Knowledge of general dentists, endodontists and pediatric dentists about the management on dental traumas: a survey in turkey

Objective: The purpose of this study was to determine endodontists, pedodontists and general dentists’ knowledge of management of dental trauma. Material and methods: A web-based survey including 13 questions was prepared using Google forms, and a link to the survey was sent to the general dentists, endodontists and paediatric dentists via social media. The questionnaire asked for information regarding the age, gender, state of education, type of institution and knowledge levels about dental traumas. A total of 258 questionnaires were returned, and the One-Way Anova for practitioners' knowledge and the statistical analysis of the relationship between gender, vocational training and training by using Mann-Whitney U tests for participants. Results: As a result of statistical analysis,  although there was no statistical difference between pedodontists and endodontists in their knowledge levels, it was found that both occupational groups had higher knowledge level than general dentists (p = 0,0001). While there was a significant difference between practitioners  at university and oral and dental health hospital (p = 0.0001), there was no difference between practitioners  in university hospital and private office (p = 0.065). Conclusions: In conclusion, general dentists had knowledge of inadequate dental trauma management and the knowledge level of dentists working at oral and dental hospital  was lower.KeywordsDental Trauma; Knowledge Level; General Dentist; Endodontists; Pediatric Dentistry.

Comparative Evaluation of Oral Health Status in Healthy Children and Children with Autism Spectrum Disorder

Objective Autism spectrum disorder (ASD) is regarded a severe neuropsychiatric disorder. The objective of this study was to compare the status of the oral health between children with and without ASDs.

Methods A total of 95 children (44 with ASD and 51 without ASD) were included. dmft/DMFT (d/D: decay; m/M: missing; f/F: filling; t/T: teeth) scores and plaque data of all participants were recorded. Saliva Streptococcus mutans and lactobacilli load were determined using CRT bacteria.

Results Streptococcus mutans load was >105 CFU in 54.5% of the ASD group and 43.1% in the non-ASD group. Lactobacilli load was >105 CFU in 47.70% of the ASD group and 49.0% in the non-ASD group. There was no statistically significant difference in the S. mutans or lactobacilli loads between the ASD and non-ASD groups. A total of 83.1% of the ASD group had caries, with dmft = 3.25 and DMFT = 5.10. In the non-ASD group, 81.10% of patients had caries, with dmft = 3.10 and DMFT = 4.90; 38.6% of the ASD group and 29.4% of the non-ASD group had no clinical signs of periodontal disease.

Conclusion The examination of the amount of saliva S. mutans and lactobacilli at intervals with these patients will provide quantitative data to evaluate the effectiveness of oral health care.

Efficacy of different remineralization agents on treating incipient enamel lesions of primary and permanent teeth

Aims and Objectives:

The aim of this study was to compare the in vitro efficacy of different remineralization (RM) agents on RM of artificial caries by evaluating the density, light reflection, and the crystal size of the newly formed mineral in primary and permanent teeth.

Materials and Methods:

Caries-free primary and permanent molars were divided into seven groups (n = 20) and treated with: G1 – Deionized water, G2 – Colgate Cavity Protection, G3 – Sensodyne Rapid Relief, G4 – GC MI Paste Plus, G5 – Clinpro Tooth Creme, G6 – Clinpro 5000, and G7 – Sensodyne Repair and Protect. Lesion depths were evaluated using laser fluorescence (DIAGNOdent), and polarized light microscopy (PLM), and the minerals were evaluated using X-ray diffractometry (XRD).

Results:

The highest decrease in laser fluorescence readings was observed in G6 for both primary and permanent teeth. No significant difference was observed between G2, G4, G5, and G6 in permanent teeth and G4 and G6 in primary teeth (P > 0.05). In PLM analyses, lesions depths were found to be lower in G6 compared to the other groups. No significant difference was observed between G2, G4, and G6 (P < 0.05). XRD evaluation showed that the newly formed mineral in G6 was denser and highly crystallized compared to the other groups.

Conclusion:

This in vitro study demonstrated that Clinpro 5000 is more efficient in remineralizing incipient enamel lesions compared to the other agents tested.

Fracture Resistance of Incisal Fragments Following Reattachment With Different Techniques in Simulated Crown Fractures

Introduction: The aim of the present study was to evaluate and compare the effect of acidetching and Er, Cr:YSGG laser treatment before the reattachment of incisal fragments in coronal fractures of permanent incisor teeth. Methods: Sixty-six sound human maxillary incisors were randomly divided into 3 groups (n=22). Teeth were embedded in self-cure acrylic resins by leaving one-third of the crowns out, and uncomplicated crown fractures were obtained using an Instron testing device. The fragments were reattached using 3 different procedures and a hybrid resin composite (Z250): Group I: Acid etching + Prime & Bond NT; Group II: Er,Cr:YSGG + Prime & Bond NT; Group III: Er,Cr:YSGG + Acid etching + Prime & Bond NT. The percentages of shear bond strengths were determined by comparing fracture strengths of sound and reattached teeth for 3 groups. All data were analyzed statistically with Kruskal-Wallis H test. Results: Mean fracture strengths of the reattached fragments were between 51.02% and 62.93% of that of the sound teeth in all groups. Group I had significantly higher percentages of shear bond strength values (P<0.05) when compared to group II and group III. No significant difference (P>0.05) was found between group II and group III. Conclusion: The findings of the present study show that Er,Cr:YSGG laser irradiation prior to the reattachment of incisal fragments has a negative effect on fracture strength.
