Abstract

Mechanical pulp exposure by a rotary cutting instrument or a hand-cutting instrument often happens in deep caries. Application of protective dressing can protect the pulp from additional injury by facilitating healing and repair. Pulp capping has been suggested as one treatment of choice after pulp exposure to maintain pulp vitality. TGF-β1 is growth factor that has important rule in wound healing. The application of Ca(OH)2 and exogenous TGF-β1 as direct pulp capping tr4eatment must be experimented in-vivo to see the vacuolization and necrosis in 7, 14, and 21 days after application. This research was done in vivo experiment from orthodontic patients indicated for premolar extraction, between ages 10–15 years. A class V cavity preparation was created in the buccal aspect 1 mm above gingival margin until pulp exposure. Cavity was irrigated slowly with saline solution and dried with a sterile small cotton pellet. Group 1 calcium hydroxide was applied as manufacture procedure. Group 2, the sterile absorbable collagen membrane used, as inert carrier of TGF-β1 was soaked with 5 ml. All groups were covered by a Teflon pledge to separate pulp capping agent from glass ionomer cement restoration. Teeth extracted in 7, 14 and 21 days after treatment. All samples were hystopathologically examined. There were significant difference of TGF-β1 (p < 0.05) in the vacuolization day 14th and 21th compared with 7th. there were not significant difference in necrosis for all variables. Vacuolization and necrosis decreased in the application of TGF-β1.

Abstract

The aim of mandible reconstruction using reconstruction plate after resection is to restore aesthetic and function for muscles attachment and allow mandible movement during normal function and free from joint problem. Temporomandibular joint (TMJ) is an area of concern during mandible reconstruction using reconstruction plate as misalignment on placing of the reconstruction plate may cause the joint place in distortion to the glenoid fossa. Loss large part of mandible bone structure may lead problems during mandible reconstruction procedure because the surgeon may lose in orientation during forming the reconstruction plate into a horseshoe-shaped form of the mandible as well as during plate placement. The plate can only be well adapted when the position of two distal ends of the resected mandible bone are in a stable position. Simple ascending ramus fixator (CARF) to fix the ascending ramus in its stable original position to allow easy mandible reconstruction was created. Those CARF were designed in two types which have one and two fixator stems used to stabilize one or both sites of the ascending rami and showed its effectiveness.

Abstract

Calcium hydroxide had been used as the intra-canal dressing in endodontic treatment due to its high alkaline and antimicrobial capacity. It can also dissolve the necrotic tissue, prevent dental root resorbtion and regenerate a new hard tissue. The aim of this study was to determine the concentration of calcium hydroxide which had the highest antimicrobial effect on Streptococcus viridans. Samples were divided into 5 groups; each group consisted of 8 samples with different concentration of calcium hydroxide. Group I: 50%, group II: 55, Group III: 60%, Group IV: 65%, Group V: 70%. The antimicrobial testing was performed using diffusion method against Streptococcus viridans. The result of susceptibility test was showed by the inhibition zone diameter which measured with caliper (in millimeter). We analyzed the data using One-Way ANOVA test with significant difference 0.05 and subsequently LSD test. The study showed that calcium hydroxide with concentration 60% has the highest antimicrobial effect.

Abstract

The most visible repair response to pulp injury is the deposition of a tertiary dentin matrix over the dentinal tubules of the primary or secondary dentin. Tertiary dentin is distinguished as reactionary and reparative dentin, depending on the severity of the initiating response and the conditions under which the newly deposited dentin matrix was elaborated. Transforming growth factor beta (TGF-b) superfamily is a large group of growth factors that serve important roles in regulating cell growth, differentiation, and function. Members of this superfamily have been implicated in the repair process of the dental tissue after injury. Although numerous studies have proved that those bioactive molecules carry out an important role in the formation of tertiary dentin, comprehensive report regarding that phenomenon is not yet available. This review article aimed to summarize the role of TGF-b on tertiary dentinogenesis during the progression of a carious lesion.

Abstract

There is a possible relationship between dental plaque and children allergic diseases. According to literatures, gingivitis suffered mostly by allergic children than control. Case reports also revealed that dental plaque control therapy was able to reduce, even eliminate rhinosinusitis and asthmatic symptoms without additional medications. However, the exact method for confirming the gingivitis-related allergy is still uncertain. Allergic diseases have multifactorial etiologies and dental plaque had been proposed as a new trigger of allergic symptoms. Nevertheless, since not every child with gingivitis suffered from allergy or vice versa, this uncertain phenomenon may lead to patients or other clinician disbelief. The objective of the present study was to propose a new method, which involving the Gingival immunologic defense index (GIDI) to evaluate the susceptibility to allergic diseases. GIDI is an index that had been developed earlier for evaluating gingival immunologic defense with respect to immunoglobulin A (IgA) levels. This index based on the simple count of the inflamed gingival surfaces of a child plus the measurement of salivary IgA content. It provides clinicians with important information about the immunologic defense potential of each subject. Interestingly, most allergic children also had inherited IgA deficiency, thus this concept is likely. Based on literatures, GIDI could be a potential index for evaluating the risk of allergic diseases through gingival health assessment. However, prior investigation to the value of Indonesian GIDI index which related to allergy should be conducted.

Abstract

Ideally in orthodontic tooth movement, alveolar bone will follow its movement, therefore, the ratio between bone remodeling and tooth movement is 1:1. The problem whether the ratio is valid for all kinds of tooth movement such as: tipping, torquing, or bodily, or it could be applied in tooth movement of all directions such as facially, lingually or sagitally. Various studies also showed many different ideas. Some studies state that root dehiscence and fenestration are frequently found in final orthodontic treatment and some other state that bone remodeling can compensate tooth movement. The purpose of this study was to know the changes of alveolar bone morphology caused by anterior tooth movement. The conclusion is remodeling compensation is not matched with the extension of tooth movement, thus there are many cases of root dehiscence and fenestration after orthodontic treatment.

Abstract

Toll-like receptors (TLRs) have recently emerged as key receptors of the innate immune system. They recognize specific pathogenassociated molecular patterns initiating a host defence response. The oral mucosa epithelium encounters potential pathogens like bacteria and viruses in inspired air, and the discovery of TLRs on epithelial cells suggest that the epithelium has a role in the mucosal immune system. The aim of this study was to discover Recurrent Apthous Stomatitis (RAS) using etiopathogenetic molecular approach by observing the TLRs. Immunohistochemistry using monoclonal antibodies anti-TLR-2, TLR-3, TLR-4, TLR-5, TLR-7 and TLR-9 were used in this study. These antibodies are specific toward TLR on the surface of epithelial cells membrane and macrophages in patients with major and minor RAS. TLR was expressed on the surface of epithelial cells membrane of oral mucosa and macrophages in both major and minor RAS patients. TLRs was not expressed specifically in non-RAS patients. The results above showed indication, that functional TLRs expression by epithelial cells in oral mucosa had remarkable implication on natural immune response and disease pathogenesis. The expression of TLR was found in the oral mucous membrane on epithelial cells surface and macrophages patients with RAS.

Abstract

Denture stomatitis is an inflammation of oral cavity due to removable denture wearing. Prevention of denture stomatitis can be effectively done by using mouth rinsing. Currently, Indonesian government is actively promoting traditional herbal medicine as an alternative medicine such as Psidium guajava Linn leaf which has an anti bacterial and anti fungal ability. The purpose of this study was to know the effective concentration and soaking duration to reduce Candida albicans without lowering transversal strength of acrylic resin. This experimental laboratory study was using heat cured acrylic resin plate without surface polishing. The concentration of Psidium guajava Linn leaf extract used in this study were 32%, 34%, 36%, and 38% respectively with 15 minutes, 30 minutes, 1 hour and 8 hours soaking duration. The transversal strength was measured in the same concentration with 2 days, 10 days and 60 days soaking duration. Sterile aquadest was used as control. Two direction ANOVA and LSD test were used in data analysis. The result showed significant difference in the number of Candida albicans colony among concentrations and soaking durations. Significant difference was also found in transversal strength among concentrations and soaking durations. It is concluded that the extract of Psidium guajava Linn leaf in 38% concentration with 8 hours soaking duration will lower the Candida albicans colony, whereas 38% concentration with 60 days soaking duration will lower the transversal strength but it is still above the standard value.

Abstract

The purpose of this study was to investigate the three dimensional changes in the fitting surface and artificial teeth of maxillary complete dentures which were fabricated using two different polymerizing processes: heat polymerization (HP) and microwave polymerization (MP), after immersion in water for seven days. The amount of distortion in the molar region of the alveolar ridge was significantly different between HP and MP. However, the overall distortion of the dentures polymerized using both methods was similar. The distortion due to immersion in water for seven days compensated for the polymerization distortion, but the amount of distortion was very slight.

Abstract

Dental amalgam is an alloy composed of mixture of approximately equal parts of elemental liquid mercury and an alloy powder. The popularity of amalgam arises from excellent long term performance, ease of use and low cost. Despite the popularity of dental amalgam as restorative material, there have been concerns regarding the potential adverse health and environmental effects arising from exposure to mercury in amalgam. They have long been believed to be of little significance as contributors to the overall body burden of mercury, because the elemental form of mercury is rapidly consumed in the setting reaction of the restoration. In 1997, 80% of dentist in Indonesia still using amalgam as an alternative material, and 60% of them treat the rest of unused amalgam carelessly. In recent years, the possible environmental and health impact caused by certain routines in dental practice has attracted attention among regulators. As part of point source reduction strategies, the discharge of mercury/amalgam-contaminated wastes has been regulated in a number of countries, even though it has been documented that by adopting appropriate mercury hygiene measures, the impact of amalgam use in dentistry is minimal. The purpose of this paper is to examine on studies that relate mercury levels in human to the presence of dental amalgams. It is concluded that even though mercury used in filling is hazardous, if normal occupational recommendations for proper mercury hygiene routines and source of reduction strategies are followed, no occupational health risk can be assumed.
