Bacterial Adhesion on Lithium Disilicate Ceramic Surface Exposed to Different Hydrofluoric Solutions

Ceramics (2018)

Daniela Micheline dos Santos Emily Vivianne Freitas da Silva Adaías Oliveira Matos Beatriz Cristiane Zuin Monteiro Rodrigo Antônio de Medeiros

The effect of Fluorine solutions on the surface and bacterial adhesion of lithium disilicate is a concern. The aim was to evaluate the surface roughness and the adhesion of Streptococcus sanguinis on lithium disilicate ceramic, under the influence of different solutions containing Fluorine. Forty lithium disilicate (IPS e.max Press Impulse) discs (2.5 × 5 mm) was divided into 4 groups (n = 10): artificial saliva (Group AS), 0.2% sodium fluoride (Group NaF), 1.23% acidulated phosphate fluoride gel (Group APF), and mouthwash (Group MW). Roughness analyses were performed before and after the immersion. The surface aspect was evaluated by scanning electron microscopy (SEM) and the adhesion of Streptococcus sanguinis were evaluated after immersion in the solutions. The data obtained were submitted to the analysis of variance (ANOVA) and the Tukey test (α = 0.05). The Group APF presented a bigger roughness (3.263), statistically different to the other solutions. The bacterial adhesion in the Group APF (5.85) presented statistical difference to the other solutions. The SEM micrographs showed a rougher surface in Group APF. The 1.23% APF gel promoted major surface roughness and bacterial adhesion and could be inadequate for the use of patients with lithium disilicate ceramic restorations. Clinical significance: The Fluorine solution can affect the lithium disilicate ceramics, generating a rough and non-esthetic surface. This altered surface could be susceptible to bacterial adhesion, being directly related with periodontal health, the longevity of the restoration and the success of the rehabilitation.

Comparison of different methods for obtaining centric relation: a systematic review.

General dentistry (2021)

Clóvis Lamartine de Moraes Melo Neto Emily Vivianne Freitas da Silva Isabela Caroline de Sousa Ervolino Daniela Micheline dos Santos André Pinheiro de Magalhães Bertoz

The objective of this study was to compare techniques of different methods of obtaining centric to verify which technique generates the greatest of the centric relation. The PubMed/MEDLINE, Cochrane Library, SciELO, Scopus, and Web of Science databases were searched for articles published up to May 15, 2018. The search terms were combinations of dental centric relation with each of the following terms (individually): reproducibility of findings; jaw record; point; arch; manipulation; swallowing; and jig. The inclusion criteria included clinical studies in English that had to compare at least 2 techniques representing different methods for obtaining centric (based on the of the centric relation) in individuals without temporomandibular dysfunction; and studies performed in individuals with complete or nearly complete dentition or complete edentulism. Methods (techniques) included in this study were guided methods (chin point guidance and bimanual manipulation); graphic methods (intraoral and extraoral gothic arch tracing); and physiologic methods (swallowing and tongue retrusion along the palate). A total of 1638 articles were identified. After the inclusion and exclusion criteria were applied, 7 articles were included in this review. None of the reviewed studies evaluated edentulous individuals. Two articles compared physiologic methods with guided methods; one concluded that the swallowing technique generates greater variability than guided methods, and the other concluded that there was no difference between the swallowing technique and chin point guidance. Of 5 articles comparing intraoral gothic arch tracing with guided methods, 2 showed similar results between different methods, 2 showed superior results for gothic arch tracing, and 1 showed superior results for the guided methods. Based on the guided methods and swallowing technique, it is not possible to conclude which technique can generate the greatest of the centric relation. It is possible to suggest that in most cases intraoral gothic arch tracing is superior or equivalent when compared to guided methods.

Extended-pour and conventional alginates: effect of storage time on dimensional accuracy and maintenance of details

Dental Press Journal of Orthodontics (2021)

Sandro Basso Bitencourt Isabela Araguê Catanoze Emily Vivianne Freitas da Silva Karina Helga Leal Túrcio Daniela Micheline dos Santos

ABSTRACT Objective: This study aimed to evaluate the dimensional stability and maintenance of details of conventional and high stability alginates up to 5-day storage. Methods: Two types of alginates were selected (n=10) for this study, conventional (Hydrogum) and high stability alginates (Hydrogum 5), which were produced with the aid of a cylindrical metal block and a ring-shaped metal mold (Specifications 18, 19, and 25, ANSI/ADA). Ten images were obtained from the molds for the dimensional stability test, which were taken immediately after their production and at each different storage periods (15 min, 24 h, 48 h, 72 h, 96 h, and 120 h) by a digital camera. The specimens were kept hermetically sealed in plastic bags (23°C) and then used to obtain 140 (n=70) dental stone models, used in the detail reproduction test, in which the angular accuracy of three grooves (20 µm, 50 µm, and 75 µm) was observed at each period. The details reproduction accuracy was classified using a predetermined score classification. Measurements of dimensional changes were made in the Corel DRAW X6 program. The data were submitted to the Student’s t-test (α?#8197;= 0.05). Results: A statistically significant difference concerning the size of the matrix was observed after 24h for both alginates, and a statistically significant negative linear dimensional change (contraction) was verified after 24 h of storage (1.52% for the high stability alginate, and 1.32% for the conventional alginate). The high stability alginate kept the full details for 72 hours, while the conventional alginate, for 24 h. Both alginates reproduced the 75 µm groove at all storage periods. Conclusion: Impressions made with both alginates presented satisfactory clinical results when the alginates were immediately poured.

Effect of Rehabilitation with a New Ocular Prosthesis on Electromyography of the Occipitofrontalis, Temporal, Masseter, and Sternocleidomastoid

European Journal of Dentistry (2021)

Fernanda Pereira de Caxias Karen Letícia Sa Teles Daniela Micheline dos Santos Clóvis Lamartine de Moraes Melo Neto Emily Vivianne Freitas da Silva

The aim of this study was to verify during facial expressions ("happy," "sad," "fearful," "angry," "surprised," and "disgusted") if: (1) there would be difference in the electromyography (EMG) of the occipitofrontalis, temporal, masseter, and sternocleidomastoid muscles on the normal side (NS) compared with the affected side (AS) (without the use of an ocular prosthesis) in individuals with unilateral absence of the eyeball, and (2) the rehabilitation with a new ocular prosthesis would affect the EMG of the muscles studied on the AS in these individuals. Thirteen individuals, without temporomandibular disorder, with good health, with unilateral absence of the eyeball (the eye must have been removed by evisceration or enucleation), and users or nonusers of an ocular prosthesis were included. EMG of the occipitofrontalis, temporal, masseter, and sternocleidomastoid muscles was performed during rest and facial expressions ("happy," "sad," "fearful," "angry," "surprised," and "disgusted") before (T0) and 90 days after (T1) rehabilitation with a new ocular prosthesis. The analyses were performed in T0 on NS and AS (without the use of an ocular prosthesis), and in T1 on AS with the new ocular prosthesis. All data were submitted to the Student's t-test with p < 0.05. There was no statistically significant difference comparing the AS with the NS in T0 for all muscles studied, during all facial expressions evaluated (p > 0.05). There was no statistically significant difference comparing the AS in T0 with itself in T1 for all muscles studied, during all facial expressions evaluated (p > 0.05). Eye loss did not affect the EMG of studied muscles when comparing NS with AS (without the use of an ocular prosthesis). The rehabilitation with ocular prosthesis was not capable of changing the EMG on AS.

Effect of acidic beverages on surface roughness and color stability of artificial teeth and acrylic resin

The Journal of Advanced Prosthodontics (2020)

Sandro Basso Bitencourt Isabela Araguê Catanoze Emily Vivianne Freitas da Silva Paulo Henrique dos Santos Daniela Micheline dos Santos

The aim was to evaluate the effect of four acidic beverages on the roughness (Ra) and color change (ΔEab) of two brands of artificial teeth and a heat-polymerized acrylic resin (HPAR) for use in a prosthetic base.All materials were divided into 5 groups, according to the used acidic beverage (artificial saliva - control, red wine, orange juice, coke-based, and lemon juice-based soft drink). The immersion process was divided into two stages: T1 - immersion in the acidic solutions for 10 minutes for 14 days; T2 - after T1, the samples were immersed in grape juice for 14 days. The Ra of the samples was evaluated in a rugosimeter and the ΔEab in a spectrophotometer, before and after the immersions. The analysis of variance of one (ΔEab) and two factors (Ra) and Tukey were performed (α=.05).There was a statistical difference for roughness after immersion (T1) for Trilux and Tritone teeth, regardless of the acid solution. For Trilux teeth, all acid solutions increased Ra (P<.05). For Tritone teeth, only the coke-based soft drink did not statistically change Ra. Grape juice (T2) altered Ra only of artificial teeth (P<.05). The color was changed for all materials, after T1 and T2.In general, the acidic solutions changed the Ra and ΔEab of HPAR and artificial teeth after T1. The grape juice altered the roughness only of the artificial teeth, promoting a clinically acceptable color change in the materials.

Simplified prosthetic rehabilitation of a patient with partial finger amputation after a firearm injury

Prosthetics and Orthotics International (2022)

Paulo Augusto Penitente Emily Vivianne Freitas da Silva Lucas Fernando Tabata Marcelo Coelho Goiato Rodrigo Antônio de Medeiros

This study reports a clinical case of rehabilitation of a patient who had her left little finger amputated at the mesial phalanx because of a gunshot wound. The finger prosthesis was custom- made using a silicone.This study presents a clinical case of a female patient who had her left little finger amputated at the mesial phalanx because of a gunshot wound in 2016. The patient was attended at a reference center in maxillofacial rehabilitation in the city of Brasilia, Distrito Federal, Brazil, for the manufacture of a finger prosthesis. After molding, a finger waxing was obtained using the right little finger as a template. The waxing was later adjusted on the plaster model of the affected stump. The prosthesis was manufactured with silicone and intrinsically stained with a makeup powder. A water-based adhesive and a ring were used to generate a slight compression so that the prosthesis was retained on the stump.The rehabilitation showed satisfactory levels of stability, retention, and aesthetics, and it was usable and clinically acceptable, as observed in a follow-up appointment in February 2020.The complete or partial reestablishment of functions performed by important structures, such as the fingers, is essential to increase the quality of life of individuals, improving their performance of daily activities. In addition, reporting on this public health problem allows scientific advancement in the area.
