The peripheral giant cell granuloma is a tumour like growth of the oral cavity. It has an unknown aetiology but believed to be a reactive lesion caused by local irritation or trauma. This article reports a case of peripheral giant cell granuloma in the edentulous region of the left posterior maxilla in a 35-year-old female patient. The lesion was sessile, measuring more than 15x15 mm in size, colour matching the adjacent mucosa involving the edentulous area distal to left upper second premolar extending till the edentulous region of the second molar. The radiograph shows peripheral cuffing of the bone. An excisional biopsy was performed. Histopathological appearance shows a fibro cellular stroma with numerous proliferating multinucleated giant cells scattered throughout the lesion. A diagnosis of peripheral giant cell granuloma was given. The patient was followed up for a year with no recurrence.

Introduction: The contour of artificial crowns has and continues to be highly controversial. Much of the controversy centers on whether the gingival sulcus is really in need of protection from buccal and/or lingual convexities, or whether a flatter emergence profile affords "self-cleansing" muscle action. Evidence is reviewed in this part which suggests that over-contoured crown is probably more detrimental to gingival health than under-contoured crown. Objective: The purpose of this study was to evaluate the effects of modified crown contour (over-contoured and under-contoured) on periodontal health. Methods: This study was conducted in the department of Prosthodontics, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh for the duration of one and half year to find out the successful artificial crown contour that is harmonious with the periodontium. Selected mandibular molar teeth were prepared for full veneer crown. 50 patients (Group-A) whose full veneer crown was fabricated with under-contouring form and another 50 patients (Group-B) whose full veneer crown was fabricated with over-contouring form and cemented on respected teeth. Clinical examination and evaluation were done after three (3) weeks, six (6) weeks, three (3) months, and six (6) months of post prosthesis follow up period. Data were collected on the basis of following parameters like gingival index, periodontal index, periodontal pocket depth, and gingival recession in a predesign data collection sheet. Statistical analysis (Chi- Square Test and unpaired t-test) was done to find out the significance value (P<0.05). Results: It is observed that the result was highly significant (p<.001) between two groups regarding Gingival index and Periodontal index but not significantly difference regarding Periodontal pocket depth or Gingival recession. Conclusion: This study revealed that under-contoured restoration does not produce any significant changes in the health of gingiva but over-.......

The purpose of this study was to evaluate the treatment outcome of Twin Block functional appliance and to determine the skeletodental, soft tissue and TMJ changes concurrent with the treatment. Ten subjects 5 males and 5 females with age ranged from 9 to 11 years were used in this study. All the cases showed Angle's Class II division 1 malocclusion due to mandibular retrusion. For each case out of the ten, lateral Cephalometric x-ray, right and left tomographic X-ray were done before and after treatment. On the base of the data obtained from this study both skeletodental and soft tissue improvement were detected after treatment. Also a significant reduction of the posterior joint space with significant increase of the condylar head thickness was seen. These outcomes make the appliance very effective in cases with retrognathic mandible, orthognathic maxilla and normal incisors inclination.

There have been considerable advances in the field of dentistry in the past few decades. Such advances have led to better imaging tools for more accurate diagnosis and comprehensive treatment planning. Conventional radiographs with 2-dimensional (2D) imaging methods such as periapical radiographs, lateral cephalograms, and panoramic cephalograms have been used since a long time. Earlier such radiographs were recorded with film-based radiographic technique. These radiographs have been shifted to digital radiography with the advances in technology, which has led to a substantial decrease in the time required for procedures for image processing, viewing, and storage. Recently, the 3-dimensional (3D) radiographs such as Computed Tomography (CT) and Cone-beam computed tomography (CBCT) have changed the landscape of dental imaging. This paper discusses in detail the current available methods of dental imaging.
