Call For Submitting
Cases
	

Dr. Zhang, editor of the
PCSO Bulletin Case Report
column, sincerely invites you
to send your case-either
well treated or failed for any
reason(s)-to be featured in
an upcoming issue. This
column welcomes any cases
that cannot easily be found
in orthodontic textbooks,
where there is an element of
uniqueness regarding the malocclusion itself or the
treatment. The editor also welcomes any comments
or feedback on the published cases, preferably the
Case Report featured in the most recent issue. If you
have questions about submitting your case or
sending your comments, please contact me at
xingzhongzhang@atsu.edu.
Thank you,
John (Xingzhong) Zhang, DDS, MSD, PhD,
