This
study compares the fluoride release from microlaminated glass ionomer based on glass hybrid technology coated with two different surface coating agents.
A total of 18 samples were divided into ...three groups of six samples each: (1) glass ionomer Equia Forte Fil coated with Equia Forte Coat (Equia+EC), (2) glass ionomer Equia Forte Fil coated with GC Fuji Varnish (Equia+VC) and (3) uncoated glass ionomer Equia Forte (EQUIA cont). Fluoride release was measured using an ion-selective electrode (ORION EA 940) after 24 hours, 4 days, 30 days and 64 days. Repeated measures ANOVA, multiple comparisons, Tukey's test and paired t-test were used to test the differences between the groups.
The differences between the groups and four time points were statistically significant (ANOVA, p<0.0001). Cumulative fluoride ion release after 64 days was 66.01 mg/l, 123.54mg/l and 203.22 mg/l for EQUIA+EC, EQUIA+VC and EQUIA cont, respectively. All the differences were statistically significant except the difference between EQUIA+VC and EQUIA cont after 24 hours.
The amount of released fluoride was significantly lower in the samples coated with nanofilled surface coating agent compared to the samples coated with varnish and uncoated samples.
to determine the mechanical properties of hybrid and high-viscosity glass ionomer cements. Compressive strength and hardness of three glass ionomer cements (GIC) were measured: Ketac ™ Universal ...Aplicap ™, EQUIA Fil® and EQUIA FORTE Fil®, and the SEM sample analysis were performed.
The samples for measuring the compressive strength were prepared using silicone molds with standard dimensions of 6 mm x 4 mm and stored in deionized water for five days, while the samples for hardness measurement were prepared using Teflon molds with a cylindrical opening in the middle, dimensions 2 mm in height and 5 mm in width. For each material, one sample was made (n = 1) and stored in deionized water at 37ºC for 25 days. A representative sample of each material was analyzed using SEM. For the comparison of obtained values, the ANOVA test was used, while Tukey test was used for the multiple comparison.
There were no significant differences between the compressive strength of the three tested materials (p <0.05). The hardness values were: 157 HV0,2 for Ketac ™ Universal Aplicap ™, 47 HV0,2 for EQUIA Fil® and 39 HV0,2 for EQUIA FORTE Fil®, respectively, and were significantly different, implying that Ketac ™ Universal Aplicap ™ has much higher hardness values than the other materials tested. SEM sample analysis revealed similar fracture modes of the tested materials.
It was concluded that there were no statistically significant differences in compressive strength and fracture modes between the tested materials, while Ketac ™ Universal Aplicap ™ hardness results were significantly higher than the ones measured for EQUIA Fil® and EQUIA FORTE Fil®.
The aim of this study was to examine the satisfaction of parents and caregivers of patients who underwent dental treatment in general anesthesia (GA) in a day-care surgery setting.
Anonymous ...questionnaire was sent to parents/caregivers of patients who underwent full mouth restoration in GA. The survey consisted of 4 parts: general data, data about procedure, satisfaction with various aspects of care and the perception of parents/caregivers about the condition of their child in relation to the time before dental treatment in GA.
66 parents/caregivers (30.5%) responded to the questionnaire. Overall satisfaction with the treatment was high (4.69). Respondents expressed the highest degree of satisfaction with communication with nurses (4.92), and the lowest with the waiting time for the procedure (3.89). Parents/caregivers of patients who reported difficulty eating expressed significantly lower overall satisfaction than the subjects whose children did not report difficulty eating. Also, the more treatments the patients underwent, the lower was the overall satisfaction than of those subjects whose children were never treated in such a manner before.
Since patient satisfaction has a beneficial impact on treatment outcome and adherence to preventive recommendations, all health care providers should strive to achieve it.
Posljednjih godina u kliničkoj primjeni dentalnih materijala dogodila se značajna evolucija. Bioaktivni materijali potiču cijeljenje pulpnog i periapikalnog tkiva te ostvaruju interaktivni učinak sa ...stanicama i tkivima. Iz toga proizlazi široko indikacijsko područje i raznolikost primjene kroz restaurativni i regenerativni rezultat terapije u različitim specijalističkim granama dentalne medicine. U ovom prikazu kliničkog slučaja provedena je apikotomija
zuba 21 uz enukleaciju tvorbe, uzimanje uzorka za patohistološku analizu, izradu retrogradnog kaviteta i primjenu bioaktivnog materijala. Retrogradni kavitet je izrađen piezoelektričnim ultrazvučnim nastavkom i zatvoren Biodentinom (Septodont, Saint-Maur-des Fosses, Francuska). Mukoperiostalni režanj je reponiran i zašiven. Radiološki kontrolni pregled proveden je nakon šest mjeseci te nakon godinu dana u svrhu praćenja dinamike cijeljenja koštanog defekta. Cijeljenje lezije uočljivo je već nakon šest mjeseci. Zbog svoje biološke sigurnosti i induktivnoga biološkog učinka te širokoga indikacijskog područja primjene, bioaktivni dentalni materijali fiziološki nadomještaju oštećenu zubnu strukturu, induciraju regeneraciju periapikalnih upalnih lezija te revaskularizaciju i revitalizaciju tkiva.
Burning mouth syndrome is a condition of unknown etiology, characterized by burning symptoms on the otherwise clinically healthy oral mucosa. Central and/or peripheral neuropathy is one of the ...proposed causes for this condition. Psychological component in these patients is also very present, as it is known that BMS patients exhibit high levels of pain, anxiety, and depression. The aim of this study was to evaluate anxiety and depression among patients with burning mouth syndrome and a control group. We also further review and discuss the literature available on this subject.
A total of 93 subjects, divided into two groups, participated in this study. The group of patients with BMS included 43 participants, while the control group consisted of 50 participants. Self-reported STAI (State anxiety and Trait anxiety) and BDI questionnaires were used to evaluate anxiety and depression in subjects in both groups.
BMS group had higher average total scores of state anxiety, trait anxiety and depression. The difference between the BMS group and control group was statistically significant for state anxiety scores and BDI scores.
We might conclude that BMS patients are more anxious (state) and depressed when compared with the control group. However, they do not differ from the control group regarding anxiety as a trait. Thus we might conclude that feeling of anxiety in general starts after the BMS symptoms first occur and last for a longer period of time.
To review the frequency and management of post-discharge complications in patients who underwent dental treatment in general anesthesia (GA) in a day-care surgery setting and identify the factors ...that increase the risk for these complications.
Anonymous questionnaire was sent to parents/caregivers of patients who underwent full mouth restoration in GA at our institution between 1
January 2017 and 31
July 2019. Demographic and clinical data of patients as well as the data about the occurrence and management of complications were collected.
Sixty-six parents/caregivers (30.5%) responded to the questionnaire. Most frequent complications were drowsiness and pain in 40(60.6%) patients. Complications were managed by parents or caregivers with conservative measures at home in 57(91.9%) cases. Phone consultation with dentist was required in 5(8.1%) cases. One patient (1.6%) was readmitted. Younger age and diagnosis were associated with increased risk for drowsiness.
Post discharge complications of dental treatment in GA in a day-care service are common and they can be managed by parent/caregiver with conservative measures at home. The rate of readmission is low. Dental treatment in GA in a day-care service is a safe procedure that can be performed with acceptable risk in carefully selected patients.
Objective: The aim of this study was to evaluate smoking habits, the level of knowledge and attitudes towards smoking, as well as the role of dental professionals in prevention of smoking among ...students of the School of Dental Medicine, University of Zagreb and compare them to attitudes of practicing Croatian dentists. Materials and methods: The study was carried out among 1st and 6th year dental students at the School of Dental Medicine, University of Zagreb and dentists employed in primary practice throughout Croatia. A total of 159 subjects (51 1st and 53 6th year dental students and 55 dentists) participated in the study. Results: The prevalence of smoking was highest among 6th year dental students (39, 6%). It slightly decreased among dentists (34, 5%), while least smokers were found among first year dental students (7, 8%). The majority of dental student smokers expressed a desire to stop smoking (66, 7% of 1st year dental student smokers and 76% of 6th year dental student smokers), while less than half of dentist smokers had the desire to stop - only 45, 8% of them. Dental students of the 1st and 6th year of the study showed a statistically significantly higher level of desire for education about harmful smoking effects and patients counselling to quit smoking compared to dentists. The data gathered in this study indicate that it is necessary to increase awareness among dental professionals about harmful effects of smoking on oral and general health. Also, their awareness about the central role of healthcare workers as promoters of a healthy lifestyle among patients should be raised.
To analyze data on full-mouth rehabilitation under general anesthesia (GA) performed at the University Clinical Hospital Zagreb with emphasis on patient characteristics, type of procedure and ...postoperative complications.
Retrospective chart review of 100 patients treated under GA at the Dental clinic's day care surgery. Patient's demographic (sex, age) and clinical data (diagnosis, GA technique, intubation type, procedure duration, number of carious teeth, presence of visible calculus, number of sealed teeth, fillings, extractions and endodontic treatments, discharge time, postoperative complications) were registered.
Eighty patients were treated under GA because of noncompliance due to different reasons and twenty patients because of either their poor physical condition or extensive dental procedure. Median DMFT per patient was 9(0-21). Eighty nine patients underwent full-mouth dental restoration and 11 patients underwent other types of procedures. Ninety-six patients were safely discharged the same day. Four patients experienced postoperative complications and three of them were hospitalized for another 24-48 hours for postoperative follow-up.
Patients with physical and/or intellectual disabilities have higher caries activity and increased dental treatment needs compared to the general population. Dental treatment under GA in day care service is a safe and effective way of providing dental care for noncompliant patients.
Although it was previously shown that prolonged prophylactic antibiotic exposure and multiple inadequate antibiotic therapies are independent risk factors for multidrug-resistant ventilator ...associated pneumonia there were no studies investigating whether pre-operative prophylactic dose of antibiotics changes oral microbiome and increases the risk of ventilator associated pneumonia. The aim of the study was to determine if pre-operative prophylactic dose of antibiotics affects the oral microbiome, increases the colonization with Gram-negative bacteria and subsequent risk of ventilator associated pneumonia.
Mechanically ventilated adult patients receiving surgical antibiotic prophylaxis were included in the study. The presence of Gram negative microorganisms in the pre-prophylactic and post-prophylactic oral swabs and tracheal aspirates, as well as the occurrence of ventilator associated pneumonia, were analyzed.
Number of patients colonized with Gram negative bacteria in post- prophylactic oral swab was significantly higher compared to oral swab taken before prophylactic antibiotic. On the other hand, the number of patients with Gram- negative bacteria in tracheal aspirates remained similar as in post- prophylactic oral swabs. Moreover, we found that presence of Gram- negative bacteria in both pre- and post- prophylactic oral swabs was in the positive correlation with the presence of Gram- negative bacteria in tracheal aspirates.
This study showed increased colonization of oral cavity with Gram- negative bacteria after preoperative prophylactic antibiotics. Furthermore, receiving two prophylactic antibiotics from WHO Watch list increased the incidence of Gram- negative bacteria in oral swabs and tracheal aspirates, and the risk of ventilator associated pneumonia development.
It is known from the existing literature that metal ions within orthodontic appliances are prone to corrosion due to the salivary and bacterial interplay in the oral cavity. The results from the most ...studies show that levels of salivary nickel and chromium do not increase after the installment of orthodontic appliances.
However, there are no studies on salivary levels of titanium, cobalt, copper and zinc in these patients. Salivary levels of nickel (Ni), titanium (Ti), chromium (Cr), cobalt (Co), copper (Cu) and zinc (Zn) were measured in 42 patients with ceramic brackets and in 42 patients with metal conventional brackets prior to insertion of orthodontic appliances and six months after insertion of orthodontic appliances by means of inductive coupled plasma/mass spectrometry. Statistical analysis was performed by use of Wilcoxon signed rank test and Mann Whitney test with level of significance set at 0.05.
The results showed that salivary level of titanium increased significantly six months after installment of orthodontic appliances. Salivary level of chromium and zinc significantly decreased after installment of orthodontic appliances. There were no significant differences in salivary levels of nickel, titanium, chromium, copper, cobalt and zinc between the patients with metallic and those with ceramic brackets.
We might conclude that the salivary level of titanium increased significantly six months after installment of orthodontic appliances unlike salivary levels of chromium and zinc which significantly decreased after installment of orthodontic appliances, regardless of bracket type which was used.
