Fourty-eight human molars assessed clinically and having scores of 0, 3, 4 and 5 based on Interna�onal Caries Detec�on and Assessment System (ICDAS) criteria were inspected. Group ICDAS 0 taken as control for microtensile test. Each group was divided into 4 groups as 1 complete caries removal (CCR) and 3 selec�ve caries removal (SCR) methods: these are stainlesssteel round bur (SSRB), ceramic round bur (CRB), tungsten carbide round bur (TCRB) & bioac�ve glass powder (BAG), TCRB & 29 µm Al2O3, respec�vely (n=3). Following the restora�on, five 1 mm2 s�ckshaped specimens were prepared from each tooth with a slow-speed diamond trim blade (Isomet, Buehler, Lake Bluff, Illinois, USA) (n = 15). Specimens were subjected to µTBS stress at a crosshead speed of 0.5 mm/min (Bisco, Schaumburg, IL, USA). Generalized linear model and Tukey's test were used for sta�s�cal analysis (p ≤ 0.05). Caries removal technique was considered significant between all groups (p≤0.001). The mean of µTBS ranged from 14.2 megapascal (MPa) (%95CI: [12.1-20.5]) to 26.4 (%95 CI:[11.7- 28.4]). The mean±standard devia�on of µTBS were obtained as 19.5±3.9 MPa for SSRB, 16.4±3.3 MPa for CRB, 15.0±3.0 MPa for the TCRB&BAG group and 25.1±2.1 MPa for the TCRB&Al2O3 groups, respec�vely. ICDAS scores showed sta�s�cally significant effect for µTBS values (p≤0.001). Similar µTBS values were obtained for ICDAS 0 (20.1±4.9) and ICDAS 3 (19.9±4.6) scores, which are higher than ICDAS 4 (17.9±4.4) and ICDAS 5 (18.2±5.6) scores. In conclusion, the µTBS for sound den�ne were less affected by the caries removal technique. Within the limita�ons of this study, it can be concluded that the air-abrasion with 29 µm Al2O3 may be preferred to increase µTBS for deep carious lesions.Publication Open Access The effects of caries removal techniques on volume-loss percentage and microtensile bond strength(2024-01-01) KANAR, ÖZLEM; TAĞTEKİN, DİLEK; KORKUT, BORA; KANAR Ö., TAĞTEKİN D., KORKUT B., YANIKOĞLU F.Purpose: This study aimed to calculate the volume loss percentages (VLP) regarding the ICDAS II system and various caries removal techniques (CRT) and to assess the microtensile bond strength (μTBS) in terms of VLP following CRT. Materials and methods: Three-dimensional data of human extracted molars were acquired with an extraoral dental scanner (Ineos x5, Dentsply Sirona) before and after the caries removal. Each ICDAS score group (0,3,4 and 5) was divided into four subgroups according to the CRT: stainless steel bur (Group S), ceramic bur (Group C), tungsten carbide bur (TCB) and air abrasion (AA) with bioactive-glass (Group TB), and TCB and AA with Al2O3 (Group TA). Pre and post-caries removal data were overlaid in a 3D modeling software and were volumetrically measured (n=10). Following the restoration, samples were prepared with non-trimming technique and subjected to microtensile testing. Results: ICDAS II scores were found related the VLP (p< 0.001) and the μTBS (p<0.001). CRT was not effective on VLP (p=0.110), whereas CRT type was significant on μTBS (p<0.001). In Group TA, a strong negative correlation was observed between the μTBS and the VLP for ICDAS 5 score (r=-0.919; p=0.027). Conclusions: ICDAS II can provide a preliminary indication for the amount of VLP and reduction in μTBS following caries removal. The use of 29 μm Al2O3 with air abrasion in deep caries removal may improve μTBS while potentially reducing the VLP.
