Dent Traumatol, 2020 Apr;36(2):185-191.
PMID: 31743570 DOI: 10.1111/edt.12529

BACKGROUND/AIMS: No previous epidemiological study has investigated the prevalence and associated factors of traumatic dental injuries (TDIs) among Libyan children. Such information is required for the planning and evaluation of health services. The aim of this study was to assess the prevalence of TDIs and associated factors among 12-year-old schoolchildren in Benghazi, Libya.
METHODS: Data for this study were collected as part of a comprehensive, cross-sectional survey investigating oral health status and treatment needs of 12-year-old schoolchildren in Benghazi, Libya, between December 2016 and May 2017. Sociodemographic information was collected through a dental health questionnaire. The children were assessed for oral health status, including TDIs according to modified World Health Organization (WHO) classification criteria, in their classroom by trained and calibrated examiners. Anthropometric measures, lip competence and overjet were all assessed and reported. History of TDIs was sought among those affected. Logistic regression models were applied for TDIs as an outcome variable. The statistical significance for all tests was ≤0.05.
RESULTS: Data from 1134 participants were included in this study. TDIs were observed in 10.3% of the sample. Most of these TDIs were enamel fractures only (55.6%) and enamel and dentine fractures (35.9%). "Falling" was the most common cause of TDIs, accounting for 51% of cases. While increased overjet appeared to be associated with higher risk of TDIs (OR: 1.92; 95% CI: 1.29-2.86), being female (OR: 0.34; 95% CI: 0.22-0.53) and overweight (OR: 0.33; 95% CI: 0.13-0.83) were also associated with lower risk of having TDIs.
CONCLUSIONS: This survey showed that a considerable proportion (10.3%) of 12-year-old Libyan children had TDIs, with relatively high unmet treatment needs. More efforts are required to develop effective prevention programmes and to enhance the provision of dental treatment of TDIs for Libyan children.

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.

In Malaysia the School Dental Service (SDS) provides comprehensive dental treatment with the aim of rendering the child dentally fit before leaving primary school at 12 years. Hence the purpose of this study was to investigate I) the prevalence and treatment needs of traumatised permanent incisors and 2) to assess their relationship to the degree of incisor overjet amongst 12-13 year-old schoolchildren. The sample comprised of 1519 schoolchildren attending 20 secondary government and government-aided schools in Klang district. There were 772 boys and 747 girls. The sampling procedure involved a multistage, clustered and stratified random sampling. The prevalence of traumatic injuries in permanent incisors was 2.6% which confirmed the results of a previous local study. Boys suffered more trauma than girls with a ratio of about 1.5:I. A majority (77.5% ) of the children had one tooth affected. The most commonly affected teeth were the upper central incisors (91.8%) followed by the lower central incisors (4.1%). A high percentage (57.5%) of children with traumatised anterior teeth had increased overjet (>3mm). Almost all cases (93.9%) required two or more surface fillings. However the majority of affected children (56%) were satisfied with their appearance. It is concluded that traumatic dental injuries should be incorporated as part of the treatment plan for the SDS and appropriately managed soon after occurrence or not later than 12 years after which they leave the SDS. Future epidemiological studies should also give due emphasis to the relative importance of traumatised teeth in children.

his study assesses inter-examiner reproducibility in recording various malocclusion parameters and Index of Orthodontic Treatment Need (IOTN) grade during patient examination by utilising the kappa statistic. Five previously calibrated orthodontists clinically examined 233 non-orthodontically treated schoolchildren aged 14-17 years for recording various malocclusion parameters. The examination was repeated twice, thirty days apart and precluded the use of study-models or radiographs. Although good inter-examiner reproducibility was observed in recording incisor class, IOTN dental health grade, type of posterior crossbite, and excellent for parameters with absolute criteria like
erupted supernumeraries, etc, substantial examiner variation resulted in only fair reproducibility for recording IOTN esthetic category, canine class, overbite category, traumatic overbite and upper centre-line shift of two millimetres or more from the facial midline. Reproducibility for detecting occlusal displacement in the presence of crossbite was poor, and kappa statistic was incalculable for recording openbite and number of upper incisors rotated 30° or more. Kappa was also incalculable for recording IOTN dental health subcategory due to the creation of asymmetric tables caused by rarely chosen subcategory options. Despite prior agreement between previously calibrated examiners on evaluation criteria, detection of certain malocclusion parameters during an epidemiological examination can prove to be challenging. Epidemiological studies that report on prevalence of malocclusion in the population should always report on the kappa reproducibility, especially if the study is carried out by multiple examiners.

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.

Sains Malaysiana, 2013;42(1):25-32.

The aims of this study were to assess the skeletal pattern and the malocclusion of Kadazan Dusun ethnic patients who seek for orthodontic treatment. Cephalometric radiographs (248) and 345 study models were collected from four orthodontic clinics in Sabah. The cephalometric mean values (SNA, SNB, ANB, MMA, SNMxP, UIMxP, LIMnP and ALFH) were measured and the study models were analysed for overjet, overbite, incisor and molar relationships. Some morphological or occlusal features such as shovel shape, Talon cusp, peg shape teeth, midline diastema, canine displacement and supernumerary tooth were also noted. The frequency and correlation of cephalometric mean values and prevalence of malocclusion were analysed using SPSS 18. Class I Skeletal pattern was the most common (48%) followed by Class II (33%) and Class III (18%). There was a strong correlation between SNA and SNB values (>0.70). Class II/1 incisor relationship has the highest frequency (41%) followed by Class III (32%), Class I (21%) and Class II/2 (6%). Class II Molar relationship of both right and left showed highest frequency (38%) followed by Class I (33%) and Class III (30%). Increased of overjet (44%) and reduced overbite (41%) and shovel-shaped incisor were the most common occlusal and dental features. The Kadazan Dusun patients who seek for orthodontic treatment in Sabah were mostly presented with Class I Skeletal pattern with high prevalence in Class II/1 incisor relationship, Class II molar relationship, increased overjet and reduced overbite. The orthodontic treatment pertaining to this ethnicity should be in line with the findings that will benefit patient specifically based on their common presented features.

Wahab RM, Idris H, Yacob H, Ariffin SH

Eur J Orthod, 2012 Apr;34(2):176-81.
PMID: 21478298 DOI: 10.1093/ejo/cjq179

This prospective study investigated the difference in clinical efficiency between Damon™ 3 self-ligating brackets (SLB) compared with Mini Diamond conventional ligating brackets (CLBs) during tooth alignment in straightwire fixed appliance therapy. Twenty-nine patients (10 males and 19 females), aged between 14 and 30 years, were randomly divided into two groups: 14 patients received the SLB and 15 received the CLB. Upper arch impressions were taken for pre-treatment records (T(0)). A transpalatal arch was soldered to both maxillary first molar bands prior to extraction of the maxillary first premolars, followed by straightwire fixed appliances (0.022 × 0.028 inch). A 0.014 inch nickel titanium (NiTi) wire was used as the levelling and aligning archwire. Four monthly reviews were undertaken and impressions of the upper arch were taken at each appointment (T(1), T(2), T(3), and T(4)). Displacements of the teeth were determined using Little's irregularity index (LII). Data were analysed using the Mann-Whitney U-test. In the aligning stage, the CLB group showed significantly faster alignment of the teeth compared with the SLB group at the T(1)-T(2) interval (P < 0.05). However, there were no differences at T(2)-T(3), and T(3)-T(4) for either group (P > 0.05). The CLB group showed 98 per cent crowding alleviation compared with 67 per cent for the SLB after 4 months of alignment and levelling. Mini Diamond brackets aligned the teeth faster than Damon™ 3 but only during the first month. There was no difference in efficacy between the two groups in the later 3 weeks. Alleviation of crowding was faster with CLB than with SLB.

Abdul Rahim FS, Mohamed AM, Nor MM, Saub R

Angle Orthod, 2014 Jul;84(4):600-6.
PMID: 24417495 DOI: 10.2319/062813-480.1

OBJECTIVE: To determine the prevalence of malocclusion and need for orthodontic treatment among persons with Down Syndrome (DS).
MATERIALS AND METHODS: Study participants were 113 persons with DS from the selected community-based rehabilitation center who fulfilled the inclusion and exclusion criteria. Ten occlusal characteristics of the Dental Aesthetic Index (DAI) were measured on study models to determine the degree of malocclusion. A single score represented the dentofacial anomalies, determined the level of severity, and determined the need for orthodontic treatment.
RESULTS: Crowding in the anterior maxillary and mandibular arch was the main malocclusion problems among the subjects with DS. Comparison between age group and genders revealed no significant differences in four categories of orthodontic treatment need (P > .05).
CONCLUSION: Most of the subjects with DS (94; 83.2%) had severe and very severe malocclusion, which indicated a desirable and mandatory need for orthodontic treatment.

Objectives:To determine the different occlusal characteristics in primary dentition of 3 to 6 year old Malay children and to create a preliminary database for future Malaysian studies as currently none of the studies has been conducted in Malaysian population regarding the occlusal features in primary dentition. Materials and method:The subjects were within the age ranging from 3 – 6 years old attending nurseries and kindergartens located within Sungai Buloh, Selangor. Sixty subjects were screened but only 47 fulfilled the criteria to be included in this study. Intra-oral examination was done to determine the terminal plane, canine relationship, overjet, overbite and primate space in the subjects. Results: Almost two thirds of the subjects (72.34%) presented with straight terminal plane. All but one subject were observed with Class I canine relationship. 61.7% subjects were with an ideal overjet and 53.19% of subjects had an ideal overbite. The mean value for primate space in the maxilla was 2.92mm and 1.60mm in the mandible. There was no significant difference between gender in all the parameters assessed. Conclusion: The results from the study shown that only few of the subjects had a tendency of malocclusion in their permanent dentition. However, a longitudinal study should be done to follow up their occlusal feature in the permanent dentition.
