X-rays were taken, and the teeth were decoronated using a diamond disc. The canals were prepared and filled with zinc oxide-eugenol sealer and gutta-percha cones using the late- ral compaction technique. They were left for 24 hours in order to ensure the quite hardening of the filling material. After that, the filling material was removed vertically using a hot plugger up to a depth of 1 or 2mm inside the root canal, dividing by that the teeth into two main groups of 45 teeth each according to the depth of the intra-orifice. Each group was further divided into three sub-groups of 15 teeth each. The intra-orifice of all the teeth was filled with one of the restorative materials. The teeth were coated with varnish except for 1mm around the root canal intra-orifice. Then, they were immersed in methylene blue dye of 2% for five minutes. After that, the teeth were washed under a stream of copious water and left to dry. Longitudinal sections were made in the bucco-lingual direction. The sections were examined under an optical magnifier to measure the linear dye leakage using a millimeter ruler designed by “Autocad 2013” program. Statistical analyses were conducted after collecting the data with p-value <0.05. MTA material was significantly the best in coronal sealing. However, there were significant differences between MTA and composite and between GIC and composite at the depth of 1mm, but no such differences were found at 2mm depth. MTA and GIC offered a higher sealing ability at a depth of 1 and 2 mm, while composite showed the least sealing ability among the materials.

Thirty-four patients with no previous orthodontic treatment participated in the study. Cone beam computed tomography (CBCT) scans were taken. Sagittal sections of the roots were made to evaluate the supporting bone at the labial and the lingual aspects and at three different levels: cervical, middle and apical. Angles of the upper central incisors (U1/U2) with the palatal plane (SPP) were also measured. The palatal apical region had the greatest thickness of bone tissue followed by the palatal middle and the labial apical regions. The lowest thickness was observed on the labial surface, in the apical and in the middle of the root. The thickness of the labial apical region of both upper teeth increased significantly when the angle between the upper central incisors axis and the palatal plane increased (U1: p = 0.012/ r = 0.42 and U2: p = 0.005/ r = 0.46). The thickness of the palatal middle of the root regions for both upper central incisors were significantly higher in males than females (U1: p = 0.005/ average = 1.2 mm for males; U2: p = 0.003/ average = 1.0 mm for males). There was no significant difference in the incisors’ inclination between males and females. The bone tissue thickness in the labial apical region increased when the inclination of the upper central incisors increased. The greatest value of bone tissue amount was in the apical region, whereas the lowest value was in the labial surface in both cervical and middle of the root regions. Males had a higher value than females of bone tissue amount in the palatal middle of the root region at the upper central incisors.

The specimens were randomly divided into 3 groups (n = 15). The first group received a root filling using cold lateral condensation of gutta-percha cones and zinc-oxide eugenol-based sealer.

Smooth muscle neoplasms can be classified into solid leiomyomas, angioleiomyomas (vascular leiomyomas) and epitheloid leiomyomas (leiomyoblastomas). Among these types, the vascular leiomyoma is the most common subtype in the oral cavity. It may appear at any age with the greatest incidence in the 4th and 5th decades of life. The common manifestation is a slow-growing, asymptomatic, submucosal mass. The diagnosis is only possible through histopathological examination requiring special staining. The treatment of choice is the surgical excision and no recurrence is usually seen, though malignant transformation of these tumors has been reported. Hence a thorough examination, knowledge and follow-up must be warranted in this soft tissue tumor. In this article, we present a rare case of an angiomyoma in the right side of the hard palate with description of its clinical, histological and immunohistochemical characteristics. Resume L’angiomyome est defini comme etant une tumeur benigne douloureuse, sous-cutanee ou profonde, composee de faisceaux musculaires lisses matures qui sont entoures et entrelaces par des canaux vasculaires. Les neoplasmes du muscle lisse peuvent etre classes en leiomyomes solides, en angioleiomyomes (leiomyomes vasculaires) et en leiomyomes epithelioides (leiomyoblastomes). Parmi ces types, le leiomyome vasculaire est le sous-type le plus observe au niveau de la cavite buccale. Il peut apparaitre a tout âge avec la plus grande incidence dans la 4eme et la 5eme decennie de la vie. La manifestation commune est une masse sous-muqueuse, asymptomatique, a croissance lente. Le diagnostic n’est possible que grâce a l’examen histopathologique necessitant une coloration speciale. Le traitement de choix est l'exerese chirurgicale; aucune recidive n’est generalement consideree, bien que la transformation maligne de ces tumeurs ait ete decrite.
