“…A total of seven included studies were randomised controlled trials (RCTs) [39, 42, 44–47, 53], of which six were cluster randomised [39, 42, 44, 46, 47, 53] and one was individually randomised [45]. The remaining eight studies followed quasi-experimental designs, with seven being pretest-posttest quasi-experimental studies [40, 41, 43, 48, 49, 51, 52] and one being a non-equivalent groups design [50]. Out of all 15 studies, six involved implementation of interdisciplinary guidelines related to tobacco cessation into the dental setting [43, 44, 46, 47, 49, 51], and the rest explored the implementation of general dental guidelines [39–42, 45, 48, 50, 52, 53].…”
