Dental stress is suggested as a main reason for behavioral problems in dentistry, especially in children. Heart rate is a useful measure of dental stress. The purpose of the present study is to examine the effect of dental stress on children receiving restorative treatment under local anesthesia by using recently introduced a wrist-watch type heart rate monitoring device. Eighteen children with no previous dental experience, who needed dental treatment involving local anesthesia, were included in this study. In each session, heart rate was recorded. The largest increase was observed during local anesthesia and the highest values were recorded during preparation. However, no significant relationship was found between the measurements(p > 0.05). Regarding the number of visits, heart rate on the second session is significantly higher than the first session and the third session(p < 0.05). There was no significant different correlation between the first session and third session(p > 0.05). Based on the present study, children who have no previous dental treatment appeared to be more stressed at the second session and need at least 3 sessions to feel less stressed during dental treatment including dental injection.

The purpose of this study was to evaluate the skeletal and dentoalveolar effects of facemask therapy and to compare the anchorage of a bonded expander in patients with Class III malocclusion and different vertical skeletal patterns. Twenty subjects with Class III malocclusion were included in this study and were treated with a facemask and bonded expander. Based on the FMA, subjects were divided into two groups of 10 patients each: a high vertical group (HV; mean FMA
) and an average vertical group (AV; mean FMA
). Lateral cephalograms were taken and evaluated before and after treatment. In both groups, forward movement of the maxilla and backward rotation of the mandible were observed after treatment, with no statistical differences between the groups. Vertical skeletal variables increased in both groups, but the increase of FMA was significantly larger in the HV group than the AV group. Mesial movement of maxillary molars and proclination of maxillary incisors which indicate anchorage loss of bonded expander were observed in both groups, with no significant differences between the groups. In conclusion, facemask therapy resulted in effective maxillary protraction in both HV and AV groups. However, the open bite tendency was increased more in the HV group.

Interest in orthodontic treatment has increased. Consequently, the percentage of the orthodontic treatment in pediatric dentistry has also increased. Given this background, the purpose of this study was to analyze the characteristics and the trends of pediatric orthodontic patients of Chonnam National University Dental hospital. A total of 670 patients (349 male, 321 female) diagnosed with orthodontic problems during the period from January 1st, 2004 to December 31st, 2014, were analyzed. The number of pediatric orthodontic patients was high in January, February, July and August. When it comes to age, the percentage of the patients who were eighty-years old accounted for the largest age group with 19.6%, followed by seven-year, nine-year, ten-year, eleven-year, and six-year old age groups. Skeletal class 1 accounted for 48.1% of the total cases, followed by class 2 (28.7%) and class 3 (23.3%). Mesofacial type accounted for 65% of the total cases, followed by dolichofacial type (19.3%) and brachyfacial type (15.8%). The period of the first phase orthodontic treatment was steadily shortened from 30.4 months in 2004 to 11.5 months in 2013. The result of this study is expected to provide information of the pediatric orthodontic patients.

Early treatment is recommended for class III malocclusion in the primary dentition, though it is difficult to diagnose correctly. It was recommended dental maturation can possibly be used to make a differential diagnosis of skeletal class III malocclusion. This study aimed to compare dental maturation of first molars in children with skeletal or non-skeletal class III malocclusion in the primary dentition and to determine if dental maturation could be used to make a differential diagnosis of class III malocclusion. Among the children visiting the department of pediatric dentistry in Pusan National University Dental Hospital for anterior crossbite in the primary dentition, 18 were categorized into the non-skeletal class III malocclusion and 34 into the skeletal class III malocclusion. Panoramic radiographs were used to make comparative analysis of dental age and the eruption rate of the first molars. The following results were obtained. No difference was found between chronologic and dental age by the skeletal features or gender, with the latter being older than the former (p < 0.05). The discrepancies in eruption rate of first molars were significantly different between skeletal (18.91%) and non-skeletal groups (16.53%) (p < 0.05). This result implies that maturation of the first molars might be used to make a differential diagnosis of class III malocclusion.

The purpose of this study was to evaluate the effects of Photochemotherapy using a combination of erythrosine and standard halogen dental curing lights on the viability of Streptococcus mutans in the biofilm phase. To investigate the optimum treatment parameters, the researchers controlled the concentration of erythrosine, light irradiation time and the treatment time of erythrosine. The higher concentration of erythrosine (0, 10, 20, 40, 80 M) in the presence of light irradiation created greater effects in reducing the viability of S. mutans. The results showed a statistically significant difference among the antimicrobial effects in 20, 40, 80 M erythrosine. The higher irradiation time of light (0, 5, 15, 30, 60, 75s) in the presence of erythrosine showed greater effects in reducing the viability of S. mutans. There was statistically significant difference in 30, 60, 75 seconds. The higher treatment time of erythrosine (0, 1, 2.5, 5min) in the presence of erythrosine created greater effects on reduction of S. mutans viability. Statistically significant differences were found between 2.5 and 5 minutes of erythrosine treatment time. The results of this study showed that the photochemotherapy on S. mutans using erythrosine and the halogen dental curing lights conventionally used in dental clinics is effective in the condition of 20-40 M erythrosine concentration, irradiation time over 30 seconds, and erythrosine treatment time over 2.5 minutes.

General anesthesia (GA) for dental care in handicapped patients is necessary to facilitate the provision of safe, efficient, and effective quality treatment. The aims of this study were to determine the anesthetic characteristics of handicapped patients in need of dental treatment in these day care units, and to establish for plan to provide better services. 325 patients who had outpatient general anesthesia from January 2005 to March 2014 were assessed for this study. Patients' distribution and treatment patterns were examined. The proportion of male patients (202, 62.2%) was higher than female patients (123, 37.8%) and the largest group of patients were 5 to 10 years old (85, 26.2%). The reasons for general anesthesia included mental and physical disabilities (207, 63.7%), behavior management (84, 25.8%), parent needs (14, 4.3%), and so on. Restorative treatment was the most common procedure with the average of 4.2 teeth treated per one patient and 43 (13.2%) patients underwent general anesthesia for dental treatment more than once. To expand and improve access to the dental care of the disabled, improvement of the health care system, enhancement of their training for dental care by professionals, and enlarging caregivers'understanding of the importance of oral care in the early stages are required.

This study was aimed to retrospectively evaluate the clinical findings and treatments of odontomas in the Korean demographic group. The subject of the present study included 75 odontomas in 74 patients who received treatment from Chonbuk National University Dental Hospital between April 2005 and March 2014. The average age of the subjects were 10.3 years old (range 3 - 23 years old). 42 (56.8%) males and 32 (43.2%) females were in the present study. It was found that compound odontomas were about 4 times more common than complex odontomas. Odontomas equally occurred in both maxillary and mandible. The impaction of permanent teeth (73.3%) was the most common complication of odontomas on adjacent teeth. Most odontomas (96.0%) were surgically removed either to induce spontaneous eruption or to guide orthodontically to occlusion. When the impacted tooth could not be naturally or forcefully erupted to occlusion, it was extracted. Early detection and treatment of odontomas would increase the possible preservation of the impacted tooth by eliminating the source of disturbance. Therefore, this study recommends that periodic radiographic examination from birth until the eruption of the permanent third molar to prevent possible hindrance to the teeth eruption.

The developmental mechanism of root formation is a complex process. Hereditary and environmental factors may affect the morphology of the developing root. A total of 12 cases was presented with permanent first molars with abberant root morphology. Clinically, these teeth appeared as a normal crown. However, radiographically, the root was slender, twisted and characterized by irregular lengths. In addition, root trunk length was shorter and pulp chamber was obliterated. In these cases, periapical radiolucency and loss of lamina dura were often observed. In 6 cases, an abnormal root of the primary second molars were also present, as well as root malformation of permanent first molars. In 3 cases, permanent central incisors also had a dysmorphic crown. These cases almost all had medical history, such as premature birth, brain infection or congenital heart disease in infants. The present paper describes cases of permanent first molars with an abnormal root that are rarely reported in literature. This case may intensify the variation in the permanent first molar and is intended to reinforce the clinician's awareness of rare morphology of the roots.

Incontinentia pigmenti, also called Bloch-Sulzberger syndrome, is a rare X-linked inherited dominant disorder that affects females, but causes spontaneous abortion of prenatal males. Incontinentia pigmenti is a systemic disease with clinical features similar to ectodermal dysplasia, including congenitally missing teeth. The pathogenesis is related to gene mutations in NF-kappa-B essential modulator on chromosome Xq28. Incontinentia pigmenti is caused by a defect in the developmental stage of organs originating from the ectoderm or mesoderm and involves the skin, eyes, hair, teeth and central nervous system. This report discusses the management of three cases of 3 to 5 years old females with incontinentia pigmenti and accompanying multiple missing teeth. The cases had sparse hair, and showed oligodontia and anomalous crowns with supplementary cusps in the posterior teeth and conical anterior teeth. Removable space maintainers were applied, achieving improved esthetics, recovery of mastication and increased self-esteem in the patients.
Regenerative Endodontic Treatment of Infected Immature Permanent Teeth with Dens Invaginatus : A Report of Two Cases

Endodontic management of an immature permanent tooth with dens invaginatus poses a challenge to efficient treatment planning for the clinicians. Because it is difficult to shape, disinfect, and seal the canal space effectively, teeth with complex root canal structures often require particularly extensive and thorough treatment approaches. The purpose of this case report was to share clinical insight from the results of short-term follow-ups after regenerative endodontic treatment with a dens invaginatus. Two immature maxillary lateral incisors with Oehlers type I and III dens invaginatus and infected necrotic pulp were treated using regenerative endodontic procedures. For the type III dens invaginatus case, an unusual approach toward redesigning the complex internal structure was taken, in order to have sufficient infection control and sealing. Cone-beam computed tomography (CBCT) and a surgical operating microscope were used to aid visualization and treatment. As a result, regenerative endodontic treatment appears to be effective for managing immature permanent teeth with complex dens invaginatus, and can lead not only to clinical and radiographic resolution, but also increased thickness of the dentinal walls.

Numerous challenges in treating permanent dentition are encountered, especially in treating immature teeth with pulp necrosis. Historically, calcium hydroxide application during long periods of time was used to induce the formation of a calcific barrier across the open apex. In 2004, a new treatment modality for the management of the open apex was introduced. This treatment was named as 'revascularization' and gained acceptance among dentists. The protocol was different from the traditional apexification techniques in that the canal was irrigated and disinfected with a combination of three antibiotics (ciprofloxacin, metronidazole and minocycline). At the next appointment, bleeding was induced and the canal was sealed with MTA. Successful regenerative endodontic treatment of necrotic immature permanent teeth can provide continued root development, increased thickness in the dentinal walls and apical closure. These developments of a functional pulp-dentin complex have a promising impact on retaining the natural teeth, the goal of the dental health care.
