The document discusses how people with mental illness are in greater need of oral health care as drug treatments for severe mental disorders can lead to oral dryness, tooth decay, gum disease, dental restorations, and tooth extractions. It also notes that people with severe mental disorders accompanied by avolition can lose motivation to maintain oral hygiene. Finally, it mentions how candies, gums, and drinks used to avoid oral dryness by this population can lead to tooth decay.
3. the use of xylitol to decrease mother-child
transmission of mutans streptococci
Xylitol promotes mineralization
non-fermentable by oral bacteria
decreases counts of mutans streptococci (MS)
as well as the amount of plaque
4. Some MS strains are inhibited by xylitol
MS cells are thought to incorporate xylitol as
xylitol-5-phosphate through the major route
of sugar transport

xylitol gum has been found to be superior
to sorbitol gum in retarding regrowth of

prevention, takashi matsukubo, international

22. Despite being one of the United States‘ 10 greatest public
health achievements of the 20th century (Centers for
Disease Control and Prevention, 2000), community water
fluoridation receives only qualified endorsement from
some systematic reviews of its effectiveness in preventing
dental caries.
Children
→ effective, but reluctant to quantify the effect.
(∵poor quality of many studies)
Adults
→ lack of evidence.
⇒ it hampers the development of health policy.
ex) economic evaluation → no caries-preventive benefit.
23. Before 1990 (now outdated)
→ fluoridated water was effective only
when ingested prior to tooth eruption
Will potential benefits be limited to people
born after implementation of fluoridation, or
might there be additional benefits for people
born before implementation?
24. Effects were compared between the pre-fluoridation
cohort born before 1960 (n=2,270) and the cohort born
between 1960 and 1990 (n=1,509).
Residential history questionnaires determined the
percentage of each person‘s lifetime exposed to
fluoridated water.
Examiners recorded decayed, missing, and filled teeth
(DMF-Teeth) and decayed and filled tooth surfaces (DF-
Surfaces).
Socio-demographic and preventive dental behaviors were
included in multivariable least squares regression models
adjusted for potential confounding.
25. The exposure of interest was proportion of lifetime
exposure to fluoridated drinking water.
The fluoridation database (Australian Research Centre
for Populaiton Oral Health) registers fluoride
concentarations for 99.4% of the Australian
population.
<0.3 ppm F = 0
0.3 ~ 0.7 ppm F = 0.5
≥0.7 ppm F = 1.0
The number of years at each concentration was
multiplied by the concentration.

31. Little is known about the effect of
discontinuation of sealant or fluoride varnish.
The purpose of this study was to compare
sealant with fluoride varnish in the prevention
of occlusal caries in permanent first molars of
children over a nine-year period: 4 yrs for
program evaluation plus 5 yrs of
discontinuation.
32.
33.
34.
35.
36. Results of the active period of the project at both
24 and 48 mos indicated that both treatments
were effective, and that the sealants performed
better than the varnish.
Furthermore, the caries reduction figures up to
48 mos were within the published range of
pooled preventive fractions in available meta-
analyses.
The same conclusions apply to the nine year
results, with a higher loss in preventive effect for
varnish (43.9% at 4 yrs and 27.3% at 9 yrs) vs.
sealant (76.3% at 4 yrs and 65.4% at 9 yrs).
37. The long-term success, measured by
retention and caries prevention, of second-
generation (chemically cured) fissure sealants
has been well-documented.
However, to our knowledge, 9 yrs is the
longest follow-up period to date in a study of
caries reduction with a third-generation
(visible-lightcured) sealant or fluoride varnish,
although comparisons of varnish with other
studies should be interpreted with caution
because of the 5 yrs of discontinuation
47. The Vipeholm studies were published
showing that sugar eaten in the form of large
toffees between meals resulted in severe
damage to the teeth.
However, consumption of sugar even at high
levels was not importantly associated with
increased damage when the sugar was taken
up to four times a day with meals.
It was also concluded that carious lesions
occurred despite avoidance of sugar.
48. Another study showed the importance of the
length of time that is given to the teeth to
remineralise as a determinant of the amount
of caries which develops.
Bowen concluded that it is not necessarily the
frequency of ingestion of sugars that is
related to development of caries, but the
duration that sugars are available to
microorganisms in the mouth.
49. The report mentioned that population
analyses suggest that less than 18kg per
person per year of sucrose intake is linked to
lower rates of dental disease.
50.
51.
52. It is impossible to see a threshold level in
these data.
53.
54. These data do suggest that there is a decline
of caries prevalence in Japan, concomitant
with the increase of the use of fluoride
toothpaste
55.
56. The steep increase in the number of caries
free children occurred when fluoride became
available.
In this period, sugar consumption was
continuously high.
57. Retention of food, food impaction, the
presence of fluoride and the age of dental
plaque are all strongly related to oral hygiene.
58. Bratthal proposed three factors, bacteria, diet
and susceptibility to disease contributing to
the development of caries.
most of the criteria are not easily diagnosed,
cannot be influenced and are not site-specific.
59.
60. Caries prevalence in many EU countries has
declined, while the sugar consumption per
person per year has remained approximately
stable.
The decrease in caries prevalence is primarily
attributed to increased exposure to fluorides
(toothpastes) and improved oral hygiene
techniques
62. Numerous chemical factors, such as pH,
titratable acidity, degree of saturation, kind
of acid, and chelating properties, have been
identified to influence the erosive potential of
acids.
63. However, compared with the chemical factors,
limited information exists about the effects of
the physical or physico-chemical aspects of
the acid on dental erosion.
64. Therefore, the aim of this in vitro study was
to investigate the effects of viscosity changes
of different acidic solutions on dental erosion.
The null hypothesis was that the erosivity of
citric acid and phosphoric acid at different pH
values is not affected by their viscosity.
65. Citric acid (CA) and phosphoric acid (PA)
solutions at pH levels of 2.5, 3.0, and 3.5
were used.
CA solutions at pH 2.5, 3.0, and 3.5 were
obtained by the addition of 2.81, 3.3, and
4.17 g/L (Fluka, Buchs, Switzerland),
respectively, to de-ionized water.
66. PA solutions at the respective pH values were
obtained by the addition of 30.5, 109.3, and
110.3 mL/L, respectively from a 3 mol/L
stock solution (Merck, Darmstadt, Germany)
to de-ionized water.
67. The kinetic viscosities of the acidic solutions
were adjusted to 1.5, 3, 6, 12, and 24
mm2/sec, respectively, by the addition of
hydroxypropyl cellulose (HPC, Grade LM, HPC,
Nippon Soda Company, Tokyo, Japan) at
different concentrations.
68. The respective acidic solutions were dropped
from a reservoir into an inclined (45°) channel
which was made from polyvinyl chloride (8
mm in length) at a flow rate of 1 mL/min,
which directed the acidic solutions over the
surface of an enamel specimen (Fig. 1).
70. Enamel loss by CA and PA at different viscosities.
71. We have shown that the erosive potential of
acids is dependent not only on various
chemical properties, such as pH, but also on
the viscosity of the acidic solution.
72. Since the erosive enamel loss decreased with
increasing viscosity, it can be assumed that
the relative stickiness of the acid solutions
with higher viscosity decreased the ion
exchange and clearance of dissolution
products.
73. At a higher viscosity, this static layer might
be thicker and less undersaturated, so that
enamel erosion decreased.

1. 장애인들은 구강질환에 대해 더 많은 주의가 필요하다.
1) 중증 정신장애인들의 약물치료는
구강건조증, 치아우식, 치주질환, 치아수복, 발치 등을
초래할 수 있으며,
(Kenkre and Spadigam, 2000; Friedlander and Marder, 2002)
2) avolition을 동반한 중증 정신장애인은
구강위생유지 의욕을 상실할 수도 있다.
3) 또한, 구강건조증을 피하기 위해 이용하는 사탕이나 껌, 음료수 등은
치아 우식을 유발할 수 있다.
따라서, 중증 정신장애인들에게는 예방적인 구강건강교육이 특별히
중요하다.

- 하지만 그 효과는 약하고 오래가지 못한다. (Kay and Locker, 1996)
3. 구강건강교육은 개인의 동기를 유발시킬 때 효과가 커질 수 있다.
- 동기면담(MI ; motivation interviewing)은
건강에 대한 태도를 광범위하게 변화시키는 데에 동기를 부여해주며
(Resnicow et al., 2002; Burke et al., 2003, 2004; Hettema et al.,

※ MI(motivation interviewing; 동기면담) 이란?
- 동기면담은 (1) 협동성(Collaboration), (2) 유발성(Evocation), 그리고 (3) 자
율성(Autonomy)의 세 가지기본 정신(Spirit)에 기초하고 있다(Arkowitz, 2009).
- 동기면담에서는
1) 치료자가 환자와 협동적이어야 하며, 권위적인 자세를 피하며,
환자를 치료자와 대등한 위치의 조력자로 대함(협동성).
2) 환자를 직접적으로 설득하고 특정한 방향으로 교육하는 대신에
치료자가 환자의 관심과 생각을 자발적으로 이끌어내는 데 초점맞춤(유발성)
3) 치료자가 환자의 행동에 대해서 즉각적인 선택을 하도록 몰아가지 않으며,
환자의 행동 변화를 유발하는 힘과 동기는
개인 안에 내재한다고 믿는다(자율성)

- plaque index : 1.7 감소 vs 0.8 감소
2. 예상치 못했던 결과는,
MI병행 그룹에서 oral health knowledge가 크게 증가한 것이다.
- MI 병행 그룹은 MI 상담에 의해 동기가 부여됐기 때문에,

introjective에 다소 더 영향을 주었다.
- 이 결과는 선천적 정신질환자의 천성을 반영할 수도 있고,
항정신병약물치료가 동기를 저하시켜 개인들이 내적인 규제를 지켜
가는 것에 지장을 주는 것으로도 생각할 수 있다.

5. 이 실험의 가장 큰 한계는, follow-up 기간의 부족이었다.
- 8주보다 더 긴 시간 동안 추적을 하지 못했음이 유감이다.
6. 또 다른 한계는, 실험의 설계에 있어서
MI 그룹이 구강건강과 관련해서 더 많은 시간을 보냈다는 점이다.
- 이것 자체가 MI 그룹의 교육효과를 더 높였을 수도 있다.

Result: 35 to 60% reductions in caries

decayed/filled buccal and lingual surfaces
(DFS-BL)
100. is possible that frequent lower-dose
exposure to xylitol is beneficial without the
effort of maintaining special programs.
101. In spite of the considerable evidence that xylitol
is an effective caries-preventive and cariostatic
agent, an effective delivery system for xylitol,
especially for children, demanding minimal
adherence yet safe, has not been developed
(5 to 6 grams and 3 exposures)
the xylitol toothpaste studies suggesting that
lower doses and less-frequent exposures might
be effective, but the synergistic effects of xylitol
and fluoride or triclosan cannot be ruled out.
Studies of new vehicles for xylitol, such as a
xylitol-releasing dummy and a pediatric syrup,
have been conducted.
103. This study aimed to appraise clinical
evidence and its risk from bias regarding the
effects of xylitol in comparison with sorbitol
A number of review of clinical trials
comparing xylitol with sorbitol is published
104. Systemic search strategy
: on the basis of their listed title and abstract,
article from the research result were selected
Inclusion criteria
- Tested caries-related primary outcome
- Compared the effects of xylitol with those of
sorbitol
- Included rest and control group
- Used a prospective group
Extraction of data from accepted trials
Statistical analysis
105. Literature search
- Out of nine article, eight article were accepted
Dataset extraction
-chewing 10.5g of gum containing 100% xylitol
five times daily for 5 min per time is associated
with a 3.5-times greater rehardening of soft
brownish discoloured carious lesion(vs sorbitol
gum)
-chewing 10.5g of gum containing 100% xylitol
for 5 min five times deaily for 2 years with 50-
70% fewer caries lesion after 5 year (vs sorbitol
gum)
106. For all other dataset, the information
reported on the number of participant lost to
follow up at the time of assesement was
insufficient to enable sensitivity analysis
It would lead to different conclusion if worst-
case scenario were assumed
107. The chewing of 65% xylitol gum five times per
day was observed to have a preventive effect
against caries after 40 month, but not after
20 months(chewing time was twice) -> time
factor*
Chewing gum containing 589mg sorbitol
over a 2year period was observed to be more
effective in preventing caries than chewing
589mg xylitol gum
108. However, 589mg xylitol gum was observed to
be more preventive than sorbitol after 3 year
The three timed per day intake of 2.67g
xylitol syrup over 10.5 months was no more
effective in preventing caries than a twice
daily intake of 4.0g
-> time, dosage important!
109. Xylitol has been assumed to have specific
anticariogenic properties
The result of this systematic search indicatea
general lack trial covering this topic
The evidence found in support of xylitol over
sorbitol is contradaictory, contains a high risk
for selection and attrition bias and may be
limited

115. It seems reasonable to assume that the use of a
fluoride dentifrice is likely to increase plaque
fluoride concentrations significantly for up to 12
hrs in areas where the water contains fluoride
close to 1.0 ppm, but not in areas with above-
optimum fluoride levels in the drinking water.
Plaque calcium and fluoride concentrations were
positively related under each of the 4 conditions.
Thus, considering that most people do not
completely remove dental plaque after tooth
brushing, the amount of fluoride retained in
plaque can play an important role in caries
control.

117. A barrier to providing sealants is concern
about inadvertently sealing over caries.
The purpose of this meta-analysis is to
examine the effectiveness of dental sealants
in preventing the progression of caries
lesions in the pits and fissures of permanent
teeth.
118. We searched electronic databases for
comparative studies examining caries
progression in sealed permanent teeth.
We used a random-effects model to estimate
percentage reduction in the probability of
caries progression in sealed vs. unsealed
carious teeth.
119. Our outcome measure was the percentage of
caries lesions progressing, where progression
was defined as demineralization or loss of
tooth structure.
To measure effectiveness, we calculated the
relative risk ratio (RR) and its 95% confidence
interval (CI).
R = % lesions progressing (SEALED)
% lesions progressing (NOT SEALED)

124. In conclusion, the evidence supports the
placement of sealants over non-cavitated
caries lesions in the pits and fissures of
permanent teeth in children, adolescents, and
young adults.
Despite variations in study design and
conduct, subgroup and sensitivity analyses
found the effect to be consistent in size and
direction.
131. Major improvements in the oral health status
of the general public have been observed in
many parts of the world as is shown by the
continuous decline in caries prevalence in
children and adolescents.
This is generally ascribed to better oral
hygiene and use of fluoride toothpaste.
132. Dr. Anne Nordblad, STAKES, National
Research and Development Centre for Welfare
and Health (SF) and Dr. Jos van den Heuvel,
Ministry of Health, Welfare and Sport (NL), co-
presidents of the FDI Public Health Section,
chaired the symposium.
Chief dental officers and key representatives
of various fields of dentistry from all over the
world attended the symposium.
133. The percentage of caries-free 5 to 6-year-old
children has increased to more than 50
percent.
The caries prevalence in adolescents (1 2-
year-olds) in Europe decreased from high or
moderate levels in the 1980s to a low level in
the 1990s.
134. This decrease occurred despite the
unchanged diet of the population and has
been attributed to regular mechanical tooth
cleaning using fluoridated toothpaste.
135. Diet plays a role in the development of caries
and erosion but not in periodontal disease.
The association between sugar/sucrose
consumption and caries vanishes when
fluoride toothpaste becomes generally used
at population level.
Thus, regular plaque removal with a fluoride-
containing toothpaste is more effective in
caries control than dietary restrictions
136. The use of fluoride toothpaste has resulted in
a decrease in the prevalence of dental caries
even though no significant change in the
consumption of fermentable carbohydrates
has taken place.
If the teeth were brushed twice a day with a
fluoride containing toothpaste, foods
identified as cariogenic became a risk to the
teeth only when consumed more than seven
times a day.
137. Current and expected future improved oral
hygiene and the use of fluoride containing
toothpaste have made recommendations on
cariogenic foods less necessary at population
level
139. The aim of this study was to estimate the
prevalence of periodontal disease and
treatment needs in a population with the aid
of the CPITN index, to discover cases of
periodontal disease and recommend
treatment. The study was also designed to be
a first step for monitoring the changes in the
disease status over time in the studied
population.
140. The examination included 214 subjects, aged
18 to 60, 84 women (39.25 per cent) and 130
men (60.75 per cent).
The subjects were factory workers in a textile
mill and comprised a representative sample
of workers and staff members from a list of
1500 employees chosen by a simple random
sampling technique.
141. All examinations were conducted under the
same conditions, in a dental chair by a single
examiner to avoid inter-examiner variability.
142. The periodontal examination estimated the
number of healthy sextants (score 0), the
number of sextants with gingival bleeding
(score 1), the number of sextants with
calculus (score 2) and the number of sextants
with periodontal pockets (score 3 [4-5mm] or
4 [>6mm])
143. Of 214 examined subjects, 20 (9.34 per cent)
had no signs of periodontal disease (code 0);
46 (21.49 per cent) presented gingival
bleeding after gentle probing (code 1); 40
(18.69 per cent) had supra- or subgingival
calculus (code 2); 70 (32.71 per cent)
presented pathologic pockets 4-5mm deep
(code 3); 38 (17.76 per cent) had pathologic
pockets 6mm or deeper (code 4).
144. Subjects were classified into different
treatment need categories, according to the
highest score recorded during the
examination, as follows:
0 (no treatment) - subjects with code 0
I (improvement in personal oral hygiene) –
subjects with code 1
II (I + scaling) - subjects with code 2 and
code 3.
III (I+I1 +complex treatment) - subjects with
code 4.
145. The aim of the study was to determine the
prevalence of periodontal disease and the
treatment needs in a population of 214
factory workers in Romania. Of those
examined, 9.34 per cent were in periodontal
health (code 0), 21.49 per cent had gingival
bleeding (code l), 18.69 per cent had supra-
or subgingival calculus (code 2), 32.71 per
cent presented with pathological pockets 4-
5mm deep (code 3) and 17.76 per cent had
pathological pockets 6mm or deeper (code 4).
146. The distribution of these subjects among the
treatment need categories revealed that
30.83 per cent would need improvement in
personal oral hygiene (I), 51.40 per cent from
the subjects would need treatment (I) +
scaling (XI) and 17.76 per cent would need
treatment (I + I I) + complex treatment (I I I).

In a collaboration between the Dutch and Indonesian Dental Associations
a system for oral health care for multiple handicapped children was
initiated in a large care and rehabilitation
institution in Jakarta, Indonesia. Part of the project was to develop a
programme for oral health and hygiene education (OHE), with a specific
plaque control component.
This programme was aimed not only at the handicapped children but also
at their parents and the teaching and (para) medical staff of the institution.
A study to investigate the feasibility, acceptability and effectiveness of the
OHE programme was carried out over a
period of 2% years. The programme was well accepted, effective and of
clinical significance. It is probably one of the first of its kind in a
developing country.
149. II. Introduction

1. children with such handicaps often have different patterns of dental
caries and
missing teeth. Plaque control, gingival and periodontal health are
frequently
poor compared to children of the same age without handicaps.
2. These specific problems have received attention in a number of
industrialised
countries and special oral health care for the handicapped is now
actively
promoted.

2. The programme
1) OHE material was designed and adjusted to the parents‘ education
level. The parents were grouped according to the educational level of the
mother and each group consisted of not more than seven persons.
OHE lectures were also given to the teachers and to the therapists
working at the institution, to increase general knowledge, create support
for the programme
and better understanding of the physical conditions and the special care
needed for the handicapped children.
2) At the first visit children were taken to the dental clinic, they were
accompanied by the persons who were responsible for the oral cleaning.
At the dental clinic children were seated on the dental chair or remained
seated in their wheelchair. Instruments used for the plaque scoring
consisted of an operating light, mouth
mirror, explorer, disclosing solution, cotton buds and a special piece of

2. The programme
3) Tooth brushing instruction according to the Bass technique was
demonstrated.
4) a fluoride gel was applied with a cotton bud on the teeth surfaces and
left in place for 20-30 minutes before the patients were allowed to rinse.
5) The children returned a week after the first visit together with the
persons who were responsible for the oral hygiene. A review and
evaluation of oral cleaning
was then conducted and if the oral hygiene was not adequate, training
and teaching of toothbrushing was repeated.

3. Examination and Calibration
1) The plaque scores were taken and noted according to Albertson30.
- Scores:
0 = no plaque present;
1 = plaque covering 1/3 of the surface;
2 = plaque covering more than 1/3,
but less than 2/3 of the exposed tooth surface.
3 = plaque covering more than 2/3 of the exposed tooth Surface;
2) The plaque score was taken of each child every 4-6 months leading to
8 scores taken over a period of 32 months.

1. Inquiries revealed the following reasons for non-participation:
the parents of 27 children preferred their own family dentist and/or they
knew already about oral health education
2. The results of the oral health education and plaque control programme,
as expressed in the mean plaque scores (between 0 and 18) are
presented in Table 3.

1. It can be concluded that specially designed oral health education and
plaque control programmes can be developed gradually, gaining more
support of the staff of the institute and the parents. The participation rate
at the start of the project was relatively low. However, this was not
unexpected as it was a completely new activity at YPAC and in fact, in
Indonesia as a country.
2. The decrease in mean plaque scores in the present study over 32
months seems to be somewhat smaller than the results obtained by
Brown over a three year period% and by Nicolaci and Tessini over an 18
months period26, but greater than reported by Shaw and Shaw over two
years2‘. However, as in the present study all showed a gradual decrease in
plaque scores over time. Comparisons remain difficult because of
differences in study groups, OHE methods and plaque recording.

3. One of the reasons for the continuing decrease in plaque scores
obtained in this study might have been the tailored approach to all parties
concerned. Oral
hygiene and the specific procedures were not left to the individual
handicapped person, but taken as a compulsory part of their general care
carried out by mother,
nurse or maid or under very close supervision at home, and repeatedly re-
enforced by professional personnel at the YPAC institute.
4. In conclusion, the specially designed oral health and hygiene
programme for handicapped children involving staff and therapists of the
institute, and parents and carers, is effective and of clinical significance. It
is probably one of the first of its kind in a developing country, and was
successfully developed by an initiative for collaboration between the
Indonesian and the Dutch Dental Associations.
