Antibiotic prophylaxis in surgery – SIGN Guideline 104


The Scottish Intercollegiate Guidelines Network  (SIGN) has just launched their updated guideline on antibiotic prophylaxis in surgery.  SIGN’s first guideline of this topic (SIGN 45)  was published in 2000 and updated in 2008.  The guideline does not aim to provide every surgical speciality with a comprehensive text on preventing  surgical site infection (SSI), but rather [read the full story...]

Little evidence available on treatments for iatrogenic injury to inferior alveolar or lingual nerves

The lingual and inferior alveolar nerves are potential at risk of damage during some oral and maxillofacial surgery procedures. Fortunately the majority are temporary, with resolution taking place within 8 weeks.  Injuries of 6 moths or greater are considered permanent and a range of techniques have used.   The aim of this review was to evaluate [read the full story...]

Study suggests that a risk based non-operative caries treatment and prevention approach may be more cost effective than traditional approaches


Sadly caries remains a significant public health problem across the world, particularly in children. The aim of this study was to assess the cost-effectiveness of caries treatment and prevention strategies in the Netherlands. The study was conducted alongside a randomised controlled trial (RCT) evaluating the effects of two caries prevention strategies compared with regular dental [read the full story...]

Study suggests increased failure risk in root treated teeth with less coronal structure restored with fibre post


The aim of this study was to assess whether the amount of residual coronal structure and the type of cement used for fibre post luting (self-adhesive cement vs. composite core material) affected the four-year survival of root-filled premolars. Patients requiring endodontic treatment and single-unit crown restoration of premolars were eligible.  Patients were divided into two [read the full story...]

Review suggests that glass ionomers had best retention rates in non-carious cervical lesions


The aetiology of non-carious cervical lesions  (NCCLs) has not been fully clarified but they are characterised by a slow and gradual loss of mineralized dental tissue in the absence of dental caries. This results in a saucer or wedge-shaped defect that appears along the cementum–enamel Junction.   The aim of this review was to assess the [read the full story...]

Evidence on whether treatment delay has adverse effect on outcomes following facial fractures is limited


Since the introduction of open reduction and internal fixation the management of facial fractures has changed dramatically. However many uncertainties remain and the importance of the time from injury treatment is one area of dispute.  The aim of this review was to examine the effects of treatment delay on outcomes in the management of facial [read the full story...]

Scant evidence to assess whether root-filled teeth are more at risk of external root resorption during orthodontic treatment

Orthodontically induced external apical root resorption (OIEARR) has been classified as surface resorption caused by loss of cementum.  Usually this is superficial and unidentifiable radiographically but if this occurs apically it can be seen as shortening of the tooth.  Typically OIEARR is less than 2mm and clinically insignificant. OIEARR greater than 4mm is severe and [read the full story...]

Limited evidence for interventions for the management of temporomandibular joint disc displacement without reduction


Temporomandibular joint (TMJ) disc displacement without reduction (DDwoR)  is thought to occur in 2-8% of patients with temporomandibular disorders.  It can cause TMJ pain and restricted opening and is sometimes referred to as ‘closed lock’.  A range of treatment have been tried and the aim of this review, was to investigate the effects of different [read the full story...]

The latest critical summary from the ADA-EBD Center considers a 2012 systematic review from Graziani et al.  The aim of the review was to assess the effectiveness of conservative periodontal surgery (CS) for the treatment of periodontitis-related intrabony defects.   Conservative periodontal surgery was defined as procedures that involved debridement of intrabony defects and root surfaces [read the full story...]
