200Issue 2 of the Cochrane Library for 2013 was released today, and features one new review and three new protocols from the Oral Health Group.

We now have a total of 200 published systematic reviews and protocols on the Library, congratulations to all of our authors, editors and referees on this fantastic achievement!

New review:
Dental extractions prior to radiotherapy to the jaws for reducing post-radiotherapy dental complications
by Shiyana Eliyas, Ahmed Al-Khayatt, Richard WJ Porter, Peter Briggs

This new review aimed to assess the effects of maintaining the patient’s natural dentition during radiotherapy in comparison to extracting teeth before radiotherapy in areas that are difficult to access by the patient and the dentist, should reduction in mouth opening occur after radiotherapy to the jaws. No clinical trials were identified, and there is no high quality evidence on this clinically important topic.

New protocol:
Interventions for the treatment of oral and oropharyngeal cancers: targeted therapy and immunotherapy
by Kelvin KW Chan, Anne-Marie Glenny, Susan Furness, Helen V Worthington

This review is the fourth in a series of Cochrane reviews looking at different treatment modalities for oral cavity and oropharyngeal cancers: surgical treatment, chemotherapy and radiotherapy. There is a great deal of current research into new therapies for cancer and many of these make the headlines in the news. However, there is a significant time lag between laboratory discoveries and the introduction of new treatments into clinical care. This review will evaluate the randomised controlled trials of targeted and immunological therapies for patients with oral cavity or oropharyngeal cancer.

New protocol:
Maxillary distraction osteogenesis versus orthognathic surgery for cleft lip and palate patients
by Dimitrios Kloukos, Piotr Fudalej, Patrick Sequeira-Byron, Christos Katsaros

The conventional orthognathic surgery for correction of maxillary retrusion/hypoplasia is a Le Fort I osteotomy. Distraction osteogenesis is the surgical process of correction of skeletal deformity utilizing bone lengthening by gradual mechanical distraction. This review will compare the effectiveness of the two methods in patients with orofacial clefts.

New protocol:
Professionally-applied chemically-induced whitening of teeth in adults
by Alonso Carrasco-Labra, Romina Brignardello-Petersen, Nicolás Yanine, Ignacio Araya, Gabriel Rada, R Graham Chadwick

Professionally-applied bleaching treatments have been used for a long time. Despite all of the information available, it is difficult for clinicians to determine which is the most effective treatment for tooth discolouration and the level of potential harms of these treatments. This review aims to assess the evidence about the beneficial and adverse effects of in-office, professionally-applied chemically-induced whitening of teeth in adult patients. It will complement another Cochrane systematic review of the evidence for the use of home-based treatment methods.
