    Plasma cell gingivitis: A unique gingival lesion of unknown etiology

    Get PDF
    Gingival overgrowth is a common feature of gingival diseases, and it represents an exuberant response of the tissues to a variety of systemic and local factors. Plasma cell gingivitis (PCG), an uncommon, non-malignant lesion, is often characterized by an off ending allergen which causes a dense infi ltration of plasma cells in connective tissue. Soft tissue biopsy of affected and normal tissues is necessary for confi rmatory diagnosis.The significance of this lesion is that it may cause severe gingival infl ammation, discomfort, and bleeding with minimal trauma and may resemble more serious conditions. Here is a case of a 34-year-old female patient who presented with a solitary diff use gingival enlargement in mandibular anterior region. Overgrowth was multilobular, erythematous smooth and glossy in appearance, semicircular, non-tender with a sessile base which first gave the impression of pyogenic granuloma. The overgrowth was surgically excised and subjected to a histopathological examination that revealed a predominant plasma cell infi ltrate admixed with few neutrophils, lymphocytes, and eosinophil suggestive of PCG. The patient has been kept on follow-up and post-operatively there has been no recurrence of the lesion until date

    ABSTRACT  The Green tea is obtained from the tea plant Camellia sinensis (L.), Common names: Green tea extract, Chinese tea which belongs to the family Theaceae. Tea is the most consumed drink in the world after water. Green tea is a ‘non-fermented’ tea, and contains more Catechins, than black tea or oolong tea. Catechins are in vitro and in vivo strong anti-oxidants. In addition, its content of certain minerals and vitamins increases the antioxidant potential of this type of tea. It is a widely used medicinal plant by the trials throughout India, China and popular in various indigenous system of medicine like Ayurveda, Unani and Homoeopathy Green tea has been consumed throughout the ages in India, China, Japan, and Thailand. Recent human studies suggest that green tea contributes to overall oral health. Green tea has been used in dentistry and has a promising role in future. This paper is an attempt to review potential role if green tea in promoting oral health

    3D virtual planning of temporomandibular joint ankylosis using computed tomography a case report in a 4-year-old female patient

    Ankylosis is a Greek word meaning a stiff joint. Temporomandibular joint (TMJ) ankylosis is the development of complete or incomplete limitation of movement of the TMJ by bone or fi brous tissue. The etiology and treatment of TMJ ankylosis have been well documented in the literature, with trauma and infection being the leading causes.Radiographically, ankylosis presents features that facilitate the diagnosis. However, its visualization is not precise involving conventional radiographic technique. With the evolution of radiographic techniques, computed tomography (CT) became an essential tool in the diagnosis of the ankylosis of TMJ and presented a valid reconstructed image of an ankylosis. The aim of this paper is to report a case of TMJ ankylosis in a 4-year-old girl and describe the importance tomographic images related ankylosis of TMJ by threedimensional (3D) CT, using several slices as axial, coronal, and 3D reformatted images as a guide for presurgical treatment planning of an ankylosis

    Neutral Zone approach for severely atrophic ridges; Avenues beyond implants and surgeries – A Case Report

    Get PDF
    One of the most common problems encountered among long term denture wearers is the reduction in the denture foundation. Prosthodontic Rehabilitation of a patient with severely resorbed ridge is the most challenging therapy a prosthodontist can undertake. In order to have a favourable prognosis for the denture therapy, impression technique selected should be based on the present state of the basal tissue support. This article presents the application of neutral zone (NZ) concept being incorporated in to impression making procedure in an effort to achieve successful complete denture therapy

    Assessment of apical leakage of different endodontic sealers -In vitro study

    Get PDF
    Aim: The aim of this prospective study was to assess in vitro the comparison between apical leakage of Apexit Plus (calcium hydroxide based), Roth 801 (Zinc oxide eugenol based) and Perma Evolution (epoxy resin based) sealers in lateral condensation technique using linear dye leakage penetration method.Material and methods: In this study 70 freshly extracted maxillary central incisors and canines with straight root canals were used. Teeth were decoronated and step back root canal preparation using Gates Glidden drill and stainless steel hand K files was performed with size 45 being the master apical cone. After preparation, the teeth were randomly divided into 5 groups. Three groups with 20 teeth for experimental and two groups with 5 teeth as positive and negative control. Obturation was done with lateral condensation in three groups with Roth 801, Apexit plus and Perma Evolution sealers. The obturated specimens were then stored in 2% Basic fuchsin dye for 72 hours. After splitting the teeth longitudinally, each tooth has been placed on a standardized scaled paper under the microscope and digital images have been captured by this microscope. Then the digital images were processed by Analyzing Digital Image software.Results: The results showed that Roth 801 sealer leaked significantly higher than both Apexit plus and Perma Evolution sealers (p < 0.05) and no statically significant difference has been found between Apexit plus and Perma Evolution sealers (p > 0.05).Conclusion: According to the methodology proposed and based on the results of this study, it may be concluded that Roth 801 showed the most leakage but Perma Evolution and Apexit plus showed similar sealing ability. However, further in vivo studies requirement should be done to find the best root canal filling material

    Dermatoglyphics-A New Diagnostic Tool in Detection of Dental Caries among Deaf and Mute Children

    Get PDF
    Introduction: Dermatoglyphics is the study of dermal ridge configurations on palmar and plantar surfaces of hands and feet. Dermal ridges and craniofacial structures are both formed during 6-7th week of intra-uterine life, therefore hereditary and environmental factors leading to dental caries may also cause peculiarities in fingerprint patterns. Objective: This study evaluates the dermatoglyphic peculiarities and caries experience of Deaf and Mute children. Design: A total of 100 school children aged 6-16 years were selected using purposive and simple random sampling. Their fingerprints were recorded with duplicating ink and caries experience was clinically assessed by dmft/DMFT index.                                                                                        Results: Mann-Whitney test revealed statistical association between whorl patterns and loop patters in caries and caries free group (P<0.001). The frequency of whorls was found to be more in caries group and the frequency of loops more in caries free group. Conclusion: Dermatoglyphics could be an appropriate method to explore the possibility of a non-invasive and an early predictor for dental caries and hearing impairment in children so as to initiate the preventive oral health measures at an early age

    Tooth loss has a negative impact on masticatory function, aesthetics, and self-image.  Fixed partial dentures, removable partial dentures, complete dentures, and implant-supported dentures can replace missing teeth, but it is not known whether they differ in their ability to reconstruct the masticatory force and preservation of residual bone ridge.  An overdenture is a complete or removable partial denture that has one or more abutment tooth or implants to provide a support.   Moreover the shortened crown also changes the crown to root ratio thus the reduced mobility of the tooth facilitate ridge preservation, improves the bone support.   Overdentures maintain proprioception of teeth and improve stability and retention.  Overdenture is preventive prosthodontics concept involving the multidisciplinary approach involving periodontic, endodontic & prosthodontics intervention. Prefabricated attachments are versatile and  provide considerable retention and stability.This case report of patient with few teeth remaining has been treated with overdenture supported with preci-clix overdenture attachments
