I never liked this subject when I studied back in my graduation, but after I joined the course everything made sense. Dr Hafez is not just very smart, but he also knows how to communicate with his students in a easy way to learn. I passed my exam and I am very grateful for everything this course taught me.

Thank you for ur lecture sir. U were actually right in 8.07sec, tat primer is hydrophilic (it is both hydrophilic- towards dentin and hydrophobic- towards bonding agent). And we use primer expecially in dentin bcoz although the collagen in hydrophilic the surface energy is comparitively low compared to hydroxyapatite.
Dentin is hydrophillic not hydrophobic as u say at 8,13 seconds into video. . Primer molecules contain two functional groups-a hydrophilic and a hydrophobic group. The hydrophilic group has an affinity for the dentin surface, and the hydrophobic group has an affinity for the resin.

Primer has a hydrophilic portion and a hydrophobic portion, the hydrophilic adheres to collagen, and the hydrophilic faces outward to adhere to resin in the bonding agent. I tried to summarize, we have this all explained in detail in our course videos :)
