Peripheral ossifying fibroma (POF) is one of the inflammatory reactive hyperplasia of gingiva. It represents a separate clinical entity rather than a transitional form of pyogenic granuloma and shares unique clinical characteristics and diverse histopathological features. The lesion occurs over a wide age range with females being affected more often than males. Furthermore, the POF has a propensity to occur in the incisor cuspid area affecting maxilla more than the mandible. POF is known to arise as a focal exophytic mass exclusively on the gingiva commonly appearing to originate from the interdentally gingiva and does not commonly involve the underlying bone. Irritation to the gingiva by calculus, plaque, ill-fitting dentures, and hormonal influence has been considered in the etiopathogenesis. Here, we represent a case report of 21 year old male patient with a solitary gingival enlargement in the left maxillary posterior region i.r.t 24, 25, 26. Patient gives the history of excision of enlargement one year before. The enlargement reappeared three months back. On current examination the lesion was approximately 1.2×1.5 cm size and was found to be reddish in color, irregular in shape, sessile, non-lobulated, firm in consistency and non-tender on palpation. On histological examination it was diagnosed as peripheral ossifying fibroma.

SARS-CoV-2 is one of the seven types of corona virus, which includes the ones that cause severe diseases like Middle East respiratory Syndrome (MERS) and Sudden Acute Respiratory Syndrome (SARS). As India is fighting with a deadly second wave of covid-19, cases of rare fungal infection called “Mucormycosis” are being reported across the country, adding to the worries. Mucormycosis, also known as black fungus is a serious fungal infection, usually seen in immune compromised patients, which spreads rapidly from nose and sinuses to face, jaw, eyes and brain. The management of such complication is by complete surgical debridement of orosinonasal, orbit facial, sin nasal and palate. Rehabilitation of such defects aims to restore the lost function, as well as psychological factor that present a challenge situation for the maxillofacial prosthodontist. Prosthodontic rehabilitation of such patients presents a significant challenge in restoring speech, deglutition, mastication, and respiration. Comprehensive management of these defects follows combination prosthesis comprising of orbital, nasal and obturator. The optimum retention for the prosthesis is usually retained by combination of anatomical, mechanical and functional factors. This paper is intended to highlight basic prosthodontic techniques for management of post Covid cases seen in mucormycosis.

Introduction: Traditionally, irreversible hydrocolloid (alginate) has been the material of choice for diagnostic impressions because it is inexpensive, hydrophilic, reasonably dimensionally accurate and easy to manipulate. Tearing in alginate impression can lead to inaccuracy of the gypsum model that forms the bases for prosthesis. This study was attempted to analyze the impact of water collected from different sources in relation to its hardness on the tear strength of commercially available alginate material and if water is an important factor in the tear strength of alginate. Additionally, authors also planned to assess the water hardness that would provide optimum tear strength to the alginate material.

Materials and Method: Ten samples of alginate in each group with water from different sources (tap water, mineral water, saline, distilled water) were taken. A Plexiglas mold was prepared, manipulated samples were poured in the mold, once set the samples were tested on Universal Testing Machine for ultimate tensile strength.

Results: The statistical result indicates that the alginate mixed with distilled water (10 samples each) shows better tensile strength followed by tap water, mineral water and saline. By comparing the mean tensile strength of the four groups, ANOVA showed significantly different tensile strength among the groups. The mean tensile strength of Group II was the highest followed by Group I, Group IV and Group III.

Conclusion: Maximum tear strength is indicated by the samples manipulated with the water having minimum dissolved salts i.e. distilled water.

Introduction: Composite resins are generally composed of Bis-GMA and other dimethacrylate monomers. Visible light curing resin-based composite help the dentist to assess the beginning of polymerization for each applied layer. Curing technology was regularly subjected to modifications during the last decades but meanwhile the LED era is fully established. This study was done to compare the efficiency of newer ultrahigh intensity LED with conventional LED.

Materials and method: Composite resin was used and poured into stainless steel molds (diameter 6 mm, height 3 mm). The total number of specimens was 10, i.e. 5 in group I and 5 in group II. Materials used in this study were: molds with a diameter of 6 mm and a thickness of 3 mm, plastic filling, a LCU with curing times of 1 seconds, a LCU with a curing time of 20 seconds, packable composite resin and a universal testing machine to measure the diametric tensile strength test.

Result: Mean Dia mitral tensile strength of Group I is 27.57 and standard deviation was 0.07 and for Group II mean is 19.31 and standard deviation was 0.07.Mean difference of tensile strength between Group I and Group II was 8.26 which was statistically significant at the 0.05 level of significance.

Conclusion: The degree of polymerization of the composite resin restoration may be affected by the type of LCU.

Malignancies are preceded by potentially malignant disorders. Leukoplakia is one of the precursors of oral squalors cell carcinoma. Leukoplakia is one of the types of potentially malignant disorder that have potential to convert into carcinoma frequently. Leukoplakia poses a major diagnostic and therapeutic challenge. We present a case of leukoplakia in left side of buccal mucosa which is converted into carcinoma in situ along with review in light of current information from the literature. We also attempt to present the clinical relevance, and the therapeutic modalities available for the management of the disease.
