[Application of the Ricketts analysis to children in the primary dentition. Fourth Report: development of lateral cephalogram analysis system and consideration of facial pattern].

A lateral cephalogram analysis system has been developed allowing an extended application of the Ricketts analysis to primary dentition. Using this system, we first examined the growth of facial patterns from the BA-NA ratio profilograms. As samples, we used records of children with normal occlusions stored at Nihon University School of Dentistry Department of Pedodontics. We then used the Fuzzy theory to change Vert's formula and obtained facial types. Lastly, we obtained compositional ratios of facial types within each age group. The results were as follows: 1) Facial patterns tended to show three divisions according to three age groups; from 3 to 5-year olds, from 6 to 7-year olds and from 8 to 10-year olds. 2) The Vert's values of the BA-NA ratio profilograms in each age group based on the data of 9-year olds tended to decrease as age increased. The change was mostly restricted to the range of Mesiofacial type. 3) As for the compositional ratio of facial types in each age group, a nearly normal distribution was observed mainly with the Mesiofacial type. 4) From the lateral cephalogram analysis system which has been developed and the profilograms of the average values for each age group which have been obtained by this system, we obtained the standard values for future evaluation of facial patterns of children with malocclusions.

[A survey inquiry of clinical examination for 12 years at dental hospital attached to School of Dentistry at Matsudo].

Of the total of 1,371,122 out patients who received the clinical examination in the department of Clinical Pathology. Dental Hospital, Nihon University School of Dentistry at Mastudo for 12 years during April 1, 1977 to March 31, 1989, their clinical examination data were gathered and evaluated. The following results were obtained. 1) The average number of patients who received examination was 1,582.2 per year. 2) The ratio of male to female of the examined patients was 1 to 1.04 respectively. 3) The largest number of patients examined was in their age of 40's in both sexes. 4) Among the various clinical departments, oral surgery department most frequently requested clinical examination followed by head and neck surgery, pedodontics conservative dentistry and anesthesiology departments. 5) Among 7 major clinical examination including general, hematological, biochemical, serological, bacteriological, physiological, and pathological examinations, biochemical evaluation was most frequently requested. In average, 30.5 different examinations were performed per patient. 6) Recently, among pathological and serological examinations, the request of HBs antigen and syphilis examinations were increased.

[An investigation of X-ray examinations classified according to cases of dental diseases at Fukuoka Dental College Hospital].

This paper reports the results of an investigation on the types and frequencies of X-ray examinations given to patients with various types of their dental diseases from their first visit to the hospital to the end of treatment. The subjects were 337 patients (not including orthodontic patients and in-patients) randomly sampled out of all those who visited the Fukuoka Dental College Hospital in 1986. Out of these 337, the number of those who were given X-ray examinations was 284. 1. The Cases of dental diseases for which X-ray examinations were given were classified into the following seven: diseases caused by dental caries, trauma, inflammation, diseases of temporomandibular joint, diseases of salivary gland and other diseases, and other examinations. Out of these X-ray examinations, those given to the patients of diseases caused by dental caries and marginal periodontitis amounted to the 60% of the total X-ray examinations. 2. On the average, 3.3 radiographs were taken per patient. 3. In the examination of luxation, a case of trauma, 7.8 radiographs were taken per patient, the largest number of all diseases on this report. In the examination of marginal periodontitis, a case of inflammation, 5.4 dental radiographs and 0.5 panoramic radiograph were taken per patient. It is necessary to make the most of panoramic examination effective for this disease to decrease radiation exposure. 4. The diseases that have more difficulty of diagnosis and more necessity of observing the prognosis had a greater tendency to depend on X-ray examinations. 5. The percentage of the patients who did not receive X-ray examination was 15.7%. Out of these patients, the patients in pedodontics accounted for 34.5%.

[Statistical studies on numerical anomalies of teeth in children using orthopantomograms--congenital hypodontia].

Statistical studies on numerical anomalies of teeth using orthopanthomograms had been attempted. In this paper, congenital hypodontia had been researched using 4009 orthopanthomograms of pedodontic patients. The tested were following; Male: Age 2-5 1036, 6-11 905, 12-22 Total 1963 Female: Age 2-5 1032, 6-11 985, 12-29 Total 2046 respectively. Many interesting results have been acquired, i.e. A. Congenital Hypodontia of Deciduous Teeth total 62 cases (78 teeth) 1 tooth defect--46 cases 2 teeth defect--16 cases B. Congenital Hypodontia of Permanent Teeth total 314 cases (566 teeth) 1 tooth defect--150 cases 2 teeth defect--115 cases 3 teeth defect--23 cases 4 teeth defect--18 cases 5 teeth defect--6 cases 6 teeth defect--0 case 7 teeth defect--1 case 8 teeth defect--1 case C.

In addition, the data have no significant difference in right and left, male and female. And for many reasons, we criticize the established theory (?) that congenital hypodontia is a systemic degeneration in human evolution. So we propose a following, simple and not incompatible concept--eventually congenital hypodontia except hereditary cases appear in many chances when development of dental germs (I2, P2, M3) is later than the surroundings and the space for it is remarkably deficient.

[Dentist's understanding on dental anesthesiology--on the basis of a questionnaire on post-graduation study].

We set out a questionnaire for 400 participants of the seminar, to investigate the thoughts of dental practitioners and dentists on duty with regard to the post-graduation study and training in particular, to dental anesthesiology. The results obtained were as follows. 1. Almost all of the dental practitioners felt necessary to receive the post-graduation study and training to brush up their techniques. 2. The dental practitioners felt defective in actual techniques prepared by post-graduation trainings now under way, and they desired a particular training in an actual technique specific to an emergency therapy. 3. Seminars for re-education they desired to attend were those related to anesthesia in majority, followed by prosthetics, maintenance and periodontosis, orthodontics, and surgery, implantodontics, and pedodontics. 4. Major curriculums of anesthesiology they desired to receive were systemic management, resuscitation, how to apply the first-aid medicine, and treatment for shock states. The number of those participants who desired to receive these curriculums was help or above of all members, followed by those in dental psychosomatic disease, treatment for senile patients and acupuncture anesthesia. 5. It was unexpected that those who had been aware of the concept of authorized dental anesthesiologist were confined to 54% of the participants. This led us to consider that clinical dentist should be re-educated regarding the system for authorized anesthesiologist. 6. Major participants answered nothing with regard to the advocated curriculums we questioned, so that it was postulated that none felt unsatisfactory of the advocated curriculums at present.

[Treated case with horizontally impacted mandibular first molar caused by submerged primary molar].

A case is here presented in which mandibular first molar was horizontally impacted under the submerged primary molar. The patient was an 8 year-old-boy referred from a general dentist through the Department of Pedodontics in this hospital, whose chief complaint was a horizontally impacted mandibular first molar. Skeletally, diagnosis revealed an Angle Class II Division 2 malocclusion. The impacted first molar was uprighted with a lingual arch and a utility arch following the extraction of the submerged primary molar. The submerged primary molar was probably ankylosed causing a locking of the first molar which rotated as the root formed. The result of rotation during forming twisted the roots of the first molar, which will make root canal treatment difficult if the pulp is infected in the future. It may concluded that dental arches should be carefully observed even in the deciduous dentition.

[Statistical studies on numerical anomalies of teeth in children using orthopantomograms. Congenital coexistence of hyperdontia and hypodontia].

Statistical studies on numerical anomalies using orthopanthomograms had been attempted. In this paper, congenital coexistence of hyperdontia and hypodontia in individuals had been researched using 4009 orthopanthomograms of pedodontic patients. The tested were following; Male: Age 2-5 1036, 6-11 905, 12-22 Total 1963. Female: Age 2-5 1032, 6-11 985, 12-29 Total 2046. respectively. And 11 (male: 7, female: 4) coexistence cases were found. They were combinations of a hyperdontia (1 tooth: 5, 2 teeth: 2, 3 teeth: 1, 4 teeth: 2, 7 teeth 1) and a hyperdontia (1 tooth or 2 teeth).

Paediatric dentistry as a specialty in Sweden. Responsibilities, changes during the past decade and future perspectives.

The results from a questionnaire to all specialist clinics (n = 38) in Sweden concerning their activities during 1989 show that 1% of all Swedish children between 0 and 19 years of age were treated at specialist clinics in pedodontics. The decrease in caries prevalence during the last decade has not resulted in a decrease in the number of referrals. The major reason for referral was high caries activity in combination with behaviour management problems. Seventy per cent of the specialists' working-hours are spent in clinical treatment and about 11% in educational activities. In the future the need for specialist treatment will continue to change to other areas than those of today, such as medically compromised and socially handicapped children.

[Dental treatment for children under general anesthesia].

A clinico-statistical survey was carried out on dental treatment for children under general anesthesia who visited the clinic of Pedodontic Department, Matsumoto Dental College Hospital during the period of 1986 to 1989. The number of cases subjected in this survey was 108 (57 boys 51 girls), aged from one year and 5 months to 8 years and 9 months. All of these patients were admitted to the hospital for 3 days and were treated under general anesthesia, using GOE in 107 cases (in 80 cases by nasal intubation, in 27 cases by oral intubation). One case was administrated by intravenous anesthesia with Ketamine. The results were as follows: 1. The patient ages of the patients ranged from one year 5 months to 8 years 9 months. 2. Thirteen percent of the patients were handicapped. Fifty three percent of the patients had to visit hospitals in remote areas. 3. The number of restored teeth per patient was 15 on the average. The teeth were treated with composite resin filling in 8.5 teeth, composite resin crown in 2.6 teeth, metal crown 3.6 teeth and other material in 0.8 (extraction). 4. Pulpal treatment was carried out on 42 percent of the subjected teeth. 5. The average anesthesia administration time was 3 hours and 28 minutes. No serious trouble was observed although minor complications were seen post-operatively such as high fever or vomiting in some cases.

[Supernumerary teeth in the deciduous dentition].

The Authors presented sovrannumeraries (S) teeth in primary dentition, and the pedodontic, surgical and orthodontic problems. Semeiotics signs, and X Ray suggested, are described. All the types of S. teeth are showed: supplementaries, conoides, tuberculates and infundibuliformes. For every type characteristics, problems and surgical timing are described. Tuberculates and infundibuliformes teeth are the most dangerous for the permanent teeth interrupted: eruption delay, dilacerations, impactions, fusion, follicles, diseases, are reported. The direction of the growth of S. teeth must be analyzed. If the direction is external the timing of surgery is very important. Finally the Authors emphasized the role of cooperation of pedodontist, with oral surgeon and orthodontist for to obtain good results.

[Health problems of the stomatognathic system in the Polish population receiving stomatological health care. 2. Raising environment and education].

On the basis of examination of 4872 preschool children and children from elementary schools and university students a usually unfavourable health condition of the stomatognathic system was found, but this condition was relatively least bad in elementary school children. A much better condition of the stomatognathic system was demonstrated in children attending preschool clinic than pedodontic clinics. The obtained results show that the aim of oral hygiene outlined by the WHO by the year 2000 can be achieved only by a part of children and adolescents.

[Study on thermal pulp testing of immature permanent teeth].

The duration of reaction to cool stimulation was investigated in 185 normal maxillary right and left central and lateral incisors from 55 pediatric patients aged from 6 to 15 years, who were brought to the Department of Pedodontics of Nippon Dental University Hospital, and from 9 students aged from 19 to 20 years in the School of Dental Technology and Hygiene affiliated with Nippon Dental University by using Dichloro-Difluoro-Methane coolants [PULPER (G-C Dental Industrial Corp.) and PULPOFLUORANE (Septodont Co.)] in order to determine the efficacy of thermal pulp testing for mature and immature permanent teeth. The results obtained are as follows: 1) The mean duration of reaction to cool stimulation according to the type of teeth was 0.93 sec for the maxillary left lateral incisors, 0.91 sec for the maxillary left central incisors, 0.88 sec for the maxillary right central incisors and 0.95 sec for the maxillary right lateral incisors, showing no statistically significant difference in the duration between the tooth types. 2) The duration of reaction to cool stimulation according to age was shortened with aging except for the 6-year-old patients. 3) The patients were divided into those 10 years old or younger and those older than 10 years because the tooth roots of the maxillary anterior teeth are developed at 10 years of age. The mean duration of reaction to cool stimulation was 1.02 sec in the group with immature permanent teeth, which consisted of patients aged 10 years or younger, while it was 0.82 sec in the group with mature permanent teeth, which consisted of patients aged 11 years or older.(ABSTRACT TRUNCATED AT 250 WORDS)

[Investigation into the actual condition of outpatients. I. The environmental and oral health status prior to and at the first visit. Comparison of the results between present study and last investigation].

The purpose of this paper was to investigate the actual status of environmental and oral health conditions prior to and at the first visit of the outpatients who visited the pedodontics clinic of Tohoku University Dental Hospital during the period from April 1981 to May 1986, and to compare them with the results of the same kinds of investigation carried out 10 years ago. The subjects were 895 children, with questionnaires being filled out by their mothers. The following results were obtained. 1) As to methods of nursing, breast feedings have increased, while bottle feedings have decreased. The weaning period of almost all of the children was a period between 3 and 6 months of age, as the same as found during the last investigation. 2) The number of children who had eating and drinking habits at bedtime decreased relatively compared with the last investigation. 3) The majority of the children ate between meals twice a day regularly, eating fruits, senbeis (rice crackers), potato chips, and drinking milk frequently. These tendencies in the present study were almost the same as the results of the last investigation. 4) The number of children brushing more than twice a day has been increased compared with the last investigation, and most of them have been brushing their teeth after breakfast and before going to bed. 5) About 87% of the mothers of the patients thought that dental caries are an illness, but 8.9% of them did not. 6) As to caries prevention at home, the majority of the mothers were concerned about tooth-brushing habits and eating habits between meals. In conclusion, this study indicated that concern about oral health of mothers has increased in recent years.

[Investigation into the actual condition of outpatients. II. Correlation between the daily habits of eating and toothbrushing and the prevalence of dental caries incidence].

The purpose of this paper was to investigate the correlation between the daily habits of eating and tooth-brushing and the prevalence of dental caries in the outpatients who visited the Pedodontics Clinic of the Tohoku University Dental Hospital during the period from April 1981 to March 1986. The subjects were 877 individuals with questionnaires which the mothers had filled out. The following findings were obtained. 1) The dft index for children aged 1 year to 6 years in the present investigation was lower than that of the same age group investigated 10 years ago. 2) The dft indicies according to each feeding group were 8.86 in the bottle feeding group, 7.51 in the breast feeding group and 6.77 in the mixed feeding group. 3) The group in which the weaning period was late showed a significantly high dft index. 4) The dft index of the group taking beverages containing sugar before going to bed was significantly higher than that of the group without doing this. 5) The group of patients aged 2 years to 5 years who had between-meal snacks more frequently showed a high dft index. 6) The irregularity of the between-meal eating times caused a high tendency toward caries occurrence. 7) The group having between-meal snacks while playing showed a significantly higher dft index than that of the group having it at a table and not playing. 8) No relation was observed between the frequency of tooth brushing and the dft index.

[Clinical evaluation of low viscosity composite resin].

This study was to evaluate clinically low viscosity composite resin. The subjects of the present study were 121 children aged 2 to 10 years who visited the Pedodontic clinic of Tohoku University Dental Hospital and 53 children aged 2 to 8 years who visited the clinic of the general practitioners in Sendai. A total of 451 cavities (343 at the clinic of the University Hospital, 108 at the clinic of the general practitioners) were treated with Clearfil SC-II (Kuraray). The observation period varied from 1 month to 33 months after treatment. The restorations were examined with regard to spacing or stepped abrasion in the marginal region of the fillings, fracture, loss, attrition and discoloration of the fillings, and recurrent caries and/or pulpal involvement of the treated teeth. The following findings were obtained. 1) The restoration cases treated at the clinic of the University Hospital were evaluated as clinically acceptable in 254 cases (74.1%), while those treated at the clinic of the general practitioners in 76 cases (70.4%). 2) Of the 343 restorations treated at the clinic of the University Hospital, 73 (21.3%) exhibited poor restorative conditions, while of the 108 restorations treated at the clinic of the general practitioners, 15 (13.9%) showed such conditions. 3) The incidences of poor restorative conditions for anterior restorations were 39.7% and 8.3% respectively at the clinics of the University Hospital and general practitioners. 4) The incidences of poor restorative conditions for posterior restoration were 16.9% and 17.7% respectively at the clinics of the University Hospital and general practitioners. 5) Among the poor restorative conditions, the spacing or stepped abrasion and recurrent caries in the marginal region of the restorations occurred more frequently. 6) The incidences of spacing or stepped abrasion and recurrent caries in the marginal region of the restorations increased in the cases of class II and III cavities.
