Background: Teeth discoloration is considered disturbing performance,therefore bleaching become an option for teeth whitening. Hydrogen Peroxide (H2O2) is commonly used, it is beneficial for teeth whitening but in other hand it has adverse effectin lowering micro hardness of the tooth. Hydrogen Peroxide can be found in pears. The objectives of this research were to determine the influences of application duration and immersion time of tooth when immersed in pear juice toward its discoloration and micro hardness.Method: An experimental study with pre-post test controlled group design were conducted using 28 premolars teeth which divided into four groups. Group A and Bwere immersed in pear juice with concentration of 100% for 30 and 60 minutes/day. Group C and D were immersed in H2O2 3% for 30 and 60 minutes/day each for 14 days. Tooth color and micro hardness of each tooth sample were recorded before and on 7thand 14thdays after immersion. The data was analyzed by friedman test, repeated anova, one-way anova and post hoc.Result: The average of tooth color index based on the duration of application in all four groups showed significant changes, while the average change in micro hardness index based on the duration of applications were shown significant difference only in group C and D. The difference of time immersion in pear juice 100% for 30 and 60 minutes had no effect on tooth discoloration and micro hardness.Conclusion: It can be concluded that pear juice can be used as an alternative material for bleaching process without deteriorating it’s micro hardness.
Background: The use of commercial desensitization toothpaste is one of the way to treat dentine hypersensitivity. Desensitization tooth paste contains an active ingredient which is able to occlude the dentinal tubules to minimize the movement of fluid in the dentinal tubules which lead to dentin hypersensitivity. Desensitization toothpaste containing various kind of active ingredients for occluding the dentinal tubules. The purpose of this research was to determine the differences of desensitization tootpaste ability (Pepsodent Sensitive Expert® and Sensodyne Repair and Protect®)inoccluding dentinal tubules with different active ingredient (hydroxyapatite and Novamin).Method: The research is experimental laboratories with post test group design. The sample used was 8 dentin disc with 8 mm length and 3 mm width, the sample was divided into two groups thattreated with Pepsodent Sensitive Expert® desensitization toothpaste and the group treated with Sensodyne Repair and Protect® desensitization toothpaste. A non-parametric data analysis was carried out by MannWhitney(<0.05). Result:The result showed that there were no significant differences in the percentage of dentinal tubulesin both treatment groups.Conclusion:The conclusion of this research is both of Pepsodent Sensitive Expert® and Sensodyne Repair and Protect® desensitization tootpaste have the same ability in occluding the dentinal tubules.
Background: Odontogram is one part of the dental record. The odontogram form isfilled with diagnoses and treatment done by the dentist. Odontogram can be used for the further treatment plan and help the forensic department to do the identification. The purpose of this study was to identify the completeness of odontogram filling out by the dentist in Semarang.Method: The research was descriptive using a cross-sectional study design. The subject of the research was graduated dentist in year 2015 until 2017. Subjects were chosen through information from PDGI.Result: The result of this study showed that none of the subjects filled odontogramcompletely, 5 subjects filled less complete and 39 others were categorized incomplete according to medical record guidance book published in 2015.Conclusion: Based on the study, concluded that the need to pay attention aboutthe importance of filling odontogram by the dentist was still low.
Background: Dentin hypersensitivity is a short sharp sense of pain in the teeth when exposed to excitatory stimulus. A total of 74% of world population experiencing dentin hypersensitivity. Home treatment topical desensitization is rarely found in Indonesia. The use of dentrifice is less practical because it must be done with regular brushing. Indonesia has abundant natural resources, one of which is purple sweet potato. Purple sweet potato (Ipomea Batatas P.) has highest potasium ions compared to other foodstuffs. Potassium ions can be a solution of dentin hypersensitivity by temporary blocking the suffix pulp nerve impulses. Purpose: The research objective was to determine the effectiveness of the 10% purple sweet potato extract gel of the dental pain threshold score. Method: An experimental study carried out by dental pain threshold score measurements using vitality tester into the teeth with gum recession. Samples included 32 respondents with a single blind and pre-post test control group design. They were divided into treatment group and negative control group. Paired T-test and Wilcoxon were used as data analysis. Result: The results showed dental pain threshold score increasing either in treatment group and negative control, although not as significant as in the treatment group. Conclusion: 10% purple sweet potato extract gel containing potassium ions is able to reduce the pain of dentin hypersensitivity.
Background: Streptococcus mutans is an oral cavity bacteria that is dominantly found. The acidogenic nature of bacteria can affect the damage to the physical and biochemical structures of dental biofilms. Streptococcus mutans growth becomes important to control. One way to control its growth is through the use of probiotic bacteria available in processed foods. The objective of this study is to investigate the effect of probiotic drinks against the Streptococcus mutans mutans. Method: This study is experimental research with a posttest-only group design, using two test groups. Streptococcus mutans suspension with McFarland turbidity standard of 0.5 in MRS Agar medium was placed on a paper disc that had been soaked in aqua dest (control group) or probiotic drink (treatment group) for ± 20 minutes and then incubated for 48 hours at 37oC. Each group was replicated 16 times. After incubation, the diameter of the Streptococcus mutans growth inhibition zone formed was measured using a caliper.Result: The control group did not show an inhibitory zone, while the treatment group resulted in a mean diameter inhibition zone of 1.18 mm. The Mann Whitney test proved that the treatment group had a significantly higher diameter of the inhibition zone compared to the control one (p=0.000).Conclusion: Probiotic drink had an inhibitory power on the Streptococcus mutans growth
Background: Oral disease still need special attention, especially in dentistry. Inflammation of the pulp is caused by the presence of irritants. One of the mechanical irritants is iatrogenic factors caused by operator error during preparation so that roof of pulp chamber is exposed. This condition is called reversible pulpitis/inflammation of the pulp. Cells that play a role during inflammation are macrophages which are the second defense cell after neutrophil apoptosis. A direct pulp capping procedure is indicated for this condition. The material commonly used is biodentin, but because the price tends to be expensive, alternative materials are needed. Siwak contains flavonoids which are known to play an important anti-inflammatory role in the healing of exposed pulp. The purpose of this study was to compare the number of macrophages in the dental pulp of rats with reversible pulpitis after administration of biodentin and siwak extract. Method: This research is a true experimental with a post test only group design, consisting of 2 treatment groups, namely the 75% siwak extract group and the biodentin group. The material is applied after the tooth has been prepared. The research sample used male wistar rats and sacrificed on the 3rd day. Samples were stained with Hematoxylin Eosin to see macrophage cells. Result: The data obtained were analyzed using the independent T-test. The test results showed a significant difference, with a value of p = 0.008 (p <0.05). Conclusion:The conclusion of this study that the siwak extract group showed a lower mean number of macrophage cells than the biodentin group. PENDAHULUANMenurut survei dari Kemenkes RI tahun 2011 menjelaskan bahwa penyakit pulpa dan periapikal menempati urutan ke -7 dari daftar penyakit yang termasuk rawat jalan di rumah sakit pada tahun 2010 1 . Pulpa gigi meliputi lebih dari satu lapisan yaitu lapisan odontoblas, lapisan cellfree zone, cell-rich zone, dan inti pulpa dengan macam-macam komponen di dalamnya seperti pembuluh darah, saraf, sel fibroblast, sel mesenkim, dan sel imun (makrofag dan limfosit) 2 . Pulpa mempunyai beberapa fungsi yaitu fungsi induktif, fungsi formatif, fungsi reparatif, fungsi nutritif, dan fungsi protektif 3 . Apabila ada stimulus atau substansi asing, pulpa gigi akan mengeluarkan respon imun sebagai perlawanan yaitu pulpitis atau peradangan pulpa 4 . Peradangan pulpa yang ringan atau sering disebut sebagai pulpitis reversible dapat kembali sembuh jika rangsangan dihilangkan 5 . Sel yang berperan pada saat terjadi
