Periodontal regeneration is now a major challenge in periodontal research and practice. It involves the use of regenerative therapy to restore the defects produced by the defects produced by the disease process. Bone grafting is known to be one such most important regenerative procedures.However, the successful prevention and treatment of periodontitis is contigent upon effective control of the periodontopathic bacteria residing in the various ecological niches of the oral cavity. So, Doxycycline have been incorporated into the allograft to control infection and facilitate healing during and after periodontal therapy.It has the ability to concentrate in the GCF at levels, substantially greater than that in the serum and also binds to the tooth surface to be slowly released in active form, thereby prolonging therapeutic effects.It demonstrates anticollagenolytic and antiproteolytic properties that aid osseous regeneration and also helps in reducing periodontal disease progression.It has also been shown to initiate demineralization on the bone surface layer that results in the release of osteogenic factors such as TGF, IGF& BMP that triggers bone induction

Oral lichen planus is most commonly asymptomatic and gingival lesions of lichen planus such as atrophic, erosive and desquamative lesions, were often found to co-exist with chronic marginal gingivitis. Whether these lesions are benign or malignant, early diagnosis and planned treatment is mandatory to check the menace at the earliest. The use of bio-resorbable membranes had been proposed to regenerate periodontal structures like alveolar bone, periodontal ligament and epithelium. However it has rarely been tried in the management of lichen planus of gingivae. Surgical managememnt of such cases was performed to evaluate the use of bio-resorbable membranes in the management of erosive lichen planus of gingivae

Dental hypersensitivity probably affects most individuals and at times, pain may be so severe that patient believes that his/her dentition is seriously and perhaps irreversibly affected. Iontophoresis i.e. use of desensitizing agents along with electric current has been utilized as a lasting and predictable treatment of dental hypersensitivity. In the recent past, researchers have been trying to manage this problem by surgical means also by re-covering the exposed tooth root surfaces. Present investigation attempted to find out the effects of combining both these treatment modalities to alleviate the menace of hypersensitivity, along with enhancing the patient's esthetics.
