%X This review evaluates randomized controlled trials (RCTs) intervening on adult state anxiety (fear and emotional distress during dental treatment), chronic dental (trait) anxiety or dental phobia (disproportionately high trait anxiety; meeting diagnostic criteria for specific phobia). Seven online databases were systematically searched. 173 RCTs met inclusion criteria, of which 67 qualified for 14 pooled analyses. To alleviate state anxiety during oral surgery, moderate-certainty evidence supports employing hypnosis (SMD=-0.31, 95 %CI[-0.56,-0.05]), and low-certainty evidence supports prescribing benzodiazepines (SMD=-0.43, [-0.74,-0.12]). Evidence for reducing state anxiety is inconclusive regarding psychotherapy, and does not support virtual reality exposure therapy (VRET), virtual reality distraction, music, aromatherapy, video information and acupuncture. To reduce trait anxiety, moderate-certainty evidence supports using Cognitive Behavioral Therapy (CBT; SMD=-0.65, [-1.06, -0.24]). Regarding dental phobia, evidence with low-to-moderate certainty supports employing psychotherapy (SMD=-0.48, [-0.72,-0.24]), and CBT specifically (SMD=-0.43, [-0.68,-0.17]), but not VRET. These results show that dental anxieties are manageable and treatable. Clinicians should ensure that interventions match their purpose-managing acute emotions during treatment, or alleviating chronic anxiety and avoidance tendencies. Existing research gaps underscore the necessity for future trials to minimize bias and follow CONSORT reporting guidelines.
