Introduction Oral Squamous Cell Carcinomas have been considered as the most prevalent malignancies in the head and neck region and are frequently undiagnosed until symptomatic with an advanced stage of disease. So there is an urgent need to device methods for the detection of oral premalignant lesions and oral cancer at an early stage in order to improve the survival rate for patients. A number of tests have been done for the detection of oral cancer which include oral brush biopsy, the Vizilite, oral autofluorescence including chemiluscence, photodynamic detection, toluidine blue staining, methylene blue staining, incisional biopsy and many more. Material The article reviews various diagnostic modalities available at present for detection of squamous cell carcinomas and oral epithelial dysplasias based on advanced PUBMED search of the English language literature from the year 1972 to present in order to help us select the most suitable among them fulfilling the desired criteria of being non-invasive, highly specific and sensitive, economically viable, having a scope to be used for mass screening, easy to process, having low inter examiner variability and possibly not requiring high expertise to conduct and interpret the results. Conclusion After reviewing various diagnostic modalities, we conclude that toluidine blue staining emerges as a clear winner among all these and it can act as a valuable adjunct to incisional biopsy in detection of oral cancer and may not substitute it except in certain circumstances when its results are carefully correlated with the patient history and clinical characteristics of the mucosal disorder, considering the fact that incisional biopsy has been reported to cause dissemination of cancer cells in the circulation there by increasing the possibility of metastasis. We must emphasize that toludine blue is a screening modality and not a diagnostic procedure like biopsy and hence cannot replace a confirmatory biopsy as a whole

CRP displayed a more consistent relation with clinical severity of the infection than TLC. Hence it could be more reliably employed to judge the progress in a patient with OSI.

Background: In the rehabilitation of atrophic posterior maxilla, factors such as age, extraction of teeth result in loss of alveolar bone height together with increased pneumatization of sinus contradicting the implant surgery. Although adequate bone height can be achieved using various maxillary sinus augmentation techniques, these procedures have been practiced successfully. However, significant complications occur such as perforations or tearing. To maintain the integrity of Schneiderian membrane subsequently increasing the success rate a retrospective analysis is carried out on various techniques with complications which occur during and after treatment.Methods: A systematic online and manual review of the literature identified articles dealing with SFE. Applying rigid inclusion criteria, screening and data abstraction were performed independently by two reviewers. The follow-up of was a minimum of 6 months. The articles selected were carefully read and data of interest were tabulated. The identified articles were analyzed regarding implant outcome, with or without graft using different surgical techniques with complication rates using random-effects Poisson regression models to obtain summary estimates/ year proportions. This article reviews various sinus lift techniques for intact elevation of Schneiderian membrane based on advanced PUBMED, Medline, Cochrane database system search of English-language literature from the year 2004 to present in order to compare and evaluate the success rate with minimal complications selecting the most suitable which can fulfill the criteria of being non-invasive, less time-consuming, more reliable and less traumatic.Result:After reviewing various sinus elevation techniques; nasal suction technique(NaSucT), balloon antral elevation technique(BAOSFE), and Hydraulic Sinus Lift technique(HySiLift) emerges as more favourable among all these and can efficiently lift the Schneiderian membrane with minimal trauma. We must emphasize that these are new techniques and cannot replace the conventional techniques as a whole.
