When a vital tooth is restored with a metal inlay or crown, a complaint that thetooth has become sensitive to cold water is sometimes heard. The same complaint can be made even after the restoration by porcelain jacket crown (a bad conductor of heat). Usually this complaint fades out when the occlusal adjustment is made properly. So it is considered that such hypersensitivity is caused by a high crown or supracontact.
In this paper treatment procedures for two patients are described and the relationship between a hypersensitive tooth and overload is discussed.
The first patient is a 40-years-old woman treated with a fixed partial denture. After cementation of prosthesis, opposite intact tooth became hypersensitive and recovered by occlusal adjustment of the prosthesis.
The second patient is a 17-years-old man with partial anodontia. His chief complaint was the hypersensitivity of existing teeth. His symptom was disappeared after insertion of a removable partial denture.
