ADA-EBD critical summary – survival of various tooth- or implant-supported restorations
6 Responses »
This new critical summary from the ADA-EBD Center for evidence-based dentistry looks at a 2012 review from Pjetursson et al which set out to assess and compare the 5- and 10-year survival of different types of tooth-supported and implant-supported fixed dental prostheses (FDPs) and single crowns (SCs), and to describe the incidence of biological and [read the full story…]
Trial suggests that two types of mineral trioxide aggregate both out perform calcium hydroxide for primary molar pulpotomy
The aim of this study was to evaluate and compare two different white MTA cements as pulpotomy medicaments in human primary teeth, Pro-Root MTA and MTA Angelus. Child patients with deep occlusal carious lesion, which presented potential risk of pulp exposure during complete removal of carious dentin, as determined by clinical and radiographic assessment were [read the full story…]
Trial suggests greater patient satisfaction with microabrasion and at-home bleaching protocol for fluorosis
Dental fluorosis is characterised by bilateral, diffuse, thin and horizontal white striations and stained plaque areas, with pitting and discolouration of the enamel in more severe case. It is caused by excess fluoride ingestion during tooth development and can have an impact on quality of life. The aim of this study was to evaluate the [read the full story…]
Trail suggests similar outcomes with cast and glass fibre posts
The restoration of teeth following root canal treatment (RoCT) can present challenges and posts inserted into the root canal can provide support to enable restoration. The aim of this study was to evaluate the survival of glass fibre and cast metal posts used to restore endodontically treated teeth with no remaining coronal wall. Patients with [read the full story…]
Review suggests that mineral trioxide aggregate had best clinical and radiographic outcomes at 9-12 months for primary molar pulpotomy
When I was training formocresol was the standard dressing for primary teeth following pulpotomy . However, it use is now questionable because of potential adverse effects such as potential carcinogenicity, mutagenicity, and cytotoxicity. Consequently a range of other materials have been investigated, ferric sulphate, gluatraldehyde preparations , mineral trioxide aggregate (MTA), electrosurgery, calcium hydroxide, and laser [read the full story…]
Trial showed similar oral health improvements in nursing-home residents with manual and powered toothbrushes
The 2010 Cochrane review of powered toothbrushes (Deacon et al) provided some evidence that rotational oscillation powered toothbrushes are more effective than other designs. However, the available evidence was based on short-term studies and the differences were small, so the clinical importance was unclear. The aim of this study was to investigate the effect of [read the full story…]
Review finds only a small benefit from antibiotic use in patients with acute sinusitis
Sinusitis is one of the commonest reasons for visiting the doctor accounting for 15% to 21% of all adult outpatient antibiotic prescriptions. Patients may also present at dental practices, as pain from upper posterior teeth can be indistinguishable from sinusitis. Typical signs and symptoms are purulent nasal discharge, postnasal drip, sinus pain at palpation, nasal [read the full story…]
Latest Cochrane Protocol
A new Cochrane protocol has just been published by the Cochrane Effective Practice and Organisation of Care group. With increasing emphasis on the links between general an oral health the adoption of a common risk factor approach is being encouraged. The underlying principle being that general health promotion in dental health-care favours the control of [read the full story…]
Review suggests increased risk of enamel defects in children born pre-term
Enamel defects and other oral abnormalities have been reported in premature children. The aim of this review was to assess whether there is any association between premature birth and enamel opacities or hypoplasia. A search was conducted in PubMed and Embase for follow-up, case control or cross sectional studies published in English German, Danish, Swedish [read the full story…]
Review suggests that both slow and rapid maxillary expansion are effective
Posterior cross-bite is a common malocclusion and a number of approaches to address this with maxillary expansion have been developed. These can be broadly divided into rapid maxillary expansion (RME) and slow maxillary expansion (SME). The aim of this review was to compare the effectiveness of RME and SME for transverse maxillary discrepancy. Searches were [read the full story…]
