Introduction: The purpose of the present study was to investigate the incidence of canine impaction &transmigration in Kanpur Orthodontic population.

Materials & Methods: A retrospective study was designed in which records (dental casts, OPG, IOPA) of consecutive 2730 patients who visited department of Orthodontics, Rama Dental College, Hospital & Research Centre, were evaluated.

Results: The overall incidence of canine impaction was 7.2%. The number of patients with maxillary canine impaction was 125 (50 male & 75 female, incidence 4.57%) and mandibular canine impaction was 27 (male 12 & female 15, incidence 0.98%) and with both maxillary & mandibular canine impaction was 15 (male 6 & female 9, incidence 0.54%). The incidence of mandibular canine transmigration in our study was found to be 0.219%.

Conclusion: The overall incidence of canine was found to be 7.2%.The incidence of maxillary canine impaction was found to be 4.57%.The incidence of mandibular canine impaction was found to be 0.98%.The incidence of mandibular canine transmigration in our study was found to be 0.219%. No case of maxillary canine transmigration was found

Fibrous dysplasia belongs to a group of fibro-osseous lesions in which the normal bone is replaced by cellular fibrous connective tissue stroma. It is considered as a developmental hamartomatous lesion with cases occurring below the age of puberty. It is characterised by a blend of fibrous and osseous elements in the region. It is a lesion of unknown etiology, uncertain pathogenesis, and diverse histopathology. With an incidence of 1:4000-1:10,000 it seems to be a rare disease. It represents approximately 2.5% of all bone lesions and about 7% of all benign bone tumors. Fibrous dysplasia can occur as monostotic form in which single bone is affected and polyostotic form where multiple bones are involved. Majority of the cases reported are monostotic form with predominant site of involvement being craniofacial skeleton. Polyostotic forms are often associated with MaCune Albright syndrome, Jaffe−Lichtenstein syndrome and Mazabraud syndrome. This report describes a case of fibrous dysplasia of a thirteen year female patient who had unusual presentation involving right mandible. The clinical findings, radiological findings and treatment have been discussed.

Giant cell formation forms an important concept in understanding etiopathogenesis of various oral pathologies. Till date numerous concepts have been proposed to elucidate their pathogenesis. However, a consensus is yet to be developed. In the quest to explore all the possible theories related to their formation, the authors realized that till date there is no single literature piece explaining the concepts. Also, the theories have been published in very old papers which are difficult to access by the students interested in learning more about the topic. Hence this compendium is an effort by the authors to simplify the access and explanation of this topic for the students and other researchers.

This case report presents the treatment of a 15-year-and-4-month-old girl with skeletal Class II division 1, mandibular retrusion, increased over jet, deep bite, and convex profile. The treatment plan involved forward movement of the mandible and the mandibular teeth to reduce the increased over jet using the Forsusfatigue-resistant device (FRD) appliance, semi-rigid fixed functional appliance. It is used most for treating Class II patients with retrognathic mandible.

The use of FRD appliance at appropriate time can result with significant changes in the facial profile and dentition, and the results can be maintained at the long-term follow-up periods.

Desquamative gingivitis is characterized by erythematous, epithelial desquamation, erosion of the gingival epithelium, and blister formation on the gingiva. It is a clinical feature of a variety of diseases or disorders. Most cases of desquamative gingivitis are associated with mucocutaneous diseases, the most common ones being lichen planus, mucous membrane pemphigoid, and pemphigus vulgaris. Proper diagnosis of the underlying cause is important because the prognosis varies, depending on the disease. This case report presents an atypical case of desquamative gingivitis on hard palate.
