Academic literature on the topic 'Incisive papilla'

Introduction: Arranging artificial teeth has always been a challenging work since edentulous alveolar ridges are in a constant verge of physiological resorptive changes. Incisive papilla is a reliable biometric guide which can be used as a reference for arrangement of anterior teeth, since it is a stable intraoral anatomical landmark unless surgically modified. Objective: This study was conducted to determine the mean distance between the most prominent labial surface of maxillary central incisors to the posterior limit of incisive papilla in various arch forms. Materials and Methods: The study was carried out among 170 undergraduate students of BPKIHS, after obtaining ethical clearance from Institutional Review Committee, BPKIHS. Maxillary impressions were made with alginate impression materials and casts were poured with dental stone. Distance from the posterior limit of incisive papilla to maximum convexity of central incisor (Papillo-Incisal Distance, PID) was measured with a Digital Vernier caliper with a precision of 0.01mm. The arch forms were analyzed and classified into ovoid, tapering and squarish arch, subjectively based on morphological parameters. The intra-examiner reliability of the measurement was tested in 17 casts calculating Cronbach’s Alpha. Pearson Chi-square test was applied to explore the relation of the arch forms with age and gender. One-way ANOVA was used to check the association between the mean PID between with different arch forms.(p value = 0.05) Results: The mean distance from the labial surface of maxillary central incisors to the posterior limit of incisive papilla was 11.58±1.32 mm. The mean papillo-incisal distance varied with respect to different arch forms which was statistically significant (P<0.05). The mean PID of oval, squarish and tapering arch forms were 11.86 mm, 10.82 mm and 11.93 mm respectively. Conclusion: Incisive papilla is a valuable starting point in the preliminary location of maxillary incisors during fabrication of dentures. The suggested mean PID for arranging central incisors is 11.58 mm.

ABSTRACT Aim The study was carried to find a relationship between the postextraction stable landmark, the incisive papilla, and the most labial position of the maxillary central incisor teeth, which occurred in Nepalese population. Materials and methods Casts of the subjects selected by nonprobability random sampling meeting the inclusion criteria were obtained. Each casts were standardized with respect to the occlusal plane and a photographic technique was used to measure the distance from the tangent of the labial surface of the central incisors to the posterior border of the incisive papilla. The measurements were made using Adobe Photoshop and results were analyzed by using appropriate statistical methods. Most appropriate software (SPSS) for the purpose was used to generate all desired values. Results The data obtained suggested that the distance from the labial surface of maxillary central incisors to the posterior border of the incisive papilla ranged from 9 to 15.9 mm with a mean of 11.59 mm (SD 1.3). Various other results were also found after evaluation of the arch forms in relation to sex and race. Conclusion Within the limitations of the study, these results suggested that there is a relationship between the maxillary central incisors and the incisive papilla aiding in the anteroposterior positioning of the anterior tooth. The clinical relevance of the study lies in application of the incisive papilla as a starting point in the preliminary location of maxillary incisors and canines during construction of the denture in absence of preextraction records.

Immunohistochemistry for several neurochemical substances was performed on the human incisive papilla and other oral structures. Sodium channel alpha subunit 7 (SCN7A) protein-immunoreactive (IR) Schwann cells and protein gene product 9.5 (PGP 9.5)-IR nerve fibers made nerve plexuses beneath the epithelium of the palate, including the incisive papilla, tongue, and lip. SCN7A immunoreactivity could also be detected in lamellated and nonlamellated capsules of corpuscle endings. Lamellated SCN7A-IR corpuscle endings were mostly restricted to the mucous and cutaneous lips. These endings had thick and spiral-shaped PGP 9.5-IR axons without ramification. Nonlamellated SCN7A-IR corpuscle endings were most numerous in the incisive papilla among the oral regions. On the basis of axonal morphology, the nonlamellated endings were divided into simple and complex types. PGP 9.5-IR terminal axons in the simple type ran straight or meandered with slight ramification, whereas those in the complex type were densely entangled with abundant ramification. Substance P (SP)-, calcitonin gene-related peptide (CGRP)-, and transient receptor potential cation channel subfamily V member 2 (TRPV2)-IR varicose fibers were rarely seen beneath the epithelium of oral structures. The present study indicates that the human incisive papilla has many low-threshold mechanoreceptors with nonlamellated capsules. SP-, CGRP-, and TRPV2-containing nociceptors may be infrequent in the incisive papilla and other oral regions.

Abstract Aim The validity of the relationship between the maxillary anterior teeth and the incisive papilla and the pertinence of this relationship to Jordanians was examined. Methods and Materials A computerized digital caliper (CDC) tool was developed and used in the measurements which were made on scanned images of dental casts of 298 Jordanians. The distances from a tangent to the labial surface of the central incisors to the midpoint and the posterior border of the incisive papilla were measured. The tool was also used in marking the exact point on the incisive papilla of the intersection with the line that connected the tips of the maxillary canines. The data sets were analyzed statistically and comparisons among various sets were drawn at a 95% confidence level. Results Gender had no significant effect on the relationship of the incisive papilla to the maxillary anterior teeth, whereas this relationship was significantly influenced by the incisal classifications of the examined subjects. Conclusion Differences between the Jordanian scores and the Caucasian norms were insignificant. Clinical Significance Therefore, the guidelines recommended for Caucasians could be used as starting points in the preliminary location of maxillary incisors and canine teeth during construction of dentures for Jordanians.

A case of unusual hamartoma in a six-year-old otherwise healthy Brazilian girl is reported, with emphasis on histological and immunohistochemical features. A mass observed in the incisive papilla was detected whose appearance was similar to congenital epulis or fibroma. Histological findings showed interlacing fascicles of large spindle cells resembling smooth muscle cells. Immunohistochemical staining for desmin and for smooth-muscle actin was positive. The histological diagnosis was leiomyomatous hamartoma, based on clinical and microscopic observations.

ABSTRACTObjectives: The aim of the present study was to determine the vertical distance between maxillary central incisors and incisive papilla.Methods: The vertical distance between incisal edges of maxillary central incisors and the centre of the incisive papilla was measured by a digital caliper on the stone casts that were obtained from dentate subjects.Results: The mean vertical distance between maxillary central incisors and incisive papilla on the stone casts was 6.70±0.81 mm. The vertical distance range was 5.51 mm to 8.89 mm.Conclusions: The clinical relevance of this study lies in application to complete denture construction. The dentist and laboratory technician can be use the results of this study as a guideline in fabrication of maxillary occlusal rims and in determination of the position of the occlusal plane with the reference of other anatomical landmarks together. However, the wax rim should be modified intraorally to incorporate individual characteristics and the anterior tooth should be arranged on modified wax rim. (Eur J Dent 2008;2:161-166)

Introduction: Teeth’s arrangement in complete dentures is a complex process that should ensure functional an aesthetics competences to the patient. The placement of the superior central incisor has great importance. Therefore it is imperative to use a stable and immobile anatomic landmark, as the incisive papilla, that allows a correct prosthetic teeth’s arrangement. Objectives: Analyse the anatomic relationship between incisive papilla and superior central incisor, superior canines, arch form and facial midline in University Catholics of Portugal’s patients rehabilitated with complete dentures. Determine if there are significate differences between these relationships and the dentulous/edentulous state, gender and number of years of complete denture use. Material and methods: 35 patients with superior complete dentures and 35 patients with natural dentition from university clinic were observed and divided in study group and control group, respectively. Personal data and results from measurements of horizontal and vertical distances between superior central incisor and incisive papilla, vertical distance from canine to incisive papilla, intercanine distance, relationship between intercanine line and incisive papilla, arch form and coincidence of incisive papilla with facial midline were recorded. Results: There was a relationship between horizontal and vertical distances between incisive papilla and superior central incisor and canine, and between intecanine line distance and the two groups. In dentate group there was a relation between genders and intercanine distance. Vertical distance from superior central incisor and intercanine distance were influenced by arch shape. There is a strong relationship between group and incisive papilla shape. Conclusion: We can conclude that’s important to standardize measure points and methods and reference plane used so that way this measurements could be used as guidelines to teeth’s arrangement in complete dentures.

Cellulitis is an acute, spreading infection of the deep dermis and subcutaneous fat characterized by erythema, warmth, swelling, and pain. Erysipelas is an infection of the more superficial cutaneous lymphatics and skin, including the epidermis as well as the upper reticular and papillary dermal layers. It is commonly located on the lower extremities, face, and ears. Cutaneous abscesses are purulent collections that occupy the dermis and deeper soft tissues. Effective treatment of cellulitis and erysipelas includes antibiotics and elevation of the affected area to assist in lymphatic drainage. Methicillin-resistant Staphylococcus aureus (MRSA) infection should be considered in all cellulitis or erysipelas patients who have failed initial therapy, have a history of or risk factors for MRSA, or have severe infection or systemic toxicity. The first-line treatment for a cutaneous abscess is incision and drainage (I&D); no data demonstrates the utility of antibiotic therapy in conjunction with I&D.
