Use of platelet-rich fibrin versus connective tissue graft in treatment of gingival recessions: Literature review



Material and methods: A systematic literature review was performed of randomized control trials in English identified in MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (Cochrane Library), Springer Link, Science Direct and Google Scholar databases, published between 2015 and 2020. Studies had to be performed in vivo with follow-up periods of ≥6 months.
Results: 153 publications were found, out of which 8 were identified as relevant to the theme. Six of these studies evaluated periodontal parameters such as probing depth (PD), clinical attachment level (CAL), recession depth (RD), keratinized tissue width (KTW) and gingival thickness (GT). In 3 studies discomfort and aesthetic scores were analyzed as subjective parameters. 1 study histologically evaluated different techniques of gingival recession treatment.

Conclusion: Both techniques are effective in the treatment of Miller’s class I and II gingival recessions. Although the CTG technique may provide better results in KTW and GT, PRF avoids a donor site, which means a major decrease in postoperative discomfort.

Dentists from RUDN University found a reason for early deterioration of dental implants


Research News




A team of dentists from RUDN University confirmed that a change in the dominant side of chewing is a reason for the early deterioration of dental implants. Such a change makes it more difficult for a patient to get accustomed to an implant and can lead to bone tissue abnormalities. The discovery can help dentists plan the recovery process after implantation surgeries. The results of the study were published in the European Journal of Dentistry.

Every year, around 2 mln dental implants with fixed dentures attached to them are installed all over the world. An implant is an effective way to restore a deformed or lost tooth without negatively affecting a patient’s quality of life. Modern-day dental implants, usually made of titanium, are durable and quick to take in the bone tissue of a jaw. The only issue with them is their early deterioration in 4-5% of patients. Such deterioration is caused by microdamage that occurs when the load on the implant is calculated incorrectly before the surgery. Excessive load affects the junction between the metal and the bone, letting the bacteria in under the implant and causing inflammation. A team of dentists from RUDN University suggested that additional load on the implant might occur when a patient changes the dominant side of chewing in the first months after the surgery.

Most people don’t chew symmetrically on both sides of the jaw but have a dominant side that accounts for up to 75% of chewing movements. However, such a side can be changed, for example, because of a sore tooth. It usually takes a patient 3 to 4 months to get accustomed to a dental implant and during this time the type of chewing and the load on the teeth can change. As a result, after the surgery, a patient can switch to a different side of chewing, and load calculations from before the surgery can become invalid. Until recently, the effect of this dramatic change in chewing habits on the state of dential implants remained understudied.

The team monitored the course of rehabilitation of 64 patients with dental implants. The participants of the study were adults with implants installed only on one side of the jaw. Surgeries on both sides of the jaw were not included in the study as they would not allow for measuring the effect of dominant chewing side change. The team took X-ray images of the participants’ teeth, measured the strength of their chewing muscles, and in some cases took CT images of the jaws. All these operations were conducted once before the surgery and twice within a year after it. To analyze the results of the treatment, the team asked the participants to fill in questionnaires.

40 patients (62.5%) reported changes in the dominant side of chewing after the surgery. According to the dentists, this might have happened because the patients returned to the chewing patterns they had been used to earlier, before losing a tooth. Having compared this group with the rest of the patients that reported no changes in their chewing habits, the team found out that a change of the dominant side of chewing leads to more bone tissue formation pathologies. In 4 patients with changed chewing habits, the first signs of issue deterioration around the implant were visible in X-ray images. As for the second group, these signs were identified in only one participant. Six months after the surgery the patients that changed their dominant side of chewing felt 22% less adapted to the implants than the patients with no changes in their chewing patterns.

"A change in the dominant side of chewing is an important factor in one’s adaptation to dental implants. According to our study, it can also be the reason for pathological processes, eventually leading to the loss of an implant. Dentists need to be aware of the prevalence of such changes, consider them when developing postsurgical rehabilitation plants, and look for their signs during regular checkups," said Prof. Igor Voronov, MD, from the Department of Orthopedic Dentistry, RUDN University.

Dentistry Today Names Dr. Paul Feuerstein Editor-in-Chief

Dr. Paul Feuerstein will succeed Dr. Damon Adams, who is retiring at the end of December.

FAIRFIELD, NJDentistry Today, the nation’s leading clinical news magazine for dentists, proudly announces the appointment of Paul Feuerstein, DMD, as Editor-in-Chief. He will succeed Damon Adams, DDS, who is retiring December 31.

“It has been an honor and privilege to serve as the Editor-in-Chief of Dentistry Today since 2008. I often said that the best part of my work here at the publication was not the editing, but rather the blessings in life that come from serving and working with others,” Adams said.

“Dr. Paul Feuerstein, who has faithfully served Dentistry Today for a number of years now as our Technology Editor, will be taking over at the helm of the editorial team.”

Feuerstein will begin his new role with the January 2021 issue. 

“My passion for new equipment, new products, and how things work has played a major role in my entire dental career. I spend an inordinate amount of time at dental meetings and online talking to colleagues and manufacturers, as well as reading literature, to continue learning about the profession. My patients have been the primary beneficiaries of this quest, but my secondary passion is sharing this information with all of you through writing, lecturing, and meetings,” Feuerstein said.

“The opportunity to have Dentistry Today as a forum caps off many years of private practice, which I continue to do, and provides a chance to explore all things that run a dental practice—from the high tech to sealants and prophys,” Feuerstein said. “I hope you will all join me in this new adventure.”

Dentistry Today is excited to see what Dr. Feuerstein, given his love and passion for digital technology, brings to the publication’s print and online presence and how he will expand its reach in the dental community.

Inhalation Sedation During the COVID-19 Outbreak: An Expert Opinion

. 2020 Oct;22(10):533-535.


Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the pathogen that causes coronavirus disease-2019 (COVID-19), is thought to be transmitted via droplets and aerosols, and was detected in saliva of infected individuals. These droplets from the upper airway may infect the inhalation sedation mask and tubing. The authors determined the adequate measures needed to prevent the transmission of COVID-19 by nitrous-oxide (N2O) system during inhalation sedation in dentistry and provided evidence on mask and tubing sterilization. Additional measures to protect patients and healthcare workers from COVID-19 that may be transmitted by the inhalation sedation system are discussed. The authors recommend minimal use of a N2O system during inhalation sedation in dentistry. In case of need, the practitioners should have more than one scavenger kit and nasal masks for each N2O/O2 mixer. Biologic barriers should be mounted between the scavenger’s tubing and the central evacuation system. Strict cleansing and sterilization should be performed for all parts of the N2O system. The use a disposable scavenger system and nasal mask should be considered as a viable option.

Cone-Beam Computed Tomography (CBCT) Imaging for the Assessment of Periodontal Disease


Purpose of Review

Cone-beam computed tomography (CBCT) imaging has become a significant imaging modality in periodontology, and its applications to dentoalveolar disease and conditions are frequently updated. This review highlighted some of the current evidence of the use of CBCT scans for imaging the most common conditions related to periodontal diseases.

Recent Findings

CBCT imaging should not be the first choice for the routine assessment of vertical or horizontal bone loss, and its use should be preferable for cases where clinical information and conventional 2D images are insufficient or unclear for diagnosis and treatment decision. On the other hand, the use of CBCT appears to be prudent for an accurate diagnosis of furcation defects in patients with advanced periodontal disease, and in cases where dehiscence and fenestration are suspected. Should volumetric evaluation of those periodontal bone defects be required, it is important to use small voxel sizes for a more accurate measurement.


CBCT exams provide little additional benefit in the decision-making and disease managing in most cases of periodontal disease, being advocated only on patient-specific situations involving more complex conditions such as alveolar defects with intricate morphology, dehiscence, and fenestration.
