DISEASES OF PULP AND PERIAPICAL TISSUE
DISEASES OF THE DENTAL PULP Inflammation of the pulp or pulpitis
1. Reversible pulpitis
- inflammation of the pulp or hyperemia
- First stage when the pulp gets inflamed
- Pulp is vital and inflamed BUT
- Possesses reparative capabilities,
capable or returning back to health
- Pathognomonic sign: Provoked
pain/symptoms (meaning if you don’t
have the stimuli it will not be painful)
Causes of Pulp Disease - Acute mabilis parang nangilo (biglaang
- The causes of pulp disease are Physical, sakit ), (biglaang nag inflame)
Chemical and Bacterial. - Ex: you drink cold water pagkainom mo
1. Physical sumakit or nangilo then after you drink
a. Mechanical (trauma, or when you are nawala kaagad.

b. Thermal (difference in temperature) (hyperemia) with prolonged vasodilation
c. Electrical (Galvanic current from (dilated blood vessels)

2. Chemical (phosphoric acid with an echant -Dilation of pulp blood vessels.

3. Bacterial (by products of bacteria) -Presence of immunologically competent
Why is it that the tooth only feels pain chronic inflammatory cells.

- Because it is enclose to in a hard tissue, POLYMORPONUCLEAR CELL ( very
whenever there is inflammation there is fist cells that go to an inflamed area)
expansion or there is increase pressure -Other cells are PLASMA and
due to increase in blood flow, there LYMPHOCYTES
would be increase in intrapulpal pressure
so the dentin and enamel cannot expand.
- The tooth has no capability to expand
that why there is pressure that the tooth
only feels pain. Even if you apply heat or
cold, only pain is being perceive by the
tooth.
Inflammation of the pulp or pulpitis
1. Reversible pulpitis
2. Irreversible pulpitis Treatment:
a. Acute - cause is caries – RESTORATION
b. Chronic - good prognosis if restored properly
B.1 Chronic Hyperplastic *do not neglect reversible pulpitis because
B.2 Internal resorption pwede syang maging irreversible pulpitis
