1. In oduc ion
The e m “ i al pulp he apy” was o iginally in oduced by
McDonald in 1956, who ad oca ed i s applica ion in p ima y

Wi h he de elopmen o ad anced bioma e ials and a be e

9. Clinical Signi icance in Conse a i e Den is y and
Endodon ics
Vi al pulp he apy (VPT) has eme ged as a co ne s one in
mode n conse a i e den is y and endodon ics. The clinical
philosophy has shi ed om he adi ional “ex i pa e and

A. Biological and Conse a i e Al e na i e o Roo Canal

• VPT p o ides a less in asi e ea men op ion

• By e aining iable pulp issue, i p ese es he

• A oiding unnecessa y RCT is consis en wi h he

B. Reduc ion in T ea men Time and Cos
• VPT p ocedu es a e simple and as e o pe o m

pa icula ly sui able o child en, anxious pa ien s,
and indi iduals wi h limi ed access o ca e.
C. P ese a ion o Too h’s Na u al De ence and Senso y
Func ions
• The den al pulp is no jus a ascula ized issue; i
plays a c i ical ole in he oo h’s de ence.
• Immunological de ence: Pulp issue ac i ely
esponds o bac e ial in asion by mobilizing immune
cells.
• Senso y unc ion: The pulp e ains senso y
inne a ion, enabling pa ien s o de ec he mal,
mechanical, and chemical s imuli, which se e as
ea ly wa ning signals agains u he insul .
• Re aining hese unc ions main ains he oo h as a

D. Signi icance in Paedia ic and Adolescen Pa ien s
• In child en and adolescen s, pulp i ali y is c ucial
o apexogenesis: he con inued g ow h and
ma u a ion o oo s uc u es.
• VPT p ocedu es, such as pa ial o ull pulpo omy,
allow imma u e pe manen ee h wi h pulp

• This is pa icula ly impo an in auma cases, whe e

• By a oiding ea ly oo canal ea men , clinicians
p ese e he na u al biology needed o comple e

E. Success in Ma u e Tee h wi h P ope P o ocols
• Ea lie , VPT was mainly ad oca ed o imma u e
ee h. Wi h he ad en o mode n bioac i e ma e ials
(e.g., MTA, Bioden ine, calcium silica e-based
cemen s), VPT has become a iable op ion e en in
ma u e pe manen ee h.
• Success depends on h ee c i ical ac o s:
a. Accu a e diagnosis: Di e en ia ing e e sible
om i e e sible pulpi is.
b. S ic asep ic echnique: P e en ing mic obial

c. Use o bioac i e ma e ials: Ma e ials ha
p omo e den in b idge o ma ion, pulpal healing,
and a bac e ia- igh seal.
• When hese condi ions a e ul illed, VPT can achie e
long- e m success compa able o RCT, while being
less in asi e.
