Materials for retrograde filling in root canal therapy
Honglin Li, Zhiyong Guo, Chunjie Li, Xiangyu Ma, Yan Wang, Xuedong Zhou, Trevor M. Johnson, Dingming HuangKey messages- Due to a lack of robust evidence, the benefits and risks of different materials used for retrograde filling in root canal therapy are unclear.- The evidence is not robust enough to determine which material is best to use in retrograde filling.- We need future studies to strengthen the evidence.What is retrograde filling in root canal therapy?
Future of Evidence Synthesis in Cochrane
In August 2021, Cochrane Review Groups (CRGs) in the UK received confirmation from the UK National Institute for Health Research (NIHR) informing them about the Department of Health and Social Care (DHSC) decision to cease all funding at the break-point in the current contract at the end of March 2023.

Diagnostic tests for oral cancer and potentially malignant disorders in patients presenting with clinically evident lesions
Tanya Walsh, Richard Macey, Alexander R. Kerr, Mark W. Lingen, Graham R. Ogden, Saman WarnakulasuriyaWhy is it important to improve the detection of oral cancer?Persistent abnormal patches or sores in the mouth may represent mouth cancer or oral potentially malignant disorders (OPMDs). OPMDs can sometimes turn into mouth cancer, but if identified early enough patient outcomes can be improved.What is the aim of this review?
Interventions for treating cavitated or dentine carious lesions
Falk Schwendicke, Tanya Walsh, Thomas Lamont, Waraf Al-yaseen, Lars Bjørndal, Janet E Clarkson, Margherita Fontana, Jesus Gomez Rossi, Gerd Göstemeyer, Colin Levey, Anne Müller, David Ricketts, Mark Robertson, Ruth M Santamaria, Nicola PT InnesKey messagesFor decayed baby (primary) teeth, putting an off‐the‐shelf metal crown over the tooth or only partially removing decay before placing a filling may be better than the conventional treatment of removing all decay before filling.
Laser therapy for dentinal hypersensitivity
Mina Mahdian, Soodabeh Behboodi, Yumi Ogata, Zuhair S NattoKey messages‐ Lasers may slightly reduce pain after 24 hours. They may reduce pain beyond 24 hours but the evidence is very uncertain.‐ Lasers do not appear to cause adverse (unwanted) effects.‐ We need future studies to strengthen the evidence and investigate the impact of laser treatment on quality of life.What causes tooth hypersensitivity?
Visual or visual‐tactile examination for the diagnosis of dental caries

Rubber dam isolation for restorative treatment in dental patients
Cheng Miao, Xiaoyu Yang, May CM Wong, Jing Zou, Xuedong Zhou, Chunjie Li, Yan WangKey messages‐ When a rubber dam is used to isolate teeth instead of cotton rolls, tooth repairs may be more likely to remain in place and be in good condition after six months.‐ We need to conduct more studies in this area, to strengthen the evidence. These studies need to use robust methods, follow people beyond six months, and investigate adverse (unwanted) effects and costs.
What works best to preserve the jaw bone after tooth extraction?
Momen A Atieh, Nabeel HM Alsabeeha, Alan GT Payne, Sara Ali, Clovis M Faggion Jr, Marco EspositoWhy is this question important?Tooth extraction is a common procedure that can be used for example to:- remove damaged or diseased teeth;- remove teeth that are in the wrong place; or- make room for other teeth.After a tooth extraction, the part of the jaw bone that used to hold the tooth shrinks because it is no longer needed to support the tooth. If the bone shrinks too much, this can:
