The periodontal status of all subjects was recorded using the Community Periodontal Index of Treatment Need (CPITN) with a slight modification. The orthodontic treatment need was determined using the Dental Aesthetic Index (DAI). Chi-square test and odds ratio were used for statistical analysis.Results: No significant sex differences were found in the autistic or nonautistic groups. The autistic children presented with a significantly poorer periodontal status than the nonautistic children (P<.05). No significant differences in terms of the various malocclusion categories were found between both groups (P>.05); however, children with autism showed missing teeth, spacing, diastemas, reverse overjets, open bites, and Class II molar relationship tendencies in a higher percentage than nonautistic individuals. In all, autistic children and nonautistic children frequently needed orthodontic treatment.Conclusion: This study suggests that children with autism require special dental management to improve their oral hygiene as well as their dental esthetics. More care from parents, general dentists, and pedodontists/orthodontists should be provided routinely to autistic children.","PeriodicalId":87213,"journal":{"name":"World journal of orthodontics","volume":"11 3","pages":"256-61"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29309860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample consisted of patients between 8 and 13 years of age randomly divided into two groups. One group was treated with spring-loaded bite blocks while the other received treatment with magnetic bite blocks. Further, a group matched for age, sex, and mandibular plane angle served as a control. The treatment effects were evaluated clinically and cephalometrically and by electromyographic (EMG) examination of the masseter and temporalis muscles after 8 months. Both appliances showed significantly (P<.05) favorable orthopedic effects. The spring-loaded bite blocks closed the existing open bite by 3.3 mm on average with a significant maxillary incisor extrusion and molar intrusion. Magnetic bite blocks produced an average of 4.9 mm of open bite closure with significant intrusion of the molars in both arches. Overall, both appliances significantly enhanced condylar growth, altered it to a more anterosuperior direction, and produced significant true forward mandibular rotation. Significant increases in masseter and temporalis muscle activity at rest and maximum clenching were noted in both groups, which could be a positive factor in retaining the achieved result. After 10 months of retention with passive bite blocks, cephalograms indicated only an insignificant relapse.","PeriodicalId":87213,"journal":{"name":"World journal of orthodontics","volume":"11 2","pages":"107-16"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29059947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sixty-six 0.016 3 0.022-inch Ni-Ti wires were tested after being used intraorally for 6 weeks using two protocols. Thirty-three wires were evaluated after the use of fluoride-containing Crest toothpaste (sodium fluoride 0.243%, 0.15% w/v fluoride ion) and Equate fluoride rinse (sodium fluoride 0.05%, fluoride ion 0.0226%). Another 33 wires were examined after a nonfluoridated natural toothpaste (Tom's of Maine; calcium carbonate, xylitol, myrrh, propolis, sodium lauryl sulfate, carrageenan, spearmint and peppermint oils, glycerin, and water) was used. Another 34 Ni-Ti wires served as a control; they were tested as received. Statistical analyses were carried out with a linear-mixed model (analysis of variance [ANOVA]).Results: Force degradation occurred within both groups of intraorally used wires but not in the unused archwires. When compared to unexposed wires, those with fluoride exposure exhibited slightly higher force degradation at 3.1 and 3.0 mm deflection, but they displayed less force degradation at 0.5 and 1.0 mm deflection.Conclusions: Topical fluoride regimens decreased the unloading property of Ni-Ti wires at higher deflections but increased it at lower deflections.","PeriodicalId":87213,"journal":{"name":"World journal of orthodontics","volume":"11 2","pages":"135-41"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29058171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paired- and independent-sample t tests were used for statistical evaluation.Results: Combined RME and face mask therapy produced significant and favorable skeletal changes in both arches.

Conventional stainless steel brackets were used as controls.Results: In both dry and wet states, PCA and MCS brackets expressed a statistically significant higher F value with respect to stainless steel and PCA-M brackets when combined with the rectangular archwires (P<.01). PCA brackets showed significantly higher friction than MCS brackets (P<.01) when coupled with 0.014 x 0.025-inch nickel-titanium (Ni-Ti) archwire. SEM analysis showed differences in the surfaces among stainless steel, MCS, PCA-M, and PCA brackets. In the wet state, the mean F values were generally higher than in the dry state.Conclusion: PCA brackets showed significantly higher F than MCS brackets only when combined with 0.014 x 0.025-inch Ni-Ti archwires.
