what conditions/pathologies are involved in endo disease?
trauma tooth surface loss caries fractured teeth pulpal pathology periapical pathology root resorption
what is a lateral canal?
a branch of the root canal
how does caries progress to pulpal necrosis?
breakdown of enamel surface progression to dentine bacterial invasion into pulp reversible changes necrosis of pulp tissue
what are the features of apical periodontitis?
chronic poly-microbial infection
stimulation of host response
ct destcruction
what are the clinical objective of RCT?
removing canal contents
eliminating infection
what is chemomechanical disinfection?
mechanical and chemical remove bacterial burden
what is obturation?
filling of space to render inert
prevent bacteria coming in and multiplication of existing
what is an endo-restorative interface?
to provide an environment that allows healing of periradicular tissues so that the tooth is retained as a functional unit
