Morphology
Meyers conclusions
> The root canal is not round but oval (Ion axis mesiodista
> The root canal does not go straight but it deflects distal
> The outfall is not on the top of the root but
below (distal or distooral
M eye rovy závěry
The form of the outfall is funnel - shaped
ape
> The root canal system has usually more outfalls (ramifications)
> The ramifications are situated mostly in aoic area (first apical mm
> All outfalls are situated in cementům

Less risk of periodontal damage Prevention of overfillin
Prevention of apical transport of infectiou material
Possibility of good bacterial decontamination Possibility of good condensation of the root filling

Normal periradicular appearance Teeth are not tender to percussion
Classification of pulp diseases
Clinical
Irreversible pulpitis
Pain may develop spontaneously or from stimuli
In later stages heat is more significant Response lasts from minutes to hours
When the periodontal ligament is involved, the pain
is localized
A widened periodontal ligament may be seen in later stages
