In this clinical study, 19 full metal crown restorations of canine teeth were placed in seven working dogs. Thirteen canine teeth were severely abraded with no involvement of the pulp cavities; six fractured canine teeth were endodontically treated. At least 1/3 of the coronal part of the canine tooth was available for a supragingivally performed, minimal tooth crown preparation. An adhesive te...

Many dental practitioners do not use adhesive bridges because of concerns over high failure rates. Techniques for these restorations should be based on the fundamental principles of bridge design which require rigid, accurately fitting frameworks and careful control of the occlusion. The abutments generally require little if any tooth preparation. Greater security will result from more extensiv...

T HE USE of conventional or increased handpiece operating speeds for the shaping of cavities in human teeth results in vibration, temperature changes, and other physical factors within the calcified tooth tissue and its organic matrix. The airbrasive and ultrasonic methods of cutting tooth tissue appear to create similar forces. The effects of these trauma may or may not be significant to the l...

Background Intraradicular procedures remove radicular dentin and jeopardizing longevity of a tooth. Traditional in vitro methods used to determine the remaining dentin thickness (RDT) have limitations. Aim The aim is to evaluate, using cone-beam computed tomography (CBCT), RDT following rotary instrumentation and post space preparation in buccal and palatal roots of maxillary first premolars....

BACKGROUND AND OBJECTIVE Dentists often question the use of resin-bonded fixed partial dentures (RBFPDs) for reliable restoration of tooth-bound edentulous spaces. Initial attempts at bonding fixed partial dentures on teeth resulted in early failure due to debonding. In the 1980s and 1990s, improvements in preparation methods, metal alloys and bonding techniques made the RBFPD a more predictabl...

OBJECTIVE This study evaluated the correlation between laser fluorescence readings and the extent of incipient occlusal caries as measured by the volume of tooth preparation in vitro. MATERIALS AND METHODS One hundred and three permanent molars and premolars containing incipient occlusal pit-and-fissure caries and sound occlusal surfaces (1/4 of the sample, control) were selected. DIAGNOdent ...

UNLABELLED Resin-bonded, fixed partial dentures have the potential to offer a minimally invasive, fixed-prosthetic approach to tooth replacement in patients who may not be candidates for implant therapy. However, traditional preparation protocols often recommend extensive preparation designs on two abutment teeth, thereby potentially compromising the long-term health of the adjacent abutments a...

results most dental students had cavity preparation, handwriting and drawing skills above the average. a significant correlation was found between drawing and tooth preparation skills (p < 0.05). background acquiring fine psychomotor skills is challenging for dental students. objectives this study aimed to assess the correlation of cavity preparation skills with drawing skills and handwriting o...
