ABSTRACT
Objective:To explore the effect sense of security and self-control on parent-child cohesion and externalizing problem behaviors in primary and middle school students.Methods:A total of 1 402 primary and middle school students were investigated with the problem behavior frequency scale(PBFS), family adaptability and cohesion scale(FACES-CV), security questionnaire(SQ) and brief self-control scale(BSCS). SPSS 25.0 and PROCESS v2.16 were used for statistical analysis, and common method deviation test, Pearson correlation analysis and intermediary effect analysis were used in the analysis.Results:Parent-child cohesion of primary and middle school students was positively correlated with security and self-control ( r=0.279, 0.303, both P<0.01), which was negatively correlated with externalizing problem behaviors ( r=-0.154, P<0.01). Security was positively correlated with self-control ( r=0.567, P<0.01). Security, self-control and externalizing problem behaviors were negatively correlated ( r=-0.147, -0.250, both P<0.01). The security and self-control of primary and middle school students played a partial mediating role between parent-child cohesion and externalizing problem behaviors.The mediating effect consisted of two paths: one was parent-child cohesion-self-control-externalizing problem behaviors, the other was parent-child cohesion-security-self-control-externalizing problem behaviors. The effect values of these two paths accounted for 20.52% and 20.26% of the total effect respectively. Conclusion:Parent-child cohesion not only directly affects the externalizing problem behaviors of primary and middle school students, but also indirectly affects the externalizing problem behavior through the independent mediating effect of self-control and the chain mediation of security-self-control.
ABSTRACT
Objective@#To compare the long-term dental treatment effects, oral health habits and oral-health-related qualities of life of children treated under general anesthesia (GA) and passive restraint (PR), respectively. @*Methods@#Twenty seven 2 to 4-year-old children treated under GA and thirty four children treated under PR were recruited in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology. Up to 2 years after the treatment, a follow up assessment was conducted. The data of general information, dental plaque level and the unplanned treatments were recorded and analyzed. The questionnaire of oral health habits and early childhood oral health impact scale (ECOHIS) for each child was also completed and analyzed. The survival rate and median survival time of the deciduous teeth were calculated. Multivariate analysis was performed by using Cox proportional hazard model. @*Results@#Twenty-five children under GA and 32 under PR were finally included, with a total of 1 098 deciduous teeth. The postoperative dental plaque indicesin both GA and PR groups had significantly improved than that of before the treatments (P=0.019, P<0.001). The oral health habits had also improved, and the improvement in PR group was more obvious than that in GA group. Totally 128 teeth (27.0%) appeared unplanned treatments in GA group and 232 teeth (37.2%) in PR group during the follow-ups. The new caries and recurrent caries in PR group were significantly more than that in GA group (P<0.001, P=0.012). No significant differences were found between the two groups in restoration failure, secondary caries and endodontic diseases (P=0.129, P=0.822, P=0.642). However, the time of occurrence of endodontic disease and secondary caries in GA group were significantly longer than that in PR group (P<0.01, P<0.001). The median survival time of teeth in GA group was 1 018 days comparing to 944 days in PR group. The difference was statistically significant (P<0.05). The survival rate was associated with such factors as decayed-missing-filled tooth (dmft), anterior or posterior teeth, feeding frequency, brushing habits and behavior management techniques. @*Conclusions@#The long-term dental treatment effects of children treated under GA was significantly better than that of PR group. Continuous reinforcement of proper dietary and oral hygiene habits might help in maintaining the long-term treatment effect.
ABSTRACT
Objective:It has been demonstrated that anesthetics exposure may lead to neurocognitive impairment in developing brain of animal models.However,for the limitation that the animal models can-not fully mimic the dose and duration in clinical settings especially for dental general anesthesia,the cli-nical significance of anesthetics exposure on developing central nervous system remains undetermined. Therefore,we conducted the current study in order to observe the fluctuation of intelligence quotient (IQ)after the administration of dental general anesthesia comparing to that before surgery.We conducted the current study in order to observe the fluctuation of intelligence quotient (IQ)after the administration of dental general anesthesia compared with that before surgery.Methods:Thirty two patients,ASA Ⅰ, who were exposed to dental general anesthesia in Department of Pediatric Dentistry Peking University School and Hospital of Stomatology,aged 4 to 6.5 years,were enrolled in this prospective study.Patients with severe learning difficulties or communication disorders were excluded.Written and informed consent was obtained from each patients’family which was fully explained of the purpose and method of study. Their intelligence quotients were evaluated with the Chinese Wechsler young children scale of intelligence (Urban version)before and 2 weeks after dental anesthesia.They were treated by experienced pediatric dentists and the sevoflurane,propofol and nitrous oxide were used for general anesthesia by anesthetist. Articaine hydrochloride and epinephrine tartrate injections were used for their pulp treatment or extrac-tion.The examiners and scorers for IQ had technical training in the test administration.All the patients were tested by the same examiner and with standardized guide language.Each subtest was scored accor-ding to the tool review.Verbal IQ and performance IQ consisted of relevant 5 subtests and full scale IQ. Statistical analyses were performed by SPSS 18.0.All the scores of subtests and 3 types of IQ were ex-pressed as x-±s.Paired two-tailed t test was applied and P cant.Results:The results of intelligent assessment from 28 subjects were collected.The anesthetic time was (163.4 ±32.6)min and the number of treated teeth was 12.1 ±2.3,mean age (4.60 ±0.41 ) years;age range=4.04 to 5.44 years.Among the patients,there were 13 girls and 15 boys.There was no significant difference in gender distribution.The postoperative full IQ (128.46 ±10.85 )was higher than that before surgery (124.64 ±11.46,P=0.017).We found that the elevation of performance IQ, to a large extent,contributed to this change in full IQ (P=0.007).Correspondingly,there was no sta-tistical difference in the verbal IQ,which was 119.68 ±11.74 to 120.21 ±15.61 (P=0.854).Con-clusion:Dental general anesthesia has no negative effect on the intelligence of preschool children,who were treated under general anesthesia by sevoflurane,propofol and nitrous oxide for 2 to 4 hours.The full IQ and performance IQ were slightly enhanced after treatment which can be explained by the memory effect.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the children's oral health habits and oral-health-related quality of life following treatment under dental general anesthesia (DGA) and passive restraint (PR).</p><p><b>METHODS</b>In the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology, twenty eight 2 to 4-year-old patients treated under DGA and thirty five treated under PR were collected in this non-randomized controlled trial. The general information including age and decayed, missed and filled teeth(dmft), dental plaque index was recorded preoperatively. Two questionnaires, questionnaire of oral health habits and early childhood oral health impact scale (ECOHIS) were completed by parents before and 6 months after treatment (including restoration, root canal treatment, stainless steel crown, tooth extraction, etc.). Six months after treatment, dental plaque index and restoration were reexamined.</p><p><b>RESULTS</b>The patients were significantly elder in DGA group [(3.1 ± 0.6) years old, P < 0.05], and the mean dmft was significantly higher (13.1 ± 4.1, P < 0.001) in DGA group. The postoperative dietary habits and brushing habits significantly improved in PR group, but not in the DGA group. However, according to the results of ECOHIS, the occurrence of pain, the impacts of patients on daily life, psychology and family due to the oral diseases significantly decreased in DGA group (P < 0.05), while in PR group, only the occurrence of pain reduced (P < 0.05). No statistical difference was found between the two groups in new caries or recurrent caries (PR group: 37.1%, DGA group: 39.3%), secondary caries (PR group: 4.1%, DGA group: 2.3%), and failure of the restoration (PR group:1.5%, DGA group: 2.7%).</p><p><b>CONCLUSIONS</b>Each behavior management technique has advantages and drawbacks, and no statistical differences were found in the treatment results between the two techniques.</p>
