Evaluation of the efficacy of a commercially available regimen vs brushing alone on established plaque and gingivitis on adolescents: Study protocol for a randomized, controlled, blind clinical trial.

BACKGROUND: Dental biofilm accumulation and poor personal oral hygiene are known major risk factors for gingivitis and halitosis. However, it is not clear how studies compare the effectiveness of hygiene regimens, associated with outcomes centered on patients. METHODS: A randomized, blind, controlled clinical trial involving 58 participants aged from 12 to 17 years, who search the Department of Pediatric Dentistry of Universidade Metropolitana de Santos, will be conducted. Immediately, the volunteers will be inserted into Group 1 (commercially available hygiene regimen) or Group 2 (tooth brushing alone). In Group 1, participants will receive Colgate Total 12 toothpastes, Plax mouthwashes and Colgate Ultrasoft toothbrushes, while Group 2 will use Colgate Cavity Protection toothpastes and Colgate Ultrasoft toothbrushes. The interventions will be conducted in the periods of 1, 3, and 6 months after the baseline, when the evaluations will also be performed. Biofilm and halitosis indexes will be evaluated. Data regarding discomfort, satisfaction and the socioeconomic/individual characteristics will also be computed. DISCUSSION: Although toothbrushing has shown positive effects in decreasing biofilm and in gingival health, there is no comparison in the literature of different brushing regimens with halitosis measurement in adolescents. In addition, the effectiveness of these protocols would be confirmed from the acceptability of the volunteers.

Temporomandibular disorder and headache in university professors.

[Purpose] Temporomandibular disorder is a condition with a multifactor etiology that involves the temporomandibular joint, bones, surrounding muscles and facial pain is the most common symptom. This study evaluated the possible association between headache and temporomandibular disorder in university professors. [Participants and Methods] Twenty-seven professors were recruited and answered the Axis II of the Research Diagnostic Criteria for Temporomandibular Disorders for the evaluation and diagnosis of temporomandibular disorder and filled out a "Headache Diary" proposed by the American Headache Society. [Results] The university professors showed headache and temporomandibular disorder, but no association was found between the two conditions. Comparing the gender, the males were most frequently affected, but females had more intensity of signs and symptoms. There is a lack of data on the population addressed in the present study. [Conclusion] Indeed, this was the first such study developed with university professors. It is of considerable importance to develop further studies to investigate the possible association between headache and temporomandibular disorder.

Evaluation of primary headache associated with temporomandibular dysfunction in adolescents from Santos, SP, Brazil: an observational study.

[Purpose] Evaluate the association of primary headache and Temporomandibular Dysfunction in healthy adolescents from the Santos, SP, Brazil. [Participants and Methods] A total of 208 adolescents, aged 11 to 16 years old were randomly selected at the dentistry clinic at Universidade Metropolitana de Santos. For that, the Fonseca Anamnestic Index was applied, including information such as: limitation when opening the mouth and moving the jaw, headaches, pain in the temporomandibular joint, noises in the temporomandibular joint, and the habit of tightening or grinding the teeth. The data were submitted to descriptive statistical analysis and the χ2 test and Fisher's exact test were used to evaluate the association of categorical variables. [Results] The results were 63% of male participants, and 61% of female participants had Temporomandibular Dysfunction. In both genders headache was associated with the presence of Temporomandibular Dysfunction, with 93 participants with light headache and 39 with moderate headache. [Conclusion] There was an association between headache and the presence of Temporomandibular Dysfunction, and the percentage of affected males was slightly higher among this association. In the sample of adolescents who presented Temporomandibular Dysfunction, moderate headache was the main reported symptom of both genders.

The impact of photobiomodulation on osteoblast-like cell: a review.

In this study, we present a review of the literature on the impact of photobiomodulation on osteoblast-like cell culture. Searches were performed in the PubMed/MEDLINE (Medical Literature Analysis and Retrieval System Online), SCOPUS, and SPIE digital library databases for original articles regarding the effects of LLLT on osteoblast-like cells in experimental models using LLLT published in English from the last 20 years. The search identified 1439 studies. After the analysis of the abstracts, 1409 studies were excluded and 30 studies were then selected for the full-text analysis, 8 of which were excluded. Thus, 22 studies were included for a critical evaluation of the impact of photobiomodulation on osteoblast-like cell culture. The cell lineages studied were primary rat, primary human, saos-2, Osteo-1, MC3T3, MG63, and OFCOL II. Moreover, a wide variety of experimental models were used to experimentally analyze the impact of photobiomodulation, the most common of which were alkaline phosphatase, MTT, and cell count. This review suggests that osteoblastic-like cells are susceptible to photobiomodulation but that most of the light parameters varied by different authors have little to no influence on proliferation but very high levels of irradiance have demonstrated deleterious effects on proliferation, highlighting the bi-phasic effect of photobiomodulation.

Maxillofacial Changes in Melnick-Needles Syndrome.

Background. Melnick-Needles Syndrome is rare congenital hereditary skeletal dysplasia caused by mutations in the FLNA gene, which codifies the protein filamin A. This condition leads to serious skeletal abnormalities, including the stomatognathic region. Case Presentation. This paper describes the case of a 13-year-old girl diagnosed with Melnick-Needles Syndrome presenting with different forms of skeletal dysplasia, such as cranial hyperostosis, short upper limbs, bowed long bones, metaphyseal thickening, genu valgum (knock-knee), shortened distal phalanges, narrow pelvis and shoulders, rib tapering and irregularities, elongation of the vertebrae, kyphoscoliosis, micrognathia, hypoplastic coronoid processes of the mandible, left stylohyoid ligament suggesting ossification, and dental development anomalies. Conclusion. Knowledge of this rare syndrome on the part of dentists is important due to the fact that this condition involves severe abnormalities of the stomatognathic system that cause an impact on the development of the entire face as well as functional and esthetic impairments.

Estudo de anormalidades dentárias de desenvolvimento em pacientes em tratamento ortodôntico / Study of development dental abnormalities in orthodontic patients

Introdução - As estruturas do complexo maxilo-mandibular, durante o seu desenvolvimento, ficam sujeitas a sofrerem distúrbios causados por fatores ambientais, idiopáticos ou hereditários, resultando assim, em distúrbios de desenvolvimento dentário. Estas anormalidades possuem alto índice de prevalência na população em geral, e na maior parte dos trabalhos são estudadas separadamente. O presente trabalho teve o propósito de estudar a prevalência de anormalidades de desenvolvimento em pacientes em tratamento ortodôntico. Material e Método - Foram analisadas radiografias panorâmicas de 66 pacientes, sendo 39 do sexo feminino e 27 do masculino, com média de idade de 16, 16 anos, que se submeteram a tratamento ortodôntico. Resultados - Foram diagnosticadas 273 alterações e apenas 5 radiografias não apresentaram nenhuma anormalidades, as alterações mais prevalentes foram giroversão com 75,7%, retidos/impactados com 56% e agenesia com 27,2%. Conclusões - As anormalidades de desenvolvimento são alterações frequentes dos maxilares e podem ocasionar distúrbios estéticos e funcionais levando o seu portador a procurar tratamento ortodôntico
