1.Analysis of Factors that Affect the Follow-up Pattern after Dental Treatment under Conscious Sedation in Children
Journal of Korean Academy of Pediatric Dentistry 2018;45(3):324-333
Children need regularly dental check-ups after dental treatment because there are a lot of changes of oral conditions such as tooth exfoliation and eruption, occlusion, and recurrence of dental caries. The purpose of this study is to determine the factors that affect the follow-up pattern after dental treatment under conscious sedation.Patients who were treated under sedation at the department of pediatric dentistry of Ewha Womans University Mokdong Hospital from 2009 to 2013 were included in this study. The final samples comprised of 562 patients that were classified into 4 groups according to the number of visits during 3 years. The chi-square test was used to determine the factors affecting regular follow-up.There were statistically significant differences between each treatment groups and factors such as the change of doctor, overall treatment time, the number of treated teeth under sedation, restorative treatment, minor operation, and preventive treatment (p < 0.05).This study identified factors that affect regular follow-up after dental treatment under conscious sedation. It is recommended to educate the importance of regular check-ups to parents who are less likely to return.

Noonan syndrome is characterized by distinctive facial features, short stature, and congenital heart disease. It is a congenital genetic disorder with a prevalence of between 1/1,000 and 1/2,500 in both genders.An 11-year-old boy with Noonan syndrome visited the hospital with an ectopically positioned tooth. A pulmonary stenosis was diagnosed and his growth and development were delayed. In many cases of this diseases there is obvious hemostasis, which he was not experiencing. His facial appearance showed characteristic features of Noonan syndrome. The patient showed a dental class II relationship, labioversion of the upper anterior teeth, and a shallow overbite. Radiographic examination revealed that the upper right canine was ectopically positioned, which led to root resorption of the upper right lateral incisor. A lateral cephalometric radiograph revealed a craniofacial pattern that was within normal limits. Surgical opening and button attachment on the impacted upper right canine were performed and traction was applied on the impacted tooth using a removable appliance.This patient was mildly affected by Noonan syndrome and showed some dental problems. However, few studies have reported the oral characteristics of Noonan syndrome despite its high incidence. Thus, this case report describes the oral features and management of Noonan syndrome.

Purpose:
This study aimed to evaluate the clinical outcomes of a single type of narrowdiameter implant (NDI) by investigating its survival rate and peri-implant marginal bone loss (MBL). In addition, variables possibly related to implant survival and MBL were investigated to identify potential risk factors.
Methods:
The study was conducted as a retrospective study involving 49 patients who had received 3.0-mm diameter TSIII implants (Osstem Implant Co.) at Seoul National University Dental Hospital. In total, 64 implants were included, and dental records and radiographic data were collected from 2017 to 2022. Kaplan-Meier survival curves and a Cox proportional hazard model were used to estimate the implant survival rate and to investigate the effects of age, sex, jaw, implant location, implant length, the stage of surgery, guided bone regeneration, type of implant placement, and the surgeon’s proficiency (resident or professor) on implant survival. The MBL of the NDIs was measured, and the factors influencing MBL were evaluated.
Results:
The mean observation period was 30.5 months (interquartile range, 26.75–45 months), and 6 out of 64 implants failed. The survival rate of the NDIs was 90.6%, and the multivariate Cox regression analysis showed that age was associated with implant failure (hazard ratio, 1.17; 95% confidence interval, 1.04–1.31, P=0.01). The mean MBL was 0.44±0.75 mm, and no factors showed statistically significant associations with greater MBL.
Conclusions
NDIs can be considered a primary alternative when standard-diameter implants are unsuitable. However, further studies are required to confirm their long-term stability.
