Nowadays there is a need to search novel bioactive compounds from natural sources because of the increased number of emerging diseases in the globe with their rapid development and spread of multidrug-resistant pathogens (Ananda et al., 2010; Mane et al., 2017). Mostly novel antioxidant and anticancer bioactive compounds have to search from the natural entity. Somehow due to incomplete knowledge and unknown uses, many medicinal plants are lagging behind in the list of worldwide pharmaceutical research (Suryanarayanan et al., 2002; Aditi et al., 2017). The Indian research institutes such as National Chemical Laboratory, Department of Science and Technology and Department of Biotechnology has given high priority to the search for novel bioactive compounds to treat HIV, Tuberculosis, Kidney Stone, Cancer, and other microbial diseases (

Fluoride releasing adhesives combined with antibacterial monomer can play a vital role in reducing white spot lesions by enhancing the cariostatic effect especially in noncompliant\medically compromised patients.

Anchorage conservation has always been a challenge in orthodontics especially in cases requiring group movement of teeth. The drawbacks of conventional anchorage conservation methods like headgears and intermaxillary elastics have been overcome with the advent of skeletal anchorage. Mini-implants which have been proved successful in several intraoral locations for anchorage, can also be successfully placed in the maxillary tuberosity region. However, this site is not commonly used due to the fact that the density of bone in this region is comparably low. But with proper case selection and application of sound biomechanical principles, successful treatment results can be achieved with mini-implants placed in this location.The case reports discussed in the article demonstrates the ability of mini-implants when placed in the maxillary tuberosity for en masse distalization of the entire maxillary dentition, its advantages and biomechanics.

Objective: To investigate the effects of different surface conditioning methods on shear bond strength (SBS) of metal brackets bonded to porcelain surfaces and the influence of silane coupling agent in altering the bond strength. Materials and methods:A total of 80 feldspathic porcelain specimens were used. They were divided into eight different groups based on different surface conditioning methods and combinations: Sandblasting (SAB), hydrofluoric acid (HFA), diamond bur (DB) and air abrasion (AA). Silane coupling agent was used in five groups. Metal brackets were bonded and subjected to SBS testing. The efficiencies between the five individual methods used were analyzed. ARI scoring was done after debonding. Results:The SBS range was between 3.19 and 14.38 (MPa) with a mean of 8.89 ± 3.25 (MPa). The difference between mean SBS between different groups was significant (p < 0.001). As compared to DB-based group (10.46 ± 0.69 MPa) the non-DB based group were lower (8.66 ± 3.40 MPa) but the difference was not significant (p > 0.001). When compared to AA group (9.03 ± 0.59 MPa) the non-AA group were lower (8.87 ± 3.46 MPa) but again the difference was not significant (p > 0.001). ARI score 0 was observed in 47 instances (58.8%), score 1 was observed in 25 instances (31.2%). Conclusion:The results indicated that surface conditioning alone without silanation produced significantly low SBS. Air abrasion followed by silanation produced favorable bond strength and might have the potential to replace alternative methods.
