RESUMEN
Dental treatment for patients with physical or mental disability is often performed under general anesthesia due to level of cooperation with treatment, type and location of treatment, time required, or number of times patient is required to attend hospital. University hospitals are receiving an increasing number of requests from local private dentists and dental clinics to provide dental care for patients with physical or mental disability which can only be performed under general anesthesia. We carried out a retrospective survey of the routes of referral and types of dental treatment carried out in such patients under general anesthesia at Tokyo Dental College Suidobashi Hospital. The survey covered a 5-year, 9-month period from April 2006 to December 2011, during which 163 patients, comprising 106 men and 57 women, were treated. Their age ranged widely, from 2 to 53 years, with a high proportion (118 patients, 72.4%) being minors aged under 20. Among the total number of patients, 69 (42.3%) had disorders associated with mental retardation. One hundred and two patients (62.6%) had been referred from other medical institutions, with a particularly high number coming from public dental clinics for patients specializing in such patients. Conservative restorative procedures were performed in most cases (59.4%), with composite resin restorations being particularly frequent. After treatment, many patients returned to their referring medical institutions, which were responsible for subsequent management, but information on the posttreatment status was not available for some patients. Tokyo Dental College Suidobashi Hospital frequently collaborates with local medical institutions, and the present results suggest the importance of improving such collaboration.

In this study we focused on dental anomalies peculiar to children and investigated how 3D-surgical planning and simulation could be applied to each case. This study included 3 patients (2 female and 1 male, 8 to 12 years). The CT imaging was performed via a SOMATOM Plus4. From the resulting data, an image of the tooth and bone was rendered using image analysis software Amira 3.1 which was then used to reconstruct three-dimensional images. The reconstructed 3D images were imported to 3D modeling software, which provided the basis for the surgical simulations. From these results, we were able to gain important insights that helped shape the planning of the surgical operation. Furthermore we consider that these findings would be useful for the patient when taking them through the process of obtaining informed consent.

Abnormalities in number of teeth are occasionally noted in clinical cases. Many theories have been proposed as regards the causes of the occurrence of supernumerary teeth, including atavism theory, mechanical tooth germ separation theory, tissue induction theory, and dental laminar morphological disturbance theory. However, none of these theories alone offers a sufficient explanation for this phenomenon. The incidence of supernumerary permanent teeth is approximately 1-3%. These are the maxillary anterior teeth, the maxillary molars, and the maxillo-mandibular premolars in terms of descending order of site of occurrence. On the other hand, incidence in the mandibular anterior tooth area, of which there have been few detailed reports, is about 0.01%, a markedly low value. In this paper, we report two rare cases of supernumerary teeth in the mandibular incisor area. We discuss their etiology and orthodontic treatment, and detail a differential diagnosis between the normal and supernumerary teeth. We found that it was difficult to establish a clear etiology and differentiation between the normal and supernumerary teeth.
