"From mobility to stability" is what every Periodontist aims at. For centuries dentists have been trying to stabilize loose teeth. The periodontally compromised dentition offers many opportunities to debate the efficacy of splinting. It frequently addresses the therapeutic goals of treatment, including patient comfort with mastication and retention of teeth after orthodontic intervention. Dental splints that are properly placed and contoured enable effective patient self-care and contribute to a positive prognosis. Continued success cannot occur without scrupulous patient self-care. With the combination of proficient clinical skill, appropriate dental material selection, good communication and comprehensive health education, both providers and patients can benefit from aesthetic, functional and healthy dental splints. We hope that these notes will provide a straightforward theoretical base on which the post-graduate and undergraduate may build knowledge on mobility and splinting and develop an interest in the speciality of Periodontics.

One of the major problems in studying dental diseases and its factors is the development of a suitable, practicable method for recording and classifying the occurrence and severity of the disease. Lord Kelvin once stated that, "until you can count it, weigh it, or express it in Quantitative fashion, you have scarcely begun to think about the problem in a scientific fashion."Dental index can be considered as the main tool of epidemiological studies in dental diseases, to determine the incidence, prevalence and severity of the diseases based on which preventive programmes are adopted for their control and prevention. This manuscript is an attempt to make an update on indices used in oral diseases and will be useful to the professionals who are involved in research projects.
