Amalgam has been used to restore teeth Federal, state and local environmental agencies regulate for levels of affected by decay for more than a hundred years. More recently, “total mercury” because it does not degrade and can change from other materials, such as composite resins, have provided dentists one form to another, allowing it to migrate through the environment, and patients with an option other than amalgam, and because though there is insufficient scientific evidence that dental amalgam in composite restorations can match tooth color, they have become more the environment is a significant source of methylmercury. popular than the silver colored dental amalgam.

THE GERALD D. STIBBS GOLD FOIL SEMINAR MANUAL (Updated 2017)
THE GERALD D. STIBBS GOLD FOIL SEMINAR MANUAL (Updated 2017) COPYING: Any and all are welcome to use the contents of this manual in their efforts to improve their own restorative service and competence. This does not give or imply the right to reproduce the material as being the product of any other individual or group. If copied please continue to give credit to those who produced the work. DR. GERALD D. STIBBS This course is dedicated to the memory of Dr. Gerald D. Stibbs, who in the course of his career influenced the development of so many dentists, and carried on the tradition of excellence that began with Dr. W. I. Ferrier. Some insight into Dr. Stibbs character can be gained from the preface to one of his manuals: “To achieve competence with gold foil, one must read and more importantly, practice repeatedly the steps involved. While it is possible to become adept on one’s own initiative it is more practical to become an operating member of a study club that meets regularly, under the close supervision and coaching of a competent instructor. Courses of various time lengths have been given in these procedures. In general it is best for the beginner to plan on a ten-day program, given in either a single course, or in two five –day courses. With less than a five-day exposure, there is a tendency for the inevitable problems to surface in two or three days, and there is not enough time to overcome the difficulties. For refresher courses, three to five days of exposure are advisable. -

Methods: Six- to nine-year-old children (n=96) with all permanent first molars in occlusion were examined and assigned to two groups: GIC sealant or resin-based sealant. The sealants were applied according to the manufacturers’ recommendations. The assessment of sealant retention was performed at two-month interval sessions (n=6), when each sample was scored according to the following criteria: complete retention, partial retention or complete loss. The visual and tactile examinations were carried out with a WHO probe, mouth mirror, air syringe and artificial light. The data were submitted to descriptive statistics and survival analysis. Results: A total of 384 occlusal surfaces were analyzed. Independent of the tooth and evaluation time, slightly better results were achieved by the resin-based sealant, but the difference was not statistically significant. -

School-Based Dental Sealant Programs, This Issue Brief Now Turns to the Application of This Policy Lens to One State, Minnesota
ORAL HEALTH Issue Brief Policy Frameworks Supporting School-Based Dental Sealant Programs and Their Application in Minnesota Despite strong evidence of the effectiveness of school-based dental sealant programs, most states are not taking full advantage of this significant opportunity to improve children’s health.1 The Minnesota Department of Health Oral Health Program, with financial support from the Health Resources and Services Administration (HRSA), sought an analysis of laws and policies in Minnesota and throughout the United States that either facilitate or impede school-based dental sealant programs. This Issue Brief identifies innovative laws and policies for more widespread consideration, adoption and implementation at the state level. It suggests that a statewide, coordinated school-based dental sealant program may provide a policy framework for evidence-based, effective, and sustainable school-based dental sealant programs. Finally, it examines the current state of the law in one state, Minnesota. Background Dental care is one of our nation’s greatest unmet children’s health needs, and tooth decay is the most common chronic disease affecting U.S. children.2 Despite being almost entirely preventable,3 tooth decay is on the rise among young children and has been described as “a public health crisis.”4 Without adequate preventive care and treatment, tooth decay can cause pain and infection and can lead to difficulties with eating, speaking, learning, and socializing, among other issues.5 Children with oral health problems are more likely to miss school and to perform poorly in school.6 National estimates suggest that oral disease causes children to miss approximately 51 million school hours a year,7 making it the number one reason for missed school.8 There are significant disparities in children’s access to dental care, and low-income, minority, and rural children are particularly vulnerable. -
General& Restorative Dentistry
General& Restorative Dentistry Fillings 1. Amalgam restorations ( for small, medium large restorations) 2. Direct composite restorations (for small – medium restorations) 3. Glass ionomer restorations (for small restorations) 4. CEREC all ceramic restorations ( for medium – large restorations) Amalgam restorations: Every dental material used to rebuild teeth has advantages and disadvantages. Dental amalgam or silver fillings have been around for over 150 years. Amalgam is composed of silver, tin, copper, mercury and zinc. Amalgam fillings are relatively inexpensive, durable and time-tested. Amalgam fillings are considered un-aesthetic because they blacken over time and can give teeth a grey appearance, and they do not strengthen the tooth. Some people worry about the potential for mercury in dental amalgam to leak out and cause a wide variety of ailments. At this stage such allegations are unsubstantiated in the wider community and the NHMRC still considers amalgam restorations as a safe material to use in the adult patient. Composite restorations: Composite fillings are composed of a tooth-coloured plastic mixture filled with glass (silicon dioxide). Introduced in the 1960s, dental composites were confined to the front teeth because they were not strong enough to withstand the pressure and wear generated by the back teeth. Since then, composites have been significantly improved and can be successfully placed in the back teeth as well. Composite fillings are the material of choice for repairing the front teeth. Aesthetics are the main advantage, since dentists can blend shades to create a colour nearly identical to that of the actual tooth. Composites bond to the tooth to support the remaining tooth structure, which helps to prevent breakage and insulate the tooth from excessive temperature changes. -
Once Resin Composites and Dental Sealants Release Bisphenol-A, How Might This Affect Our Clinical Management?

Since some monomers may remain unpolymerized in the application of dental resin, they dissolve in the saliva. (2) Methods: The literature search was carried out in Pubmed, Cochrane and Embase databases. Randomized controlled trials, cohort studies and case-control studies that evaluated BPA levels in human urine, saliva and/or blood were included. -

An experimental resin sealant was formulated with 60 wt.% of bisphenol A glycol dimethacrylate and 40 wt.% of triethylene glycol (a) Universidade Federal do Rio Grande do dimethacrylate with a photoinitiator/co-initiator system. PHMGH was Sul – UFRGS, School of Dentistry, Dental Materials Laboratory, Porto Alegre, RS, added at 0.5 (G0.5%), 1 (G1%), and 2 (G2%) wt.% and one group remained Brazil. without PHMGH, used as control (GCTRL). The resin sealants were analyzed for degree of conversion (DC), Knoop hardness (KHN), and softening in solvent (ΔKHN), ultimate tensile strength (UTS), contact angle (θ) with water or α-bromonaphthalene, surface free energy (SFE), and antibacterial activity against Streptococcus mutans for biofilm formation and planktonic bacteria. There was no significant difference for DC (p > 0.05). The initial Knoop hardness ranged from 17.30 (±0.50) to 19.50 (± 0.45), with lower value for GCTRL (p < 0.05). All groups presented lower KHN after immersion in solvent (p < 0.05). The ΔKHN ranged from 47.22 (± 4.30) to 57.22 (± 5.42)%, without significant difference (p > 0.05). The UTS ranged from 54.72 (± 11.05) MPa to 60.46 (± 6.50) MPa, with lower value for G2% (p < 0.05). -
DENTAL MATERIALS FACT SHEET June 2001
DENTAL MATERIALS FACT SHEET June 2001 Received from the Dental Board of California As required by Chapter 934, Statutes of 1992, the Dental Board of California has prepared this fact sheet to summarize information on the most frequently used restorative dental materials. Information on this fact sheet is intended to encourage discussion between the patient and dentist regarding the selection of dental materials best suited for the patient’s dental needs. It is not intended to be a complete guide to dental materials science. The most frequently used materials in restorative dentistry are amalgam, composite resin, glass ionomer cement, resin-ionomer cement, porcelain (ceramic), porcelain (fused-to-metal), gold alloys (noble) and nickel or cobalt-chrome (base metal) alloys. Each material has its own advantages and disadvantages, benefits and risks. These and other relevant factors are compared in the attached matrix titled “Comparisons of Restorative Dental Materials.” A “Glossary of Terms” is also attached to assist the reader in understanding the terms used. The statements made are supported by relevant, credible dental research published mainly between 1993 - 2001. In some cases, where contemporary research is sparse, we have indicated our best perceptions based upon information that predates 1993. The reader should be aware that the outcome of dental treatment or durability of a restoration is not solely a function of the material from which the restoration was made. The durability of any restoration is influenced by the dentist’s technique when placing the restoration, the ancillary materials used in the procedure, and the patient’s cooperation during the procedure. Following restoration of the teeth, the longevity of the restoration will be strongly influenced by the patient’s compliance with dental hygiene and home care, their diet and chewing habits. -
