Impact of asepsis technique on implant success. A review.

Asepsis is described as a state free from microorganisms. In medicine, an aseptic environment is necessary and expected to avoid the spread of infection through contact between persons, sprays and splashes, inhalation, and sharps. Most dental procedures are performed in a "clean "environment with the common use of personal protective equipment (PPE) such as disposable gloves, masks and protective eyewear with disinfection of surfaces and sterilization of instruments.

No evidence that bonding is needed for amalgam restorations.

Data sourcesRelevant databases were searched for the review such as the Cochrane Oral Health Group Trials Register, Medline, EMBASE, clinical trials.gov, WHO International Clinical Trials Registry Platform.Study selectionRandomised controlled trials comparing adhesively bonded versus non-bonded class I and II amalgam restorations in permanent molars and premolars.

To cord or not to cord? That is still a question.

Data sourcesA broad computerised search with similar key terms was performed in different databases that included: Ovid Medline, Thomson's ISI Web of Science, PubMed, Science Direct, EMBASE and the Cochrane Library. Grey literature, dissertations, abstracts and theses were searched too. Reference lists of the selected articles were hand-searched.

Implant outcomes poorer in patients with history of periodontal disease.

Data sourcesMedline and Embase databases and bibliographies of all included articles and relevant review articles were screened for possible inclusion.Study selectionLongitudinal studies were included reporting on implant survival, success, incidence of peri-implantitis, bone loss and periodontal status and on partially dentate patients with a history of treatment for periodontitis. There were no language restrictions for the included studies.

Accuracy of dental radiographs for caries detection.

Data sourcesMedline, Embase, Cochrane Central and grey literature, complemented by cross-referencing from bibliographies. Diagnostic reviews were searched using the Medion database.Study selectionStudies reporting on the accuracy (sensitivity/specificity) of radiographic detection of primary carious lesions under clinical (in vivo) or in vitro conditions were included.

The impact of smoking on failure rates, postoperative infection and marginal bone loss of dental implants.

Data Sources: Electronic searches were undertaken in PubMed/Medline, Web of Science, Cochrane Oral Health Group Trials Register as well as hand searching.

Study Selection: Clinical human studies, either randomised or not, providing outcome data for dental implant failure in smokers and non-smokers in any group of patients with no follow-up restrictions. Patients smoking a minimum of one cigarette a day were classified as smokers and implant failure was considered as the complete loss of the implant.

Unclear results for the use of botulinum toxin therapy for TMD pain.

Data Sources: A comprehensive search was carried out on major databases such as PubMed, EMBASE and Cochrane CENTRAL. Reference lists of the included studies were explored along with journals likely to contain studies relevant to the topic. The search was restricted to the English language.

Antibiotic prophylaxis for dental implant placement?

Data Sources: Electronic searches without time or language restrictions were performed in PubMed, Web of Science and the Cochrane Oral Health Group trials Register. A vast manual search was done in many dental implant-related journals. Reference lists were scanned for possible additional studies.

Antibiotic use at dental implant placement.

Data Sources: Cochrane Oral Health Groups Trial Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via OVID and EMBASE via OVID. Databases were searched with no language or date restrictions.

Study Selection: Two authors independently reviewed the titles and the abstracts for inclusion.

Trials needed to identify best management of iatrogenic inferior alveolar and lingual nerve injuries.

Data Sources: The Cochrane Oral Health Group's Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), Medline and Embase databases were searched with no language or date restrictions.

Study Selection: Three reviewers independently selected studies. Randomised controlled trials (RCTs) involving interventions to treat patients with neurosensory defect of the inferior alveolar or lingual nerve or both as a sequela of iatrogenic injury were considered.
