dense masses of microorganisms embedded in an
intermicrobial matrix (biofilm).
In sufficient concentration it can disturb the host-parasite

often localized and associated with difficult
eruption, subsides after the teeth emerge into the
oral cavity.
15. 1(ERUPTION GINGIVITIS
The greatest increase in the incidence of gingivitis in
children is often seen in the 6- to 7-year age group
when the permanent teeth begin to erupt.
This inflammation is most commonly associated with
the eruption of the first and second permanent molars,
and the condition can be painful and can develop into
a pericoronitis or a pericoronal abscess.
16. Cause:
This increase in gingivitis apparently occurs because
the gingival margin receives no protection from the
coronal contour of the tooth during the early stage
of active eruption, where Food debris, materia alba,
and bacterial plaque often collect around and
beneath the free tissue, partially cover the crown of
the erupting tooth, and cause the development of
an inflammatory process.
17. treatment
Mild eruption gingivitis requires no treatment
other than improved oral hygiene.
Painful pericoronitis may be helped when the
area is irrigated with a counterirritant, such as
Peroxyl.
Pericoronitis accompanied by swelling and lymph

antibiotic therapy.

27. A) HERPES SIMPLEX VIRUS INFECTION
Herpes virus causes one of the most widespread
viral infections.
The primary infection usually occurs in a child
younger than 6 years of age who has had no
contact with
the type 1 herpes simplex virus (HSV-1) and who
therefore has no neutralizing antibodies.
It is believed that 99% of all primary infections
are of the subclinical type.
The infection may also occur in susceptible
adults who have not had a primary infection
28. Cont…..<<<
the primary infection may be manifested by acute
symptoms (acute herpetic gingivostomatitis). which
runs a course of 10 to 14 days.
The active symptoms of the acute disease can occur in
children with clean mouths and healthy oral tissues.
May be characterized by only one or two mild sores on
the oral mucous membranes, which may be of little
concern to the child or may go unnoticed by the
parents.

1) Is the presence of yellow or white liquid-fi lled vesicles.
2) In a few days the vesicles rupture and form painful ulcers 1
to 3 mm in diameter .
3) covered with a whitish gray membrane and have a
circumscribed area of inflammation.
4) The ulcers may be observed on any area of the mucous
membrane, including buccal mucosa,tongue, lips, hard and
soft palate, and the tonsillar areas.
5) Large ulcerated lesions may occasionally be observed on
the palate or gingival tissues or in the region of the
mucobuccal fold.
6) This distribution makes the differential diagnosis more diffi
cult.

Note:
An additional diagnostic criterion is a fourfold rise
of serum antibodies to HSV-1.

HSV-1.
33. Treatment of acute herpetic gingivostomatitis
in children
the treatments described may be useful, they are only palliative..
A. specifi c antiviral medication as well as provision for the relief
of the acute symptoms .
B. The application of a mild topical anesthetic, such as dyclonine
hydrochloride (0.5%) (Dyclone), before mealtime temporarily
relieves the pain .
C. allows the child to take in soft food..
D. Because fruit juices are usually irritating to the ulcerated area,
ingestion of a vitamin supplement during the course of the
disease is indicated.
E. Bed rest .
F. isolation from other children .
35. Examples of drugs used:
The antiviral medications currently available are acyclovir, famciclovir, and
valacyclovir. These medications inhibit viral replication in cells infected
with the virus. shouldbe administered in five daily doses to equal 1000 mg
per day for 10 days.
mainstay of definitive therapy is regular doses of specifi c systemic
antiviral medication combined with systemic analgesics (acetaminophen
or ibuprofen) during the course of the disease.
Another topical anesthetic, lidocaine (Xylocaine Viscous), can be
prescribed for the child who can hold 1 teaspoon of the anesthetic in the
mouth for 2 to 3 minutes and then expectorate the solution
Schaaf recommends as an alternative to the anesthetic a mixture of equal
parts of diphenhydramine (Benadryl) elixir and Kaopectate. The
diphenhydramine has mild analgesic and antiinfl ammatory
properties,whereas the kaolin-pectin compound coats the lesions.

48. Treatment of RAU
Lesions persist for 4 to 12 days and heal
uneventfully, leaving scars only rarely and only in
cases of unusually large lesions .
Current treatment is focused on:
1) promoting ulcer healing,
2) reducing ulcer duration and patient pain,
3) maintaining the patient’s nutritional intake,
4)and preventing or reducing the frequency of
recurrence of the disease.

106. conclusion
Gingivitis is a reversible disease. Therapy is aimed primarily
at reduction of etiologic factors to reduce or eliminate
inflammation, thereby allowing gingival tissues to heal.
Appropriate supportive periodontal maintenance that
includes personal and professional care is important in
preventing re-initiation of inflammation.
Complete dental care, improved oral hygiene, and
supplementation with vitamin C and other water-soluble
vitamins will greatly improve the gingival condition.
As with all disorders affecting periodontal tissues,
maintaining excellent oral hygiene is the primary key to
successful therapy.

Their primary etiology is bacterial plaque, which can initiate destruction of the gingival tissues and periodontal attachment apparatus.1,2
CHLORHEXIDINE AS A THERAPEUTIC
PLAQUE CONTROL AGENT
Chlorhexidine (CH) is a chlorophenyl biguanide with
broad antimicrobial activity. It has been used commonly
as an antiseptic skin and wound cleanser for presurgical
preparation of the patient and as a handwash and surgical
scrub for health care personnel. It has also been added
as a preservative to ophthalmic products and has been
used internally in very dilute concentrations in the peritoneal
cavity and urinary bladder.
In dentistry, CH has been studied for control of smooth
surface caries, for use as a denture disinfectant, and as a
plaque control agent. Its use in controlling dental plaque
accumulations has received the most attention in dental
research. Mouth rinses containing CH have been popular
as therapeutic agents in several countries for some time,
and in 1986 CH was approved for use in the United States.
Two products under the trade names Peridex (Colgate-
Palmolive Co., New York, NY) and PerioGard (Zila Pharmaceuticals,
Phoenix, Ariz) have received FDA approval as
prescription agents. This mouth rinse contains 0.12% CH
gluconate as the active ingredient.
Widespread use of CH mouth rinses over many years,
especially in Europe, has had an excellent safety record.
Few adverse side effects have been reported with CH
mouth rinses, but their use has been linked to mouth
dryness and burning sensations in some persons due to
the alcohol base. An alcohol-free product is available.
Generalized staining over long-term use and taste alterations
have been reported. Poorly defi ned desquamative
lesions have been observed in others after the mouth
rinse was used. Allergic reactions to CH are rare. If the
rinse is inadvertently swallowed, it has essentially little
systemic effect due to poor absorption in the gastrointestinal
system.
Lِe and Schiِtt reported highly signifi cant inhibition
of plaque formation and the prevention of gingivitis with
use of an aqueous solution of 0.2% CH digluconate as a
mouth rinse twice daily with swishing for 1 minute.31
Yankell and associates have shown that dental stain from
CH mouth rinse can be signifi cantly reduced with regular
use of a tartar-control dentifrice.32
It is important to recognize that the benefi cial use of
CH as a therapeutic mouth rinse should be considered
adjunctive to the practice of sound conventional plaque
control measures as presented in Chapter 11 and elsewhere
in this text. A study by Brecx and colleagues
regarding the effi cacy of Listerine, Meridol, and
chlorhexidine (CH) mouth rinses found CH to be the
most effective to supplement habitual mechanical oral
hygiene.33 They also found a combination of habitual
self-performed and nonsupervised oral hygiene with Listerine
or Meridol is more benefi cial for plaque control
than the use of mechanical oral hygiene alone. Its adjunctive
use would also seem most appropriate for therapy
in cases in which attaining adequate plaque control
is more diffi cult, such as during illness or convalescence
after serious injuries.
The rationale to include use of daily antimicrobial
mouth rinse to the child and adolescent’s oral hygiene regimens when inadequate plaque control exists to control
and prevent periodontal disease and deliver antimicrobial
agents to mucosal sites harboring bacteria throughout
the mouth thereby complementing plaque control is
widely accepted.34,35
Thirty-four allergic children were examined
during two successive spring seasons and the
one intervening fall. Age- and sex-matched controls
were also examined in the fall. Gingival infl ammation
and the presence or absence of plaque were recorded,
and a bleeding/plaque ratio was calculated for each subject.
The results indicated an enhanced gingival infl ammatory
reaction in the allergic children during the
pollen seasons. Although the authors acknowledge that
the signifi cance of gingival reaction during short allergic
seasons is diffi cult to assess, they speculate that patients
with complex allergies who have symptoms for longer
periods may be at higher risk for more signifi cant adverse
periodontal changes.
children 12 years of age and older.
Other remedies for herpes simplex infection also include
the amino acid lysine. The oral therapy is based on
lysine’s antagonistic effect on another amino acid, arginine.
Griffi th and associates conducted an initial study in
which 250 patients were given daily lysine doses of
1000 mg and were told to avoid eating arginine-rich foods,
such as chocolate and nuts.16 The lysine therapy was continued
until the patients had been lesion free for 6 months.
L-Lysine monohydrochloride is available commercially in
capsule form or tablets containing 100 or 312 mg of
L-Lysine (General Nutrition Corp., Pittsburgh, Pa.). The
patients reported that pain disappeared overnight in virtually
every instance. New vesicles failed to appear, and a
majority considered the resolution of the lesions to be
more rapid than in the past. There was also a reduction in
frequency of occurrences. Griffi th and colleagues concluded
that improper food selection may make adequate
lysine intake precarious for some persons.16 Ingestion of
cereals, seeds, nuts, and chocolate would produce a high
arginine/lysine ratio and favor the development of herpetic
lesions. Similar results are obtained when arginine is
added to the medium in the laboratory to induce herpes
proliferation. The avoidance of these foods, coupled with
the selection of foods with adequate lysine, such as dairy
products and yeast, should discourage herpes infection

antiinfl ammatory and antiallergic medication
in the form of a topical paste.
The paste is applied to the ulcer four times
daily, after meals and at bedtime, until the ulcer heals.
Zilactin (Zila Pharmaceuticals, Phoenix, Ariz), a topical
paste with hydroxypropyl cellulose fi lm, has also been
used to adhere to the mucosa and cover the ulcer while
providing pain relief for an extended period of time. Occlusive
topical 2-otylcyanoacrylate adheres for 6 hours.
Aloe vera freeze-dried gel extract adheres and forms an
occlusive protective patch. In severe cases, oral prednisone
has been prescribed.
A therapeutic
trial of antibiotics reduces the acute symptoms in ANUG but not in the viral infection. Acute herpetic gingivostomatitis
is most frequently seen in preschool children,
and its onset is rapid. As stated earlier, ANUG rarely
occurs in the preschool-aged group and develops over a
longer period, usually in a mouth in which irritants and
poor oral hygiene are present. On the other hand, acute
oral infections initially diagnosed as ANUG have frequently
been found later to be an oral manifestation of
one of the xanthomatoses. The early stages of conditions
such as Hand-Schüller-Christian disease and Letterer-
Siwe disease are associated with many of the symptoms
of ANUG.
Although the tissue usually appears pale and
fi rm, the surgical procedure is accompanied by excessive
hemorrhage. Therefore quadrant surgery is usually recommended.
Brown and colleagues have reported a case
in which apically positioned fl ap surgery and CO2 laser
evaporation were used to reduce the gingival tissue.41
Some authors report a positive relationship between the
level of phenytoin in serum and saliva and the severity of
PIGO in some cases.44-46 Other investigators have reported
that no such correlation exists.47,48 It is generally agreed
that a relationship exists between dosage and PIGO when
the level of phenytoin per unit body weight or actual serum
level is considered. Sasaki and Maita reported a signifi
cant correlation between the degree of gingival overgrowth
and a high level of basic fi broblast growth factor
in serum.49 No such correlations were observed for patient
age, daily or total phenytoin dose, duration of therapy, or
serum phenytoin level.
No cure exists and treatment is often symptomatic in nature. Antihistamines, topical
corticosteroids, ascorbic acid (vitamin C) supplements,
topical antibiotics, and alkaline mouthwashes have
been used with limited success and are considered to be
ineffective.

less severe type of gingivitis resulting from vitamin
C deficiency is probably much more common than
most dentists realize.
