Oligodontia, although rare, may have significant impact on the quality of life of those affected with it. Provision of restorative treatment for these patients can be very challenging and demanding for clinicians, especially during the active growth phase. Nevertheless, the dental needs of these patients are real and should be addressed appropriately. The present case report described a restorative rehabilitative plan and execution of different restorative treatment modalities in a 14-year-old patient with oligodontia. The challenges faced in the provision of dental care were highlighted. The treatment outcome showed a positive psychological impact on the well-being of the patient based on parental observations.
Anodontia

Oligodontia is a condition in which the patient has more than six ageneses, excluding the third molars. Whereas the absence of one tooth is quite common, oligodontia is a rare congenital condition that can happen with or without the syndrome. The condition happens due to disturbances during odontogenesis process. Management of oligodontia is a long-term process, and it involves prosthetic, restorative, and orthodontic treatment to support the oral function and esthetic of the patient. This article aims to report a rare case of agenesis of 13 permanent teeth (excluding third molars) in an 11-year-old girl and her treatment plan.

ABSTRACT Globally, non-syndromic tooth agenesis is commonly seen in clinical practice. However, its management is often complex and requires a multidisciplinary team approach for the maximal outcome. While various treatment options are possible, considerations for the treatment are not only based on the dentofacial conditions but also cultural and social background and personal preference of the patient. Thus, patientcentred care approach should always be practised for an optimal outcome. In the present case, a patient with established craniofacial growth presenting with bilateral agenesis of maxillary lateral incisors and over-retained deciduous maxillary left canine sought for aesthetic improvements. The patient did not prefer any orthodontic treatment citing a prolonged treatment duration and sub-optimal motivation as a hindrance. Thus, a prosthodontic only approach was taken by providing a conventional cantilever bridge and ceramic veneers to achieve the aims of treatment. This article discusses the possible limitation of such prosthodontic only solution in managing tooth agenesis.

Tooth agenesis, belonging to the abnormal tooth development, is a common disease in clinic. The disease not only affects the person's chewing function, but also influences the pronunciation, appearance and mental health. In the past, genetic linkage and molecular biology research have made clear of part of the genetic mutations' sites of the syndromic and non-syndromic tooth agenesis. Although the mechanism was not clear yet, but the important mutations are now known to be involved in many factors. Thesyndromic and non-syndromic tooth agenesis related gene are reviewed in this paper.

OBJECTIVETo compare and analyse the distribution and characteristic of born missing teeth.

METHODSA total of 183 simple hypodontia patients was reviewed and statistically analysed.

RESULTSThere was no significant difference in the number of missing teeth between different sexs (P > 0.05), and there was also no significant difference in the number of missing teeth among different sites (maxilla, mandible or left and right sides) (P > 0.05). The mandibular second premolar was the most frequently missing tooth. The missing molars were more commonly seen in oligodontia patients who had six missing teeth or beyond than hypodontia patients with less than six missing teeth (P < 0.05).

CONCLUSIONSEach hypodontia patient has his own clinical manifestation, and appropriate treatment should be planed accordingly for these patients.

A 19-year-old female patient came with the chief complaint that the upper anterior teeth looked small and with many spaces. The patient claimed that the tooth had never been replaced since birth. The patient wanted to improve the aesthetics of the tooth. Treatment, in this case, was made using a fixed prosthetic to aesthetically rehabilitate through prosthodontic treatment in the anterior teeth agenesis followed by attrition. It can be concluded that fixed prosthodontic treatment using a splint bridge is one treatment option that can be used in multiple anterior teeth agenesis followed by tooth wear. An appropriate material selection increases the aesthetics and functional aspects of the final treatment.

Orthodontic closure of old, edentulous spaces in the mandibular posterior region is a major challenge. In this report, we describe a method of orthodontic closure of edentulous spaces in the mandibular posterior region accelerated by piezoelectric decortication and alveolar ridge expansion. Combined piezosurgical and orthodontic treatments were used to close 14- and 15-mm-wide spaces in the mandibular left and right posterior areas, respectively, of a female patient, aged 18 years and 9 months, diagnosed with skeletal Class III malocclusion, hypodontia, and polydiastemas. After the piezoelectric decortication, segmental and full-arch mechanics were applied in the orthodontic phase. Despite some extent of root resorption and anchorage loss, the edentulous spaces were closed, and adequate function and esthetics were regained without further restorative treatment. Alveolar ridge expansion-assisted orthodontic space closure seems to be an effective and relatively less-invasive treatment alternative for edentulous spaces in the mandibular posterior region.

Hereditary hypohidrotic ectodermal dysplasia is a genodermatosis that demonstrates in its typical form a triad of hypohidrosis, hypotrichosis, and hypodontia Despite marked abnormalities of ectodermal structures, reports of cataract and corneal opacity have been conspicuously rare. This paper is a report of a case which shows the typical findings of HHED, congenital cataract, and corneal opacity.
