Prevention of dental caries and periodontal disease with health promotion has been the main goal of Dentistry, since the dental plaque is a common and predominating factor leading to loss of teeth both caused by both dental caries and periodontal disease. Most devices used for plaque removal and periodontal care are based on mechanical action, including toothbrushes, interdentally brushes and oral irrigators. Today, plaque control is facilitated by an increasing variety of active agents based on either natural ingredients or synthetic product. Alternative materials based on essential oil and plant extracts are therefore of particular interest. The aim of the present study was to investigate the different of zone inhibition of Streptococcus mutans of herbal toothpastes. Samples of the subjects were 4 types of herbal toothpastes and 1 herbal toothpaste as control. For inhibition zone trial toward Streptococcus mutans, agar diffusion method was used and the interpretation was done by measuring the widest inhibition zone. The result of the study indicated a statistical significance different on inhibition zone among the 5th toothpastes, but toothpaste containing siwak was the widest inhibition zone.

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.

Light-cured resin composite is one of the most commonly used molding materials due to its easy-to-mold characteristic. Nevertheless, care must be taken while treating this material, especially with respect to material thickness and how long it is exposed to light. Failure to treat the material with these optimal parameters will result in undesired hardness. To determine the most favorable value of these two parameters, an experiment was done with 3 different material thicknesses, and 3 different exposure times. After the sample of the resin composite was removed from its molding, it was stored under humid condition for 24 hours. Afterwards hardness test was done on the sample using Micro Vickers Hardness tester from this experiment, the significant difference in hardness was obtained and the maximum hardness was evaluated from the resin composite sample with 2 mm thickness and 60 seconds light exposure.

Oral squamous cell carcinoma (OSCC) is the result of accumulation genetic lesion and caused by specific mutation in specific key regulation genes. p53 gene is key target specific regulatory genes which function as negative regulators in cell cycle control. The highest mutation rates found in human cancers and the etiology in high risk populations and the pattern of molecular pathogenesis mechanism involved in the OSCC remain unclear. The purpose of this study was to determine the presence of alteration or mutation of p53 gene and to associate these mutations histopathological status of the patients such as well differentiated and poorly differentiated in OSCC in order to elucidate the molecular pathogenesis mechanism of OSCC based on the pattern of p53 gene. Using 40 untreated well and poorly differentiated OSCC biopsy samples and 16 normal patients were analyzed for the presence of mutation in the conserved region of the p53 gene exons 5 and or 7 by PCR-SSCP mutational analysis for p53 gene showed 70% of total samples : exon 5: 27.5% with heterozygous mutation 81.8%, exon 7: 55% with heterozygous mutation 100%. The incidence of p53 mutation was not significantly associated with well and poorly differentiated OSCC with the exception in exon 5 of p53 gene (p = 0.013) using contingency coefficient. This study concludes that mutation of p53 gene especially in exon 7 may not indirectly play in the progressivity of OSCC with the exception of mutation in exon 5 of p53 which indicates the essential role in the progressivity of OSCC.

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.

Previous research has indicated that there were several reactions in cellular activity and periodontal ligament collagen fibre as a response after orthodontic force application. Cementum has function to give attachment to collagen fibres of the periodontal ligament, maintaining the integrity of the root, helping to maintain the tooth in its functional position in the mouth, and being involved in tooth repair and regeneration so in the orthodontic tooth movement can induce changes in the cementum. The aim of this research is to investigate that fixed orthodontic appliance can change the amount of periodontal ligament collagen fibre and the thickness of inserting periodontal ligament fibre bundles at pressure site of cementum. This experimental study was held in laboratory with post test only control group design. Twenty two (22) premolar sample from 11 patient were divided into 2 groups. K group as control group (without treatment) and P group as treatment group (with using fixed orthodontic appliance). The amount of periodontal ligament collagen fibre and thickness of inserting periodontal ligament fibre bundles was examined by light microscopy and measured by image tool program. In the summary, there are increasing amount of periodontal ligament collagen fibre and the thickness of inserting periodontal ligament fibre bundles at cementum pressure sites as a normal response to remodeling and regenerating to orthodontic appliance and have function for strengthen adhering tooth cementum to the periodontal ligament.

Background: Tooth extraction, a common procedure in dentistry, can cause bone resorption during socket healing. Therefore, it is important to perform socket preservation procedure to maintain alveolar bone. Providing a combination of mangosteen peel extract with demineralized freezed-dried bovine bone xenograft (DFDBBX) in tooth extraction socket was expected to accelerate alveol bone formation. Purpose: This study aims to determine the effect of mangosteen peel extract combined with DFDBBX introduced into the socket of post tooth extraction on the formation of osteoblasts and osteoclasts. Method: Twenty-eight (28) Cavia cobayas were divided into four groups. Extraction to the lower left incisor of Cavia cobaya was performed. The extraction socket was filled with 25 gram of PEG (group I) as a control, active materials consisted of mangosteen peel extract and DFDBBX 0.5% (group II), active materials consisted of mangosteen peel extract and DFDBBX 1% (group III), and active materials consisted of mangosteen peel extract and DFDBBX 2% (group IV). After thirty days, those Cavia cobayas were sacrificed. By using HE on Histopatological examination, the number of osteoblasts and osteoclasts were measured by light microscope with 400 times of magnification. The statistical analysis was then performed using oneway Anova & TukeyHSD test. Result: The component active materials consisted of mangosteen peel extract and DFDBBX 2% had the most significant results related to the formation of osteoblasts and osteoclasts. Conclusion: Mangosteen peel extract combined with DFDBBX can increase osteoblasts and decrease osteoclasts in the socket of tooth extraction in Cavia cobaya. The combination of mangosteen peel extract and DFDBBX 2% is the most effective material in increasing osteoblast and decreasing osteoclast.

Since most authors use the reversible pulpitis and irreversible pulpitis classification, however, many dentists still do not implement these new classifications. Research was made using a descriptive method by proposing questionnaire to dentists from various dental clinics. The numbers of the dentists participating in this research are 22 dentists. All respondents use the diagnosis sheet during their examinations on patients. Nonetheless, it can't be known what diagnosis card used and most of the dentists are still using the old classification. Concerning responses given towards the new classification: a) the new classification had been heard, however, it was not clear (36.3%); b) the new classification has never been heard at all (63.6%). Then, responses concerning whether a new development is important to be followed-up or not: a) there are those who think that information concerning new development is very important (27.2%); b) those who feel that it is important to have new information (68.3%); c) those who think that new information is not important (8%). It concluded that information concerning the development of classification of pulp inflammation did not reach the dentists.

Dental plaque is the primary etiological factor in periodontal diseases. However, there are many factors that can modify how an individual periodontal tissue will respond to the accumulation of dental plaque. Among such risk factors, there is increasing evidence that smoking tobacco products alters the expression and rate of progression of periodontal diseases. The aim of this study was to find out the loss of periodontal tissue adhesion in smokers by measuring pocket depth using probe, and by measuring alveolar bone damage using Bone Loss Score (BLS) radiographic methods on teeth 12, 11, 21, 22, 32, 31, 41, 42. Based on T Test statistical analysis, there were significant differences in pocket depth damage of alveolar bone in smokers and non smokers. In conclusion there were increasing pocket depth and alveolar bone damage in smokers.

Background: Cemento-ossifying fibroma is a benign neoplasm characterized by replacement of normal bone by fibrous tissue and varying amounts of newly formed bone or cementum-like material, or both. The cemento-ossifying fibroma has caused considerable controversy because of confusion regarding terminology and the criteria for its diagnosis. In addition, the cemento-ossifying fibroma often shows variations in clinical, radiographic, and histopathologic features, hence require different treatment options. Purpose: This paper attempts to elaborate the classification and terminology of cemento-ossifying fibroma of the jaw, the clinical characteristic, radiographic, and histopathologic features, the different tumor behaviors, and the surgical treatment modalities required. Case: Two patients diagnosed with cementifying fibroma and two patients with ossifying fibroma were reported, presenting their clinical presentation, diagnostic imaging, and histopathology reports, as well as their surgical treatments. Classifications of fibro-osseous lesion of the jaws and characteristics as well as variations in several aspects of cemento-ossifying fibroma of the jaws are discussed. Conclusion: The diagnosis of cemento-ossifying fibroma of the jaw can be established quite consistently based on clinical, radiographic, and microscopic features. However, these tumors may exhibit variations in their neoplastic behaviors. It is therefore important to take into account the individual tumor behavior when one is planning a proper surgical treatment. The behavior of the tumor governs the required surgical treatment which may range from simple curettage of the tumor to radical resection of the jaw.
