This article aims to evaluate different methods and techniques published in the literature for tripodization in removable partial dentures. The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Electronic databases like PubMed, Cochrane Library, and Science Direct were searched for manuscripts published till August 15, 2021. An electronic search was restricted to the English language of the publications to identify the relevant articles on tripoding techniques in removable partial dentures. A hand search was also carried out. A total of 18 articles were included in this systematic review. The documented 18 articles associated with the tripoding techniques were reviewed systematically. Accurate repositioning of a cast on the surveyor is a critical step in the fabrication of a removable prosthesis. Based on the ease of use and no modifications to the existing cast, the "tripoder attachment" and "swiveling device" can be concluded to be superior to others. Once constructed, these devices are easy to use, can be operated for various patients, do not modify or damage the cast, and can be stored and disinfected for repeated use.

Background: The selection of shade of a tooth is a routine practice for a dentist, especially a prosthodontist, to make esthetically pleasing prostheses. The phenomenon of colour is a matter of perception by the eye. Every opaque object receives light, absorbs some of it and reflects the rest. A tooth being an opaque object, reflects some amount of light. The dominant wavelength of this reflected light is discerned by us as the colour of the tooth. Light has variable properties that influence our perception. Daylight is regarded as the standard source for the selection of the colour of a tooth. Conversely, the lack of optimal circumstances during different times of the day necessitates using artificial illuminants to select shade of a tooth. This study was carried out to compare the accuracy of a shade-matching light (SMILE LINE) to that of standard daylight.  Methods: This study followed the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines for cross-sectional studies. The study comprised 125 participants of ages ranging from 20 to 30 years. Five observers from the Department of Prosthodontics, Sharad Pawar Dental College (SPDC), Wardha selected the shade of the maxillary central incisor of 125 subjects under sunlight, dental operatory light, and shade-matching light. The statistical analysis was performed using the SPSS software, and Kappa statistics were used to compare the shades selected by the shade-matching light and dental operatory light with sunlight. Results: A strong correlation was discovered between the shades of tooth selected under the shade matching light and shades selected under sunlight for four out of five observers. Conclusions: The shade correcting device gives shades comparable to those selected under sunlight in ideal conditions making it useful as an alternative to sunlight for shade selection.
