JVD 2007 deck Flashcards
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Does endodontic treatment change the strength, toughness, or load-to-fracture ratio? Does it make dentin more brittle via desiccation?
No to both! Level of strength an endodontically tx tooth is the same.
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser,What is one of the leading causes of endodontic failure?
Coronal leakage of restoration
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Teeth treated with good endodontic obturation and good restoration had what % success rate? Good endodontic restoration and poor restoration?
91.4%; 44.1% (restoration more important!)
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, What type of crown has the best strength?
Full gold metal crown; better than non-endodontically treated tooth too
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Human study: 1y after obturation with cast restorations what was the success rate (tooth present vs absent)?
91.7%
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Human study: success rate for maxillary premolars % without coronal coverage and with? (1273 teeth) For maxillary molar teeth?
premolars: without coronal coverage 56%, with 93.9%. molars: w/o coronal coverage 50%, with 97.8%
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Endodontically treated teeth without crowns were what times a greater rate of being lost than crowned teeth?
6 times
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, 1,462,936 endodontically treated teeth: 97% present >8y later. Of the failed teeth (3%) what % had no full crown coverage?
85%
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, What is better: full coronal coverage or cusp coverage?
Full coronal coverage
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Was composite or amalgam better for restorations?
composite
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, What is the average bite force for a dog? When do these forces increase the most?
20-937N (1 pound of force=4.4N); increase when all four canines are used in a pulling motion
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, What is the maximum pulling force in a dog?
480-1126N
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Human forces? Weakest/strongest over which teeth?
244-1246N. Weakest 146N incisors; Strongest 306N molars
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, Which teeth in humans are most susceptible to irreversible damage when no crown is placed?
Posterior teeth; w/o crowns at 1, 2, and 5y post treatment were 96%, 88% and 36% successful, respectively
According to: “Crown restoration of Endodontically Treated Tooth: Lit Review.” Coffman, Visser, 41 crowns on canine teeth in 18 working dogs reported success rate of _____ for crown restoration. Overall success rate was ___?9/81 teeth received a metal crown. Of these how many were successful?
88%; 69% overall success rate; 8/9 successful with metal crowns
According to “Validation of a New Dental Plaque Quantification Method in Dogs” What are the benefits of GCPI over logan boyce
allows for more reliable quantification, awake animals, measures plaque at gingival margin, where relevance is
documented (rather than whole tooth surface)
According to “Validation of a New Dental Plaque Quantification Method in Dogs” How is the GCPI calculated?
measure gingival margin on maxillary 3-9 and mandibular 4, 6, 7, 8 from mid point mesial to midpoint distal using a special
gingival contour probe (rounded to nearest mm). Measure legth of this contour covered by plaque. Total both of these numbers and represent score as a percentage of gingival contour covered with plaque.
According to “Tooth Preparation and Impression for Full Metal Crown Restoration” What type of margin is recommended for crowns in animals?
Chamfer Margin
According to “Tooth Preparation and Impression for Full Metal Crown Restoration”What depth should the initial cut at the margin of the tooth be?
0.5-1 mm
According to “Tooth Preparation and Impression for Full Metal Crown Restoration”What teeth are most commonly prepared for crown placement?
Canine teeth and maxillary 4th Premolar
According to “Tooth Preparation and Impression for Full Metal Crown Restoration”What should be avoided in your preparation?
Unsupported Enamel, undercuts, pyramid shaped canine teeth
, uneven defects in the margin
According to “Osseous Surgery to Augment Treatment of Chronic Periodontitis of Canine Teeth in a Cat” What common signs of PD dz are unique to felines?
buccal bone expansion, alveolar osteitis, canine tooth
extrusion/ supereruption
According to “Osseous Surgery to Augment Treatment of Chronic Periodontitis of Canine Teeth in a Cat” Why was osseous resective surgery employed?
Most reliable/predictable pocket reduction technique
According to “Osseous Surgery to Augment Treatment of Chronic Periodontitis of Canine Teeth in a Cat” What is the most important determinant of periodontal disease?
Genetics
