Restorative treatment

2. What Drugs can be applied
restorative and endodontic
treatment ?
• Pulp Capping
• Pulp necrosis generating
• Endodontic retorative materials contains
aiding drugs
• Haemostatic agent
• Antiseptics
• Topical local aneasthesic agents

3. Pulp Capping
• Pulp dent: Premixed Calcium Hydroxide
Paste For Vital Pulp Therapy and Root
Canal Therapy Bactericidal –
Bacteriostatic (High pH destroyes baterial
cell wall) - Radiopaque Calcium Hydroxide

4. Pulp Capping
• stimulates consistent dentin bridge
formation.
• The new dentin bridge re-encloses the
pulp in its own natural protective chamber
and is visible clinically after approximately
2-3 months.

5. Endodontic retorative materials
contains aiding drugs
• Endodontic retorative materials contains
aiding drugs
• Active Points Chlorhexidine ® from
Roeko) that contains Chlohexidine in
order to desinfect route canal.

6. Endodontic retorative materials
contains aiding drugs
• Tempacanal ®
• Antimicrobial intracanal dressing
between visits in order to desinfect
canal .
• Used for
• large periapical lesions and cysts
• Transverse root fracture
• Avulsed teeth

7. Different Calcium Hydroxide
Preperations

8. Pulp necrosis
• (Caustinerf Arsenical ® from
Septodont) that contains Arscenica
Hydrochloride in addition to Lidocaine
and Ephedrine Hydrochloride used to
generate pulb necrosis.

9. Haemostatic agents
• Haemostatic agent used to stop
hemorrage from the inflammated pulp,
and injured gengiva they are four types:
• Hemostaic dressings
• Absorbable Gelatin
• Astringents and styptics
• Vasoconstrictors

10. Haemostatic dressings
• The simpliste way of bleeding control is
to apply sterile gauze with moderate
pressure.
• Collagen dressing may be applied
• In more severe casses (bony bleeding)
Absorbable Gelatin Sponge may be
used

11. Absorbable Gelatin Sponge
• Applied on the operated tissues,
controls oozing and seal up the
bleeding tissues immediately. This
prevents blood loss from the deeper
wounds
Example : Surgispon ®
• absorbed biologically within 4-6 weeks
• Not used in Restorative and
Endodontics practice

12. Thrombin
• Can be apply locally, especially with
patent having oral anti-coagulant drugs
• thrombin can regulate the growth, cell
cycle progression, and functional
reorganization of the pulp tissue during
pulp healing and inflammatory
processes (Mei-Chi Chang,1999)

13. Astringents and styptics
• An astringent (also spelled
adstringent) substance is a chemical
compound that tends to shrink or
constrict body tissues
• Styptics (also spelled stiptics) are a
specific type of antihemorrhagic agent
that work by contracting tissue to seal
injured blood vessels
• Zinc, iron, and aluminum salts are the
best Astringents and styptics
substances used in dentistry

14. Vasoconstrictors
• Applied locally and for a very short
time.
• Can be injected, but it is better to avoid
to do this
• adrenalin dipped gauze are available in
the market

15. Examples
• Astrigedent X ® from Ultradent
• Dental TD Zett ® from J.Morita
• Quick Stat FS ® from Vista

16. Astrigedent X ® from Ultradent
• Astrigedent X is an aqueous 12.7% iron
solution containing equivalent ferric
sulfate and ferric subsulfate for difficult-
to-stop, problem bleeding
• Less acidic than competitive iron
subsulfate solutions

17. Dental TD Zett ® from J.Morita
• It is a fast-acting intraoral topical
hemostatic agent.
• It combines aluminum chloride, which has
an astringent action, with Cetylpyridinium
chloride and also lidocaine.
• Indications - For hemostasis in the
following cases:
1) Subgingival abutment tooth or cavity
preparation
2) Gingival retraction during Gingivoplasty

18. Quick Stat FS from Vista
• 15.5% Ferric Sulfate Haemostatic Gel
• Provides effective tissue management
when completing impressions,
restorations, crown & amp; bridge, and
Pedodontic pulp treatment
• Doesn`t flow onto surrounding tissue

19. Oral Rinses
Rinses are generally classified by the
U.S. Food and Drug Administration
(FDA) as either :
• cosmetic
• therapeutic
• a combination of the two.

20. Cosmetic rinses
• Cosmetic rinses are commercial over-the-
counter (OTC) products that help remove
oral debris before or after brushing,
temporarily suppress bad breath, diminish
bacteria in the mouth and refresh the
mouth with a pleasant taste.

21. Therapeutic rinses
• Antiplaque/antigingivitis rinses containing
an active bacteria- fighting ingredient such
as quaternary ammonium compounds,
boric and benzoic acid phenolic
compounds.
• Anticavity fluoride rinses.
• Topical antibiotic rinses
• Enzyme rinses
• Artificial saliva rinses
• Rinses that control calculus formation

22. Natural/Herbal Oral Rinses
• Natural oral rinses do not contain alcohol,
harsh chemicals, dyes or preservatives.
They often contain herbs with beneficial
properties and alternative ingredients
• For instance, Xylitol, a natural sweetener
derived from the fibrous parts of plants,
helps reduce the risk of tooth decay and
promotes oral health. Recently several
chewing gums have entered the
marketplace that contain Xylitol and are
promoted as reducing decay.

23. Examples :
• Phenol products: Listerine ®
• Chlorhexidine products: Peridex ®
• Herbal Sanguinaria products: Viadent ®
• Therapeutic Anticavity Fluoride Rinses :
Oral-B ® Anticavity Rinse
• Cosmetic Breath Freshening Mouth
Rinses: Signal ®

24. Side effects
• ulcers
• sodium retention
• stains
• soreness
• numbness
• changes in taste
• painful mucosal erosions.

25. Symptoms of an oral rinse
overdose include:
When swallowing especially by children
1. Breathing problems, such as deep
breathing, rapid shallow breathing,
slowed breathing or breathing stoppage
2. Gastrointestinal problems, such as
abdominal pain, diarrhea, nausea and
vomiting
3. Nervous system problems, such as coma,
dizziness or drowsiness

26. Symptoms of an oral rinse
overdose include:
4. Bluish skin, particularly lips and
fingernails
5. Collapse
6. Convulsions
7. Decreased blood pressure (hypotension)
8. Less-frequent urination
9. Excessive sweating and thirstiness
10. Trouble walking normally
11. Slurred speech

onset.

flavored solution

32. Pharmaethyl ®
• Topical freezing agent with natural mint
flavor.
• Pharmaethyl is used for local applications
