[Clinical evaluation of tunnel-restoration]
1Affiliated Stomatology Hospital, Shandong University, Shandong 250012, China.
Objective:
To evaluate the clinical effect of tunnel-restoration.
Methods:
35 teeth with pulpitis or periapical periodontitis caused by interproximal caries were selected. Tunnel-restoration was used after endodontic treatment. Clinical examinations were taken to follow up all the teeth at one year and two years respectively after treatment.
Results:
At one year after treatment, 35 cases were followed up, the rate of success was 100%. At two years after treatment, 33 cases were followed up and 2 cases were lost, the rate of success was also 100%.
Conclusions:
Proximal contact point and marginal ridge of the teeth were preserved by using tunnel-restoration, which is very important to restore proximal contact, enhance the ability of resistance to fracture, and has good clinical effect.
