Question 13

Matelski et al , Effects of alternative palatal root access technique on fracture resistance of root canal treated maxillary fourth premolar teeth in dogs, Frontier 2020

What was the mean force applied on all teeth before fracture

Answer 13

813 N

Question 14

Matelski et al , Effects of alternative palatal root access technique on fracture resistance of root canal treated maxillary fourth premolar teeth in dogs, Frontier 2020
What was the conclusion of this study concerning different access sites and sizes and tooth fracture?

Answer 14

This study do not support the hypothesis that an increased access size will result in decreased fracture resistance of endodontically treated maxillary fourth premolar teeth. No treatment group was found to have a statistically different mean fracture resistance or resulting fracture pattern.

Answer 15

CCF 65%
CRF 17%
Root fractures 12.5

Answer 16

49.% % are dentialveolar fractures and
enamel dentin pulp fractures ( CCF)

How does an increase in the crown height diameter ratio affect the fracture resistance of canine teeth in the study>

Answer 19

o For each standard deviation increase in the crown to heigh diameter ratio (0.04) there leads to a decrease of 14N in fracture resistance
