“…Based on the method of polymerization resin-based sealants are classified as auto-polymerized and light polymerized [ 10 ]. The auto-polymerized sealants, also known as self-cure, are two-component systems [ 11 ]. These auto-polymerized sealants have more or less been replaced by light-polymerized sealants [ 11 ].…”

The occlusal surface of a tooth is affected by the development of biofilm in pits and fissures as bacteria and food particles accumulate in its complex structure. In this study, miswak fibers containing cellulose and antimicrobial extract were incorporated in commercial pit and fissure sealants. The miswak powder was characterized by different analytical techniques. The powder was mixed in different ratios (0–5%) into a pit and fissure sealant to result in five sealants (Groups 0–5), and their mechanical properties i.e. flexural strength, compressive strength, and Vickers hardness were evaluated. The sealants were also evaluated against streptococcus mutans oral pathogenic bacteria. SEM analysis confirmed irregular shape and micron-size particles of miswak powder. The infrared spectral analysis and X-ray differential peaks showed characteristic peaks related to miswak fibers. The particle appearance increased in prepared pits and fissure sealants with higher loading of miswak powder in SEM analysis. The flexural strength, compressive strength, and Vickers hardness values were obtained in the range of 148–221 (±16.6: p -value < 0.001) MPa, 43.1–50.3 MPa (±1.7: p- value <0.001), and 15.2–21.26 VHN (±0.56: p -value <0.001) for control and prepared sealant specimens respectively. In the antibacterial study, the zone of inhibitions increased with increased content of miswak from 15.6 ± 0.45 mm (Group 1) to 20.3 ± 0.32 mm (Group 5). The MIC was calculated to be 0.039%. The prepared experimental sealant had acceptable mechanical and good antibacterial properties therefore it could be recommended as an efficient pit and fissure sealant.

“…2 Recently, nanotechnology has been introduced in the dentistry which contains small particles of 0.1-100 nanometers ranges. 4 These small particles are favorable to obtain good wear resistance, easy polishable and better esthetics. 5 Firstly, developed nanofillers composite resin obtains high fracture toughness, better lasting polish, retention and aesthetics, and higher wear resistance.…”

The aim of this study was to compare the clinical performance of nanohybrid composite resin in Class II restorations placed with a one-step self-etch adhesive with that of microfilled composite resin of permanent posterior molar teeth. A total of 100 participants who received Class II restorations either with nanohybrid composite resin bonded with a single step self-etch adhesive or conventional microfilled composite bonded with a single step self-etch adhesive. All restorations were evaluated by using slightly modified USPHS criteria at baseline and after 3, 6 and 12 months. The results revealed that nanohybrid composite resin showed better clinical outcome than that of the conventional microfilled composite resin restorations in respect to retention and marginal adaptation at 12 months observation period. It can be concluded that nanohybrid is superior to conventional microfilled composite resin in respect to retention, and marginal adaptation of Class II restorations of permanent molar teeth.

“…15 Furthermore, abrasion resistance and fluoride release have been increased. 16 In addition, they have minimum voids, cracks and microporosities on the surfaces of nanofilled resin-modified glass ionomer than the conventional ionomers. 17 Therefore, nanofilled resin-modified glass ionomer (Ketac Nano 100 TM ) is considered as a reliable alternative to other conventional glass ionomer (Fuji IX) as a pit and fissure sealant.…”

The present study compared the clinical performance of nanoparticulated resin modified glass ionomer and conventional glass ionomer pit and fissure sealant on permanent molars. Fifty patient having bilateral occlusal grooves in pits and fissures of the occlusal surface were included for this study where 50 teeth were treated with nanopaticulated resin modified and the remaining 50 teeth were subjected to conventional glass ionomer sealants. The color match, retention and marginal adaptation were assessed at 3, 6 and 12 months and statistical analysis was performed by Chi-square test to assess the difference between the two sealants; a values of <0.05 was considered as statistically significant. The results showed that although there were no significant differences between two sealants at baseline and 3 months observation period but nanoparticulated resin modified glass ionomer sealants showed better clinical performance than that of conventional glass ionomer sealants at 12 months and the differences between two sealants were statistically significant (p<0.05). It can be concluded that naqnoparticulated resin modified glass ionomer sealant exhibited better color stability, more retention, and better marginal adaptation than those of conventional glass ionomer sealants at 12 months observation period.
