Oligodontia Of Permanent Dentition Research Articles

Prosthodontic rehabilitation of non-syndromic oligodontia case with telescopic prosthesis

Oligodontia is the congenital absence of six or more permanent teeth excluding the third molars. Oligodontia of permanent dentition is a rare occurrence. Preservation of the remaining deciduous dentition in such situations is important for both functional and esthetic rehabilitation of the patient. This case report describes the rehabilitation of a 16 year old male with oligodontia of permanent teeth treated by an interdisciplinary team of Prosthodontist, paedodontist and orthodontist. Endodontic treatment of all the remaining deciduous dentition was done. Vertical dimension of deciduous dentition occlusion was assessed. Full mouth single piece porcelain fused to metal telescopic prosthesis for maxillary and mandibular arch was planned with minimal increase in vertical dimension of occlusion. Telescopic prosthesis provided excellent retention, stability, esthetics and stress equalization on the remaining deciduous dentition. Maintenance of oral hygiene procedures was simplified for the adolescent with the telescopic prosthesis. Preservation of remaining deciduous dentition and fabrication of a telescopic prosthesis in this patient provided an effective aesthetic and functional rehabilitation for the patient.

Occurrence of partial ankyloglossia with isolated oligodontia in permanent dentition: A case report

AbstractAnkyloglossia or tongue-tie is a relatively benign condition that causes difficulties in normal functioning of the tongue due to an anatomic variation in the lingual frenum, leading to the formation of thick and short frenum. This can be corrected with simple surgical procedures. Oligodontia is the developmental absence of six teeth or more, excluding third molars. It can be isolated or non-syndromic and/or can be a part of a syndrome. The present case report describes an 8-year-old boy with a rare occurrence of a combination of ankyloglossia with isolated oligodontia in his permanent dentition with no apparent systemic complications.

Non-syndromic oligodontia in permanent dentition: a rare case report

Objective: Tooth agenesis is one of the most common congenital anomalies seen in humans. Although ab¬sence of one or more teeth is common, absence of multiple teeth is rare. Oligodontia is a rare developmental anomaly, involving agenesis of six or more permanent teeth, excluding the third molars. The reported preva¬lence of oligodontia in permanent dentition is 0.14%. Oligodontia can be presented as an isolated condition or as a part of a syndrome. Discussion: The present case report highlights a unique case of non-syndromic oligodontia, with agenesis of four permanent incisors, left permanent canine and right second premolar in the mandibular arch and its management with a novel fixed functional prosthetic appliance. Conclusion: Prosthetic rehabilitation is an urgent need for these kind of patients so that they do not suffer from mastica¬tory and esthetic problems which can eventually lower the self esteem of individuals.

Non-syndromic Oligodontia in Permanent Dentition of Monozygotic Twins: Report of a Rare Case

To report a case of non-syndromic oligodontia involving 26 permanent teeth in monozygotic twin sisters and to discuss the possible genetic etiology, inheritance pattern and associated dental anomalies of this condition. Hypodontia constitutes one of the most common developmental anomalies in humans and is defined as developmental absence of one or more teeth with reported prevalence of 1.6 to 9.6% in the permanent dentition. Oligodontia is defined as agenesis of six or more teeth excluding third molars. This article describes a case of non-syndromic oligodontia involving 26 permanent teeth in monozygotic twin sisters. The twins had positive family history of hypodontia in their paternal grandmother, parental consanguinity (first cousin) and similarity in pattern of oligodontia. Root formation of permanent maxillary first molars and central incisors was delayed in both the twins. This article reports a case of non-syndromic oligodontia in permanent dentition of monozygotic twins. Possible genetic etiology, inheritance pattern and associated dental anomalies are discussed. Strong genetic link associated with oligodontia help the dentist to know the possibility of its occurrence in other family members and in future generations.
