Retrospective evaluation of traction time for impacted dilacerated maxillary central incisors in mixed dentition

PURPOSES

This study aimed to contribute to understanding the factors affecting the time of traction treatment of impacted dilacerated maxillary central incisors.

METHODS

This retrospective study included children aged 8 - 11 years with a history of trauma, who applied to the pediatric dentistry clinics of Marmara University, School of Dentistry, between December 2013 and December 2019, and were treated for unilateral impacted dilacerated maxillary upper central incisors. Children's age, sex, digital panoramic radiographs, cone-beam computed tomography, and intraoral photographs were retrieved from electronic dental health records. The effects of children's age, sex, the direction of impacted teeth, distance of the teeth to the top of the alveolar crest, and root dilaceration level on traction time were analyzed by Mann-Whitney U test and Spearman's rank correlation coefficient test.

RESULTS

The inverse position of the incisors significantly increased the traction time (P = 0.012). However, the traction time did not differ according to the sex of the children (P = 0.707) or the level of root dilaceration (P = 0.429). No correlation was observed between the traction time and the age of children (P = 0.644) or the distance of the incisors from the top of the alveolar crest (P = 0.397).

CONCLUSIONS

In cases of the forced eruption of for the impacted dilacerated maxillary central incisors, the direction of the teeth should be evaluated when deciding on the treatment plan, as it may affect the treatment time.

Dental Caries, Dental Erosion and Periodontal Disease in Children with Inflammatory Bowel Disease

Background: There is reportedly a higher prevalence of dental caries and periodontal disease in adults with inflammatory bowel disease (IBD) than in healthy adults. Similar data for children are lacking in the literature. We aimed to evaluate the prevalence of dental erosion, dental caries, and periodontal disease in children with IBD. Methods: This was a cross-sectional comparative study. Using the established criteria of the World Health Organization, oral investigations and detailed questionnaires that covered nutritional habits were completed by the same pediatric dentist for 32 patients with IBD, aged 11 to 18 years (15.53 ± 2.00), and 32 healthy controls. Results: The decayed, missing, and filled tooth index showed no significant difference between the groups (p = 0.072). The frequency of consumption of salad, lemon gum, candy and sweetened milk was significantly higher in the control group (p = 0.041, 0.012, 0.001, and 0.001, respectively) than in the IBD group. No dental erosion was observed in the IBD group. Oral mucosal history determined that 20/32 patients with IBD (62.5%) had at least one oral extraintestinal manifestation. Despite no significant differences in plaque scores between the two groups, the gingival evaluation showed a much higher mean value of gingival index scores in the IBD group than in the control group (p = 0.003). Conclusion: Although the number of patients included in the study is small, we can conclude that oral extraintestinal manifestations and periodontal disease are more prevalent in paediatric patients with IBD than in healthy populations.

Children's drawing as a measurement of dental anxiety in paediatric dentistry

BACKGROUND

Drawings can be used as a method of communication that represents an individual's self-concept, anxiety, attitude or conflict.

AIM

The purpose of this study was to evaluate children's drawing as a measure of dental anxiety in a dental setting.

DESIGN

Seventy-eight children, aged 6-12 years, were enrolled in this study. Pulp therapy and/or restorative treatment was performed during the first therapeutic session for all participants. Sound, Eye and Motor (SEM) and Frankl scales were used as an objective assessment of behaviour during treatment. After the treatment session, the children were instructed to draw a picture of a person at a dental clinic. Children's drawings were scored by a paediatric dentist and a psychologist using Child Drawing: Hospital (CD: H) scale and emotional indicators of Human Figure Drawings (HFD). The findings were compared with Frankl and SEM scores.

RESULTS

There was a significant negative correlation between Frankl and CD: H scores (P = .017), and a significant negative correlation was found between HFD and Frankl scores (P = .048).

CONCLUSION

Drawings can reveal a considerable amount of information about children's emotional status, and children's drawing can be a useful non-verbal self-report measure to evaluate anxiety in a paediatric dental setting.

Resin infiltration technique and fluoride varnish on white spot lesions in children: Preliminary findings of a randomized clinical trial

Aim

To clinically assess the efficacy of resin infiltration versus fluoride varnish for arresting white spot lesions (WSLs) on permanent teeth in children.

Subjects and Methods

Among the children referred to the our University, Faculty of Dentistry, Department of Pediatric Dentistry, 23 aged between 8-14 with 81 anterior WSLs were included in the study. The participants were randomly assigned to either the resin infiltration group or the fluoride varnish group. WSLs were assessed using a laser fluorescence device (DIAGNOdent pen, Kavo, Germany) and were characterized at baseline, immediately following resin infiltration application and at a 6-month follow-up. For the statistical analyses, the IBM SPSS Statistics 22 (IBM SPSS, Turkey) program was used to assess the findings of the study.

Results

Participant retention was 100% at 6 months. There was no significant difference between the two groups when baseline DIAGNOdent (DD) values were compared (P > 0.05). The reduction in 6-month follow-up DD values were statistically significant in both groups relative to baseline values. The 6-month values of the resin infiltration group were statistically lower than those of the fluoride varnish group (P = 0.028, P < 0.05).

Conclusions

Resin infiltration and fluoride varnish are clinically feasible and efficacious methods for the treatment of anterior WSLs. The inhibition of caries progression by resin infiltration should now be considered an alternative to fluoride treatment.

The Internet versus pediatricians as a source of infant teething information for parents in Turkey

OBJECTIVES

Parents are increasingly searching the Internet to gather information about their children's health care. This study compared infant teething information obtained from publically employed pediatricians in Istanbul with that obtained from different Turkish websites (parenting, health, professional, news and commercial).

METHODS

This study had two parts. The first part used a descriptive design, with two checklists to assess the quality and comprehensiveness of the teething-specific content on 62 parenting or health websites. The second part was a cross-sectional study of 75 pediatricians at public hospitals who completed a structured self-administered questionnaire.

RESULTS

In total, 54 websites (87.1%) described infant teething as a normal developmental process. The lists that were found on the websites identified the most frequent signs of infant teething as fever and drooling/perioral rash. The most frequent management strategies were chewing non-chilled and chilled objects. For teething problems, some pediatricians recommended teething rings and oral benzocaine, while 23 pediatricians recommended nothing.

CONCLUSIONS

Parents should be informed by health professionals, especially regarding specific treatment strategies.

Microhardness evaluation of enamel adjacent to an improved GIC sealant after different enamel pre-treatment procedures

AIM

This in vitro study was carried out to evaluate the microhardness of enamel adjacent to a glass ionomer cement (GIC) with high fluoride content used as a sealant (Fuji Triage, GC Corp., Japan) after laser, bur or air abrasion treatment procedures.

STUDY DESIGN

200 freshly extracted non-carious human molars were divided into 10 experimental groups according to the enamel pre-treatment method: A air abrasion (Mach 4.1 Kreativ Inc., USA); AP, Air abrasion + conditioning with 20% polyacrylic acid (GC cavity conditioner); L, Er,Cr:YSGG laser application (Waterlase, Biolase Technology, Inc., San Clemente, USA); LP, Er,Cr:YSGG laser application and fissure conditioning; B, ameloplasty carried out with a diamond bur especially designed for preparing fissures (Komet #8833); BP, ameloplasty + fissure conditioning; P, application of 20% polyacrylic acid and all fissures sealed with GIC; C, no fissure treatment, the material was applied directly to the fissures (control); R, application of 37% orthophosphoric acid and fissures sealed with a resin-based sealant (Fissurit; Voco, Germany) (control); N, no treatment (control). Half of each group of teeth were left in artificial saliva for one month and the rest for three months. The teeth were then sectioned and microhardness was measured using a Vickers test apparatus. Kruskal-Wallis, Mann-Whitney U and Dunn's multiple comparison tests were carried out (5% significance).

RESULTS

After one month results regarding hardness at the base and lateral walls of fissures were significantly higher in groups A, AP, L, LP, B, BP, P and C than in groups R and N (p<0.01), but no difference was seen between the treatment procedures. The results after three months produced similar findings with evenly increased values for all groups.

CONCLUSION

The results of this study showed that the tested GIC with a higher fluoride content seemed to improve the enamel hardness of the fissure enamel and could be regarded as an alternative material in cases where resin sealant applications are questionable.

In vitro evaluation of microleakage under a glass ionomer surface protector cement after different enamel treatment procedures

AIM

The aim of this in vitrostudy was to evaluate the microleakage of a glass-ionomer surface-protector cement (GC Fuji Triage) placed onto the fissure surfaces of extracted human molars prepared using six different treatment procedures.

METHODS

Ninety-six extracted non-carious human molar teeth were divided into five enamel treatment groups: (Gp1) air-abraded (Micadent II, Medidenta); (Gp2) air-abraded and conditioned with 10% polyacrylic acid (GC dentin conditioner); (Gp3) prepared by a bur designed for enameloplasty (#8833 Komet); (Gp4) prepared with a bur and conditioned; (Gp5) conditioned; and (Gp6) no treatment (control). The teeth were then sealed with GC Fuji Triage. The teeth were thermocycled and left in distilled water or artificial saliva for one week, coated twice with nail varnish, and stained in a dye. They were sectioned and scored for microleakage.

RESULTS

All groups showed microleakage. Samples that were kept in saliva had better results than those that were kept in distilled water (P<0.05). Samples conditioned before the treatment were also better than non-conditioned groups (P<0.05). In distilled water and artificial saliva, the range of the groups was, from the best, Gp2<Gp4<Gp5=Gp3<Gp1=Gp6 and Gp4<Gp2<Gp3<Gp5<Gp1<Gp6, respectively.

CONCLUSIONS

This in vitrostudy showed that the microleakage under the GIC material could be improved after treatment procedures such as conditioning, and/or air abrasion, and/or ameloplasty.

Selectin adhesion molecules in Behçet's disease

OBJECTIVES

The pathogenesis of Behçet's disease (BD) is closely related to endothelial cells, leucocyte functions and autoimmunity. The aim of this study was to investigate circulating selectin adhesion molecules, which are known to play a significant part in the immune response especially by regulating interactions of the leucocytes with endothelium, in BD.

METHODS

Plasma E-, L-, and P-selectin concentrations were evaluated in 11 patients with widespread BD (group I), 10 cases with merely mucocutaneous involvement (group II) and 15 age and sex matched healthy control subjects. The patients were newly or previously diagnosed cases not taking any drug for BD.

RESULTS

Plasma concentrations of all selectins were significantly higher in group I compared with group II. E-selectin and P-selectin were significantly increased in each subgroup of patients compared with the healthy controls. L-selectin concentrations were higher than the controls only in group I.

CONCLUSIONS

Increases in the selectins in BD may be a direct consequence of the leucocyte, endothelium and platelet activations observed during the disease process. However, abnormal/increased selectin expression to various triggers should also be considered. More prominent increases in patients with extensive disease suggest that circulating selectin concentrations are related to disease severity.
