Non-syndromic multiple impacted supernumerary teeth with peripheral giant cell granuloma.

Peripheral giant cell granuloma (PGCG) is a relatively frequent benign reactive lesion of the gingiva, originating from the periosteum or periodontal membrane following local irritation or chronic trauma. PGCG manifests as a red-purple nodule located in the region of the gingiva or edentulous alveolar margins. The lesion can develop at any age, although it is more common between the second and third decades of life, and shows a slight female predilection. PGCG is a soft tissue lesion that very rarely affects the underlying bone, although the latter may suffer superficial erosion. A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. These teeth may be single, multiple, erupted or unerupted and may or may not be associated with syndrome. Usually, they cause one or the other problem in eruption or alignment of teeth, but may also present without disturbing the normal occlusion or eruption pattern. Management of these teeth depends on the symptoms. Presented here is a case of PGCG in relation to the lower left permanent first molar with three supernumerary teeth in the mandibular arch but no associated syndrome.

Peripheral odontogenic fibroma: A case report and review.

Odontogenic tumors mainly occur as intraosseous growths but sometimes may present in a peripheral location on the gingiva where they are referred to as peripheral odontogenic tumors (POTs) which are a rare entity, the most common of them being the peripheral odontogenic fibroma that is an otherwise uncommon, slowly growing, benign odontogenic neoplasm of the periodontal soft tissues. In fact, peripheral odontogenic fibroma is the only POT that is more frequent than its central counterpart. Although considered to be with a potential to recur after excision, the actual recurrence rate is not known due to paucity of literature. This paper presents a case report along with review of the available literature and reinforces the importance of patient follow-up in addition to radiographic and histological examination of seemingly innocuous gingival exophytic lesions.

Clinical evaluation of correction of pathologic migration with periodontal therapy.

OBJECTIVE: there is a paucity of clinical evidence regarding the amount and frequency of repositioning of pathologically migrated teeth after conventional periodontal treatment. The present study was carried out to find and relate these two parameters of periodontal success with severity of migration. METHOD AND MATERIALS: a total of 45 subjects with a history of recently formed diastema or noticeable increase in already existing diastema were selected. Twenty-nine patients with 76 diastema sites participated in the study (16 patients were lost to follow-up). Repositioning was assessed by measuring the sites on study models obtained at baseline, reevaluation at 6 weeks after nonsurgical periodontal therapy, and 4 months after surgery. RESULTS: after nonsurgical therapy, 65.78% of sites demonstrated some degree of repositioning, while 7.89% closed completely. Four months after surgical treatment, 32.30% of sites showed complete repositioning and 47.69% of sites showed an additional partial repositioning. This corresponds to a 79.99% rate of positive responses to therapy. When sites measuring ⋜ 1 mm were considered, 65.38% showed complete closure and 96.15% demonstrated positive response to therapy. CONCLUSION: the findings suggest that there is an inverse relationship between the severity of migration and amount (as well as frequency) of repositioning. The results emphasize the importance of early diagnosis in the successful treatment of pathologic migration to prevent more complex and time-consuming orthodontic and prosthodontic procedures.
