Background data about the high dental fear scores of Hungarian 8-15-year-old primary school children

Free associations (coupling) of 139 Hungarian primary school children about their teeth was collected. Dental fear (DAS, DFS) and general anxiety scores were measured. Typical dental events (i.e.: loss of deciduous teeth, simple and traumatising dental treatments, tooth fractures) were coupled by the participants in 41.0% of the cases. Functions and importance of the teeth and oral hygiene were described in 20.1% of the cases. Simple, grotesque, or magical stories and tales about teeth were found in 8.6% of the cases. No answer was given in 30.2% of the cases. Highest dental fear and general anxiety scores were found in the group coupled traumatising dental treatment. Traumatising loss of deciduous teeth was caused by the dentist or by the father of the child, and was associated with higher dental fear and general anxiety comparing to simple loss of deciduous teeth. Higher dental fear and general anxiety scores were found in the group coupled functions and importance of the teeth comparing to the group coupled simple, grotesque, or magical stories and tales, or the group giving no answer.     

Longitudinal study of dental caries development in Dutch children aged 8-12 years

In many Western societies caries experience in children has decreased substantially in areas both with and without organized preventive programs or water fluoridation. In the majority of studies reporting declining caries activity, cross-sectional data of the same age groups are compared. The purpose of the present study is to provide longitudinal data on the progress of dental caries in permanent first molars. 252 caries-active children, initially 8-yr old, were followed up from 1979 to 1983. At all three examinations lower socioeconomic (SES) children had a significantly higher caries experience than children the same age in middle and high SES classes. The D2MF-S counts did not change between age 8 and 10, but increased steeply between 10 and 12 yr of age. The D3MF-S counts, on the other hand, rose steadily in all SES classes. The phenomenon was caused by the progression of enamel lesions to dentinal lesions or fillings, leading to a concomitant decrease in the curves of incipient caries lesions (D2). The rise from age 10 to 12 is attributable to new developing enamel lesions. With regard to predilection sites, at all ages and in every SES class, the highest proportion of both indices was due to lesions in occlusal surfaces, followed by buccal and lingual pits and fissures. The approximal sites were the least affected.     

Model analysis in children at age 8-10 years

Nowadays, we referred to the European standards in model analysis which was important procedure in orthodontic diagnosis and treatment planning. This study was to determine Thai standards according to Korkhaus method from 93 samples (50 males, 43 females) which were selected by purposive random sampling. Their criteria were normal development of occlusion, acceptable facial profile with no any teeth removal and all incisors erupted. There were a significant sex difference in 6 parameters and not differ in the other (alpha = 0.05).     

The bilateral occurrence of dental caries among 12-13 and 15-19 year old school children

The purpose of the study was to determine the bilateral occurrence of dental caries in 12-13 year old and 15-19 year old Saudi school children. There were 673 children (324 boys and 349 girls) in the 12-13 year old group and 734 children (399 boys and 335 girls) in the 15-19 year old group with mean ages of 13.1 (SD 0.7) years and 16.4 (SD 1.2) years, respectively. All children were examined for dental caries using the World Health Organization (WHO) criteria for the diagnosis of dental caries. There were no significant differences between the caries prevalence of right and left sides for most teeth at the significance level of 0.05. Among 12-13 year old children, maxillary first molars (86.5%), mandibular central incisors (86.2%), and mandibular first molars (86.0%) showed very high (p <.01) caries bilaterality. Among the 15-19 year old children, mandibular first molars (91.6%), maxillary first molars (87.9%), and mandibular second molars (79.9%) showed very high (p <.01) caries bilaterality. The conditional probability for bilateral occurrence of caries was highest in first molars followed by second molars and central incisors. The bilateral caries occurrence and conditional probability for bilateral caries occurrence were significantly higher (p <.05) in 15-19 year old children as compared to 12-13 year old children. It was concluded caries bilaterality and the conditional probability for bilateral caries occurrence was high in the study population.     

口服咪达唑仑治疗牙科恐惧症儿童的临床疗效观察

目的对牙科恐惧症儿童实施口服咪达唑仑镇静下的口腔治疗,评估治疗的安全性、有效性及其影响因素。方法选择在口腔科就诊的Frankl量表评分为1的有不良牙科治疗经历的30例患儿为研究对象,共进行了46人次的口服咪达唑仑（0.5～1.0 mg·kg-1）镇静下治疗。治疗时,记录患儿的心率、血氧饱和度、治疗内容及持续时间等。采用Houpt量表评估患儿治疗完成情况,治疗结束24 h后电话回访不良反应。结果46人次治疗中,患儿的生命体征平稳、安全,37人次（80.4％）完成了既定治疗,9人次（19.6％）镇静效果不理想,仅完成部分治疗。烦躁不安是术后最常见的不良反应。3岁以上儿童的治疗成功率高于3岁及以下儿童,性别、剂量和治疗内容与治疗成功率无关。结论口服咪达唑仑治疗牙科恐惧症儿童是一种安全有效的方法,3岁以上儿童的治疗效果较好。     

Prevalence of dental caries and treatment need in 12-15 year old municipal school children of Mumbai

This epidemiological survey attempted to establish the level of dental caries and treatment need among the municipal school children of Mumbai. The prevalence of dental caries was 68.02% which increased with age. The lowest DMFT score was recorded in the 12 year age group while the highest DMFT Score was recorded in 15 year age group. Decayed teeth accounted for the greatest percentage of DMF teeth followed by the missing and filled components in all the age groups. Single surface restorations accounted for the greatest percentage of treatment need followed by two or more surface restorations and extractions.     

Prevalence of caries in Spanish school children and youth of 7, 12 and 15 to 19 years of age

The aim of this study was to assess the dental caries prevalence and severity of the population under 20 years of age in Spain. 1469 young people, aged 7, 12 and 15-19 years, and representing the urban (60%) and rural (40%) population from Spain were evaluated, registering the decayed, extracted or filled teeth for primary and permanent dentition. Average D.M.F.T. for 7, 12 and 15-19-years-old were 1.5, 3.5 and 6.6 respectively. A comparison of the results with those of previous studies showed that the average D.M.F.T. scores have decreased since 1984. We have also observed an increment in the number of caries-free children reaching the 57.9% in the age group of 7 years. But this excitement over the increase in the number of caries-free children must be tempered by the recognition that 35% of these individuals had 70% of the caries. We still need educational, preventive and restorative programs, and focus our efforts in detecting and treating the highly susceptible children.     

Prevalence of dental caries in USAF family members age 3-15

This study was undertaken to determine the caries prevalence and restorative needs of United States Air Force (USAF) family members ages 3-15. Examinations were performed on 1802 USAF children at five bases. Indexes recorded were: Decayed, Missing, Filled Surfaces (DMFS) for permanent teeth; decayed, filled surfaces (dfs) for primary teeth; and a Dental Restorative Treatment Need Index. Results indicate an increase in the dfs and DMFS index with age, with more caries present in young children located overseas. No significant differences between children of officers and enlisted members were found. A higher dfs and DMFS index was found in other racial families as compared to blacks or whites. This study's overall population sample had a higher dfs index but lower DMFS index than the 1986-87 NIDR survey showed.
