The incidence of tuberculosis is a frequent finding especially in developing countries owing to a significant population of the people belonging to the lower socioeconomic strata with poor hygiene and nutrition. Tubercular involvement of the paranasal sinuses is usually asymptomatic until it reaches an advanced state and when it involves the maxillary sinus, this initial period of quiescence often mimics the clinical presentation of a chronic sinus infection, which often leads to a diagnostic dilemma. Symptoms commonly reported are chronic sinusitis and rhinorrhea, both of which being nonspecific in nature leading to a quandary. We herewith present a 50-year-old patient who presented with symptoms of an odontogenic infection involving the right maxillary molars. Primary management did not yield to the resolution of presenting symptoms. On biopsy, through an endoscopic approach and subsequent histopathological examination, the diagnosis of tuberculosis was arrived at. The patient responded well to antitubercular drug therapy.

The direct sinus lift approach is a well-established technique for implant placement in the deficient maxilla. The need to provide efficacious treatment to patients while minimizing procedure-associated morbidity lead to the introduction to bone substitutes as alternative to autogenous bone grafting for bone augmentation in the sinus.Calcium phosphosilicate biomaterial is the form of morsels that have been recently introduced for use in oral surgery. The osteostimulative properties of this biomaterial makes it an excellent bone substitute for indications that have been traditionally treated with autogenous bone graft.A case is presented where implant rehabilitation was planned in left maxillary posterior region with pre-existent significant pneumatization of the sinus. Under local anesthesia direct sinus lift technique was employed. The results were highly satisfactory showing regeneration up to approximately 13 mm of bone height that allowed successful implant placement of appropriately sized implant fixtures.The present case-study is a proof-of-principle study of the efficacy of morsels in direct sinus lift. Use of morsels for sinus augmentation provides successful outcomes with minimal morbidity for the patient and significant decrease in chair-side time that would be required for harvest of an autograft.

One of the most often utilized building materials is concrete, yet it is prone to cracking. The structure is far more prone to fail due to cracks. There are several methods for, but they are not permanent and are not environmentally friendly. The inclusion of microorganisms in concrete can be a long-term option for crack healing or filling. It also influences the compressive and split tensile strength and maintain strength after crack formation to certain amount. Calcium Carbonate (Lime) production prevents cracks from recurring in the same location and serves as a permanent and long-term treatment. From the results obtained, it could be concluded that the product is more durable and requires less maintenance.
