Filter by:Early childhood caries (ECC) is a potentially painful and debilitating disease, which represents a significant public health problem among young children. There are profound disparities in ECC experiences such that children from minority and low-income families suffer a disproportionate share of the disease burden. The likelihood of parents of high-ECC risk young children seeking prevention in dental facilities is low; therefore, there is a need to increase preventive dental opportunities where these children already seek health care services. In particular, there is an urgent need to develop and evaluate ECC behavioral interventions for use in public health settings attended by high-risk children. Many authors recommend early implementation of oral health education as one means of preventing ECC. However, major issues discussed in the oral health promotion literature involve a lack of effectiveness among programs based on education alone, as well as a lack of high quality preventive interventions using evidence-based psychological and behavioral strategies. Our research team has been the first to introduce to the ECC prevention arena the self-determination theory (SDT) of motivation, internalization, and healthy functioning, proven effective in promoting positive behavioral changes in several other fields, including oral health care. The investigators have demonstrated that SDT has great promise as a motivational approach by providing evidence, based on results from our R21 (R21-DE016483) study, of the effectiveness of SDT in changing several desirable oral health behaviors for ECC prevention. Building upon the rigor of our previous experience and formative research work in the past several years, the investigators propose a Stage II NIH Model research project that will compare the efficacy of autonomy-supportive videotaped oral health messages framed by SDT to more traditional neutral videotaped messages. The investigators intend to recruit 634 pregnant mothers enrolled in Iowa Women, Infants and Children (WIC) Supplemental Nutrition Programs and follow them until their future child is 36 months old. The primary outcome of interest will be children's caries status. Secondary outcomes will be changes in children's oral health behaviors conducive to better oral hygiene and dietary habits, as well as lower levels of dental plaque and mutans streptococci.
This study aims to investigate consecutive biological changes in proximal contact tightness using digital force gauge and evaluate proximal contact location using cone beam computed tomography between class II direct composite restorations and adjacent teeth after using sectional matrix system and with different contact forming instruments.
Type of study: Randomized Clinical trial To compare post-restorative sensitivity between titania nanoparticle reinforced bonding agent and bonding agent without nanoparticles in posterior composite restorations. Participants aged 18 years and above with Class-I and Class-II Carious lesions are allocated in two groups. Group A will undergo composite restoration with Nanoparticles incorporated in bonding agent. Group B will undergo restoration without nanoparticles in bonding agent.
Class II caries affects proximal surfaces of premolars and maintain their anatomical proximal contact of tooth, is important to avoid food impaction in the interdental area for protection of periodontium and occurrence of secondary carious lesion.Different types of Matrix band system are used to restore tooth cavities with missing proximal walls, including flat or pre-contoured bands, retainer-fixed circumferential systems, and sectional matrices, and either metal or plastic matrices which produces good contours and contacts for use with amalgam and can also be employed for insertion of composite resin.This study aimed at assessing the influence of different matricing techniques :either sectional matrix or circumferential matrix and the influence of operator experience on reproduction of optimum proximal contacts for posterior proximal resin composite restorations.
• The evolution of conservative dentistry that adopts the preservation of tooth structure and affected dentin that can remineralize and save the pulp from exposure, in addition to pain and fear that companies' traditional caries removal methods had led to the development of chemomechanical caries removal materials (CMCR). The old generations of CMCR agents were NaOcl-based materials which have disadvantages such as odor taste, Unpleasant smell, high cost, Limited shelf life, and time consumption. • All of the reasons described led to a new generation of CMCR materials depending on Enzymes such as Papain. Brix3000 and Papacarie duo are Papain-based materials with promising effects in caries removal and fewer disadvantages. Selecti-solve is a dental gel whose active ingredient is papain enzyme, it removes dental caries without the need for anesthesia and is selective for the infected dentin layer only which avoids the unnecessary loss of dentin, enamel breaking, and pulp exposure. This study aims to evaluate the efficacy of Papain-based materials compared to old NAOcl-Based materials in reducing the disadvantages of CMCR agents.
The objectives were to evaluate the antibacterial effect of self-etching adhesives on carious dentin and the clinical results of restorations in a randomized controlled clinical trial. 104 carious deciduous molars (n=92) were randomly allocated to receive one of the self-etching adhesives: Clearfil SE Bond - control (CB - n =53) or Clearfil SE Protect containing MDPB (CP - n=51) after caries removal selective. Clinical, radiographic, photographic and plaster model assessments (n=53 deciduous molars, CB=29, CP=24) of resin restorations were performed at baseline and at 6, 12, and 24 months. Dentin samples (n=51 deciduous teeth; CB=24 and CP=27) were collected immediately after excavation of carious dentin and 3 months later, and cultured for mutans streptococci - (MS), lactobacilli (LB) and total microorganisms (TM). Data were statistically analyzed (p<0.05).
The purpose of this study is to further characterize basic pharmacokinetic (PK) parameters in healthy children to contribute to evidence for the safety of silver diamine fluoride (SDF; Advantage Arrest). Children with at least one active cavity will be treated and then have blood draws at random time points afterwards.
Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. These tissues have poor regeneration capability because of the lack of both regenerative cells and vascularization. In the complex caries progression process involving dietary sugars, bacterial metabolism and demineralization, the collagenous organic matrix becomes exposed and destroyed by resident and bacterial proteases, allowing the lesion to expand
To compare the effectiveness of the semi-annual application of 38% SDF with two post-treatment protocols in arresting dental caries in preschool children
Children from two orphanages will be examined for dental caries experience, in comparison to parented school children.
