OHS IV FINAL EXAM QUESTIONS AND ANSWERS
Different types of grafts - CORRECT ANSWER✅✅*Autograft*: taken from own body
*Allograft*: taken from another human (usually cadaver)
*Xenograft*: taken from another species (ie. cow)
*Alloplast*: synthetic bone
Hyperimia of the pulp - CORRECT ANSWER✅✅Injury to pulp
--> arterioles in pulp become engorged and dilate
--> can cause discoloration in non-vital tooth due to hemorrhage of blood going into dentinal tubules
Pulpitis - CORRECT ANSWER✅✅inflammation of dental pulp
Pulpal necrosis - CORRECT ANSWER✅✅death of dental pulp, as a *result of pulpitis*
Periapical Granuloma - CORRECT ANSWER✅✅tumor-like mass made up of *granulation tissue*
-occurs as a result of the bone that it replaces
Treatment:
-removal of irritant from root canal
--> tissue then repairs
--> then converts into normal periapical tissue
Prognosis: good
*Denticles* (pulp stones) - CORRECT ANSWER✅✅calcified substances occurring in the *coronal*
portion of the *pulp*
-can be seen on x-rays
-classified by their development or histology
,-may be composed of *dentin* or *irregularly calcified tissue*
-*50%* of newly erupted teeth
-*90%* of older teeth
-may cause pain if they impinge on nerve tissue
How can denticles cause pain? - CORRECT ANSWER✅✅if the calcifications impinge on nerve tissue
"True" pulp stone - CORRECT ANSWER✅✅a calcified body containing *tubular dentin* and
*odontoblasts*
-exhibits radiating striations that look like dentinal tubules
-these are rare
"False" pulp stone - CORRECT ANSWER✅✅Consists of concentric layers of *degenerated or irregularly
calcified tissue*
-does not bear much resemblance to any known tissue
-DON'T contain dentinal tubules
Periapical Cyst - CORRECT ANSWER✅✅Fluid filled sac lined w/ epithelial cells
*Location*: in the bone at the apex of a *pulpless tooth*
-may increase in size--> cause *pressure* --> cause bone loss and tooth mobility
What is the risk if apical periodontitis doesn't get treated? - CORRECT ANSWER✅✅-Infection travels in
tissue spaces --> can become cellulitis or something worse like Ludwig's Angina
-can cause Periapical Abcess
T/F
Periodontal surgery does not increase the risk of caries - CORRECT ANSWER✅✅F
Periodontal surgery generally can increase risk of caries
, Vertical Dimension - CORRECT ANSWER✅✅The distance b/t maxilla and mandible when the *mandible
is at rest*
Centric Occlusion - CORRECT ANSWER✅✅*voluntary*, habitual biting position of teeth which allows
*maximum contact* of the max and mand teeth when closed
Centric Relation - CORRECT ANSWER✅✅-a centralized position of the condyle w/in the glenoid fossa
-condyle is slightly to the top and back of the glenoid fossa
-evaluated when teeth are slightly apart and again when teeth are closed
Child *neglect* - CORRECT ANSWER✅✅refers to physical or emotional *negligence* of a child
-usually represents a case of *omission*
eg. failure to provide food, health, medical/dental care
-untreated rampant caries
-untreated dental pain
-infection
-pathology
Child *abuse* - CORRECT ANSWER✅✅any physical, sexual, or emotional abuse against a child
-dental professionals, by law, must report suspected cases of child abuse or neglect to authorities
eg.
-observed fearfulness
-withdrawn
-watchful/jumpy
-no eye contact or spontaneous smiles
-intraoral lesions
-bruises on extremities
