The objective of this study was to determine the effectiveness of topical 5% EMLA cream versus 20% Benzocaine gel in reducing pain from intra oral needle insertion alone as well as injection of anesthetic. The 2 topical anesthetics were tested against each other bilaterally using a randomized, controlled, single blinded, split mouth design. Phase I was conducted to find out the rapidity of onset action of the two agents on anterior/posterior vestibules and anterior/posterior palatal mucosa. Phase II was conducted to evaluate the efficacy of the two topical anaesthetic agents in reducing the pain of intraoral injections. The agents were left in anterior/posterior vestibules and anterior/posterior palatal mucosa for the amount of time recorded in phase I. Subjects recorded pain on a 100-mm modified visual analog scale(VAS). A pulse oximeter was used to recorded the preoperative and postoperative pulse rates. In phase I of the study, two topical agents showed the longer onset of action at anterior part and vestibules than posterior part and palatal mucosa. EMLA cream showed the rapidest onset of action compared to benzocaine gel except on anterior palatal mucosa. In phase II of the study, the VAS grading of the pain for anesthetic administration showed EMLA cream was significantly(P<.05) better in elimination or reducing the pain on the anterior/posterior palatal mucosa. In conclusion, EMLA cream showed the rapidest onset of action compared to benzocaine gel except on anterior palatal mucosa. EMLA cream was found to be superior to Benzocaine gel with regards to pain reduction for anesthetic administration especially on anterior and posterior palatal mucosa.

Recently, the number of multi-cultural families have been on the rise for years in Korea. Although social concerns are on the increase, there is still no basic data of their oral health state. In this study, we examined the caries prevalence of mother-child pairs from some korean families and multi-cultural families, and collected some saliva from them. We evaluated Streptococcus mutans level and investigated the serotype distribution of Streptococcus mutans of them to confirm the transmission in mother-child pairs. As a results, to the Korean families, the percentages of serotype c, e, f, k were 95%, 10%, 10%, and 10%. And to the multi-cultural families, the percentages of serotype c, e, f, k were 68.8%, 31.25%, 43,75%, 18.8%. But, there is no significant relationship between the number of serotype per person, caries prevalence, and Streptococcus mutans level(p>0.05). In conclusion, there are differences of serotype distribution of Streptococcus mutans between the two families. Nevertheless, matching rate of more than one serotype between mother and their child was high (92.86%). So, vertical transmission of Streptococcus mutans in mother-child pairs could be demonstrated.

The aim of this study was to assess the outcome of MTA apexification in young permanent anterior teeth. Among the patients with the traumatized permanent incisors which were treated with MTA apexification, the dental records and radiographs were examined only for the patient who had follow-up examination at least 3 months after the treatment. Forty nine patients with 64 teeth were included in this study. Demographic information, location and type of teeth and periodontal injury, pre-treatment periapical lesion, clinical symptoms, status of MTA filling, healing of apical lesion and apical barrier formation after treatment were investigated. The outcome based on clinical and radiographic criteria were assessed. The results were as follows 1. Of 64 immature permanent incisors with MTA apexification, the clinical and radiographic success rates were 89.1% and 73.4%, respectively. 2. The maxillary incisors showed significantly higher success rates than the mandibular incisors. 3. There was no statistically significant difference in success rates among the teeth with different types of teeth and periodontal injury. 4. The status of MTA filling did not influence the clinical and radiographic success.

The number of patients requesting services of pediatric dental clinics has been steadily increasing in South Korea. The pediatric dental clinics are comprised of hospital-based clinics and local clinics. The purpose of this study was to analyze new-patient distribution and to survey the motives for visiting the department of pediatric dentistry at Seoul National University Dental Hospital(SNUDH), utilizing questionnaires for parents from May to July 2010. The results are as follows: 1. Age distribution showed that 0-3 year-olds formed the largest group of 29.3%. The average age of patients was 6.2 years old. 2. In the surveys for the parents, the major reason for visiting SNUDH was the referral from other clinics(30.6%). 3. The 75% of patients previously visited other clinics before visiting SNUDH. 1) The greater number of patients(52%) visited general practitioner's clinic than pediatric specialists(48%). 2) More than 90% of the patients visited SNUDH after visiting other clinics for reassuring diagnosis and referrals. 3) The crucial deterring factor of being treated at SNUDH was difficult accessibility.

The objective of this study was to compare the shear bond strengths of five dentin adhesive systems cured with three different light curing sources. Seventy five noncarious permanent teeth were collected and stored in an 0.1% thymol solution at room temperature after extraction. The tested adhesives were: Adper Scotchbond Multi-purpose Plus Adhesive (SM) Adper Single bond 2 (SB), Clearfil SE Bond (SE), Adper Prompt L-Pop (PL), G-Bond (GB). And three light curing unit systems were used: Elipar Free light 2(LED), OptiLux 501 (Halogen), Flipo (PAC). For the shear bonding test, the labial and lingual surfaces of permanent teeth were used. To obtain a flat dentin surface, the labial and lingual surfaces of the teeth were sanded on SiO2 with number 600 grit and then divided into 15 groups of 10 surfaces each. All samples were theromocycled in water
for 1000 cycles. The results were as follows: 1. When cured with Freelight 2, the shear bond strength of SM was significantly higher than that of PL, GB (p<0.05), whereas no significant difference was found among those of any other bonding agents. 2. When cured with Optilux 501, the shear bond strength of SM was significantly higher than those of any other bonding agents (p<0.05), whereas no singnificant difference was found among those of andy other bonding agents. 3. When cured with Flipo, the shear bond strength of SM was significantly higher than those of SB, SE, GB (p<0.05), whereas no significant differences was found among those of any other bonding agents. 4. For comparison according to three different light cure unit system, except SB and GB, each three dentin bonding agents showed no significant difference. For SB, only Freelight 2 was significantly higher than the others, with no significant difference between Optilux 501 and Flip. For GB, Statistically significant difference was found only between Freelight and Flipo.

An immature tooth with infected pulp has numerous potential complications. Conventional apexification with calcium hydroxide has several disadvantages, including susceptibility to tooth fracture. This method does not promote continual root development. Pulp revascularization of a necrotic, immature permanent tooth will allow further development of the root and dentinal structure. Disinfection of the root canal system is a prerequisite for pulp revascularization and tissue regeneration. A combination of antibiotic drugs (ciprofloxacin, metronidazole, and minocycline) is effective for disinfection of necrotic pulp, and has been used successfully in regenerative endodontic treatment. These case reports involve the treatment of 3 immature permanent teeth with necrotic pulp using a 3-Mix paste and mineral trioxide aggregate. All cases showed the notable apical maturation with closure of the apex and increased thickness of dentinal walls. This approach suggests a paradigm shift in treating endodontically involved immature permanent teeth from the traditional apexification with calcium hydroxide to the conservative approach by providing a favorable environment for tissue regeneration.

Supernumerary teeth are dental abnormalies in the permanent dentition and the primary dentition. The etiology is unclear, but it may occur due to dichotomy of the tooth bud or hyperactivity of dental lamina. They occur more in the permanent dentition than in the primary dentition, with the most common site being the premaxillary area. Supernumerary teeth can be classified by morphology and position. Supplemental tooth refers to normal shape tooth. The treatment of supernumerary teeth depends on its shape, position, effect on dentition, and child's physiological condition. In this case, supernumerary primary tooth in the maxillary molar area was revealed by radiographical and clinical examination, but it was difficult to determine which is the supernumerary tooth. The tooth on the mesial side was extracted to induce the formation of adequate space and to prevent excessive space loss, and the result was favorable.

Cornelia de Lange syndrome(CdLS) is a well-described multiple malformation syndrome typically involving proportionate small stature, developmental delay, specific facial features, major malformations, and behavioral abnormalities. Dental issues include micrognathia, crowding of teeth, small teeth, absent teeth, poor oral hygiene, and periodontal disease. We present a case of CdLS in a 10-year-old girl. Micrognathia, crowding of teeth, and bifid uvula are the characteristic features of this case. Dental treatments for this child including preventive and restorative procedures were performed under outpatient general anesthesia.

Early eruption refers to an accelerated eruption of a tooth beyond the normal eruption period. The clinical findings of an early erupted tooth with little formation of crown and/or root include severe mobility, pain on chewing, hypocalcification of the enamel, and inclination, displacement, and rotation of the tooth. The radiographic findings include underdeveloped root and insufficient bone support. Early eruption of a permanent tooth can cause several complications such as chronic trauma, pain, edema, an increased rate of premolar impaction and tooth displacement and/or rotation. Therefore, when a permanent tooth erupts earlier than its normal eruption period with accompanying symptoms, appropriate treatments should be done as soon as possible. A female patient of age 7 without any systemic disease was referred from a local dental clinic with chief complaint of severe mobilities and pain in both upper first premolars. According to the clinical and radiographic examinations, the permanent teeth erupted earlier with barely formed roots, severe mobilities, edema, and pain. This case is to report the successful accomplishment of root formations and stabilization of teeth after applying intraoral fixed appliances using bands and spurs for 14 months.

Rett syndrome is a X-linked genetic neurological disorder characterized by developmental regression, particularly in relation to expressive language and use of the hands, together with profound mental retardation, that almost exclusively affects females. Oral manifestations of the disease are commonly associated with the clinical conditions such as convulsion activity, difficulties for oral hygiene behavior, walking problems and oral/digitalmanual habits. Bruxism is the most frequently observed oral habit in patients with Rett syndrome. Two cases with the Rett syndrome were reported. Both patients had the typical manifestations like stereotypic hand movement, bruxism and digit-hand sucking. Caries control for the patients was perfomed under general anesthesia.

Supernumerary teeth are in excess of the normal number of teeth in either the primary or permanent dentitions. They are classified into supplemental teeth resembling those of the normal series and rudimentary teeth with abnormal shapes, according to their form. Most of the supernumerary teeth are rudimentary form, and supplemental teeth are much less common. Sulppemental teeth are most common in the permanent maxillary lateral incisor area and clinicians should be careful with differential diagnosis from normal teeth. Unerupted supernumerary teeth may produce several complications such as delayed eruption, displacement of permanent teeth, diastema, root resorption and cyst formation. Early detection and proper treatment plan according to the tooth alignment and root formation stage are important. Here we report 3 cases of unilateral or bilateral normal incisor shaped supernumerary lateral incisors treated by eruption observation, surgical extraction and orthodontic treatment with resin build-up.

The pulp infection of primary tooth is often caused by dental caries or trauma. But, if it is not managed properly, it can be produce the periapical lesion. The periapical lesion can cause some complications such as enamel hypoplasia, displacement, root dilaceration and impaction. Treatment options of displaced permanent successor are clinical and radiological follow-up after extraction of primary teeth, surgical opening, orthodontic traction, transplantation and extraction. In these cases, the premolars with abnormal eruption path caused by periapical lesion of the primary tooth have shown successful spontaneous eruption just as a result of extraction of infected primary tooth and space maintenance.

Ranula is a mucosal cyst that occurs in the mouth floor. This is a pseudo cyst caused by mucous retention within the tissue due to the rupture of catheter in the salivary gland. Ranula occurs mainly in a unilateral form and is characterized by painless bluish transparent swelling, with a increasing mass size. If the size is large, it can cause discomfort during swallowing, pronounciation, and mastication, but external swelling and infection is rare. Treatments include observation for spontaneous resolution, simple incision and drainage, marsupialization and excision. Marsupialization done by removing parts of the cyst wall and connecting it to the oral mucosa. It is a conservative procedure and recommended for children. It has advantages such as maintaining outline of oral tissue and less risk of damaging anatomic structure. Recurrence is common, mostly occurring within 4 months after surgery. This case is about a eight-year-old girl with ranula on the right mouth floor. This patient was treated with marsupialization that is one of treatment for ranula, and recurrence was not observed.

Fibrodysplasia ossificans progressiva(FOP) is characterized by episodes of permanent heterotopic ossifications of soft tissues throughout the body. FOP is inherited in an autosomal dominant pattern, but most cases result from new mutations in the ACVR1 gene. Even minimal trauma can cause permanent ossifications of soft tissues and give rise to complications following routine dental care. Dental block anesthesia, severe stretching of the jaw and biopsies are all contraindicated in children with FOP. There is no effective treatment. Since the prevalence of FOP is very low and most patients with FOP are misdiagnosed during childhood, they undergo dangerous and unnecessary treatment that can lead to permanent harm. For patients with FOP, early diagnosis and prevention of complications are most important. This study aims at contemplating the characteristic features and consideration factors for the dental treatment of FOP patients in relation to the case of an eight years-and-one month old boy who was referred to Pediatric Dentistry due to prolonged retention of mandibular right and left deciduous central incisors after being diagnosed with sporadic FOP at Pediatric Orthopaedics, Seoul National University Hospital, and received dental treatment without the exacerbation of the FOP symptoms.
