Fiber inserts incorporated at the gingival floor of Class II composite restorations resulted in a significant reduction of microleakage scores as compared to restorations made without inserts. This may lead to a reduced incidence of recurrent caries. SUMMARYPurpose: This investigation evaluated the effect of glass and polyethylene fiber inserts on the microleakage of Class II composite restorations with gingival margins on root surfaces. Methods: Fifty-four intact molars were sterilized with Gamma irradiation and mounted in acrylic bases. Class II slot cavities were made on both proximal sides of each tooth (3 mm wide, 1.5 mm deep) with the gingival margin on the root surface. The teeth were divided into nine groups, according to the technique of restoration and type of bonding agent. Filtek P-60 (3M/ESPE) was used to restore all cavities. Two types of fiber inserts were used: glass fiber (Ever Stick, StickTech) and polyethylene (Ribbond-THM), with three bonding agents being employed: Scotch Bond Multipurpose (3M/ESPE), Clearfil SE Bond (Kuraray) and Xeno IV (Dentsply). In the experimental groups, 3 mm long fiber inserts were inserted into restorations at the gingival seat. The control groups had no fiber inserts. The restorations were made incrementally and cured with LED light (UltraLume5, Ultradent). The restored teeth were stored in water for two weeks, then thermocycled for 3,000 cycles (5°C and 55°C). The tooth surfaces were sealed with nail polish, except at the restoration margins. The teeth were immersed in 2% procion red dye solution, sectioned and dye penetration was assessed to determine the extent of microleakage

“…Over 50% of respondents chose calcium hydroxide with or without a secondary base despite the lack of evidence regarding its effectiveness. 15 A further example of the continued use of outmoded techniques was provided by the answers to Question 6 which asked about the development of auxiliary retention in a large posterior cavity. A cavity of these dimensions was selected as it would have been less appropriate to restore it with directly placed composite resin 16 and therefore it was a reasonable question to ask specifically about the retention for silver amalgam.…”

“…[23][24] Microleakage of the coronal restoration then allows bacteria to migrate pulpally and initiate degenerative pathosis. [25][26] MTA has proven to be one of a very few exogenous materials that is not only well tolerated by connective tissues, 27 but also contributes to a bacteria-tight seal. 28 Both properties suggest that an application of MTA as a pulp capping material may be clinically successful under the conditions of minimal bacterial exposure.…”

©Operative Dentistry, 2010, 35-1, 20-28 JP Miles • AH Gluskin D Chambers • OA Peters Clinical RelevanceCarious pulp exposures present a therapeutic challenge for clinicians. Mineral trioxide aggregate (MTA) is a treatment option that may provide successful outcomes for the capping of carious pulp exposures in adult patients. However, the success measured as pulp survival over a period of one and two years of pulp caps performed by undergraduate dental students may be low. This study provides data regarding the impact of exposure sizes and other pre-operative variables on outcomes of MTA pulp caps in adults. SUMMARYThe current study estimated pulpal vitality after MTA pulp caps were performed by undergraduate student clinicians. At recall after 12 to 27 months, 51 pulp caps were clinically and radiographically assessed. Kaplan-Meier analyses were used to estimate overall success at 12 and 24 months, determined as the presence of a vital pulp, as well as impact of preoperative variables on pulp vitality at recall. Overall, one-year pulp survival was 67.7%, while the two-year survival rate was 56.2%. Tarone-Ware statistics indicated that neither age of the patient nor size of the exposure ("minimal" or "moderate") and the amount of bleeding ("none," "minimal" or "moderate") had a significant effect on survival rates.Within the limitations of the current study on procedures performed by student clinicians, it may be concluded that, for MTA pulp caps applied to carious exposures in adults, certain preoperative conditions-patient age, exposure size and amount of bleeding-are not predictive of clinical outcome. Considering the comparatively low success rate for the current cohort, more research is needed to define predictive criteria for successful pulp capping with MTA.
