Question 1

Chambrone, Avila-Ortiz

Answer 1

JOP - An evidence-based system for the classification and clinical management of non-proximal gingival recession defects

Aim: to create a classification system that took into consideration determinants of treatment (AG and MT - Miller/Cairo dont) and could be correlated with suggested treatments

GRD 1 / 2 / 3 - Same as RT-1 / 2 / 3

Subtype A - >1mm AG : >1mm MT
Subtype B - >1mm AG : <1mm MT
Subtype C - <1mm AG : <1mm MT

Question 2

Berglundh (Romandini, Derks, Sanz, Berglundh T)

Answer 2

COIR - Clinical findings and history of bone loss at implant sites

Aim: Are clinical parameters (PPD and BOP) related to experience of bone loss?

600pts 2000 implants

PPD and bone loss:
+1mm PD = +0.3mm bone loss
Low sensitivity, High specificity
PPD _>_6mm = 18-38% chance boneloss (sensitivity)
No PPD _>_6mm = 92-94% chance NO bone loss (specificity)

• *BOP and bone loss:**
• *High Sensitivity** for >2mm MBL when _>_1 bleeding site (80.9%)
• *High Specificity** for >2mm MBL when _>_3 bleeding site (80.3%)

Question 3

Cardoso

Answer 3

JCP - Late complications after root coverage with 2 types of sCTG, clinical and histopathological evaluation: prospective cohort study

Late complications: keloids, root resorption, exostosis, white/yellow discharge + gingival cul-de-sac
no data on rate/period of occurrence

de-epiFGG and sCTG

n=64 133rec

Results:
6 Cul-de-sac cysts - 2 histo
NSSD in complications rate between de-epi vs sCTG
Secretion usually only when provoked
Most happen at 6mo (3-12)
Histologically - deep invagination/downgrowth of epithelial lining into CT graft (duct)
True cysts lined with cuboidal epi cells
epithelial islands

Question 4

Tiensripojamarn (Tine-sri-poj-amarn)

Answer 4

What is the association between perio and the incidence of CVD in Thai adults?

Prospective study
12 year mean observation
1850 participants
75% male - high education (50% bachelors)

52% moderate disease (AL _>_4mm PD _>_5mm at 2+ non proximal)
35% severe disease (AL _>_6mm, or 1 PD _>_5mm
12% mild disease (AL _>_3mm PD _>_4mm or 1 PD _>_5mm)

CVD incidence increased with severity of disease - NSSD when adjusted HR
Coronary Heart Disease: Sig. association with mod and sev - only severe when adjusted HR (4.53)
Stroke: No association with severity

Severe perio is associated with increased incidence of CHD independent of traditional risk factors

Question 5

Costa

Answer 5

Effect of compliance during perio maintenance on c-Reactive Protein levels

Perio exam/plasma sample/Elisa to quantify CRP levels

Regular compliers (RC) and Irregular compliers (IR)

T1: Prior to therapy
T2: 45-60days after
T3: 6yrs after

T1: NSSD btw groups
T2: Sig reduction in both (perio therapy reduces inflammation)
T3: IR sig higher levels of CRP

Disease recurrence: 2.19x CRP
Irregular compliers: 2.85x CRP
Obese individuals: 3.73x CRP

Higher CRP was associated with higher recurrence and worse clinical parameters

Question 7

Hyer (Mealy)

Answer 7

Do image enhancements help to identify calculus in radiographs

NSSD in improvement of detection with different enhancements

Caclulus detection improved when root surface covered by >30%

Question 8

Vallim (Albander, Haas)

Answer 8

Is obesity a risk factor for tooth loss? 5yr cohort of brazilian population

Baseline & 5yr follow up
BMI and changes in obesity included

n=~650

Obesity at baseline increased risk in Female sex, Hx of perio, Smoking

Females: RR 1.48
Hx of Perio: RR 1.51
Hx of Smoking: RR 1.53

Remaining overweight also increase RR about the same

Obesity is a risk factor
Obese females, individuals with perio, and smokers deserve major attention
