“…Finally, the retainment of saliva by the anterior palate plays also a possible role. The structural orientation of the anterior palate, especially of the rugae with their irregular, asymmetric ridges [ 61 ], causes the retainment of mucins and moist despite the negative effect of gravity.…”

Objectives In this study, we investigated the salivary film thickness and the MUC5B levels at various intra-oral locations in healthy volunteers, with a focus on the palate. Besides, measurements of the palatal surface area were included to explore the possible relationships between the palatal surface area and the palatal salivary film and MUC5B levels. Materials and methods The salivary film thickness was determined using filter strips, which were pressed to the mucosal surfaces of five different intra-oral locations; conductance was then analysed using a Periotron. After elution of the strips, the MUC5B levels at various intra-oral locations were determined using ELISA. The palatal surface area was measured using an intra-oral scanner. The surface area was subsequently calculated using the software. Results The anterior tongue had the thickest salivary film and also the highest levels of MUC5B, while the anterior palate had the thinnest salivary film and lowest MUC5B levels. There was no association between the palatal surface area and the salivary film thickness of the palate. Conclusion The salivary film and MUC5B levels are unequally distributed over the intra-oral regions of the soft tissues. The lack of association between the palatal surface area and the salivary film thickness indicates that a larger surface area is not associated with a relative thinner palatal salivary film. Clinical relevance The results of the current study increase our understanding of saliva distribution in the oral cavity and could be used as reference values for future studies.

“…Recent research reports various uses of palatal rugae such as the association between the pattern of primary rugae with the angle's classes of malocclusion, the applicability of palatal rugae as reference points for cast superimposition in orthodontic patients, the identification of schizophrenic patients, and gender identification (11,(24)(25)(26) . Because their position is usually consistent, palatal rugae are used for identification reasons.…”

Objectives: This study aims to analyze the palatal rugae pattern in the native population of Riyadh province in Saudi Arabia to understand whether the rugae patterns are unique to these ethnic origins and determine whether these palatal rugae patterns can be used as an adjunct aid in biometric human identification. Methods: A cross-sectional descriptive study was conducted among 200 participants within the age group ranging from 18 to 35. Their rugae patterns were analyzed macroscopically (Calcorrugoscopy) to record the length, shape, direction, and unification of the rugae pattern. Findings : It was found that females had a more significant number of palatal rugae (4.83 ± 1.05) as compared with males (4.30 ± 0.93) on the right side, while a reverse trend was seen in terms of the mean length of rugae where males (1.10±0.20) showed longer palatal rugae on the left side than females (0.97±0.17). This difference was statistically significant (p=0.001). A statistically significant difference was found between the mean length of rugae on either side of the palate (p=0.001) with longer rugae on the left side (1.04±.20) than the right side (0.97 ±0.16). Furthermore, a statistically significant difference based on sex was found in straight, curved, convergent, and branched palatal rugae, in the rugae oriented towards the left side of the palate (p=0.001) and in the unification of rugae on the palate's left side (p=0.001) based on sex. Novelty: The natives of Riyadh had a unique characteristic of unification and lesser number of rugae compared to other ethnic groups in Saudi Arabian Population which helps in differentiating them from other ethnicity.

“…The ratio or the pattern of the ruga area remolding was not explained in detail yet but valuable points were found when we did our literature review, and some were listed in this latest review. 3 The lengths, numbers, and positions of the rugae may affected according to specific tooth movement or arch expansion, but individual characteristics did not change. The reference area we used in this study is stable in maximum retraction group with a median of 8.18 mm retraction.…”
