Real-time fundus images captured to detect multiple diseases are prone to different quality issues like illumination, noise, etc., resulting in less visibility of anomalies. So, enhancing the retinal fundus images is essential for a better prediction rate of eye diseases. In this paper, we propose Lab color space-based enhancement techniques for retinal image enhancement. Existing research works does not consider the relation between color spaces of the fundus image in selecting a specific channel to perform retinal image enhancement. Our unique contribution to this research work is utilizing the color dominance of an image in quantifying the distribution of information in the blue channel and performing enhancement in Lab space followed by a series of steps to optimize overall brightness and contrast. The test set of the Retinal Fundus Multi-disease Image Dataset is used to evaluate the performance of the proposed enhancement technique in identifying the presence or absence of retinal abnormality. The proposed technique achieved an accuracy of 89.53 percent., (© 2023. The Author(s).)

Oral leukoplakia is one of the most common potentially malignant disorders. Right diagnosis of potentially malignant disorders may help to prevent these lesions from malignant transformation. Proper understanding, recognizing, identification and differentiating these lesions from normal mucosa are necessary for proper treatment.

Forensic dentistry or forensic odontology admits dentists' participation or identification of the victim and assisting legal and criminal issues. It refers to the proper handling, examination, identification and evaluation of dental evidence. This article summarizes the evolution of forensic odontology that started right from Garden of Eden to the modern scenario in identification of the gang rape case which happened in the state capital. Forensic dentistry plays a significant role in identifying the victims of crime, deceased individuals through the examination of anatomical structures, dental appliances and dental restorations.

Flavonoids include a huge group of naturally occurring organic compounds. It is found in a large variety of plants including fruits, seeds, grains, tea vegetables, nuts, and wine. Many studies have shown that there is a strong association between flavonoid intake and the long-term effects on mortality. It is widely used in dentistry and it has many clinical effects. This article summarizes the effects of flavonoids to humankind and its clinical applications in dentistry.
