Implication of general anaesthetic and sedation techniques in temporomandibular joint disorders – a systematic review

The purpose of this study was to conduct a systematic review of the literature on temporomandibular joint damage directly related to general anaesthesia and sedation. We searched MEDLINE, SCOPUS and the COCHRANE Library for titles and abstracts containing terms related to the subject. The search delimiters were analytical and descriptive studies with abstracts in Spanish, German, English or French, with no time limit. The search was updated in January 2015. Of the 398 articles found, 89 were duplicates and only 28 were of interest. Of these, 23 (82.14%) were case and case series reports, 4 (14.28%) were longitudinal studies and 1 (3.57%) was a cross-sectional study. General anaesthesia and …

Effects of mandibular advancement surgery on the temporomandibular joint and muscular and articular adaptive changes--a systematic review.

The objective of this study was to assess the anatomical changes to the condyle and articular disc following mandibular advancement surgery, the adaptation of the masticatory muscles, and the improvement or worsening of temporomandibular disorders (TMD) in patients with pre-existing disorders and those who developed them following surgery. Four databases were searched systematically: PubMed, Scopus, Embase, and Cochrane Library. Of the 544 articles initially selected, 219 were duplicates and a further 165 were excluded on the basis of their titles and abstracts. On reading the full text, 89 were excluded because they were of no interest and 43 because they did not meet the inclusion criteri…

Corticotomies as a surgical procedure to accelerate tooth movement during orthodontic treatment : a systematic review

Background One of the main aims of orthodontists is to reduce the treatment time as much as possible, particularly in view of the rise in demand for orthodontic treatment among adult patients. The objective of this systematic review was to examine the effectiveness of corticotomy as a surgical procedure that accelerates orthodontic tooth movement, together with its possible adverse effects. Material and Methods A systematic review of articles in 4 databases, Pubmed, Cochrane, Scopus and Embase, complemented by a manual search, identified 772 articles. The duplicates were eliminated and a critical reading of titles and abstracts led to the rejection of articles that did not meet the objectiv…

Hypomineralized Second Primary Molars as Predictor of Molar Incisor Hypomineralization

AbstractMolar incisor hypomineralization (MIH) is a developmental defect of dental enamel that shares features with hypomineralized second primary molars (HSPM). Prior to permanent tooth eruption, second primary molars could have predictive value for permanent molar and incisor hypomineralization. To assess this possible relationship, a cross-sectional study was conducted in a sample of 414 children aged 8 and 9 years from the INMA cohort in Valencia (Spain). A calibrated examiner (linear-weighted Kappa 0.83) performed the intraoral examinations at the University of Valencia between November 2013 and 2014, applying the diagnostic criteria for MIH and HSPM adopted by the European Academy of …

Tibial Nerve Block: Supramalleolar or Retromalleolar Approach? A Randomized Trial in 110 Participants.

Of the five nerves that innervate the foot, the one in which anesthetic blocking presents the greatest difficulty is the tibial nerve. The aim of this clinical trial was to establish a protocol for two tibial nerve block anesthetic techniques to later compare the anesthetic efficiency of retromalleolar blocking and supramalleolar blocking in order to ascertain whether the supramalleolar approach achieved a higher effective blocking rate. A total of 110 tibial nerve blocks were performed. Location of the injection site was based on a prior ultrasound assessment of the tibial nerve. The block administered was 3 mL of 2% mepivacaine. The two anesthetic techniques under study provided very simi…

Effectiveness of mandibular advancement appliances in treating obstructive sleep apnea syndrome: A systematic review

Objectives/Hypothesis Mandibular advancement devices are an alternative to continuous positive airway pressure for patients with mild or moderate obstructive sleep apnea/hypopnea syndrome (OSAHS). The main aim of this review was to assess the effectiveness of different devices in treating OSAHS, based on polysomnographic measurements such as the apnea/hypopnea index (AHI) and oxygen saturation, and on changes in the upper airway and improvements in the most common symptoms: snoring and somnolence. Their adverse effects were also noted. Study Design Systematic review. Methods Following an exhaustive search in the Medline, Scopus, and Cochrane Library databases, 22 articles published in the p…

Titanium plate removal in orthognathic surgery: prevalence, causes and risk factors. A systematic literature review and meta-analysis

The purpose of this review was to analyse the prevalence of titanium plate removal in orthognathic surgery, as well as the causes of plate removal, and to determine the associated risk factors. A thorough search of the PubMed, Scopus, Embase, and Web of Science databases was conducted. The inclusion criteria were studies of adult patients who underwent orthognathic surgery in which monocortical titanium plates and screws were placed. Of the 325 references identified, 19 were included in the qualitative synthesis and meta-analysis. Overall, 13.4% (95% confidence interval (CI) 9.6-18.3%) of the patients required the removal of at least one titanium plate; 9.7% (95% CI 6.3-14.6%) of the plates…

Degree of severity of molar incisor hypomineralization and its relation to dental caries

AbstractMolar incisor hypomineralization is a developmental defect of dental enamel associated with rapid caries progression. In order to discover whether molar incisor hypomineralization predisposes to dental caries, a cross-sectional cohort study was conducted in a sample of 414 children aged between eight and nine years. It was found that 24.2% of the children presented molar incisor hypomineralization. Of these, 72% had a mild form and 28% a severe form. Caries prevalence was greater among the children with severe form (60.7%) than in those with mild form (43.1%) or no molar incisor hypomineralization (45.5%). The caries indices were higher in out molar incisor hypomineralization (1.18)…

Influence of immigration and other factors on caries in 12- and 15-yr-old children.

In recent years the Valencia region has undergone mass immigration, mainly of people from eastern Europe, North Africa, and Latin America. The objective of this study was to assess the effect of immigration on caries prevalence and experience in 12- and 15-yr-old children in the Valencia region, and to relate this to other socio-economic and oral hygiene-related variables. The data were obtained from the epidemiological study of oral health carried out in the Valencia Region in 2004. The study group comprised 478, 12-yr-old children and 401, 15-yr-old children. Immigration status, age, toothbrushing frequency, and intake of cariogenic foods between meals showed significant association in a …
