The implication of understanding medico legal aspect in dentistry does not rest only with its use in dental practice. The understanding also plays a vital role in dental public health programmes. Understanding of medico legal aspect provides protection against commercial, legal and medico legal litigation. It provides a practical implication of understanding the theoretical aspect of medical and dental history, chart notes, radiographs, photographs and models, because, legally, dentist written records carry more weight than the patient's recollections.
