<p><strong><em>Background: </em></strong><em>Oral habits include habit which are continuously done and has the potential to cause defects on teeth and perioral tissues.Lip sucking or biting habits are often found simultaneously or as a substitution of finger sucking. This habit may affect the labial and perioral structures. The habit may take </em><em>several</em><em> forms. Two extreme types are mild wetting</em><em> of</em><em> the lips with the tongue and pulling the lips into the mouth between the teeth. The lip bumper is a functional device that is used successfully to intercept developing dental and occlusal problems by allowing a proper development of the arch length and width for eruption of the permanent teeth.</em><strong><em>Purpos</em></strong><strong><em>e:</em></strong><em> This study aimed to re-validate the effectiveness of lip bumper application and habitual therapy in treating the bad habit of lip sucking. <strong>Case Report:</strong> The mother of a 9-year-old girl reported an upper front teeth protrusion and frequent occurrence of mouth ulcer. Further examination revealed that the patient had a habit of lip sucking. </em><strong><em>Case Management</em></strong><strong><em>:</em></strong><em> Removable Lip Bumper is used to control lip habits such as lip sucking and to improve mentalis muscle hyperactivity. Such habit was treated with the use of a removable lip bumper and habitual therapy conducted by both parents. Constants reminder and encouragement from the parent to wear the lip bumper is one of the key success factors in this treatment. <strong>Conclusion: </strong>Five months after the initial application of a lip bumper and habitual therapy, the patient overcame the habit of lip sucking.</em></p><p><strong><em>Keywords</em></strong><strong><em>:</em></strong><em> lip bumper, lip sucking, myofunctional therapy</em></p><p><strong><em>Correspondence</em></strong><strong><em>:</em></strong><em> YulieEmildaAkwan, </em><em>Department of Pediatric Dentistry</em><em>, Faculty of Dentistry, Hang TuahUniversity, Arif Rahman Hakim 150, Surabaya, Phone 031-5945864, Email: <span style="text-decoration: underline;">yulieemilda@yahoo.com.</span></em></p>
Background: Antibacterial is a substance produced by a microorganism, which has the ability to inhibit growth or kill other microorganisms. Antibacterial activity is measured in vitro to determine the potency of an antibacterial agent in a solution, its concentration in body fluids or tissues, and the susceptibility of certain microorganisms to certain concentrations of drugs. Purpose: The purpose of this research was to find the power of extract ethanol Nannocholoropsis oculata as an alternative antibacterial causes of the growth of the caries which is Streptococcus mutans. Material and methods: extract ethanol. Nannocholoropsis oculate divided into three parts of concentration 1,5%, 2% and 2,5%, Chlorhexidine 0,12% as a control, culture bacteri Streptococcus mutans with McFarland 0.5 standart. The metode used in this study was One way analysis of varians (ANOVA), but first it had to be a homogenius test and a normalitas test. Result: The result of this study showed that no barrier power at concentration 1,5%, 2% and 2,5%. Conclucion: The result showed no inhibition in the three observed groups of 1.5%, 2%, and 2.5% of extract ethanol Nannochloropsis oculate. This meant that this article cannot prove the inhibition characteristic of Nannochloropsis oculate. This may be because the concentration of the extract Nannochloropsis oculata used in this study was too small. Henceforth, it is necessary to conduct research with a higher concentration of extract. On the other hand, the positive control group, using 0.12% Chlorhexidine solution, showed an inhibition characteristic while the negative control group, using 1 % of DMSO showed no inhibition.
Background: Application of fissure sealants to young permanent teeth is one of the preventive measures for caries in the field of dentistry. Fissure sealants based on glass ionomer cement (GIC) have the advantage of releasing fluoride. Sodium fluoride and acidulated phosphate fluoride (APF) are remineralization agents because they can increase remineralization by altering hydroxyapatite to fluorapatite and this in turn makes fluorine able to increase pH. Fluoride can prevent caries by increasing remineralization of the enamel that has just been demineralized by acids produced by plaque bacteria. The aim of this study is to compare the shear bond strength fissure sealant based on glass ionomer between sodium fluoride and APF topical fluor application Method: This research applied true experimental design with post test only control group design. The 21 maxillary permanent premolars were distributed into 3 groups, namely the control group (K1), the treatment group added 5% sodium fluoride (K2), and the treatment group added 1.23% APF (K3). Result: One Way ANOVA and post hoc LSD analysis test displayed no significant difference in each group. This could be due to the material used as a conditioner prior to the GIC application. The addition of fluoride ions will inhibit the demineralization process of the enamel produced by the application of conditioner. So it does not rule out that it will interfere with the attachment of the GIC material used as a fissure sealant in this research. Conclusion:There was no significant difference in shear bond strength of fissure sealant based on glass ionomer between sodium fluoride and acidulated phosphate fluoride topical application.
