JOURNAL FREE ACCESSThe purpose of this study was to examine the reliability and validity of the Japanese parental version of the Dental Subscale of Children's Fear Survey Schedule (CFSS-DS) and to investigate the prevalence of dental fear in young Japanese children.
The following results were obtained.
1) The Japanese parental version of CFSS-DS showed good reliability and validity.
2) The cut-off point of CFSS-DS in young Japanese children was 33.
3) Young Japanese children showed relatively higher dental fear (32.1) than children in other countries. No connection to gender was found (31.6±11.1vs 32.7±11.3p=0.051).
4) Children who have the following factors tend to get high dental fear score: parents with a high dental fear; 5 years old or younger; those who have not consulted a dentist when answering the questionnaires; those who have not experienced local anesthesia and cavity treatment.
5) The CFSS-DS scores for the clinical and general population was approximately the same (32.1±11,2vs 32.0±11.6).View full abstractDownload PDF (2126K) -

JOURNAL FREE ACCESSObjectives: The aim of this study was to examine the hypothesis that the long-term caries preventive program can prevent the occurrence of dental fear. Subjects and methods: The Japanese version of the Dental Subscale of Children's Fear Survey Schedule (CFSS-DS) and the additional items measuring fear of returning to the dentists were given to 107 child patients aged 12-18 years with a mean age of 14.4 ± 1.4 (57 boys,54 girls; mean age at their first visit to the dental clinic was 4.2 ± 3.0years), who had visited Okamoto Pediatric Dental Clinics incet heire arlyc hildhood until the ages of junior-high or high school.
Results: The mean total CFSS-DS score was 22.8±8.0. Fear levels were lower in this group than in the other Japanese group reported in the previouss tudy, and showed dentalf earl evels very close to thoser eported in the Scandinavian countries(23.1 from Sweden,22.1 from Finland). Girlss howed more fear than boys (24,1v s.21.8), but therew as no statisticsailg nificancbee tween them. Drilling, choking, i njectiontsh, e noiseo f dentistd rillinhga, ving somebody put instruments in your mouth, the sight of the dentistd rillincga used the most common fears. The mean total CFSS-DS score corresponded to the fear of returning to the dentist.The childrenw ho were not afraid of dentistrwye re more likely to return to thed entists.
Conclusion: The results of thiss tudy supportedt he hypothesist hatt he long-termc ariesp reventive program may prevent the occurrence of dental fear.View full abstractDownload PDF (1003K) -

JOURNAL FREE ACCESSThe purpose of this study was to investigate the effect of the psychosomatic state on the measurement of the pressure pain threshold (PPT) in the maxillofacial area. To achieve this purpose, first, each of 20 healthy subjects(10males and 10 females; mean age±standard deviation,26.34±2.50years) was given two kinds of the psychological tests (STAI, POMS). Second, the PPT at the bilateral styloid process of the temporal bone of each subject, which is known to be a site having high susceptibility to pressure pain, was measured five times by the same investigator. The measurements were performed by using the pressure algometer that had been improved after referring to the pressure algometers used in past studies. Furthermore, we examined the relationship between each score of indexes in STAI and POMS and the coefficient of variation (CV) in the PPT of each subject. There was a significant positive correlation between each score of the five indexes related to a negative affect in STAI and POMS and CV in the PPT. The present study suggested that the effect of the psychosomatic state might influence the measurement of the PPT in patients with orofacial-pain who have a psychosomatic background. Orofacial pain derives from complex perceptions in the maxillofacial area with sensitivity differing among individuals due to physical, psychological, experiential, and other factors. Effective treatment of orofacial pain therefore requires a reliable understanding of symptoms, particularly an appropriate selection of methods for the assessment of pain.View full abstractDownload PDF (1758K) -

JOURNAL FREE ACCESSPeriodical dental health examinations play a major role in the clinical practice of pediatric dentistry,. To increase the effects of such examinations and the rate of children undergoing them, the evaluation of parent and child awareness of and expectations from the examinations is important. We conducted a survey on the awareness of periodical dental health examinations of children and their parents who visited our department for such examinations during a 2-month period from July 2004.
The subjects consisted of 323 children who gave consent after being given an explanation of the purpose of this study, and the following results were obtained:
1. Concerning what the responders deemed an appropriate in terval between periodical examinations, regarding the most frequent choice was 4 months. Most children considered that hospital visits at the intervals they selected as appropriate were not a burden.
2. Their expectation periodical examinations was most frequently “prevention of caries”, followed in order by “improvement in the alignment of teeth” and “improvement in tooth brushing”.
Regarding whether periodical examinations fulfilled their expectations, mor e than 90% of the children selected “adequately” or “closely”.
3. Concerning how long they felt they should undergo periodical examinations, the most frequent choice was “I should undergo them even after I grow up.”, followed by “until graduation from junior high school.”
It m ay be necessary to increase the understanding of the children and parents, particularly with regard to dentition growth and caries prevention in children after the age of 10 years, when the number of children who undergo periodical dental health examinations decreases.View full abstractDownload PDF (1100K) -

JOURNAL FREE ACCESSIn order to ascertain whether there are any differences in the way of seeking information among infants with different personalities, we tested child subjects using the TS juvenile personality test and divided them into the three groups -(A) the dependent personality group, (B) intermediate group and (C) independent personality group. Their eye movements were then measured with the use of a fullface photograph of a male dentist. The following's what we found:
1. It was suggested that the way of looking at the face of the dentist in the picture by the infants reflected their personality traits.
2. The frequency of eye fixation was highest and the fixation time was longest in group C followed by group B and group A in that order. The fixation points were mostly on the features of the face (the eyes, the nose and the mouth). The number of the fixation points on the facial features was the largest in group C.
3. In every group, the distribution of the saccadic movements centered on the facial features.
4. There were four types of eye scanning. The infants in group C moved their eyes with great regularity.
5. The dependency-type infants looked at the face of the dentist by most of the ordinary children do. The independent-minded infants looked at the face of the dentist the way adults do. The way of casting their eyes by the infants in group A and the ordinary children was not wrong but suggested a developmental stage. We therefore thought that to know why infants look that way is important who understand child development.View full abstractDownload PDF (5289K) -

JOURNAL FREE ACCESSDuring occlusal maturity in children, finger sucking becomes a hindrance regarding the growth and development of the normal upper primary dentition and maxillary bone, and produces malocclusions of the protrusion of the maxillary incisors, anterior open bite, dentitional striction and posterior cross bite.
We therefore created a three-dimensional finite element method model of the maxillary bone from a dry skull in the primary dentition period.
We assumed the degree of the effect of the finger sucking on the palate of the maxillary bone and analized the change in form of the upper primary dentition and maxillary bone.
The following results were obtained:
1. As the part under pressurize with the finger became a part with a deeper palate surface, the overjet became larger and the overbite became shallower for the upper primary incisor.
2. As the part under pressurize with the finger became a part with deeper palate surface, the amount of movement in front and above showed greater increase in the upper primary canine.
3. As the part under pressurize with the finger became a part with deeper palate surface, the amount of movement in lateral showed greater increase in the upper primary first molar.
4. As the part under pressurize with the finger became a part with deeper palate surface, the amount of movement was small.
5. As the part under pressurize with the finger became a part with deeper palate surface, the amount of movement in front and above showed greater increase in the maxillary bone.
We believe that this research can be utilized for the guidance, the diagnosis and the treatment of the finger sucking.View full abstractDownload PDF (5838K) -

JOURNAL FREE ACCESSDespite the recent increase of allergy in child patients, methods to predict allergy and respond to allergic symptoms during dental treatment have not yet been established. The purpose of the current study was twofold; first, to find the prevalence of allergies among children who come to our clinic, and second, to contribute to the guidelines established for safe dental treatment of children with allergies.
The subjects were 1745 child patients who visited our clinic between January 2003 and December 2005 for initial consultation, and who were up 0 to 12 years of age at the time of the first visit. The data were collected from interview sheets and medical records.
The results revealed the following.
(1) 683 patients (39.1%) had some type of allergic disease.
(2) No significant difference was observed regarding major complaints among children with and without a history of allergic diseases.
(3) In terms of types of allergic diseases, atopic dermatitis was the most prevalent, followed by food allergy, asthma, and drug allergy.
(4) More children with a history of allergy were administered with local anesthesia compared to those without allergy.
(5) Children with a history of allergic diseases underwent an intradermal or skin prick test for the local anesthetic agent, and patch test for dental metals, drugs, and materials.
The current study suggested the importance of inquiring into the existence of allergic reactions to drugs and food through sufficient medical interviews. When the results of the interviews suggest the risk of allergic reactions, it is important in child clinical dentistry to administer allergy tests before dental treatment in order to prevent adverse events.View full abstractDownload PDF (1250K) -

JOURNAL FREE ACCESSPrimary school students (aged 9-12 years old) found with white spots (35 chidren involving 103teeth) were monitored. A program on oral health education and tooth brushing instructions using fluoride-containing dentifrice was done. Oral ph otographs were taken using a digital camera with polarized filters. We reviewed the program using photographs taken to evaluate its effect. The photographs were uploaded to the computer and enhanced through RGB separation (removing the green and the red hues, and leaving blue hues). The surface area of white spots was calculated through the use of an image software. The findings are as follows: 1. At the time immediately bef ore beginning the first check up, the average surface area was 9.3 mm. As the program progressed, the surface area of the white spots decreased. There was a significant difference in surface area at the beginning of the first check up and the second check up, and between the beginning of the first check up and the third check up.2.40% teeth showed a decrease at the second check up and at the third check up.22% of the teeth showed a decrease at the second check up but showed an increase at the third check up.25% of the teeth showed an increase at the second check up but showed a decrease at the third check up.8% of the teeth showed an increase and at the second and the third check ups.3. There was no difference between the surface area of the white spot and the right central incisor, the left central incisor, the right lateral incisor, the left lateral incisor at the first, second and third check ups.View full abstractDownload PDF (2961K) -
