The victory in one hour, 16 minutes was the second of Tursunov's career after lifting an autumn 2006 title in India. He was beaten in the 2006 Los Angeles final by Tommy Haas.
Dancevic, ranked 109 but moving into the top 100 after the best run of his brief career, came in on a high after beating Andy Roddick in the semi-finals.
But the big-match experience of number 27 Tursunov played a key role in the final, played in brilliant sunshine.
Dancevic never had a breakpoint chance but managed 11 aces. He was the first Canadian to play an ATP final since Greg Rusedski won in Seoul in April 1995.
Tursunov was pleased to go through, joking: "At least this shows that wasn't a fluke."
The California-based Muscovite never faced a break point.
"I wasn't playing so well this week, but I've managed to lift my level with each match," Tursunov said. "The best thing to come out of this week is knowing that I can win when I'm not playing well. That will boost the confidence in future matches and for the rest of my career."
Dancevic blamed his tentative serve for his letdown, as he was broken in the penultimate game with Tursunov serving it out a game later.
"I didn't return as well as I would have liked," said Dancevic. "I was nervous in my first final. He was more confident out there. I made my own errors, and they came on my serve."
The Canadian said that he will take away a huge boost to his tennis. In the first round, he scored his first-ever victory over a top-50 player, German eighth seed Benjamin Becker.
"And I came back from a set and a break down in the second round against Juan Del Potro," Dancevic said. "I gained a lot from this week."
