Evaluation of the relationship between tooth decay and trabecular bone structure in pediatric patients using fractal analysis: a retrospective study.

Purpose: The movement of chewing affects the growth and development of the stomatognathic system. Tooth decay, which is known to have effects on chewing, can affect the jaw bone due to its indirect effect on the mechanical forces transmitted to the jaw bone. This study aimed to evaluate the relationship between dental caries and jawbone trabeculation during the growth and development processes in children using fractal dimension (FD) analysis. Materials and methods: A total of 120 patients were divided into three groups. The groups were determined as follows: group 1: 40 patients without deep dentin caries/apical rarefying osteitis, group 2: 40 patients with deep dentin caries/apical rarefying osteitis on the right or left sides, and group 3: 40 patients with deep dentin caries/apical rarefying osteitis on both the right and left side. Digital panoramic images of the selected patients were evaluated using FD analysis. Results: There was no statistically significant difference in the FD analysis among the groups. Age and sex factors were not found statistically significant in the in-group evaluation (p>0.05). In group 3, FD values of the right condyle (r= -0.42, p<0.05), right ramus (r= -0.37, p<0.05) and left ramus (r= -0.45, p<0.05) were negatively correlated with age. Conclusion: There is no relationship between tooth decay and trabeculation of the jawbone in children aged 8-13 years.

Comparative evaluation of various herbal extracts on biofilms of Streptococcus mutans and Scardovia wiggsiae: An in vitro study.

BACKGROUND: Owing to their strong antimicrobial properties, Helichrysum arenarium (HA), Anzer thyme (AT), and Stevia rebaudiana (SR) have been commonly used in medicine. AIM: This study aimed to evaluate antimicrobial activities of HA, AT, and SR against S. mutans and S. wiggsiae in biofilms formed on primary teeth. DESIGN: Fifty enamel samples were divided into two groups: mono-species biofilm and two-species biofilm. Each biofilm group was divided into five subgroups (n = 5): group 1, HA; group 2, AT; group 3, SR; group 4, CHX (positive control); and group 5, distilled water (negative control). Minimum inhibitory concentration and minimum bactericidal concentration were determined. The number of viable microorganisms was counted. The presence of microorganisms was examined using a scanning electron microscope, and mineral analysis was performed using energy-dispersive X-ray analysis. RESULTS: In the mono-species biofilm, CHX was significantly more effective against S. mutans than other groups (p < .001). Furthermore, HA, AT, and SR groups showed significantly lower colony counts of S. mutans than distilled water (p < .05). In the two-species biofilm group, AT, SR, and CHX were significantly more effective against S. wiggsiae than distilled water (p < .05). CONCLUSIONS: HA, AT, and SR have been suggested as effective natural alternatives to CHX against cariogenic bacteria.

Turkish version of the faces version of the Modified Child Dental Anxiety Scale (MCDASf): translation, reliability, and validity.

OBJECTIVES: To cross-culturally adapt of MCDASf into Turkish and to evaluate reliability and validity of the Turkish version of MCDASf using explorative factor analysis (EFA), confirmatory factor analysis (CFA), and receiver operating characteristic (ROC) analysis to form a less time consuming and easy to understand tool for measuring dental anxiety. MATERIALS AND METHODS: A total of 300 children (174 females, 126 males) aged 6-12 years who were recruited at the Department of Paediatric Dentistry in RTEU at the first visit participated in the present study. For the internal consistency reliability, Cronbach's alpha was calculated. Intraclass correlation coefficients (ICCs) were calculated for test-retest reliability (n=67). Construct validity was determined by comparing with the Venham Picture Test (VPT). The factor structure was examined using EFA. CFA was used for dimensionality. The cut-off points of the Turkish version of MCDASf were plotted using a ROC curve. RESULTS: The Turkish version of MCDASf showed high internal consistency (0.703) and an excellent ICC value (0.827). Good correlations were found between the global scores of MCDASf and VPT (r=0.632). Three factors were identified from EFA and verified with CFA. Discriminant validity was supported by high scores of females and younger children (p<0.05). The cut-off point was assigned as >24.50. The area under the ROC curve (AUC) was 0.921 (95% CI: 0.873-0.969). CONCLUSIONS: The Turkish version of the MCDASf is a reliable and valid scale that satisfied psychometric properties. CLINICAL RELEVANCE: The Turkish version of MCDASf is a usable tool for the measurement of dental anxiety among Turkish speaking children.

Child and parent preferences for the appearance of dentists with respect to personal protective equipment in paediatric dentistry.

BACKGROUND: Personal protective equipment (PPE) gained particular importance during the COVID-19 pandemic. AIM: To assess child and parent preferences for dentists' appearance concerning their PPE and to determine the relationship between the child and parent preferences. DESIGN: A total of 250 children aged 6-12 years and their parents were enrolled in the study. Standardized pictures with different sexes, attires, eye protectors, hair protectors, masks, and gloves were shown to children and their parents separately, and they were asked to choose their preferences. The dental anxiety of the children and their parents was determined using the MCDASf and MDAS, respectively. Decayed, missing, and filled tooth (DMFT) indices were employed for the children. RESULTS: Children and parents preferred a dentist of the same sex as themselves (p < .05). Anxious children preferred cartoon-printed attire, and children with low anxiety mostly preferred white coats (p = .001). Children who preferred colored coats had higher DMFT (p < .001). Statistically significant differences were found in the attire and glove preferences between children and parents (p < .001). CONCLUSIONS: The production of white and child-friendly fluid-resistant disposable gowns should be considered. PPE with colored or cartoon print was preferred under the influence of factors that could positively affect anxiety.

Validity and reliability of the Turkish version of the Child Perceptions Questionnaire 8-10.

BACKGROUND: A reliable measurement tool is needed to gain more knowledge about Turkish children's oral health status that affects the quality of life. AIM: To develop a translated version of CPQ8-10 into Turkish language and evaluate its reliability, validity, and reproducibility. DESIGN: The intra-class correlation coefficient (ICC) was used for the test-retest reliability in the 50 children. For the internal consistency, 418 children aged 8-10 years were evaluated using Cronbach's alpha Coefficient. Construct validity and discriminant validity were calculated using Spearman's correlation analysis, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was also employed. RESULTS: The mean CPQ8-10 score was 13.3 ± 9.2. The translated Turkish version of CPQ8-10 showed high test-retest reliability (ICC = 0.90) and internal consistency (Cronbach's alpha = 0.82). A statistically significant correlation was observed between the scores of the CPQ8-10 and oral health and overall well-being, which revealed good construct validity (r = 0.50; P < .001 and r = 0.47; P < .001, respectively). Seven factors identified from EFA were statistically verified using CFA. Discriminant validity was supported by significant differences between CPQ and OHIS scores (P < .001). CONCLUSIONS: The translated version of CPQ8-10 to the Turkish language is reliable, valid, and reproducible for use in the Turkish culture in this age group.

Can lavender oil inhalation help to overcome dental anxiety and pain in children? A randomized clinical trial.

Aromatherapy with essential oils can be used to relieve children. The aim of this study was to evaluate the correlations between psychological and physiologic findings after lavender oil inhalation among children assigned to undergo tooth extraction. A total of 126 children aged between 6 and 12 years were enrolled in the study. The groups were randomly divided into control and lavender groups. The lavender group inhaled 100% lavender oil for 3 min before the interventions, the control group received no prior application. Psychological assessments were made using face image scale (FIS), Face, Legs, Activity, Cry, Consolability (FLACC) and Wong-Baker pain rating scale (WBS). Physiologic changes were assessed using vital signs evaluations. All parameters were noted prior to applications, after inhalation, anesthesia injection, and tooth extraction. The lavender group showed significant lower anxiety and pain scores after tooth extraction (p < 0.05). Significantly lower levels of blood pressures and a significant pulse rate drop were found after inhalation in the lavender group. A statistically significant increase in heart rate was observed after anesthesia injection and tooth extraction in the control group (p < 0.05).Conclusion: Lavender oil can be preferred as a treatment of choice in routine pediatric dentistry.Trial registration number: NCT04115891 (Lavender Oil Inhalation Help to Overcome Dental Anxiety Among Children)What is Known:• Dental anxiety is the most common factor that causes children to have difficulty with the dentist and their parents during treatment.• Aromatherapy with essential oils can be used to relieve children.What is New:• Aromatherapy with lavender oil relieves the child by reducing the level of anxiety and facilitates dental treatment.• During surgical procedures such as local anesthesia and tooth extraction, lavender oil inhalation decreases pain levels of children.
