ABSTRACT
Stafne first described the term "Stafne bone defects" (SBDs) in 1942. These are unilateral, asymptomatic, well-defined radiolucent lingual bony defects located at the posterior region of the mandible below the inferior alveolar canal. It is most commonly seen in the posterior region, whereas it is relatively rare in the anterior region. This anterior variant of SBD is often misdiagnosed as any other odontogenic cyst, and hence advanced imaging techniques should be followed to identify it at the earliest. Due to the lower prevalence of this entity, only a handful of cases have been documented for the anterior variant of SBD. In this paper, we have thus documented the rare variant of SBD in the anterior region.
ABSTRACT
Schwannoma or neurilemmoma is a benign, slow-growing nerve sheath tumor arising from Schwann cells of the cranial, peripheral or autonomic nerves. Approximately 25%-40% of schwannomas occur in the head and neck region. Occurrences of intraoral schwannomas are rare with reported prevalence being 1%. Intraorally, schwannomas occur in the tongue, palate, buccal mucosa, lips and gingiva. This article provides an insight into a rare case of palatal schwannoma with literature review.
ABSTRACT
Aloe vera (Aloe barbadensis) is a plant that belongs to Liliaceae family. The name Aloe derives from the Arabic word "Alloeh" meaning shining bitter substance while "vera" in Latin means true. It contains various minerals and vitamins. It has got various properties such as immunomodulatory, antiviral and antiinflammatory in nature. A. vera can play a significant role in dentistry in treatment of lichen planus, oral submucous fibrosis, recurrent aphthous stomatitis, alveolar osteitis, periodontitis, etc.
ABSTRACT
Radiography can play an important part in forensic odontology, mainly to establish identification. This may take the precise form of comparison between antemortem and postmortem radiographs. Radiographs may also be taken to determine the age of a minor victim and even help in the assessment of the sex and ethnic group. Comparable radiographs are an essential factor to confirm identification in a mass disaster.
ABSTRACT
Oral mucosal melanoma is a rare malignancy with the tendency to metastasize and locally invade tissues more readily than other malignant tumor of the oral cavity. It occurs approximately four times more frequently in the oral mucosa of the upper jaw usually on the palate or alveolar gingiva. The chameleonic presentation of malignant melanoma, its asymptomatic condition, rarity of the lesion, poor prognosis and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health care provider. Herein we report a rare and interesting case of oral malignant melanoma of the maxillary anterior gingiva, which was clinically and histopathologically diagnosed with a brief review of literature, has been discussed.
ABSTRACT
Most of the Biomedical applications use dedicated processors for the implementation of complex signal processing. Among them, sensor network is also a type, which has the constraint of low power consumption. Since the processing elements are the most copiously used operations in the signal processors, the power consumption of this has the major impact on the system level application. In this paper, we introduce low power concept of transistor stacking to reduce leakage power; and new architectures based on stacking to implement the full adder and its significance at the digital filter level for QRS detector are implemented. The proposed concept has lesser leakage power at the adder as well as filter level with trade-off in other quality metrics of the design. This enabled the design to be dealt with as the low-power corner and can be made adaptable to any level of hierarchical abstractions as per the requirement of the application. The proposed architectures are designed, modeled at RTL level using the Verilog-HDL, and synthesized in Synopsys Design Compiler by mapping the design to 65 nm technology library standard cells.
