Abstract

To overcome the failure of adhesive bridge due to release of the adhesive bond cement between teeth and metal,preparation modification was performed with a pin hole in the teeth cingulum. This study aimed to determine the effectof thread on a pin hole to shear strength adhesion of adhesive bridge. Forty maxillary incisors were prepared at theirpalatinal surfaces 0.3 mm thick, and were divided into four treatments (threaded hole+threaded pin, threaded holes+non-threaded pin, non-threaded holes+threaded pin, non-threaded holes+non-threaded pin). Casted-plates made fromnickel chromium alloy were cemented to the palatal surface of the tooth with adhesive cement (Panavia TMF 2.0), andthen adhesion shear strength tested. The test and evaluation of the residual cement on the surface were performed inLaboratory Metallurgy, Department of Engineering ITB. Data were analyzed by one-way ANOVA test (p=0.05).Adhesion shear strength of plate with threaded holes+threaded pin has the highest retention. Residual cement onthreaded hole+threaded pin plates similar to threaded hole+non-threaded pin, but more than any other groups. theconclusions were, the adhesion shear strength depends on the design of pin hole. The wider surface of cementremaining on the plates, the greater adhesion shear strength.

Abstract

To overcome the failure of cement adhesive bond between tooth and metal surfaces, a variety of alternative treatmentsis applied to the metal and tooth surfaces. In order to overcome this disadvantage, this study deals with the treatmenton the metal surface in mesh form. This research examined different mesh sizes of 40, 60 and 80 mesh to the metalsurface treatment in shear bond strength of adhesive resin cement. 40 pairs of upper central incisors samples wereprepared in palatal surfaces with a thickness of 0.3 mm and made a pattern of blue wax. The samples were divided intofour groups; three mesh treatment groups (40, 60 and 80) and a control group (no mesh). In the treatment groups, amesh was positioned to the opposing surface of wax pattern to the tooth preparation surface, was casted with nickelchromiumalloy, attached to the palatal surface of the teeth with adhesive resin cement, immersed in artificial salivafor 24 hours at 37°C. Moreover, shear bond strength test and residual resin cement on the metal surface were tested inLaboratory of the Department of Metallurgical Engineering. Data was analyzed using one-way ANOVA (p=0.05).Shear bond strength adherence of mesh plates 60 was found greater than 40, 80 and control group. Stereomicroscopeinspection of adhesive resin cement remaining on mesh 60 was similar than 40, but more than mesh 80 or controlgroup. It was concluded shear bond strength of adhesive resin cement to metal surfaces depends on the size of meshused, and shear bond strength of adhesive resin cement that still intact on the mesh surface.

Abstract

Roselle is a traditional medicinal herb that commonly found in Indonesia. Its ingredients are flavonoids, citric acid,malic acid, lactone, tartaric and antosian. Flavonoids are phenolic compounds that are fungistatic, fungisid andbacteriostatic. Extract of roselle extract has been observed by in vitro inhibit the formation of plaque in oral cavity.This study aimed to examine the effectiveness of pasta of roselle flowers as denture cleansers in inhibiting plaqueformation. Five acrylic full dentures and concentration of 2.5%, 5%, 7.5% and 10% denture cleansers pasta roselleflowers were used. Plaque score was calculated before and after the denture used with an interval of one week. Datawere analyzed using one-way ANOVA and Wilcoxon rank test. Roselle flower toothpaste at a concentration of 2.5%,5%, 7.5% and 10% significantly inhibited plaque formation and there was an effect of different concentrations of pastato the number of plaques (p<0.05). It was concluded that paste of roselle flowers as denture cleaning inhibit theformation of plaque effectively with a minimum concentration was 2.5%, although the most effective concentration ofrosella flower paste as denture cleaning pastes was 10%

Abstract

Lesions caused by traumatic or unbalance occlusion, and overextension denture may occur in the majority ofpatients who use denture. This generally occurs in the use of unfit full dentures (FD) and in a long period of timecausing chronic irritation to mucosal tissues caused by the sharp and overextension of the FD flange. One of themost common tissue reaction caused by using unfit FD is inflammatory fibrous hyperplasia or more commonlyknown as the flabby ridge. This tissue reaction appears as fold of mucosal tissue, single or multiple, growexcessively around the sulcus mucobuccal, on the mucosa area unite gingiva and the cheek mucosa. Movement andgrowth of the tissue continuously causes problems in maintaining retention of FD. This article reports themanagement of denture-induced hyperplasia on maxilla edentulous of a 65-year old woman. Hyperplasia occurredfrom the left premolar to right premolar region of the maxilla. Excision was carried out through a 7 cm length tissueand then made for a conventional FD. As the result, patients are satisfied with the use of the new FD and did notfeel any further disruption to mucosal tissues

Abstract

Cervical margin of fixed denture either jacket crown or bridge, is usually placedsubgingivally for the natural look, however this can sometimes cause gingivalinflammation. Moreover, if the restoration material is acrylic, it sometimes can irritateoral tissue. The aim of this study was to investigate the effect of acrylic, used as fixeddenture material, to gingival tissue reaction. This was an experimental study, using preand post test of 5 acrylic jacket crowns, made to patients in the ProsthodonticDepartment, Dental Hospital of Hasanuddin University. Gingival crevicular fluid (GCF)was collected before preparation, and three weeks after insertion of the jacket crowns,then pro-inflammatory cytokines; TNF-α and IL-1β were examined. The results analyzedby Wilcoxon sign rank test (p<0.05). The results showed the elevation of TNF-α and IL1βconcentration after acrylic jacket crown insertion compare with the concentrationbefore preparation. The conclusion of this study is acrylic restoration material may causegingival inflammation.

Abstract

An alternative treatment for extensive dental caries is using jacket crown. But this restoration could accumulate dentalplaque and can lead to gingivitis. Mouthwash is believed could reduce plaque. Nowadays, most of mouthwash inmarket contains alcohol so that not all individuals can use it. For that reason, we need a free of alcohol mouthwash.The use of medicinal plants from natural materials is increasingly widespread and will be a part of life. One type oftraditional medicinal plants are now widely consumed across the world is roselle flower (Hibiscus sabdariffa L.)because it cointains flavonoid that are fungistatic, fungicid, and bacteriostatic. This studywas aimed to determine theeffective concentration of roselle infusion ingredients to reduce the amount of plaque in acrylic crown. Five peopleusing acrylic crown were asked to rinse using 4 concentration of roselle infusion and distilled water as control for 30seconds, with time interval 1 week for each concentration. Examination of the amount of plaque was performed beforeand after rinsing. The results showed that mouthwash made from roselle infusion is able to reduce the amount ofplaque in acrylic crowns (P<0.05). It was concluded that concentration of 20% roselle mouthwash effectively reducingthe number of plaques at acrylic crown.
