Neurofibroma is a benign tumor of the peripheral nervous system affecting Schwann cells as well as neural sheath cells. It is usually considered as a component of Von Recklinghausen's disease, but solitary lesions have also been reported, though not very frequently. It is mostly reported on the skin.

Pycnodysostosis is a rare autosomal recessive condition caused by the mutation of CTSK gene. CTSK regulates the activity of Cathepsin K which is responsible for osteoclast-mediated bone resorption. This mutation causes the bones to become dense, sclerotic, brittle, and thus, prone to fracture.

One such effect is traumatic injuries secondary to chewing inanimate objects like pencils. Following trauma, the lead of the pencil has been reported to embed in the soft tissue of the oral cavity, appearing as a grayish pigmentation (graphite tattoo).

Objective: To evaluate the efficacy of 3% sodium hypochlorite (NaOCl), 17% ethylenediaminetetraacetic acid (EDTA), calcium hydroxide [Ca (OH)2], and 2% chlorhexidine in various combinations on Candida albicans in root canals for 48 h and 10 days.
Materials And Methods: In this in vitro study, 95 extracted teeth were instrumented. MTCC 183 strain of C.
Talon cusp (TC) and dens invaginatus (DI) are relatively rare developmental anomalies which affect the shape of teeth. TC is an additional cusp that projects predominately from the lingual surface of anterior teeth. DI is a deep surface invagination of the crown or root which is commonly detected on routine radiographic examination.

Objectives: The purpose of this study was to find correlation between vertical dimension of occlusion (VDO) and interpupillary distance (IPD).
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.

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.

Materials And Methods: A cross-sectional study was conducted on 400 dentate subjects comprising of 200 males and 200 females. Anthropometric measurements of VDO, length of index finger, length of little finger, and distance from tip of thumb to tip of index finger of right hand were recorded clinically using modified digital vernier caliper.
Dentigerous cysts are the most common type of developmental odontogenic cysts arising from the crowns of impacted, embedded, or unerupted teeth. They constitute about 20% of all epithelium-lined cysts of the jaws. The teeth involved most often are mandibular third molar and maxillary canines.

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.

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).
