Authentic Leadership In Illness Blogs: What We Can Learn From Jaw Surgery Bloggers, Marilyn Mitchell
Authentic Leadership In Illness Blogs: What We Can Learn From Jaw Surgery Bloggers, Marilyn Mitchell
Marilyn Mitchell
This paper argues that authentic leadership theory provides a useful model for explaining the communication of orthognathic or jaw surgery bloggers. Previous studies concluded that illness blogs can empower patients, but no research considered any leadership theory as a model for blogging. For this study, 24 publicly available blogs were analyzed to find expressions that demonstrated each of the four components of authentic leadership, which are self-awareness, relational transparency, communication based upon an internalized moral perspective, and balanced processing of information. The research also analyzed blog comments to find expressions that demonstrated followers’ development of the positive psychological capacities of …
Evaluation Of The Occlusion And Maxillary Dental Arch Dimensions In The Mixed Dentitions Of Yemeni Population, Ahmed A. Madfa
Evaluation Of The Occlusion And Maxillary Dental Arch Dimensions In The Mixed Dentitions Of Yemeni Population, Ahmed A. Madfa
Ahmed A. Madfa
Determination the dental arch dimensions in human populations is necessary for various fields of dental sciences. This study was designed to evaluate the maxillary dental arch dimensions of Yemeni children aged (10-12) years. The sample was gathered from primary and intermediate school in Sana'a city, Yemen. Clinical examination was performed on 200 subjects (100 males and 100 females) that fulfillment the criteria of this study. The examination was carried out for subjects that have either normal occlusion or class I with anterior dental crowding. Pairs of studying models for the dental arch was constructed and evaluated by special software for …

Objective: To determine and compare the frequency distribution of various arch shapes in ethnic Malays and Malaysian Aborigines in Peninsular Malaysia and to investigate the morphological diff erences of arch form between these two ethnic groups. Methods: We examined 120 ethnic Malay study models (60 maxillary, 60 mandibular) and 129 Malaysian Aboriginal study models (66 maxillary, 63 mandibular). We marked 18 buccal tips and incisor line angles on each model, and digitized them using 2-dimensional coordinate system. Dental arches were classified as square, ovoid, or tapered by printing the scanned images and superimposing Orthoform arch templates on them. Results: Th …
Comparison Of Tooth Size Discrepancy Of Three Main Ethnics In Malaysia With Bolton's Ratio, Rahman A. N. A. A., Othman S. A.

The objective of this study was to investigate the applicability of Bolton's ratios in orthodontic population of Malaysian main ethnics; Malay, Chinese and Indians. Ninety convenient samples consisting of 30 pre-orthodontic study casts from each ethnic that fits the inclusion criteria were selected. The greatest mesiodistal widths of each tooth from six to six for overall ratio and three to three for anterior ratio were measured using a digital callipers linked to Hamilton Arch Tooth System software to the nearest 0.01mm. Means of the ratios were calculated using Bolton analysis. One sample t-test statistic analysis was carried out to compare …

The objective of this retrospective study was to investigate what percentage of the dental students in the University of Malaya has a tooth size discrepancy. The sample comprised 40 good quality pre-treatment study models with fully erupted and complete permanent dentitions from first molar to first molar, which were selected from the dental students of the University of Malaya. The mesiodistal diameter tooth sizes were randomly measured manually from first molar to first molar using digital calliper (Mitutoyu) accurate to 0.01 mm, and the Bolton analyses for anterior and overall ratios were calculated by scientific calculator. Reproducibility analysis for intra- …

The purpose of this study was to validate the use of digital dental study casts obtained from Cone beam CT Scan (CBCT) against gold standard; that is traditional dental study cast measured with digital caliper. Thirty-four study casts of Malaysian Aborigines were selected from Centre of Malaysian Pribumi Studies Databank. Palatal depth of each study casts were measured using Mitutoyo digital caliper. Subsequently, all the study models were scanned using i-CAT CBCT and the palatal depth were measured using i-CAT software. Data were analysed using SPSS version 12.0 where Intraclass correlation and paired T-test were employed. There was no significant …

Objective: To explore how many millimeters of tooth size discrepancy (TSD) are clinically significant, to determine what percentage of a representative orthodontic population has such a tooth size discrepancy, and to determine the ability of simple visual inspection to detect such a discrepancy. Materials and Methods: The sample comprised 150 pretreatment study casts with fully erupted and complete permanent dentitions from first molar to first molar, which were selected randomly from 1100 consecutively treated white orthodontic patients. The mesiodistal diameter tooth sizes were measured using digital calipers, and the Bolton analysis and the tooth size corrections were calculated by the …

OBJECTIVE: To determine and compare the reproducibility and speed of two methods of performing Bolton's tooth-size analysis. DESIGN: Analysis of randomly selected clinical sample. SETTING: Bristol Dental Hospital, University of Bristol, United Kingdom. MATERIALS AND METHODS: Pre-treatment study casts of 150 patients were selected randomly from 1100 consecutively treated Caucasian orthodontic patients. Bolton tooth-size discrepancies and ratios were measured using two methods; one method employed entirely manual measurement and the Odontorule slide rule, while the other employed digital calipers and the HATS analysis software. Twenty study casts were measured twice, a week apart with both methods. Another three investigators also …

OBJECTIVES: To review the literature on Bolton's tooth-size discrepancies (TSD) with specific attention to the prevalence of TSD, and the possible influence of different classes of malocclusion, gender and racial group. Also examined were the validity of the standard deviations from Bolton's samples as an indicator of significant TSD, methods of measurement of TSD and their reproducibility. Based on the review, suggestions are made as to how future work could be improved. RESULTS AND CONCLUSIONS: Studies have reported from 20 to 30% of people with significant tooth-size anterior discrepancies and 5-14% for overall TSD. Bolton's original sample was appropriate for …

Siti Adibah Othman
A case report of a 13-year old male presented in his mixed dentition stage with a Class II division 2 incisor relationship on a mild Class II skeletal base, complicated by an increased overbite, retroclined upper and lower incisors (bimaxillary retroclination) and moderate crowding in the upper and lower labial segments. Treatment was undertaken without extraction employing an upper removable appliance with a flat anterior bite plane to correct the overbite, and an anterior screw to proclined the upper incisors while waiting for the eruption of the permanent teeth. Pre-adjusted edgewise fixed appliances were placed in the lower arch, then …
