The needle penetrating the tissue can cause stress, anxiety, and pain. Studies have shown that using touch may alleviate pain and reduce patient anxiety. Yet, this has not been tested in pediatric dental patients. Therefore, this study examined the effect of hand-holding on children undergoing local anesthetic injections. Its effect on children’s pain perception was tested, with the hypothesis that pain perception would be lower for children whose hand was held by an assistant. Additionally, the study examined whether hand-holding would affect children’s anxiety levels and cooperation. Fifty-five children, who underwent dental treatment within the Department of Pediatric Dentistry at Tel Aviv University, were recruited. The patients were randomly divided into two groups. In the study group, the assistant gently placed her hand on the patient’s hand during the anesthetic injection. In...

Lately, dentists have embraced rotary instrumentation as a safe and effective alternative. This study aimed to compare the efficacy of root canal preparation in extracted primary molars between manual and two rotary file systems using micro-CT. Thirty-six extracted human second primary mandibular molars were divided into three groups according to the instrumentation method: (1) Manually instrumented (MI) group (n = 9) in which the teeth were treated using K-files up to size 30; (2) Kedo-Ssystem (KS) group (n = 9); (3) ProTaper Gold system (PTG) group (n = 10) and control group (n-8). Each tooth was scanned before and after the retrograde root canal preparation. Residual dentin volume was calculated using micro-CT scans to evaluate the technique’s efficacy. Additionally, the preparation time and procedural errors were recorded for each tooth prepa...

The etching time changes the physical and mechanical surface properties of the etched tooth tissues; therefore, it impacts both etching depth and the bond strength of sealants to the enamel. We examined if reducing the recommended 15 s etching time of primary teeth enamel affects the micro-shear bond strength (µSBS) of pit-and-fissure sealants. The cusps of forty non-carious, extracted human primary molars were separately etched for 8, 15 or 30 s. Then, a pit-and-fissure sealant was placed and light-cured. The µSBS values were evaluated and compared among the three groups. The mean µSBS values ± standard deviations were 34.68 ± 16.93, 34.19 ± 17.35 and 36.56 ± 16.57 MPa in the cusps etched for 8, 15 and 30 s, respectively. No statistically significant differences in µSBS were observed among the three test groups. In this study, we showed for the ...

Factors affecting chronic teeth lesions include nutrition, parental involvement, and executing proper dental health attitude. Professional dentists are perceived as role models for the oral health and hygiene of their families. The purposes of the research were 1. To compare caries rates in the children of pediatric dentists and children of general dentists. 2. To compare children’s nutrition habits between pediatric dentists and general dentists. 3. To compare children’s oral health and hygiene between pediatric dentists and general dentists. 4. To compare children’s usage of fluoride-containing products between pediatric dentists and general dentists. A cross-sectional study was conducted by distributing self-reporting questionnaires to pediatric dentists and general dentists via the social media “snowball” platform.

The current study aims to examine the knowledge of breastfeeding mothers about their baby’s dental health and prevention of ECC while comparing primiparous mothers to multiparous mothers. A total of 165 mothers aged 20–49 y/o participated in the study by completing questionnaires that assessed the knowledge and attitudes of mothers toward their infants’ oral health. Results showed that (1) mothers were found to be highly knowledgeable regarding the oral hygiene of their infants and the recommended breastfeeding best practices (71%); (2) mothers with lower education showed poor knowledge regarding the recommended practices of infant oral health; (3) a large proportion of the mothers in the sample (62%) reported that they usually tasted the food before giving it to their baby, in a way they could transmit bacteria to infants; (4) most of the mothers (68%) were not aware that their d...

However, previous study showed recurrence of the disease in 80% of cases within 12 months. The aim of the present study was to examine the changes in microbial composition of the dental biofilm of these children following treatment. Dental biofilm samples from five children (mean age 45.4 ± 10.1 months) were taken before and three months after treatment and analyzed for microbial composition using Next Generation Sequencing of the microbial DNA extracted from these samples. Although some reductions in the abundance of caries-pathogenic bacteria (e.g., Streptococcus mutans, Streptococcus sobrinus, Rothia dentocariosa and Scardovia wiggisiae) were seen in the post-treatment follow up samples, these reductions were for the most part not statistically significant, and these bacteria remained well above detection levels. Taken together, the results of th...

We examined the oral and gingival health and caries prevalence of 150 postpartum women shortly after giving birth and assessed their knowledge of oral hygiene using a questionnaire. We also compared the oral health knowledge of nulliparous and multiparous women. Although most participants (98.0%) understood the importance of maintaining oral hygiene in children, their overall knowledge of oral health was medium–low, regardless of the number of previous pregnancies. Only 4.6% of women received oral health advice from their obstetrician during their pregnancy. Most participants had a high gingival index score, which correlated with dental pain during pregnancy. In contrast, the number of decayed, missing and filled teeth was significantly lower in first-time mothers. There was a statistically significant positive correlation between women who regularly visit their dentist and...

Mandibular cortical width (MCW) may be used as a surrogate measure for evaluating BMD. We compared the MCW measured on digital panoramic radiographs (DPR) of 38 children and adolescents with ADHD who were treated with methylphenidate for at least 12 months to the MCW of 58 children and adolescents without ADHD (control). The two groups had a similar mean age (p = 0.3). Mean MCW was significantly lower among children with ADHD compared to those in the control group (2.77 ± 0.33 mm vs. 3.04 ± 0.46 mm, p = 0.004). Additionally, each of the MCW sides were significantly smaller in the group with ADHD compared with the control group. In conclusion, treatment with methylphenidate is associated with low MCW in children and adolescents with ADHD. Analysis of MCW on DPR may help in screening children that are at risk of bone health ...

Study design: Cross-sectional survey among dentistry residents and dental specialists working in clinics that provide dental care to children with type 1 diabetes. Results: A total of 166 respondents were included. 42% of respondents perceived that they have sufficient knowledge to treat children with diabetes, in correlation with an average score of 1.9 out of 4 on knowledge questions. Over 80% of dentists decided to treat patients by consulting with the treating physician or by checking HbA1c and glucose blood levels independently. Greater knowledge was associated with a significantly higher tendency of the dentists to determine if the child’s diabetes is controlled, and to refer less often to the hospital. Furthermore, greater knowledge was also associated with dentists’ greater perception that they have enough knowledge, skills and confidence to treat children wit...

The use of sedation in combination with chronic ADHD medication use is also not well defined. This study surveyed the prevalence of ADHD children, management techniques and knowledge of pharmacologic therapies of these children among Israeli dentists. Study Design: A specially designed questionnaire was distributed to all Israeli dentists attending a national conference in 2016. Results: Of the 160 dentists who attended the conference, 96 completed the survey (60% response rate), and they included 46 (51%) pediatric dental specialists and 50 (49%) general dental practitioners. The medications Ritalin and Concerta were most familiar to the respondents (98.9%). Eighty-seven (91.1%) of the practitioners responded that their ADHD patients take their usual doses of any drug for treating ADHD symptoms, regardless of whether or not the dentists intend...

The aim to assess sedation and cooperation levels following sedation with 60% and 70% N2O concentrations in children whose dental treatment failed using 50% N2O concentration. Study design: Children (n=51) aged 5–10 years were included. Sedation started with N2O concentration of 50%; when appropriate cooperation and sedation were not achieved, N2O concentration was increased to 60%, and subsequently to 70% during the same session. Sedation and cooperation levels were the primary outcomes. Adverse events were defined as secondary outcomes. Results: At 50% N2O concentration, five children reached adequate sedation and cooperation and completed their dental treatment, where 32 children completed the treatment at 60% N2O concentration. Fourteen children required a concentration of 70% to complete treatment. For ten of the latter, treatment was successfully completed, while for four, treatme...

The use of sedation in combination with chronic ADHD medication use is also not well defined. This study surveyed the prevalence of ADHD children, management techniques and knowledge of pharmacologic therapies of these children among Israeli dentists. Study Design: A specially designed questionnaire was distributed to all Israeli dentists attending a national conference in 2016. Results: Of the 160 dentists who attended the conference, 96 completed the survey (60% response rate), and they included 46 (51%) pediatric dental specialists and 50 (49%) general dental practitioners. The medications Ritalin and Concerta were most familiar to the respondents (98.9%). Eighty-seven (91.1%) of the practitioners responded that their ADHD patients take their usual doses of any drug for treating ADHD symptoms, regardless of whether or not the dentists intend...

The aim to assess sedation and cooperation levels following sedation with 60% and 70% N2O concentrations in children whose dental treatment failed using 50% N2O concentration. Study design: Children (n=51) aged 5–10 years were included. Sedation started with N2O concentration of 50%; when appropriate cooperation and sedation were not achieved, N2O concentration was increased to 60%, and subsequently to 70% during the same session. Sedation and cooperation levels were the primary outcomes. Adverse events were defined as secondary outcomes. Results: At 50% N2O concentration, five children reached adequate sedation and cooperation and completed their dental treatment, where 32 children completed the treatment at 60% N2O concentration. Fourteen children required a concentration of 70% to complete treatment. For ten of the latter, treatment was successfully completed, while for four, treatme...
