Effect of a 2-week Sugar Stress on Bacterial Profiles in Whole Saliva

Dental caries is a non-communicable biofilm-mediated disease affecting both crown and exposed root surfaces in the primary and permanent dentitions. The carious process involves interactions between the biofilm formed on the tooth surface, sugars, salivary and genetic factors. Based on more than 100 years of research, there is unequivocal evidence that dietary fermentable carbohydrates (sugars and starch) play a key role in caries initiation and progression. In this context, sucrose deserves special attention; apart from being rapidly converted into acids it is also synthesized into extracellular glucans, fructans and intracellular storage compounds. According to the ecological plaque hypothesis, it is generally accepted that sucrose exposure is fueling and driving the stable and diverse symbiotic oral biofilm to a dysbiotic form with a reduced diversity and overgrowth of acidogenic and acid-tolerating species. Such typical bacterial profiles have demonstrated in subjects with different stages of caries in cross-sectional settings but the timing associated with a sugar provocations is less known. Moreover, the use of probiotic bacteria in adjunct to regular oral care to support biofilm diversity and prevent dental caries has gained momentum in recent years. It has been demonstrated that probiotic supplements can increase salivary pH, and reduce the counts of salivary S. mutans, thereby exert a stabilizing effect on the oral microbiota. In this context, it is of interest to explore whether or not the use of beneficial bacteria can counteract a sugar-driven shift in the salivary microbiota. Another question of interest is to study if the oral biofilm has a colonization memory similar to that of the gastro-intestinal tract and the suggested study design could possibly enlighten this area of research.

Efficacy of Sealing Molars: Split-mouth Randomized Clinical Trial

The sealing of fossae and fissures is an effective procedure in preventing occlusal caries lesions. However, there are gaps regarding its efficacy in the treatment of initial enamel lesions. In addition, there are no studies in the literature that have compared the longevity of sealings performed with the different sealants available in the market. Thus, the objective of this study is to evaluate the efficacy of fossae and fissures sealings performed with a low-cost resinous sealant in occlusal lesions in enamel in permanent and deciduous molars. This is a multicenter clinical study of non-inferiority, randomized, controlled, double blind (patient and operator) with 60 deciduous molars and 340 permanent molars of children 4 and 9 years of age. The sample unit will be the tooth, which will be randomized into two groups using a distributed randomization list in mixed envelopes that will be open only at the time of the procedure. The teeth allocated in the test group will be treated with the sealant preventâ; Those allocated in the control group will employ the Fluroshieldâ sealant. In both groups the procedure will follow the manufacturer's standards. The efficacy of the sealant will be evaluated by means of clinical and radiographic control at 6, 12 and 18 months after the procedure. Secondary outcomes, such as retention, cost, acceptability and quality of life, will also be evaluated.

Is Xylitol Toothpaste Effective in Preventing Tooth Decay?

The study will identify children at high caries risk and then advise/instruct their parents/caregivers in practicing evidence-based risk-based at home preventive measures for their infants with daily use of xylitol or fluoride toothpaste. This study plan to invite the children aged 12-15 months old with high caries risk to do the clinical trial. Every infants will be randomly allocated into two groups. Participants in the test group will be asked to use xylitol (20%) toothpaste to brush their teeth twice every day with the help of caregivers. Participants in the test control group will be asked to use fluoride (1000ppm) toothpaste to brush their teeth twice every day with the help of caregivers. The same oral health instruction and children' diet instruction will be done for every participant's caregivers. For every dental examination, clinical chatting form for the children will be collected after filling in by examiner. Questionnaire will be collected after filling in by the caregivers. And infants' plaque and saliva will be collected to detect the S. mutans level. We plan to do the dental examination three times for one infant including the first time recruiting, one year follow-up, and two year follow-up. The establishments of the good oral health-related habits will safeguard and have sustained benefits for the children. The study can provide evidence on the effectiveness of xylitol toothpaste and risk of high fluoride toothpaste among young children. In the long term, the findings of the study might serve as a foundation for establishing an effective oral health care promotion programme throughout Hong Kong and beyond. The framework, if shown to be effective, could help development of the oral health policies and promotion programmes to achieve better oral health among young children eventually.

Clinical Study Class II on Ceram.x Universal and Prime&Bond

Damage to teeth from decay or previous old silver fillings can be repaired with tooth-coloured filling materials that stick to the tooth. These materials have been around for some years and have become more sophisticated; with greater ease of placement by the dentist and better durability for the patient. The fillings are designed to be used in combination with a specific glue (adhesive) that is designed to stick to the different parts of the tooth to provide a good seal, the outer enamel and the inner dentine. This study will examine the performance of a state-of-the-art modern tooth coloured filling material (Ceram X) in combination with an existing adhesive (control adhesive) and a new adhesive (Prime & Bond Universal) used in two different techniques; both of which are known to work but one is easier to apply. This results in three treatment groups. At the start of the study, the test material Prime&Bond Universal is CE-marked, as are all other medical devices used. Thus, this study is not conducted to meet any regulatory requirements. The rationale of this study is the extension of knowledge primarily concerning the clinical performance of Prime&Bond Universal in molars. Two investigators (to be confirmed) will place a minimum of 25 restorations per group (75 restorations in total) to assess the performance of the materials in a comparative design. The study restorations will be monitored for a period of 18 months (with the option to extend the evaluation period to 48 months). After placement of restorations under controlled clinical conditions, the primary objective of the study is the determination of post-operative sensitivity and pulp vitality, marginal adaptation and staining of margins of the restorations. In addition, fracture of material and retention, recurrent caries, occlusal contour and wear, approximal anatomical form will be determined as well as the failure rate as defined by the ADA.

Improved Oral Health and Dental Care in Children With Congenital Heart Disease

Background: Congenital heart disease (CHD) is one of the most common congenital anomalies in children. As the risk for endocarditis following bacteraemia is more common during daily oral hygiene routines, such as tooth brushing, than during dental treatment, the maintenance of optimal oral health in children with CHD may be considered of outmost importance. Children with CHD have a higher caries prevalence compared to healthy controls. Aim: The primary aim of the study is to explore if an educational intervention including information, counselling and support provided at early stage to families affected by major CHD, or CHD combined with a syndrome, can increase the awareness of the importance of maintaining of good oral health, and avoid the development of poor oral health including dental caries, leading to less dental anxiety and a higher oral heath related quality of life. The secondary aim is to elucidate factors associated with the development of poor oral health and/or orofacial dysfunction as well as family attitudes and needs of support. Hypothesis: Early information, counselling and support will lead to a) increased awareness of the importance to maintaining good oral health, b) prevent the development of poor oral health and dental caries, c) lead to less dental fear, and d) lead to higher oral heath related quality of life. Study design: Randomized educational intervention trial. Study population: Children born in Finland and under 12 months of age in 1.7.2017-31.12.2021 with, a) major CHD and potentially included in the criteria of endocarditis prophylaxis, or b) with a major CHD combined with a chromosomal syndrome, will be offered to participate in the study. Patients will be recruited until 200 patients are obtained at the Helsinki University Children's Hospital. A control group consisting of approximately 100 healthy children will also be recruited at birth. Main outcomes: Dental caries, dental anxiety, oral health related quality of life, and awareness of importance to maintain and behaviour to maintain good oral health. Significance: Better information to patients leads to better possibility to achieve good oral health. Better oral health leads to 1) less dental procedures and thereby less dental anxiety, 2) less dental procedures under general anaesthesia, which may potentially be a risk procedure for the child with CHD, and 3) better oral health related quality of life.

Clinical Evaluation of Kerr SonicFill™ 2 vs 3M ESPE Filtek™ Supreme Ultra Universal Restorative

The purpose of this study is to compare esthetic, functional and biological properties of two restoration materials used to fill cavities. One material is called "Filtek™ Supreme" which is a traditional tooth colored resin composite that is placed in the cavity in layers and hardened with UV light. The second material is called "SonicFill™ 2," which is a bulk fill composite that uses an ultrasonic hand piece to change the material from a solid into a liquid in order to place it into the cavity. This material can be placed in the cavity in 1 layer, and is hardened using UV light. Both materials have been FDA approved as non-significant risk devices for filling cavities. In each subject, one tooth with a cavity will be randomly selected to receive one filling material, and a second tooth with a cavity will be randomly selected to receive the second material. The fillings will be observed over a two year period to determine clinical acceptability.

Effectiveness of ICCMS in Reducing the Incidence of Dental Caries in Children

The aim of the present study is to evaluate the effectiveness of using the ICCMS (International Caries Classification And Management System)in reducing caries lesions incidence compared to a control group that use different criteria as a not systematic and standardized prevention strategy. The study will be performed among children attending to the social project of Social Service of Commerce (SESC), Sao Paulo. The sample will be composed of 460 children aging between 7 to 12 years old registered in CURUMIM Program from eight dental centers of SESC. A randomized controlled study with parallel group will be conducted. The centers will be randomized between the 2 strategies, defining 2 groups with 4 centers each. The experimental group that will follow the criteria defined by the ICCMS will evaluate clinical and behavioral variables, it will define: evaluation of the caries risk of the patient, evaluation of the intraoral risk, diagnosis of the caries lesion and its respective activity, plan decision individualized treatment for the patient and indication of recall interval according to the risk of caries. In the control group, children need will be solved according to rthe routinely dental practices in the center, but the determination of the child's general and intraoral risk of developing new caries lesions will not be performed nor the scheduling of specific recall intervals according to the risk.
