A retrospective evaluation of traumatic dental injury in children who applied to the dental hospital, Turkey

OBJECTIVE The purpose of this study was to analyze traumatic dental injuries in children visiting the dental hospital emergency department in Samsun of Turkey, in the period from 2007 to 2011. MATERIALS AND METHODS Data of age, gender, causes of dental trauma, injured teeth, type of dental injuries, the application period, the dental treatments, and traumatic dental injuries according to the seasons were obtained from the records at dental hospital. RESULTS Of all 320 patients with traumatic dental injury, 205 were boys and 115 were girls with a boys/girls ratio 1.78:1. Traumatic dental injury was observed more frequently in the 7-12 age groups: 52.5% in girls and 67.8% in boys. Falls are the major cause of traumatic dental injury in the age group 6-12 (51.4%). Sport activities are a common cause of traumatic dental injury in the 7-12 age group (34.2%). Patients visited a dentist within approximately 2 h (57.1%). The upper anterior teeth were subjected to trauma more frequently than the lower anterior teeth. The maxillary central incisors were the most commonly affected teeth, and the mandibular canins were the least affected teeth. In primary teeth, avulsion was the most common type of dental injury (23%); on the other hand, enamel fractures were the most common type of dental injury (30.6%) observed in permanent teeth. In the primary dentition, the most commonly performed treatments were dental examination and prescribing (70%). The most common treatment choices in permanent teeth were restoration and dental examination (49.7 and 15.8%, respectively). CONCLUSION The results of the study show that the emergency intervention to traumatized teeth is important for good prognosis of teeth and oral tissues. Therefore, the parents should be informed about dental trauma in schools, and dental hospital physicians should be subjected to postgraduate training.

A retrospective comparison of dental treatment under general anesthesia on children with and without mental disabilities

PURPOSE The purpose of this study is to determine the properties of the dental procedures performed on children with dental problems under general anesthesia and compared between the patterns of dental treatment provided for intellectual disability and non-cooperate healthy child. MATERIALS AND METHODS In this retrospective study, the records of patients between the ages of 4 and 18 who were treated under general anesthesia were evaluated. Patients were divided into two groups: Those with intellectual disability and healthy patients who had difficulty cooperating. A statistical analysis of the mean standard deviation was conducted with a focus on two factors: Age and dental treatment methods. RESULTS In this study, it was observed that restorative treatment and tooth extraction was generally higher in intellectual disability children than in their healthy children. When evaluating the health status of teeth, the value of decayed missing and filled teeth (dmf-t) was observed to be close in healthy and intellectual disability individuals in the 4-6 age groups; it was higher in individuals with intellectual disability in the 7-12 age groups. There was no significant difference in terms of periodontal treatment and fissure sealants in the 12-18 age groups. CONCLUSIONS By comparing the different patient groups who received dental treatment under general anesthesia, both the number of teeth extracted and DMF-T indices were higher in the disabled group. Therefore, especially more efforts should be made at encouraging these patients to visit the dentist earlier and receive primary preventive care.

Evaluation of the effect of food and beverages on enamel and restorative materials by SEM and Fourier transform infrared spectroscopy

Objectives To examine different types of restorative materials used in children as well as primary and permanent teeth enamel when affected by erosive foods. Materials and Method Buttermilk, fruit yoghurt, Coca‐cola, fruit juice, Filtek Z‐250, Dyract Extra, Fuji II LC, and Fuji IX and tooth enamel were used. Measurements were performed on 1‐day, 1‐week, 1‐month, 3‐month, 6‐month time periods by using ATR‐FTIR technique and surface of the specimens were examined with SEM. Results Permanent tooth showed the least change among human tooth samples when compared to restorative materials. Among filler materials, the most change was observed in Fuji IX. In terms of beverages the most changes on absorption peaks obtained from spectra were seen on the samples held in Coca‐Cola and orange‐juice. Conclusion The exposure of human enamel and restorative materials to acidic drinks may accelerate the degradation process and so reduce the life time of filler materials at equivalent integral exposure times longer than three months. Clinical Relevance Erosive foods and drinks having acidic potential destroy not only tooth enamel but also restorative materials. Microsc. Res. Tech. 77:79–90, 2014.

Effects of Er:YAG laser on bond strength of self‐etching adhesives to caries‐affected dentin

The erbium:yttrium–aluminum–garnet (Er:YAG) laser may be effective the bond strength of adhesive systems on dentine surfaces, the chemical composition and aggressiveness of adhesive systems in clinical practice. The purpose of this study was to evaluate the effects of the Er:YAG laser system with the bonding ability of two different self‐etching adhesives to caries‐affected dentine in primary molars. Ninety mid‐coronal flat dentine surfaces obtained from sound and caries‐affected human primary dentine were treated with an Er:YAG laser or a bur. The prepared surfaces were restored with an adhesive system (Xeno V; Clearfil S3) and a compomer (Dyract Extra). The restored teeth were sectioned with a low‐speed saw and 162 samples were obtained. The bond strength of the adhesive systems was tested using the micro‐tensile test method. The data were statistically analyzed. A restored tooth in each group was processed for scanning electron microscopy evaluation. The values of the highest bond strength were obtained from the Clearfil S3‐Er:YAG laser‐sound dentine group in all groups. (24.57 ± 7.27 MPa) (P > 0.05). The values of the lowest bond strength were obtained from the Xeno V‐Er:YAG laser‐sound dentine group in all groups (11.01 ± 3.89 MPa). It was determined that the Clearfil S3 increased the bond strength on the surface applied with Er:YAG laser according to the Xeno V. Microsc. Res. Tech. 77:282–288, 2014.

Evaluation of bond strength of self-etching adhesives having different pH on primary and permanent teeth dentin

Purpose The purpose of this in vitro study was to evaluate the dentin shear bond strength of 4 self-etching adhesives having a different pH on primary and permanent teeth dentin. Methods The occlusal enamel was removed from 60 freshly extracted third molar and 60 primary second molar human teeth, which were randomly separated into 4 groups (n = 15). Four adhesive systems were applied: G-Bond (GC Corporation, Tokyo, Japan, pH: 1.5), Futura Bond M (Voco, Cuxhaver, Germany, pH: 1.4), Adper Prompt L-Pop (3M/ESPE, St Paul, MN, USA, pH: 0.8), and Clearfil S3 Bond (Kuraray Medical, Tokyo, Japan, pH: 2.7) according to the manufacturers instructions. After the application of dentin bonding agents, a composite resin material (Z250 Restorative A2, 3M ESPE, St. Paul, MN, USA) for permanent teeth and a compomer resin material (Dyract Extra A2, Dentsply, Konstanz, Germany) for primary teeth was applied onto the prepared dentin surfaces. The data were obtained by using a universal test machine at a crosshead speed of 1 mm/min. Results The mean values were compared using Tukeys multiple comparison test. Although there was no difference between adhesives on the permanent teeth, Clearfil S3 adhesive showed higher bond (18.07 ± 0.58 MPa) (P>0.05). Lower bond strength values were obtained from primary teeth and especially G-Bond adhesive (9.36 ± 0.48 MPa) (P<0.05). Conclusions Self-etching adhesives with different pH and solvent types can be used successfully for permanent teeth dentin but adhesives with low pH did not provide greater shear bond strength values.

A retrospective study of nontraumatic dental condition-related visits to dental hospital emergency service

This study aims to evaluate patients with nontraumatic dental condition-related visits to the dental hospital emergency service as well as the associate factors. Between June 2007 and June 2011, automation-system based data from 147.840 patients 62.4% were males, 37.6% were females who were admitted to Samsun Dental Hospital Emergency Service in Turkey with nontraumatic dental conditions were retrospectively analyzed. Demographic characteristics of the patients, date and time of admission to the emergency service, the International Classification of Diseases-9 codes and treatment administered to the patients on admission were recorded. The most common complaints on admission were pulpal and periapical tissue diseases in 29.377 patients (74.0%). A total of 45.5% were admitted in out-of-hours emergencies, while 26% were admitted in working hours and 28.5% were admitted on weekends. Patients in the 19-30 age groups had the highest rate for admission in out-of-hours emergencies on weekdays. There was no significant difference in monthly admission rates among the patients. The number of patients who were admitted to emergency service was significantly lower. Our study results indicate that there is an insufficient demand for dental care in Turkish population. We suggest that the number of patients who are admitted to the dental hospital emergency service may be reduced by increased awareness of oral and dental care.
