In isolation, this is not a very specific finding.  It is also
important in interpreting EEG results to be very precise about the
words that you choose e.g. "periodic" has a much different meaning to
an EEGer than does "episodic."  On the whole, temporal slowing is a
difficult finding to be certain about abnormality.  Temporal slowing
becomes more prominent as we age and has been theorized to be
secondary to microvascular changes in the brain.  It may also occur
with simple drowsiness.
If you were not drowsy *and* if the unilaterality was pronounced,
then it *might* suggest a focal area of cortical dysjunction in the
right temporal region.  The EEG cannot be more specific as to
etiology and a neuroimaging procedure might be considered if felt
clinically indicated.
