anatomy of periodontium
what fibers prevent extrusion of the tooth?
alveolar crest fibers
what is probing depth?
distance between gingival margin and base of sulcus/pocket as detected by periodontics probe
what is a major virulence factor that leads to gingivitis?
gingipains
what is the pathophysiologic mechanism of Paget's disease?
increased osteoclastic activity
where do we have the least amount of attached gingiva?
1st premolar area (max + man)
what are the contents of a periodontics probe?
mirror
perio probe
nabers probe
explorer
when we do Endodontic treatment do we lose proprioception? explain.
no dont lose proprioception because proprioception is related to PDL we only lose feeling of hot and cold
where do we find the least amount of pigmentation?
tongue
what are common errors in probing and inter proximal probing?
probing = point probing
inter proximal = line angle + vertical interproximal
differentiate between gingivitis and periodontitis.
gingivitis: inflammation of the soft tissue
periodontitis: inflammation + attachment loss + bone loss (depends on dysbiosis + susceptible host)
what is passive eruption?
tooth erupts then you have apical migration the gingiva
name 4 findings you can find on root surface detection.
smooth root
calculus
caries
irregular restorative margin
what are the functions of the PDL?
soft tissue casing to protect neurovasculature from injury by mechanical forces
transmits occlusal forces to bone
attach teeth to bone
maintain proper relationship between teeth and gingival tissues
shock absorption
explain the different classes of the miller index for mobility
class 0 no movement
class 1 <0.5mm in 1 direction /<1mm in both
class 2 0.5-1mm in 1 direction/1-2 mm in both
class 3 >1mm in 1 direction + vertical depressibility/ >2mm in both + vertical repressibility
