简要总结
Few studies evaluate the outcomes beyond 1 year follow up for gingival recessions treatments using the tunnel technique in combination with connective tissue graft. The aim of this randomized controlled trial (RCT) was to compare the 4-year outcomes of the CAF versus the pouch/tunnel (TUN) technique both associated with CTG.

结局指标
主要结局
Mean Root Coverage change
时间窗: at 6 months and 4 years.
The status of the Mean Root Coverage was recorded at 6 months and 4 years follow-up visits. The scale is in mm. More long it is, best it is Minest long it is, worst it is
Plaque Index Change
时间窗: baseline, 6 months and 4 years
The plaque accumulation is assessed at baseline, 6 months and 4 years follow-up visits using a 0-1 scoring system, 0 being the the highest value, 1 being the lowest result (0 =No detectible plaque ; 1 = Plaque can be seen by the naked eye)
Bleeding on probing score change
时间窗: baseline, 6 months and 4 years
The bleeding tendency is assessed at baseline, 6 months and 4 years follow-up visits as : 0 No bleeding when a periodontal probe is passed along the gingival margin adjacent to the implant; 1 Isolated bleeding spots visible ; 2 Blood forms a confluent red line on the margin; 3 Heavy or profuse bleeding.
Gingival thickness change
时间窗: baseline, 6 months and 4 years
The gingival thickness was recorded at baseline, 6 months and 4 years follow-up visits. The scale is in mm. More thick is it, best it is Minest thick it is, worst it is
Keratinised mucosa height change
时间窗: baseline, 6 months and 4 years
The status of the keratinised mucosa height was recorded at baseline, 6 months and 4 years follow-up visits. The scale is in mm. More large is it, best it is Minest large it is, worst it is
Recession width change
时间窗: baseline, 6 months and 4 years
The status of the recession width was recorded at baseline, 6 months and 4 years follow-up visits. The scale is in mm. More large is it, worst it is Minest large it is, best it is
PES Assessment change
时间窗: Baseline, 6 months and 4 years
The PES was assessed according to the seven parameters described by Fürhauser (Fürhauser et al., 2005).
