A curriculum for primary care dentistry.

This paper is a discussion of curricular planning with respect to primary care dentistry. It is meant to be anticipatory, although the proposals contained are transitional and evolutionary rather than abrupt. It is intended to be suggestive rather than authoritarian and exemplary rather than definitive. Many of the recommendations and suggestions are already operative in dental education, albeit in limited or experimental form. An overview of both the content and the process of a primary care dental curriculum is presented, and several specific recommendations for curricular change are submitted. Among the more salient recommendations are (1) changing the admissions process to attract to dentistry those most qualified for primary care; (2) moving the basic sciences into the predental curriculum during the initial phase in the development of primary care dentistry; (3) substantially increasing the amount of behavioral science in the dental curriculum; (4) placing curricular emphasis initially on diagnosis and expanding the competence of the primary care dentist in endodontics, periodontics, pedodontics, orthodontics, and prevention; (5) initiating student group practice as the vehicle for patient care; (6) including intradisciplinary and interdisciplinary training as integral components of primary care curricula; (7) extending the curriculum; (8) establishing general practice or primary care residencies either as an intracurricular experience or as a postdoctoral requirement; (9) reorganizing dental school clinics and clinical training to reflect primary care curricular goals; (10) making more rational use of existing auxiliaries, the eventual goal being auxiliaries who perform most of the routine functions; and (11) ultimately integrating dentistry into medicine so that the future primary care practitioner receives both medical and dental training. It is obvious that the extent to which any of these recommendations will be implemented depends on a great deal more than what happens within a dental school. There are many putative countervailing forces which can make implementation difficult; on the other side of the ledger, these same forces might be propitious. As an illustration, the staggering financial constraints imposed on the dental schools can cause us to throw up our hands in despair or can impel us to look carefully at what we are doing, ask why we are doing it, and by building on what is sound and discarding the antiquated and irrelevant, reassemble our curricula to meet public need better than we have been doing...

[Kalipsol-based balanced intravenous anesthesia in pediatric outpatient dental practice].

Basing on clinical studies of anesthesia in 568 children, central hemodynamic studies, analysis of the blood acid-base balance and gases, glycemia level, and assessment of the psychoneurologic status, the authors validate the usefulness of calypsol-based anesthesia in practical outpatient pedodontics. Such anesthesia did not influence the stability of central hemodynamics parameters, nor did it change the acid-base balance and blood sugar level; it provided an adequate protection of the patient from surgical stress with the adaptation mechanisms remaining intact. The child may leave the clinic 2.5-3 h after the intervention and a test for adequate adaptation to the environment. Calypsol-based balanced anesthesia improves outpatient care of the children, introduction of this method into practice will bring about a good economic effect.

[Prevalence of talon cusp in patients aged 7-18].

Talon cusp is an uncommon malformation. The aetiology is unknown although it is thought to be the combination of genetic and environmental factors. The purpose of the study was to examine the prevalence of talon cusps in children aged 7-18. 600 model casts were examined in the Pedodontic and Orthodontic Department of the Semmelweis University. Classification of talon cusps used was based on the degree of formation and extension by Hattab et al [6]. 12 talon cusps were found in the group of type 1, two were found in group of type 2 and one in type 3. The prevalence of talon cusps was 2.5%, mostly on the upper permanent lateral incisors. In four cases it was bilateral. The prevalence of talon cusps was more frequent in males compared to females. The early recognition of the anomaly is important from the therapeutic point of view (placement of sealant, periodic reduction of the cusp).

A survey of disinfection of irreversible hydrocolloid and silicone impressions in European Union dental schools: epidemiologic study.

PURPOSE: The objective of this cross-sectional study was to describe corresponding procedures for irreversible hydrocolloid and silicone impressions taught and used in European Union dental schools. MATERIALS AND METHODS: A self-administered questionnaire requesting information about rinsing and disinfection methods was sent to each of the 373 heads of prosthodontic, pedodontic, and orthodontic departments in the 131 European Union dental schools. Response rate was 94%. Statistical analysis included chi-square or Fisher exact tests, and ANOVA or Kruskall-Wallis tests. RESULTS: Of the responding departments, 92% systematically rinsed their impressions. Fifteen percent of the departments, mostly orthodontics, never disinfected irreversible hydrocolloid impressions, and 11% never disinfected silicone impressions. The immersion method was used by 65% for irreversible hydrocolloid impressions (73% for silicone), with a disinfection time of 10.3 +/- 6.3 minutes (11.8 +/- 7.4 for silicone). The disinfected impressions were not rinsed by 16% for irreversible hydrocolloid and 14% for silicone. Most departments used brand-name products. CONCLUSION: The same disinfection procedure for both irreversible hydrocolloid and silicone impressions was used by 78% of departments. There was great diversity, however, between departments in the procedure used for each impression material.

[The investigation and analysis of children with dental fear].

PURPOSE: The purpose of this study was to investigate and analyze the clinical behavior and factors causing dental fear (DF) in children of different ages to provide some valuable information for preventing and reducing the incidence of DF in clinical practice. METHODS: 571 cases of children patients receiving treatment in the pedodontics were evaluated and analyzed according to the evaluation standards of DF. RESULTS: The results suggested that the incidence of DF differed in different age groups. The ratio was higher in younger groups while it was lower in elder groups. The ratio also varied with living conditions,education level of mothers,past experience of dental treatment and other children's response at the clinic. CONCLUSION: The DF caused by various factors can be reduced by the combined effort of children, parents and the medical practitioners.

Comparative evaluation of clinical efficacy of gallium and amalgam alloys in primary molars.

The present study was conducted to compare the clinical efficacy (marginal integrity and bulk fracture) of two alloys--Galloy (gallium based) and Aristaloy (amalgam based) in primary molars. 90 primary molars with initial caries formation were selected. 45 were restored with Galloy and 45 with Aristaloy in Class I and II preparations. They were evaluated at two-month intervals for 6 months. The results showed that Galloy performed at par with Aristaloy with regards to marginal integrity and bulk fracture. Hence Galloy can be considered as an interesting substitute in Pedodontic practice.

[A decade of experience in craniofacial surgery].

Our craniofacial surgery team includes experts from the following fields: plastic surgery, neurosurgery, ophthalmology, genetics, neurology, orthodontics, pedodontics, facial rehabilitation, psychiatry, social work, anesthesiology and intensive care. Craniofacial surgery became to a large extent pediatric surgery, following evidence that careful, early surgery does not impair growth and that development following surgery is almost normal. The malformations that were repaired included those of the Crouzon and Apert syndromes, requiring frontal remodelling and advancement of the middle third of the facial skeleton; hypertelorism in which orbits were moved to the midline; large craniofacial clefts in which the hemiface from either side was moved to the midline; and different types of craniostenosis in which frontal advancement and remodelling with reconstruction of the vault was performed. The series consisted of 78 patients who presented between 1979-1989. 3 illustrative cases are described.

Shear bond strength of one 4th and two 7th generation bonding agents when used by operators with different bonding experience.

PURPOSE: To test the hypothesis that simpler-to-use dentin adhesives (7th-generation adhesives) perform better when used by inexperienced operators than do the more complex 4th-generation adhesives. MATERIALS AND METHODS: Six operators with no previous experience regarding dental adhesives, three residents in pediatric dentistry, and three experienced dentists used one 4th-generation dentin adhesive (MA) and two 7th-generation adhesives (MB and MC). With each adhesive, each operator performed 6 bondings to enamel and 6 bondings to dentin. After 24 h of storage in water at 37 degrees C, the shear bond strength was determined. RESULTS: The pooled results showed that the bond strength to dentin was higher (p < 0.05) than that to enamel (dentin mean value = 14.0 MPa, SD = 9.1 MPa; enamel mean value = 11.9 MPa, SD = 7.1 MPa), and that adhesive MA performed better (p < 0.05) than adhesives MB and MC (inexperienced operators = 16.2 +/- 10.9 MPa; residents in pedodontics = 12.0 +/- 6.8 MPa, and experienced operators = 10.7 +/- 4.8 MPa). Of the two 7th-generation adhesives, one performed better on enamel than on dentin, while the other 7th-generation adhesive performed better on dentin than on enamel. Regarding operators, there were large individual variations. The inexperienced bonders performed as well as the residents (p > 0.05), while the experienced operators performed best (p < 0.05). CONCLUSION: In general, the tested 4th-generation adhesive performed better than the 7th-generation adhesives. Even inexperienced operators performed better with the more difficult-to-use 4th-generation adhesives than with the 7th-generation adhesives. Dentin adhesion was stronger than enamel adhesion.

Rubinstein Taybi syndrome.

Rubinstein Taybi syndrome or Broad Thumb and Hallux syndrome is a genetic multisystem disorder characterized by facial dysmorphism, growth retardation and mental deficiency. A ten-year-old boy who had come to the Department of Pedodontics, Ragas Dental College, Chennai, with the chief complaint of unaesthetic appearance with extra teeth revealed delay in the developmental milestones. The patient appeared to be hyperactive and mentally retarded. Extra oral features revealed distinctive facial appearance with a broad fore head, hypertelorism, broad nasal bridge and beaked nose. Intra oral features observed were talons cusps in the upper central and lateral incisors, mesiodens, carious teeth and plaque accumulation. Since the patient was hyper active and mentally retarded, the dental treatment was done under GA. The treatment plan and dental management of this patient are discussed in this case report.

[Studies on the changes of adaptation with children in the dental setting. The relationship between the changes of adaptation and various psychological tests].

The purpose of this study was to discover the changes in the adaptation of children to the Dental setting, and to discover the relationship between the adaptation, and the personality of the child, the personality of the mother, as well as the relationship between the mother and child. The subjects were 60 two to six year old children and their mothers who visited at the Department of Pedodontics, School of Dentistry, Showa University. The results were as follows: 1) The changes of adaptation were classified in groups of four classes. Four groups: Continuous Adaptability (45.0%) Acquired Adaptability (18.3%) Continuous Inadaptability (16.7%) Extreme Inadaptability (20.0%) 2) The inadaptability groups (Continuous Inadaptability and Extreme Inadaptability) of the two to three year old children did not correlate to the change of adaptation and personality of the child, and the relationship between the mother and child. 3) The extreme inadaptability group with the four year old children showed a connection with the change of adaptation and the various Psychological Tests. Concerning personality, the children showed elements of "dependence" "retrogression" and "maladaptation to school (kindergarten)". Concerning the mother child relationship, there were elements of "anxiety" "dotage" "follow blindly" "disagreement". 4) Nobody showed extreme inadaptability in the group of five to six year old children. Continuous Inadaptability group with the five to six year old children showed scarcely any problems. 5) The Personality of mother did not correlate to the change of adaptation of children in the dental setting.

[A clinical evaluation of an improved copper amalgam].

The author presents the results of physicochemical trials and preliminary clinical assessment of modified copper amalgam, carried out to master the optimal method for its preparation. The optimal conditions for the preparation of a filling from modified copper amalgam consist in mixing 0.42 +/- 0.02 g of the alloy powder and 0.3 g of mercury within 25-35 sec. Clinical trials have demonstrated the advantages of this modification vs. the filling manufactured in this country previously, this recommending it for practical pedodontics.

[Approximal caries in children].

A longitudinal radiological study in children (N = 549) who participated in a comprehensive maintenance program (they were treated in the clinic of the Department of Pedodontics of the Academic Centre for Dentistry Amsterdam) suggests that changes in the approximal surfaces of deciduous molars may differ from the changes in the approximal surfaces of permanent (pre)molars. Regression and initiation possibly occur more frequently in the deciduous teeth than in permanent teeth.

[A histopathological study on hypoplasia of the enamel].

The research on the development and injury of the hard tissue of teeth was studied by the pedodontic departments of nine dental schools. We participated in this research and studied histopathologically hypoplasia of the enamel in particular. There were seven selected teeth which had obvious hypoplasia of the enamel. We conducted observations with the naked eye, replica, general microscopy, polarized light microscopy, fluorescence microscopy, and microradiography. Moreover we studied to classify these cases into three types, that is to say, the injury factors of whole body, locality, and unknown origin. The results obtained were as follows. 1) As for the injury factors for the whole body, the bottom of the enamel defects were located corresponding to the incremental line of Retzius in the case of enamel hypoplasia of the deciduous teeth. Also enamel hypoplasia was located near the dentino-enamel junction corresponding to the surface of hypoplasia. 2) As for the injury factors with respect to locality, the bottom of enamel defects were located corresponding to the incremental line of Retzius. The dentino-enamel junction was irregular and discontinuous, still more a part of that area, and the dentin protruded or was exposed. 3) As for the injury factors of unknown origin, hypoplasia was located from the surface of the enamel but it did not spread. Also the hypoplasia of the enamel did not correspond to the incremental line of Retzius. 4) Five cases had fluorescence lines in enamel or dentin.

[Five years evaluation of nitrous oxide sedation in dentistry].

Nitrous oxide-oxygen sedation in dental treatment has been used to a limited extent at the dental schools in Oslo and Bergen since the middle of the 1970-ies. Anesthetists were responsible for the sedation until 1983. Since then two dentists at the pedodontic departments, one in Oslo and one in Bergen, have been licensed for the use of nitrous oxide. The aim of this study was to evaluate dental treatment performed under nitrous oxide sedation in Bergen during the period 1983-88. Data from 435 treatment sessions in 151 patients were analysed. Most of the patients were children anxious of dental treatment. The acceptance was excellent in 315 (72.4%) and fair in 106 (24.4%) treatment sessions. The concentration of nitrous oxide being administered during the dental treatment was most frequently between 40% and 60%. The acceptance and cooperation from the patients were better with low concentrations of nitrous oxide than at higher levels. The side effects/complications were few and mild (4.1%). This study shows that nitrous oxide-oxygen sedation in dental treatment is excellent and safe for many patients that cannot be treated conventionally.

Relation of ectodermal dysplasia and hypodontia.

Ectodermal dysplasia and hypodontia were diagnosed in three families who referred to Gazi University Pedodontic Department in 1989. From the view point of dentistry, it is intended to point out the genetic transitive character of ectodermal dysplasia and its possible relation with hypodontia. Also; some approaches to satisfy the patients in social and psychological aspects besides replacing the functional and cosmetic demands were carried out.

A cross-sectional study on the skeletal development of the hand and wrist from preadolescence to early adulthood among Chinese in Taiwan.

In order to study the skeletal development of the hand-wrist among Chinese in Taiwan, a total of 1,679 hand-wrist radiographs were collected from the files in the Division of Orthodontics, School of Dentistry, National Taiwan University and the Orthodontic Clinic of the National Taiwan University Hospital. The ages of the subjects ranged from 6.3 years to 22.7 years. The nine commonly used ossification events, PP2 = ,MP3 = ,S, MP3cap, DP3u, MP3u, Riu, Rau and Rcu, were used in this study. It was found that the sequence of the nine skeletal maturation stages did not differ between males and females and was generally in agreement with similar studies among other ethnic groups. A statistically significant difference did exist between the males and females in the mean ages of onset of the skeletal maturation stages. All of the skeletal stages were more advanced in the females than in the males. The mean ages of the nine skeletal maturation stages obtained in this study could be used as a reference for daily pedodontic and orthodontic practice as well as for related studies. Although there was no intention of making a statistical comparison of the data for the Chinese with those of other ethnic groups, some diagrammatic illustrations for comparison were made.

[Effect of maxillary protracting bow appliance on reversed occlusion in deciduous dentition].

Previously we investigated the frequency of malocclusion in children who visited the Pedodontic Clinic of Kyushu University and the types of appliances to treat the reversed occlusion in deciduous dentition. The purpose of this study was to evaluate the effects of the maxillary protracting bow appliance to the reversed occlusion in deciduous dentition. Patients at the Hellman's dental age IIA and without molar cross-bite were selected. Eleven patients (6 males and 5 females) were treated with the maxillary protracting bow appliance, and 9 patients (5 males and 4 females) were treated with the chin cap. The controls were 15 patients (5 males and 10 females) without, distal step type of terminal plane, caries and malocclusion. For the sake of evaluation, the study models and lateral cephalograms were analyzed, which were taken before and after the correction of reversed occlusion. The results were as follows: 1. The effects of maxillary protracting bow appliance were the maxillary forward movement associated with counter-clockwise rotation of the nasal floor and the mandibular backward movement associated with clockwise rotation. 2. The maxillary protracting caused the labial inclination of the primary incisors in the maxilla, but the dental arch length was reduced by the mesial movement of the primary second molars in the maxilla. 3. From the results of multiple regression analysis in the maxillary protracting group, it was indicated that the increase of the overjet was attributable to the change of angles of SN-GN, SNB, SNA and GZN.
