Bolton analysis is one of the analyzes used in determining tooth size discrepancies, the ratio of size of mesiodistal teeth is very important in determining orthodontic treatment plans so that good occlusion can be achieved as a result of treatment. The aim of this study is to find out the width of mesiodistal teeth crowded with Bolton's analysis of Balinese men and women. This des-criptive research method using purposive sampling technique, used 40 models study samples of male and female from Balinese patients at the Mahasaraswati Denpasar University Dental Hospital. The largest contour of mesial to distal dimension of the tooth measured parallel to the occlusal plane. The results obtained were anterior ratios and the overall analysis of Bolton in the Balinese tribe. The anterior ratio of the Balinese men and women was obtained at 79.55%±3.40 and 61.57%±5.32. The overall ratio of Balinese men and women was obtained at 91.66%±2.57 and 102.50%±5.26. It was concluded that Bolton's anterior ra-tio and Bolton's overall ratio in crowded teeth of Balinese men and women show an average value that exceeds Bolton's ideal value, so that the location of faulty teeth of the Balinese tribe can be seen in the mandible.
ntroduction: The mandibular movement pattern was used to evaluate the presence of a dysfunction. Impaired TMJ function is called temporomandibular disorder (TMD). One of the causes that are often associated with TMD is a bad habit of chewing one side. This habit is often done without realizing it, causing an imbalance in the distribution of the chewing load and can result in deviation or displacement. The occurrence of TMD can be characterized by limited mouth opening of less than 40 mm. Objective: This study aims to determine the presence of abnormalities in the pattern of mandibular movement in the bad habit of chewing on one side. Methods: The research method used is descriptive observational research with saturated sampling technique with a sample of 25 students of the Faculty of Dentistry, Mahasaraswati University Denpasar, class of 2017. Data collection was carried out by observing through videos of mandibular movement patterns. Results and conclusions: The results showed the pattern of mandibular movement with the habit of chewing on one side, in men who deviated 28%, in women 32%, while in men who did not deviate 12% and in women as much as 28%
Introduction: one of the malocclusion’s etiology is bad habits such as mouth breathing habit. The purpose of this study was to determine the relationship between the mouth breathing habit through with the type of malocclusion. Materials and Method: the sampling method used was purposive sampling obtained from giving questionnaires to parents and clinical examination of the oral cavity of students at SDN 17 Dauh Puri Denpasar. The number of samples with mouth breathing habit were 50 samples. Classification of dentition malocclusion in students was assessed using a modified Dewey Angle Classification. Data analysis used the chi-square test. Results and Discussion: the results of this study were that the mouth breathing habit was more dominant in the Class I Angle type 2 Dewey malocclusion with a total of 25 students (50%) and in the Class I Angle type 4 Dewey malocclusion with a total of 14 students (28%). Conclusion: the conclusion of this study is that there is a significant relationship between the mouth breathing habit and the type of malocclusion.
