Filter by:The objective of this research was to evaluate the clinical effect of photodynamic therapy on dentin infected by caries lesion in permanent teeth with Molar Incisor Hypomineralization (MIH). The study was composed of Groups (1 and 2). The methodology was based on the selection of patients from 6 to 12 years of age with permanent molar teeth, randomly divided. The selected teeth had deep dentin caries lesions on the occlusal surface, and sensitivity, indicated for clinical restorative treatment. Photodynamic therapy was applied with the use of low-intensity laser in permanent teeth selected for the treatment of infected dentin in G1. In this group, antimicrobial photodynamic therapy (aPDT) and atraumatic restorative treatment (ART) were made. In G2, only ART was performed. The teeth were restored with high viscosity glass ionomer cement. All patients had clinical and radiographic follow-up with a time interval of 6 and 12 months. Data were submitted to descriptive statistical analysis. For the evaluation of the association of categorical variables like age and gender, the Chi-square test and Fisher's exact test were used. To analyze the correlation between the continuous variables, the Pearson correlation test was applied. ANOVA and Kruskal-Wallis were applied for the analysis of dentin density in the radiographic images scanned and the microbiological results for colony forming units.
Vital pulp therapy (VPT) is a general term for multiple procedures (indirect pulp cap, direct pulp cap and pulpotomy) all directed toward preserving pulp vitality and enable complete root development in immature teeth. The aim of this study is to evaluate the clinical, radiographic and histologic (if any teeth later are doomed for extraction for orthodontic or other reasons) success rate of VPT on treating cariously exposed permanent teeth with developmental defects of enamel. This will be a a prospective case series study including children between 6-16 years old having tooth with enamel hypomineralization defect with deep caries, restorable teeth , and no signs of infection. The teeth will be followed up both clinically and radiographically for 1 year after treatment. It is expected that the teeth will maintain vitality with resolution of symptoms (if present) and completion of root development in immature teeth after vital pulp therapy.
Background: Nowadays an increase in the incidence of teeth affected by molar incisor hypomineralisation (MIH) has been observed. There are several treatment modalities that depend on the degree of severity of the defect, such as preventive procedures, restorative and even dental extractions. However, these changes may affect the retention and longevity of restorative materials. Therefore, the aim of this study is to evaluate the use of diode laser irradiation for the treatment of occlusal surfaces of moderate lesions in permanent first molars affected with MIH as a preventive method for dental caries and occlusal wear, besides verifying the discomfort of the treatment by patients. Methods: For this, a controlled and randomized study, with parallel groups, will be conducted comparing the treatment with diode laser and sealing with high viscosity glass ionomer cement in the teeth affected by the MIH. Participants will be assessed at baseline and after 1 week, 1, 6, 12, 18 and 24 months. As the main outcome, the presence of dentin caries lesion and /or occlusal surface wear included in the study with dentin involvement will be evaluated. A visual examination for caries detection will be done using the ICDAS, using the index based on classification in the United States Public Health Service - Modified (USPH) for evaluation of sealed teeth and impression of impacted teeth for quantitative analysis of the lesions. Other outcomes such as patient satisfaction with treatment, patient discomfort, impact on quality of life and participant perception, as well as the duration and cost of treatment, as well as their cost-efficacy, will also be evaluated. Multilevel statistical analyzes will be performed to verify the efficacy of Diode laser treatment compared to sealing, in addition to possible factors associated with this efficacy.
The main aim of this study is to investigate potential associations between maternal pre- and postnatal vitamin D level and oral health outcomes (caries and developmental defects of enamel) in their children at 7-9 years of age.
Aim: To evaluate the clinical survival of fluoride sealants applied in first permanent molars affected by Molar-Incisor Hypomineralization (MIH). Material and Methods: For this case control study, it was selected 41 first permanent molars of the 21 children aged 6-8 years. MIH was classified by one calibrated examiner (kappa 0.80) according severity of the MIH lesion (EAPD, 2003). Inclusion criteria were FPM with MIH or sound (without MIH), fully erupted, and with sealant treatment indication. The FPMs were assigned into two groups: G1 - Control group and G2 - MIH group. Both group teeth were treated with sealant application (Fluroshield, NY, USA). Clinical follow-up was performed at baseline, 1, 6, 12 and 18 months for anatomic form, marginal adaptation, retention and presence of caries, according to the United States Public Health Service USPHS-Modified by a blinded examiner (kappa 0.80). The Acturial Method was used to evaluate the survival of sealants. Statistical analysis compared the ratings of each criterion between materials using the Fisher's exact test at a level of significance of 5% (p<0.05).
The restorative management of molars with Molar-Incisor Hypomineralization (MIH) represents a challenge in the clinical practice with high failure rate. Thus, this clinical trial aimed to evaluate the clinical survival of direct composite resin restorations in first permanent molars (FPMs) that are affected by MIH, comparing two adhesive systems.
The purpose is to compare the efficacy of an intraosseous anaesthesia using a computerized system (QuickSleeper) to a conventional infiltration anesthesia. Our hypothesis is that anesthesia via QuickSleeper system can reduce pain during anesthesia and obtain a more rapid local anesthesia compared to the anesthesia via conventional technique by infiltration. Design: split-mouth design AND parallel-arm design
