Purpose: The aim of this study was to evaluate alterations of papilla dimensions after orthodontic closure of the diastema between maxillary central incisors. Methods: Sixty patients who had a visible diastema between maxillary central incisors that had been closed by orthodontic approximation were selected for this study. Various papilla dimensions were assessed on clinical photographs and study models before the orthodontic treatment and at the follow-up examination after closure of the diastema. Influences of the variables assessed before orthodontic treatment on the alterations of papilla height (PH) and papilla base thickness (PBT) were evaluated by univariate regression analysis. To analyze potential influences of the 3-dimensional papilla dimensions before orthodontic treatment on the alterations of PH and PBT, a multiple regression model was formulated including the 3-dimensional papilla dimensions as predictor variables. Results: On average, PH decreased by 0.80 mm and PBT increased after orthodontic closure of the diastema (P<0.01). Univariate regression analysis revealed that the PH (P=0.002) and PBT (P=0.047) before orthodontic treatment influenced the alteration of PH. With respect to the alteration of PBT, the diastema width (P=0.045) and PBT (P=0.000) were found to be influential factors. PBT before the orthodontic treatment significantly influenced the alteration of PBT in the multiple regression model. Conclusions: PH decreased but PBT increased after orthodontic closure of the diastema. The papilla dimensions before orthodontic treatment influenced the alterations of PH and PBT after closure of the diastema. The PBT increased more when the diastema width before the orthodontic treatment was larger.

There are orthodontic closure, surgincal closure, prosthetic solution in the treatment of diastema. The orthodontic closure has been widely used owing to its conservative nature, but retention after treatment has been difficult and problematic. So, authors observed relapse and retention after the orthodontic closure of 3 diastema cases. The results might be summarized as follows : The space that had been approximated between central incisors, was reopened by the use of retention appliance which did not join two central incisors together though fixed prothesis. By the frenectomy, circumferential supracrestal fibrotomy and lingual bonded retainer which joined two central incisors together after the orthodontic closure of diastema, were good results obtained. The frenectomy, fibrotomy, and the fixed retention appliance which joined two central incisors together must be needed after the orthodontic closure of diastema.

Diastema is thought to be a problem related to aesthetics, pronunciation, or malocclusion. Due to its extent and patient conditions, orthodontic treatment, prosthodontic treatment, and conservative direct resin restoration are the treatment options for diastema closure. Additional factors need to be considered when deciding on the most appropriate treatment of diastema, particularly for patients with cerebral palsy. A 13-year-old girl visited the Department of Pediatric Dentistry at Yonsei University Dental Hospital with a chief complaint of the large gap between her upper front teeth. After clinical and radiographic examinations, midline diastema of 4.5 mm, protrusive maxilla incisors, congenital missing teeth, retained primary teeth, etc. were identified. Prosthodontic treatment with intentional root canal treatment was not appropriate because of the patient's age. Dental spaces can be closed effectively via orthodontic appliances. However, additional prosthodontic and restorative intervention is unavoidable, which incurs significant costs and requires more time. Instead of orthodontic and prosthodontic treatment, direct resin restoration can address the chief complaint; these restorations are reversible, less harmful to other oral structure and teeth, relatively easy to apply, less expensive than other treatments, and require shorter office visits. Midline diastema can be treated in several ways. For diastema closure in patients with cerebral palsy, conservative resin restorations are a short, simple, and appropriate treatment compared with orthodontic or prosthodontic treatments.

Many references report that abnormal diastema except temporary diastema existing in mixed dentition period is caused by maxilary heavy labial frenum, malocclusion, progressive periodontal disease, and loss of posterior teeth. We can diagnose patient as diastema caused by periodontal disease, especially, in case of accompanying progressively destructed anterior maxillary alveolar bone defect, and interseptal bone defect. We report Multiple disciplinary approach for diastema associated with periodontal disease. Periodontal treatment(Guided Tissue -Regeneration, alveoloplasty, bone graft), or thodontic treatment (space closure, redistribution), and the final proshodontic restoration for retention were used.

One of the most challenging task in closing anterior diastema is avoiding "black triangle" between the teeth. This paper reports a case that the closure of diastema in anterior teeth could be successfully accomplished using direct adhesive restorations and gingival recontouring. The traditional technique using Mylar strip was modified to increase the emergence profile with natural contours at the gingival-tooth interface. Mylar strip was extended out of the sulcus by approximately 1 mm high from the gingival margin, and a small cotton pellet was used to provide the emergence contour. This modified approach is acceptable for the clinical situation.

Adenomatoid odontogenic tumor (AOT) is a rare, asymptomatic, slow-growing benign tumor that can be divided into three variants: follicular, extrafollicular, and peripheral. By treating AOT using an enucleation and curettage approach, recurrence can be avoided. We report a case of a 24-year-old female who presented with a lump in the right mandibular premolar area along with diastema between displaced teeth #43 and #44 and was diagnosed with extrafollicular AOT. The patient was managed with enucleation-curettage surgery without additional bone graft procedure along with routine follow-up. A successful outcome without recurrence was achieved, and diastema closure with repositioning of the displaced teeth did not require orthodontic treatment. AOT should be managed via enucleation and curettage to obtain successful outcomes without recurrence. Spontaneous bone regeneration following enucleation can be achieved without guided bone regeneration. Also, diastema closure and repositioning of displaced teeth can occur without orthodontic interventions through physiologic drift.

Closure of interdental spaces using proximal build-ups with resin composite is considered to be practical and conservative. However, a comprehensive approach combining two or more treatment modalities may be needed to improve esthetics. This case report describes the management of a patient with multiple diastemas, a peg-shaped lateral incisor and midline deviation in the maxillary anterior area. Direct resin bonding along with orthodontic movement of teeth allows space closure and midline correction, consequently, creating a better esthetic result.

Anterior diastemas are common esthetic problems. One of the challenges in clinical esthetic dentistry is closing anterior diastemas without creating "black triangles" between the teeth. The success of a restorative treatment in anterior teeth depends on the esthetic integration between soft tissues and hard tissues. This report describes the successfully accomplished diastema closure case by producing the emergence profile with natural contours at the gingival-tooth interface and then generating of gingival recontouring process.
