Basaloid squamous cell carcinoma (BSCC) is a distinct variant of conventional squamous cell carcinoma (SCC), predominantly localized in the upper aerodigestive tract. In the head and neck region, the tumor has a strong predilection for extra-laryngeal sites, such as the base of the tongue, tonsil, hypopharynx and supraglottic larynx. BSCC has well-defined histological features, characterized by nesting, lobular and trabecular arrangement of basaloid cells. Central comedonecrosis within the cell nests, cells with nuclear palisading and high-grade dysplasia in overlying mucosa are the main characteristics. The tumor is considered to be highly aggressive and often presents itself as an advanced stage lesion, thus demanding early diagnosis and prompt treatment. We here report a case of 72-year-old male diagnosed with BSCC involving the right tonsillar region.

Hemangiopericytoma (HPC) is a rare tumor of uncertain malignant potential. Stout and Murray described HPC as “vascular tumor arising from Zimmerman's pericyte” in 1942. The World Health Organization (WHO) reclassified HPC as a fibroblastic/myofibroblastic tumor, after further characterization. HPC is found mostly wherever there is increased vascularity seen. The incidence of the tumor in head and neck area is only 15%, mostly seen in adults. We report here a case of HPC of a 22-year-old female, who presented to our department with a tender swelling in maxillary anterior region and the mass was well-circumscribed, sessile and soft on palpation. The skin over the tumor was intact and normal. The tumor was completely removed with wide surgical resection. The histopathological staining supported the diagnosis of HPC, this was further confirmed by immunohistochemistry (IHC) in which CD99 showed strong positivity.

Although the flapless technique of endosseous implant placement had statistically significant less PD, bone loss, and pain than the flap technique, the difference was found to have uncertain clinical significance.

This case report describes a technique used to treat smooth surface white spot lesions microinvasively. It is based on the infiltration of an initial enamel caries lesion with low-viscosity light-curing resins called infiltrants. The surface layer is eroded and desiccated, followed by resin infiltrant application. The resin penetrates into the lesion microporosities driven by capillary force and is hardened by light curing. Infiltrated lesions lose their whitish appearance and look similar to sound enamel. Additionally, the treatment prevents lesion progression. This technique might be an alternative to microabrasion and restorative treatment in treating of white spot lesions of esthetically relevant teeth.

Background:Multiple approaches have been used to replace lost, damaged or diseased gingival tissues. The connective tissue graft (CTG) procedure is the golden standard method for root coverage. Although multiple sites often need grafting, the palatal mucosa supplies only a limited area of grafting material. To overcome this limitation, expanded mesh graft provides a method whereby a graft can be stretched to cover a large area. The aim of this study was to evaluate the effectiveness and the predictability of expanded mesh CTG (e-MCTG) in the treatment of adjacent multiple gingival recessions.Materials and Methods:Sixteen patients aged 20–50 years contributed to 55 sites, each site falling into at least three adjacent Miller's Class 1 or Class 2 gingival recession. The CTG obtained from the palatal mucosa was expanded to cover the recipient bed, which was 1.5 times larger than the graft. Clinical measurements were recorded at baseline and 3 months, 12 months postoperatively.Results:A mean coverage of 1.96 mm ± 0.66 mm and 2.22 mm ± 0.68 mm was obtained at the end of 3rd and 12th month, respectively. Twelve months after surgery a statistically significant increase in CAL (2.2 mm ± 0.68 mm, P < 0.001) and increasing WKT (1.75 ± 0.78, P < 0.001) were obtained. In 80% of the treated sites, 100% root coverage was achieved (mean 93.5%).Conclusions:The results of this study demonstrated that multiple adjacent recessions were treated by using e-MCTG technique can be applied and highly predictable root coverage can be achieved.

Implant related prosthesis has become an integral part of rehabilitation of edentulous areas. Single stage implant placement has become popular because of its ease of use and fairly predictable results. In this paper, we present a series of cases of single stage implants being used to rehabilitate different clinical situations. All the implants placed have been successfully restored and followed up for up to one year.

Dens Invaginatus (DI) is a rare developmental anomaly, which presents as an infolding of enamel and dentine extending into the pulp chamber and sometimes into the root. The aim of this case report was to describe its radiographic findings, to emphasize the inexplicable morphology. Considering the likelihood of an early pulpal involvement and the chronic periapical lesions often associated with this anomaly without any clinical symptoms, dens invaginatus is clinically significant. Difficulties are encountered during the endodontic treatment, owing to the complex root canal anatomy. Therefore, a proper diagnosis and evaluation of the anomaly is essential to save the involved tooth.
