Filter by:Introduction: Molar Incisor Hypomineralization (MIH) is a qualitative defect of enamel development that occurs in the mineralization phase. MIH affects one or more permanent molars and, occasionally, permanent incisors. The aim of the proposed study is to evaluate the clinical effect of antimicrobial photodynamic therapy (aPDT) on permanent teeth with MIH through decontamination and sensitivity control. The longevity of the restorations will also be evaluated after the deproteinization procedure. Methods and analysis: Patients 8 to 12 years of age with permanent molars will be randomly allocated to three groups. Group 1: selective chemical-mechanical removal of carious dentinal tissue around the walls of the cavity with Papacárie Duo and a curette followed by the application of aPDT and deproteinization with Papacárie Duo; Group 2: selective removal of carious dentinal tissue around the walls of the cavity with a curette, followed by the application of aPDT and deproteinization with a 5% sodium hypochlorite solution; Group 3: selective removal of carious dentinal tissue using a curette. The selected teeth must have a carious lesion in the dentin and post-eruptive enamel breakdown on one or more surfaces with an indication for clinical restorative treatment. The teeth will subsequently be restored using a mixed technique with resin-modified glass ionomer cement and bulk-fill composite resin. The data will be submitted to descriptive statistical analysis. Associations with age and sex will be tested using either the chi-squared test or Fisher's exact test. Pearson's correlation coefficients will be calculated to determine the strength of correlations between variables. Comparisons of the microbiological results (colony-forming units) will be performed using ANOVA and the Kruskal-Wallis test. Kaplan-Meier survival analysis will be performed to assess the performance of the restorations.
Photobiomodulation has been widely used as complementary treatment for dentin hypersensitivity, with reports of clinical success. However, the literature offers only one study in which photobiomodulation was used for the treatment of sensitivity in molars with molar incisor hypomineralization (MIH). The aim of the proposed study is to determine whether photobiomodulation enhances the results of treatment with glass ionomer sealant on molars with MIH that present sensitivity. Methods and analysis: The study involving 50 patients 6 to 12 years of age tha will be randomly allocated in two groups. Group 1 (control group) (n = 25): toothpaste with a concentration of fluoride, glass ionomer sealant and sham low-level laser (LLL) and Group 2 (n = 25): toothpaste with a concentration of fluoride, glass ionomer sealant and active low-level laser (LLL). The evaluations will involve MIH record, Simplified Oral Hygiene Index (OHI), Schiff Cold Air Sensitivity Scale (SCASS) and Visual analog scale (VAS) before the procedure. Immediately after the procedure hypersensitivity index (SCASS/VAS) will be register. Record of OHI and SCASS/VAS will be register 48 horas after and as well as 01 month after the procedure. It is expected that by the second consultation a decrease in sensitivity will be observed due to the treatments received in the two groups.
The second primary molar (SPM) development start at the same time as development of the first permanent molars (FPM) and permanent incisors so any systemic disturbance - causing stunted growth -occur , will result in hypo-mineralization of SPM as well as FPM and permanent incisors (Butler 1967, Weerheijm and Mejàre 2003). The literature shows no previous studies that discuss the association between hypo- mineralized second primary molar (HSPM), MIH and the stunted growth in children. aim: Estimate Prevalence of HSPM and MIH in stunted children.Evaluate the association between HSPM, MIH and the stunted growth in a group of Egyptian children. • The diagnostic criteria for MIH established based on the European Academy of Pediatric Dentistry criteria (Weerheijm and Mejàre 2003) while diagnostic criteria for HSPM was established by (Elfrink et al. 2008).
The study focuses on the analysis of enamel defects grouping together hypomineralization and hypoplasia. It focuses on 3 very characteristic enamel pathologies that are most often encountered in dental consultations: Molar Incisor Hypomineralization (MIH), dental fluorosis (FD) and amelogenesis imperfecta (AI). The research focuses on the use of a spectrophotometer for measuring tooth colors: the Zfx SpectroShade® (MHT) and its software as a means of early diagnosis of pre-eruptive enamel abnormalities. The main objective of the study is to analyze the color parameters of teeth affected with one of the 3 enamel abnormalities for use of the spectrophotometer as a non-invasive diagnostic tool for enamel defects. The secondary objective is focused on the biological, structural and physicochemical characterizations of these different enamel pathologies from extracted teeth or enamel biopsies that must be ground to achieve a restoration.
Aim of the Study Evaluate association between HSPM and MIH in Egyptian children. Record the prevalence of HSPM and MIH in Egyptian children
To investigate the efficacy of laser therapy associated with fluorotherapy in the desensibitization of hypomineralized teeth in children 8 to 12 years of age. A randomized blinded clinical trial will be conducted. The instruments used will be a questionnaire general, clinical examination, dental air syringe (evaluation of dental sensitivity) and visual analogue scale (evaluation of the magnitude of dental sensitivity). Teeth with hypomineralization molar-incisor (HMI) and the results of sensitivity and magnitude of dental pain before and after the treatments will be recorded in a clinical record. The study groups will be: treatment with laser therapy (Group 1); treatment with fluorotherapy (Group 2) and treatment with laser therapy and fluorotherapy (Group 3).
