MEMORANDUM **

Dwayne Eichler, a California state prisoner, appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging deliberate indifference to his serious medical needs. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir. 2004). We affirm.

The district court properly granted summary judgment because Eichler failed to raise a genuine issue of material fact as to whether defendants were deliberately indifferent to Eichler’s dental needs. See id. at 1058 (prison officials act with deliberate indifference only if they know of and disregard an excessive risk to inmate health); Jackson v. McIntosh, 90 F.3d 330, 332 (9th Cir. 1996) (to establish that a difference of opinion amounted to deliberate indifference, a prisoner must show that the defendants’ chosen course of treatment was medically unacceptable and in conscious disregard of an excessive risk to the prisoner’s health).

We do not consider matters not specifically and distinctly raised and argued in the opening brief. See Padgett v. Wright, 587 F.3d 983, 985 n. 2 (9th Cir. 2009) (per curiam).

AFFIRMED.
