Abstract
Oral squamous cell carcinomas (OSCCs) fall between the sixth and eighth most common cancers. The prevention of cancer and the treatment of the disease depends on early diagnosis. To encourage dental professionals to use light-based detection techniques in clinical practice, this systematic review aims to evaluate the literature on the effectiveness of chemiluminescence and autofluorescent imaging equipment in the detection of OSCC and OPMDs. PUBMED [MEDLINE] and SCIENCE DIRECT were the electronic databases and retrieval systems used to look for pertinent articles. Search terms like"oral cancer,""early diagnosis,""potentially malignant disorders,"chemiluminescence," autofluorescence," and "VELscope" were used to search the database of indexed journals. 26 articles in total have been chosen for this review. The majority of the research was cross-sectional. Chemiluminescence and Autofluorescence can help a skilled doctor spot oral premalignant lesions with the autofluorescence technique being superior and the way for biopsies within the altered mucosa.
