Is the Erich arch bar the best intermaxillary fixation method in maxillofacial fractures? : a systematic review

Background: Intermaxillary fixation is used to achieve proper occlusion during and after oral and maxillofacial fracture surgery. The aim of this systematic review was to compare Erich arch bar fixation with other intermaxillary fixation methods in terms of the operating time, safety during installation, oral health maintenance and occlusal stability. Material and Methods: An electronic online search was conducted of the Scirus, PubMed, Ovid, Cochrane Library and VHL databases. A clinical trial dating from the inception of the data bases until August 2013 was selected. Studies that compared Erich arch bars with other intermaxillary fixation methods in patients older than 18 years-old were included. The studies were assessed by two independent reviewers. The methodological quality of each article was analyzed. Results: Nine hundred and twenty-five manuscripts were found. Seven relevant articles were analyzed in this review. The risk of bias was considered moderate for four studies and high for three clinical trials. Conclusions: There is not enough evidence to conclude that the Erich arch bar is the best intermaxillary fixation method in cases of oral and maxillofacial fracture

Periodontal disease, peri-implant disease and levels of salivary biomarkers IL-1β, IL-10, RANK, OPG, MMP-2, TGF-β and TNF-α: follow-up over 5 years

Objective: The aim of this study was to evaluate the levels of salivary biomarkers IL-1β, IL-10, RANK, OPG, MMP-2, TG-β and TNF-α in individuals with diagnosis of peri-implant mucositis in the absence or presence of periodontal and peri-implant maintenance therapy (TMPP) over 5 years. Material and Methods: Eighty individuals diagnosed with peri-implant mucositis were divided into two groups: one group that underwent periodontal and peri-implant regularly maintenance therapy, called GTP (n=39), and a second group that received no regular maintenance GNTP (n=41). Each participant underwent a complete periodontal and peri-implant clinical examination. Collection of saliva samples and radiographic examination to evaluate peri-implant bone levels were conducted at two times: initial examination (T1) and after 5 years (T2). The salivary samples were evaluated through ELISA for the following markers: IL-1β, IL-10, RANK, OPG, MMP-2, TGF and TNF-α. Results: A higher incidence of peri-implantitis was observed in the GNTP group (43.9%) than in the GTP group (18%) (p=0.000). All individuals (n=12) who presented peri-implant mucositis and had resolution at T2 were in the GTP group. After 5 years, there was an increase in the incidence of periodontitis in the GNTP group compared to the GTP group (p=0.001). The results of the study revealed an increase in the salivary concentration of TNF-α in the GNTP group compared to the GTP group. The other salivary biomarkers that were evaluated did not show statistically significant differences between the two groups. Conclusions: The salivary concentration of TNF-α was increased in individuals with worse periodontal and peri-implant clinical condition and in those with a higher incidence of peri-implantitis, especially in the GNTP group. Longitudinal studies in larger populations are needed to confirm these findings and elucidate the role of this biomarker in peri-implant disease

Effect of Topical Application of Different Substances on Fibroplasia in Cutaneous Surgical Wounds

Background. Fibroblasts on the edges of a surgical wound are induced to synthesize collagen during the healing process which is known as fibroplasia. Objective. The aim of this study was to determine the effect of the application of different substances on fibroplasia of cutaneous surgical wounds on rats. Materials and Methods. 48 Wistar rats were divided into three groups. A surgical wound 1 cm in diameter and 1  mm in depth was created on the dorsum of each animal. The surgical wounds were submitted to the topical application of an alcoholic extract of 30% propolis, 70% alcohol, or 0.001% dexamethasone in a cream base every 12 hours. The animals were sacrificed three, seven, 14, and 28 days postoperatively. The specimens were histologically processed and stained with Masson's trichrome. The assessment of fibroplasia was performed using a scoring system: (1) 5 to 25% collagen deposition; (2) 26 to 50% collagen deposition; (3) 51 to 75% collagen deposition; (4) more than 75% collagen deposition. Results. There were statistically significant differences in collagen deposition between the substances at all postoperative evaluation times. Conclusion. Propolis and alcohol promoted greater collagen deposition in surgical wounds than dexamethasone

Cross-cultural adaptation of the Brazilian version of the Dentine Hypersensitivity Experience Questionnaire

Abstract The dentine hypersensitivity (DH) is able to impair the oral health related quality of life (OHRQoL). However, there isn't any specific validated questionnaire to be used in Brazil. The objective was to adapt and to validate the English version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15) for use in Brazil. DHEQ-15 was cross-culturally adapted into the Brazilian-Portuguese language and then validated in a cross-sectional study with 100 participants recruited at a University clinic. Study sample comprised 2 groups: 100 individuals with DH, and 100 individuals without. The instrument was self-administered twice 7 to 10 days apart. The participants answered a global rating of oral health. The psychometric properties of the Brazilian version of DHEQ-15 were verified through internal consistency (Cronbach's α) and test-retest reliability (intraclass correlation coefficient - ICC), convergent (Spearman correlation) and discriminant (Mann-Whitney test) validity. The significance threshold was set at p<0.05. Sample comprised 69 men and 131 women, of mean age 30.4y. The Brazilian DHEQ-15 demonstrated very good internal consistency (α = 0.945). Test-retest reliability revealed excellent reproducibility (ICC = 0.959, p < 0.001). There was statistically significant correlation between the scores obtained on all DHEQ-15 domains and the global rating of oral health (p<0.001). Participants with DH scored significantly higher than those without DH (p<0.001). This study provides evidence supporting the cross-cultural validity of the Brazilian version of DHEQ-15 for use in Brazil

PRÓTESE DENTÁRIA E DISFUNÇÃO TEMPOROMANDIBULAR: UMA REVISÃO DA LITERATURA

Objetivo: O objetivo deste artigo foi realizar uma revisão de literatura para avaliar o papel da prótese dentária no tratamento das Disfunções Temporomandibulares (DTMs). Fontes dos dados: Foram consultadas as bases de dados PubMed, LILACS, SciELO, Bireme, Web of Science, Medline, ISI, Biblioteca Cochrane e BBO. Os estudos incluídos foram publicados em inglês, espanhol ou português, entre os anos 2000 e 2023. Os descritores utilizados foram: “Disfunção Temporomandibular'', ''DTM e próteses removíveis” “DTM e perda dentárias'', “DTM e má oclusão” e “Tratamento da DTM”. Os critérios de inclusão foram artigos que avaliaram a associação entre tratamento da DTM e prótese dentária. Síntese dos dados: foram selecionados 145 estudos, dos quais 42 contemplaram os critérios de seleção propostos. A prevalência das DTMs varia amplamente na literatura. Os sinais e sintomas encontrados variaram de leves à dor severa e rara. Alguns estudos relacionaram fatores oclusais, próteses antigas e mal adaptadas sugerindo sua associação com as DTMs. Entretanto, é difícil estabelecer uma relação direta visto a diversidade de metodologias empregadas. Conclusões: a relação entre prótese dentária e as DTMs é controversa. As divergências entre os critérios de diagnóstico, avaliação clínica e do tratamento das DTMs reduziram a confiança dos resultados sobre a relação do uso ou não uso das próteses como alternativas de tratamento. Desse modo, são necessários novos estudos clínicos para melhor esclarecer os mecanismos de surgimento, controle e tratamento das DTMs e definir um protocolo protético reabilitador

Radiolucent image in lower third molar: hidden caries or pre-eruptive resorption?: a case report

ABSTRACT Caries is a multifactorial disease due to the imbalance of the de/re-mineralization process. Complementary radiographic examinations are able to detect hidden caries. The purpose of this short communication was to investigate the radiolucent image suggestive of hidden caries in lower third molar. The extraction of the tooth, decalcification, inclusion and preparation were performed for histological analysis of the lesion. Histological findings revealed a pre-eruptive resorption, and the etiological factors of this coronary resorption were undefined. The professional should be aware of the occurrences of these lesions to early diagnose and propose appropriate treatment to avoid future complications to the patient
