Background: Several processes in a teeth treatment often inflict wound in gingiva. Collagen is the key component of the wound healing. The collagen roles in advancing wound healing particularly, triggering the synthesis to induces collagen and cellular migration, and also inducing clotting cascades. Wound treatment using natural product is potential in accelerating wound healing, in particular duck egg membrane which contains collagen, glucosamine, and hyaluronic acid. This study aims to find out the influence of gel extract application of duck egg shell membrane 10 % towards collagen solidity on gingiva wound recovery process (study of Rattus norvegicus). Method: The subjects of the study consist of 20 male Rattus norvegicus aged 2-3 months which were given wound on labial gingiva of the maxillary central incisors with punch biopsy. The samples were divided into 2 groups, they were positive control group (Aloclair Gel

The bidara plant (Ziziphus mauritiana Lam) is widely distributed in various Asian countries. Bidara leaves contain secondary metabolites, the main content of which is flavonoids. As a gram-negative anaerobic bacteria, Porphyromonas gingivalis is one of the normal flora of the oral cavity. However, over quantities of this bacteria can promote chronic periodontitis. This research aims to analyze the bidara leaf ethanolic extract as an inhibitory agent of Porphyromonas gingivalis. This research design is experimental laboratory research with a post-test controlled group of Porphyromonas gingivalis inhibition. A total of 25 samples consisted of 5 groups of ethanol extract of bidara leaves at concentrations of 1%, 3%, 9%, positive control betel leaves, and negative control aquadest. Bacteria incubation was held for 48 hours, and the free bacterial zone was analyzed by the One Way ANOVA test. The results of the analysis showed that there was a significant difference between the control group and the treatment group. This study concludes that the ethanol extract of bidara leaves had a strong inhibitory effect on Porphyromonas gingivalis.

Background: Traumatic ulcer is one of the most common oral mucosal lesions, which are caused by physical trauma. The prevalence of traumatic ulcers in this world is 83.6%. Ulcers cause pain, difficulty in articulation, mastication and swallowing causing discomfort to the patient. The aim of this study is to analyze the effect of nano chitosan mouth spray on epithelial thickness in the healing process of traumatic ulcers. Methods: This research was true experimental type using post test only control group design with the number of samples are 27 rats divided into three groups. The treatment group was given nano chitosan mouth spray, the positive control group was given aloclair plus spray and the negative control group was given aquadest. After 7 days of treatment, the ulcer tissue was observed using a light microscope, then the average thickness of the epithelium was calculated. They were then analyzed using one-way ANOVA and LSD tests. Results:The results showed difference in the average value of each group. The treatment group is higher than the positive control group and the negative control group with an average epithelial thickness (19.42 ± 2.11). Meanwhile, the negative control group is the lowest group among the three groups with an average epithelial thickness (5.72 ± 0.77). The results based on the One Way Anova parametric test, the value of p = 0.000 (p <0.05) Conclusion: The conclusion obtained is that there is an effect of chitosan nano mouth spray on epithelial thickness on the healing process of traumatic ulcers in male Wistar rats after 7 days of treatment.

Radiograf panoramik digital digunakan dalam membantu mendiagnosis impaksi gigi molar tiga. Pola sidik jari (dermatoglifi) dihubungkan dengan kelainan dalam bidang kedokteran gigi dan tingkat kecerdasan seseorang. Tingkat kecerdasaan diukur menggunakan intelligence quotient (IQ) test. Tujuan penelitian ini adalah untuk mengetahui hubungan impaksi gigi molar tiga dengan pola sidik jari, hubungan pola sidik jari (dermatoglifi) dengan intelligence quotient (IQ), dan hubungan impaksi gigi molar tiga dengan intelligence quotient (IQ).Penelitian ini menggunakan 43 responden yang dilakukan pengambilan foto radiografi panoramik untuk melihat ada tidaknya impaksi gigi molar tiga dan dilakukan pengambilan pola sidik jari dari sepuluh jari tangannya. Setelah itu, peneliti melakukan pengambilan data IQ pada responden. Data dianalisis dengan uji koefisiensi kontingensi.Hasil penelitian mengenai hubungan antara impaksi gigi molar tiga dengan pola sidik jari (dermatoglifi) didapatkan nilai p 0.013. Hasil penelitian mengenai hubungan antara impaksi gigi molar tiga dengan IQ didapatkan nilai p 0.875. Hasil penelitian mengenai hubungan antara pola sidik jari (dermatoglifi) dengan IQ didapatkan nilai p 0.703. Kesimpulan penelitian ini adalah terdapat hubungan antara impaksi gigi molar tiga dengan pola sidik jari (dermatoglifi), namun tidak terdapat hubungan antara impaksi gigi molar tiga dengan IQ, dan tidak terdapat hubungan antara pola sidik jari (dermatoglifi) dengan IQ
