Primary Outcome Measures

Name	Time	Method
- Sensitivity of the operated tooth after 1, 2, 4, 12, 24 weeks and after 1 and 5 years: for this purpose, the test tooth is brought into contact on both sides (buccal and palatal) with the aid of a plastic pellet sprayed with cold spray (Omnident-Dental Handelsgesellschaft mbH, Rodgau Nieder-Roden, Germany) and the patient is asked whether he or she perceives the cold on the tooth. In addition, it is tested by means of a commercial dental electrostimulation tester (Digitest ™ II Pulp Vitality Tester, Parkell Inc., Edgewood, NY, USA). For this purpose, the angled end piece for the posterior area of the tester with its metallic end is brought directly into tooth contact, after on the contralateral side a supplied lip hook was hooked to ensure a flow of current. The tester should be set to medium and should not exceed one cycle of increasing current (14 seconds). If the patient perceives a current flow in this cycle, the test is considered positive, otherwise negative.
