Non-English-speakers had been required to submit the certification of English proofreading by native, but it would become unnecessary on March 1st, 2015. Each author should be responsible for English proofreading.

Along with this modification, the third and fourth term in Instructions for Authors will be changed as follows.

Manuscripts should be conforming to Dental Materials Journal style and have English language errors corrected before submission. The editorial board may return the manuscript without refereeing due to the poor style and language usage. In the case of authors who are not native speaker of English, before submission, English grammar and syntax in the manuscripts should be checked and corrected by a native English-speaking person.

All authors would be greatly appreciated to polish English deliberately during the review process.
