“…Using a pulsed-beam system and fiber delivery, it has proved to be a valuable tool for ablating enamel and dentin. It has been studied for Class V cavity preparations and caries removal, and was shown to produce irregular, rugged, and stripped surfaces on dentin, similar to the morphological changes observed in Er: YAG laserirradiated dentin 3,4) . Compared with conventional mechanical drilling systems, laser preparation produced a cavity floor with Ca/P ratio and Knoop hardness number similar to that produced by bur cutting method 5) .…”

The purpose of this study was to investigate the tensile bond strength of composite inlays to human dentin with two different cavity preparation tools (bur versus Er, Cr: YSGG laser) and with two different bonding procedures (total-etch: Variolink II versus self-etch: Maxcem). The specimens were divided into four groups: bur-cut/Variolink II, bur-cut/Maxcem, laser-ablated/Variolink II, and laser-ablated/Maxcem. The following characteristics were then investigated: morphological change, dentin-resin cement interface, surface roughness, and tensile bond strength. Results demonstrated that the tensile bond strengths of the four groups were 19.11±5.88 MPa, 8.54±2.38 MPa, 13.72±3.43 MPa, and 12.11±3.71 MPa, respectively. We concluded that Variolink II provided higher tensile bond strength to composite inlays than Maxcem. On the other hand, the bond strength of Variolink II with dentin cavity prepared by Er, Cr: YSGG laser was statistically lower than that prepared by bur.

In this study we compared the microleakage of conventional glass ionomer cement (GIC) restorations following the use of different methods of root caries removal. In vitro root caries were induced in 75 human root dentin samples that were divided in five groups of 15 each according to the method used for caries removal: in group 1 spherical carbide burs at low speed were used, in group 2 a hand-held excavator was used, and in groups 3 to 5 an Er,Cr:YSGG laser was used at 2.25 W, 40.18 J/cm 2 (group 3), 2.50 W, 44.64 J/cm 2 (group 4) and 2.75 W, 49.11 J/cm 2 (group 5). The air/water cooling during irradiation was set to 55%/65% respectively. All cavities were filled with GIC. Five samples from each group were evaluated by scanning electron microscopy (SEM) and the other ten samples were thermocycled and submitted to a microleakage test. The data obtained were compared by ANOVA followed by Fisher's test (p≤0.05). Group 4 showed the lowest microleakage index (56.65 6.30; p<0.05). There were no significant differences among the other groups. On SEM images samples of groups 1 and 2 showed a more regular interface than the irradiated samples. Demineralized dentin below the restoration was observed, that was probably affected dentin. Group 4 showed the lowest microleakage values compared to the other experimental groups, so under the conditions of the present study the method that provided the lowest microleakage was the Er,Cr:YSGG laser with a power output of 2.5 W yielding an energy density of 44.64 J/cm 2 .

“…58 Bazı literatürlerde lazer ile yapılan çürük temizleme işlemleri sonucunda smear tabakasız bir yüzey oluştuğu belirtilmekte ve bu durumun kavitenin steril ve mikrosızıntının az olmasından dolayı adezyona katkısının olumlu olduğu bildirilmektedir. 51,59,60 Ancak bazı çalışma-larda ise lazer ile açılan kavitelerde duvar marjinlerinin düzensiz oluşundan dolayı mikrosı-zıntı ve adezyona negatif etkisi olduğu savunulmaktadır. 22,61 Sonuç olarak; bu yazı ile alternatif çürük uzaklaştırma yöntemleri ve kavite preparasyonları ile ilgili olarak kapsamlı bir literatür tartışması ve derlemesidir.…”
