Closure of Diastema and Gingival Recontouring Using Direct Adhesive Restorations: A Case Report

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. The conditioning of the interdental papilla is a simple, direct, predictable, and low-cost alternative. This paper reports a case on diastema closure in anterior teeth that was successfully treated using gingival recontouring and composite resin restorations.

CLINICAL SIGNIFICANCE

The closure of diastemas in anterior teeth using direct adhesive restorations and gingival recontouring is a viable option for the clinician because it restores esthetic harmony between soft and hard tissues.     

Phenytoin-Induced Gingival Overgrowth Resulting in Delayed Eruption of the Primary Dentition: A Case Report

A case of delayed eruption of the primary dentition secondary to Phenytoin therapy in a 4-year-old child is reported. The patient had been on phenytoin therapy since the first months of life. Radiographs revealed that alveolar but not gingival emergence had occurred. Surgical excision of the excess gingival tissue was accomplished under general anesthesia. Oral hygiene procedures were stressed and parental cooperation solicited. Three- and ninemonth postoperative visits revealed no regrowth of gingival tissue and continued eruption of the primary dentition.     

胃腺癌牙龈转移的病例报告及文献复习

目的:探讨1例胃腺癌牙龈转移的诊断、治疗及预后情况,为临床上胃癌合并口腔肿物患者的诊断提供参考。方法:报道扬州大学附属苏北人民医院1例胃腺癌牙龈转移患者的临床表现、治疗过程及预后情况,同时结合文献对此类病例的临床特点与诊治进行回顾分析。结果:患者因“右侧下颌后牙区牙龈肿块6个月”来我院就诊,确诊胃腺癌病史1个月。经口腔活检,结合病史考虑为转移性腺癌(牙龈)。收入院后,择期行手术切除牙龈转移瘤,并进行术后化疗。患者目前伤口愈合良好。临床上此类患者较少见,一般胃癌发生口腔转移多为疾病晚期,预后较差,生存时间较短。结论:胃腺癌合并口腔转移病例在临床上较少见,其准确诊断应多结合病史、影像学及病理结果,患者多处于癌症晚期,预后一般较差。临床上对于胃癌患者的口腔肿物需予以重视,避免误诊。

Gingival Perfusion and Tissue Biomarkers During Early Healing of Postextraction Regenerative Procedures: A Prospective Case Series

Background: Postextraction alveolar bone loss, mostly affecting the buccal plate, occurs despite regenerative procedures. To better understand possible determinants, this prospective case series assesses gingival blood perfusion and tissue molecular responses in relation to postextraction regenerative outcomes. Methods: Adults scheduled to receive bone grafting in maxillary, non‐molar, single‐tooth extraction sites were recruited. Clinical documentation included the following: 1) probing depth (PD); 2) keratinized tissue width (KT); 3) tissue biotype (TB); and 4) plaque level. Wound closure was clinically evaluated. Gingival blood perfusion was measured by laser Doppler flowmetry (LDF). Wound fluid (WF) and gingival biopsies were analyzed for protein levels and gene expression, respectively, of relevant molecular markers. Bone healing outcomes were determined radiographically (cone‐beam computed tomography). Healing was followed for 4 months. Results: Data from 15 patients are reported. Postoperatively, neither complications nor changes in PD, KT, or TB were observed. LDF revealed decreased perfusion followed by hyperemia that persisted for 1 month (P ≤0.05). WF levels of angiopoietin‐2, interleukin‐8 (IL‐8), tumor necrosis factor‐alpha (TNF‐α), and vascular endothelial growth factor peaked on day 6 (P ≤0.05) and decreased thereafter. Only IL‐8 and TNF‐α exhibited increased gene expression. Linear bone changes were negligible. Volumetric bone changes were minimal but statistically significant, with more bone loss when membrane was used (P = 0.05). Conclusions: Gingival blood perfusion after postextraction bone regenerative procedures follows an ischemia‐reperfusion model. Transient increases in angiogenic factor levels and prolonged hyperemia characterize the soft tissue response. These soft tissue responses do not determine radiographic bone changes.     

Guided Tissue Regeneration in Class IV External Cervical Resorption: A Case Report

External cervical resorption (ECR) is a type of dental resorption that originates from the loss of the cementum's protective layer. The direct exposure of dentin to the periodontal ligament may lead to the invasion of clastic cells through an entry point on the external root surface into the dentinal tissue, causing resorption. Depending on the extension of ECR, different treatments are proposed. Although the literature presents distinct materials and methods for restoring ECR areas, an existing gap is related to care in the treatment of the supporting periodontal tissue. Guided tissue regeneration (GTR)/guided bone regeneration includes the stimulation of bone formation in bone defects using different types of membranes (resorbable and nonresorbable), regardless of its association with bone substitutes or grafts. Despite the benefits of guided bone regeneration, the application of this method in cases of ECR is still under-explored in the literature. Thus, the present case report uses GTR with xenogenic material and polydioxanone membrane in a case of class IV ECR. The success of the present case is related to the correct diagnosis and treatment plan. Complete debridement of resorption areas and restoration with biodentine were effective in tooth repair. GTR contributed to the stabilization of supporting periodontal tissues. The association of the xenogeneic bone graft with the polydioxanone membrane proved to be a viable option for restoring the health of the periodontium.     

At-Home Bleaching System: Effect on Gingival Tissue

This study evaluated the effects of an at-home vital bleaching system on gingival responses over a 6-week period. Objective measures were utilized to measure and monitor gingival inflammation over this period of time. Vital bleaching was performed as follows: (1) bleaching gel in a prefabricated mouthguard and (2) an ad-mix technique – bleaching gel and toothpaste in a 1:1 ratio. In addition a control group used a placebo in a prefabricated mouthguard. The at-home vital bleaching system produced no adverse gingival tissue responses. Furthermore, the at-home vital bleaching system helped produce a therapeutic effect on inflamed gingival tissues over the course of the study.     

Glossodynia: A Case Report

The migraine headache is a common form of head and neck pain, which varies in its clinical expression, the factors that cause it, and the therapeutic approaches to its treatment and prevention. Although thought to be vascular in nature, the migraine has a considerable muscular component that is involved in its painful sequelae. Since at present there seems to be a continuum between migraine and muscular headache, the occlusal splint may prove to be an important therapic adjunct in treating migraine's painful sequelae.

Clinical Evaluation of Three New Gingival Retraction Systems: A Research Report

The purpose of this study was to evaluate the clinical efficacy of 3 new gingival retraction systems; Stay-put, Magic foam cord and expasyl, on the basis of their relative ease of handling, time taken for placement, hemorrhage control and the amount of gingival retraction. Thirty subjects were selected requiring fixed prosthesis. The 3 gingival retraction systems were used on the prepared abutments randomly. The time taken for placement of each retraction system was recorded. The vertical gingival retraction was measured before and after retraction using flexible measuring strip with 0.5 mm grading. The horizontal retraction was measured on polyether impressions made before the retraction and after retraction. Based on the results, magic foam cord retraction system can be considered more effective gingival retraction system among the three retraction systems used in the study.     

Gingival Recessions and Noncarious Cervical Lesions: A Soft and Hard Tissue Challenge

Abstract: Gingival recessions and noncarious cervical lesions are frequent and closely related defects which can be successfully treated by mucogingival surgery and restorative therapy techniques either used alone or in combination depending on the defect characteristics. Proper treatment planning is guided by careful clinical diagnosis. A selection of treatment modalities are presented and useful hints proposed: the long term success is always strictly bound to the identification and elimination of the ethiologic factors, to a correct treatment and a meticulous maintenance program.
