Scope and policy

CHARACTERISTICS AND OBJECTIVES. The “Revista Clínica de Periodoncia, Implantología y Rehabilitación Oral” (PIRO) is a scientific publication about periodontics, osseointegration, rehabilitation and other specializations directly related with them.

PERIODICITY. The “Revista Clínica de Periodoncia, Implantología y Rehabilitación Oral” (PIRO) is four-monthly published, in April, August and December every year.

ANNOUNCEMENT. All the specialists in Periodontics, Implantology, Oral Rehabilitation and other related specializations, nationals and foreigners, are called to present their works to be published in PIRO, in its three permanent sections, namely: Investigation works, Clinical Reports and Bibliographic revisions.

ORIGINALITY. Only original and unpublished works sent by the authors, in the specializations of Periodontics, Implantology, Oral Rehabilitation and the other directly related specializations will be accepted for publication. The sending of an original document involves a commitment from the author not to submit it simultaneously to other periodic journals.

COPYRIGHTS. The sending of the original document involves that the author transfers all the copyrights to PIRO, once the publication is accepted.

WORKS SELECTION. The studies and essays will be checked by the Redaction Council and by the Director of the Journal. Subsequently the investigations will be submitted to an arbitration system, which means the assessment by two external referees, whose mission is limited to provide the guidelines which guarantee the objectivity and the double anonymity in their verdict. In case of a divergence in the arbitration, a third assessment will be asked. As for the designation of the referees, the academicians with a Doctor grade in their respective specializations will be favored. They will be appointed every year in a list drawn up by the Editorial Council and the Redaction Council. According to the result of the arbitrations, the “PIRO” reserves the right to accept or deny the publication of the received works, as well as to suggest to the author(s) changes of form without changing the content of the work.

OFFPRINTS. The contributors whose works were accepted and published in PIRO, will receive a free copy containing their work.

Form and preparation of manuscripts

The scientific magazine of Periodontics, Implantology and Oral Rehabilitation (PIRO) will publish scientific or practical articles about periodontics, osseointegration, rehabilitation and directly related specializations. The editorial board will strictly follow these guidelines; The articles not following them will be returned for correction, before considering their publication.

The sent articles must be original, must not have been sent to another publication and the author will be the only responsible for the statements included in it.


  • Original articles contributing with new clinical or research data related to the specialization. Properly summarized articles can be published quickly as short communications.
  • Revision articles updating a concrete theme from the scientific and objective point of view. Usually the revisions will be ordered by the editor to specialists in the area of interest. They mustn’t exceed 5.000 words, 100 bibliographical references or 6 tables or figures. Authors interested in collaborating in this section should contact the editor and ask for the adaptation and originality of the proposed theme.
  • Clinical reports or clinical cases. Unusual reports or reports contributing with new therapeutic concepts will be published. The clinical and iconographical information and the complete pre, post operatory and monitoring information must be included. Besides, the treatment carried out must be clearly explained. The text must be brief, less than 6 pages, and the bibliographical references must be confined to what is strictly necessary. Sequences of photos of multidisciplinary treatments of complex cases or surgical techniques will be especially interesting. The author will be oriented by the editor on the selection and quality of the photographic material.
  • Letters to the editor offering comments or constructive critics about previously published articles or other topics of interest for the reader. They must be succinct and centered on a specific topic and they must be signed. The bibliographical references, if present, have to appear in the text between brackets. In case of comments on an article published in this journal, the author of the article will have the opportunity to answer.


Only those individuals who contributed significantly to the development of an article will be considered as authors and as such, they will assume the public responsibility of its content. Significant contribution means to fulfill the three following conditions: 1) take part in the development of the work concept and design, or in the analysis and interpretation of the data; 2) contribute to the fundamental writing or revision of the article; 3) collaborate in the final supervision of the published version of the article. The mere participation in the funds raising or in the data collection doesn’t justify the authorship of the work, neither the general supervision of the research group. The editor can demand to the authors to justify their quality as such. The collaboration of the persons who contributed to a lesser extent will be thanked in the acknowledgement section and their names will have to be sent in a separate page.

All the authors will have to sign a cover letter enclosed to the article and will have to state the acceptance of the publication norms of the Clinical Journal of Periodontics, Implantology and Oral Rehabilitation (Revista Clínica de Periodoncia, Implantología y Rehabilitación Oral).


The manuscripts must be sent through the online platform in the web page of the Clinical Journal of Periodontics, Implantology and Oral Rehabilitation (Revista Clínica de Periodoncia, Implantología y Rehabilitación Oral) (, of the Chilean Periodontics Society  (Sociedad de Periodoncia de Chile) (, of the Chilean Prosthesis and Oral Rehabilitation Society (Sociedad de Prótesis y Rehabilitación Oral de Chile) ( and of the Chilean Oral Implantology Society (Sociedad de Implantología Oral de Chile) (
