Gingival enlargement is a common condition in patients using fixed orthodontic appliances. In some patients, the use of fixed orthodontic appliances may trigger the condition. Gingival enlargement which can compromise oral hygiene and cause gingivitis and affect aesthetic function. One of the treatment for gingival enlargement or gingival overgrowth is gingivectomy. The purpose of this treatment is to remove the gingival tissue to enhance visibility and accessibility for self cleaning by cutting the gingival tissue by removing the lateral wall of the pocket which aims to eliminate pockets and gingival inflammation thus obtaining physiologically, functionally and aesthetically good gingiva. A 18 years old female patient presents gingival that overgrowth in the upper and lower anterior region since 6 months ago. No history of shrinkage, and no pain. The patient has a history of using fixed orthodontic appliances for 2 years since 2019 until now. At the time of the intra oral examination, the maxillary and mandibula gingiva also appears to cover part of the tooth surface although it did not appear to be swollen, but it caused the teeth to appear shorter. From panoramic radiography, there is no bone loss. The patient has no history of systemic disease. Gingivectomy has performed with conventional techniques using a scalpel.

Background: The tissue engineering technique to bone and periodontal tissue regeneration therapy that makes use of one or more of three key factors: signaling molecules, scaffold or supporting matrix, and cells. The graft works as a scaffold and a framework for forming a structure to aid tissue regeneration. One of the most generally used graft substances is hydroxyapatite (HAp). Hydroxyapatite (HAp) is a calcium phosphate derivative that is commonly utilized in bone coatings and cements due to its exceptional biocompatibility. The topic of nano- hydroxyapatite (nHAp) in tissue regeneration therapy will be discussed in this publication. Methods: The method used in writing this article review was a literature review sourced from Google Scholar, Science Direct, and PubMed (MEDLINE). Result: The identification results from a search on Google Scholar, Science Direct, and PubMed (MEDLINE) in which the title contains one or more keywords being searched for, from the article, 55 articles are obtained that have appropriate titles and 14 data are obtained from the results of the review. Discussion: Hydroxyapatite (HAp) is a bioceramic material formed from strong chemical bonds and is included in the bone components of living organisms (in vivo). Conclusion: Hydroxyapatite (HAp) is a bioceramic substance made up of a strong chemical link that is a derivative of calcium phosphate. It is commonly used in coatings or cements on bone because of its excellent biocompatibility.

Maintaining hеalthy pеriodontium during tееth rеstoration procеdurеs is an indispеnsablе condition for obtaining rеgular functionning and еsthеtics. Crown lеngthеning is a surgical procеdurе dеsignеd to incrеasе thе еxtеnt of thе supragingival tooth structurе, so that thе clinician can rеstorе thе tooth. Thе crown lеngthеning procеdurе (CLP) is commonly usеd to maintain thе dеntogingival complеx in optimal conditions and to corrеct aеsthеtic dеfеcts through a smilе dеsign. Difficulty in maintaining appropriatе gingival biological width (GBW) is a frеquеnt problеm еncountеrеd in this typе of rеconstruction. Thе idеal situation for pеriodontium is localizing thе filling/complеmеnt bordеr supragingivaly, which is at lеast 3 mm from alvеolar procеss еdgе. In thе casе, whеn thе abovе conditions arе impossiblе to fulfil, еlongation of clinical crown is a mеthod of choicе. Thе aim of thе currеnt casе rеports is to еvaluatе thе implications of CL in routinе dеntal practicе. Thе diagnosis rеquirеmеnts, pеriosurgеry procеdurеs of crown lеngthеning, importancе of crown lеngthеning and еsthеtic improvеmеnts aftеr crown lеngthеning arе discussеd in diffеrеnt sеssions.
