Evaluation of relationship between dental caries, diabetes mellitus and oral microbiota in diabetics.

Background: Diabetes mellitus is a metabolic disease leading to abnormal fat, carbohydrate and protein metabolism. Reduced salivary flow rate caused by hyperglycemia is characteristic mainly for periods of poor metabolic control of diabetes, thereby facilitating the growth of aciduric bacteria and caries-lesion development. The objective of our study was to evaluate the effects of diabetes mellitus on dental caries micro-organisms responsible for caries.

Malignant fibrous histiocytoma of maxillary alveolar ridge extending to the hard palate.

Malignant fibrous histiocytoma (MFH) is the most common soft-tissue sarcoma occurring in adults. This entity was first described by O'Brian and Stout in 1964. Apart from the soft-tissues, this tumor has been reported to occur in all other parts of the body including bone.

Benign fibrous histiocytoma of the maxilla: a case report and review of literature.

Benign fibrous histiocytoma (BFH) is a mesenchymal tumor which commonly affects the skin of extremities. Histologically, BFH of soft tissues and bone shows similar features, but BFH of the bone is rare with less than 100 cases reported worldwide and usually it involves tibia, femur, and pelvic bone. As far as the oral cavity is concerned, majority of the BFHs are found in the soft tissues of the buccal mucosa, gingiva, lower and upper lips, soft palate, and floor of the mouth.

An unusual occurrence of epidermoid cyst in the buccal mucosa: a case report with review of literature.

Intraoral dermoid and epidermoid cysts are rare and account for less than 0.01% of all the cysts in the oral cavity. A large majority of the same arise in the floor of the mouth and infrequently in other sites.

Osteosarcoma of mandible.

Osteosarcomas are malignant neoplasms of the bone which commonly affect the long bones. The involvement of the jaws are rarely noticed. These neoplasms often shows a typical clinical behaviour as well as varied radiological appearances.

Multiple bilateral supernumerary mandibular premolars in a non-syndromic patient with associated orthokeratised odontogenic cyst- A case report and review of literature.

Multiple supernumerary teeth are very rare, accounting for less than 1% of cases. They are commonly associated with syndromes like Gardner's syndrome and cleidocranial dysostosis and cleft lip and palate. Non-syndromic multiple supernumerary teeth have a predilection to occur in the mandibular premolar region.

Orthodontic management of an impacted maxillary incisor due to odontoma.

Odontomas are a heterogeneous group of jaw bone lesions, classified as odontogenic tumors which usually include well-diversified dental tissues. Odontomas are the most common type of odontogenic tumors and generally they are asymptomatic. Two types of odontomas are described: compound and complex based on either the appearance of well-organized tooth-like structures (compound odontomas) or on a mass of disorganized odontogenic tissues (complex odontomas).

Comprehensive management of a rare carcinoma ex pleomorphic adenoma of the lacrimal gland with a modified lateral orbitotomy access osteotomy. A case report.

Background: Complete management of extraconal ocular tumors may require the joint efforts of a maxillofacial surgeon to provide access and an ophthalmic surgeon to completely excise the lesion. Pleomorphic adenoma is the most common benign tumor of the lacrimal glands, representing around 12% of the lacrimal fossa lesions. They may however undergo malignant changes.

Effect of retraction materials on gingival health: A histopathological study.

Background: Gingival retraction methods are used in dentistry for impressions of subgingival crown margins, such as, mechanical, chemical, chemicomechanical, and surgical. These methods may injure the gingival sulcular epithelium. Hence, the present study is carried out to evaluate the effect of different retraction materials, such as, Expasyl, Magic Foam Cord, and impregnated retraction cord on the gingival sulcular epithelium.
