Founded in 1988 as the first private institution of higher education in the United Arab Emirates and the Gulf region, Ajman University (AU) is now being recognized as an emerging leader on the global academic map.

The 2020 QS World University Rankings lists AU in the top 800 universities globally and among the top 10 worldwide for international students and faculty! The &ldquo;Top 50 Under 50&rdquo; QS Rankings names AU as one of the top 150 young universities in the world. Even our distinct location in the Dubai/Sharjah/Ajman corridor is ranked by QS as the 61st best student destination on the planet. Recently, Ajman University earned Five QS Stars in three ratings categories -- Social Responsibility, Inclusiveness and Learning Environment. We also garnered Four QS Stars for both Teaching and Internationalization.

This research is to investigate the effect of 810 nm diode laser irradiation root dentine mineral contents and smear layer removal when used along with 2.5% (NaOCl) and 17% (EDTA) irrigation. Eighteen (18) freshly extracted permanent premolar teeth were collected; the sample was chemo- mechanically prepared using ProTaper rotary nickel-titanium ((Ni-Ti) instruments and 2.5% (NaOCl). The Sample was divided into, Group A: (8) teeth treated with 5 ml of 17% EDTA only for 1 minute, Group B: (8) teeth were treated with 5 ml of 17% EDTA A for 1 minute then irradiation with 2 W power continuous wave of 810 nm diode laser. A control group of (2) teeth were irrigated only with 5 ml saline. Teeth were then sectioned, (1000x and 2000x) photomicrographs of the root canal walls were taken at 2 mm, 7 mm, and 12 mm depth from the apex the examined under SEM. Regarding smear layer removal no statistically significant difference was detected between the two groups (P &gt; 0.05) in term of cracks and conjugation less changes were observed in teeth treated with EDTA a lone compared with Diode +EDTA group (12.5% &amp; 21% respectively). 810 nm diode laser irradiation of root canal dentin irrigation has no significant effect on removal of smear layer. It can cause more dentine erosion with slightly more additional loss of mineral content when used along with NaOCl and EDTA. © 2019 Journal of International Dental and Medical Research.
