Bertl (Stavropolous) et al. 2021
Reliability of Colored Periodontal Probes
Cross Sectional - 50pts - 3Ant teeth
Studer et al. 1997 - Transgingival sounding accurate to within 0.5mm
Results
INTERexaminer reproducability:
SPP (agreement 0.42)
Visual (agreement 0.21)
CPP (agreement 0.11)
Intra-examiner repeatability:
visual judgement (fair to moderate)
SPP (slight to substantial)
CPP (poor to moderate for white, fair to substantial for green, perfect
for blue)
ALL had high PPV ~0.82 for identifying THICK
ALL had high FALSE OMMISSION RATE (FOR) ~0.70
CPP: 88% False Positive for Thin
SPP: 64% False Positive for Thin
Methods
Cross sectional (50pts 3teeth each)
Buccal GT measured by 4 methods
Visual judgement, Standard probe transparency (SPP) Colored probe transparency (CPP), Transgingival sounding (1mm below GM), 1-3 judged through photos, 4 gold standard
8 examiners
Ongphichetmetha et al. 2021
Bioactive glass vs Arginine dentifrice for hypersensitivity - RCT
Results
NSSD between groups
Immediate reduction was more than control, but by 8wks, all equil
Methods
RCT
Bioactive glass (Calcium Sodium Phosopho Silicate - sensodyne)
Arginine
Control
Schiff score (0-3 -nothing/notice/notice dont stop/stop)
VAS
Espindola et al. 2021
Prevelence and antimicrobial susceptbility of gram - bacilli in sub g biofilm of perio
Results
Periodontitis samples had more Gram - than Healthy/Gingivitis
NSSD in antimicrobial susceptibility
EXCEPT Cephtriaxone (3rd gen abx) which Health had more resistant strains
Methods
SubG sample
Cultured
Abx susceptibiltiy test
Excluded smokers or people who quit <10yrs ago (Tomar & Asma (11yrs) - but should have used Ravida)
Camargo et al. 2021
Effect of Infrared Laser on Vitro and Vivo Perio
Infrared light laser therapy can induce analgesic,
anti-inflammatory, and biomodulatory effects by
acting on microcirculation and cellular activity,
Results
PDL group had better trabecular thickness and closed porosity%
48 Rats
3 groups: Control, Periodontitis (PD), Periodontitis Laser (PDL) groups
Ligature induced
PDL group had infrared light laser for 30days
Dowlatshahi et al. (Machtei)
GBR w/ FDBA and membrane vs OssixVolumax (crosslinked collagen scaffold)
35pts - Baseline CBCT - FTMPF, corticotomy, then one of the methods. 9mo reentry and CBCT
OV caused slight bone resorption - not good on its own
Ridge width:
2mm apical - -0.6mm
5mm apical - -0.4mm
8mm apical - -0.1mm
FDBA had slight bone gain
0.9mm
0.9mm
-0.04mm
OV not suitable on its own
