A number of investigations have shown a positive correlation between the number of Streptococcus mutans (S. mutans) in dental plaque and the prevalence of dental caries. Consequently, this microorganism has been the prime target for the prevention of dental caries. Propolis being a substance made by the honeybee, is a potent antibacterial agent. The main chemical class present in propolis is flavonoids. Flavonoids are well-known plant compounds that have antibacterial property. Because S. mutans is accepted to be one of the microorganisms responsible for dental caries and flavonoids in propolis are antibacterial, the purpose of this study was to evaluate in vitro the antibacterial activity of flavonoids Trigona sp propolis against S. mutans as a first step in its possible use as an alternative anticaries agent. Extract flavonoids was purified from ethanol extract of propolis which was obtained from Bulukumba Regency South Sulawesi using thin layer chromatography. The purification of flavonoids was carried-out by UVradiation at λ max 254 nm and λmax 366 nm and treatment with ammonia. Extract flavonoids was diluted in aquadest to 0.05%; 0.075%; 0.1%; 0.25%; 0.5%; 0.75% concentrations. Aquadest and 10% Povidone iodine were also used as control solution. S mutans were grown in medium glucose nutrient agar and incubated with flavonoids for 24 and 48 hours, at 37° C. Antibacterial activity was reflected by the diameter of the inhibition zones around the stainless steel cylinder. The data were analyzed by using ANOVA followed by LSD test with significance level of 5%. The results of this study showed that after being incubated for 24 and 48 hours, all flavonoid concentrations significantly (p < 0.05) inhibited the growth of S mutans. 0.1% flavonoid was the most effective concentration to inhibit the growth of S mutans after 24 hours of incubation and 0.5% flavonoid after 48 hours of incubator.

Background: Elimination of subgingival plaque for prevention and treatment of periodontal diseases through scaling is a routine procedure. It is also well-known that periodontal disease is related to systemic diseases. Nevertheless, the idea how scaling procedures also able to reduce allergic symptoms i.e. eczema and asthma, is not easily accepted, because it is contradictory to the “hygiene hypothesis”. However, since allergic symptoms also depend on variable factors such as genetic, environmental and infection factors; every possible effort to eliminate or avoid from these factors had to be considered. Subgingival plaque is a source of infection, especially the Gram-negative bacteria that produced endotoxin (lipopolysaccharides, LPS), a potential stimulator of immunocompetent cells, which may also related to allergy, such as mast cells and basophils. In addition, it also triggers the “neurogenic switching” mechanism which may be initiated from chronic gingivitis. Objective: This case report may explain the possible connection between subgingival plaque and allergy based on evidence-based cases. Case: Two adult siblings who suffered from chronic gingivitis also showed different manifestations of allergy that were allergic dermatitis and asthma for years. They were also undergone unsuccessful medical treatment for years. Oral and topical corticosteroids were taken for dermatitis and inhalation for asthma. Case Management: Patients were conducted deep scaling procedures, allergic symptoms gradually diminished in days even though without usual medications. Conclusion: Concerning to the effectiveness of scaling procedures which concomitantly eliminate subgingival plaque in allergic patients, it concluded that this concept is logical. Nevertheless, further verification and collaborated study with allergic expert should be done.

Probiotic therapy is one of the therapies to prevent dental caries prospectively. Such therapy has been used in the medical area but not in dentistry. Probiotic therapy is important to be done since this therapy study ecosystem in oral cavity which has many commensal bacteria more detail. The probiotic material used to prevent dental caries is the microorganism which counter microorganism causing dental caries and its virulent product (acid lactic). Veillonella sp. use lactic acid as the end product of S. mutans which cause the dental caries. The principle of probiotic therapy is the comensalism symbiosis found in oral cavity ecosystem. Veillonella sp could be added to anticipate the lactic acid which cause enamel demineralization. Hopefully dentist will apply probiotic therapy, so there will be more study of Veillonella sp. as probiotic material for dental caries prevention. Further research on Veillonella sp in probiotic therapy and Immunology need to be done to achieve the balance of ecosystem.

Allergic rhinitis is one of the most common ailments in children. In clinical practice approximately 50% of patients with symptoms of rhinitis are diagnosed with non-allergic rhinitis. Positive skin prick test or specific IgE in vitro tests that are relevant to aeroallergens are conclusive diagnostic of allergic rhinitis. However, simple diagnostic method such as "sneezing sign" has already proved to be reliable. Hypersensitive children have humoral immune system (Th2) which release inflammatory factors in the presence of allergen or infection that contribute to allergic response. Immunological reactions occurred and antibodies concentration arise, especially specific IgE instead of IgG because of the isotype switching. A lot of procedures such as allergen avoidance, medication and immunotherapy were done in allergic rhinitis management. However, oral plaque controls were not the point of interest in this case. The aim of this study is to find out the effectiveness of oral plaque control in the reduction of severity of allergic rhinitis symptoms using symptom scores. Fifty children, male and female aged 8–14 years, subjective diagnosed as allergic rhinitis using "sneezing sign" were included in this study. Oral plaque control procedures were done by polishing and flossing followed by 4 days of gargling with 1% povidone iodine. Clinical result showed that after 3 days, oral plaque control 2.925 times more effective than control group. The conclusion was oral plaque control is effective reducing the severity of allergic rhinitis symptoms.

Cold curing acrylic is more porous, having more residual monomer and dimensional change. Physical property of cold curing acrylic shows to have very small dimensional change resulted from imperfect polymerization process and if dimensional change occurs, it would cause improper use of orthodontic appliance. Orthodontic acrylic base plate which is made of cold curing acrylic, in order to achieve good result, it is suggested to use hydro flask or polyclav with water temperature 45°–50°C and polyclav and pressure in 2–3 atm during polymerization process. Even though cold curing acrylic could polymerization at room temperature, the purpose to use hydro flask or polyclav is to reduce residual monomer and porosity. The purpose of the present study is to know the difference in dimensional accuracy of orthodontic acrylic at various polymerization temperature. The samples of the study were 18 acrylic base plate sized 65 × 10 × 25 mm classified into 3 control groups with polymerization temperature at 30° C, 40° C and 50° C. Measurement was done using caliper in order to know dimensional accuracy of orthodontic acrylic. The measurement result was tabulated and One-Way ANOVA test one was done with significant level 95%, the probability result 0,0055 was found which means there was significant difference among each control group. LSD test showed that group I polymerization at 30° C, group II polymerization at 40° C, and group III polymerization at 50°C there was significant difference. The conclusion of this study is : dimensional difference of orthodontic acrylic base plate on polymerization at group I at 30° C, group II at 40° C, and group III at 50° C water temperature and could achieve better dimensional accuracy comparing with polymerization at 50° C.

Background: Bone graft material have been used extensively in bone healing and periodontal treatment. Alloplast such as hydroxyapatite are frequently used to repair and reconstruct bone defects. By merely applying hydroxyapatite for the treatment of bone is not fully effective yet to produce new bone regeneration. Locally applied high molecular hyaluronic acid (HA) has been shown to stimulate differentiation and migration of mesenchymal cells. Recent studies on regenerative surgical procedures indicate that reduction of bacterial burden at the wound site may improve the clinical outcome of regenerative therapy. Metronidazole has the greatest bacteriostatic effect. A clinical application of HA metronidazole gels during the surgical therapy may reduce the bacterial contamination of surgical wound site. Purpose: The purpose of this study was to examine the effect of combination hydroxyapatite and HA metronidazole gel 1% on osteoblast cell number after wound healing process in the wistar rats incisor tooth extraction socket. Method: Twenty seven wistar rats were divided randomly into 3 groups. The first group consisted of wistar rats given hydroxyapatite were subjected to the mandibular incisor extraction socket. The second group were given hydroxyapatite combined with HA metronidazole gel 1%. The control group were filled with blood. Wistar rats were euthanized on day 14 and then preparation for histological examination was stained using hematoxylin-eosin and then the numbers of the osteoblasts were calculated. Result: The differences in each group were tested by one way Anova test (α=0.05). The numbers of osteoblasts in each group had a significant difference (p<0.05): the highest numbers of osteoblasts were found in the group that was given hydroxyapatite combined with HA metronidazole, followed by the lower numbers of osteoblasts in the hydroxyapa ite group and the lowest numbers of osteoblasts were found in the control group. Conclusion: Adjunctive application of HA metronidazole to hydroxyapatite after tooth extraction increase the number of osteoblast in the treatment of bone defects on a wistar rat model.

Oral tongue cancers are characterized by a high degree of local invasion and a high rate of metastases to the cervical lymph nodes. Also, treatment options for this cancer are limited. However, a new strategy for refractory cancer, gene therapy is watched with keen interest. Recently, a novel method for high-efficiency and region-controlled in vivo gene transfer was developed by combining in vivo electro-gene therapy and intratumoral plasmid DNA injection. In the present study, a nonviral gene transfer system, in vivo electrogene therapy in human oral tongue cancer cell, SP-C1 xenograft was examined. The aim of the study is to examine the efficiency of transfection of exogenous p27Kip1 gene by electroporation and the antitumor activity of p27Kip1 gene therapy in human oral tongue cancer xenografts using pcDNA3.1-p27Kip1 wild type (wt) and pcDNA3.1 empty vector with the local application of electric pulses. To evaluate this in vivo gene transfer method, the enhanced green fluorescence protein (EGFP) gene was transfected into xenografts by electroporation. The efficiency of transfection of exogenous p27Kip1 gene by electroporation was confirmed by Western blotting analysis. To estimate the reduction of oral tongue cancer xenografts by this method, the size of SP-C1 xenografts in nude mice after electroporation with wild type p27Kip1 gene was measured. The growth of tumors was markedly suppressed by wild type p27Kip1 gene transfection by electroporation compared with transfection of empty vector only. Moreover, histological specimens revealed apoptotic cell death was increased in wild type p27Kip1-transfected tumors than empty vector. These results suggest that it is possible to transfer wild type p27Kip1 into human oral tongue cancer xenografts using electroporation. Wild type p27Kip1 has a high-potencially to suppress the growth of tumors. Finally, combination system of pcDNA3.1-p27Kip1 wt-injected tumor and electroporationmight be used for human oral cancer.

Muscular hypotonia is one of the clinical signs in patients with Down syndrome. As a characteristic of patients with Down syndrome, hypotonia is clearly evident in face expression and oral dysfunction. Dentocraniofacial growth abnormalities in patients with Down syndrome may be influenced by genetic and environmental factors. Stomatognathic system musculature as an environmental factor (factor outside the bone) can affect dentocraniofacial growth by orofacial muscles activities when chewing, swallowing, breathing, and speaking. Oral dysfunctions commonly seen in patients with Down syndrome are open mouth, protruding tongue posture, difficulties when chewing, swallowing, and speaking, drooling, and mouth breathing. The purpose of this study was to observe how the mastication muscular tone affecting the facial size of Down syndrome patient. Twenty five of 14–18 years old children with Down syndrome were diagnosed by clinical characteristic and cytogenetic examination. Mastication muscular tone was described by masseter and temporalis muscle synergy and oral function, whereas the facial size consisted of facial size of lateral, anteroposterior and vertical growth. The result of regression test revealed that the degree of mastication muscular tone has a significant effect on facial size of the anteroposterior growth and facial size of vertical growth, but did not significantly influence the facial size of lateral growth.

The high success rate of immediate implant placement both in the anterior and posterior regions were reported by many authors, therefore applying this techniques can be considered as a safe surgical procedure and minimizing the dental office visit for patient satisfaction. This paper reports the outcome of immediate placement of implants following extraction of anterior maxillary teeth. Combination technique of immediate and submerge implant placements including bone grafting procedure were used. Four implants with TiUnite surface type were placed immediately in two patients with the short-term result indicated that this technique may serve as a simple and safe procedure for immediate implant placement. It was concluded that immediate implant placement technique combined with TiUnite implant surface was successful in treating region directly after tooth extraction therefore this technique can be use as an alternative surgical method for dental implant rehabilitation.
