Dental treatment for patients with physical or mental disability under general anesthesia at Tokyo Dental College Suidobashi Hospital.

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.

CT image applications for pre-surgical assessment and surgical pre-planning in Pediatric Dentistry.

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.

Two cases with supernumerary teeth in lower incisor region.

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.
