Background: Gingival recession may result in aesthetically unfavourable effects, difficulty in plaque control, increased susceptibility to root caries, and dentin hypersensitivity.
Objective: The aim of this study was to compare the use of modified semilunar techniques with connective tissue and subepithelial connective tissue grafts (Langer) for denuded root surface coverage.
Methods: In this randomized clinical trial, fourteen localized recessions of Miller class I to II were treated in 5 subjects. Recessions were randomly treated with modified semilunar techniques (test group) and a subepithelial connective tissue graft (control group). Clinical parameters such as clinical attachment level (CAL), keratinized tissue width (KTW), probing pocket depth (PPD), vertical recession depth (VRD) and recession width (RW)were recorded at base line, 1, 3 and 6 months after surgery and healing index and the subject's satisfaction was evaluated. The repeated measure test and paired-sample t-test were used for statistical analyses by SPSS.
Results: Both methods showed significant improvement in clinical parameters. The healing index (HI) in the test group was a slightly more than the control group in Day 10.Aesthetic VAS (Visual Analogue Scale) levels in the test group were more than the control group in 1, 3 and 6months (test group, in 1 month 6.57±1.13, in 3 month 7.86±1.07, in 6 month 8.00±0.81. control group in 1 month 5.57±1.13, in 3 month 7.00±1.00, in 6 month 7.14±0.90). The KTW, CAL, VRD and RW level’s difference in the test and control group was significant in 6 month compared to the base line (p=0.000).
Conclusions: The present study shows that treatment of Miller Class I and II gingival recession by the modified semilunar technique is acceptable.
Clinical trial registration: The trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the Irct ID: IRCT201512021760N43. Date registered: December 27, 2015.

Ethics of Publishing Case Reports: Do We Need Ethics Approval and Patient Consent?
An editorial by Dr. Mehrdad Jalalian
The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.
To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here

Lessons from COVID-19 pandemic and the Morocco’s success story.
An editorial by Dr. Benksim Abdelhafid (Morocco)
The 6th World Conference on Research Integrity (WCRI) is to be held on June 2-5, 2019 in Hong Kong.
The WCRI is the largest and most significant international conference on research integrity. Since the first conference in Lisbon in 2007, it has given researchers, teachers, funding agencies, government officials, journal editors, senior administrators, and research students opportunities to share experiences and to discuss and promote integrity in research.
