Filter by:to remineralize the white spot caries lesions after orthodontic treatment , the investigator will use two different materials ( Clinpro tooth creme versus Gc tooth mousse) and will compare between their effects in remineralization of white spot caries lesions.
The aim of this 2-arm parallel trial was to evaluate enamel demineralization after an indirect bonding technique in comparison to a direct bonding technique group using the quantitative light-induced fluorescence method. Thirty-six patients who needed fixed orthodontic treatment were randomly separated into either the direct bonding group or the indirect bonding group. Eligibility criteria included moderate crowding in the maxillary and mandibular dental arch, good oral hygiene, absence of craniofacial anomalies, no previous orthodontic treatment and no deciduous, congenitally missing or extracted teeth. Randomization was made at the start of the study with a statistical analysis program (SAS Institute Inc., Cary, NC, USA.). For the patients in the indirect bonding group, bonding was performed with a flowable composite adhesive, while the patients in the direct bonding group received a bonding procedure with a conventional composite adhesive. Records were taken using quantitative light-induced fluorescence (QLF) with a Digital Biluminator (Inspektor Research Systems, Amsterdam, the Netherlands) in the pretreatment and posttreatment examination phases. The presence and extent of lesions on the buccal surfaces of all teeth, except the molar teeth, were assessed. The fluorescence loss, lesion area and percentage of fluorescence loss were determined using the system's software. The primary outcome of this study was evaluation of the effects of bonding techniques on white spot lesion formation by using the QLF method. Random sequence generation was performed with a computerized random 1:1 allocation using block sizes of 4. It was not possible for the clinicians and their interventions to be blocked. The patients and the specialists were blinded to the treatment groups when their treatment groups were aware.
evaluate the effect of a single application of Clinpro XT varnish on enamel demineralization adjacent to orthodontic brackets during fixed orthodontic treatment in comparison with acidulated phosphorus fluoride gel. this study is to assess the durability of the results obtained from both materials (Clinpro XT Varnish- APF Gel) this study is to determine the degree of patients' satisfaction after the use of both materials (Clinpro XT Varnish - APF Gel)
This study is a randomized controlled trial involving 118 children ages between 4 and 5 years to assess the remineralization effect of Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP) on white spot lesions in primary teeth using Quantitative Light-induced Fluorescence (QLF) system, and compare that with fluoride alone or combined use of fluoride and CPP-ACP.
Dental caries is the destruction of the tooth structure in the presence of organic acids produced by cariogenic bacteria located in the dental biofilm (Dowker et al., 1999 and Robinson et al., 2000).Tooth enamel comprises 90% substituted hydroxyapatite (Ca10 (PO4)6(OH) 2), which is subjected to consecutive cycles of demineralization and remineralization. This is an interrupted process, with periods of remineralization and demineralization occurring, depending on the state of the oral environment in terms of the prolonged accumulation and retention of bacterial plaque on the enamel surface (Aoba, 2004). Oral bacteria ferment carbohydrates to produce organic acids which lower the pH and cause the subsurface dissolution of the hydroxyapatite crystals. Under normal physiological conditions (pH7), saliva is supersaturated with calcium and phosphate ions which diffuse into the vacancies created during acid-mediated demineralization episodes (Dowker et al., 1999 and Robinson et al., 2000). The demineralization of enamel (white spot lesions) is a significant problem during and after orthodontic treatment with prevalence 71.1% and various preventive measures have been suggested to minimize the incidence (Derks et al., 2004 and Al Maaitah et al., 2011).
Orthodontic appliance causes increase in plaque accumulation, especially around brackets, wires and attachments. Advances in orthodontics in recent time have led to improved quality of appliance and treatment procedures ultimately resulting in improvised standard of patient care. These bacteria metabolize different kind of carbohydrates accumulated around orthodontic appliances and create acidic environment in the oral cavity leading to enamel demineralization around the brackets and white spot lesions. This study was carried out to evaluate and compare the efficacy of probiotic toothpaste and chlorhexidine mouthwash in patients undergoing orthodontic treatment with individuals who are not using them.
