Evaluation of novel programs in health counseling – their effectiveness in the oral health of young children, and their acceptance by parents and professionals in public dental service.

Aim and design: To evaluate family-based health counseling for young children, and to study the significance of adding parental self-care or the training of professionals to the programs. The effectiveness and acceptability of the programs were evaluated by comparing two new programs with an earlier one. Subjects and methods: The study was carried out in Vantaa, which was divided into three study areas. The subjects consisted of children born in 2008, particularly fi rstborn children, while children born in 2006 formed the historical control. The fi rst of the new programs emphasized oral hygiene and use of fl uoride, and the second program focused on proper diet and use of xylitol. The main outcome measure was mutansstreptococci (MS) in the dental biofi lm of two-year-olds, and the opinions of parents and dental professionals were evaluated using questionnaires. Results: The programs found wide acceptance among dental professionals. There were no group-related differences found in the MS scores of the two-year-olds. However, all groups combined, father’s advanced level of education and child’s proper use of xylitol were associated with negative MS scores. In the opinion of parents, the oral healthcare guidance at least somewhat met their expectations. Conclusions: The present fi ndings suggest that providing training and support for professionals in health education is important. The addition of parental self-care to supplement programs aimed at young children does not improve the program, although it may improve parental readiness to change their own health habits. Counseling for families might be best carried out through a routine patient-centered program.

Improving oral healthcare in Scotland with special reference to sustainability and caries prevention

Brett Duane Improving oral healthcare in Scotland with special reference to sustainability and caries prevention University of Turku, Faculty of Medicine, Institute of Dentistry, Community Dentistry, Finnish Doctoral Program in Oral Sciences (FINDOS-Turku), Turku, Finland Annales Universitatis Turkuensis, Sarja- Ser. D, Medica-Odontologica. Painosalama Oy, Turku, Finland, 2015. Dentistry must provide sustainable, evidence-based, and prevention-focused care. In Scotland oral health prevention is delivered through the Childsmile programme, with an increasing use of high concentration fluoride toothpaste (HCFT). Compared with other countries there is little knowledge of xylitol prevention. The UK government has set strict carbon emission limits with which all national health services (NHS) must comply. The purpose of these studies was firstly to describe the Scottish national oral health prevention programme Childsmile (CS), to determine if the additional maternal use of xylitol (CS+X) was more effective at affecting the early colonisation of mutans streptococci (MS) than this programme alone; secondly to analyse trends in the prescribing and management of HCFT by dentists; and thirdly to analyse data from a dental service in order to improve its sustainability. In all, 182 mother/child pairs were selected on the basis of high maternal MS levels. Motherswere randomly allocated to a CS or CS+X group, with both groups receiving Childsmile. Theintervention group consumed xylitol three times a day, from when the child was 3 months until 24 months. Children were examined at age two to assess MS levels. In order to understand patterns of HCFT prescribing, a retrospective secondary data analysis of routine prescribing data for the years 2006-2012 was performed. To understand the sustainability of dental services, carbon accounting combined a top-down approach and a process analysis approach, followed by the use of Pollard’s decision model (used in other healthcare areas) to analyse and support sustainable service reconfiguration. Of the CS children, 17% were colonised with MS, compared with 5% of the CS+X group. This difference was not statistically significant (P=0.1744). The cost of HCFT prescribing increased fourteen-fold over five years, with 4% of dentists prescribing 70% of the total product. Travel (45%), procurement (36%) and building energy (18%) all contributed to the 1800 tonnes of carbon emissions produced by the service, around 4% of total NHS emissions. Using the analytical model, clinic utilisation rates improved by 56% and patient travel halved significantly reducing carbon emissions. It can be concluded that the Childsmile programme was effective in reducing the risk for MS transmission. HCFT is increasing in Scotland and needs to be managed. Dentistry has similar carbon emissions proportionally as the overall NHS, and the use of an analytic tool can be useful in helping identify these emissions. Key words: Sustainability, carbon emissions, xylitol, mutans streptococci, fluoride toothpaste, caries prevention.

Probiotics and oral health: In vitro and clinical studies

Aino Toiviainen Probiotics and oral health: in vitro and clinical studies University of Turku, Faculty of Medicine, Institute of Dentistry, Periodontology, Finnish Doctoral Program in Oral Sciences (FINDOS-Turku), Turku, Finland Annales Universitatis Turkuensis, Sarja – Ser. D, Medica-Odontologica. Painosalama Oy, Turku, Finland, 2015 Probiotics are used, for example, to prevent and treat diarrhea, allergies and respiratory infections, and there is an increasing interest to use probiotics also for oral health purposes. The most commonly used probiotic bacteria are lactobacilli and bifidobacteria, which are acidogenic and aciduric. From the oral point of view, use of these probiotics may, at least in theory, mean an increased risk of caries. In this thesis, the effects of probiotics on oral microbial composition, acid production of dental plaque and gingival health were studied through in vitro studies and two clinical studies. In a randomized, double-blind and crossover study, 13 healthy adults were allocated into two groups. Half of the subjects first consumed Lactobacillus rhamnosus GG tablets twice a day for two weeks, and after the washout period, L. reuteri tablets twice a day for two weeks. The other half of the subjects used the tablets in reverse order. In another controlled, randomized and double-blind study, 62 healthy adults were allocated into two groups. One group used the test tablets containing L. rhamnosus GG and B. lactis BB-12 and the other group used control tablets without probiotics. The recommendation for the use of the tablets was 4 per day for 4 weeks. Probiotic lactobacilli interfered with S. mutans biofilm formation and the adhesion of S. mutans to saliva-coated hydroxyapatite in vitro. No effect was found in S. mutans levels in the three-species biofilms. In clinical studies, the studied probiotics had no effect on the acid production of plaque. The counts of mutans streptococci and the oral microbial composition remained the same. Tablets containing L. rhamnosus GG and Bifidobacterium animalis subsp. lactis BB-12 did decrease the amount of plaque and gingival bleeding. According to our results, it seems that probiotics have beneficial effects on gingival health. The present results confirmed that probiotics are safe and have beneficial effects on oral health. Since the consumption of probiotics by the general population is steadily increasing, an understanding of the functions of probiotics in the oral cavity has become more important.

Estudo de fibras alimentares em frutas e hortaliças para uso em nutrição enteral ou oral

Dietas enterais com alimentos convencionais são usadas em nutrição domiciliar para fornecer macronutrientes, obter dietas individualizadas e de menor custo. O objetivo deste trabalho foi estudar frutas e hortaliças (alface, berinjela, cenoura, chicória, goiaba e tamarindo) como fontes de fibras alimentares solúveis e insolúveis para serem usadas em nutrição enteral ou suplemento nutricional oral. As hortaliças e frutas foram adicionadas a uma formulação enteral domiciliar e também preparadas em solução com água. Foram determinadas a composição centesimal, as fibras solúveis e insolúveis dos alimentos, a atividade de água e o pH das formulações. Foram realizados testes de gotejamento das formulações com os alimentos experimentais. A melhor proporção de alimento/dieta enteral domiciliar foi de 100 g/2 L para dieta enteral e de 150 g/2 L para suplemento nutricional oral (ingestão por boca). As quantidades de cada alimento adicionadas à formulação enteral equivalem a duas porções (100 g) diárias de cada alimento para 2 L e 2000 kcal. A maior contribuição para aumentar a quantidade de fibras foi da goiaba e a menor, da berinjela. Os valores de atividade de água ficaram entre 0,95 e 1,00, indicando que as dietas são susceptíveis à contaminação microbiana. Nessas condições, devem ser consumidas imediatamente após o preparo.

Carriage of herpes simplex virus and human papillomavirus in oral mucosa is rare in young women: a long-term prospective follow-up

Herpes simplex -virus 1 (HSV-1) ja ihmisen papilloomavirus (HPV) infektoivat suun epiteelisoluja. Useimmissa tapauksissa näiden virusten infektio on kliinisesti oireeton. Suun limakalvojen oireeton HPV-infektio on aikuisilla yleinen, ja valtaosa näistä infektioista ovat ohimeneviä ja vain pieni osa johtaa krooniseen HPV-infektioon. Krooninen HPV-infektio lisää riskiä epiteelisolujen transformoitumiseen kohti syöpäsolua. HPV infektio ei ole yksinään riittävä aiheuttamaan syöpäsolun, vaan siihen tarvitaan myös muita riskitekijöitä.. Muut infektiot, kuten esimerkiksi HSV-1-infektio saattaa olla yksi näistä riskitekijöistä. Tämän syventävän opinnäytetyön tutkimuksen tavoitteena oli selvittää HSV-1-infektion esiintymistä naisten suun limakalvonäytteissä kuuden vuoden seurannassa. Toinen tavoitteemme oli selvittää HSV-1 ja HPV -yhteisinfektion esiintymistä suun epiteelisoluissa, erityisesti naisilla joilla havaittiin suun krooninen HPV-infektio. Tämä tutkimus on osa kuusivuotista seurantatutkimusta (Finnish Family HPV -tutkimus), joka suunniteltiin selvittämään HPV-infektioiden dynamiikkaa ja riskitekijöitä 329 suomalaisperheessä. Suun limakalvoilta otettiin harjausnäyte ennen synnytystä ja kuusi kertaa synnytyksen jälkeen kuuden vuoden aikana. Näytteistä eristettyä DNA:ta oli saatavilla riittävästi HSV-1-analyysiä varten yhteensä 304 naiselta (keski-ikä 25.6 vuotta). Kaikkiaan tutkittavia näytteitä oli 1,873, joista HSV-1:n esiintyminen tutkittiin käyttäen kvantitatiivista PCR:ää. Lisäksi epävarmat PCR-tulokset varmistettiin PCR-tuotteen Southern Blot hybridisaatiolla. HSV-1 tuloksia verrattiin aikaisemmin saatuihin HPV-tuloksiin. Suun limakalvonäytteistä 2.2% oli HSV-1-positiivisia ja 19.6% oli HPV-positiivisia. Yhteensä 11.8%:lla äideistä suunäyte oli HSV-1-DNA -positiivinen ainakin kerran seurannan aikana. HSV-1 ja HPV -yhteisinfektio löydettiin vain neljältä äidiltä. Suurin osa äideistä, jotka olivat HSV-1-positiivisia ennen syntymää, pysyivät HSV-1-positiivisina myös synnytyksen jälkeen. Kolmella naisella todettiin persistentti HPV-16 infektio ja kahdella heistä oli samanaikainen HSV-1 infektio. Tuloksemme osoittaa, että HSV-1:n ja HPV:n esiintyminen yhtä aikaa nuorten naisten suun limakalvolla on harvinaista. On suositeltavaa, että yhteisinfektion omaavia äitejä seurataan myös tulevaisuudessa, sillä HSV-1-infektio saattaa olla yksi riskitekijä suun limakalvon malignissa muutoksessa kroonisen HPV-infektion yhteydessä.

Improving the oral health status of functionally independent and dependent seniors residing in long-term care facilities through dental hygiene education /

The purpose of this study was to evaluate the oral health status of residents residing in 2 long-term care facilities and determine if dental hygiene education was required in order to improve their current oral health. The oral health status of 6 independent and 4 dependent individuals residing in 2 long-term care facilities was evaluated. In addition, the current oral health and disease prevention practices employed by 4 caregivers who were responsible for providing oral care to dependent residents in the long-term care facilities were evaluated. Furthermore, an evaluation of the oral care practices of independent residents who were responsible for providing their own care was conducted. Finally, the challenges that caregivers and independent residents faced when performing oral care were determined, and methodological changes were proposed. Using a generic qualitative research methodology, data collection was comprised of semi structured interviews, field observations, and documentation. The oral health status of the residents was reevaluated 3 months later. The findings of this study demonstrated an increase in plaque accumulation, gingival inflammation, and unhealthy gingival tissue colour changes among the residents over the 3-month period. The study revealed that poor oral health among the residents was a result of inadequate oral hygiene care techniques, difficulties accessing oral health care, financial limitations, insufficient care staff, insufficient time for personal care duties, lack of professional development, minimal interprofessional collaboration of health disciplines, and lack of perseverance on the part of the caregivers and residents. Overall, oral health is essential, and maintaining optimal oral health requires increased collaboration and communication between health care providers.

Using dramatic activity to enhance Junior Core French students' motivation and oral communication skills /

Junior Core French students' motivation to learn a second language and students' French oral communication skills relating to drama instruction were investigated in this study. Students' increased and improved motivation and oral acquisition were measured by several forms of data collection including journals, questionnaires and surveys, interviews, outside observer and teacher observations, and anecdotal comments. The results indicated that as a result of drama integration in the Junior Core French classroom, grade 5 students, both male and female, were more motivated to participate in second language instruction, thereby increasing and improving their oral communication skills. The findings showed that more males than females reported that drama integration allowed them the opportunity to use their French speaking skills. Research shows that interactive approaches to teaching such as drama give students the motivation and enthusiasm to learn.

Effects of dietary restraint and oral contraceptives on bone strength and bone turnover in young women

ABSTRACT Introduction The purpose of this study was to assess specific osteoporosis-related health behaviours and physiological outcomes including daily calcium intake, physical activity levels, bone strength, as assessed by quantitative ultrasound, and bone turnover among women between the ages of 18 and 25. Respective differences on relevant study variables, based on dietary restraint and oral contraceptive use were also examined. Methods One hundred women (20.6 ± 0.2 years of age) volunteered to participate in the study. Informed written consent was obtained by all subjects prior to participation. The study and all related procedures were approved by the Brock University Research Ethics Board. Body mass, height, relative body fat, as well as chest, waist and hip circumferences were measured using standard procedures. The 10-item restrained eating subscale of the Dutch Eating Behaviour Questionnaire (DEBQ) was used to assess dietary restraint (van Strien et al., 1986). Daily calcium intake was assessed by the Rapid Assessment Method (RAM) (Hertzler & Frary 1994). Weekly physical activity was documented by the 4-item Godin Leisure-Time Exercise Questionnaire (Godin & Shephard 1985). Bone strength was determined from the speed of sound (SOS) as measured by QUS (Sunlight 7000S). SOS measurements (m/s) were taken of the dominant and non-dominant sides of the distal one third of the radius and the mid-shaft of the tibia. Resting blood samples were collected from all subjects between 9am and 12pm, in order to evaluate the impact of lifestyle factors on biochemical markers of bone turnover. Blood was collected during the early follicular phase of the menstrual cycle (approximately days 1-5) for all subjects. Samples were centrifliged and the serum or plasma was aliquoted into separate tubes and stored at -80°C until analysis. The bone formation markers measured were Osteocalcin (OC), bone specific alkaline phosphatase (BAP) and 25-OH vitamin D. The bone resorption markers measured were the carboxy (CTx) and amino (NTx) terminal telopeptides of type-I collagen crosslinks. All markers were assessed by ELISA. Subjects were divided into high (HDR) and low dietary restrainers (LDR) based on the median DEBQ score, and also into users (BC) and non-users (nBC) of oral contraceptives. A series of multiple one way ANOVA's were then conducted to identify differences between each set of groups for all relevant variables. A two-way ANOVA analysis was used to explore significant interactions between dietary restraint and use of oral contraceptives while a univariate follow-up analysis was also performed when appropriate. Pearson Product Moment Correlations were used to determine relationships among study variables. Results HDR had significantly higher BMI, %BF and circumference measures but lower daily calcium intake than LDR. There were no significant differences in physical activity levels between HDR and LDR. No significant differences were found between BC and nBC in body composition, calcium intake and physical activity. HDR had significantly lower tibial SOS scores than LDR in both the dominant and non-dominant sites. The post-hoc analysis showed that within the non-birth control group, the HDR had significantly lower tibial SOS scores of bone strength when compared to the LDR but Aere were no significant differences found between the two dietary restraint groups for those currently on birth control. HDR had significantly lower levels of OC than LDR and the BC group had lower levels of BAP than the nBC group. Consistently, the follow-up analysis revealed that within those not on birth control, subjects who were classified as HDR had significantly (f*<0.05) lower levels of OC when compared with LDR but no significant differences were observed in bone turnover between the two dietary restraint groups for those currently on birth control. Physical activity was not correlated with SOS scores and bone turnover markers possibly due to the low physical activity variability in this group of women. Conclusion This is the first study to examine the effects of dietary restraint on bone strength and turnover among this population of women. The most important finding of this study was that bone strength and turnover are negatively influenced by dietary restraint independent of relative body fat. In general, the results of the present thesis suggest that dietary restraint, oral contraceptive use, as well as low daily calcium intake and low physical activity levels were widespread behaviours among this population of college-aged women. The young women who were using dietary restraint as a strategy to lose weight, and thus were in the HDR group, despite their higher relative body fat and weight, had lower scores of bone strength and lower levels of markers of bone turnover compared to the low dietary restrainers. Additionally, bone turnover seemed to be negatively affected by oral contraceptives, while bone strength, as assessed by QUS, seemed unaffected by their use in this population of young women. Physical activity (weekly energy expenditure), on the other hand, was not associated with either bone strength or bone tiimover possibly due to the low variability of this variable in this population of young Canadian women.

Deviance of syntax in oral languages and oral reading behavior

The major hypothesis of this paper is that any deviance in syntax present in oral language will be evident in oral r eading behaviour. Using Lee and Canter's Developmental i 1 Sentence Scoring technique (1971) and Y. Goodman and Burke's Reading Miscue Inventory (1972) linguistic competence was established in t hree male children. ages 10 to 11. patterns of strengths and weaknesses in reading were determined. and the relationships t hat were established, were examined. Results of the study i ndicate that oral language behaviour is closely tied to oral r eading behaviour. This type of approach can be used as a basis for a diagnosis of a reading difficulty and then a prescription for language and reading skills.

Astringency and other oral sensations : biological sources of individual variation and association with food and beverage behaviour

Orosensory perception strongly influences liking and consumption of foods and beverages. This thesis examines the influence of biological sources of individual variation on the perception of prototypical orosensory stimuli, food liking, self-reported alcohol liking and consumption, and indices of health. Two orosensory indices were examined: propylthiouracil (PROP) responsiveness, a genetically-mediated index of individual variation associated with enhanced responsiveness to orosensory stimuli often expressed as PROP taster status (PTS); and thermal taster status (TTS), a recently reported index of orosensory responsiveness. Taster status in PTS and/or TTS confers greater responsiveness to most orosensory stimuli. Gender, age, ethnicity, and fungiform papillae (FP) density were not associated with orosensory responsiveness to tastants, an astringent, and a flavour. Unlike PROP responsiveness, FP density was not associated with TTS. Both PROP responsiveness and TTS were associated with increased responsiveness to orosensory stimuli, including temperature and astringency. For PROP, this association did not hold when stimuli were presented at cold or warm temperatures, which are ecologically valid since most foods and beverages are not consumed at ambient temperature. Thermal tasters (TTs), who perceive 'phantom' taste sensations with lingual thermal stimulation, were more responsive to stimuli at both temperatures than thermal non-tasters (TnTs). While PTS, TIS, and gender affected self-reported liking and consumption of some alcoholic beverages, gender associated with the greatest number of beverage types and consumption parameters, with males generally liking and consuming alcoholic beverages more than females. Age and gender were the best predictors of alcoholic beverageAiking and consumption. As expected, .. liking of bitter and fatty foods and cream was inversely related to PROP responsiveness. TTS did not associate with body mass index or waist circumference, and contrary to previous studies, neither did PROP responsiveness. Taken together, TnTs' greater liking of cooked fruits and vegetables and high alcohol, and astringent alcoholic beverages than TTs suggests differences between TTS groups may be driven by perceived temperature and texture. Neither an interaction between PTS and TTS nor a TTS effect on PROP responsiveness was observed, suggesting these two indices of individual variation exert their influences on orosensory perception independently.

The Effects of Drama on Oral Fluency and Foreign Language Anxiety: An exploratory study

Previous research has suggested that drama has positive effects on learners' oral communication and anxiety; however, it is unclear which dimensions, or to what extent, they are affected by drama. This research narrows the investigation by examining how a drama-based EFL program impacts three dimensions of oral communication: fluency, comprehensibility, and accentedness, and one anxiety factor - foreign language speaking anxiety (FLSA) -, over time. Speech samples were collected from EFL learners in a treatment and a control group, and subsequently assessed by untrained Canadian-born raters. FLSA levels were measured through questionnaires and interviews. Pre- and post-test analysis indicate that learners in the treatment group made significant gains in oral fluency while oral fluency among learners in the control group remained unchanged. There was a significant reduction in FLSA levels among learners in both groups. Finally, qualitative analyses suggest that drama activities, among others, enhance learners' comfort levels in speaking English.

Oral French Communication in French Immersion Canadian and World Studies Classrooms: A Primer for Educators

This project presents a primer for secondary French Immersion teachers that facilitates the use of French oral communicative activities in secondary Canadian and World Studies courses. The primer supports collaborative and inclusive teaching strategies that invite students to speak and develop their oral French communication skills. The primer is divided into 2 main components: (a) Rationale for the Primer, and (b) the Strategies themselves, comprising succinct descriptions as well as potential uses and suggestions. A critical content analysis of various Ontario Ministry of Education documents was undertaken in order to explore the importance of oral communication in second-language learning in Ontario secondary schools. Furthermore, holistic and invitational education perspectives were examined in order to define the advantages of collaborative learning. Moreover, research in the stream of French Immersion studies was also referenced to frame the relevance of second-language learning and the significant role the French Immersion teacher plays. The aforementioned research contributes to the advancement of theory and practice regarding the importance of opportunities for oral French communication in secondary Canadian and World Studies courses.
