Question 1

Costa.. effect of supraG plaque control on reccurent Perio & stability..10 Years FU

Answer 1

Aim:
Evaluate the effect of supraginval plaque control on the recurrence of periodontitis and the achievement of a stable periodontal clinical endpoint after 10 years of periodontal maintenance therapy

Retrospect.
categorized OH px acc. to plaque index –> Good , fair, pair
collected data at
T1 –> PRIOR to active Tx
T2 –> after actove Tx
T3 –>10 yrs after

Result:
- SSD in all periodontal clinical parameters between the 3 different oral hygiene groups at T3. NSSD differences at T1 and T1.
- Poor OH group exhibited higher mean BOP, PD, CAL, and higher tooth loss (POH > FOH > GOH)

• increased risk of recurring periodontitis in the FOH (OR: 2.02), POH (4)
• FOH and POH had an approximately 2.5 and 6.0 times greater chance of not achieving a stable clinical endpoint

Question 2

Li effect of life course adiposity and PD

Answer 2

Aim: To establish whether life course adiposity, including birth weight (BW), childhood and adulthood body mass index (BMI), waist–hip ratio (WHR), and body fat percentage (BF%), has a causal influence on periodontitis.

Methods:
- data from GWAS and MA

Results:
Positive findings between BMI & BF% and PD
Conclusion:

New proof supporting a causal effect of increased adiposity, especially high BMI and BF%, on higher periodontitis risk.
* It yields new recommendations for the precise prevention of periodontitis, where overweight and obese people can aim to lower their periodontitis risk by reducing adulthood BMI and BF%.

Question 3

Basma… effect of bone particle size on outcomes of lateral GBR

Answer 3

AIM: compare the amount and quality of bone gained after lateral ridge augmentation with either small-particle size vs large particle size corticocancellous bone allografts

M&M:
22 Px , ridge width < 5 mm , andomly assigned to SP- and LP-size grafts, months, changes of crest dimensions were assessed radiographically (CBCT) and clinical + bone core

Results:
LP size graft resulted in greater ridge width gain at the level of the crest , and 4 mm apical to the crest: (NSSD)
5.1 ± 1.7 mm (LP) vs 3.7 ± 1.3 mm (SP)
5.9 ± 2.2 mm (LP) vs 5.1 ± 1.8 mm (SP) .
But no sign differences between both groups in both cases
* Vertical changes at crest, NSSD: -0.4 ± 0.5 mm (SP) +0.3 ± 1.0 mm (LP)

biggest flaw: study is hugely underpowered due to low sample size. There could SSD had they used larger sample size

Question 4

Kwoen - association between PD, Ext and MRONJ

Answer 4

LITTLE CONFUSING

AIM: Whether periodontal diseases contribute to the development of MRONJ) in addition to tooth extraction, which is a major risk factor for MRONJ occurrence?

• Conclusion:
  Background & Aim
  Material & Methods
  Results

Conclusion & Critique
The results showed that periodontal disease and tooth extraction were independently associated with the onset of MRONJ. Furthermore, the risk of MRONJ tended to increase when tooth extraction was performed in patients diagnosed with periodontal disease.

Question 5

Thoma VCMX for soft tissue aug at implants 5 year results of RCT

Answer 5

Aim:
Assess 5-year data on clinical and radiographic outcomes at implant sites previously augmented with a volume-stable collagen matrix or an autogenous connective tissue graft

Measurements:
- Mucosal thickness: Endodontic file inserted 1 mm apical od the mucosal margin buccal
- Ridge contour changes: Dental impressions, scanned with lab scanner, analyzed with digital imaging software program

Results:
The median buccal mucosal thickness increased by 0.3 mm (VCMX) and 0.5 mm (SCTG). Changes were not significant.

Question 6

Answer 6

conduct a retrospective study comparing the groups above (smokers, vapers, non-smokers) in response to treatment

Question 7

Answer 7

VIP

Aim: to analyze the effet of autogenous blood products, EMD, rhPDGF and bmp2 in ARP

SR oF RCTs

No clinical benefits

Question 8

Siu Flap vs Flapless ARP

Answer 8

AIM:
Compare a flapless technique of alveolar ridge preservation to a flap technique to determine if the preserving of the periodosteal blood supply would limit loss of crestal ridge width and height

RESULTS:
- ridge width at the crest –> NSSD
- Decrease of midbuccal vertical height –> NSSD
