Filter by:A cross- sectional observational study which will investigate whether data of past caries experience of the primary molars of 6-9 years old children can serve as an indicator for caries development in first permanent molars.as the first permanent molars is selected to represent the future caries status of the permanent dentition.
Effect of CPP-ACP pastes with/without Fluoride on White spot lesion progression, salivary pH and fluoride release in high caries risk Patients, over 3 month period using VistaCam, Digital pH meter and Selective ion electrode.
The hypothesis is that Addition of copper or zinc nanoparticles to a dental adhesive confers antimicrobial and enzymatic degradation-resistant properties, retaining its adhesion mechanical properties and biocompatibility. To corroborate this hypothesis two groups of a dental adhesive doped with copper or zinc nanoparticles should be develop with a respective structural characterization by SEM-EDX, AFM and FTIR. This should be followed by a test of the antimicrobial activity of adhesive and a study of the influence of adhesive nanocomposites on matrix metalloproteases levels and/or activity in vitro to determine some concentrations more relevant. These would proceed to next stage. With the selected adhesive doped concentrations should be evaluate mechanical properties of doped adhesives and assess the biocompatibility by assays in primary cultured gingival fibroblast and cells type odontoblasts. Finally, once the concentration of either Cu- or Zn-doped adhesives is known, these will be evaluated with a clinical design phase in an in vivo model to study antimicrobial properties, matrix metaloproteases levels and/or activity. We will also study biocompatibility of adhesive nanocomposites and mechanical properties to corroborate the in vitro and ex vivo properties determined. There are results using copper nanoparticle on biomaterials that corroborates some properties such as antimicrobial activity against various species and copper release. All the evidence suggests that at low concentrations of copper nanoparticles, there are no significant effects on mechanical properties but with added antibacterial properties on the adhesive
Evaluate the effect of propolis extract mouthwash and pomegranate extract mouthwash on taste alteration, salivary pH and antibacterial activity against streptococcus mutans in high caries risk patients.
Scientific background(Statement of the problem): Dental caries is a disease that occurs through complex interaction of four major factors: the host, acidogenic bacteria, fermentable carbohydrates and time. There are many factors which contribute to dental caries incidence but do not seen in clinical examination. Those things are considered as dental caries risk factors, such as socioeconomic, attitudes, knowledge and behavior toward oral health. These risk factors play an important role in incidence of the disease, significantly associated with disease progression . The traditional "drill and fill "concept has served to restore function and esthetics but it has failed to prevent development of new carious lesions. In recent years; better understanding of nature of carious process has changed this operative treatment concept to non destructive risk -based caries management. Caries risk assessment is a procedure used to predict dental caries development before clinical onset of disease, through assessing risk factors contributing to progress of dental caries and let oral health care professionals to be more active in identifying and referring high risk patients for proper treatment and required prevention. Rationale for carrying out this study : Many studies have measured dentists' knowledge toward caries risk assessment all over the world, but no studies have examined Egyptian Dentists' subjective ratings of the importance of specific caries risk factors or tested whether they use this information in treatment planning. So the aim of this study to assess knowledge, attitude and practice toward caries risk assessment and management among group of dental interns in Egypt. Benefits to the Dental interns: - Challenge the knowledge of the intern dentists regarding caries risk assessment. - Encourage the concept of minimally invasive dentistry to be applied in clinical practice. - Accurate caries risk assessment in patients can guide clinician to give attention of their resources to high risk patients. Benefits to the patients: - Will benefit from proper knowledge, attitude and practice of dentists, thus proper treatment will be provided. - Behavioral modification of patients toward oral hygiene practices. - Reducing patient risk of developing advanced disease and may even arrest disease process. Benefits to the Community: -Imparting knowledge of Caries risk assessment to dentists will benefit their patients especially high-caries risk patients by giving proper preventive interventions that help to reduce the expected elevated incidence and severity of caries in the future, therefore the whole community will benefit.
the effect of mother prenatal care on the teeth of the newborn children, if it affect the tooth structure or not
To compare the effect of a natural herbal licorice containing preventive measure alternative to chlorohexidine preventive measure to decrease the effect of streptococcus mutans.
The aim of this study is to assess the prevalence of dental caries using CAST index among a group of Egyptian children in primary dentition stage. Egyptian children aging from three to six years old attending the Outpatients' Clinic of both of Pediatric Dentistry Department, Faculty of Dentistry, Misr University for Science and Technology and the Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Cairo University will be examined using Caries Assessment Spectrum and Treatment
the objective of this study is to compare the caries index between Sudanese and Egyptian adult Population in patients with different diet habits and different oral hygiene state in range of (18-40) years old
Black stains (BS) are type of extrinsic discoloration of the tooth. It's characterized as dark lines or an incomplete coalescence of dark dots found mostly on cervical third of the crown. Most studies worldwide found that children with the black stained teeth have low caries prevalence. A study on Brazilian population also suggested that black stains might be protective factor against development of dental caries. A study reported that chromogenic bacteria were proposed as etiological factor in production of black stains.The most common microbiological composition of BS was found to be Actinomycetes. Dental examination and saliva samples collection will be done for black stained teeth children of outpatient clinic of Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Cairo University. This research adopts null hypothesis; it assumes that there is no effect on dental caries experience in children with black stained teeth.
