ABSTRACT
Hyperdontia or supernumerary teeth in both arches without any syndromic manifestation are extremely rare. Supernumerary teeth are commonly associated with Gardner's syndrome, cleft lip and palate, cleidocranial dysplasia and trichorhinopha-langeal syndrome. Five cases of non-syndromic multiple premolars of maxillary and mandibular arches in Indian patients are presented here. This case series reports three cases with multiple (9 in maximum), bilaterally impacted and erupted supernumerary teeth and two cases with supernumerary premolars in non-syndromic cases from Indian patients. Supernumerary teeth can be present in any region of the oral cavity. Although the occurrence of maxillary para-premolars is rare, radio-logical investigations play a major and decisive role in determining the management of such cases.
ABSTRACT
Various root developmental anomalies like palatoradicular groove (PRG) have been associated with worsening of periodontal condition. The aim of the present case report is to describe the regenerative surgical treatment of periodontal and osseous lesion associated with the subgingival extension of PRG. A 23-year-old female patient reported with pain in upper incisor teeth region. On clinical and radiological examination, a deep endosseous defect was found distal to maxillary right lateral incisor that was etiologically associated with the presence of a PRG. Treatment procedures consisted of: Regenerative periodontal therapy using Guided tissue regeneration (GTR) and hydroxyapatite (HA) bone graft and 2) flattening of the radicular portion of the palatal groove. The clinical examination at 1 year revealed shallow residual probing depth (3 mm) and no increase in gingival recession. The radiographic examination showed reduction in the radiolucency suggesting bone fill. A PRG may serve as a pathway for the development of a periodontal osseous defect. The combination of GTR and HA may be clinically and radiographically efficacious in the treatment of such a defect.
