How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

3. Introduction
• Wound healing is a complex and dynamic process of
restoring cellular structures and tissue layers.
• Favorable environment for wound healing can be, created by
a surgical dressing.
• A surgical dressing allows for uninterrupted healing to occur
and also contributes to the protection of the surgical area and
prevention of wound damage and infection.
4. • Dressing n. protective covering for a wound. (Oxford
Dictionary)
• Periodontal dressing is a surgical dressing used postoperatively
to cover and protect the surface of surgical wound created by
periodontal therapy.
5. • Dr. H . Winnett Orr first advocated (1923) the closed plaster
technique for compound fractures.
• The first surgical dressing was patented by E. P. Lesher in
1953.
• A surgical dressing is also utilized after periodontal surgical
procedures by Zentler in 1918 by using iodoform gauze and
Dr. Ward in 1923, used fast setting cement on the surgical
area.
• Dressings are applied around the necks of the teeth and
adjacent tissue to cover and protect the surgical wound after
periodontal surgery.
6. • Serve as;
1. Bandage over the surgical area holding the flap
2. Protecting newly formed tissue
3. Minimizing postoperative pain infection and hemorrhage
4. Protecting the surgical site from trauma during eating and
drinking
5. Supporting mobile teeth during the healing process.
7. History
• 1918, Zentler-
First reported the use of a periodontal dressing in the form of
iodoform gauze.
• 1923, Ward-
Invented the Wondrpak
• 1942 , Box and Ham-
Use of zinc oxide-eugenol dressing to perform chemical
curettage in treatment of necrotizing ulcerating gingivitis
8. • 1943 , Orban –
Zinc oxide Eugenol + Paraformaldehyde to perform
Gingivectomy by chemosurgery
Dressing caused extensive necrosis of the gingival and bone
and abscess formation.
• 1947 ,Bernier and Kaplan –
For wound healing protection was the primary concern
9. • Ariaudo and Tyrell 1957-
Dressing to position and stabilize apically positioned flap.
• 1962, Blanquie – Fundamental and technique for periodontal
dressing.
Control post operative bleeding
Splint loose teeth
Prevent re-establishment of pocket – desensitize cementum
10. • 1964, Gold-
Splint teeth, as it was cement dressing that set hard.
• 1964 ,Weinreb and Shapiro
Zinc oxide eugenol impregnated cords into periodontal pockets
,but found to be less effective than gingivectomy.
11. • 1969 - Baer et al
Stated that primary purpose of a dressing
1. Patient comfort
2. Protect wound from further injury during healing
3. Hold flap in position.
4. To immobilize a gingival graft by dissipating the pull from
alveolar mucosa and lip
5. They pointed that the dressing should not be used to control
post-operative bleeding, nor to splint teeth .
12. • Antibacterial periodontal dressing
Ramanov 1964 – antibotics in periodontal dressings
encouraged the growth of candida albicans and yeast.
Absoe Jorgerson et al 1974 found that a dressing containing
Chlorhexidine promoted healing
Plyss et al 1975 evaluated the efficacy of CHX when used with
a dressing,
• Light cured periodontal dressing
• Resorbable periodontal dressing
13. Properties of periodontal dressing
• Soft
• Enough plasticity and flexibility
• Set within a reasonable time.
• Sufficient rigidity
• Smooth surface after setting
• Bactericidal properties
14. • Not interfere with healing
• Dimensional stability
• Not induce possible systemic detrimental effects and
allergic reactions
• Acceptable taste
• Economical and easily available
• Good shelf life
15. Rationale of using periodontal dressing
• Protection of the wound area
• Enhancement of patient comfort
• Maintenance of a debris free area
• Control of bleeding: from trauma
• Periodontal dressings also protect newly exposed root surfaces
from temperature changes and protect sutures.
• Protects surgical healing areas from irritants such as hot or
spicy foods.
• Supports mobile teeth during healing
16. Classification or types
(Hall 2003)
Containing zinc oxide and eugenol
Containing zinc oxide without eugenol
Containing neither zinc oxide nor eugenol
17. Eugenol dressing

• Cellulose fibers- Improve setting
• Zinc acetate – Accelerator, better working time
• Asbestos – Binder and filler
19. Liquid
• Eugenol - Anesthetic, antiseptic and obtundent.
• The oil of cloves or the eugenol can be reduced to a very low point
• Alcohol- Germicidal property
• Pine oil- Dissolve resin and rosin
• Pine resin- Adhesive quality
• Peanut oil- Regulates the setting time (Hastens)
• Camphor - Tissue preservative and cuts the bite of the eugenol
20.
21. • Tube 1 base –
87% zinc oxide
13% fixed vegetable or mineral oil
• Tube-2 accelerator –
12% oil of clove or eugenol

22. • These are mixed together on a waxed paper pad using a
wooden tongue depressor or spatula.
• The powder or paste is gradually incorporated into the liquid
until it reaches a dough-like consistency.
• Sets to brittle state like cement
• The dressing may be used immediately or wrapped in
aluminum foil and refrigerated for use for up to 1 week.
23. • A modified of a eugenol dressing was introduced by Kirkland,
called the Kirkland formula.

Substantivity and slow release properties
• In 1989, commercial periodontal dressing had lost its
antimicrobial activity shortly after application.
• Thus, proposed the addition of chlorhexidine to dressing to
improve their properties.
96. Studies
1. Addy and Douglas in 1976; a in vitro and in vivo study,
Concluded that methacrylate gel is a good medium for
carrying chlorhexidine to the wound area and its releasing it
slowly.
2. Plṻss et al. in 1975 incorporated 15 – 20 mg of chlorhexidine
dihydrochloride in Peripac
Concluded that significant reduction in plaque formation and
attributed to direct contact of powder with the tooth.
97. 2. Othman et al found that surgical dressing with antimicrobial
agents are advantageous due to its,
High retention
Slow releasing properties
3. Newman and Addy in 1978,
Used chlorhexdine as mouthwash to swish the oral cavity
following a periodontal flap surgery
Concluded that, less plaque accumulation and less sulcular
bleeding
Patient’s preferred for chlorhexidine rinse than dressing.
98. 5. Zyskind et al. in 1992
Chlorhexidine varnish prior to the application of a periodontal
dressing
Significantly less plaque found on the teeth precoated with the
slow release varnish.
99. Disadvantages

Coe Pak,
Periocare
and
Barricaid
•Coe Pak and periocare absorbed water and acted similar in
manner at 23°C
•Periocare absorbed more water at 37°C
•Barricaid had little effect on its water sorption or solubility
•When immersed in 0.09% KCl solution,
Barricaid showed no effect on conductivity or pH
Coe pak and periocare increase in conductivity slightly and
increase in pH
•Adhesion to a single tooth was noted
Coe Pak
At 1 hour was 7kg, at 24 hours was 6.5kg and at 5 days was
5kg
Periocare
2 kg at 1hour, 8.5 kg at 24 hours and 7.5kg at 7 days
Barricaid
5 kg at 1hour, 3.5 kg at 24 hours and 1.5 at 7days.
Mechanism of adhesion of Barricaid was mechanical
interlocking
Differs from Coe pak and PerioCare
120. • Another study,
Chemomechanical lock between tooth surface and Barricaid
Barricaid gave adhesion value of
43.94 MPa at 1 hour
37.17MPa at 7 days
43.23MPa at 1 hour
19.32MPa at 7 days
Etching
Without etching
121. • Watts and Combe (1979) compared Coe pak, Peripac and
Peripac improved
Concluded that,
None of the dressing exhibited ideal flow properties during
manipulation and adaptation,
None of the dressing exhibited an adequetely well defined set.
123. Effects on wound healing
• Eugenol based dressing had adverse effects and inflammatory
reaction
• Eugenol dressing can cause
Less growth inhibition of permanent cells and primary human
leukocytes than some non-eugenol dressings
Wondr Pak produced greater tissue destruction, more
inflammatory cell infiltration and connective tissue response
Wondr Pak involved wider reaction in adjacent tissues
124. Comparison between eugenol and non
eugenol dressings
• Recently, early irritating effects of dressing may contribute to
postoperative pain and swelling whether or not it contains
eugenol.
• Peripac shown to more irritating than wondrpak
• Tefla may be interposed between tissues to prevent such
harmful effects
125. Studies assessing periodontal dressing
cytoxicity
• Haugen et al (1978) concluded
Wondr pak is most irritating followed by Coe pak and peripac.
• Haugen et al (1979) concluded
Cytotoxicity of Coe-pak increases with time
• Wennberg (1983) concluded that
Peripac is more severe tissue reaction than wondrpak
• Baer and Wertheimer (1961)
Inflammatory reaction is greater when dressing is placed directly on
the bone compared with time when placed on the periosteum
126. Therapeutic effects of antimicrobial
agents in dressing
• Eugenol based dressing were bacteriostatic effect in vitro
• Antimicrobial activity was greatest in Coe-pak while it was
least in peripac
• None of the periodontal dressing showed any mark degree of
antibacterial activity
127. Postoperative pain and dressing
• Jorkjend L (1990) examined the incidence and severity of
postoperative pain after gingivectomy
Comparing Coe pak, wondr pak and Nobetec
Mean pain score after Coe pak was higher than Nobetec
Mean pain score after Coe-pak was higher than after
Wondrpak
No statistically difference found between Wondrpak and
Nobetec
128. Periodontal dressing for all?
• Complete healing can occur without giving a periodontal pack.
• There is no difference in healing between dressed and
nondressed wounds
• Use of dressing accumulates plaque causing inflammation
• Irritates the healing tissues and produces transient bacteremia
during postoperative dressing change
• Causes more pain and swelling but less sensitivity and
difficulty in eating
129. • Healing appears to slightly more rapid in dressed segments.
• Use chlorhexidine mouth rinse instead of dressing was patients
preference while it showed to reduce plaque accumlation
postoperatively and surgical inflammation
• Many patients experienced discomfort when periodontal
dressing was used and preferred mouth rinse
• Some patients exhibited psychological feeling of protection
and well being when a periodontal dressing was put in place
130. • The answer for this question is still controversy and a topic to
debate.
• Choice of periodontal dressing depends on the experience and
judgment of the operator
• Moreover none of the dressing showed ideal properties

Dangerous components
Components Percentage
Luaric acid 25-50%
Elemi resin 1-5%
6- cholorothymol 1-5%
Zinc di acetate <0.5%
134. Conclusion
• No absolute indication for periodontal dressing after
periodontal surgery
• Literature elaborates the benefits of periodontal dressing after
surgery
• We believe that future research to improve the biomaterial
properties may lead to a more universal applicability
• As far now, periodontal dressings for all? maybe yes, may
not!
