Conservative approach for molar-incisor hypomineralization: a case report and 7-year follow-up.

Molar-incisor hypomineralization (MIH) can result in minor injuries or major structural loss, especially in incisors and molars. Patients with MIH seek dental treatment early, usually in childhood. Choosing the best treatment option during this stage can be a challenge. Because these patients still present a mixed dentition, the use of prosthetic appliances is not usually the best option. This case report with a 7-year follow-up presents an overview of a conservative approach for the restoration of teeth affected by MIH. A 10-year-old girl presented with permanent molars and incisors that exhibited qualitative defects of enamel characteristic of MIH. During the restoration phase, direct resin-modified glass ionomer cement (RMGIC) restorations were placed in all 4 first molars with the aid of acetate crowns, which were used to facilitate reconstruction of the tooth morphology. The maxillary incisors were previously treated by another dentist, and the mandibular incisors were treated later, since they were not the main complaint of the patient at the time. During 7 years of follow-up, the RMGIC restorations proved to be a good option, presenting greater longevity in a molar with minor structural defects and requiring repair or replacement in molars with larger structural defects. Despite some failures and the necessity for new restorations, the patient conveyed satisfaction with the treatment and reported no tooth sensitivity, and there was no recurrence of caries. During this follow-up period, the defective mandibular incisors were treated first with enamel microabrasion, which proved esthetically unsatisfactory, and then with direct composite resin veneers. The results in this patient suggest that use of RMGIC may be a feasible conservative option for tooth restoration in young patients with a mixed dentition when permanent molars exhibit extensive structural loss associated with MIH.

Association between quantitative measures obtained using fluorescence-based methods and activity status of occlusal caries lesions in primary molars.

BACKGROUND: Fluorescence-based methods (FBM) can add objectiveness to diagnosis strategy for caries. Few studies, however, have focused on the evaluation of caries activity. AIM: To evaluate the association between quantitative measures obtained with FBM, clinical parameters acquired from the patients, caries detection, and assessment of activity status in occlusal surfaces of primary molars. DESIGN: Six hundred and six teeth from 113 children (4-14 years) were evaluated. The presence of a biofilm, caries experience, and the number of active lesions were recorded. The teeth were assessed using FBM: DIAGNOdent pen (Lfpen) and Quantitative light-induced fluorescence (QLF). As reference standard, all teeth were evaluated using the ICDAS (International Caries Detection and Assessment System) associated with clinical activity assessments. Multilevel regressions compared the FBM values and evaluated the association between the FBM measures and clinical variables related to the caries activity. RESULTS: The measures from the FBM were higher in cavitated lesions. Only, ∆F values distinguished active and inactive lesions. The LFpen measures were higher in active lesions, at the cavitated threshold (56.95 ± 29.60). Following regression analyses, only the presence of visible biofilm on occlusal surfaces (adjusted prevalence ratio = 1.43) and ∆R values of the teeth (adjusted prevalence ratio = 1.02) were associated with caries activity. CONCLUSION: Some quantitative measures from FBM parameters are associated with caries activity evaluation, which is similar to the clinical evaluation of the presence of visible biofilm.

Influence of cross-infection control methods on performance of pen-type laser fluorescence in detecting occlusal caries lesions in primary teeth.

The aim of this in vitro study was to determine the influence of cross-infection control methods, as probe tip autoclaving and polyvinyl chloride (PVC) wrapping, on the performance of laser fluorescence device (DIAGNOdent pen--LFpen) on occlusal surfaces of primary molars. One experienced examiner carried out all examinations (n = 78). For the probe tip autoclaving study, 62 sites (sample A, 40 teeth) were used. The sites were assessed with LFpen using tips in six different conditions: without autoclaving and after autoclaving for 10, 20, 30, 40, and 50 cycles of 10 min. For the PVC wrapping study, we selected other 58 sites (sample B, 38 teeth). The sites were assessed with the LFpen device in two conditions: with and without PVC wrapping. The teeth were sectioned and histologically assessed for caries depth. LFpen values, sensitivity, and specificity were compared among the different conditions. The LF readings were slightly higher after successive examinations, independently of autoclaving. In both studies, no statistical differences in the sensitivity and specificity were observed for all conditions. In conclusion, probe tip autoclaving and PVC wrapping do not influence the performance of LFpen device on occlusal surfaces of primary molars.

Can the individual calibration be modified when laser fluorescence method is used for caries detection?

BACKGROUND: Individual calibration (IC) for caries detection methods based on fluorescence is time-consuming, especially for paediatric dentists, if the calibration has to be performed tooth-by-tooth. However, it is not clear how this calibration actually interfere in laser fluorescence (LF) readings. AIM: This in vivo study was to verify the influence of different modes of IC on laser fluorescence (LF) readings. DESIGN: Ninety six occlusal and 95 buccal surfaces of 1st permanent molars were examined using LF device after IC performed on control (no IC), the examined teeth, a permanent incisor, a 1st primary molar or a 2nd primary molar. All modes of IC were performed in the same child. Wilcoxon test and Bland-Altman analysis were used to compare the readings. Intraclass correlation coefficients (ICC) were calculated. RESULTS: Laser fluorescence readings without prior calibration were higher than readings performed after any mode of IC and resulted in different values of ICC. After other IC modes, the LF readings were statistically similar. CONCLUSION: The absence of IC influences LF readings and LF reproducibility, but different IC methods can be considered in clinical practice.

New proposal of silver diamine fluoride use in arresting approximal caries: study protocol for a randomized controlled trial.

BACKGROUND: Approximal surfaces are a challenge to caries lesions control. Silver diamine fluoride (SDF) is a simple,low-cost and promisor intervention for arresting caries lesions, but it has never been tested on approximal surfaces. Our aim is to evaluate the efficacy and cost-efficacy of SDF in arresting initial lesions compared to resin infiltration and exclusively flossing (control group). Our second aim is to assess discomfort and satisfaction regarding interventions. METHODS/DESIGN: This is a randomized clinical trial, double-blinded, placebo-controlled study. Children/adolescents presenting at least one approximal initial caries lesion in primary molars/permanent premolars and molars will be included. Surfaces with advanced dentine lesions identified by radiography and participants who refuse to participate or present negative behaviors will be excluded. A minimum sample size of 504 surfaces will be required for each subgroup. Individuals will be randomly allocated in three groups of interventions: SDF, resin infiltration, and control group. Depending on the allocation, the patients will receive the active treatment and respective placebo therapies. All patients will be oriented to daily flossing the included surfaces. Our primary outcome will be caries progression by clinical and radiographic examinations. Appointments will be timed and costs of materials will be considered to calculate cost-efficacy. Patient discomfort will be assessed after interventions. Parent and patient satisfaction with the treatment will be collected after treatment and in the last follow-up visit. Individuals will be assessed at 1 and 3 months after treatment to evaluate dental biofilm and at 6, 12, and 24 months to assess caries progression by visual examination and/or radiography. Multilevel analyses will be used to verify if the type of treatment influenced on the tested outcomes. Costs will be compared and analyses of cost-efficacy will be performed. Poisson analysis will test the association between intervention and reported discomfort and satisfaction. DISCUSSION: Our hypothesis is that SDF is the most cost-efficacious option from all tested interventions. If our hypothesis is confirmed, the use of SDF in private and public contexts could represent an easier and effective option in the treatment of enamel approximal caries in children/adolescents.

Custo-eficácia do uso de escova infantil com cerdas longas nas pontas associada à técnica de escovação anteroposterior comparada à escova de cerdas planas associada à técnica transversal no controle de lesões de cárie em molares permanentes em erupção - estudo clínico randomizado / Cost-efficacy of anteroposterior toothbrushing using a toothbrush with extra-long bristles in the tip vs. cross-toothbrushing using a toothbrush with bristles in the same plane- randomized and controlled clinical trial

Este estudo clínico randomizado teve por objetivo avaliar se a escovação anteroposterior com escova de cerdas longas nas pontas (modo teste) foi mais custo-eficaz do que a técnica de escovação transversal com escovas de cerdas retas (modo controle) no controle de lesões de cárie na superfície oclusal de molares permanentes em erupção. Cento e quarenta participantes (66 crianças e 74 adolescentes) foram aleatoriamente designados para os grupos teste e controle. Os participantes foram acompanhados por 24 meses. Para determinar as diferenças entre os grupos em termos de eficácia, foram utilizadas as análises por intenção de tratar (ITT) e por protocolo, além de análises de sobrevida. Foram considerados como desfecho: 1) qualquer tipo de progressão e 2) progressão para cavidade. A análise de viabilidade econômica foi determinada através do custo da escova e seu grau de deterioração. Para comparação da relação de custo-eficácia entre os grupos utilizou-se a razão de custo-eficácia incremental. O modo teste mostrou-se superior quando a progressão geral de lesões foi considerada. As análises por protocolo e de sobrevida mostraram tendências semelhantes. A análise por ITT para progressão geral das lesões, bem como todas as análises considerando a progressão ara cavidades, não mostraram diferença entre os grupos. A custo-eficácia incremental entre os modos de escovação foi superior aos valores recomendados pela Organização Mundial de Saúde para tratamentos custo-eficazes. Conclui-se que o modo teste apresenta um impacto reduzido em termos de eficácia na redução da progressão de lesões de cárie em molares em erupção comparado ao modo controle e não é mais custo-eficaz que este último a ponto de ser indicado para substituí-lo na prática clínica...

This single-blinded randomized clinical trial investigated if the anteroposterior toothbrushing using a toothbrush with extra-long bristles in the tip (test mode) was more cost-efficacious than cross-toothbrushing technique using toothbrush with bristles in the same plane (control mode) in controlling caries lesion progression on occlusal surfaces of erupting first permanent molars. One hundred and forty participants (66 children and 74 adolescents) were randomly assigned for test and control modes of toothbrushing (technique + toothbrush). They were followed-up for 24 months. For assessing differences between groups in terms of efficacy, per protocol, intention to treat (ITT) and survival analyses were used. The outcomes set were: 1) overall caries lesions progression; 2) caries lesions progression for cavity threshold. Toothbrush cost and deterioration were considered for economic feasibility. The cost-efficacy between groups was compared using the incremental cost-efficacy ratio. The test mode was superior regarding overall caries lesion progression. Per protocol and survival analyses showed similar trends. ITT analysis for the previously mentioned outcome, as well as all analyses considering progression for cavitation threshold, did not show differences between groups. Incremental cost-efficacy ratio was superior to the thresholds determined by World Health Organization for being cost-efficacious treatments. In conclusion, the test mode has reduced impact on caries lesions progression compared to the control mode and is not most cost-efficacious than that. Therefore, the replacing the control mode for the test mode in clinical practice is not recommended...
