The present study aims to assess oral health behavior and awareness of the young population in Turkey. Methodology: A sample of 2,740 students (1309 male, 1431 female) from 5 different universities studying 10 different degree subjects completed a questionnaire related to their oral health behavior. Age, gender and degree subjects were also recorded. The data were analyzed using SPSS 21.0. Results: 66.6% of the students brushed their teeth twice or more times daily. The brushing frequency of students studying different degree subjects is significantly different(p<0.01). Dental students have the highest brushing frequency whereas sports students have the lowest. 38% of the participants indicated that they use mouthwash; however, only 21.2% used it daily. 21.2% of the participants visit a dentist once or twice per year. 50.9% of the participants experience bleeding while brushing. Only 28.8% had regular scaling and polishing. 22.6% of the participants smoke, while 18.8% stated that they have halitosis. Conclusion: The present study indicated that oral health behavior of young population needs to be further improved. Therefore, oral health education programs should be initiated to emphasize the importance of oral hygiene.

Summary: Dental fluorosis (DF) is a developmental disturbance of enamel caused by excessive ingestion of fluoride on ameloblasts during enamel formation. The clinical manifestations depend on the severity of fluorosis. In mild cases, there are white opaque striations across the enamel surface, whereas in more severe cases, the porous regions increase in size, with enamel pitting, and secondary discoloration of the enamel surface. Patients often suffer from the discoloration and the pitted surface of the teeth which are the major characteristics leading to an unaesthetic appearance. A minimally invasive treatment approach of inoffice bleaching followed by a resin infiltration technique was applied to enhance the porous fluorosed enamel surface. The combination of the two techniques resulted in a perfectly satisfactory aesthetic outcome with a clinical follow-up for 12 months.

Methods: Polished human enamel samples were exposed to fluoride varnishes: Bifluorid10 ® (NaF&CaF 2-45200 ppmF), Duraphat ® (NaF 22600 ppmF), Fluor-Protector ® (difluorsilane 1000 ppmF) and a control coating of copal ether varnish (0 ppmF) group and a deionized water group. For each group of 16 samples, nine cycles of erosion and nine cycles of erosion-abrasion [1 cycle = erosion (0.3% citric acid, pH 3.2, 5 min) + artificial saliva (1 h, pH 7.0) + abrasion (120 linear strokes in artificial saliva from Oral B medium soft brushes 300 g loading]. The change in the enamel surface was evaluated using optical profilometry. Results: Duraphat ® and Bifluorid10 ® applications had a median (IQR) step height of 4.21 um (1.59) and 5.01 um (1.02). This was statistically significantly less than Fluor-Protector ® 6.83 um (1.25), copal ether 7.22 um (1.97) and water 7.39 um (1.96) (p < 0.001). For erosion-abrasion, both Duraphat ® and Bifluorid ® had statistically lower step heights than the other products (p < 0.01). Conclusions: The action of fluoride in a range of single-application topical varnishes was effective in reducing enamel wear from erosion and erosion-abrasion in this laboratory study.

Material and Methods: Seventy-two cavities were prepared on caries-free third molars (n = 8). After sterilization, teeth were inoculated with S. mutans for 48 h. One cavity of each tooth was used to evaluate the infection. Following inoculation, infected cavity surfaces were treated either with (1) Er:YAG Laser (1W; 5x5s, Smart 2940D Plus, Deka Laser), (2) Ozone (80s; HealOzone, Kavo), (3) ErYAG-Ozone combination, (4) Er:YAG-Ozone-CHX combination, (5) Chlorhexidine (CHX), (6) Clearfil Protect Bond (PB), (7) potassium-titanyl-phosphate (KTP) Laser (1W; 60 s, SMARTLITE D, Deka Laser), (8) KTP-Ozone combination, and (9) KTP-Ozone-CHX.

Objective: This research is aimed at determining the changes in individuals' knowledge, attitudes and behaviours regarding oral health in terms of nutritional habits, daily oral care and the provision of dental services during the quarantine process in the Coronavirus disease-19 (COVID-19) pandemic. Materials and Methods: A total of 1010 volunteers (age>18) participated in this online survey which was designed to evaluate the participants' demographic information, oral hygiene habits, experiences about oral health and nutritional trends throughout the lockdown period of the COVID-19 pandemic. Results: According to the dietary habits scores, there was a tendency towards dietary consumption that would positively affect oral health (0.381±1.76) (mean ± standard deviation). During this period, 11.4% of women and 20.2% of men smoked less. The frequency of brushing teeth in 20.6% of the participants, flossing in 9.4% and using mouthwash in 28.7% increased. Moreover, the frequency of brushing teeth, flossing and using mouthwash in 7.8%, 7.1% and 7.5% of the participants, respectively, decreased. 67.8% of the participants believed that oral health and general health were related to each other, and 80.5% thought that there was a risk of transmission of COVID-19 in dental treatment. Oral health problem was experienced in 21.7% of the participants during the COVID-19 pandemic. Finally, according to our survey, 25.6% of these people visited the dentist, while 74.4% did not. Conclusion: During the quarantine period, positive changes were observed in individuals' nutrition and smoking behavior. Due to the pandemic, individuals who had oral health problems had reservations about seeking treatment, and treatment services were disrupted. It would be beneficial to increase the public's awareness about the re-planning of dental treatment services due to the pandemic conditions, and the measures taken for the protection of oral health.

Thirty-four patients aged 14-46 years (mean age, 27.1 years) comprised the study group. Twenty-six patients received two class IV restorations and eight patients received four class IV restorations. For each patient, half the number of restorations were performed using a nanohybrid composite (Ceram X duo) and the remaining half used a nanofilled resin composite (Filtek Supreme XT), with two- (XP Bond) and three-step (Scotchbond Multipurpose) etch-and-rinse adhesives, respectively. Two experienced examiners evaluated the restorations for retention, color match, marginal discoloration, wear/loss of anatomic form, caries formation, marginal adaptation, and surface texture to compare the baseline (after placement) and annual recalls over 5 years.
