Round 1

Reviewer 1 Report

The manuscript shows promising antibacterial effects of a Bioactive Healing Abutment against periodontal pathogens. Therefore, I recommend this article for publication after considering the following modifications.

  1. Figure 1, please increase the font sizes in blue boxes to increase the understanding.
  2. Swelling and redness decreased in patients after having BHA coated with Clindamycin. Was this effect because of the anti-inflammatory properties of Clindamycin, or was there a reduced bacterial number that led to a decrease in these inflammatory signs?
  3. Line 352-354, the authors report an increase in P. gingivalis in three patients despite having BHA. What was reason behind an increase in bacterial number? Was there any role of food behind this? Hopefully, there was a controlled release of Clindamycin from BHA in this situation.
  4. Line 353, remove this before the pathogen.
  5. Authors are advised to provide a general recommendation about the use of BHA. Considering their benefits and antibacterial activities, should BHA be routinely applied in patients?
  6. BHA did not show strong effect against some bacteria, do authors suggest to include a combination of antibiotics in BHA instead of using a single antibiotic?
  7. Please make references, 5,11,13,31, and 32 similar to other references.

Reviewer 2 Report

Manuscript of considerable interest for the dental sector, a major revision is required before evaluating a possible publication

 

Abstract, highlight statistically significant data

 

Few keywords: add specific ones

 

Introduction: how does the oral microbiota change in the implant patient? Add reference from Prof Scribante

10.3390/app12073250

Materials and methods: how was the sample size calculated?

 

Results: very confusing, highlight statistically significant data

 

Discussion: Add proactive action using natural substances to reduce the incidence of pathogenic microorganisms as future goals
