These experiments aimed to investigate and compare the nature of the zone of secondary damage in calvarial bone defect prepared with either XeCl excimer laser or the erbium: YAG laser light at 75mJ/pulse. Material & Methods: These experiments were conducted in vitro, using excised calvarial bone, which was examined by environmental scanning electron microscopy (ESEM). Results: The excimer laser produced a morphologically different defect in bone. It was smooth surfaced with extensive scattering of debris and cracking. Were the Erbium: YAG laser slot showed less charring than XeCl excimer laser and the surface was smooth with microspheratic pattern. Energy dispersive x-ray analysis showed that the carbonisation and Ca/P ratio were higher in XeCl excimer laser defects compared to erbium: YAG laser defects.

Editorial Policy
The publication of an article in a peer reviewed journal is an essential model for Libyan journal of medical Research (LJMR). It is necessary to agree upon standards of expected ethical behavior for all parties involved in the act of publishing: the author, the journal editorial, the peer reviewer and the publisher.
Any manuscript or substantial parts of it, submitted to the journal must not be under consideration by any other journal. In general, the manuscript should not have already been published in any journal or other citable form, although it may have been deposited on a preprint server. Authors are required to ensure that no material submitted as part of a manuscript infringes existing copyrights, or the rights of a third party.
Authorship Policy
The manuscript authorship should be limited to those who have made a significant contribution and intellectual input to the research submitted to the journal, including design, performance, interpretation of the reported study, and writing the manuscript. All those who have made significant contributions should be listed as co-authors.
Others who have participated in certain substantive aspects of the manuscript but without intellectual input should only be recognized in the acknowledgements section of the manuscript. Also, one of the authors should be selected as the corresponding author to communicate with the journal and approve the final version of the manuscript for publication in the LJMR.
Peer-review Policy
- All the manuscripts submitted to LJMR will be subjected to the double-blinded peer-review process;
- The manuscript will be reviewed by two suitable experts in the respective subject area.
- Reports of all the reviewers will be considered while deciding on acceptance/revision or rejection of a manuscript.
- Editor-In-Chief will make the final decision, based on the reviewer’s comments.
- Editor-In-Chief can ask one or more advisory board members for their suggestions upon a manuscript, before making the final decision.
- Associate editor and review editors provide administrative support to maintain the integrity of the peer-review process.
- In case, authors challenge the editor’s negative decision with suitable arguments, the manuscript can be sent to one more reviewer and the final decision will be made based upon his recommendations.
