Objectives: This study was aimed at assessing the effects of restraint stress and sandblasting; sandblasting with acid etching; Er-Cr: YSGG laser treatment; and propolis coating of implant surfaces on the implant stability quotient (ISQ) of grade 4 titanium dental implant osseointegration in model dogs.
Methods: A total of forty-eight CPTi dental implants were divided into four groups according to surface treatment: group A: sandblasting with acid etching; group B: sandblasting with AlO; group C: Er-Cr: YSGG laser; and group D: propolis coating. Sixteen male dogs of local breed,1-1.5 years of age, weighing 22 ± 3 kg, were divided into two main groups (n-8 dogs each): a non-stressed group (group I) and stressed group (group II). Each of these groups is further divided into four implant groups per surface treatment, A, B, C, and D (two dogs per implant group), each dog has three implants. The ISQ was tested at 0 (baseline), 14, and 90 days with a noninvasive EasyCheck® device. Serum cortisol in the stressed and non-stressed groups was analyzed at 0, 15, 30, 45, 60, 75, and 90 days with a canine cortisol ELISA kit. The data were statistically analyzed with one-way analysis of variance and Tukey's test at a 0.05 level of significance.
Results: For implant stability quotient (ISQ), sandblasting in the non-stressed (group I) had the highest mean value (88.0) at 90-days, whereas sandblasting with acid etching at 14-days had the lowest mean value (82.6). Sandblasting in the stressed (group II) had the highest mean value (88.3) at 90-days, whereas the laser surface treatment had the lowest mean value (72.00) at 14-days. Serum cortisol (ng/μl) at 90 days (143.10 and 195.33 for non-stressed and stressed groups respectively), was significantly higher than other time intervals ( < 0.05).
Conclusions: The ISQ was dependent on surface treatment, and was higher with sandblasting than the other treatments in the stressed and non-stressed groups at 90 days. For all surface-treated implants, the stressed group had significantly higher serum cortisol levels than the non-stressed group.

Objective: To evaluate the shear bond strength (SBS) and adhesive remnant index (ARI) scores of metal brackets to glazed lithium disilicate reinforced glass-ceramics and zirconia according to various surface treatment protocols.
Methods: A total of 240 lithium disilicate ceramic (LD) and 240 zirconia (Zr) blocks were randomly divided according to sandblasting, hydrofluoric acid (HF) etching, universal primer use, and the adhesive system applied. A maxillary canine metal bracket was bonded to each sample with resin cement (Transbond XT, TXT).

Although the surface modifications of the implant have been widely proposed to enhance the osseointegration, their impact on microbial adhesion is still not explored. The present in vitro study was done to compare the bacterial adhesion of S. mutans and Enterococcus faecalis on sand-blasted acid-etched and anodized titanium dental implants.

Aim: This study aims to assess the effects of surface conditioning and different composite types on the surface roughness (SR) and shear bond strength (SBS) between lithium disilicate and clear aligner composite attachments.
Materials And Methods: Eighty ivoclar vivadent pressable (IPS) e.max press specimens were randomly allocated into four groups ( = 20) based on the surface treatment method employed.

Objectives: To in vitro investigate the effect of different implant surface decontamination methods and treatment storing conditions on implant surface morphology and cell viability.
Materials And Methods: Titanium disks with a sand-blasted and acid-etched surface (Promote, PRO) were treated with diamond polishing brushes (BRUSH), nickel-titanium brushes (NITI), or phenol and sulfuric acid-gel (GEL). The disks were stored in saline (-S) or left exposed to air overnight (-A).
