Autism is characterized with an abnormality of reciprocal social relatedness and of communication development. Also, autistic children show repetitive and stereotypical behavior pattern and deficiency of endurance against change. Dental problems related to autism are self-injury and trauma from accidents. Sometimes self-injury is due to discomfort resulting from restoration and local anesthesia. Also, gingivitis and multiple caries are common because of poor oral hygiene. Autistic children are anxious about visual and auditory stimuli because they don't understand the dental procedure. If the face of any changes in their daily life, their behavior becomes uncontrollable. In a setting such as the outpatient office, an autistic child's uncontrollable behavior makes it difficult to carry out proper treatment. If they need treatment under general anesthesia, it is very difficult to manage them in a ward as they are severly anxious about being admitted to a hospital. Therefore it is necessary to treat these children according to a specific management program under general anesthesia in an outpatient office. This case study reports of a 14 year old autistic teenager who although became uncontrollable because of the pain from multiple caries and from anxiety of the dental treatment eventually received treatment under general anesthesia and under conscious sedation in an outpatient office.

Objectives: The aim of the study was to evaluate the 5-year clinical performance of occlusal carious restorations using nanofill and microhybrid composites, in combination with 3-step etch-and-rinse adhesives, in patients who were going to commence orthodontic treatment. Materials and Methods: A total of 118 restorations for occlusal caries were conducted prior to orthodontic treatment. Occlusal restorations were performed both with Filtek Supreme XT (3M ESPE) and Filtek Z250 (3M ESPE) before beginning orthodontic treatment with fixed orthodontic bands. Restorations were clinically evaluated at baseline and at 1, 2, 3, 4, and 5-year recalls. Results: None of the microhybrid (Filtek Z250) and nanofill (Filtek Supreme XT) composite restorations was clinically unacceptable with respect to color match, marginal discoloration, wear or loss of anatomical form, recurrent caries, marginal adaptation, or surface texture. A 100% success rate was recorded for both composite materials. There were no statistically significant differences in any of the clinical evaluation criteria between Filtek Z250 and Filtek Supreme XT restorations for each evaluation period. Conclusions: The composite restorations showed promising clinical results relating to color matching, marginal discoloration, wear or loss of anatomical form, recurrent caries, marginal adaptation, and surface texture at the end of the 5-year evaluation period.

This study investigated the antimicrobial activity of soy protein isolate (SPI) film containing green tea extract (GTE, 1-4%, w/w) on dental caries-inducing bacterium (Streptococcus mutans), food pathogenic (Staphylococcus aureus, Escherichia coli 0157, Salmonella typhimurium), and spoilage (Pseudomonas aeruginosa) bacteria. The physical and mechanical properties of the SPI film containing GTE were also studied. The SPI film containing GTE (4%, w/w) exhibited good antimicrobial activity against S. mutans and S. aureus. The antimicrobial activity of the SPI film containing GTE increased against S. mutans as the concentration of GTE increased up to 4%(w/w). SPI films containing GTE showed lower tensile strength and elongation, and higher total soluble matter than those of control SPI film. Therefore, GTE can be used as one of antimicrobial agents for anti-dental caries and food packaging films.

The effectiveness of dental implants in patients with disability, who are non-compliant during treatment, is controversial because of their poor oral health. Thus, oral health-care and management in such patients is concerning. Moreover, limited information is available on prognosis after implant placement. Herein, we describe a patient with schizophrenia who underwent dental implantation under multiple inductions of general anesthesia (5 times) and required conservative treatment and tooth extraction for multiple dental caries and retained roots because of inadequate oral health-care. Postoperatively, fracture of the prosthodontics and progression of dental caries were observed, and with 3 additional inductions of general anesthesia, conservative treatment, implant surgery, and prosthesis implantation were conducted. Postoperative 12-month follow-up since the last prosthesis implantation showed successful results. For patients with schizophrenia, multiple implantation can reduce horizontal bone loss and achieve aesthetic results compared to treatment with removable prosthodontics and could serve as an alternative treatment modality.

Actinomycosis is a chronic infectious disease, which is produced by Gram-positive anaerobic organisms, actinomycetes, normally inhabit in the mouth, bowel and female genital tract. Primary endobronchial actinomycosis is relatively rare infection and can be misdiagnosed as endobronchial tuberculosis or malignancies. We experienced a case of primary endobronchial actinomycosis in a 49-year-old man presented with fifteen-days history of hemoptysis and cough. He had a past history of extraction of teeth because of dental caries six months ago. Chest X-ray showed irregular consolidation ad bronchoscopic findings revealed nearly obstruction by tumor mass with active bleeding in RLL. Pathologic finding of the bronchial mass showed sulfur granule with granulation tissue formation. Intravenous administration of penicillin G followed by oral ampicillin therapy for 6 months resulted in marked improvement in symptoms and chest X-ray findings. We report this case with review of literature.

Objectives: This study was conducted to find the relationship between oral health conditions of elderly people and closures of public dental health clinics in rural areas. Methods: Oral examinations and surveys were conducted in 2011 from May 11 through November 4 on 383 seniors over 65-years and under 74 years old. Results: The results of this study were as follows: 1. The results of comparative analysis of the usage behaviors of health clinics of subjects in relation to the closures of public dental clinics within the area showed that the usage level and frequency of public health agencies in areas with public dental clinics were high, and that the trend of influence on personal oral health conditions and improvement in prevention was high. When compared to 3 years ago, there was an 11.6 percentage point reduction in areas without public dental clinics (24.4%) compared to areas with public dental clinics (12.8%). 2. The results of comparative analysis of the oral health conditions and behaviors of subjects in relation to the closures of public dental clinics showed that the level of dental caries was high in areas with no public dental clinics, and the number of toothbrush usage and oral health supplemental product usage were shown to be high in areas with public dental clinics. Conclusion: The closures of public dental clinics were found to affect oral health behavior and conditions of elderly people in rural areas.

Objectives : School-age children have mixed dentition and are sensitive to dental caries. Their dental condition is more important as it is directly related with oral health in their life, and parents' attention and education are necessary as the children can not manage their oral health voluntarily. Methods : To evaluate the effect of parents' occupational status on the oral health of children, this study conducted a questionnaire survey and analyzed the results along with the results of oral examination with 952 students and their parents of an elementary school located in Ulsan conducting school oral health projects on May, 2009. Results : As dental caries prevalence rate recorded 33.7%, 56.8% and 66.9% in non-dual income, professional dual income and non-professional dual income families, respectively, the rate of children of dual income families was significantly higher than that of non-dual income ones (p<0.05). Conclusions : For professional dual income families, although working mothers contribute to economic stability, they took less time to care or to educate their children compared to no-working mothers so that they need to pay more attention to oral health of children. In addition, more interest to and education for children of non-professional dual income families showing relatively lower socio-economic level and lack of time for children, were also necessary in school projects on oral health education and prevention.
