The Equality of Keywords of Journal of KAPD with Medical Subject Headings
Kim, Eunhee ; Kim, Ahhyeon ; Shim, Younsoo ; Ahn, Eunsuk ; Jeon, Eunyoung ; An, Soyoun ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 43, issue 2, 2016, Pages 123~128
DOI : 10.5933/JKAPD.2016.43.2.123
The purpose of this study is to analyze the equality between keywords used in the Journal of the Korean Academy of Pediatric Dentistry and medical subject headings (MeSH). A total of 4,353 English keywords in 1,165 papers from 1998 to 2014 were eligible for this study. We classified them according to equality to MeSH. We assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. 24.9% of total keywords were completely coincident with MeSH terms, 75.1% were not MeSH terms. The results show that the accordance rate of keywords with MeSH terms in the Journal of the Korean Pediatric Dentistry is at a low level. Therefore, there is a need for authors to understand MeSH more specifically and accurately. Use of proper keywords aligned with the international standards such as MeSH is important to be properly cited. Authors should pay attention and be educated on the correct use of MeSH as keywords.

The purpose of this study is to examine the sealing effect and efficiency of root canal filling MTA (Endoseal, Endoseal MTA). A total of 106 extracted single rooted teeth were used and classified with group AH (AH-26), group PR (ProRoot MTA), group ES (Endoseal) and group EM (Endoseal MTA) depending on filled sealers. Time was measured in each group when sealers were filled. The groups were divided into subgroup A and subgroup B. The sealing of root canal walls and penetration of sealer in the dentinal tubule were evaluated, respectively. According to the results, the sealing of root canal walls and dentinal tubule penetration of root canal filling MTA were inferior to AH-26 (p < 0.05). When compared with ProRoot MTA, however, there was no significant difference in sealing of root canal walls (p > 0.05), but dentinal tubule penetration was high (p < 0.05). Working time was shorter in root canal filling MTA than ProRoot MTA and AH-26 (p < 0.05). In conclusion, root canal filling MTA has lower root canal sealing effect than resin-based sealer, however, when in MTA needed root canal filling, it could be an effective alternative.

Special Health Care Needs (SHCN) patients need regular follow-up because of high incidence and severity of oral disease. The aim of this study was to evaluate the dental treatment outcomes of SHCN patients according to follow-up patterns. SHCN patients who were treated under general anesthesia (GA) at Kyung Hee University Dental Hospital from 2006 to 2014 were included in this study. The final samples comprised of 53 patients that were divided into regular (33 patients) and irregular (20 patients) follow-up groups according to their follow-up patterns. The type of dental treatment after GA during the follow-up periods were compared. In the irregular group, aggressive treatment including endodontic, prosthetic treatment, and extraction were predominant, compared with the regular group (p < 0.05). In addition, all patients who had dental treatment under GA in follow-up periods were in the irregular group (p < 0.05). In conclusion, the results of this study provide the importance of regular follow-ups with SHCN patients and emphasize responsibilities of dentists for educating patients and their guardians.

The purpose of this study was to evaluate the relationship between obesity and dental caries in young children. The subjects were 769 children aged 3 to 6 years, in Iksan, Korea. Body mass index (BMI) and decayed and filled primary teeth (dft) were recorded. Children were classified into four groups (underweight, normal, obese at risk, and obese) according to their BMI percentile. The data of 754 participants, excluding 15 underweight children, were analyzed. The mean dft index was 3.39. There were no significant differences in the number of caries according to gender. The dft index increased significantly with age, with a sharp increase between ages 4 and 5. Children in the obese at risk and obese groups had more caries than those in the normal group. However, there were no statistically significant differences in dft index values between BMI-categorized groups except in 3-year-olds. These findings suggest that there is no significant connection between obesity and dental caries in primary teeth.

The purpose of this study was to analyze photoplethysmographic waveforms from pulse oximeter using raw data of red and infrared light and investigate the reference values of parameters (Height, Width50, Maximum slope, Minimum slope, Area) for evaluating pulpal blood flow in maxillary central incisors with normal pulp vitality in children. The study was performed in 30 pediatric patients, aged 7-16 years old, using pulse oximeter (MEKICS Co., Ltd, Korea) combined with a custom-made sensor. The raw data was obtained and recorded by custom-made software and analyzed by LabChart (v.7.3, ADInstruments, Germany) offline. In this study, we analyzed photoplethysmographic waveforms from pulse oximeter applied to maxillary central incisor for assessment of pulpal blood flow and suggested several reference values of young permanent maxillary central incisor with normal pulp. On average, the waveform of red light was higher, stiffer and wider than that of infrared light. Future studies about reference values for other normal teeth and the teeth with impaired pulp vitality are needed.

There is no genetic activity information with the functions of dental pulp and periodontal ligament in human. The purpose of this study was to identify the gene-expression profiles of, and the molecular biological differences between periodontal ligament and dental pulp obtained from human permanent teeth. cDNA microarray analysis identified 347 genes with a fourfold or greater difference in expression level between the two tissue types 83 and 264, of which were more plentiful in periodontal ligament and dental pulp, respectively. Periodontal ligament exhibited strong expression of genes related to collagen synthesis (FAP), collagen degradation (MMP3, MMP9, and MMP13), and bone development and remodeling (SSP1, BMP3, ACP5, CTSK, and PTHLH). Pulp exhibited strong expression of genes associated with calcium ions (CALB1, SCIN, and CDH12) and the mineralization and formation of enamel and dentin (SPARC/SPOCK3, PHEX, AMBN, and DSPP). Among these genes, SPP1, SPARC/SPOCK3, AMBN, and DSPP were well known in dental research. However, the other genes are the newly found and it may help to find a good source of regenerative therapy if further study is performed.

This study was performed to compare the shape and dimension of anterior zirconia crowns to other pediatric crowns using a three-dimensional scanner to investigate adequate amount of tooth preparation. Primary central and lateral anterior zirconia crowns, stainless steel crowns and celluloid strip crowns were scanned by a three-dimensional scanner. Outer and inner surfaces of zirconia and stainless steel crowns, and outer surface of celluloid strip crowns were analyzed. In outer scanned images, all sizes of central and lateral size 1 zirconia crown had the largest labiolingual diameter among the three crowns. In inner scanned images, zirconia crown`s mesiodistal diameter was 0.7-1.0 mm smaller and crown length was approximately 1 mm shorter than those of stainless steel crowns. Zirconia crown`s labiolingual diameter was larger in central crowns whereas it was smaller in lateral crowns than that of stainless steel crowns. Recommended preparation required for zirconia crown is incisal 2.5-3.0 mm, mesiodistal 1.5-2.0 mm, labial 0.5-1.0 mm. Cingulum should be trimmed parallel to the long axis. No more lingual reduction is needed in central incisors whereas additional 0.5 mm reduction is suggested in lateral incisors.

Early loss of a primary second molar can cause mesial drift or tilting of the permanent first molar. We present a case of the early loss of the mandibular primary molars in a 5-year-old girl. The patient required extraction of the mandibular left primary first and second molars due to folliculitis on the successors. A flexible denture was used for eruption guidance of the permanent first molar and the recovery of masticatory function simultaneously.

Triple tooth is rare in primary dentition; it is the abnormal fusion of three teeth. There are a few reports of double teeth, but triple teeth are rare. These multiple teeth create several clinical problems, not only esthetic problems but also a high caries susceptibility, congenital missing permanent tooth germ(s), orthodontic problems, and periodontal problems. They also make it difficult to perform pulp treatment because of the complex tooth structure. A 1-year 7-month-old male underwent a partial pulpotomy with mineral trioxide aggregate (MTA) when pulp exposure caused by deep caries occurred at a maxillary anterior triple tooth in the first case. The second case was a 1-year 9-month-old male presenting with a fracture line at a mandibular anterior triple tooth. After removing the fractured fragment, a pulpectomy was performed at the remaining primary lateral incisors. Specific complications were not observed during 24 and 6 months of follow-up, respectively.

Root fracture is defined as a fracture involving the dentin, cementum, and pulp. Most fractures occur in the maxillary anterior teeth between the ages of 11 and 20 years old. The treatment for root fracture in permanent teeth involves the reduction and fixation of the displaced coronal segment. When signs of pulp necrosis or inflammatory root resorption are present, root canal therapy should be performed. Since most apical fragments maintain pulp vitality, root canal therapy is typically limited to coronal fragments. However, it`s too difficult to achieve a proper apical stop on coronal fragment. Intentional replantation involves performing root apex treatment outside the mouth after intentional extraction of the tooth in a controlled environment and then replanting it. The objective is `perfect` root canal therapy. Intentional replantation may be used in cases of failed typical root canal therapy, problematic endodontic retreatment due to the existing restoration or a calcified root canal, and when apical surgery is contraindicated because of a lack of reasonable approaches. In this case, intentional replantation was carried out to treat a horizontal root fracture in a maxillary central incisor with a calcified root canal due to previous trauma. We achieved a clinically and functionally satisfactory result.

Irritation fibroma is a common hyperplastic lesion of the oral mucosa that can occur in response to chronic irritation or trauma. This report presents an unusual case of irritation fibroma associated with ectopic eruption of the maxillary left central incisor in a patient with Angelman syndrome. Considering the patient`s medical history and cooperative ability, excisional biopsy under intramuscular sedation using midazolam was performed. The patient exhibited successful healing without lesion recurrence. It is important to perform histopathological examination followed by excisional biopsy, because other benign or malignant tumors may mimic the clinical appearance of an irritation fibroma.

In recent decades, dental erosion has received a considerable amount of attention with a steady increase of the prevalence. However, the awareness of this matter in our society, including dentistry is still lacking. Dental erosion is an irreversible loss of dental hard tissue leading to a complex condition. To prevent detrimental effects, it is important to detect conditions as early as possible and inhibit progression. In children and adolescents, early intervention is more important than in adults. As dental erosion is a multifactorial condition, dentists need to fully understand the phenomena and do systematic oral examination with thorough history taking for early diagnosis. When the main etiological factor is detected, it is necessary to make an effort to eliminate it and stop progression of the lesions with preventive measures. Restorative treatment should not be started unless substance loss reaches a certain level. Once the decision is made for treatment, care must be taken to choose the least invasive method.
