Background:This study examined the effects of three different treatment doses of a motor skill intervention (the Children’s Health Activity Motor Program [CHAMP]) on changes in preschoolers’ motor performance.Methods:Onehundred and nine children were divided into one of four groups: control and three CHAMP dosage groups: T1, 660 min; T2, 720 min; or T3, 900 min. Motor performance was assessed before and after the intervention using the Test of Gross Motor Development, 2nd Edition (TGMD-2). We used a 2 (time) × 4 (treatment) mixed-measures ANOVA to determine interaction and main effects. Significant interactions were decomposed using separate one-way between groups ANOVAs at each time point followed by Tukey’s post hoc tests.Results:Results revealed a significant time × treatment interaction (F3, 100 = 16.79; p < .001). There were no differences across treatment groups before the intervention (F3, 100 = .075, p < .90), but after the intervention the control group had significantly lower TMGD-2 scores compared with all three CHAMP intervention groups (F3, 100 = 9.92, p < .001, all post hoc tests, p < .001). Posttreatment differences can be attributed to greater improvements in motor performance following the CHAMP intervention regardless of specific dosage.Conclusions:Motor performance scores for all children who completed CHAMP significantly improved.

Motor Skill Intervention

Fundamentado em teorias de motivação (Ames, 1987, 1992a, b; Epstein, 1988, 1989; Nicholls, 1984) o objetivo deste estudo foi determinar a influência de uma intervenção motora, com técnica de motivação orientada para a maestria (TMOM), no desenvolvimento motor e na percepção de competência física de crianças com idades entre seis e 10 anos que demonstraram atrasos motores previamente identificados. Noventa e uma crianças com atrasos motores foram aleatoriamente distribuídas em dois grupos: intervenção (N = 41) e controle (N = 50). Os participantes do grupo de intervenção foram submetidos a 12 semanas (duas sessões semanais). Ao início e término da intervenção, todos os participantes realizaram o Test o f Gross Motor Development - TGMD organizado por Ulrich (1985). Os participantes que experienciaram a intervenção também responderam a Pictorial Scale of Perceived Competence and Social Acceptance - PSPCSA (Harter & Pike, 1984) no início e no término da intervenção. A influência da intervenção na percepção de competência física foi avaliada através de ANOVA com medidas repetidas. Os resultados evidenciaram que a intervenção promoveu mudanças significantes e positivas em relação à percepção de competência física de meninos e meninas com atrasos no desenvolvimento motor. A ênfase na TMOM propicia ao professor oportunidades para criar experiências motoras que suprem as necessidades de todas as crianças, indiferentes de suas experiências prévias e diferentes níveis de habilidades, promovendo a autonomia das crianças colocando-as como sujeitos de suas conquistas. Em outras palavras, permite as crianças explorarem seu próprio processo de aprendizagem

Purpose: Motor skill interventions are effective for improving young children’s fundamental motor skills, but less is known regarding if boys and girls equally benefit from these interventions. The purpose of this study was to compare changes in preschool-aged boys’ and girls’ fundamental motor skills across an intervention. Methods: Sixty-eight children (Mage = 4.4 years, SD = 0.44) participated in the study and completed the Test of Gross Motor Development 2nd Edition before and after a 600-minute Children’s Health Activity Motor Program (CHAMP) intervention. All girls’ (n = 27) and a random subsample of boys’ (n = 27) total, locomotor subtest, object control skill subtests, and individual skills were compared before (pre) and after (post) CHAMP. Potential sex differences in treatment effects were examined by sex by treatment interactions from repeated measures ANOVA, and potential sex differences in individual skills before, after, and across (change) were examined using MANOVAs. Results: Boys and girls had similar motor skills before and after the intervention. Boys and girls had higher scores at posttest, and CHAMP was equally effective for boys and girls. Boys outperformed girls on the run and kick (p < .05) at posttest. Conclusion: Findings support that CHAMP improves skills for both preschool boys and girls.

The purpose of this study was to investigate the effects of guided play and free play in an enriched environmentintervention programs using motor skill development in kindergarten children. Seventy-one children attending kindergarten classes were assigned to two experimental groups and one control group. Participants performed the Test of Gross Motor Development-2 before and after the intervention period. Results revealed that both boys and girls in the guided play group showed motor skill improvement, whereas no changes were observed in motor development in the boys and girls assigned to the free play in enriched environment group, nor in those in the control group. These findings indicate that the teacher's role in the guided play intervention was crucial to help preschool children to improve their performance.

Level Of Agreement

This study compared preschoolers’ fundamental motor skills (FMS) on the Test of Gross Motor Development 2nd and 3rd editions (TGMD-2 and TGMD-3) before (pretest) and after (posttest) a motor skill intervention. This study also compared FMS changes (TGMD raw and percentile scores for total score, and locomotor and object control/ball subscales) across the intervention when FMS were measured using the two editions. Sixty-four preschoolers ( Mage = 4.4, SD = 0.44 years) completed the TGMD-2 and TGMD-3 before and after a motor skill intervention. We determined the level of agreement between assessments using intra-class correlations (ICC), Lin’s Concordance Correlation Coefficient, and Bland-Altman plots. Overall, our results support an acceptable relative agreement between the TGMD-2 and TGMD-3 for raw scores, but there were variable strengths of agreement (by subscales) for percentile scores. Both assessments supported the efficacy of the intervention. This consistent demonstration of efficacy but varied strength of agreement suggests that the TGMD-2 and TGMD-3 are similar but not interchangeable.

The thermoplastic nylon denture base material is prone to discoloration because its amide bonds absorb water easily. Titanium dioxide (TiO2) nanoparticle have long been used as a denture base coating. Meanwhile, coffee contains chlorogenic and tanic acid, which can change the color of denture bases. The purpose of this study was to examine the effect TiO2 coating and duration of coffee immersion on discoloration of thermoplastic nylon denture base. Samples consisted of 24 thermoplastic nylon in square-shaped (30 x 30 x 2 mm), divided into 4 groups (n = 6). They were control (without TiO2 coating) and treatment (with TiO2 coating) groups, which then were immersed in coffee solution for 15 and 30 days. Discoloration test was conducted using spectrophotometer by measuring the delta absorbance of light before and after coffee immersion. The result showed that the lowest delta absorbance was in the 15-day treatment group (0.011 ± 0.005) and the highest was in the 30-day control group (0.077 ± 0.027). Two-way ANOVA test showed that TiO2 coating and coffee immersion had an effect on discoloration of thermoplastic nylon (p <0.05). Post hoc LSD test showed that there were significant differences between the control and treatment group at 15 and 30 days of coffee immersion (p <0.05). In conclusion, TiO2 as a thermoplastic nylon denture base coating can reduce discoloration by coffee immersion for 15 and 30 days. There were no differences between 15 and 30 days of coffee immersion on thermoplastic nylon’s discoloration in the control and treatment groups.

The current study evaluated the effectiveness of a motor program that specifically targeted fundamental motor skills (FMS) in children with ASD. The experimental group (n=21) participated in a 9-week program with motor instructions for 80 minutes/day, three days/week, while the control group (n=29) did not participate in the program. We measured FMS (using the Test of Gross Motor Development-3) one-week before, one-week after, and two-months after the program. Children in the experimental group had significantly larger FMS improvements than the controls on both locomotor and ball skills immediately following the program, and these participants showed continuous improvement on locomotor, but not ball skills, at 2-months follow-up. In individual analyses, 80% of children in the experimental group versus 29% of children in the control group showed continuous locomotor skills improvement beyond their pre-test levels. These findings highlight the importance of both a long-term motor development intervention and an individualized approach for evaluating improved FMS among children with ASD.

Abstract Background In this research the biomechanical properties of a bone model was examined. Porcine ribs are used as experimental model. The objective of this research was to investigate and compare the biomechanical properties of the bone model before and after implant placement. Methods The bone samples were divided in three groups, Group 1 where ALL-ON-FOUR protocol was used during pre-drilling and placing the implants, Group 2 where ALL-ON-FOUR protocol was used during pre-drilling, and implants were not placed, and Group 3 consisting of intact bones served as a control group. Static and dynamic loading was applied for examining the model samples. Kruskal–Wallis statistical test and as a post-hoc test Mann–Whitney U test was performed to analyze experimental results. Results According to the results of the static loading, there was no significant difference between the implanted and original ribs, however, the toughness values of the bones decreased largely on account of predrilling the bones. The analysis of dynamic fatigue measurements by Kruskal–Wallis test showed significant differences between the intact and predrilled bones. Conclusion The pre-drilled bone was much weaker in both static and dynamic tests than the natural or implanted specimens. According to the results of the dynamic tests and after a certain loading cycle the implanted samples behaved the same way as the control samples, which suggests that implantation have stabilized the skeletal bone structure.

Many interventions feature a singular component approach to targeting children’s motor competency and proficiency. Yet, little is known about the use of integrative interventions to meet the complex developmental needs of children aged 3–6 years. The purpose of this study was to examine the effects of an integrative universally designed intervention on children with and without disabilities’ motor competency and proficiency. We selected children (N = 111; disability = 24; no disability = 87) to participate in either a school-based integrative motor intervention (n = 53) or a control condition (n = 58). Children in the integrative motor intervention both with and without disabilities showed significant improvement in motor competency and proficiency (p < .001) as compared with peers with and without disabilities in a control condition. Early childhood center directors (e.g., preschool and kindergarten) should consider implementing integrative universally designed interventions targeting multiple aspects of motor development to remediate delays in children with and without disabilities.

Abstract The aim of this study was to compare the efficacy of grape seed extract (GSE), calcium hypochlorite [Ca(ClO)2], and sodium hypochlorite (NaOCl) irrigant solutions with rotary or reciprocating instrumentation for disinfection of root canals inoculated with Enterococcus faecalis. The mesiobuccal root canals of mandibular molars were prepared and inoculated with Enterococcus faecalis for 21 days. The roots were then randomly divided into the following eight experimental groups (n=11) according to the instrumentation technique and disinfection protocol: ProTaper Next or Reciproc R25 with sodium chloride (control group), 6% NaOCl, 6% Ca(ClO)2, or 50% GSE used for irrigation during instrumentation. The antimicrobial activity was determined on the basis of a reduction in colony-forming units (CFUs) counted on bacterial samples collected before and after root canal instrumentation and expressed as a percentage of reduction. Data were evaluated by two-way ANOVA followed by Tukey HSD post-hoc tests (p<0.05). No significant differences were observed in bacterial reduction between the ProTaper Next and Reciproc R25 systems (p>0.05), regardless of the irrigant solution used. Furthermore, all active solutions (6% NaOCl, 50% GSE, and 6% Ca(ClO)2) showed similar potential to reduce bacterial counts (p>0.05) and were significantly more effective than sodium chloride (control) (p<0.05). The results suggest that the GSE and Ca(ClO)2 have potential clinical application as irrigant solutions in endodontic therapy since they present bactericidal efficacy against Enterococcus faecalis.

Contaminated water often affects the occurrence of periodontitis in the coastal area. The diabetic hypercholesterolemia-induced periodontitis in Indonesia is very high. The use of coenzyme Q10 to treat this disease has never been investigated yet. Therefore, this study aimedto analyze the effect of coenzyme Q10 on the lipid profile of diabetic hypercholesterolemia-induced periodontitis.Twenty four rats were randomized into 6 groups (G1-G6). The groups (G1-G3) are healthy, negative and positive control group respectively. The treatment groups (G4-G6) are diabetic hypercholesterolemia-induced rats given coenzyme q10 dose of 13,5; 27 and 54 mg/kg respectively. Rats were induced by periodontitis, hypercholesterolemia and diabetes mellitus. Coenzyme Q10 was administered orally using 2 mL gastric tube once a day for 14 days. Lipid profile including triglycerides, HDL, and atherogenic index (IA) was measured enzymatically by the CHOD-PAP method. Data were analyzed by one-way ANOVA test and followed by the Least Significant Difference (LSD) post hoc test.Coenzyme Q10 with a dose of 54 mg/kgis effective in lowering triglyceride, and atherogenic index and increasing HDL level in diabetic hyperlipidemia-induced periodontitis rats model. This research supports the potential effects of coenzyme Q10 supplementation to improve lipid profile in diabetic hypercholesterolemia-induced periodontitis in the coastal area.
