Retention of Metal-Ceramic Crowns-Which Cement is better
J Am Dent Assoc, Vol 140, No 9, 1125-1136.
Powder-liquid versions of new cements were significantly more retentive than were paste-paste versions of the same cements. The mean value of crown removal stress for the new self-adhesive modified-resin cements varied appreciably among the four cements tested. All cements retained castings as well as or better than did zinc phosphate cement.
Clinical Implications. Powder-liquid versions of cements, although less convenient to mix, may be a better clinical choice when crown retention is an issue. All cements tested will retain castings adequately on ideal preparations because the corresponding removal stresses are comparable with or higher than those associated with zinc phosphate. Powder-liquid resin-modified glass ionomer cement, selected self-adhesive modified-resin cements and conventional resin cements provide additional retention when desired.
However, the victims have alleged they were ragged by their batchmates."There has been no official complaint by any of the students, yet after the issue was brought to our notice, the management is investigating into the matter. At present, college romance' seems to be the possible cause behind the clash," Dr Durgesh N. Bailoor, principal, Jaipur Dental College, said.
"Since both the victims' and the accused are third year students, the chances of ragging are bleak," Durgesh N. Bailoor added. More
Dental Clinic Receptionist Jailed for stealing
SAN DIEGO - A Paradise Hills woman pleaded guilty Tuesday to four felony charges for stealing about $72,000 from the bank accounts of patients of several area dental offices where she worked as office manager.

Woman awarded £1.4million for BAD dentistry
24th Aug 2009
A jury in South Carolina has awarded damages in the amount of £1.4 million ($2million) to a woman who had 13 of her teeth mistakenly extracted by a dentist.
Back in 2006, Elizabeth Smith, aged 28, attended the Sexton Dental Clinic for dental treatment involving the extraction of three teeth. For some reason, the dentist proceeded to remove all of Ms Smith's upper teeth, resulting in a total extraction of 16 teeth.
Ms Smith's lawyer, Robert Ranson, said his client is now looking forward to having remedial dental work performed, which, it is thought, will cost in the region of £50,000 ($80,000).
Mr Ranson had claimed that the clinic's employees tried to cover up the mistake by altering the paperwork.
The Sexton Dental Clinic denies any wrongdoing and is considering appealing the judgment.
The survey was conducted between July 16th and July 25th via email and among dentists in the Chicago Dental Society's Facebook Fan Page. More
Implant-supported fixed cantilever prosthesis in partially edentulous jaws: a cohort prospective study
Clinical Oral Implants Research
Published Online: 26 Aug 2009
The aim of the present study was to assess the clinical outcome of patients treated with implant-supported fixed partial dentures (FPD) with cantilever after a mean follow-up time of 8 years.
The study included 45 consecutive partially edentulous patients treated between January 1994 and August 2006 with 59 partial cantilever fixed prostheses supported by 116 ITI® implants. The primary outcome variable considered was the presence of complications at the subject and bridge level; the secondary outcome variable was marginal bone loss (MBL). The frequency of complications was analyzed according to cantilever location and opposite dentition and tested by Fisher's exact test. A multilevel regression model was constructed to analyze the factors influencing MBL with three levels: subject as the highest, and then implant and site. During the follow-up period, 11 implants showed a bone loss exceeding the limit for success, out of which two implants showed an infection of the peri-implant tissue.
Results: After an average observation of 8.2 years of cantilever prostheses loading, the implant success and survival rates were 90.5% and 100%, respectively. Besides, the prosthetic success and survival rate were 57.7% and 100%, respectively.
None of the predictors included in the multilevel model presented a significant impact on the bone loss between baseline and the follow-up examination.
Conclusions: The authors concluded that the prognosis of implant-supported FPDs and marginal bone loss at implants were not influenced by the position or the length of the cantilever, the location of the bridge and type of opposite dentition. Implant-supported fixed cantilever prosthesis can be considered a suitable treatment choice.
