Questions and Answers List

level questions: HARD TOOTH TISSUE REDUCTION

Question	Answer
gradual wearing of tooth tissue due to physiologic factors such as mastication or speech	ATTRITION
Attrition is caused by	tooth-to-tooth contact
affects Only prominent on the incisal or occlusal third of the tooth or on the proximal surface of the tooth	ATTRITION
attrition Classification according to location:anterior teeth (centrals, laterals and canines)	Incisal attrition
attrition Classification according to location:Specifically the incisal thirds of the tooth	Incisal attrition
attrition Classification according to location:For posterior teeth	Occlusal attrition
attrition Classification according to location:Drifting towards the mesial	Proximal attrition (drifting and mastication)
the teeth tends to drift mesially over time	Physiologic mesial drifting
Clinical Manifestations of Attrition	Slight flattening of incisal edge
Over time, we lose the mamelons or the scallop edge of incisors because of attrition	Slight flattening of incisal edge
etiology of attrition: Loss of _____ resulting to shortening of bite and incisal attrition	posterior teeth
etiology of attrition: If the patient lose posterior teeth due to extraction, the tendency is for the patient to chew on anteriors	Loss of posterior teeth resulting to shortening of bite and incisal attrition
etiology of attrition: When the bite collapses or shortens in height because of the loss of posterior teeth	Shortening of bite
etiology of attrition: The occlusion is held together by the posterior teeth, therefore when they are extracted the bite ____	shortens
etiology of attrition: Chewing of ____ food	fibrous
etiology of attrition: ____or night grinding	Bruxism
etiology of attrition: incomplete or defective formation of the organic matrix of the enamel making it very soft	Hypoplasia
treatment of attrition: Mild attrition	no treatment needed
treatment of attrition: Moderate attrition	veneers or jacket crowns
Are the teeth sensitive when they undergo attrition	Not so much
what could be the reason why teteh arent so sensitive in attrition?	dentinal tubular sclerosis
Pathologic wearing of tooth structures through mechanical process	ABRASION
Wear of the tooth is caused by abrasive external agents	ABRASION
Can be toothbrush, tooth paste or dentures	ABRASION
location: On the cervical thirds of the root	ABRASION
location: It is also present most often with conjunction with gingival recession	ABRASION
location: It may affect both the enamel and dentin	ABRASION
clinical significance of abrasion	difficult to do endodontic treatment (RCT)
Defense mechanism of dentin during abrasion	To form secondary dentin
may obliterate the root canal	secondary dentin
Types of Abrasion:Often with gingival recession	Toothbrush Abrasion
Types of Abrasion:V-shaped / wedged-shaped cervical 3rd	Toothbrush Abrasion
Types of Abrasion:Sharp angled lesion and enamel edge	Toothbrush Abrasion
Types of Abrasion:Hard and highly polished dentin	Toothbrush Abrasion
Types of Abrasion:Most commonly found on adults, because of too much pressure and direction (horizontally)	Toothbrush Abrasion
Types of Abrasion:Notching of teeth	Occupational abrasion
Types of Abrasion:Carpenter, tailors, shoemakers	Occupational abrasion
Types of Abrasion:When they bite the nails	Occupational abrasion
Types of Abrasion:Pipe-smoking	Habitual abrasion
Types of Abrasion:Improper use of toothpick (proximal)	Habitual abrasion
Types of Abrasion:Rare: rituals like fire-eating	Ritual Abrasion
Types of Abrasion:More commonly seen in removable partial dentures	Prosthetic Abrasion
Types of Abrasion:Denture composed of metal and acrylic where metal clasp is placed on the abutment tooth	Prosthetic Abrasion
Types of Abrasion:ADVISE PX: remove dentures to brush/at night	Prosthetic Abrasion
Types of Abrasion:The constant removing will cause abrasion on the abutment tooth by metal clasp	Prosthetic Abrasion
Loss of tooth substances/wearing away of tooth structure	EROSION
Enamel is completely dissolved and dentin demineralized, softened and rendered prone to abrasion and attrition	EROSION
No bacterial invasion	EROSION
Possible reasons:Acidic diet	EROSION
Possible reasons:Drinking softdrinks	EROSION
Possible reasons:Drink coffee	EROSION
Possible reasons:People with GERD	EROSION
Possible reasons:People who throws up a lot	EROSION
Possible reasons:Low salivary flow rate	EROSION
Possible reasons:Bulimic/anorexic	EROSION
Clinical Manifestation:Scooped out depression	EROSION
erosion is more prominent on the	maxillary
types of erosion: Acidic diet	Dietary Erosion
types of erosion: Who eats acidic fruits, consume carbonated drinks/wine	Dietary Erosion
types of erosion: Unknown etiology	Idiopathic erosion
types of erosion: Exposure to chemicals	Occupational erosion
types of erosion: Wine tasters	Occupational erosion
types of erosion: Who works on swimming pools	Occupational erosion
types of erosion: Lead exposure	Occupational erosion
types of erosion: pH lower than 7.35	Acidic saliva
types of erosion: Erosion on oral cavity, hyperacidity disorder, gastritis, bulimia, ulcers, liver schirrosis	Acidic saliva
types of erosion: Lingual surface of the anterior teeth	Persistent vomiting
Pathological loss of tooth substances caused b biochemical loading forces that result in flexure and failure of enamel and dentin at a location away from the loading	ABFRACTION
Seen as Jagged edges	ABFRACTION
Located at the cervical third of the root/ root is involved	ABFRACTION
the ideal relationship of occlusion is	cusp-fossa relationship
ABFRACTION VS EROSION VS ABRASION:Mostly seen in the incisal area of tooth/cusp tips of canine/posterior teeth	Attrition
ABFRACTION VS EROSION VS ABRASION:has a wedge-shaped lesion	Abfraction
ABFRACTION VS EROSION VS ABRASION:Enamel is jagged not smooth but rough	Abfraction
ABFRACTION VS EROSION VS ABRASION:Mostly seen on the contralateral side of mishandedness of the px	Abrasion
ABFRACTION VS EROSION VS ABRASION:Lesion is saucer-shaped	Abrasion
ABFRACTION VS EROSION VS ABRASION:Enamel is smooth	Abrasion
ABFRACTION VS EROSION VS ABRASION:Dentin is highly polished	Abrasion
ABFRACTION VS EROSION VS ABRASION:Those who has coarse diet	Abrasion
ABFRACTION VS EROSION VS ABRASION:Seen in lingual surface of Mx teeth	Erosion
Conservative Treatment of tooth loss is best done through	composite restoration
