A STUDY OF ATTITUDES TOWARD AND USE OF PIT AND FISSURE SEALANTS BY DENTISTS IN CHON-BUK AREA
Kim, Jae-Gon ; Baik, Byeong-Ju ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 429~438
Since the introduction of pit and fissure sealants in the early 1970's, many studies have been published amply documenting the efficacy of these materials as caries-preventive agents. However, the acceptance of the technique by dentist has been questionable. This survey was investigated the attitudes toward and use of pit and fissure sealants by dentist in Chonbuk area. The results were as follows: 1. Utilization of pit and fissure sealants is very high. Only 15% of dentists never use pit and fissure sealants, whereas 85% generally use pit and fissure sealants. 2. Most dentists reported that their knowledge of pit and fissure sealants was gained through dental schools education. 3. Concern about difficult to sell' to patient, poor retention of pit and fissure sealants and unsubstantiated by research were given as the main reasons why pit and fissure sealants was not used. 4. Patient demands and various educate program were given as important factors that would lead to increase use of pit and fissure sealants.

The purpose of this study was to investigate the distribution of nerves in the periodontal ligament of a dog's primary teeth by each developing stage. The distribution of nerves in the periodontal ligament were investigated by means of immunohistochemistry for detection of neurofilament protein (NFP). The results were as follows: The NFP-immunoreactive nerve fibers were found to be densely distributed in the apical third of the periodontal ligament, while they were sparse in the coronal two third, in both primary and permanent teeth. In generally the density of distribution and degree of arborization of nerve fibers in periodontal ligament of primary teeth revealed a poor appearance compared with that of permanent teeth. Periodontal ligament in anterior teeth showed more abundant nerve innervation than posterior teeth, and the periodontal ligament of the bifurcation area in posterior teeth roots were not observed to have nerve fiber. The density of nerve distribution in the periodontal ligament of primary teeth was reduced according to the physiological root resorption and nerve fibers were not observed in the surrounding area on the root of the exfoliation stage in primary teeth. The distribution of nerve fibers in mucogingival tissue, was poor innervated according to the aging of the dogs. A more abundant distribution of nerve fiber was represented in the lingual mucogingival tissue than in the labial side. Most of the nerve endings in the periodontal ligament of primary teeth showed a tree-like appearance. However, the typical Ruffini-like nerve endings were not observed.

The purpose of this study was to investigate the relationship between the caries experience and anxiety level to the dentist in the preschool children. 511 preschool children were brought to the dental hospital and examined for caries experience. Caries experience was measured as dDT index, fFT index, dDfFT index, dDT rate, and fFT rate. Children were requested to draw a dentist. Drawings were analyzed by the method of Human Figure Drawing Anxiety Score. Pearson correlation coefficents and their significance were calculated between caries experience and anxiety scores. There were significant negative correlation between fFT index and anxiety scores, between dDfFT index and anxiety scores, and between fFT rate and anxiety scores. There was significant positive correlation between dDT rate and anxiety scores. The results seemed to suggest that dental treatment experience reduced children's anxiety toward dentists. But, because there was obvious negative correlation between age and anxiety scores, age factor should be considered in the interpretation of the results.

The purpose of this study was evaluation of the oral health of cerebral palsied children by considering the DMFT index. The 31 cerebral palsied children(Male 20, Female 11) participated in the study, and mean age was 11.3 years. All patient were examined for determination of decayed tooth, missing tooth, filled tooth. For children with only deciduous dentition, the dmf system was used; for children with only permanent dentition, the DMF system was used; for children with mixed dentition, a combination of two systems(dmf and DMF) was used. The results were as follows: 1. In the deciduous dentition, dmft index was 11.60.(dt rate ; 83.62%, mt rate ; 12.07%, ft rate ; 4.31 %) 2. In the mixed dentition, DMFT index was 12.25 and dmft index was 10.75.(DT rate ; 90.00 %, MT rate ; 0 %, FT rate ; 10.00 %, dt rate ; 60.53 %, mt rate ; 28.95 %, ft rate ; 10.52 % ) 3. In the permanent dentition, DMFT index was 8.16.(DT rate ; 87.77 %, MT rate ; 11.51 %, FT rate ; 0.72 %)
DIFFICULTY IN MANAGING THE BEHAVIOR AND TIME REQUIRED FOR TREATING THE PEDODONTIC PATIENTS IN ASSOCIATION WITH THEIR AGE
Kim, Kwang-Chul ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 469~485
The present study was undertaken to examine the relationship between time required for each step in the treatment process for pedodontic patients. and age of the patients, and experience of special training for pedodontics and career of dental practitioners. Information of these matters was gained from 580 questionnaires collected from 69 practitioners (62 male and 7 female). The questionnaires included questions about the patients' sex(303 male and 207 female) and age. The patients were categorized into 5 different age groups : Group 1, age
-year ; Group 2,
-year ; Group 3,
-year ; Group 4,
-year ; Group 5,
-year. The questions about the dental practitioners were the years of experience in private dental practice(5 years or more than 5 years) and whether or not they took the special training for pedodontics in the authorized institutes. The practitioners were asked to answer the questions about Frankl scale of the patients' behavior during the treatment, and time spent for managing the patients to be subjected to local anesthetic injection (the first behavior control), time for the injection, and time for the subsequent treatment. The results obtained by analyzing the information collected from the questionnaires were as follows : 1. The younger the patients, the lower the Frankl scale was counted at the time of the first behavior control, injection, and the subsequent treatment(p<0.001). 2. The lowest Frankl scale was scored during the injection regardless of the age of the patients. 3. Time for management and treatment was decreased in the order of age Groups 1 and 2< Group 3 < Groups 4 and 5. 4. The patients showed a more positive frankl scale in response to the treatment performed by those who were more-experienced in dental practice as compared with those were less-experienced. 5. Pedodontic training experience of the practitioners did not appear to influence the patients with respect to the treatment time and Frankl scale.
DISTALIZATION OF THE MESIAL DRIFTED UPPER FIRST MOLAR WITH OPEN COIL JIG IN THE MIXED DENTITION: A CASE REPORT
Kim, Beung-Chang ; Kim, Jin-Tae ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 486~490
Maxillary first molar is the key in normal occlusion. Mesial drifting of maxillary first molar result form early loss of second deciduous molar. Mesial drifted maxillary first molar was treated by headgear, Hawley appliance with screw, brasswire, etc. But, these appliance should be necessary for patients cooperation. Recently, several appliance for molar distalizing without patients cooperation has been introduced. We are reporting in this paper about distalizing of mesial drifted maxillary first molar because of early loss of deciduous second molar by open coil jig. Distalization of molar by open coil jig is predictable, rapid, painless method without mecesscity of patient cooperation.

Kim, Jung-Wook ; Shon, Dong-Su ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 491~495
The ectopic eruption is defined rise to be abnormal eruption, which gives to displacement of the teeth and abnormal root resorption of adjacent teeth. The ectopic eruption of first permanent molar is approximately 2-4% of the population, most of them are in the maxilla, rarely in the mandible. In the case of the second permanent molars, most of them are found in the mandible for the reason of the arch length discrepancies and large size of the teeth. The ectopic erupted molars should be treated early in order to coordinate normal growth pattern and to obtain good occlusal support. So, this should be early diagnosed and treated. But, ectopically erupting molars are often self-corrected, hence periodic follow-up is required. The methods of the treatment are largely classified into surgical, surgical-orthodontic, and orthodontic method. Especially in orthodontic method, they are divided as follows; appliances that is positioned at the contact point for unlocking and the distal movement, fixed and removable appliance that is connected to more than one tooth, and occlusion guiding method after disking or extraction of the second deciduous molar. The report presents the good results in treating patients, whose chief complaint was ectopic eruption of mandibular permanent molars.
TREATMENT OF INJURED PERMANENT TEETH FROM TRAUMA : A CASE REPORT
Kim, Jun-Hye ; Hahn, Se-Hyun ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 496~503
Three cases of treated permanenet teeth are presented. A horizontal root fracture was treated by endodontic treatment in which coronal segment only was done. A replanted incisor is ankylosed because of false restorative method and long extraoral period. Resorption of traumatized bone can be seen in the third case. The prognosis of traumatized incisor depends on proper restoration, adequate amergency treatment and periodic follow-up check.
DENTAL FEATURES OF ACHONDROPLASTIC CHILD : A CASE REPORT
Jeon, Hyun-Cheol ; Kim, Chong-Chul ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 504~509
Achondroplasia is characterized by undergrowth of long bones and cartilages and by low height. The name of this disease had been called classical chondrodystrophy, dyschondroplasia, chondrodystrophy and micromelia before Parrot reported the term of this disease as Achondroplasia. We are reporting in this paper on an 3-year and 4-month-old boy with achondroplasia. The dental findings are as follows: 1. Open bite and relatively mandibular prognathism were observed in the front teeth. 2. The size, number, shape, structure of the teeth were usual and the tongue was a little bigger than the normal. 3. The metacarpal bones were short and broadening. Mesial, distal border of the prox. phalanges were irregular and also trabecular pattern was abnormal in the hand-wrist P-A view. 4. According to lat. cephalometric analysis, the cranial basis was underdeveloped.
ORTHODONTIC AND/OR PHYSIOLOGIC POSITIONING OF IMPACTED MAXILLARY CENTRAL INCISORS
Lim, Eun-Kyung ; Choi, Yeoung-Chul ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 510~517
It is a relatively common clinical experience to see a impacted maxillary central incisor. This is apparent at the dental age of about eight years and over, when the patient is in the early mixed dentition stage. The adjacent teeth may tilt toward the site of the missing tooth with resulting space closure and midline deviation. Most often, the central incisor is impacted labially. The labial impaction has been indicated as the most difficult to manage. Each of the current articles describing labial impactions shows at least one case with mucogingival recession or a minimal zone of attached gingiva. This report described the surgical uncovering and orthodontic-physiologic positioning methods with labially impacted maxillary central incisors. Through surgical exposure and direct bonding of lingual botton, the central incisors were brought into proper eruption path with elastic traction. The case 1 and 2 were treated with the physiologic erupting forces. The case 3 was applied with continuous orthodontic force. The case 1 and 2 resulted in good positioning, good esthetics and adequate width of keratinised gingiva. The case 3 resulted in local inflammation and inadequate width of keratinised gingiva.
THE MANAGEMENT OF TRAUMATICALLY INTRUDED TEETH : A CASE REPORT
Han, Young-Hee ; Kim, Kwang-Chul ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 518~524
A traumatically intruded tooth is one that is forcefully and abruptly dispaced from its position into the surrounding alveolar bone. Although intrusion of permanent teeth is infrequent, the sequelae compromise the longevity of the tooth and often include pulp necrosis, internal and external root resorption, rupture of periodontal ligament and loss of marginal bone. The purpose of this study was to examine three common management techniques for traumatic intrusion, observation for re-eruption, surgical repositioning & fixation and orthodontic extrusion. In the recent, the accepted treatment was to allow the permanent teeth to reerupt spontaneously for 6-8 weeks. If this did not occur, orthodontic traction was applied. The pulpal status of the teeth was monitored and either calcium hydroxide therapy or conventional endodontics was instituted following pulpal necrosis depending on the maturity of the root end. Pulpectomy and a calcium hydroxide filling were also the treatment of choice if there was evidence of internal or external root resorption. This will reduce the chance of root resorption and provide a period of monitoring prior to a definitive root canal filling.

Lee, Eun-Young ; Lee, Chang-Seop ; Lee, Sang-Ho ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 525~532
The purpose of this report was to evaluate the effect of Dental Electronic Anesthesia on pain inhibition for clinical use. The subject for this study were 30 children whose Frankl behavioral rate is positive. The subjects was divided into two groups, the first group described by control group and the second group described by experimental group anesthetized with Dental Electronic Anesthetic device. And then three kind of treatments were done : extraction of deciduous teeth, application of rubber dam, cavity preparation for preventive resin restoration. 3M Dental Electronic Anesthesia System was used for this study : its electric impulse stimulate the skin surface by external electrode pads. The results were as follows. 1. Degree of the pain & the apprehension decreased in experimental group. 2. Degree of the pain & the apprehension showed statistical differences among three treatments procedures in the control group but, not showed statistical differences in the experimental group.
TREATMENT OF HEAVY BUCCAL FRENUM USING FRENOTOMY AND AUTOGENOUS FREE GINGIVAL GRAFT IN CHILDREN : A CASE REPORT

The mandibular buccal frenum is a fold of mucous membrane at the posterior labial vestibule, that attaches the lips and the cheeks to the alveolar mucosa, gingiva, and underlying periosteum. The buccal frenum becomes a problem if its attachment is too close to the marginal gingiva. It may then pull on healthy gingiva, encourge plaque formation and interfere with tooth brushing. Heavy buccal frenum mucogingivally results in insufficient attached gingiva, inadequate vestibular depth and high frenum attachment and also difficulty in eruption of mandibular second premolar. Frenectomy in various forms has been used for many years to remove the influence of the frenum. Unfortunately, the results are not always ideal and there is often postoperative relapse because of muscle pull. In this treatment, frenotomy was used in conjuction with autogenous free gingival graft with the object of removing the influence of the buccal frenum and creating an adequate and stable width of attached gingiva. We observed decrease in muscle pull, adequate width of attached gingiva and increased vestibular depth in addition to progressive eruption of second premolar. Periodic follow-up is needed for evaluation of relapse, grafting gingiva and also space regaining for second premolar.

The authors treated three patients who chiefly complained functional anterior crossbite due to premature loss of primary molars by using removable space maintainer and functional appliances. In orthodontic practice, the mandibular rest position and the possibility of taking construction bite have been as the criteria for evaluation of functional factors involved in anterior crossbite. Functional anterior crossbites, if left untreated, may have deleterious effects on the development and function of craniofacial complex and TMJ. Objectives of the treatment were as follows: 1) to recover vertical dimension 2) to eliminate functional disharmony 3) to correct anterior reversed occlusion 4) to attain good facial esthetics 5) to prevent unfavorable growth of jaw & dentition Characterized craniofacial morphology resulting from the premature loss of deciduous molars could be recovered following the correction of crossbite. Therefore, it is recommended that in orthodontic diagnosis of functional anterior crossbite due to premature loss of deciduous molars, the craniofacial abnormality affected by that should be considered.
TREATMENT OF FUNCTIONAL POSTERIOR CROSSBITES IN THE PRIMARY AND EARLY MIXED DENTITIONS : CASE REPORT
Lee, In-Jeong ; Kim, Hyun-Jung ; Nam, Soon-Hyeun ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 547~554
Posterior crossbites are abnormal buccal, or lingual relationship of a tooth or teeth of the maxilla, the mandible, or both when the teeth of the two arches are in occlusion and involve the molars and premolars. Posterior crossbites are classified as dental, muscular(functional), or skeletal. In an effort to avoid occlusal interferences caused by the inadequate arch width, the patient deviates the mandible laterally upon closure to achieve maximum intercuspation. This is described as functional posterior crossbite. Correction of functional posterior crossbites in the primary & early mixed dentition as early as possible after diagnosis has been recommended, because crossbites do not automatically improve with the eruption of the permanent teeth. Functional posterior crossbites, if left untreated, may have deleterious effects on the development and function of the TMJ. The diagnosis and management of three cases is presented. Each patient with functional posterior crossbites is treated using the bilateral maxillary expansion appliance.

Among the permanent teeth. the first permanent molars play the greatest role in occlusion and function. So, the congenital missing, abnormal reuption or abnormal formation of the first permanent molars in the course of arch development would inflict normal development of dental arches. Therefore, early detection of abnormal cases related to first permanent molars and understanding of current and predictable clinical problems are essential for proper occlusal guidance in children. With the aim of investigating the clinical patterns of delayed eruption of first permanent molars in children, panoramic tomograms of the childern in mixed and early permanent dentition were observed and analyzed. The results were as follows: 1. Among the delayed eruption of first permanent molars, on tooth or bilateral teeths were affected most frequently. Delayed eruption was more prevalent in maxilla than in mandible. 2. The formation of tardily erupted teeth were also delayed. 3. Delayed eruption was generally limited in first molars or molar segments. 4. Delayed eruption of first permanent molars is accompanied by abnormal position of tooth germs, for example, ectopic eruption, delayed dental age, delayed localized tooth formation and generalized congenital missing. 5. There was a tendency of delayed formation or congenital missing of second molars distal to tardily erupted 1st molars. And that was more marked in maxilla than in mandible. 6. There was reported that affected 1st molars show various size and shapes. Maxillary 1st molars showing delayed eruption showed a tendency of having 3 cusps. But, tardily erupted mandibular 1st molars showed no significant reduction in mesiodistal dimension, as reported. 7. In some cases, the delayed eruption of 1st permanent molars was associated with ectopic eruption, but their formation was not usually retarded. 8. In skeletal class III cases, there showed a tendency of mandibular 1st molars to erupt earlier than maxillary 1st molars with greater interval than in normal occlusion.

The autotransplantation procedure were performed for the cases with impacted maxillary anterior teeth, which were thought unrealistic by the treatment with surgical exposure and orthodontic traction into the arches. The results were as follow : 1. As the treatment with autotransplantation is the last resort, the case indicated should be selected cautiously by adequate case analysis. 2. In order to reduce postoperative complication, damages to periodontal ligaments and adjacent bony structures should be minimized by conservative surgical procedures. 3. After autotransplantation procedures, postoperative endodonic treatment and continuous follow-up check with clinical and radiographic examination should be followed. Although the autotransplantation procedure is not the treatment of choice in most cases, it was thought to be a good alternative in certain cases when orthodontic treatment is unrealistic with continuous study to overcome the handicaps.
PROSTHODONTIC AND ESTHETIC RESTORATION OF ECTODERMAL DYSPLASIA WITH ANODONTIA : A CASE REPORT
Lee, Min-Ha ; Yang, Kyu-Ho ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 570~576
Ectodermal dysplasia is characterized by a partial or complete lack of primary and permanent teeth, other ectodermal structures that may be affected include the skin, hair, and sweat glands. The patient with the so-called anhidrotic type of ectodermal dysplasia exhibits dry skin, lack of sweat glands, sparse eyebrows, body hair, saddle nose, and everted lips. Genetic basis of anhidrotic ectodermal dysplasia is recessive and sex-linked, being manifested chiefly in males, but this is debatable. A 6-year-old boy, with typical signs of anhidrotic ectodermal dysplasia, was presented. Prosthetic restoratoins are of great value to these patients, both from the standpoint of function and for psychologic reasons. The need for complete denture is critical during preschool periods and continues into adulthood. The following case report is an approach to the management of a patient with anhidrotic ectodermal dysplasia.
A CASE REPORT ON TREATMENT OF CLASS II MALOCCLUSION WITH TWIN BLOCKS IN GROWING CHILD
Yang, Kyu-Ho ; Park, Jae-Hong ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 577~585
The Twin Blocks technique was developed by Dr. William Clark of Scotland during the early 1980's. Twin Blocks are an uncomplicated system that incorporates the use of upper and lower bite blocks. These blocks reposition the mandible and redirect occlusal forces to achieve rapid correction of malocclusions. They are also comfortable and the patients wear them full-time-inducing eating time. Occlusal forces transmitted through the dentition provide a constant proprioceptive stimulus to influence the rate of growth and the trabecular structure of the supporting bone. The features of Twin Blocks mean easier and quicker treatment. The occlusal inclined plane is the fundamental functional mechanism of the natural dentition. Twin blocks are bite blocks that effectively modify the occlusal inclined plane to induce favorably directed occlusal forces by causing a functional mandibular displacement. Upper and lower bite blocks interlock at a
angle and are designed for full-time wear to take advantage of all functional forces applied to the dentition including the forces of mastication. The patients who were treated with modified Twin Blocks, and following results were observed: 1. Large overjet and deep overbite were corrected. 2. Class II molar relationship was changed into Class I. 3. Labial inclination of upper incisors was corrected by adjustment of labial bow of upper bite block. 4. The profiles of two patients were improved by anterior displacement of mandible.

Hur, Sun ; Kim, Jae-Gon ; Baik, Byeong-Ju ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 587~592
The dentigerous cyst originates through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium or between this epithelium and the tooth crown. It is always associated with unerupted teeth. There are two methods of treament which are generally accepted. One is the enucleation of the cystic sac in its entirety, the other is the Partch operation, or the marsupialization, by which the cyst is uncovered or "deroofed" and the cystic lining made continuous with the oral avity or surrounding structures. The present case report showed that in instance of dentigerous cyst & odontogenic keratocyst surgical enucleation followed by careful excision of all cyst wall was successfully carried out and recovery and healing were rapid and uncomplicated.
ESTHETIC IMPROVEMENT OF DISCOLORED TEETH : A CASE REPORT
Jung, Ho-Suck ; Kim, Dae-Eop ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 593~598
There were two cases of esthetic improvement of discolored teeth. First case was 12-year-old girl whose upper right central incisor was discolored after traumatic injury. She was treated by walking bleaching technique. Endodontic retreatment was done, and then the mixture of Superoxol and sodium perborate was applied and changed every week. After 3 weeks, esthetic result was obtained and fracture site was rcovered with light-curing composite resin. Second cases was 11-year-old girl whose teeth were discolored by fluorosis. She was treated by vital bleaching technique. A resin splint was made and then 30% and 15% carbamide peroxide was applied using this splint. After 4 weeks, a noticeable improvement in the color and the brightness of the teeth was achieved.

THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 599~604
Very few reports are available on the occurrence of abnormality of both enamel and dentin. This case has some characteristiced of both amelogenesis imperfecta and dentinogenesis imperfecta. Clinically, the enamel of primary dentition was completely absent and when the permanent teeth came to the pediatric dept. of Dankook University Dental Hopital for treatment. Fixed-removable type resin plate was delivered to increase vertical dimension and to solve esthetic and functional defects. Hypoplastic teeth were restored either stainless steel crown or composite resin restoration or both. The periodic recall check and oral hygiene education are recommended.

Leem, Cheol-Soo ; Kim, Yong-Kee ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 605~610
Resricted opening of the mouth in children can be derived from a variety af extra and intra articular causes. A 5-year-old female patient with an elongated right coronoid process and with congenital missing teeth came to clinic for wearing of esthetic denture. A proper medical consultation and laboratory test had done for assessment a systemic syndrome related to her dental anomalies. The result was that her systemic findings dindn't accord specific signs and symptoms of Hallermann-Streiff syndrome. Unilateral coronoidectomy was fulfilled to improve mouth opening and subsequently endodontic and restorative procedure. Maxillary partial denture was delivered for esthetic problem. The periodic recall medical/dental check-up are recommended.
TREATMENT OF MISSING CENTRAL INCISORS USING SPACE REGAINING AND MARYLAND BRIDGE : CASE REPORT
Jun, Sang-Eun ; Kim, Yong-Kee ;
THE JOURNAL OF THE KOREAN ACADEMY OF PEDTATRIC DENTISTRY, volume 21, issue 2, 1994, Pages 611~616
A major cause of missing permanent incisors is congenital abscence and extraction because of trauma and pathologic condition. The request for restoration of missing or spaced anterior teeth is common in dental practice. Problems, such as the tilting, drifting, and rotation of teeth adjacent to the space, complicate the restoration of apperance, and a normally simple restorative dental procedure may become difficult. There are two primary treatment alternatives to improving a dentition's irregular and spaced apperance-closing the space by orthodontic means or providing a prosthesis to disguise the space. The treatment choice depends on many variables, but, as a general rule, patients with a normal overbite, overjet, and buccal relationship are better treated by maintaining the sapce and providing a prosthesis, either fixed or removable. This case report presents two cases : Traumatic loss of maxillary right and left central incisors, Extraction of malformed mandibular right central inciosr. The loss of central incisor space was regained by the fixed-removable and fixed orthodontic appliance, and then Maryland bridge was cemented.
