Study of antibacterial and antifungal efficacy of platelet-rich fibrin and platelet-rich fibrin matrix

Nagaraja S, Mathew S, Jain N, Jethani B, Nambiar S, Kumari M, Nair S. Study of antibacterial and antifungal efficacy of platelet-rich fibrin and platelet-rich fibrin matrix. J Conserv Dent [serial online] 2019 [cited 2020 Aug 5];22:415-9. Available from: http://www.jcd.org.in/text.asp?2019/22/5/415/291315

Background: Platelet concentrates are extensively utilized in the medical and dental field to promote tissue regeneration. The profusion of endogenous growth factors in platelets α-granules transmit their use for enhanced wound healing. However, little attention has been given to study their antimicrobial potential. This study was conducted to assess the antibacterial and antifungal property of platelet-rich fibrin (PRF) and PRF matrix (PRFM).

Materials and Methodology: Blood samples were obtained from 16 participants, PRF and PRFM were processed as per the protocol prescribed by Choukroun et al. and Lucarelli et al., respectively. The susceptibility test against microbiota in the root canal and Candida albicans was assessed through minimum inhibition zone by agar diffusion technique.
Results: PRF showed an effective antibacterial property, however, did not perform well against C. albicans strains. PRFM did not show any antibacterial or antifungal properties.
Conclusions: The antibacterial efficacy of PRF may prove beneficial when used in the revascularization procedure of immature necrotic teeth.

Standardization of a cone beam computed tomography machine in evaluating bone density: a novel approach

. 2020 Aug 3.

doi: 10.23736/S0026-4970.20.04347-2. Online ahead of print.

Abstract

Background: Advent of Cone Beam Computed Tomography (CBCT) in dentistry has brought us to a new era of precise imaging. Radiographic evaluation of a CBCT image is more informational when compared to CT. The density measurements in CBCT images are based on greyscale values, which are more accurate in CT and these values are inconsistent across various CBCT machines. Hence, we aim at standardizing a single CBCT scanner to evaluate or determine tissue density from the greyscale values.

Methods: A total of 8 halves of undamaged, dry goat mandibles are included in the study. Scans of the bone are obtained using the KODAK CBCT unit and the PHILLIPS CT machine respectively. Densities are evaluated at 96 points on both the CT scans and the CBCT scans, respectively, using the Radiant Dicom viewer. The obtained data is entered into the excel spreadsheet and subjected to statistical analysis.

Results: The greyscale values are obtained from each of the CBCT scans. Hounsfield units are calculated from CT images coinciding with the same points on CBCT scans. The collected data is subjected to linear regression analysis and an equation is derived to determine Hounsfield units (calculated HU units) from greyscale values of CBCT images. We found no significant difference between the mean original HU units and the mean calculated HU units, thus making the equation reliable for calculating HU units from CBCT greyscale values.

Conclusions: Our results conclude that the technique was effective in calculating the Original density of tissues using grey standards of CBCT scans.

Child abuse and the role of a dentist in its identification, prevention and protection: A literature review

SINGH, Vishwendra; LEHL, Gurvanit. Child abuse and the role of a dentist in its identification, prevention and protection: A literature review. Dental Research Journal, [S.l.], v. 17, n. 3, jul. 2020. ISSN 2008-0255. Available at: <http://drj.mui.ac.ir/index.php/drj/article/view/2111>. Date accessed: 09 Jul. 2020.

Abstract

Child abuse, a reprehensible act, pervades all strata of society. Dentists are more likely to encounter
such cases in their daily practice. However, such cases usually go unreported due to lack of adequate
knowledge. Practitioners flinch from reporting these due to various reasons, and this sets up a vicious
cycle which traps the victim leading to grave long‑term consequences. This review aims to collect
all literature available on PubMed, PubMed Central, MEDLINE, Google Scholar, and Google search
engines on the role of dentists in child abuse identification and information and summarize these
details. The review will shed light on the identification of abuse in dental settings, the various legal
recourses and organizations related to it, and how dentists can better equip themselves to tackle
such cases if they come across one. The review also makes certain recommendations by which
dentists and healthcare providers in general can better prepare themselves for such contingencies.

The Use of PRF for Hard and Soft Tissue Grafting

T

Current Oral Health Reports (2020)Cite this article

Abstract

Purpose of Review

The use of platelet-rich fibrin (PRF), a second-generation platelet concentrate, has gained popularity in the field of oral regenerative surgery. This review presents data from published clinical trials on outcomes from PRF application in regeneration of infrabony defects, implant site development, and mucogingival surgery.

Recent Findings

When PRF is used for regeneration of infrabony defects, minor improvements are noted in the clinical parameters that in the majority of the cases does not reach the level of statistical significance. The use of PRF appears to limit the dimensional changes of the alveolar ridge after tooth extraction when compared with sockets that are allowed to heal with no grafting. When combined with coronally advanced flaps (CAF) for root coverage, PRF shows a slight advantage over CAF alone.

Summary

Despite the adequate volume of publications in the field, the limitations of the existing studies highlight the need for high level of evidence to support the significant benefit of PRF in hard and soft tissue within the scope of periodontal and peri-implant surgery.

GA School of Orthodontics Contest to Award Local Children Complimentary Orthodontic Care

ATLANTA, July 16, 2020 /PRNewswire/ — Georgia School of Orthodontics (GSO) announced that it will provide four additional Atlanta-based children with complimentary orthodontic care through its Gift of a Smile program. GSO established the Gift of a Smile program in 2016 to celebrate the grand opening of its Atlanta clinic. Since its inception, the program has provided free orthodontic care to thirteen (13) children in the metro Atlanta area, as part of the School’s pledge to provide $100,000 in complimentary orthodontic care to children who need braces but cannot otherwise afford it.

Dacula resident and 2020 high school graduate Sierra Henson is all smiles, and a former recipient of Gift of a Smile complimentary orthodontic treatment from Georgia School of Orthodontics. Go to www.bracestoday.com/gift to nominate someone to receive a Gift of a Smile. Nomination deadline is August 31, 2020.

Past recipients are grateful for the impact the program has had on their children’s lives. "It’s almost like night and day," said LaTresha McGowan, who raises Gift of a Smile recipient Solomon and his brother Philip with her sister, Rashuana McGowan. "Solomon used to mumble and hide his mouth behind his hand. He smiles all the time now, actively participates in family events, and seeks out new friends and new experiences."

For Decatur resident Oli Soler, a dental receptionist and mother of Gift of a Smile recipient Damian Soler, 16, it has been a wonderful journey. "Seeing his smile change and his confidence grow has been a blessing. The staff and doctors at GSO are amazing and we are so thankful for this incredible gift."

GSO’s Gift of a Smile is just one part of its mission to provide increased access to the highest quality orthodontic care at a lower cost than private practice orthodontics. GSO also has the Purple Heart Smiles program, which provides free orthodontic care to the children of Purple Heart recipients. To date, GSO has provided over twenty-four (24) children of Purple Heart recipients with complimentary care.  Both programs combined have provided more than $125,000 in complimentary orthodontic care to Atlanta’s deserving children.

"Increasing the access to orthodontic care is a core part of our mission here at the Georgia School of Orthodontics. We are honored to provide these deserving children with free orthodontic care. We hope that we can in some small way alleviate the financial burden and stress that COVID-19 has caused local families," said Dr. Randy Kluender, President of the GSO Board of Trustees.
