Penprapa Chiewcharat Abstract Postgraduate Student of Orthodontic Objective: The aims of this study were to determine pre- and posttreat Residency Training Programme Department of , ment of cephalometric measurements in the skeletal anterior open bite Faculty of , Mahidol University patients with and without mini-implant anchorages (MIAs), and to compare Suwannee Luppanapornlarp the measurements between both groups. The hypothesis is that there B.Sc., D.D.S., M.Sc. (Orthodontics), are differences of treatment changes between groups. A.B.O., Tha.B.O., Ph.D. (Dental Sciences) Assistant Professor, Materials and methods: A retrospective study was performed in fifteen Department of Orthodontics, skeletal anterior open bite patients. The MIAs were used to intrude molars Faculty of Dentistry, Mahidol University in six patients (mean age of 25±8.1 years). Another nine patients (mean Supatchai Boonpratham age of 24.3 2.6 years) were treated without MIAs and served as a D.D.S., Ph.D. (Dental Sciences) ± Department of Orthodontics, control group. Paired t-test and Mann-Whitney U test were used to Faculty of Dentistry, Mahidol University determine changes within and between groups, respectively (P<0.05). Pongstorn Putongkam Results: There were no significant differences of skeletal and soft tissue D.D.S., M.Sc., Dip. Thai Board profile changes between the 2 groups, except LL-E plane. For dental (Orthodontics) Department of Orthodontics, changes, both groups show successful open bite correction with significant Faculty of Dentistry, Mahidol University treatment changes of U1-NA, overbite, overjet (P<0.05). It was found that the upper first molars in the MIAs group were more intruded significantly when compared with the control group (P<0.05). Upper incisors in the control group seem to be more extruded but not significantly. Conclusion: Molar intrusion using MIAs could be another choice of treatment for skeletal anterior open bite patients with minimal patient cooperation.

Abstract Tawepong Arayapisit Objective: Canine index is used as a sex determination in forensic DDS Department of Anatomy, odontology by comparing the individual canine index with standard canine Faculty of Dentistry, Mahidol University index calculating from the local population. However, the standard canine Wanida Sripairojthikoon index in Thai population is not well established. This report was aimed to Ph.D. (Cell Biology & Anatomy) study on sex identity based on the standard canine index and evaluate its Department of Anatomy, Faculty of Dentistry, Mahidol University accuracy in a group of Thais Akkarin Panusatid Materials and methods: Thai subjects, 200 males and 200 females, Dental student, aged 18-22 years old who had fully erupted, caries-free, normal and Faculty of Dentistry, Mahidol University non-worn upper as well as lower anterior teeth with correct dental alignment Naiwinit Somsuktaweekoon Dental student, were selected. Male and female subjects were randomly allocated into Faculty of Dentistry, Mahidol University 2 groups each. Canine widths and intercanine widths in both jaws were Pongstit Bundit measured using digital vernier calipers. Data from the first group Dental student, (100 males and 100 females) were used to calculate standard canine Faculty of Dentistry, Mahidol University Nipit Supajarupan index according to Rao et al. Data of another group (100 males and Dental student, 100 females) was used to assess the accuracy of the previously estab- Faculty of Dentistry, Mahidol University lished standard canine index. Descriptive statistical data were obtained and the potential of sexual dimorphism of the canine and intercanine widths were analyzed by t-test (α=.05). Results: Canine widths and intercanine widths of males were significantly greater than those of female (p<.001). The standard canine indices calculated with upper right, upper left, lower right and lower left canines were 0.216, 0.214, 0.257 and 0.250, respectively. The respective index values showed accuracy for sex determination at 53.5%, 60.0%, 61.5% Correspondence author: and 67.0% Tawepong Arayapisit Conclusion: It was plausible that the canine index from left mandibular Department of Anatomy, canine, in particular, could be applied as an additional method for sex Faculty of Dentistry, Mahidol University. 6 Yothi Street, Rachathewi, identity in Thai population.

Preparation of Manuscripts (effective from Volume 27 Number 1 2007)

1. Manuscripts must not be folded. One original and four copies of the manuscript as well as three copies of illustrations and tables must be submitted along with a submission form for consideration for publication via a registered mail to protect against loss. Each copy of the manuscript should be clipped, not stapled. The manuscript should be 10-20 pages including illustrations and tables of no more than 10 pages. The manuscript must be double-spaced on one-sided portrait A4 paper with an equal margin of 2.5 centimeters at all sides and paginated with the number on the top right corner. The manuscript file must be operated on Microsoft Word with the Cordia New 16 font. 2. The Thai spelling must conform to the Dictionary of the Royal Academy (1999 edition). English technical terms must be translated into Thai with the original words provided in parentheses only the first time they appear. Words that have been coined by the Royal Academy must be used. Words that have not been coined must be transliterated in accordance with the criteria for transliteration set by the Royal Academy with the original words parenthesized for their first time use. (See www.royin.go.th for more information.) Only Arabic notation can be used in the manuscript. 3. Units of length, weight, volume, etc. should be given in metric measures. A measurement of temperatures must be in Celsius. Pressure must be in mercury millimeter. A hematologic measurement and a measurement of clinical chemistry should also be in metric unit. Other measurements should follow the universal standard. Only standard abbreviations and symbols must be employed. No abbreviations should appear in the title or abstract. When an abbreviation is used, its full form should be provided after its first use in the text, with an exception of units of measurement. For manuscripts written in English, a tooth may be identified either by its name such as upper left canine or with FDI two-digit notations followed by its name in parenthesis the first time it is mentioned, for instance, Tooth #31 (lower left central incisor).

Manuscript Format and Structure

Part One must contain the following headings written in Thai and sequentially ordered.

1. Title: The title should be written in as much Thai as possible, be concise, and convey the main objective of the study. It must contain no abbreviations and should not exceed 100 letters in length. 2. Name of the author: Only first name and last name should be given. If there are many authors, their names should be organized according to their contributions to the research with the most important one listed first. 3. Degree of education: A maximum of two highest degrees should be provided after the author’s name in their official abbreviated forms. If the author has graduated from a university outside Thailand, the degree must be given in the language of the country from which he or she has obtained the degree. B 11

4. Address: All authors should provide the detailed address of their organization. If they are not affiliated with any institution, their clinic address must be given. 5. Corresponding author: One author must be designated as the corresponding author. The last name, position, professional affiliation, office phone, cell phone, fax, and e-mail address must be provided for the corresponding author for fast and convenient contact. 6. Research grant: If the study is financially supported, specify grant citing in a sequence name of the grant, organization awarding the grant, year the grant is awarded, and grant number (if any). 7. Received: Write the date appearing in the editor’s acknowledgement upon the receipt of the manuscript. 8. Accepted: Write the date appearing in the editor’s letter confirming the manuscript will be published. 9. Abstract: The abstract is a summary of the whole paper. However, no conclusion should be drawn from the discussion. Neither must there be any references, illustrations and tables. A tooth must be identified by its name rather than symbols. No English terminologies can be used. Instead they may be either translated or transliterated into Thai. No originals are needed. The following are to be included in the abstract: Objectives along with the hypotheses of the study must be given. Materials and Methods provide information on materials or patients employed in the study, number, type, method of the study or experiment, and statistics utilized in the study. Results present findings of the study including experimental study and statistical study (in case there is an analysis). Conclusion. 10. Key words: 3-6 key words from the abstract are to be provided in alphabetical order and separated from one another with commas (,).

Part Two presents the information from Part One written in English.

1. Title: The first letter of each word in the English title must be capitalized while the rest, except for proper names, are written in lower case letters. 2. Name of the author: Use the author’s first name followed by last name only. 3. Degree of education: Use universal abbreviated forms of degrees. 4. Address: Provide an address of every author. Add the country “Thailand” after area code. 5. Corresponding author: Give name and address of the corresponding author for later contact regarding the manuscript. 6. Research grant: Cite source of funding. 7. Received: Write the date appearing in the editor’s acknowledgement upon the receipt of the manuscript. 8. Accepted: Write the date appearing in the editor’s letter confirming the manuscript will be published. 9. Abstract: The abstract should not exceed 250 words and include objectives, materials and methods, results and conclusion. 10. Key words: There should be 3-6 key words whose meanings match the Thai key words and arranged in alphabetical order.

Part Three can be written in Thai or in English.

Headings of Part Three must not be indented. Use a new page for each heading. The headings are ordered sequentially as follows:

1. Introduction This first section introduces the whole paper by reviewing literature presenting knowledge and evidence from research as well as books or journals related to the study. In addition, the introduction provides rationale or significance, hypotheses, objectives, scope and methods of the study with references to other articles to relate the present study to the known prior knowledge. In other words, it should address reasons leading to the study and inform readers what questions the study is trying to answer. Thus, the introduction should review only pertinent literature and leave out those outside the scope and objectives of the study. Neither should it report results and conclusion of the study.

2. Materials and Methods Under this second heading, two subheadings are to be included.

2.1 Materials The material section imparts on details of the materials employed in the study citing chemical names, sources, characteristics or specifications of materials, and experimental samples of animals and patients. Experimentation involving human and animal subjects requires the presentation of relevant details, for instance, whether the samples are patients or normal persons, animal and plant types, number of samples as well as other specific characteristics such as gender, age, weight, and so on. Research involving experimental procedure on humans and animals must be conducted in full accordance with ethical principles. In this case, the author must be able to identify that the research has been conducted as such and supply evidence that it has been approved by the organization’s ethical board.

2.2 Methods The method section explains experimental methodology, observations or techniques for securing data, experimental procedures, measures of study, data collection, data analyses, and statistics utilized in the analysis of data. The explanation should be adequately detailed so as to allow for repeated experimentation.

3. Results This part presents findings obtained from experiments and analyses categorized into sections based on objectives of the study. Straightforward findings without too many numbers can be descriptively presented. Complicated findings with numerous numbers and variables should be presented using illustrations, tables, graphs, or charts with the interpretation of the findings in comparison with the suggested hypotheses. (Be careful not to reiterate the results given in the illustrations or tables in the text.)

4. Discussion Discussion can be drawn from objectives, hypotheses, and findings of the study. It can be discussed whether the present study reveals findings similar to or different from those previously presented, how they are alike or differ, and reasons for such similarities and differences in order for readers to understand and obtain novel knowledge created by the study. The author may discuss advantages and disadvantages of materials and methods employed in the study. New ideas or problems from the study can also be put forward. The author should discuss unexpected findings candidly and offers recommendations on how those findings can be of any use.

5. Conclusion The conclusion part encompasses the following: a summary of the findings of the study, a statement to show whether the findings correspond with the hypotheses, a conclusion drawn from the discussion, and suggestions for further use of the results as well as further study. B 12

6. Acknowledgements This one-paragraph section is where the author acknowledges organizations and persons who have made substantive contributions to the study. (It should be remarked, however, that citing in the acknowledgements too many organizations and persons can undermine the article as readers may assume that most of the study has been carried out with assistance from others.)

7. References References include the list of documents the author has cited in the text. References are indicated by superscript Arabic numbers right after the cited names or statements and should be numbered consecutively (for example, 1,3,6 or 1-3. They should be neither indented nor parenthesized. The same numbers must be used for repeated references. Using abstracts as references and unpublished data must be avoided. All references in the list should be numbered consecutively as they appear in the text, following the Vancouver system. Abbreviated names of journals must follow the reference style in the PubMed (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi). If a journal name does not appear in the PubMed, then the Index Medicus should be applied.

7.1 Journal references

Illustrations

1. All illustrations must be concisely titled in English and numbered in order of appearance in the text using Arabic notation. They can be drawings, photographs, diagrams or graphs. 2. Titles and legends must be typed underneath the illustrations which are submitted on separate pages. Color names, dying techniques, and magnification rates may be provided after legends or designated as bars within the illustrations. Symbols, arrows, or letters within the illustrations must be clearly identified. 3. A box must be left in the text to indicate the area where each illustration will be put and marked within the illustration “Illustration 1”, e.g., B 14

Illustration 1

4. Both color and black & white photographs can be used. As for color photographs, high-quality glossy prints of 8.9×14 cm. (postcard) are required. The title, number and author’s name should be indicated on the back of each photograph lightly in pencil so as not to leave any unwanted mark on the front. Also indicate the top edge of each photograph. All illustrations should not be adhered to anything and must be placed in a separate envelop. Digital photographs should not be embedded in the text. Instead they should be separately filed. High resolution photographs of no less than 300 dpi must be saved on a diskette or a CD-ROM. They can be in any format that can be opened using Adobe Photoshop (tiff, gps, fpg, etc.). To avoid blur and fuzz, polaroids should not be used. 5. Radiographs should not be printed directly from the x-rays as the prints may be different from their originals. Black & white prints should be obtained from copies of the original x-rays. Scans of radiographs should not be used either. 6. Line drawings, graphs or charts must be drawn or printed with explanatory ordinate and abscissa in black & white on glossy paper. 7. Prints from slides are required. 8. If all or parts of previously published illustrations are used, permissions must be obtained from the copyright holder concerned and the permissions must be indicated.

Tables 1. Each table should be typed on a separate page. A box must be left in the text to indicate the area where each table will be put and marked within table “Table 1”. 2. Tables should be numbered consecutively and should have a concise explanatory title in English written over each table. Tables should be kept to the minimum essential for proper presentation of the results. 3. Each table must be typed with the footnote explaining abbreviations, symbols, or statistical values (if any) appearing on the table. Table footnotes should not be numbered using Arabic numerals as they may be mixed up with the references. To avoid such confusions, symbols such as *, +, #, ** may be used instead. 4. Tables should contain no vertical lines, horizontal lines, and borderlines.

Review Process It is imperative that authors prepare manuscripts in accordance with the format guidelines of the Journal. The manuscripts must be checked and proofread for accuracy before being submitted to the editor. Manuscripts will be reviewed by at least two experts in the field. Review process generally takes two to eight weeks. The Journal then informs the corresponding author of the result of the review process. Manuscripts with potential for publication will be sent to the authors for revision. When all revisions and changes are made according to the referees’ comments, revised manuscripts must be submitted to the editor within a set period. Otherwise, the Journal will assume the author no longer wants to publish his or her manuscript. The Editor will notify the author when the manuscript is accepted for publication. The final version of revised manuscript must be saved on diskette or CD-ROM and submitted along with the diskette or CD-ROM. The author must keep a copy of the manuscript for later reference or confirmation. During the printing process, the Editor will send the artwork of the manuscript to the corresponding author once for proofreading and checking for academic accuracy. (If the author does not return the proofread manuscript within a set period, the Journal will assume the author no longer wants to publish his or her manuscript.) The Editor will not send the manuscript to the author for proofreading again but more proofreading will be carried out by the editorial board to enable faster printing process.
