High fear of intra ‐oral injections: prevalence and relationship to dental fear and dental avoidance among 10‐ to 16‐yr‐old children
The present study aimed to: (i) estimate the prevalence of self‐reported high fear of intra‐oral injections, high blood‐injury fear, and injection fear; (ii) explore the overlap between high fear of intra‐oral injections and high fear of dental treatment; and (iii) evaluate the possible consequence of high fear of intra‐oral injections in terms of avoidance of dental care. The sample included 1,441 subjects, 10‐ to 16‐yr of age, attending elementary schools in a county of Norway. Data were collected using questionnaires that were completed in classrooms. The survey instruments used were the Intra‐Oral Injec...

Efficacy of interdental calibrated brushes on bleeding reduction in adults: a 3 ‐month randomized controlled clinical trial
This study investigated the effect of interdental brushes on the reduction of interproximal bleeding in adults without periodontal disease. Forty‐six adults were enrolled in a 3‐month, observer‐blinded, parallel‐group randomized control trial. The test group used a standard manual toothbrush twice daily and an interdental brush daily. The control group used a standard manual toothbrush. At each visit, a calibrated colorimetric probe was used in all interdental spaces to determine the appropriate size of the interdental brush required, the brush of the corresponding size was introduced into the interproximal space, ...

Measurement of saliva flow rate in healthy young humans: influence of collection time and mouthrinse water temperature
The aim of the current study was to determine if unstimulated saliva flow (measured in μl min−1) is affected by different durations of sample collection and by temperatures of mouthrinse water used before sample collection. In randomized order, participants provided 10 samples of unstimulated saliva at time points ranging from 1 to 6 min after rinsing with different temperatures of water (10, 20, and 30°C). Data were analysed by one‐way anova with post‐hoc tests. Test–retest reliability was assessed using Bland–Altman plots and correlation coefficients. A larger volume of saliva was obtained over a longer colle...

Genetic variation may explain why females are less susceptible to dental erosion
Not all individuals at risk for dental erosion (DE) display erosive lesions. The prevalence of DE is higher among male subjects. The occurrence of DE may depend on more than just acidic challenge, with genetics possibly playing a role. The aim of this study was to investigate the association of enamel‐formation genes with DE. One premolar and a saliva sample were collected from 90 individuals. Prepared teeth were immersed in 0.01 M HCl (pH 2.2), and enamel loss (μm) was measured using white light interferometry. DNA was extracted from saliva, and 15 single‐nucleotide polymorphisms were analysed. Allele and genotype f...

Advanced dental maturity of Finnish 6 ‐ to 12‐yr‐old children is associated with high energy intake
We studied the association of dental maturity with body mass index (BMI), energy intake, and macronutrient intake. A randomly selected subset (n = 148) of the Special Turku Coronary Risk Factor Intervention Project (STRIP) was invited to an oral follow‐up study, and the 6‐ and 12‐yr‐examination data (n = 111, 60 boys) were used. Food records for four consecutive days and BMI values were extracted from the databank of the main STRIP project. The developmental stage of seven permanent mandibular teeth was assessed using panoramic radiographs. The resulting maturity scores were converted to dental age estimates. Three...

The burden of disease of dental anxiety: generic and disease ‐specific quality of life in patients with and without extreme levels of dental anxiety
The aim of this study was to compare disease‐specific (oral health‐related) quality of life (OHRQoL), assessed using the Oral Health Impact Profile‐14 (OHIP‐14), and generic (health‐related) quality of life (HRQoL), assessed using the EuroQol5D (EQ‐5D‐5L), in patients with severe dental anxiety (who were visiting a centre for special care dentistry) with a control group from the general population. Seventy‐six patients with severe dental anxiety [Dental Anxiety Scale (DAS) score ≥ 13] were matched, according to age, gender, and socio‐economic status, to a control group of 76 participants in a larger epi...

Buffering of protons released by mineral formation during amelogenesis in mice
We examined the effects of reduced bicarbonate secretion and the presence or absence of amelogenins on ameloblast modulation and enamel mineralization. To that end, the composition of fluorotic and non‐fluorotic enamel of several different mouse mutants, including enamel of cystic fibrosis transmembrane conductance regulator‐deficient (Cftr null), anion exchanger‐2‐deficient (Ae2a,b null), and amelogenin‐deficient (Amelx null) mice, was determined by quantitative X‐ray microanalysis. Correlation analysis was carried out to compare the effects of changes in the levels of sulfated‐matrix (S) and chlorine (Cl; f...

Effect of silica coating on the bond strength of milled pure titanium to dental porcelain
The objective of this study was to evaluate the bond strength of machined pure titanium, with an intermediate coating of silica, to dental porcelain. In this work, 24 specimens of milled pure titanium were prepared and randomly divided into test and control groups, in which the test group was coated with silica using the sol‐gel dipping technique. The metal–ceramic bond strength was evaluated, according to ISO 9693 standards, using the three‐point bending test, and scanning electron microscopy and energy‐dispersive spectroscopy were used to study the microstructure and elemental composition of the specimens. The bo...

Influence of duration of phosphoric acid pre ‐etching on bond durability of universal adhesives and surface free‐energy characteristics of enamel
The purpose of this study was to evaluate the influence of duration of phosphoric acid pre‐etching on the bond durability of universal adhesives and the surface free‐energy characteristics of enamel. Three universal adhesives and extracted human molars were used. Two no‐pre‐etching groups were prepared: ground enamel; and enamel after ultrasonic cleaning with distilled water for 30 s to remove the smear layer. Four pre‐etching groups were prepared: enamel pre‐etched with phosphoric acid for 3, 5, 10, and 15 s. Shear bond strength (SBS) values of universal adhesive after no thermal cycling and after 30,000 or 60...

Prevalence and patterns of permanent tooth agenesis in individuals with Down syndrome: a meta ‐analysis
In conclusion, individuals with Down syndrome display high prevalence rates and severity of agenesis of permanent teeth. Proper and timely diagnosis of missing permanent teeth is thus necessary, to allow a more comprehensive long‐term treatment plan and a more favorable prognosis in these individuals.

Interaction between intra ‐oral cinnamaldehyde and nicotine assessed by psychophysical and physiological responses
This study investigated whether cinnamaldehyde modulates nicotine‐induced psychophysical and physiological responses in oral tissues. Healthy non‐smokers (n = 22) received, in a randomized, double‐blind, crossover design, three different gums containing 4 mg of nicotine, 20 mg of cinnamaldehyde, or a combination thereof. Assessments of orofacial temperature and blood flow, blood pressure, heart rate, taste experience, and intra‐oral pain/irritation area and intensity were performed before, during, and after a 10‐min chewing regime. Cinnamaldehyde increased the temperature of the tongue and blood flow of the lip, ...

The antibacterial activity of chlorhexidine digluconate against Streptococcus mutans biofilms follows sigmoidal patterns
The aim of this study was to determine the pattern of the antibacterial activity of chlorhexidine digluconate (CHX) against mature Streptococcus mutans biofilms. Streptococcus mutans biofilms were formed on saliva‐coated hydroxyapatite discs and then treated with 0–20% CHX, once, three times, or five times (1 min per treatment) during the period of mature biofilm formation (beyond 46 h). After the treatments, the colony‐forming unit (CFU) counts of the treated biofilms were determined. The pH values of the spent culture medium were also determined to investigate the change in pH resulting from the antibacterial activ...
