MANIFESTASI RONTGENOGRAFI DIABETES MELLITUS DI RONGGA MULUT

Diabetes mellitus is a common disease, described as a systemic disease of carbohydrate metabolism caused by a realtive or absolute deficiency of insulum. This condition is characterized by hyperglyecemia, glucosuria, polyuria, polydipsia, pruritis, and weight loss. Diabetes mellitus in itself does not cause periodontal disease, however diabetes or patients with an increased blood glucose concentration (>200mg/dl) tend to gave increased incidence and severity of periodontal disease. Patient with diabetics above 50 years old (3 cases) radiographically can be seen as alveolar bone loss in maxilla and mandible. Alveolar bone loss is seen larger in the posterior maxilla region. The vascular alteration in diabetics may enhance the susceptibility of periodontium to become periodontitis and serve as an etiology factor in pathologic bone resorption

Age Estimation Using Schour-Massler Method Compared to the Demirjian Method: Estimasi Usia Menggunakan Metode Schour-Massler Dibandingkan dengan Metode Demirjian

Schour-Massler and Demirjian are methods used to estimate chronological age in dental radiographs by looking at the development of permanent teeth and the maturity of the dental age. Chronological age is based on date of birth. Dental age is the age based on the maturity of the teeth. Both of these methods have been widely used in previous studies, but have never been compared. The purpose of this study was to determine whether there are differences in age estimation using the Schour-Massler and Demirjian methods. This study was an observational analytic study with a cross sectional design. The research sample was 46 patients who came to USU General Hospital at the age of 10-16 years. This research was consist at the Radiology Unit of the Faculty of Dentistry, University of North Sumatra. The results of this study indicate the p value of the Wilcoxon test results with the p value for Schour-Massler p=0.090 > 0.05 and Demirjian p=1,000. Both p values> 0.05, there is no significant difference in assessing the estimated age using both methods, so Ha is accepted. In conclusion, the Schour-Massler and Demirjian methods provide estimates of age that are close to actual age, so there is no significant difference between the two methods

Analyzing Menton Deviation in Posteroanterior Cephalogram in Early Detection of Temporomandibular Disorder

Introduction. Some clinicians believed that mandibular deviation leads to facial asymmetry and it also had a correlation with temporomandibular disorders (TMDs). Posteroanterior (PA) cephalogram was widely reported as a regular record in treating facial asymmetry and craniofacial anomalies. The objective of this study was to analyze the relationship of menton deviation in PA cephalogram with temporomandibular disorders (TMDs) symptoms. Materials and Methods. TMJ function was initially screened based on TMD-DI questionnaire. PA cephalogram of volunteer subjects with TMDs (n=37) and without TMDs (n=33) with mean age of 21.61±2.08 years was taken. The menton deviation was measured by the distance (mm) from menton point to midsagittal reference (MSR) horizontally, using software digitized measurement, and categorized as asymmetric if the value is greater than 3 mm. The prevalence and difference of menton deviation in both groups were evaluated by unpaired t-test. Result. The prevalence of symmetry group showed that 65.9% had no TMDs with mean of 1,815 ± 0,71 mm; in contrast, the prevalence of asymmetry group showed that 95.5% reported TMDs with mean of 3,159 ± 1,053 mm. There was a significant difference of menton deviation to TMDs (p=0.000) in subjects with and without TMDs. Conclusion. There was a significant relationship of menton deviation in PA cephalogram with TMDs based on TMD-DI index

Mandibular morphology of the Mongoloid race in Medan according to age groups

Background: The mandible constitutes part of the craniofacial bone that plays an important role in determining an individual’s facial profile. The mandible grows and develops throughout life from the prenatal phase up to old age when it becomes and edentulous. Changes in the mandible can be measured using radiographs. These establish several parameters of mandibular morphology, including: ramus height, condylion height, body length, condylion angle, symphysis height, symphysis width and symphysis angle. Purpose: This study aimed to determine differences in the mandibular morphology of members of the mongoloid racial group in Medan according to age as measured by cephalometric radiography. Methods: This investigation constituted analytical research using cross-sectional study with a total sample of 150 individuals divided according to age: group 1 (aged 4-12 years), group 2 (aged 13-24 years, group 3 (aged 25-34 years), group 4 (aged 35-60 years) and group of 5 (aged > 60 years). The parameters were computerized by means of a digital cephalometric radiograph, the resulting data being analized with Oneway ANOVA and LSD. Results: The mean value of the highest to the lowest ramus height, and symphysis height from the five age groups, sequentially, were in group 3, group 4, group 5, group 2, and group 1. The mean value from the highest to the lowest of body length, condylion height, condylion angle, and symphysis width, sequentially, were in group 3, group 4, group 2, group 5, and group 1. The mean value from the highest to the lowest of symphysis angle, sequentially, were in group 1, group 3, group 4, group 2, and  group 5. Conclusion: The mandibular morphology of each age group differs in Mongoloid races in Medan based on lateral cephalometric radiography in which changes are may be affected by the state of teeth and age

ANALYSIS OF ROOT CANAL MORPHOLOGY OF INCISOR TEETH USING PERIAPICAL RADIOGRAPHY BISECTING TECHNIQUE AND CHANGE HORIZONTAL ANGULATION 30º IN SUB RACE PROTO AND DEUTRO MALAY: ANALISIS MORFOLOGI SALURAN AKAR GIGI INSISIVUS MENGGUNAKAN RADIOGRAFI PERIAPIKAL TEKNIK BISEKTRIS DAN PERUBAHAN ANGULASI HORIZONTAL 30º PADA SUB RAS PROTO DAN DEUTRO – MELAYU

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 30º. 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

Special Investigation of Developmental of Mandibular Asymmetry and Imbalance Body Posture: A Literature Review

BACKGROUND: Previous studies have reported comprehensive visions about the correlation between the development of dentofacial problems and postural disorder. Mostly of dentofacial issues related to mandibular asymmetry, which can lead to erroneous treatment plans that end in frustration for both patient and orthodontist. AIM: This paper aims to describe some evidence bases dentistry of malocclusions with asymmetry in mandibular and trunk. METHODS: We used different electronic databases such as PubMed Health and Google Scholar with specific keywords such as development mandibular asymmetry, trunk asymmetry, and body posture asymmetry. In this preliminary study, the term of imbalance body posture leads to trunk and body posture asymmetry. RESULTS: Most of the studies reported the involvement of temporomandibular disorder in those asymmetries. We assumed the necessity for considering development asymmetry in an examination and should be regarded as a particular investigation procedure in orthodontic treatment. CONCLUSION: However, the limitation in understanding the developmental asymmetries in determining the etiology and risk factor of development mandibular asymmetry and imbalanced body posture require special investigation

Vertical Mandibular and Trunk Symmetry in Indonesian Orthodontic Patients

Objective: To analyze differences in vertical mandibular and trunk symmetry in orthodontic patients. Material and Methods: This was a cross-sectional study of 129 growing orthodontic patients who sought orthodontic treatment at the Dental Hospital Universitas Sumatera Utara, Indonesia. Mandibular symmetry index was observed with pre-treatment panoramic radiography based on Kjellberg's technique and trunk symmetry was evaluated based on questionnaires and visual observation. Vertical mandibular asymmetry was decided if the index of asymmetry was lower than 93.7%. The bivariate analysis used the chi-squared and Fisher's exact tests, with a significance level of 5%. Results: There was a significant association between vertical mandibular and trunk symmetry (p<0.05). The prevalence odds ratio for the association with vertical mandibular asymmetry was 3.007 (95% CI = 1.016-8.905) for trunk asymmetry. Conclusion: The necessity to consider trunk symmetry could be included in orthodontics treatment of any malocclusion with vertical mandibular asymmetry that might require a multidisciplinary approach in the future
