Williams syndrome is a rare congenital disorder with various physical abnormalities and characterized by facial, oral, and dental features. Individuals with Williams syndrome typically have eating disorders in the early childhood, which lead to prolonged night feeding. Prolonged night feeding is a risk factor for rampant dental caries. Williams syndrome is caused by the microdeletion of chromosome 7, resulting in elastin deficiency. Elastin is integral to cardiovascular health. Many patients with Williams syndrome have complex cardiovascular abnormalities that must be considered a part of dental management. Complications related to cardiovascular diseases may induce adverse effects such as dangerously elevated blood pressure. This may occur in patients during stressful dental treatment. In addition, characteristics of auditory hyperalgesia and anxiety disorders among patients with William syndrome, complicate receiving routine dental management. Therefore, dental treatment under sedation or general anesthesia may be preferable for patients with Williams syndrome; in particular, patients who are very uncooperative and/or needs extensive dental treatment. A thorough evaluation of each patient's physical condition is required before making decisions regarding dental treatment. Careful monitoring and preparation for emergencies are very important during and shortly after dental treatment under general anesthesia or sedation. Monitoring is critical until vital signs have stabilized and return to normal. A 28-month-old man diagnosed as having Williams syndrome, visited the Dental Hospital of ${\bigcirc}{\bigcirc}$ University for the management of rampant dental caries. We reported on the management of this patient who had peripheral pulmonic stenosis, and received dental treatment under general anesthesia. We also reviewed the characteristics of Williams syndrome and discussed considerations for dental treatment under general anesthesia.

Dental composite resin is a kind of the particle - reinforced composite material, and is widely used in recent dental restoration of anterior and posterior tooth region. The purpose of this study was to investigate the fracture behaviour according to volume fractions and external findings of the filler particles for better interpretation of the fracture characteristics of posterior dental composite resins by analytic method of fracture mechanics. The plane strain fracture toughness($K_{IC}$) and Acoustic Emission were determined with three - point bending test using the single edge notch specimen according to the ASTM - E399, and its analyzed data was compared with filler volume fractions derived from the standard ashing test and scanning electron fractographs of each specimen including the unfilled experimental resin as a control. The results were that the value of fracture toughness of the composite resin material was in the range from 0.85 MPa$\sqrt{m}$ to 1.60 MPa$\sqrt{m}$ and was higher than the value of the unfilled experimental resin, and the fracture behaviours dervied from Acoustic Emission analysis show prominent differences according to the volume fraction and the size of filler particles used in each composite resin. The degree of resistance against crack propagation seems to be increase and the fractographs demonstrate the high degree of surface roughness and irregularity according with the increase of fracture toughness value.
