The past decade has been turbulent for dental education, marked by debate about the future directions of the curriculum and the profession itself. The bulk of the dental school curriculum is still devoted to tooth restoration or replacement techniques, although the need for these procedures has declined. Some dental educators now advocate an oral physician model as the desired direction for the...

Mercury is among the most toxic nonradioactive elements which may cause toxicity even at low doses. Some studies showed release of mercury from dental amalgam fillings in individuals who used mobile phone. This study was conducted to assess the effect of high-field MRI on mercury release from dental amalgam filling. We studied two groups of students with identical tooth decays requiring a simil...

Chromatin structure is modulated during deoxyribonucleic acid excision repair, but how this is achieved is unclear. Loss of the yeast Ino80 chromatin-remodeling complex (Ino80-C) moderately sensitizes cells to ultraviolet (UV) light. In this paper, we show that INO80 acts in the same genetic pathway as nucleotide excision repair (NER) and that the Ino80-C contributes to efficient UV photoproduc...

Rectocele is an herniation of the rectum through the rectovaginal fascia and posterior vaginal wall causing a protrusion into the vaginal lumen. It’s a common disorder in women with history of multiple vaginal deliveries and it is asymptomatic in 80% of cases. Symptomatic rectocele is less common, usually affects postmenopausal females, and results in obstructed defecation and constipation. Sur...

statement of the problem: porcelain laminate veneer is an esthetic restoration used as an alternative to full veneer crowns and requires minimal tooth preparation. in restoration with porcelain laminate veneers, both the longevity of the laminate and conservation of the sound tooth structure are imperative. purpose: the present study aimed to investigate the shear bond strength of porcelain lam...

The Journal of Dental Hygiene Vol. 89 • Suppl. 1 • February 2015 According to the CDC, between 12.1% and 41.9% of the American population ages 5 years and older (depending on age and income level) has untreated dental caries.

Cell-based tissue repair of the tooth and - tooth-supporting - periodontal ligament (PDL) is a new attractive approach that complements traditional restorative or surgical techniques for replacement of injured or pathologically damaged tissues. In such therapeutic approaches, stem cells and/or progenitor cells are manipulated in vitro and administered to patients as living and dynamic biologica...


 ABSTRACT: Dental fractures comprise the most frequent form of traumatic dental injury and often require an immediate procedure for their treatment. Among treatments, restoration fractured teeth by reattachment tooth fragment to its remnant is a viable clinical treat fracture due trauma because it considered highly conservative technique.

Composite resin restoration has been increasingly used in restorative dentistry with patient’s demands, and also composite resin materials as well as bonding agents have been developed continuously. Despite of these developments, several factors, such as inadequate form, wear, color mismatch, chipping or bulk fracture may still present concerns. In case of failure, the clinician must determine ...
