Review update:
Interventions for replacing missing teeth: different times for loading dental implants
Marco Esposito,  Maria Gabriella Grusovin, Hassan Maghaireh, Helen V Worthington

When people have dental implants in their jaws, they usually wait several months for the bone around the implants to heal before artificial teeth are attached to the implant. During this period they use removable dentures. This review looked at the effects of attaching artificial teeth either the same day that the implant was placed, or early (after only 6 weeks) compared to the usual delay of at least 3 months. 26 clinical trials were included, featuring a total of 1217 participants.

Review update:
Operative caries management in adults and children
David Ricketts, Thomas Lamont, Nicola PT Innes, Edwina Kidd, Jan E Clarkson

Tooth decay (dental caries) is a common problem around the world. It can cost a lot of money to treat and causes infection, pain and the loss of teeth. Tooth decay can be controlled by what are known as ‘non-operative’ methods which include cleaning plaque from teeth thoroughly, advising a healthy diet and using fluoride to prevent the decay getting worse. If the decay progresses these ‘non-operative’ techniques may need to be combined with ‘operative’ management which involves filling and restoring teeth where the holes caused by decay prevent cleaning. The fillings will improve the appearance of the teeth and allow the patient to clean them.  Traditionally dentists have removed all of the decay with a dental drill or instruments before a filling is placed. However, removal of all the decay has some disadvantages, including damage to the nerve of the tooth, toothache and possibly weakening of the tooth structure. This method is known as one step complete caries removal. Despite the large number of fillings and restorations placed worldwide on a daily basis, dentists remain uncertain as to which is the best ‘operative management’ strategy for tooth decay. This review included 8 clinical trials with 934 participants.

Review update:
Sealants for preventing dental decay in the permanent teeth
Anneli Ahovuo-Saloranta, Helena Forss, Tanya Walsh, Anne Hiiri, Anne Nordblad, Marjukka Mäkelä, Helen V Worthington

This review update  considers whether dental sealants are an effective preventative treatment for tooth decay. Dental sealants are intended to prevent the growth of bacteria that promote tooth decay in grooves of back teeth. Sealants are applied onto these grooves by a dentist or by another member of the dental care team. There are several sealant materials available, the main types in use are resin-based sealants and glass ionomer cements. This review summarised information from 34 separate studies involving 6529 young people to whom a variety of dental sealants were used for preventing caries and found evidence that applying sealants to the biting surfaces of the back teeth reduces caries when compared to not using sealants.

New protocol:
Enamel matrix derivative for periodontal regeneration in teeth with furcation involvement
Brian Stevenson, David Ricketts, Joseph LY Liu

This review aims to examine the effects of enamel matrix derivative in the treatment of teeth with furcation involvement and to compare it’s effectiveness with the various guided tissue regeneration procedures used in the treatment of these teeth.

New protocol:
Proximal sealing for managing dental decay in primary and permanent teeth
Mojtaba Dorri, Stephen M Dunne, Wael Sabbah, Bahar Kiani

The primary objective of this review is to evaluate the effects of proximal sealing in managing dental decay in primary and permanent dentition in children and adults.
