What categorizes a class 1 recession according to Miller?

Recession not extending to mucogingival junction
Recession extending to MCJ or beyond with no bone loss
Recession extending to MCJ with bone loss preventing total root coverage
Recession extending to MCJ with severe bone loss

The correct answer is: Recession not extending to mucogingival junction

A class 1 recession, as categorized by Miller, refers to a recession that does not extend to the mucogingival junction (MCJ). This means there is still healthy tissue present at the MCJ, preventing the recession from reaching this point. Option B is incorrect because it describes a recession that extends to the MCJ, which would technically be considered a class 1 recession according to some other classification systems. Option C is incorrect because it adds the detail of bone loss, but does not specify the extent of the recession. It is likely describing a class 2 recession (where the recession extends beyond the MCJ). Option D is incorrect because it describes a class 3 recession, where the recession extends to the MCJ and there is severe bone loss present.
