“…24 Nicotine in tobacco smoke has been reported to reduce the cellular healing response and increase the levels of the oral bacterial count (a potential risk factor that may lead to peri-implantitis) in CS. 25 The findings of the present study corroborates with the study by Barão and colleagues 25 since the number of peri-implant sites with plaque accumulation were statistically significantly higher among individuals in CS and STU compared with NTU. It is also noteworthy that percentage of peri-implant sites with positive BOP were significantly higher in STU and NTU compared with participants in CS.…”

“…Moreover, the results of a recent systematic review and meta-analysis indicated that nicotine from tobacco smoke impairs new bone formation around dental implants and boneto-implant contact (28). Furthermore, nicotine has also been reported to reduce the cellular healing response and increase the accumulation of oral biofilm (a potential risk factor that may led to peri-implantitis) in smokers (29). The present results support the study by Barao et al (29), since the number of peri-implant sites with plaque accumulation was significantly higher among individuals in Groups 1 and 2 than in Group 3.…”

The aim was to compare the peri-implantclinical and radiographic inflammatory parameters and whole salivary cotinine levels among cigarette smokers (CS), waterpipe smokers (WS) and neversmokers (NS). Thirty-four CS (Group 1), 33 WS (Group 2), and 31 NS (Group 3) were included. Peri-implant plaque index (PI), bleeding-on-probing (BOP), and probing depth (PD) were measured, and crestal bone loss (CBL) was assessed on standardized digital radiographs. Unstimulated whole saliva samples were collected and whole salivary cotinine levels were measured. Peri-implant PI and PD were higher in Groups 1 (P < 0.05) and 2 (P < 0.05) than in Group 3. Peri-implant BOP was significantly higher in Group 3 than in Groups 1 (P < 0.01) and 2 (P < 0.01). Peri-implant MBL was significantly higher in Groups 1 (P < 0.05) and 2 (P < 0.05) than in Group 3. There were significant differences in PI, BOP, PD, and CBL between Groups 1 and 2. There was no significant difference in the whole salivary cotinine levels in Groups 1 and 2. Peri-implant sites with plaque accumulation, PD, CBL, and whole salivary cotinine levels were higher in CS and WS than in NS, but did not differ between CS and WS.

“…The saliva covered discs were transferred to wells of another 24-well plate with 100 µL of S. sanguinis cell suspension (10 7 cells/mL) and 900 µL of 1% glucose-supplemented BHI broth. The plates were incubated in 10% CO 2 (v/v) at 37 • C for 1.5 h (adhesion phase) [24]. Subsequently, the discs were washed in 2 mL of 0.9% NaCl solution to remove the non-adhered cells.…”

“…Subsequently, the discs were washed in 2 mL of 0.9% NaCl solution to remove the non-adhered cells. Finally, they were transferred to a 24-well culture plate containing fresh 1% glucose-supplemented BHI broth and incubated in 10% CO 2 at 37 • C for 48 h, with the culture medium renewed every 24 h [24].…”

“…The resulting suspension was used to analyze the biofilm by means of the serial dilution in 0.9% NaCl, with 20 µL of the specimens plated in triplicate in Trypticase Soy Broth (TBS) (Difco Laboratories). The TBS plates were incubated in 10% CO 2 at 37 • C for 48 h, for the subsequent number count of the colony forming units (CFU) per mL [24].…”

Bacterial Adhesion on Lithium Disilicate Ceramic Surface Exposed to Different Hydrofluoric Solutions

et al. 2018

Abstract:The effect of Fluorine solutions on the surface and bacterial adhesion of lithium disilicate is a concern. The aim was to evaluate the surface roughness and the adhesion of Streptococcus sanguinis on lithium disilicate ceramic, under the influence of different solutions containing Fluorine. Forty lithium disilicate (IPS e.max Press Impulse) discs (2.5 × 5 mm) was divided into 4 groups (n = 10): artificial saliva (Group AS), 0.2% sodium fluoride (Group NaF), 1.23% acidulated phosphate fluoride gel (Group APF), and mouthwash (Group MW). Roughness analyses were performed before and after the immersion. The surface aspect was evaluated by scanning electron microscopy (SEM) and the adhesion of Streptococcus sanguinis were evaluated after immersion in the solutions. The data obtained were submitted to the analysis of variance (ANOVA) and the Tukey test (α = 0.05). The Group APF presented a bigger roughness (3.263), statistically different to the other solutions. The bacterial adhesion in the Group APF (5.85) presented statistical difference to the other solutions. The SEM micrographs showed a rougher surface in Group APF. The 1.23% APF gel promoted major surface roughness and bacterial adhesion and could be inadequate for the use of patients with lithium disilicate ceramic restorations. Clinical significance: The Fluorine solution can affect the lithium disilicate ceramics, generating a rough and non-esthetic surface. This altered surface could be susceptible to bacterial adhesion, being directly related with periodontal health, the longevity of the restoration and the success of the rehabilitation.
