With an increased number of questionnaire-based knowledge, attitude, practice and other types of studies, there is a need to perform evidence-based research in such designs as well. The systematic reviews (SR) and meta-analyses (MA) of the questionnaire-based studies are difficult to conduct and summarise due to the wide variations in the questions included in each of them. The presentation of these reviews often leads to ambiguous conclusions, and meta-analysis is not possible due to wide heterogeneity. This paper aims to highlight a method known as the 'Knowledge-Attitude-Practice' or 'KAP' Heat Map, which was developed and validated for the effective presentation of the outcomes of varied questionnaires in systematic reviews.

This systematic review (SR) aims to evaluate the efficacy of modified coronally advanced flap (mCAF) on clinical and patient-reported outcomes in the treatment of multiple adjacent gingival recessions (MAGRs). Randomized controlled trials (RCTs), case-series and prospective clinical studies on treatment of Miller class I/II or RT1 MAGRs with ≥ 6 months follow-up were identified from the electronic databases and hand-searched journals. Complete root coverage (CRC) was the primary outcome variable. To evaluate treatment effects, meta-analysis was conducted, wherever appropriate. A total of 1395 recessions in 408 patients were evaluated in SR and meta-analysis was performed for four RCTs. Overall CRC achieved with mCAF was 70% and mean root coverage (MRC) ranged from 51.58 to 97.27%. Meta-analysis showed that combination of mCAF with connective tissue graft (CTG) or collagen matrix (CM) demonstrated significantly higher CRC% and recession reduction than mCAF alone. Limited evidence is available to support the use of platelet rich fibrin or enamel matrix derivative or acellular dermal matrix graft along with mCAF to further enhance its efficacy. mCAF is an effective procedure for treating MAGRs and in terms of achieving CRC and MRC. Additional use of CTG or CM further enhances treatment outcomes. [ABSTRACT FROM AUTHOR]
