The incisor has a variation of root canal morphology, which can be assessed using periapical radiography. Periapical radiography with standard angulation often makes complicates the assessment of the root canal morphology that is branched off in buccal and lingual directions because the radiograph result of the root canal will appear superimposed. Therefore, it is necessary to change horizontal angulation to mesial or distal to help assess the superimposed root canal. Root canal morphology may vary by population. The population in Indonesia consists mainly of the sub-races of Proto and Deutro-Malay. The purpose of this study was to determine the difference of root canal morphology between maxillary and mandibular incisors; between the sub-races of Proto and Deutro-Malay; and between the right and left regions, using twice the radiation projection. This study was an analytical study with cross-sectional method using 55 subjects who come from three previous generations of Proto and Deutro-Malay. On each tooth were performed twice radiations periapical radiography, using standard angulation and altering horizontal angulation toward distal 30Âº. The results showed that in Proto-Melayu, for maxillary central incisors maxillary teeth were obtained type I (99.1%) and III (0.9%) Vertucci, and maxillary lateral incisors were obtained type I Vertucci (100%). In mandibular central incisors were obtained type I (90%), II (3.6%), III (2.7%) Vertucci and IV Gulabivala (3.6%), and mandibular lateral incisors were obtained type I (87.3 %), II (1.8%), III (7.3%) Vertucci and type IV Gulabivala (3.6%). In Deutro-Malay, maxillary central incisors were obtained 100% Vertucci type I and maxillary lateral incisors were obtained type I (99.1%) and II (0.9%). In mandibular central incisors were obtained type I (85.5%), III (11.8%) Vertucci, IV Gulabivala (1.8%), and other types 1-2-1-2-1 (0.9%), and mandibular lateral incisors were obtained by type I (81.8%) and III (18.2%) Vertucci. The result of chi-square analysis showed there were no significant differences of root canal morphology of maxillary insicors tooth between Proto and Deutro-Malay and between right and left region (p> 0,05), but there were significant differences of root canal morphology between maxillary and mandibular incisors and root canal morphology of the mandibular incisor between Proto and Deutro-Malay (p <0.05). In conclusion, maxillary and mandibular incisors of Proto and Deutro-Malay sub-races have variations in root canal configuration and there were differences found in the mandibular incisors.

Anxiety is a subjective response in a harmless situation or an emotional problem which is caused by human themselves. Anxiety is a major contributor to the reluctance of people to get dental treatment. Dental anxiety was assessed by using Modified Dental Anxiety Scale (MDAS) that was remodified to match during tooth extraction and is widely spread in the internet. A total of 1298 responses were collected two months later. 11-20 years old age group is reported to be moderately anxious with a percentage of 43.51%, while 21-40 years old group and 41-65 years old group were found to be not anxious or slightly anxious with a percentage of 47.04% and 62.65% respectively. A total of 45.42% female were found to be moderately anxious while 52.75% of male were not anxious or slightly anxious. 52.63% of people from Indonesia East Time Zone were reported to be moderately anxious, meanwhile people from Indonesia West Time Zone and Indonesia Central Time Zone were not anxious or slightly anxious with a percentage of 46.05 and 52.41% respectively. The prevalence of dental phobia among people was 4.63%. In conclusion, dental anxiety were found higher in younger ages group, female and people from Indonesia East Time Zone. Kecemasan adalah respons subjektif seseorang bukan pada keadaan berbahaya atau masalah emosional yang penyebabnya adalah diri sendiri. Kecemasan adalah salah satu faktor besar dalam diri manusia yang mempengaruhi seseorang enggan mendapatkan pelayanan kesehatan gigi. Kecemasan dental diperoleh dengan menggunakan Modified Dental Anxiety Scale yangdimodifikasi sesuai dengan keadaan pencabutan gigi dan disebarkan melalui internet.

The appropriate planning of orthodontic therapy with regard to appliance selection, information on the patientâ€™s stage ofsomatic maturity is needed. Hand wrist maturity has been shown to be closely related with the pubertal growth spurt;therefore hand wrist radiographs have been recommended for indirect assesment of somatic maturity. However, theroutine use of hand wrist radiographs has lately been questioned from the radiation-hygiene, safety point of view. In arecent cephalometric investigation, it was found that the frontal sinus development showed a growth rhythm similar to thebody height development. Furthermore, it has been proposed that frontal sinus enlargement follows general bone growthbut little evidence has been shown. The objective of this study was to investigate the correlation between frontal sinusdepth and hand wrist maturity in Deuteromalayid group aged 7 to 17 years. A cross sectional study was conducted in 138subjects (69 males, 69 females). The frontal sinus depth and hand wrist maturation was determined using ErtÃ¼rkâ€™s andFishmanâ€™s method, respectively. The result of this study showed that there was a moderate correlation between frontalsinus depth and hand wrist maturity in males (r = 0.608) and females (r = 0.647). From this study, it can be concludedthat the usage of frontal sinus depth to substitute hand wrist maturity to assess the skeletal maturity is not appropriateenough.

Periodontal ligaments are one of the supporting tissues of teeth that undergo remodeling during the tooth movement process. Vitamin C deficiency inhibits the regeneration of collagen fibers, which are important in tissue remodeling that affects the widening of the periodontal ligament space during the process of tooth movement. The widening of periodontal ligament space can be seen by taking radiographic photos. The purpose of this study was to determine the width of the periodontal ligament space of guinea pigs by administering vitamin C, without vitamin C, and the differences between the two groups. Those samples were grouped into four groups with observation times of 1, 4, 7, and 10 days, and each group consisted of the control group and vitamin C group. Those samples were paired with orthodontic separator rubber. After the specified time was completed, periapical radiographs were taken, and the width of the periodontal ligament space was measured by using Image J software. The mean width of the periodontal ligament space in the vitamin C group was smaller than the control group. Based on this study, it can be concluded that vitamin C has an effect on reducing periodontal ligament space in the process of tooth movement. Key words: periodontal ligament space, vitamin C, tooth movement, remodeling

Different designs of ring clasp were indicated in short or long span bounded saddle. However, few researches have been done to calculate their retentive absolute forces. The purpose of this in-vitro study was to measure the retentive force of four different ring clasp designs. A test model was made from maxillary plastic replica. Second molar was seated in silicone mould then poured with dental stone. 24 cobalt-chromium ring clasp designs were fabricated to engage 0.5mm undercut using standard casting technique. They were examined radiographically for any casting defects. The dislodging force was measured for each clasp using universal testing machine. The results showed that ring clasp design 2 produced the highest retentive force, while, clasp 4 was the lowest among the other clasps. In addition, significant difference regarding the mean retentive force was estimated among designs 1, 2 and 4. The means of retentive force of ring 1, 2, 3, and 4 were equal to 17.40 Â±2.97, 17.52 Â±3.05, 12.35Â±0 .98, and 11.15Â±2.15 N, respectively. Modifying the ring clasp design by adding extra rest or fortification will change its retentive force using the same undercut depth. Each ring design provides definite retentive force. As conclusion, each ring clasps design offered specific retentive force in dry environ-ment. However design 2 presented the highest force rate while design 4 was the least retentive.

Nano tooth coloured materials may have been produced as an ideal restorative material, however, thermally induced stresses may lead to microleakage between restorative material and tooth structure which may cause unwanted complications. Thermocycling has been an important method to emulate the thermal changes of the oral cavity. This study was aimed to investigate the effect of increasing number of thermal cycles on marginal leakage of nano tooth coloured materials. A total of 56 Class V cavities was prepared on the buccal surface of the extracted single rooted human premolars and restored with either Filtek Z350 (3M-ESPE, USA) or Ceram X (Dentsply, Germany). The samples were then divided into four groups with (n=7): 1) 0 thermocycle, 2) 500 cycles, 3) 5,000 cycles and 4)10,000 cycles. All samples were immersed in 2% methylene blue dye for 4 hours at room temperature, sectioned and viewed under stereomicroscope for dye penetration. Data were analyzed using T-test and One-way ANOVA and Post-hoc Scheffe with p<0.05 considered to be significant. Microleakage was only evident in both materials at 5,000 cycles above. The results showed that there was a significant difference in microleakage between 5,000 and 10,000 cycles for both materials (Filtek Z350: p<0.001; Ceram X: p<0.001). However, there was no significant difference in microleakage between Filtek Z350 and Ceram X at 5000 cycles (p=0.194) and at 10,000 cycles (p=0.499). As conclusion, microleakage increases with the duration of thermal cycling in both nano-tooth coloured materials. Both materials showed similar pattern of microleakage when challenged to a higher number of thermal cycles.

Alcohol is used as beverage with various purposes. Drinking alcohol is supposed to be able to distress central nerve system. Saliva production is controlled by both symphatic and parasymphatic nerves. This design of study was a cross sectional. This study aimed to evaluate the effect of alcoholic drink on salivary acidity (pH) and volume. The subjects were 30 males, aged 15-35 years old, with the approval of ethical clearance from Ethic Comittee Medical Faculty of Yogyakarta Muhammadiyah University, Yogyakarta. The subjects were divided into 2 groups (alcoholic and non-alcoholic drink as control) with 15 persons, respectively. Saliva sample was collected at night. In alcoholic group, saliva was collected for 60 minutes after drinking alcohol. The subjects were instructed to gargle mineral water for 1 minute, then they were asked to stand and let the saliva flow for 3 minutes into saliva-collecting pot. Data analysis of salivary volume and pH using unpaired t-test (p<0,05). The results showed that there were significant differences in salivary volume and acidity (pH) between alcoholic and non alcoholic drink. In conclusion, drinking alcohol can decrease salivary volume and pH.

Retentive force may be increased in deeper undercuts. Three clasps were examined for this hypothesis in order to analyze the retentive force change properties for each clasp design with increasing undercut depth only. A total of 36 cobalt-chromium clasps, using half-round pattern and standard casting technique were fabricated. Three groups of clasps; Rest-Plate-Akers system, half-half, and Akers were engaged in 3 increasing undercut depths (0.25, 0.35, and 0.5 mm) on natural premolars. The test model was stone duplicate of plastic replica. Clasp retentive force was measured using universal testing machine. The results showed that the retentive forces for the tested undercuts (0.25, 0.35 and 0.5mm) were 8.59Â±1.89, 14.74Â±2.70 and 15.21Â±1.17 N for Akers; 3.06Â±0.88, 4.26Â±0.29, and 5.9Â±0.53 for half-half; and 0.9Â±0.15, 2.06Â±0.60, 2.3Â±0.50 N for Rest-Plat-Akers system respectively. Besides, the retentive force for each clasp design increased in a different way with each incremental augmentation of undercut depth. As a conclusion, changing the undercut depth altered the retentive force of the used clasp. Therefore, a clasp chosen for a definite undercut depth also can be used for deeper undercut on the same abutment when higher retentive force is required with respect to the other indication criteria.
