<![CDATA[Background: Mastication process occurs over time and it can lead to occlusal reduction of the teeth. Thiscauses reducing occlusal contact of teeth and it will lead to disharmony occlusion disorders. The occlusiondisharmony is recognized by the body as a stressor that systemically affects the homeostasis in the body,especially the production of hormones.Objective: The aim of this study was to determine the systemic effect of occlusal disharmony on corticosteroneserum levels in Rattus norvegicus.Method: The research method of this study used experimental design and conducted among 7 male RattusNorvegicus in each groups. In intervention group, an occlusal reduction was ± 1 mm in all molars andfor control group did not given any intervention. Moreover, at 1st day, 7th day, 14th day and 21st day wastaken 2 cc of blood via infraorbital vein. The measurement of Corticosterone levels used Enzyme LinkedImmunosorbent Assay (ELISA).Result: Anova test results showed that corticosterone levels was significant difference between each groups(p <0.05). Tukey HSD test showed there was a significant difference between intervention group and controlgroup on 1st day, in intervention group on 7th day (p <0.05).Conclusion. The results of this study showed that there were differences of corticosterone serum levelsamong mice who experienced occlusion disharmony so it concluded that the dental occlusion disharmonyhad a systemic impact to corticosterone serum levels in Rattus norvegicus]]>

<![CDATA[ABSTRACT Background: The main goal of orthodontic treatment is to obtain a normal relationship of the teeth with facial structures and it is generally accepted that orthodontic treatment will have effects on facial proportion. Nowadays, facial appearance has a big influence on someone's appearance. Aesthetic facial appearance will produce a proportional, harmonious, and youthful facial profile. Case: this case report aims to describe that non extraction orthodontic treatment in class I malocclusion with mild crowding and mildline shift is a treatment with considerable success. Case management: A 19 years old female came with a chief complaint of crowding in upper and lower jaw. Intraoral examination revealed bilateral Class I molar and canine relationship. Patient had crowding in upper and lower jaw, and midline shift in lower jaw. Extra oral findings included a flat profile with competent lips. Cephalometric analysis showed skeletal class I with orthognati maxilla and mandible. Patient was bonded with 0.022-inch MBT brackets orthodontic appliance without extraction. After 20 months of treatment, an ideal arch coordination was achieved, the patient felt confident and satisfied with the treatment outcome. Conclusion: Decision to extract a tooth has to be made, not only by considering the amount of crowding, but also the eventual influence of orthodontic tooth displacement on the soft tissue surface of the face. Keywords: Crowding, Midline shift, Non – extraction.]]>

<![CDATA[Background: Mechanical force of orthodontics causes changes in periodontal ligament vascularization and blood flow, resulting in biochemical and cellular changes as well as changes in the contour of the alveolar bone and in the thickness of the periodontal ligaments. Hyperbaric oxygen (HBO) therapy is one of many solutions stimulating the growth of new blood vessels and increasing tissue oxygenation. Thus, HBO plays a role in recovery of periodontal ligament and osteoblasts. Purpose: This study aimed to determine the effects of HBO therapy for seven days on periodontal ligament size and osteoblast number in the tension site during bone remodeling in tooth movement. Method: The study was true experimental laboratories with completely randomized control group post test only design. Twenty-four males guinea pigs were randomly divided into three groups. K0 was the control group without any treatment, K1 was the group given a mechanical orthodontic pressure, and K2 was the group treated with the addition of hyperbaric oxygen therapy. The maxillary incisors were moved distally by elastic separator. After HBO therapy on day 7, all of the groups were sacrificed, and then periodontal ligament size and osteoblast number were analyzed by one-way Anova and LSD statistical tests. Result: The results showed significant differences in the size of the periodontal ligament and the number of osteoblasts in the tension site among the groups (p<0.05). Conclusion: HBO therapy at 2.4 ATA for 7 days is effective in recovery of periodontal ligament and increased osteoblast number during bone remodeling in tension area of orthodontic tooth movement.]]>

<![CDATA[Background: Orthodontic tooth movement will be followed by periodontal ligament and alveolar bone remodeling. Orthodontic mechanical force (OMF) will be distributed through the teeth to periodontal ligament and alveolar bone and then will generate local pressure resulting in bone resorption and tension areas that will form new bone. Robusta coffee contains caffeine, chlorogenic acid and caffeic acid. Caffeine may increase osteoclastogenesis, and caffeic acid has antioxidant effects that may reduce oxidative stress in osteoblasts. Purpose: This study conducted to analyze the effect Robusta coffee steeping on levels of RANKL and TGF-β1 in orthodontic tooth movement. Method: 16 male rats were divided into 2 groups. Group C: rats given OMF, Group T: given OMF and coffee brew at 20 mg/ 100 g BW. OMF in rats was conducted by applying ligature wire on the molar-1 (M-1) and both incisivus of right maxilla. Subsequently, M-1 of right maxilla was moved to mesial with a Niti closed coil spring. Observations were made on days 15 and 22 by taking the GCF by putting paper point on the gingival sulcus of mesio- and disto-palatal areas of M-1 of right maxilla to determine the levels of RANKL and TGF-β1 using ELISA method. Result: The administration of coffee brew was effective to increase levels of RANKL and TGF-β1 in the compression and tension areas (p <0.05). RANKL levels in compression area were higher than in the tension area (p <0.05), while the levels of TGF-β1 in the tension area were higher than in the compression area (p <0.05). Conclusion: The administration of coffee brew was effective to increase the levels of RANKL and TGF-β, therefore it might improve alveolar bone remodeling process.]]>

<![CDATA[Background: A pembarong performer is a reog dancer who bites on a piece of wood inserted into his/her mouth in order to support a 60 kg Barongan or Dadak Merak mask. The teeth supporting this large and heavy mask are directly affected, as the strong bite force exerted during a dance could affect their vertical and sagital facial dimensions. Purpose: This study aimed to examine the influence of the bite force of pembarong performers due to their vertical and sagital facial dimensions. Methods: The study reported here involved fifteen pembarong performers and thirteen individuals with normal occlusion (with specific criteria). The bite force of these subjects was measured with a dental prescale sensor during its centric occlusion. A cephalometric variation measurement was subsequently performed on all subjects with its effects on their vertical and sagital facial dimensions being measured. Results: The bite force value of the pembarong performers was 394.3816 ± 7.68787 Newtons, while the normal occlusion was 371.7784 ± 4.77791 Newtons. There was no correlation between the bite force and the facial sagital dimension of these subjects. However, a significant correlation did exist between bite force and lower facial height/total facial height (LFH/TFH) ratio (p = 0.013). Conversely, no significant correlation between bite force and posterior facial height/total facial height (PFH/TFH) ratio (p = 0.785) was detected. There was an inverse correlation between bite force and LFH/TFH ratio (r = -.464). Conclusion: Bite force is directly related to the decrease in LFH/TFH ratio. Occlusal pressure exerted by the posterior teeth on the alveolar bone may increase bone density at the endosteal surface of cortical bone.]]>

<![CDATA[Background: In the oral cavity, orthodontic appliances come into contact with saliva which may cause corrosion capable of changing their surface morphology due to the release of metal ions. Surface roughness can influence the effectiveness of tooth movement. One of the ions possibly released when body fluid comes into contact with brackets and archwire is nickel ion (Ni). Ni, one of the most popular components of orthodontic appliances, is, however, a toxic element that could potentially increase the likelihood of health problems such as allergic responses during treatment. Purpose: The purpose of this study was to investigate the effect of different artificial salivary pH on the ions released and the surface morphology of stainless steel (SS) brackets-nickel-titanium (NiTi) and archwire combinations. Methods: Brackets and archwires were analyzed by an Energy Dispersive X-Ray Detector System (EDX) to determine their composition, while NiTi archwire compound was examined by means of X-ray Diffraction (XRD). The immersion test was performed at artificial salivary pH levels of 4.2; 6.5; and 7.6 at 37°C for 28 days. Ni ion release measurement was performed using an Atomic Absorption Spectroscopy (AAS). Surface morphology was analyzed by means of a Scanning Electron Microscopy (SEM). Results: The chemical composition of all orthodontic appliances contained Ni element. In addition, XRD was depicted phases not only NiTi but also Ni, Titanium, Silicon and Zinc Oleate. The immersion test showed that the highest release of Ni ions occured at a pH of 4.2, with no significant difference at various levels of pH (p=.092). There were surface morphology changes in the orthodontic appliances. It was revealed that at a pH of 4.2, the surfaces of orthodontic appliances become unhomogenous and rough compared to those at other pH concentrations. Conclusion: The reduction of pH in the artificial saliva increases the amount of released Ni ions, as well as causing changes to the surface morphology of brackets and archwires.]]>

<![CDATA[Background: Previous studies on root resorption were reviewed by panoramic radiographs. Cone-beam computed tomography (CBCT) showed that 41.5% of teeth experienced resorption when panoramically examinated, while 68% of teeth experienced resorption when the examination method used was CBCT. Root resorption occurs in the maxillary central incisor (as much as 74%) and in the maxillary lateral incisor (as much as 82%). The maxillary canines have the most resorption, followed by the lateral maxillary incisors. Purpose: The aim of this study was to determine the differences of apical resorption in anterior maxillary teeth before and after orthodontic treatment in skeletal Class I/II cases of extraction. Methods: Samples from this study were the results of panoramic photographs of 50 patients treated by fixed orthodontic appliances at the Dental and Oral Hospital Airlangga University. These were selected according to the sample criteria. The evaluation method consists of measuring root and crown lengths with a digital application (RadiAnt DICOM Viewer). Subsequently, the measurements were evaluated using CBCT images. Results: The data were statistically analysed using normality tests with Shapiro–Wilk and Kolmogorov–Smirnov tests. Based on the results of paired sample tests, it was found that every treatment group had significant differences in the average length of the crowns and roots, with a result of p=0.000 (p<0.05). Conclusion: The use of CBCT is considered quite effective and accurate in evaluating root resorption compared to panoramic photographs.]]>

<![CDATA[Background: Dental anomalies usually lead to complicated decisions having to be made in terms of the orthodontic treatment of permanent dentition; tooth rotation is the most common of these irregularities. The prevalence rate of this phenomenon is 2.1–5.1% in patients who have not received orthodontic treatment. Purpose: This case report aimed to manage the complete bilateral rotation of maxillary canines with couple force by using a Nance appliance modification. Case: A 17-year-old male patient came in wanting to straighten his teeth. He complained about his bilateral canines, which were not in a normal position. There was an impacted left maxillary second premolar and an ectopically erupted right maxillary first premolar. He also had protrusions in the upper and lower anterior teeth and crowding in the lower anterior teeth as well as upper and lower midline deviations. Case Management: A clinical examination showed a class I relationship between the dental and cephalometry measurements and highlighted a class I skeletal pattern. The upper right first premolar was extracted and the left second premolar had undergone an odontectomy to allay protrusion and correct crowding. Bilaterally rotated upper canines were derotated using a modified Nance appliance and an elastomeric chain with couple force. Conclusion: The success of the orthodontic treatment was influenced by the specific nature of the patient’s dental and medical history, extraoral and intraoral examination, diagnosis and treatment planning, which was followed by a systematic approach to treatment. The Nance appliance modification reduced the total treatment time by achieving controlled anchorage and derotation of the canines.]]>

<![CDATA[Background: Management of bimaxillary protrusion can be challenging and should be used with maximum anchorage to prevent loss of anchorage and improve the facial profile. In addition, a patient with a missing molar is often found in a dental clinic. Space closure can cause tipping movement rather than bodily, so couple force should be used. Purpose: This case report aims to manage the bimaxillary protrusion with a missing molar using a T-loop and a transpalatal arch (TPA) as maximum anchorage for correction of the facial profile and couple force to create bodily movement for the space closure of a missing first molar. Case: A 21-year-old female patient complained about her protruding teeth. An intraoral examination indicated Angle’s Class I malocclusion on the left molar relation, with the lower-right first molar missing, mild crowding maxilla and mandible, 6 mm of overjet and 5 mm of overbite, and midline shift at the maxilla and mandible. Case Management: The treatment plan was the extraction of teeth 14, 24, 34; alignment with pre-adjusted McLaughlin Bennett Trevisi (MBT) 0.022; retraction of the anterior segment with a T-loop, TPA, and close spacing of the missing first molar with couple force on the buccal and lingual side and tip back. Retention was done with removable retainers. At the end of the treatment, normal incisive inclination and closed space of the missing first molar were achieved, along with an improvement of the facial profile. Conclusion: Bimaxillary protrusion can be successfully treated by means of extraction of the premolar(s), space closure for correction of the profile with T-loop and TPA, and closing the space of the missing molar with couple force on the buccal and lingual sides and tip back.]]>
