Purpose: Small for gestational age (SGA) is confusingly defined as birth weight (BW) either below 3rd percentile or 10th percentile for infants. This study aimed to compare postnatal catch-up growth between SGA groups according to different definitions. Methods: Data of 129 infants born with BW below the 10th percentile and admitted to Korea University Anam Hospital and Ansan Hospital were retrospectively reviewed. Height and weight were measured at 6, 12, and 24 months. Results were compared between group A (BW: <3rd percentile) and group B (BW: 3rd–10th percentile). Results: Group A included 66 infants and group B included 63. At age 6 months (n=122), 62.9% of group A and 71.7% (P=0.303) of group B showed catch-up growth in weight. At 6 months (n=69), 55.9% of group A and 80.0% of group B (P<0.05) showed catch-up growth in height. At 12 months (n=106), 58.5% of group A, and 75.5% (P=0.062) of group B showed catch-up growth in weight. At 12 months (n=75), 52.8% of group A and 64.1% of group B (P=0.320) showed catch-up growth in height. Up to age 24 months, 66.7%/80.0% in group A and 63.6%/80.0% in group B showed catch-up growth in weight/height. Conclusion: Despite different definitions, there were no significant differences between the two SGA groups in postnatal catch-up growth up to age 24 months, except for height at 6 months. Compared to infants with appropriate catch-up growth, low gestational age and BW were risk factors for failed catch-up growth at 6 months.

허지선,황지혜,이은희,부윤정,최병민,홍영숙 대한신생아학회 2016 Neonatal medicine Vol.23 No.3

Peritoneal dialysis can be considered renal supportive therapy, even in an extremely low birth weight infant with acute kidney injury not responding to general supportive measures. Although there have been several reports of successful peritoneal dialysis in extremely low birth weight infants, general practice guidelines and commercially available optimal peritoneal dialysis catheters have not been introduced. We report a successful case of peritoneal dialysis in an extremely low birth weight infant born at 25 weeks gestational age, with birth weight 790 g, with uncontrollable metabolic acidosis, hyperkalemia, progressive azotemia and continued anuria.

Recently, use of natural medicine is getting more attention, and some of them are believed to be effective in the treatment of periodontitis. Among them, the seeds of safflower(Carthamus tinctrorius L.) have been proven to be effective through its use in bone diseases such as fracture and osteoporosis. During the last few years, studies using the seeds of safflower gown in Korea have been active, and it has been reported that safflower seed extract increase the proliferation and the alkaline phosphatase(ALP) activity of human periodontal ligament fibroblast(hPDLF), osteoblast, and that they promote the mineralization process. In animal studies, when safflower seed extract were administered orally new bone formation was promoted. Recently, in an effort to find out the most effective osteogenic components, among many components of the safflower seed, various safflower seed fraction extracts were obtained by multistep extraction of the safflower components using various solvents. Among these, saf-M-W fraction extracted by methanol and water was most effective in increasing osteogenic potential of osteoblasts. In this study, the effect of safflower seed fraction extract, saf-M-W, on the growth and differentiation of hPDLF and MC3T3-E1 cell was investigated. The toxicity of saf-M-W on both cells was measured using M'IT(3-(4,5dimethylthiazol-2-y1)-2,5-diphenyl tetrazolium bromide) test, and ALP activity was measured using the colorimetric assay of hPDLF. In addition, in MC3T3-El cells, the expression of ALP, bone sialoprotein(BSP) mRNA was observed using Northern blot, and the mineralized nodule formation Was observed using von Kossa stain and phase-contrast microscope. 1. In concentrations below $10{\mu}g/ml$, saf-M-W didn't show any toxicity on hPDLF and MC3T3-El cell. 2. The change in saf-M-W concentration had no effect on the ALP activity of hPDLF. 3. In MC3T-E1 cells, mRNA expressions of ALP and BSP were greater in the experimental group treated with $10{\mu}g/ml$ concentration of saf-M-W compared with the control group. 4. In MC3T3-El cells, abundance of mineralized nodules were formed in the experimental group treated with $10{\mu}g/ml$ Concentration of saf-M-W, while no mineralized nodule was formed in the control group. These results suggest that safflower seed fraction extract, saf-M-W. didn't show any toxicity on hPDLF and MC3T3-E1 cell at concentrations below $10{\mu}g/ml$ and effectively enhanced the differentiation and osteogenic potential of MC3T3-El cell.

This is a case report of combined sinus floor augmentation and alveolar ridge augmentation using a titanium mesh simultaneously performed with extraction of an ankylosed maxillary molar. An 18-year-old male presented with discomfort in the upper right molar. The maxillary right first molar was diagnosed with chronic apical periodontitis, ankylosis, and secondary dental caries. It was determined as hopeless prognosis due to the extensive secondary caries so we planned extraction of the tooth. Due to the pneumatization of the maxillary sinus and the vertical defects of the alveolar ridge, the bone dimension was insufficient for future implant placement. Sinus floor augmentation and alveolar ridge augmentation were performed simultaneously with extraction. Buccal flap was elevated for approach to the ankylosed root and the sinus. Piezosurgery was used for atraumatic removal of ankylosed tooth and the sinus window formation without the Schneiderian membrane perforation. Demineralized bone matrix and bovine bone mineral were grafted into the sinus and on the defected ridge. The sinus window was covered with a collagen membrane and a titanium mesh was installed at the ridge. Primary closure was achieved with buccal advanced flap and palatal rotational flap. Though there was titanium mesh exposure during the healing process, but sufficient bone formation was achieved. And the implant placement and the restoration procedures were successfully completed.

Since 2013, adults aged over 20 can receive national health insurance scaling once a year in South Korea. In this study, we analyzed the usage status of national health insurance care service for periodontal disease in 2010-2018 by using Healthcare big data of the Health Insurance Review and Assessment Service. The increase rate of the dental care users was very high at 7.8 and 11.2% in 2013 and 2014, respectively. These are higher than the increase rate of all medical institution users, which is between -1.7 and 3.7%. In 2017, the rate of dental use was 44.4%, which has increased more than 10% compared to 2012. Percent receiver of national health insurance scaling was 19.5% in 2017. The 20s had the highest rate of 23.2%. The rate decreased with age. Based on these results, it can be evaluated that the expansion of national health insurance coverage for scaling improves accessibility to dental care. A more long-term assessment of the effect of periodic dental examination and scaling on reducing the prevalence of periodontal disease is needed. National health insurance coverage should be extended to oral hygiene education and supportive periodontal therapy in order to prevent periodontal disease.

The purpose of the present study was to evaluate the clinical efficacy of guided tissue regeneration(GTR) using resorbable polylactic/polyglycolic copolymer(PLA/PGA) membrane in mandibular class II furcation involvement and to compare it to the clinical efficacy of only flap operation. Both procedures were conducted in 5 patients with class II furcation involvements. After 6 months of follow up, the probing pocket depth, clincial attachment level, bone probing depth, and radiographic changes were compared, and the following results were obtained: 1. GTR using PLA/PGA demonstrated a statistically significant reduction in probing pocket depth and bone probing depth, and the control group demonstrated a statistically significant reduction in bone probing depth. 2. The comparison between the experimental and control group failed to demonstrate statistically significant difference in clinical improvement, but more reduction in probing pocket depth and bone probing depth were observed in the experimental group. The probing pocket depth and the bone probing depth were $2.2{\pm}1.6mm$ and $2.4{\pm}1.1mm$ respectively in the control group, while they were $2.4{\pm}1.3mm$ and $3.0{\pm}1.2mm$ respectively in the experimental group. 3. Radiographic change was not detectable for the both groups during the 6 months of follow up. 4. Sites with deeper probing pocket depth at baseline examination showed greater amount of clinical improvement in both groups. Other clinical factors didn't have any significant effect on the treatment results. It is concluded that though there are some limitations, PLA/PGA membrane is effective for the treatment of mandibular class II furcation involvement.

We reviewed the current oral health status, the use of dental health services, and the factors that impede access to dental care for disabled people in South Korea and aimed to suggest the future direction of the dental community for establishing the right to oral health for the disabled people. Disabled people experienced more and faster teeth loss than non-disabled people due to the lack of proper oral hygiene management. The rate of not receiving proper dental prosthodontic treatment for the lost teeth in disabled people was higher than in non-disabled people. Economic factors, patient cooperation, and communication issues were the most important constraints on dental accessibility for the disabled. Many people with disabilities used dental clinics nearby, and some severely disabled people used special dental clinics for the disabled even if they were far. The current dental policy for the disabled people was limited to the provision of dental treatment on the oral care center for the disabled and reduction of the treatment fee. It would be a much more economical and efficient way to supply the prevention-oriented oral health management rather than to provide dental treatment such as prosthetic fabrication, which requires long time and high cost. It is necessary to educate dentists, dental hygienists, and dental students in order to strengthen the competency for the special care dentistry. The whole dental community and the government should make an effort together to establish for the equal right to oral health of the people with disability.

Foreign body aspiration and ingestion in dental clinic: a seven-year retrospective study

허지선,이남권,김기열,정서연,차정열,김기덕,박원서 대한치과마취과학회 2022 Journal of Dental Anesthesia and Pain Medicine Vol.22 No.3

Background: This retrospective study investigated the incidence rate of accidental foreign body aspiration and ingestion according to patient sex, age, and dental department. This study aimed to verify whether the incidence rate is higher in geriatric than in younger patients and whether it is different among dental departments. Methods: Accidental foreign body aspiration and ingestion cases were collected from electronic health records and the safety report system of Yonsei University Dental Hospital from January 2011 to December 2017. The collected data included patients’ age, sex, medical conditions, treatment procedures, and foreign objects that were accidentally aspirated or ingested. The incidence rate was calculated as the number of accidental foreign body aspirations and ingestions relative to the total number of patient visits. Differences depending on the patients’ sex, age, and dental department were statistically identified. Results: There were 2 aspiration and 37 ingestion cases during the 7-year analysis period. The male to female incidence ratio was 2.8:1. The incidence rate increased with age and increased rapidly among those aged 80 years or older. Seven of the 37 patients with accidental foreign body ingestion had intellectual disability, Lou Gehrig’s disease, dystonia, or oral and maxillofacial cancer. The incidence rate was highest in the Predoctoral Student Clinic and the Department of Prosthodontics. The most frequently swallowed objects were fixed dental prostheses and dental implant components. Conclusion: The incidence rate of accidental foreign body aspiration and ingestion differed according to patient sex, age, and dental department. Dental practitioners must identify high-risk patients and apply various methods to prevent accidental foreign body aspiration and ingestion in dental clinics. Inexperienced practitioners should be particularly careful.
