Position of parotid papilla and commissure of lip in relation to maxillary occlusal plane among patients visiting a tertiary care centre of Nepal (1 - 6)
Introduction: Exact position of Parotid papilla and commissure of lip plays crucial role in determiningmaxillary occlusal plane which directly facilitates in rehabilitating edentulous patients with removablecomplete denture. Since the beginning many authors have conducted different studies regarding itsposition but multiple variations in its location have been noted. Also this type of study has not beenconducted in Nepalese population which drags urge to determine the position of these soft tissuelandmarks in context to Nepalese population.
Objective: To determine the position of parotid papilla and commissure of lip in relation to maxillaryocclusal plane.Materials and Methods: A descriptive cross-sectional study was conducted in the 45 dentate subjectsvisiting Nobel medical college from November 2019 to April 2020. A vestibular impression was made,stone index fabricated and vernier caliper was used to locate position of parotid papilla & commissureof lip. All the data were collected and statistically analyzed.
Results: The mean measurement of distances between maxillary occlusal plane and parotid papillawas 3.69 ± 1.19 mm and between maxillary occlusal plane and commissure of lip was 0.41 ± 0.83 mmrespectively.
Conclusion: This study showed that position of parotid papilla was superior to the position of maxillaryocclusal plane with the mean distance of 3.69mm. Commissure of lip was found to be at the levelof maxillary occlusion plane in highest number of cases followed by superior position with least atinferior position with respect to maxillary occlusal plane.
