JOURNAL FREE ACCESSUp to about twenty years ago, a practicable method for the treatment of the severe pathological hard tissue resorptions peculiar to primary teeth, such as internal root resorptions (IR) and the alveolar bone resorptions (BR) of periapical and interradicular lesions, had been unknown as an untouchable field, and therefore extraction had been obligatory. In order to solve the problem, established was the novel endodontic therapy, namely FC-CV therapy, which fell into three types treatments: typeI, typeII and typeIII.
The typeI treatment originally established is effective against the IR localized within a root canal and the IR perforating to cause the largely extended BR with abscess formation. The typeIItreatment is a kind of vital pulpotomy to which the typeIis applied. This type is effective against chronic coronal pulpitis and the acute, chronic apical periodontitis accompanied with largely extended BR due to abscesses in spite of root pulps remaining vital. The typeIII treatment is the root canal treatment based on the EBM of the typeIand II treatments and is effective against the acute, chronic apical periodontitis (resulting in necrotic pulps) complicated with largely extended BR caused by an abscess, a granuloma or a cyst. Surprisingly, these three treatments using formocresol (FC: containing 40% formalin, etc.) and Calvital® (CV: containing 78.5% Ca(OH)2 and 20.0% iodoform, etc.), can frequently bring about the rapid, complete regeneration of reparative hard tissues (e.g., reparative dentin and alveolar bone) in the resorbed and nonresorbed areas of the above-mentioned lesions, and so biologically desirable healing.
On the present therapy as introduced in this review, the procedures, techniques, radiographic findings and evaluations by means of clinico-radiographic follow-up examinations for 6 to 75 months postoperatively were shown. Moreover, the healing mechanism on the present lesions and the clinical significance were discussed. These results suggest that the present therapy enables many clinicians to relieve a lot of primary teeth requiring some sort of endodontic therapy from the premature loss of them.View full abstractDownload PDF (2140K) -

JOURNAL FREE ACCESSChildhood has been recognized as a high-risk period for traumatic dental injuries. During the growth and development period, pediatric dental trauma requires special attention. Moreover, long-term follow-up and monitoring are essential. A traumatic dental injury often occurs as combination injuries of tooth, pulp, and periodontal ligaments. So, treatment of traumatic dental injuries is a complex and very difficult task.
Traumatic injuries to teeth occur frequently at from 1 to 3 years of age in primary dentition, and from 7 to 9 years of age in mixed dentition. In addition, the types of injuries differ between primary dentition in and mixed dentition.The characteristic types of trauma are instruction and displacement. On the other hand, the most likely type of injury becomes fractures from 8 years of age.
In primary dentition, treatment must consider effects on not only the traumatic primary teeth but also permanent successors, so procedures for permanent dentition are necessary. Also, fractures involving pulp occur frequently in the immature permanent teeth. In these cases, the treatment for dental root formation and root apical barrier formation is necessary.
Moreover, developmental and mineralization defects were found in about 40% of the permanent successors of the children who had been injured in the primary dentition. Long-term observations of the traumatic injuries teeth are necessary for the eruption of the permanent successors and normal root development.
In this paper, I suggest the characteristics and treatment of traumatic injuries to primary and immature permanent teeth.View full abstractDownload PDF (874K) -

JOURNAL FREE ACCESSOverview
Oral Habits (OH) such as thumb sucking, nail-biting, lip-biting habits, tongue thrusting, mouth breathing, and grinding of teeth, etc. adversely affect occlusions and oral and/or maxillofacial functions.
The causes of OH differ depending on the mental growth and developmental stage of the children. However, in patients of primary school age and older there is often an association with psychological problems related to family and school, etc. which can be pointed out, and it is very difficult to stop OH. For the treatment of malocclusions for which such OH have been confirmed, it is important to first carefully clear away the causal factors, and thus stop these OH through support and guidance.
Therefore, we have introduced a new support system for stopping OH using methods and protocols adopted at the Ohno Pediatric Orthodontic Dental Clinic (the Ohno Oral Habit Stopping System), which treats malocclusions with respect to oral habits closely associated with psychological problems, based on the scientific behavioral study of children.

V Clinical and statistical considerations regarding the Ohno Oral Habit Stopping System
VI Discussion
Before adopting the new Ohno Oral Habit Stopping System at our clinic, OH was handled only as a part of the treatment for malocclusions, so there were no satisfactory results regarding a support system for stopping such habits. Sometimes OH itself was overlooked. There are cases in which OH is greatly affected by psychological factors. Such cases need to be considered according to the child's circumstances, and by providing understanding and care for the child.View full abstractDownload PDF (3679K)

JOURNAL FREE ACCESSWe report a rare case of ductal papilloma from buccal mucosa minor salivary grand. A 80-year-old male patient visited our hospital with chief complaint of a mass in the left buccal mucosa. He had noticed the mass before 7 years, but left it. MRI and US imaging suggested that the mass had a clear and smooth margin. A clinical diagnosis of a benign tumor was made, and the tumor was removed with the patient under general anesthesia. The excised specimen was histologically diagnosed as intraductal papilloma of minor salivary gland.View full abstractDownload PDF (766K)
