Methods for evaluation of masticatory efficiency in conventional complete denture wearers: a systematized review

The objective of this study was to present a systematized review of different methods used to evaluate the masticatory efficiency in conventional complete denture wearers. A survey was conducted in the databases PubMed, Scopus, and Cochrane, seeking scientific articles according to the previously selected terms: "Masticatory performance", "Masticatory efficiency" and "Chewing ability complete denture". Moreover, complementary studies have been carried out with library manual search/databases, which included studies related to different ways to assess masticatory efficiency, specifically as it related to conventional complete denture wearers. Forty three papers were selected to be used in the present review. Despite the wide variety of methodologies in the literature, the sieves method is currently considered the gold standard method to evaluation of conventional complete denture wearers masticatory efficiency, since it is the simplest, does not depend on specific devices (beyond the set of sieves), allows for a rational assessment, and it has been widely reproduced in various types of oral rehabilitation. More, the almond, as natural test food, and the optocal (made from the molding material Optosil), as artificial test food, are the most constantly employed test foods to evaluate masticatory efficiency.

Hipertonicidade muscular e confecção de próteses totais pela técnica da zona neutra: relato de caso clínico

Introduction: the oral rehabilitation in edentulous patients using removable complete dentures is a classic treatment, easily accessible, and presenting satisfactory results. However, to succeed in this type of treatment, stability is an extremely important factor. The neutral zone technique for the production of complete dentures determines the oral cavity space for the positioning of teeth and denture base that provide a neutralization of the forces delivered by lips, cheeks, and tongue, providing better stability and retention of prostheses, which is indicated in cases with history of difficulties in adapting the conventional mandibular denture. Objective and case report: this paper aimed to describe a clinical case report of the oral rehabilitation of a patient with paraprosthetic muscles hypertonicity through removable complete dentures produced by the neutral zone technique, using condensation silicone. Final considerations: the use of condensation silicone for the development of the neutral zone technique showed to be a good alternative for the development of this clinical case, providing satisfactory stability and retention of the complete mandibular denture.

Resina composta indireta como alternativa funcional e estética em reabilitações protéticas

Due to mechanical and aesthetic improvement properties, continuous fiber-reinforced composites have been developed to replace the metal framework in fixed partial dentures becoming an interesting alternative to conventional treatments. A male patient, 57 years old, attended at Fixed Partial Denture Clinic of Araraquara Dental School - UNESP, complaining about upper right first molar absence. After clinical examination, it was observed: upper right second molar with amalgam restoration and periodontal bone reduction and upper right second premolar unsatisfactory treated. Following the clinical conditions and the patient expectations, it was decided to use a fiber-reinforced composite resin to make a three-element fixed bridge. The patient showed full satisfaction with the aesthetic and functional results. The case has been followed up for 60 months.

Estudo prospectivo sobre a utilização de próteses totais implantossuportadas em pacientes edêntulos

The objective of this study was to evaluate the impact of replacing conventional mandibular complete dentures by complete fixed dentures on the oral health-related quality of life and kinesiographic parameters of maxillary edentulous patients. Material and Methods: edentulous patients (n = 16) received one set of new complete dentures and after the intraoral adjustments and adaptation period (30 days), the Brazilian version of Oral Health Impact Profile for assessing edentulous subjects (Ohip-Edent) was used to evaluate the oral health-related quality of life (OHQOL) of the participants. Additionally, the kinesiograph instrument K6-I (Myotronics Research Inc., Seattle, WA) was used to record opening and closure range of movement, mandibular movement, and the pattern of maxillary complete denture movement on chewing. Afterwards, the patients had their mandibular complete dentures replaced by a complete fixed denture and the same evaluation protocol was performed after 3 and 6 months. Ohip-Edent responses were analyzed using Wilcoxon's test for repeated measures (α = .05) and Kinesiographic data using the Student´s t test (α = .05). Results: The Ohip-Edent showed an improvement of general oral health-related quality of life after 3 and 6 months of the treatment with complete fixed dentures. Kinesiographic recordings revealed a significant increase on maximum mandibular movements of vertical opening and no differences for the movement of the maxillary complete denture on chewing after treatment with complete fixed dentures was observed. Conclusion: the installation of complete fixed dentures improved the OHQOL and changed mandibular movements, with increases in vertical amplitude of maximal opening.

Masticatory performance of complete denture wearers after using two adhesives: a crossover randomized clinical trial

Statement of problem Masticatory performance analysis of conventional complete denture wearers who use denture adhesives is scarce in the dental literature. Purpose The purpose of this study was to assess the effect of the use of 2 denture adhesives on the masticatory performance of conventional complete denture wearers by means of a crossover study. Material and methods Forty individuals who were edentulous received new maxillary and mandibular complete dentures, and, after an adaptation period, were submitted to masticatory performance analysis without denture adhesive (control). The participants were randomly divided and assigned to 2 protocols: protocol 1, denture adhesive 1 (Ultra Corega cream tasteless) use during the first 15 days, followed by no use of denture adhesive over the next 15 days (washout), and then use of denture adhesive 2 (Ultra Corega powder tasteless) for 15 days; protocol 2, denture adhesive 2 (Ultra Corega powder tasteless) use during the first 15 days, followed by no use of denture adhesive during the next 15 days (washout), and then use of denture adhesive 1 (Ultra Corega cream tasteless) for 15 days. The masticatory performance was assessed immediately after the use of denture adhesive by means of the sieve method, in which participants were instructed to deliberately chew 5 almonds for 20 chewing strokes. Masticatory performance was calculated by the weight of comminuted material that passed through the sieves. Data were analyzed by a 1-way ANOVA for paired samples and the multiple comparison of means by using the Bonferroni test (α=.05). Results A significant increase in masticatory performance was noted after using the Ultra Corega cream (mean, 32.6%) and Ultra Corega powder (mean, 31.2%) when compared with the control group (mean, 19.8%) (P<.001). No significant difference was found between the 2 denture adhesives evaluated. Conclusion The use of denture adhesive improved the masticatory performance of conventional complete denture wearers. No difference was found in masticatory performance with the use of cream or powder denture adhesive.

Human identification by means of conventional and digital Cheiloscopy: a study of the literature

One of the areas of human identification is Cheiloscopy, the name given to the study of the lips, their characteristics (such as thickness, position of the grooves and grooves) and the record of the impressions left by them. There are variations in the layout of the lines and fissures of the lips, which are unique to each individual, permanent and unchanging. The lip print rarely changes, enduring minor traumas such as inflammation or sores. In criminal investigations, lip prints, visible through the presence of lipstick, can be found on glasses, napkins, clothes, cigarettes, indicating a relationship between the subject and the scene of the crime. Latent impressions may be revealed employing specific chemicals such as powder of silver and aluminum nitrate. Although it is not a very common method, Cheiloscopy may become very useful in forensics due to the extensive amount of valuable information that it brings. The objective of this study was to review the literature on the use of Cheiloscopy in human identification, using traditional and digital methods. It was found that the literature is still in need of studies in this area. The advent of new digital technologies can facilitate the implementation of technical expertise, generating speed and objectivity. New research studies are necessary, especially in the development of digital methods. The application of Cheiloscopy can greatlyhelp with Law, in the identification of living suspects and dead individuals. In the end the benefit will fall to society as a whole.

The effect of conventional mechanical periodontal treatment on red complex microorganisms and clinical parameters in Down syndrome periodontitis patients: a pilot study

Periodontal disease (PD) is induced by a complex microbiota, such as Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola (together called the red complex), which triggers intense inflammatory reaction. Down syndrome (DS) individuals demonstrate a high prevalence of PD compared with those who are otherwise chromosomally normal (euploids). This pilot study aimed to evaluate the effect of non-surgical periodontal treatment in DS chronic periodontitis patients on clinical and microbiological parameters. Patients with chronic periodontitis, 23 DS and 12 euploids (control group), were submitted to non-surgical mechanical periodontal treatment, followed by maintenance for 45 days. Clinical parameters after periodontal treatment were similar in diseased and healthy sites, independent of the genetic background. Diseased sites of DS and control patients harbored similar levels of P. gingivalis and T. forsythia at baseline, but significantly higher levels of T. denticola were found in DS patients. Increased levels of P. gingivalis at healthy sites were found in DS individuals. Non-surgical periodontal therapy decreased the levels of red complex microorganisms and improved the tested clinical parameters of diseased sites in both groups. However, the levels of red complex bacteria were higher in diseased sites of DS patients after the periodontal treatment. We conclude in this pilot study that, although the mechanical periodontal treatment seemed to be effective in DS subjects over a short-term period, the red complex bacteria levels did not decrease significantly in diseased sites, as occurred in controls. Therefore, for DS patients, it seems that the conventional non-surgical periodontal therapy should be improved by utilizing adjuvants to reduce the presence of periodontopathogens.

Intraoral fluoride levels after use of conventional and high-fluoride dentifrices

This study aimed to evaluate saliva and plaque as indicators of intraoral fluoride (F) levels after the use of conventional and high-fluoride dentifrices.Subjects were randomly assigned to brush their teeth with conventional (1000 ppm F), high-fluoride (5000 ppm F), and placebo dentifrices (fluoride free) for 10 days, following a double-blind, crossover protocol. Saliva and plaque samples were collected on the morning of the 5(th) and 10th days, respectively at 1 and 12 h after brushing, and analyzed with an ion-selective electrode after HMDS-facilitated diffusion. Data were analyzed by two-way repeated measures ANOVA, Tukey's test and Spearman's correlation coefficient (p < 0.05).Plaque and salivary F levels were significantly increased after the use of conventional and high-fluoride dentifrices when compared to values obtained for placebo, except plaque 12 h after the use of conventional dentifrice. A positive and significant correlation was found between fluoride concentrations in plaque and saliva for both times of sample collection.Both indicators assessed were able to detect significant differences among treatments and between times after brushing. The use of a high-fluoride dentifrice is able to significantly increase intraoral fluoride levels throughout the day, being therefore a useful therapy for patients at high caries risk.A dentifrice with high fluoride concentration could be regarded as a useful therapy of F delivery for high caries-risk patients, since intraoral F levels were sustained throughout most of the day after using this formulation.
