1/8. Spaced dentition--open, close or redistribute?

    A spaced dentition can be due to various reasons such as hypodontia, tooth size discrepancy and impeded eruption. The dilemma for clinicians is whether to close, open or redistribute space. Closing space by orthodontics eliminates the need for prosthetic rehabilitation but it might compromise aesthetics and function. On the other hand, opening space is more complex and requires long-term maintenance. Based on these drawbacks, a careful occlusal analysis and an individualized treatment plan are mandatory for achieving the best result. The prognosis for closing space and substituting congenitally missing maxillary laterals with canines depends on factors such as overjet, lip support, crown colour, shape and root position. If these are unfavourable, opening space for prosthetic replacement is then preferred. Discrepancy between tooth and jaw size results either in spacing or crowding. The location of the spacing and the amount of overjet are important factors guiding the direction of treatment.

2/8. Hypodontia: etiology, clinical features, and management.

    patients who are congenitally missing one tooth or more are frequently encountered in routine practice. The etiology, classification, and clinical features of hypodontia are reviewed, and treatment modalities are discussed. One case of mild-to-moderate hypodontia and one case of severe hypodontia are described. Osseointegrated implants have provided encouraging results, especially in patients who are missing anterior teeth or who have severe hypodontia.

3/8. Management of severe hypodontia.

    Developmental absence of one or more teeth referred to as hypodontia is frequently encountered in dental practice, whereas severe hypodontia is a rare developmental dental anomaly. A case of severe hypodontia is presented. It was successfully treated with osseointegrated implants.

4/8. Hypohydrotic ectodermal dysplasia: an unusual presentation and management in an 11-year-old Xhosa boy.

    ectodermal dysplasia (ED) is an inherited disorder in which two or more ectodermally derived structures fail to develop, or are abnormal in development. Hypohydrotic ectodermal dysplasia (HED) or Christ-Siemens-Touraine syndrome, is an X-linked recessive syndrome with an incidence of 1/10,000 to 1/100,000 births. Because of its X-linked inheritance pattern, it is more common in males. HED is characterised by hypohydrosis (diminished perspiration), hypotrichosis (decreased amount of hair) and microdontia (small teeth), hypodontia (lack of development of one or more teeth) or adontia (total lack of tooth development). These patients present diagnostic and treatment challenges because of variable oral manifestations. This report describes an 11-year-old Xhosa boy, who was referred to the University Dental faculty by his general medical practitioner because of hypodontia. General facial features included: frontal bossing, a depressed nasal bridge, 'butterfly' pattern of eczema over the nasal bridge to the malar process of each cheek, thinned out hair, loss of vertical dimension of face and dry skin. Intra-oral examination revealed hypodontia with peg-shaped anterior teeth and diastemas. Radiological examination revealed no developing permanent teeth or tooth buds. diagnosis was confirmed by doing a sweat gland count. Management included oral hygiene instruction, fluoride treatments, construction of a partial lower denture and counselling about his condition with particular reference to the danger of hyperthermia and control of allergies.

5/8. Dubowitz syndrome: report of a case with emphasis on the oral features.

    Dubowitz syndrome is a rare condition in which the affected individual presents with dysmorphic facial features and manifests growth retardation. Although the condition is well reported in the medical literature, the dental manifestations have not been discussed in great detail. Some of the dental features reported include macrodontia, hypodontia, delayed eruption, and midline diastema. The purpose of this case report was to describe a young Chinese patient with Dubowitz syndrome with specific oral features.

6/8. Multidisplinary management of hypodontia in adolescents: case report.

    The purpose of this article is to describe a team approach to treatment of hypodontia in adolescent dentition. A case report of hypodontia with a microdontic lateral incisor in a Class I malocclusion illustrates the principles of case management. Multidisciplinary consultation during treatment planning and coordination and appropriate timing of subsequent interdisciplinary dental care enables the clinician to provide the optimum care. The scope of orthodontic and restorative management depends on the severity of the hypodontia.

7/8. Hypodontia of the permanent dentition. case reports.

    Hypodontia has been observed as one of the most common human dental developmental anomalies. It may be defined as agenesis of one or more teeth. The prevalence in the permanent lower central and lateral incisor region is low, ranging from 0.23 percent to 0.08 percent, respectively. This is compared with an overall incidence of hypodontia of 3.49 percent. However, significant racial variation occurs. Treatment options generally available are: no treatment, closure of spaces orthodontically, or prosthetic replacement. Aetiology, associated anomalies, and factors involved in treatment choice are discussed. A report of four cases of hypodontia of the permanent lower anterior teeth and their orthodontic management is presented.

8/8. ectodermal dysplasia: a review and case report.

    ectodermal dysplasia is a hereditary disease characterized by a congenital dysplasia of one or more ectodermal structures and their accessory appendages. Common manifestations include defective hair follicles and eyebrows, frontal bossing with prominent supraorbital ridges, nasal bridge depression, and protuberant lips. Intraorally, common findings are anodontia or hypodontia, conical teeth, and, consequently, generalized spacing. The patient may suffer from dry skin, hyperthermia, and unexplained high fever as a result of the deficiency of sweat glands. The present review focuses on the clinical manifestations, classifications, and diagnosis of ectodermal dysplasia. A 6-year-old girl, described in the case report, exhibited many of the manifestations of ectodermal dysplasia as well as behavioral problems and a severe gag reflex. The treatment to improve her appearance and oral function included a removable prosthesis, acid-etch-retained indirect resin composite veneers, and a fixed partial denture.
