateral mandibular left incisors were unresponsive to thermal pulp testing and exhibited coronal discoloration, consistent with a diagnosis of pulp necrosis. Due to persistent discharge from the root canal system during endodontic procedures despite application of intracanal medicament (calcium hydroxide paste), the decision was made to biopsy and decompress the lesion and conclude endodontic treatment. Histopathologic examination revealed a periapical granuloma. After endodontic treatment of the involved teeth, at 4-year clinical and radiographic follow-up, the affected region was almost completely repaired.
ABSTRACT
O torus palatino é uma alteração de desenvolvimento comum, localizada na linha média do palato duro. Sua etiologia é incerta, podendo ser associado alterações funcionais, fatores genéticos e características raciais. Sua incidência varia de acordo com grupos étnicos, idade e geralmente acomete o sexo feminino. Normalmente esse nódulo ósseo intra oral não apresenta sintomatologia dolorosa, todavia a sua remoção é freqüentemente indicada quando há trauma recorrente, interferência nos processos de fonação, deglutição, mastigação, no posicionamento normal da língua, ou para correção de deformidades ósseas que prejudiquem a adaptação de prótese...
The palatine torus is a usual developmental disturbance, located in the midline of the hard palate. Its etiology is uncertain and may be associated with functional changes, genetic factors and racial characteristics. Its incidence varies according to ethnic groups, age and usually affects females. Normally this intra-osseous oral nodule presents no painful symptoms, but its removal is often required when there is recurrent trauma, interference in the processes of speech, swallowing, chewing, in the normal positioning of the tongue, or to correct bone deformities that affect the adaptation of prosthesis...
