The expression "Smart restorative material" alludes to those that can be changed in controlled style for example, stress, temperature moisture, pH and electrical or attractive fields. The need of great importance is to present dental materials that have biomimicking properties of regular tooth structure. Different biocompatible materials have been presented and generally utilized in numerous fields of dentistry. Smart restorative behaviour of substances occurs while it detects a few improvements from the overall circumstance and responds to it in a helpful, reproducible and for the maximum element reversible way. A key component of smart conduct incorporates its capacity to come back to the first state. A portion of these materials utilized are altered glass ionomers, calcium phosphate discharging pit and fissure sealants, smart composites, smart ceramic, compomers, orthodontic shape-memory alloys, amalgams, smart impression materials, smart sutures, smart burs, smart endodontic files and so forth. These materials have changed the dentistry and are the start of another part in Biosmart Dentistry.

The aim of this study was to evaluate in vitro the marginal microleakage of different materials used as pit-and-fissure sealants (Delton, Filtek Flow, Dyract Flow and Vitremer). Fifty-six extracted sound human third molars were randomly assigned to 4 groups (n=14). After sealant placement, the teeth were thermocycled (500 cycles; 5ºC, 37ºC and 55ºC), isolated, immersed in 2% buffered methylene blue dye for 4 h, included in acrylic resin and sectioned longitudinally in a buccolingual direction. The sections were analyzed for leakage using an stereomicroscope. A 4-criteria ranked scale was used to score dye penetration. All materials exhibited dye penetration to some extension and no statistically significant difference was observed among the groups (p>0.05). In conclusion, the findings of this study showed that a flowable composite resin, a flowable compomer and resin-modified glass ionomer placed on occlusal pits and fissures had similar marginal sealing as the unfilled self-cured resin-based sealant.

Objective: The aim of this study was to evaluate the retention of glass ionomer sealant, Vitro Molar(r) (DFL) and Ketac Molar Easy Mix(r) (3 m ESPE) as pit and fissure sealants on first permanent molars, fully or partially erupted. Methods: The study sample consisted of 412 molars, among 110 children. The sealant retention was evaluated after 6 months of the application. Results: The results were collected through digital photographs and the retention results were assessed by the following System: score 0 - total retention; score 1 - sealant present in more than 50% of the pit and fissure system; score 2 - sealant present in less than 50% of the pit and fissure system; score 3 - missing sealant. Regarding the presence of the sealants in less than 50% of the occlusal surface, lower percentages were found for the two materials used as follows: score score 2 - Vitro Molar(r) (9,52% examiner 1 and 11.9% examiner 2) and score 2 - Ketac Molar Easy Mix(r)(9.52% examiner 1 and 10.71% examiner 2). Approximately 90% of the teeth sealed with Ketac Molar Easy Mix(r)or Vitro Molar(r) presented total loss (score 3). Thus, there was no statistical difference between the materials and between the examiners (p>0.05). Conclusion: Therefore it was concluded that the sealant retention in the studied population was not satisfactory for any of the materials used.
