3/13 JOP and JCP

Question 1

Describe the survey study on Periodontists and stem cell-based therapy for alveolar bone regeneration.

Kaigler et al. JOP

Answer 1

481 survey responses

Survey questions:
* have you heard of stem-cell grafting before?
* How have you heard about this?
* How interested are you to learn about stem-cell grafting in online CE, in-person CE, manual, other ways

RESULTS:
Most periodontists weren’t familiar with stem cell grafting. However, most were motivated to learn about it after hearing of it

Question 2

How does ChatGPT do on the periodontics In-Service exam?

Danesh et al. JOP

Answer 2

Tested ChatGPT 3.5 and ChatGPT 4 on the 2023 In-Service Exam.

ChatGPT4 was more accurate than ChatGPT3.5 in periodontal etiology, diagnosis, treatment planning, and prognosis.

Question 3

What are risk indicators for gingival recession in the esthetic zone?

Mascardo et al. JOP

Answer 3

37 patients
Cross-sectional study.
Examined clinical measurements, CBCT, intraoral scans and ultrasound.

Results:
Prevalence of Gingival Recession was 78% on a patient level, and 44% on a tooth level.
* 31% was RT1
* 38% was RT2
* 31% was RT3
Each additional 1 mm of KT reduced the risk of mid-facial recession by 38%.
Each additional 1mm of GT reduced the risk of recession by 82%.

Question 4

How are periodontal pockets predictors for site-worsening after nonsurgical therapy? - retrospective cohort study

Herz et al JCP

Answer 4

Long-term retrospective cohort study
116 patients
* over 75% of PD’s remained the same or worsened during nonsurgical therapy.
* PD’s increased in 37% of sites; remained the same in 41%; and decreased in 21% of sites.
* Worsening PD was significantly associated with distopalatal furcation involvement (OR = 2.5) , tooth mobility, and presence of residual pockets.

Question 5

Describe the 5 year results of single immediate implant placement into the maxilla with vs. without CTG grafting.

Zuiderveld et al JCP

Answer 5

RCT with 5 year followup
60 patients total

Results:
* Survival: 96.7% in both groups
* CTG group had +0.1mm marginal bone gain; control group (no CTG) had -0.6mm bone loss. = SSD
* NSSD in esthetic scores (measured by Pink Esthetic Score and White Esthetic Score).

Conclusion: Immediate implant placement with CTG appears to reduce recession and bone loss

Question 6

Describe the study on flapless early implant placement into the uncalcified provisional matrix.

Park et al. JCP

Answer 6

Early placement: 4-8 weeks after extraction.

6 mongrel dogs
Extracted the mandibular 1st molars
Four groups:
* Flapless placement into provisional matrix
* Flapless placement after removal of provisional matrix
* Flap and place with GBR
* Control (spontaneous healing only; no implant)

Histology taken at 3 months post-placement.

RESULTS:
* Complete bone fill in all groups.
* NSSD in bone-implant contact, marginal bone levels, connective tissue thickness.

CONCLUSION:
Early implant placement into the provisonal matrix (in dogs) appears to be just as good as placement with GBR and placement after removal of the provisonal matrix.
