    Papillary cystadenocarcinoma (CAC) a rare malignant salivary gland tumor which commonly arises in the major glands, mainly the parotid, and less frequently in the minor salivary glands. Localization in the sublingual salivary gland is very rare. The authors present a case of papillary CAC originating from the right sublingual gland in a 78-year-old female. A review of the literature revealed only 3 previously published detailed cases (in addition to 2 cases as part of larger series) of papillary CAC of the sublingual gland. The salient demographic, clinical, and histopathologic findings of...

    A case of periradicular surgery: apicoectomy and obturation of the apex, a bold act

    Lino Lucio Locurcio , Rachel Leeson
    This paper reports a case of a recurrent periapical cyst treated with enucleation of the lesion, apicoectomy, and root end obturation on a lower left first molar. In the case of conventional root canal treatment failure, non-surgical retreatment is the preferred option in most of the cases. Several factors such as a complex root canal system or previous procedural accidents may impede the success of non-surgical retreatment. The authors have performed root-end resection and preparation under local anesthesia on a lower left first molar; The root canal filling is placed within the new cavity...

    Stem cell markers as a resource to predict prognosis of betel quid induced oral squamous cell carcinoma: an immunohistochemical investigation

    Primali Jayasooriya , Champika Fernando , Anura Suraweera , Upul Dissanayake
    Aim: The study was to correlate the survival of a group of Sri Lankan betel quid induced oral cancer patients with the expression patterns of five cancer stem cell (CSC) markers namely ALDH1, Sox-2, Bmi-1, C-met, and Oct-4. Methods: Archival tissues of 140 oral squamous cell carcinomas (OSCCs) were stained with CSC markers, ALDH1, Sox-2, Bmi-1, C-met, and Oct-4. Survival analysis was performed with SPSS version 20, using Kaplan-Meier survival curves and significance with chi-square test and Breslow’s (generalized Wilcoxon) test. Results: Immunohistochemical investigations revealed 55.7%,...

    Effect of processing technique and coping thickness on fracture resistance of lithium disilicate copings

    Mohamed H. Riad , Jihan F. Younis , Hanaa H. Zaghloul
    Aim: The purpose of this in vitro study was to determine the optimum margin thickness which allows more conservative tooth preparation, thus giving space for the veneer material and to evaluate the effect of the processing technique on fracture resistance of IPS e.max® copings. Methods: Forty all lithium disilicate copings were divided into 2 equal groups according to the construction technique; twenty copings each (n = 20) per group. Each group was further subdivided into 2 equal subgroups according to the coping margin thickness; 0.5 mm and 0.7 mm (n = 10/subgroup). Two dies were prepared...
