    Forensic odontological examination of a disputed bitemark can furnish the police and the prosecutor with useful evidence to either implicate or exonerate a person in relation to a crime, on the basis that each person’s bitemark is as distinctive as his or her dentition. The aims of this article are (a) to evaluate the extent of which bitemark evidence is reliable as a proof of identification of a biter for the purposes of criminal investigation and prosecution in Malaysia and (b) to make the necessary recommendations (if any) for the purpose of improving the reliability of such evidence. Where a questioned bitemark is not sufficiently detailed, any findings made from its examination shall be highly unreliable and prejudicial. On the other hand, where a bitemark is sufficiently detailed, then any findings made from its examination may be reliable, provided that the forensic odontologists and other practitioners in the criminal justice system are professionally trained to handle the said bitemark. Therefore, police officers must be given a basic training in the field of forensic odontology so that they will be able to appreciate the evidential value of bitemark and contribute to the development of bitemark cases in Malaysia. The relevant authorities governing the dental practice in Malaysia should standardize the methodology and terminology used in bitemark examination and in the reporting of its findings so that confusion and inconsistency among the forensic odontologists are kept absolutely low. Finally, forensic odontologists must be given specialized training in bitemark examination so that the probative value of their findings can be improved.

    AIM: The aim of the study was to assess the reliability and validity of cephalometric variables from MicroScribe-3DXL.

    MATERIALS AND METHODS: Seven cephalometric variables (facial angle, ANB, maxillary depth, U1/FH, FMA, IMPA, FMIA) were measured by a dentist in 60 Malay subjects (30 males and 30 females) with class I occlusion and balanced face. Two standard images were taken for each subject with conventional cephalometric radiography and MicroScribe-3DXL. All the images were traced and analysed. SPSS version 2.0 was used for statistical analysis with P-value was set at P<0.05.

    RESULTS: The results revealed a significant statistic difference in four measurements (U1/FH, FMA, IMPA, FMIA) with P-value range (0.00 to 0.03). The difference in the measurements was considered clinically acceptable. The overall reliability of MicroScribe-3DXL was 92.7% and its validity was 91.8%.

    CONCLUSION: The MicroScribe-3DXL is reliable and valid to most of the cephalometric variables with the advantages of saving time and cost. This is a promising device to assist in diverse areas in dental practice and research.

    The case reported here highlights the importance of examination of functional occlusion along with static occlusion. Any undetected malocclusion during early mixed dentition has potency to alter the growth and function of stomatognathic system. Premature contacts in primary canine region is the most prevalent cause of functional mandibular shift and can lead to TMJ problems for the prevalence of self correction of such malocclusion is very low if not intervened. A case of functional mandibular shift due to faulty canine guidance because of premature contacts is discussed here. Selective grinding of premature contacts and myofunctional exercise resulted in well balanced centric occlusion coinciding with centric relation.

    This survey outlines the proportion of the various features of occlusion in the permanent dentition of the three ethnic races, Chinese, Malay and Indian in Malaysia. The mean age of the high school children surveyed was 16.4 years. The Chinese and Malays had almost similar distribution of the different types of occlusion. There was a significantly higher prevalence of Class III occlusion among the Chinese and Malays as compared to the Indians. In addition, an edge to edge incisor relationship seemed to be a norm in the Chinese (54%) and Malays (50%) whilst the overjet of between 2-4 mm and the overbite of between 1/3 to 2/3 was more normal to Indians (50%). A crowded dentition was also a norm for the three races.

    A late adolescent patient presented with a Class III malocclusion on a skeletal Class III base, complicated by severe upper arch and moderate lower arch crowding, reverse overjet, anterior and bilateral posterior crossbites with displacement, proclined upper incisors, retroclined lower incisors, distally tipped lower canines and non-coincident centrelines. Treatment was undertaken on an extraction basis by employing the use of an upper removable appliance with Z-springs and posterior bite blocks to correct the anterior crossbite, quad helix and jockey arch for arch expansion, and pre-adjusted edgewise fixed appliance to level and align, space closure and achieve a mutually protective functional occlusion. This paper discussed the rational and evidences behind the treatment employed.

    Epidemiological studies of occlusion and malocclusion not only help in orthodontic treatment planning and evaluation of dental health services but also offer a valid research tool for ascertaining the operation of distinct environmental and genetic factors in the aetiology of malocclusion. The objective of this article was to give an overview on occlusion, malocclusion and the various methods on measuring the occlusion. Each index and method of the assessment described was based on the opinion of an individual or a group of individuals. It had been widely agreed that no particular index or method available that are truly inclusive of all occlusal criteria. Therefore, different indices or method had been developed according to different requirements and it may be necessary to use more than one index in order to gather information to suit the objective of the particular study.

    Objectives: To assess the occlusal features, tongue habits, lip competence and their gender dimorphism in 12 years old Malaysian Malay school-children.

    Materials and methods: The method involved cl inical examination of 208 subjects from public schools in Shah Alam, Selangor, Malaysia. Occlusal status was assessed according to Angle classification. The following features were also assessed and recorded: overjet, overbite, traumatic overbite, crowding, spacing, midline diastema, cross bite, scissors bite, dental midline shifts, canine displacement, missing teeth, traumatically fractured teeth, tongue thrust and lip competence. Descriptive statistics were used for all measurements; Chi-square was used to assess gender differences.

    Results: Class I malocclusion is most prevalent in boys and girls (44.0% and 43.8% respectively), followed by Class Ill malocclusion (31% in boys and 30 .4% in girls). Anterior crowding was found in 69.7% of the sample while anterior spacing was found in 30.8%. Incompetent lips were more common in boys than gir1s.

    Conclusions: The prevalence of malocclusion in this age group may warrant the need for more preventive and interceptive measures in dental and oral health planning.

    INTRODUCTION: The maxillomandibular relationship (MMR) record is a critical step to establish the new occlusion in implant supported complete mouth rehabilitation. Using patients existing denture for recording the MMR requires implant definitive cast to be modified extensively to completely seat the denture (with unaltered flanges) on it. This may influence the correct seating of the denture on the implant definitive cast causing faulty recording of the MMR.
    MATERIALS AND METHOD: Elastomeric record bases, reinforced with the resin framework, are fabricated and relined with the light body elastomeric material when all the healing abutments are in place. The MMR is recorded with these elastomeric record bases using vacuum formed facial surface index of the occluded existing dentures as a guideline.
    RESULTS: The elastomeric record bases with facial surface index of the existing dentures can allow clinicians to record MMR records without removing the healing abutments from the mouth with acceptable accuracy. This can save chair-side time of the procedure. The record of facial surfaces of existing complete denture in the form of vacuum formed sheet helps to set the occlusal vertical dimension.
    CONCLUSION: Use of facial surface index together with the elastomeric record bases can be the useful alternative technique to record the MMR in patients with implant supported full mouth rehabilitation. Further study is required to prove its routine clinical utility.

    Backgrounds: People in Yemen and in East African countries chew khat more than five hours daily.

    Objectives: The aim of this study was to assess the relationship between khat and occlusal caries progression.

    Methods: A cohort study was carried out among 98 Yemeni khat chewers and 101 non-chewers aged 18-35 years old with early occlusal caries lesions. All participants answered questions on socio-demographic, khat , oral hygiene , sugar intake, and oral health knowledge at baseline. All posterior teeth with an early enamel lesion on occlusal surfaces detected by visual inspection at baseline were also subjected to DIAGNOdent assessment to confirm early lesion (DIAGNOdent reading 13-24). Participants were re-examined after 12 weeks. Caries progression was considered to occur when the DIAGNOdent reading was >25. Data were analyzed using Relative risk, Mann-Whitney U test, a Wilcoxon Signed-Rank test and logistic regression analysis.

    Results: Occlusal caries progression incidence between khat chewers and non-chewers, with the relative risk was 1.68. There was no significant difference in occlusal caries progression on chewing side and non-chewing side among khat chewers. Khat chewing was a statistical predictor for those with low income.

    Conclusion: Khat is a risk factor for occlusion caries progression among low income group.

    OBJECTIVE: Considering that the available studies on prevalence of malocclusions are local or national-based, this study aimed to pool data to determine the distribution of malocclusion traits worldwide in mixed and permanent dentitions.

    METHODS: An electronic search was conducted using PubMed, Embase and Google Scholar search engines, to retrieve data on malocclusion prevalence for both mixed and permanent dentitions, up to December 2016.

    RESULTS: Out of 2,977 retrieved studies, 53 were included. In permanent dentition, the global distributions of Class I, Class II, and Class III malocclusion were 74.7% [31 - 97%], 19.56% [2 - 63%] and 5.93% [1 - 20%], respectively. In mixed dentition, the distributions of these malocclusions were 73% [40 - 96%], 23% [2 - 58%] and 4% [0.7 - 13%]. Regarding vertical malocclusions, the observed deep overbite and open bite were 21.98% and 4.93%, respectively. Posterior crossbite affected 9.39% of the sample. Africans showed the highest prevalence of Class I and open bite in permanent dentition (89% and 8%, respectively), and in mixed dentition (93% and 10%, respectively), while Caucasians showed the highest prevalence of Class II in permanent dentition (23%) and mixed dentition (26%). Class III malocclusion in mixed dentition was highly prevalent among Mongoloids.

    CONCLUSION: Worldwide, in mixed and permanent dentitions, Angle Class I malocclusion is more prevalent than Class II, specifically among Africans; the least prevalent was Class III, although higher among Mongoloids in mixed dentition. In vertical dimension, open bite was highest among Mongoloids in mixed dentition. Posterior crossbite was more prevalent in permanent dentition in Europe.

    Pathologic tooth migration (PTM) is a common complication following moderate to severe chronic periodontitis, which lead to the undesirable consequences such as traumatic occlusion and impaired aesthetic appearance. Multidisciplinary approach had been successfully used in overcoming the problem. However, since periodontal tissue support is reduced in PTM, further migration of teeth may occur as they were always subjected to the external forces such as occlusion and soft tissue pressure during function. This case report described a 41 year-old male with a further migration of his upper right central incisor after periodontal therapy. After multidisciplinary approach was carried out to overcome the problem and the tooth was on stable condition, permanent splinting was placed to secure the tooth.

    OBJECTIVES: The aim of this study is to assess the treatment outcome of complete unilateral cleft lip and palate (CUCLP) patients using modified Huddart/Bodenham scoring system (MHB). To determine whether there is an association of congenital and postnatal factors with the treatment outcome.

    DESIGN: Retrospective observational study.

    SETTING: Two regional cleft-referral centers.

    MAIN OUTCOME MEASURES: In the current study, 101 pairs of dental models of non-syndromic CUCLP patients were retrieved from hospital archives. Each occlusal relationship from central incisor till the first permanent molars were scored except the lateral incisor. Sum of 10 occlusal relationships in each study sample gave a total occlusion score. The primary outcome was the mean total occlusion score.

    RESULTS: According to MHB, a mean (standard deviation) total occlusion score of -8.92 (6.89) was determined. Based on treatment outcome, 66 cases were favorable (grades 1, 2, and 3) and 35 cases were unfavorable (grades 4 and 5). Chi-square tests indicated, difference of cheiloplasty ( P = .001) and palatoplasty ( P < .001) statistically significant. Five variables-gender, family history of cleft, cleft side, cheiloplasty, and palatoplasty-were analyzed with a logistic regression model.

    CONCLUSIONS: Final model indicated that cases treated with modified Millard technique (cheiloplasty) and Veau-Wardill-Kilner method (palatoplasty) had higher odds of unfavorable treatment outcome.

    The aim of this study was to evaluate the relationships of selected facial measurements with mesio-distal crown widths and dental arch dimensions in individuals with normal occlusions. A cross-sectional study was conducted on 276 subjects with Angle's Class I normal occlusions. Three-dimensional images of the face and dental casts were captured and analyzed using stereophotogrammetric systems. Significant correlations were found between the sagittal facial variables and both upper and lower dental arch dimensions and to lesser degree with the horizontal and vertical variables. The values of correlation coefficients calculated between facial and dental crown measurements ranged from .01 to .50 for upper teeth and .01 to .49 for lower teeth. The values of correlation coefficients between facial and upper dental arch dimensions ranged from .01 to .55 and those between facial and lower dental arch dimensions ranged from .01 to .60. A principal components analysis showed that the sagittal dimensions, face height, nose, labial fissure, binocular widths were positively associated with dental arch dimensions and mesio-distal crown diameters in males. On the other hand, only the sagittal variables were associated with dental dimensions in females. The results of this study confirm that positive associations exist between facial and dental arch dimensions. These relationships should be taken into consideration when attempts are made to modify dental arch size as part of orthodontic treatment. Moreover, these relationships are also relevant to prosthodontists involved with selecting tooth sizes that display optimal functional balance with the craniofacial structures.

    The purpose of this report is to introduce Cu-sil like denture as a functional space maintainer. Here, we report two paediatric cases treated with Cu-sil like denture with multiple edentulous spaces and partially erupted/compromised permanent teeth. Cu-sil like denture not only serves as removable partial functional space maintainer, but also restores the vertical dimension of occlusion, mastication and aesthetics in children. Cu-sil like denture is used in elderly patients who are not willing for extraction of remaining few healthy teeth in the oral cavity. This concept utilizes the remaining natural teeth in the arch, accommodates them within the denture through perforations made in the denture base. The gap between the denture base and the tooth is sealed using a resilient liner. Such denture is used for the paediatric age group in this report for functional rehabilitation temporarily. The report describes the pros and cons of the Cu-sil like denture use in children with technique of preparation along with review of literature.

    Discrepancies between tooth sizes can cause orthodontic problems such as crowding and improper occlusion. By identifying these problems, better orthodontic treatment outcome can be achieved. The aim of this study is to identify anterior tooth size discrepancies among 4 different types of malocclusion i.e. Class I; Class II division 1 (II/1); Class II division 2 (II/2); and Class III. Methods: A retrospective study was carried out using 200 orthodontic study models where 50 study models were taken for each of the 4 malocclusion groups. The samples were selected using random sampling technique based on the orthodontic waiting list in the Orthodontic Department, Dental Faculty, UKM. All anterior teeth were measured by the same examiner at the largest mesio-distal dimension, using a digital caliper recorded up to 0.01 mm. Comparison between the 4 groups of malocclusion were made intra-arch using individual tooth size measurement and inter-arch using Anterior Bolton Index (ABI). Results: For the intra-arch assessment, Class II/1 had significantly the largest upper and lower anterior tooth size except for its upper canine and lower central incisor. Class III group had insignificantly the smallest mandibular anterior teeth compared to other malocclusion groups. For inter-arch assessment, Anterior Bolton Index (ABI) of all samples was 79.2 ± 3.94%. The highest ABI was noted in Class II / 2 of 80.3 ± 4.71%. However, no significant differences were found among the 4 malocclusion groups (p>0.05). Conclusion: Most of the anterior teeth in Class II division 1 were the largest of all. No significant difference in the inter-arch tooth size discrepancies were detected among all malocclusion
    groups.
