Aspects of certain pulp structure modifications in senescence

Being known the fact that the dental pulp, as a particular form of conjunctive tissue organization,
manifests great plasticity by a continuous renovation and permanent adjustment to the enduredthrough-
life injuries, the authors undertook a clinico-hystological study, which tried to perceive its
modalities of reaction to the action of certain aggressive external factors.
Asum of hystomorphological changes which succeeded in spotlighting the way the pulp reacts to the
external injuries such as: decays, coronal restorations, attrition, chronic marginal periodontitis, are
here revealed and analyzed. All these factors lead to slow pulp senescence process.
The modifications vary according to the general status of the organism, individual genetic specific
features, the tooth type and dental pathologic history.
Due to its complex structure, the pulpo-dentinal ensemble has the capacity to deal with the numerous
injuries coming from outside. The dental pulp, as a specific structure of conjunctive tissue,
demonstrates great plasticity, being able to permanently adapt to the action of different aggressive
external factors that influence it throughout life.
The modalities of reaction are various and reflect the defense potential, specific of each individual,
having the task to permanently or temporarily hinder the evolution of morbid processes caused by
external injuries.
Our survey tries to highlight the weight of certain structural changes at pulp level, under the influence
of certain stress-factors.
