ABSTRACT

BACKGROUND: Polymorphous low-grade adenocarcinoma (PLGA) is a slow growing malignant tumor of minor salivary glands and is generally of indolent nature. However, according to the most recent WHO Classification of Salivary Gland Tumors (2017), the cancer is classified as Polymorphous AdenoCarcinoma (PAC). PAC presents as a less aggressive tumor, though it could on rare occasions demonstrate distant metastasis. Case Presentation. A 47-year-old man who was referred by a private practitioner for a CBCT scan in reference to a proliferative soft-tissue growth in the hard palate. The growth was mild and tender and there was Grade III mobility in relation to all the maxillary teeth. Panoramic radiograph taken previously had revealed evidence of alveolar bone loss in relation to the maxillary teeth and was inconclusive of any other findings. The CBCT scan revealed evidence of moth-eaten appearance of maxilla with destruction of medial and lateral walls and floor of maxillary sinus. There was also evidence of involvement of right eustachian tube, ethmoidal wall, and nasopalatine canal. An intraosseous malignancy of the palate was suspected, and a total maxillectomy was performed. The tissue sample was sent for histopathological assessment wherein changes diagnostic for polymorphous low-grade adenocarcinoma of the palate were observed. CONCLUSION: PAC is a distinct, yet commonly occurring, minor salivary gland tumor with varied clinical and histologic appearance. This case report highlights the importance of CBCT in diagnosing the intraosseous involvement of such tumors which can help shed some light in enhancing our knowledge about the minor salivary gland malignancies like PAC.

ABSTRACT

@#Dermoid cysts are rare developmental benign lesions that arise as a result of ectodermal differentiation of multipotent cells. Histologically the cysts are classified as dermoid, epidermoid and teratoid cysts depending on the presence of adnexal structures and derivatives of germ layers. When dermoid cysts appear in the floor of the mouth they can cause difficulty in deglutition and respiration. The differential diagnosis of dermoid cyst could be infection, ranulaor tumor. Intraoral or extra oral approach for enucleation is the method of treatment. Dermoid cysts have a good prognosis with low malignancy and recurrence rate. A case report of a dermoid cyst in the floor of the mouth is presented in this paper along with clinical, histopathological evaluation and the treatment.

ABSTRACT

Epidermolysis bullosa (EB) is an inherited disorder, which is characteristically presented as skin blisters developing in response to minor injury. Junctional variety of EB is also associated with enamel hypoplasia. Amelogenesis imperfecta presents with abnormal formation of the enamel both in deciduous and permanent dentition. This article describes a previously unreported case of Amelogenesis imperfecta with complete loss of enamel in a young female patient with EB.

ABSTRACT

Data from recent epidemiological studies provide overwhelming evidence that areca nut is the main etiological factor for oral submucous fibrosis (OSF). It is logical to hypothesize that the increased collagen synthesis or reduced collagen degradation is the possible mechanism in the development of the disease. There are numerous biological pathways involved in the above processes and it is likely that the normal regulatory mechanisms are either down regulated or up regulated at different stages of the disease. The copper content of areca nut is high and the possible role of copper as a mediator of fibrosis is supported by the demonstration of the up regulation of lysyl oxidase in OSMF biopsies. The aim of this article is to emphasize that the incorporation of copper into the areca nut is through the Bordeaux mixture, which is sprayed as a fungicide on areca plantations in regions with scheduled monsoons and of which copper sulfate is an important constituent.

ABSTRACT

UNLABELLED: Pregnancy is a period of both joy and anxiety in a woman's life and is characterized by various physiological changes in her body brought about by the circulating female sex hormones. The oral cavity is also the seat of changes and these physiologic changes of pregnancy need to be addressed while managing the pregnant woman in the dental clinic. The main goal is to minimize the occurrence of any complications that might harm the mother-to-be and/or the unborn child. Preventive, emergency, and routine dental procedures are all deemed suitable during various phases of pregnancy, with some treatment modifications and initial planning. CLINICAL RELEVANCE: The dentist should be in a position to manage pregnant women in clinical practice effectively.

ABSTRACT

Talon cusp is a dental anomaly also known as an eagle's talon. It is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. The exact etiology is unknown. The inci-dence of talon cusp is less than 6%. Commonly involved teeth are maxillary incisors, usually unilateral but in some instanc-es bilateral. The classical radiographical feature of talon cusp is double teeth appearance. The anomaly has been reported to be unusual in the mandibular dentition. This article reports an unusual case of talon cusp of permanent mandibular central incisors.

ABSTRACT

Odontogenic keratocyst (OKC) is the cyst arising from the cell rests of dental lamina. It can occur anywhere in the jaw, but commonly seen in the posterior part of the mandible. Radiographically, most OKCs are unilocular when presented at the periapex and can be mistaken for radicular or lateral periodontal cyst. When the cyst is multilocular and located at the molar ramus area, it may be confused to ameloblastoma. Lots of cases have been reported in the literature where OKC is associated with the nonvital tooth. So trauma could be one of the reasons in inducing this cyst. In our case, it was in the anterior region at the periapex of nonvital tooth having traumatic occlusion. Hence, the diagnosis of radicular cyst was made and endodontic treatment was done.

ABSTRACT

Ellis-van Creveld syndrome is a rare congenital genetic disorder having autosomal recessive inheritance. It is a syndrome affecting the Amish population of Pennsylvania in USA with prevalence rate of 1/5,000 live at birth. In non-Amish population, the birth prevalence is 7/1,000,000. The syndrome is characterized by bilateral postaxial polydactyly of the hands, chondrodysplasia of long bones resulting in acromesomelic dwarfism, ectodermal dysplasia affecting nails as well as teeth and congenital heart malformation. There were very rare reports of this syndrome in dentistry. The present case focuses on the striking and constant oral findings of these patients, which are the main diagnostic features of this syndrome. Since the oral manifestations affect the esthetic, speech, and jaw growth of the child, the dentists have an important role to play in proper management of such case.
