ABSTRACT

OBJECTIVE: To determine the transmittance spectrum of primary dressings commonly used in the treatment of cutaneous wounds to verify if there is a real need to remove them during photobiomodulation. METHODS: Spectroscopic analysis was performed on 17 dressings using a spectrophotometer (USB 2000+; OceanOptics, Delray Beach, Florida). A piece of each dressing was inserted into a quartz cuvette; the reflection from the slide walls was corrected for using a 0.9% saline solution to completely fill the cuvette (baseline). The transmittance of each dressing was measured between 350 and 950 nm, and a transmittance table was created based on the main wavelengths used in photobiomodulation. RESULTS: Six dressings (Supriderme, Membracel, Cuticell Contact, UrgoTul, Tegaderm, and Opsite Flexigrid) have a transmittance greater than 50% in most of the spectral range and therefore may remain on wounds during irradiation. CONCLUSIONS: It may not always be necessary to remove a primary dressing when lasers or LED lights are used to treat wounds. It is the authors' hope that the results of this article will increase the effectiveness of both photobiomodulation and primary dressings and reduce patient discomfort as well as the cost of primary dressings via a reduction in unnecessary dressing changes.

ABSTRACT

INTRODUCTION: Epidemiological data show that the signs and symptoms of temporomandibular disorder (TMD) start becoming apparent from 6 years of age, and during adolescence these signs and symptoms are similar to those of adults. The present study aims to estimate the direct costs for treatment of chronic muscle pain with photobiomodulation therapy, occlusal splint and placebo in patients with TMD; to evaluate the effectiveness of photobiomodulation therapy and occlusal splint for treatment of muscle pain in patients with TMD; to analyse the cost-effectiveness of the two proposed treatments for pain; and to describe and compare the results of the analyses of these treatments. METHODS AND ANALYSIS: This is a prospective trial of clinical and economic analyses that will include 135 patientswith TMD aged between 15 years and 25 years, randomly assigned to a treatment group: G1 (photobiomodulation), G2 (occlusal splint) and G3 (placebo). The analyses will be based on the cost of each treatment during the 12-month period. The outcome of the analysis of effectiveness will be pain, measured periodically by means of clinical examination of Research Diagnostic Criteria for Temporomandibular Disorders. The cost-effectiveness ratio will be calculated using, as end points, pain and the ratio of the differences in costs between the groups studied. The evaluation of the impact of the treatment on quality of life will be determined by applying the adapted EuroQol-5D. ETHICS AND DISSEMINATION: This protocol has been ethically approved by the local medical ethical committee, protocol number 2.014.339. Results will be submitted to international peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER: NCT03096301.

ABSTRACT

BACKGROUND: Temporomandibular disorder (TMD) is described as a subgroup of orofacial pain with a set of signs and symptoms that involve the temporomandibular joint, masticatory muscles, ears, and neck. TMD can occur unilaterally or bilaterally and approximately 70% of the population is affected with at least one sign. The disorder progresses with orofacial pain, muscle pain involving the masticatory and cervical muscles, joint noises (clicks and pops), joint block, mandibular dysfunction, and headache. The etiology can be abnormal occlusion and/or posture, trauma involving local tissues, repetitive microtrauma, parafunctional habits, and an increase in emotional stress. Studies have demonstrated that phototherapy is an efficient option for the treatment of TMD, leading to improvements in pain and orofacial function. METHODS: The aim of the proposed study is to compare the effects of two sources of photobiomodulation in individuals with TMD. A randomized, controlled, double-blind, clinical trial is proposed, which will involve 80 individuals aged 18-65 years allocated to either a laser group or light-emitting diode (LED) group submitted to 12 sessions of phototherapy. The Research Diagnostic Criteria for TMDs will be used to evaluate all participants. Pain will be measured using the visual analog scale and maximum vertical mandibular movement will be determined with the aid of digital calipers. DISCUSSION: This study compares the effects of two modalities of laser therapy on the pain and orofacial function of patients with TMD dysfunction. Photobiomodulation and LED therapy are treatment options for reducing the inflammatory process and pain as well as inducing the regeneration of the target tissue.

ABSTRACT

OBJECTIVES:: To evaluate the colorimetric change in incisors and canines of adolescents aged 12 to 20 years submitted to at-home whitening and to evaluate satisfaction, sensitivity and discomfort during the procedures through a questionnaire. METHOD:: Thirty adolescents were randomly assigned to the following groups: 1) 6.0% hydrogen peroxide (White Class with calcium - FGM); 2) 7.5% hydrogen peroxide (White Class with calcium - FGM); 3) 10% hydrogen peroxide (Oral B 3D White - Oral-B); 4) Control group - placebo. Assessments were performed prior to treatment as well as at 7, 30, 180 and 360 days after treatment. Friedman's ANOVA was used to analyze color. The Kruskal-Wallis test followed by Dunn's post hoc test was used to compare the groups at the different evaluation times. Answers on the questionnaires were ranked, and non-parametrical tests were employed. The groups were compared in each period using the Kruskal-Wallis test followed by the Student-Newman-Keuls test. Categorical data were analyzed using Fisher's exact test, and the Wilcoxon test was used for the analysis of different periods. P-values were corrected using the Hyan-Holm step-down Bonferroni procedure. Clinicaltrials.gov: NCT01998386. RESULTS:: Similar results were obtained one month after treatment with both tooth whitening gels and whitening strips. Patients were partially satisfied with the treatment after the first and second weeks and would recommend it. All products demonstrated color stability after 12 months of follow-up. CONCLUSIONS:: The bleaching procedure was efficient, and the patients could perceive its result. Further investigations are needed to determine the effects of bleaching on young teeth.

ABSTRACT

BACKGROUND: The elimination of pathogenic microorganisms from the root canal system is one of the major steps required for successful endodontic treatment. The aim of the proposed study is to conduct a randomized, controlled, clinical trial for the clinical and radiographic evaluation of the effectiveness of photodynamic therapy during the endodontic treatment of primary teeth. METHODS: Thirty primary anterior teeth in children aged 3 to 6 years old will be randomly divided into 2 groups: a control group, which will receive conventional treatment, and an experimental group, which will be subjected to photodynamic therapy. Microbiological evaluations will be performed before and after endodontic treatment. Moreover, clinical and radiographic evaluations will be performed on the day of treatment as well as 1, 3 and 6 months after treatment. Comparisons will be made of the two study groups. The data will be tabulated and presented in a descriptive, analytical fashion. Depending on the distribution (normal or non-normal), either the t test, ANOVA or the Mann-Whitney test will be used for analysis of the variables. The Wilcoxon test will be used for comparisons before and after treatment. P values<0.05 (95% significance level) will be considered indicative of statistically significant differences. DISCUSSION: As successful endodontic treatment is directly related to intra-canal bacterial disinfection and considering the difficult task of endodontic treatment in primary teeth, often due to difficulties in controlling young children, the internal anatomy of root canals and root resorption, the alternative of using PDT is a painless,easy-to-administer method that does not lead to microbial resistance and can assist in the achievement of successful endodontic treatment in primary teeth by eliminating the pain children can experience due to retreatment as well as premature tooth loss. TRIAL REGISTRATION: The protocol for this study was registered with Clinical Trials number NCT02485210 on 30 july 2015.

ABSTRACT

[Purpose] The aim of the present study was to evaluate the effect of a biteplate on the cranio-cervical posture of children with bruxism. [Subjects and Methods] Twelve male and female children aged six to 10 years with a diagnosis of bruxism participated in this study. The children used a biteplate during sleep for 30 days and were submitted to three postural evaluations: initial, immediately following placement of the biteplate, and at the end of treatment. Posture analysis was performed with the aid of the Alcimagem(®) 2.1 program. Data analysis (IBM SPSS Statistics 2.0) involved descriptive statistics and the Student's t-test. [Results] A statistically significant difference was found between the initial cranio-cervical angle and the angle immediately following placement of the biteplate. However, no statistically significant difference was found between the initial angle and the angle after one month of biteplate usage. [Conclusion] No significant change in the cranio-cervical posture of the children was found one month of biteplate usage. However, a reduction occurred in the cranio-cervical angle when the biteplate was in position.

ABSTRACT

Temporomandibular disorders (TMD) is a term applied to functional changes of the temporomandibular joint (TMJ) and associated structures of mastication. Aim: To investigate the correlation between body mass index (BMI) and TMD in children. Methods: 70 children between 6 and 14 years enrolled in the Rogationist Benevolent Institute of charity in the city of São Paulo (Brazil) underwent clinical examination by one calibrated examiner for the use of Research Diagnostic Criteria for TMD. Weight and height were determined by anthropometric assessment for the diagnosis of nutritional status, and BMI was calculated by dividing weight in kilograms by height in meters squared (kg/m2). Descriptive analysis (mean and standard deviation) was used to characterize the sample. ANOVA complemented by the Least Significant Difference test was used to compare the mean anthropometric measurements between the genders and the groups with and without TMD. The significance level was set at 0.05. Results: We found a significantly high prevalence of TMD, as well as a significant association between TMD light and low body weight. Conclusions: The results show a high prevalence of TMD and a slight association between TMD and children with low body weight.

ABSTRACT

The development of conservative techniques for the removal of carious tissue and the improvement of dental restoration materials allow better preservation of the dental structure. Chemomechanical caries removal is a conservative and atraumatic alternative. Papacárie is a papain-based material developed to act only on the carious dentin, allowing its easy removal with a blunt curette. This study aims to present a clinical case of aesthetic restoration of both upper deciduous central incisors after the removal of carious tissue with Papacárie.
