    This comparative cross-sectional study assessed the facial surface dimensions of a group of Malay children with unilateral cleft lip and palate (UCLP) and compared them with a control group. 30 Malay children with UCLP aged 8-10 years and 30 unaffected age-matched children were voluntarily recruited from the Orthodontic Specialist Clinic in Hospital Universiti Sains Malaysia (HUSM). For the cleft group, lip and palate were repaired and assessment was performed prior to alveolar bone grafting and orthodontic treatment. The investigation was carried out using 3D digital stereophotogrammetry. 23 variables and two ratios were compared three-dimensionally between both groups. Statistically significant dimensional differences (P<0.05) were found between the UCLP Malay group and the control group mainly in the nasolabial region. These include increased alar base and alar base root width, shorter upper lip length, and increased nose base/mouth width ratio in the UCLP group. There were significant differences between the facial surface morphology of UCLP Malay children and control subjects. Particular surgical procedures performed during primary surgeries may contribute to these differences and negatively affect the surgical outcome.

    INTRODUCTION: Cleft lip and palate (CL/P) are among the most common congenital abnormalities. The purpose of the present study was to review the literature relating to the quality of life (QoL) in young patients with cleft lip and/or palate (CL/P) and to identify the specific aspect of QoL in young patients with CL/P that is mostly affected. Other associated variables within studies that may have an impact on QoL were also identified.

    MATERIALS AND METHODS: Systematic searches of PubMed, Scopus and Web of Science databases were conducted. Independent reviewers screened the title, abstract and full texts according to predetermined inclusion and exclusion criteria. Articles published in English from January 2012 to March 2022 reporting the QoL of non-syndromic young patients aged 7-18 years with CL/P were included. Review articles and articles reporting the psychological adjustment of parents or other family members with CL/P were excluded.

    RESULTS: 975 publications were identified, of which 20 studies met our inclusion criteria. The majority of studies reported that the CL/P condition has a negative impact on the QoL. Psychological health, functional well-being, socialemotional well-being and school environment are domains that are affected. Compared with typically developing young patients, those with CL/P had lower QoL scores even though QoL was assessed using different instruments across studies. The impact of CL/P on overall QoL scores varied by age but not gender or cleft type.

    CONCLUSION: Our reviews had shown the presence of CL/P negatively affects the QoL of young patients. Psychological health is the most affected QoL domain. Understanding the impacted domain will help in planning and delivering better health care for individuals with CL/P and reducing the stigma commonly associated with CL/P. Future studies should target intervention on psychological health and consider resilience factors towards positive adjustment.

    OBJECTIVES: This study is to evaluate the dental arch relationship and palatal morphology of unilateral cleft lip and palate patients by using EUROCRAN index, and to assess the factors that affect them using multivariate statistical analysis.

    METHOD: A total of one hundred and seven patients from age five to twelve years old with non-syndromic unilateral cleft lip and palate were included in the study. These patients have received cheiloplasty and one stage palatoplasty surgery but yet to receive alveolar bone grafting procedure. Five assessors trained in the use of the EUROCRAN index underwent calibration exercise and ranked the dental arch relationships and palatal morphology of the patients' study models. For intra-rater agreement, the examiners scored the models twice, with two weeks interval in between sessions. Variable factors of the patients were collected and they included gender, site, type and, family history of unilateral cleft lip and palate; absence of lateral incisor on cleft side, cheiloplasty and palatoplasty technique used. Associations between various factors and dental arch relationships were assessed using logistic regression analysis.

    RESULT: Dental arch relationship among unilateral cleft lip and palate in local population had relatively worse scoring than other parts of the world. Crude logistics regression analysis did not demonstrate any significant associations among the various socio-demographic factors, cheiloplasty and palatoplasty techniques used with the dental arch relationship outcome.

    CONCLUSIONS: This study has limitations that might have affected the results, example: having multiple operators performing the surgeries and the inability to access the influence of underlying genetic predisposed cranio-facial variability. These may have substantial influence on the treatment outcome. The factors that can affect unilateral cleft lip and palate treatment outcome is multifactorial in nature and remained controversial in general.

    Objective To test the reliability of the modified Huddart-Bodenham (MHB) numerical scoring system and its agreement with the GOSLON Yardstick categorization for assessing the dental arch relationships in unilateral cleft lip and palate (UCLP) cases. Design A retrospective study. Setting Faculty of Dentistry, The University of Hong Kong. Patients Forty-one nonsyndromic UCLP consecutive patients attending the Joint Cleft Lip/Palate Clinic at Faculty of Dentistry in the University of Hong Kong were selected. Interventions Study models at 8 to 10 years old (T1) and 10 to 12 years old (T2) were obtained from each patient. Main Outcome Measures Models were rated with the MHB scoring system and GOSLON Yardstick index. The intra- and interexaminer reliabilities as well as correlation of both scoring systems were evaluated. Furthermore, to investigate the outcome measurements consistency, the MHB scoring system and GOSLON Yardstick were independently used to compare the dental arch relationships from T1 to T2, with the samples split into intervention and nonintervention groups. Results The MHB scoring system presented good intra- and interexaminer agreement, which were comparable to those of the GOSLON Yardstick. The correlation between the MHB scoring system and GOSLON Yardstick scores was good. Both scoring systems showed similar results when assessing the change in the dental arch relationships from T1 to T2. Conclusions The MHB scoring system can be used as an alternative method to the commonly used GOSLON Yardstick for assessing dental deformities in UCLP patients. Both scoring systems showed similar results in assessing the improvement in dental arch relationships.

    During primary cleft lip repair, a small triangular flap of about 2mm is sometimes required to achieve better symmetry of Cupid's bow. The aim of this study was to evaluate the symmetry of Cupid's bow, with and without the use of a small triangular skin flap (STSF). Forty-five children who underwent the repair of unilateral cleft lip between January 1999 and December 2000 were recruited. Twenty children had a STSF included in the repair (STSF group) an d 25 children underwent the same repair without the STSF (NSTSF group). Vermillion height was measured on the cleft and non-cleft sides using reference points. The t-test was used to compare the vermillion height ratio between the two groups. The mean age at surgery was 4±1.3months in the STSF group and 4.3±0.6years in the NSTSF group. There was no significant difference in vermillion height ratio at 5 years of age between the patients in the two groups. Thus, there is no difference in vermillion height ratio with or without a STSF in cleft lip repair. The use of a small triangular skin flap needs to be assessed carefully, as it will create an unsightly scar over the philtrum area.

    Malaysia’s palm oil industry is growing in complexity and successively to succeed on the global level by accounts for about 36% of the word production of palm oil [1]. But, Occupational Health and Safety (OHS) issues are still problematic areas that need to be addressed by all parties concerned in this industry. In the olden days, unlike construction or manufacturing industry, palm oil industry was green in OHS management system. However, due to stringent in the legislative enforcement in the past few years, it has lead some of the plantation companies to develop OHS management system, which are based on Occupational Health and Safety Assessment Series (OHSAS), towards corporate sustainability. Sustainability is not about paying lip-service to the latest corporate buzzword; neither is it about superficially meeting minimum requirements for the sake of compliance. Rather, sustainability is a core value that lies at the heart of the companies’ business conduct. In practical terms, this means strive to operate with due consideration for the interest of all stakeholders by making the health and safety of all workers a priority. This paper describes the certification of OHSAS 18001 and MS 1722 in Genting Plantations Berhad (GENP) prove the commitment to sustainability by forming guiding principle on safety management. Further, this paper also demonstrates that the implementation of safety management can help to reduce the accident rate, especially fatal accident.

    Denture esthetics as defined by Glossary of prosthodontics terms the effect produced by a dental prosthesis that affects the beauty and attractiveness of the person. [1] Removable partial dentures (RPDs) are the widely accepted and treatment of choice for most cases as it is both effective and affordable. Partially edentulous treatment planning includes both esthetics and masticatory function. A prosthesis that is highly esthetic will improve patient's motivation and acceptance. It is a very wrong notion to expect that patients will tolerate unesthetic partial dentures because good masticatory capability has been achieved. Esthetics plays a vital role in the success of partial dentures, and the length and mobility of the patient's lips play a significant role in achieving it. [2] Patients with short lips or highly mobile lips pose problems as esthetics are compromised because most clasp arms, denture borders, and other components will show when the patient smiles or speaks. [3] RPDs can easily look artificial; hence, special emphasis should aim toward restoring function, phonetics, esthetics with a long-term benefits which requires meticulous attention during fabrication. This case reports is an esthetic clasp designed for a cast partial denture for a young girl for esthetic and function.

    This paper is a preliminary report on a strategy to perform open tip rhinoplasty at the time of lip repair in bilateral cleft lip and palate deformity. This method was devised to suit unique socio-economic circumstances in the Malaysian centre of Alor Setar. Of 8 cases having surgery in 1991, 7 returned for follow-up with results being documented photographically. It is concluded that this aggressive approach is justified in severe bilateral cleft lip and palate deformity because of the cost effectiveness of limiting the number of interventions. Furthermore, it provides optimally orientated nasal tip anatomy and reduces the social stigma of cleft lip nose appearance from the earliest possible time in the child's development.

    Thalassaemia is a public health problem in Malaysia. It is known to cause skeletal deformity. The purpose of this study was to compare the skeletal, dentoalveolar, and soft tissue features of Malay transfusion-dependent thalassaemia (TDT) patients with a Malay control group. Lateral cephalometric radiographs of 30 Malay (14 males and 16 females aged 6.4-21.8 years) TDT patients and 60 normal Malays matched for chronological age and gender were analysed and compared using an independent t-test. The TDT group showed a similar sagittal relationship to the control group but with a significantly increased (P < 0.01) mandibular plane inclination. They also showed a significantly shorter (P ≤ 0.001) mandibular body, ramus length, and posterior face height and consequently a smaller ratio of posterior to anterior face height (P < 0.01). The upper and lower lips were significantly procumbent (P < 0.001) in the TDT group together with a significantly smaller nasolabial angle (P < 0.05). Dentoalveolar measurements showed less proclined maxillary teeth in the TDT group compared with the controls (P < 0.05). The cephalometric features of Malay TDT patients were characterized by a mild Class II skeletal pattern, prominent vertical growth direction of the mandible, and protruded upper and lower lips.

    Anthropometric analysis provides the most reliable comparison of the body forms by using specific landmarks determined in respect of anatomical prominences. The knowledge of unique shape, anatomy and dimensions of the nose is very useful for surgeon undertaking its repair and reconstruction. Prosthetic rehabilitation also requires the ability to imagine the position and dimension of the nose within the facial proximity. Therefore, the access to nasal data for each
    population are advantageous. The aims were to measure parameters of external nose of a Malay population and to determine the significant difference in nose value parameters between gender and age group. The direct anthropometric measurements were carried out in 86 Malay subjects within the age range of 18 to 55 years old who attended UiTM dental clinic. Nasal landmarks were
    identified, and the nose parameters were measured using digital calliper. The values were expressed as mean, standard deviation and range. Nasal height, width and length of the nasal bridge were higher in male. The intercanthal width and philtrum length were statistically not significant for both genders. There were significant differences in nasal width, philtrum length, intercanthal width and outer intercommisural mouth width between the three age groups. However, the height of the nose, length of the nasal bridge and nasal index between age group were statistically not significant. The male population and the 41-55 years age group have higher nose value parameters. The most common type of nose was platyrrhine: broad. This study also suggested that Malay population have medium broad nose as the nasal index for both genders was ≤ 84.90.

    AIM: To assess occlusal outcomes of orthodontic treatment for patients with complete cleft lip and palate.

    DESIGN: Retrospective assessment using the Peer Assessment Rating (PAR) index.

    SETTING: Consecutive patients treated by one consultant orthodontist at a tertiary care cleft center.

    PARTICIPANTS: One hundred twenty-seven patients with either complete unilateral cleft lip and palate (UCLP) or bilateral cleft lip and palate (BCLP) consecutively treated with fixed appliances.

    INTERVENTION: Fixed orthodontic appliance treatment and orthognathic surgery when required.

    OUTCOMES: The PAR index assessment was carried out by a calibrated-independent assessor. Treatment duration, the number of patient visits, and data on dental anomalies were drawn from patient records and radiographs.

    RESULTS: One hundred two patients' study models were assessed after exclusions. Mean start PAR score for UCLP (n = 71) was 43.9 (95% CI, 41.2-46.6, SD 11.5), with a mean score reduction of 84.3% (95% CI, 81.9-86.7, SD 10.1). The UCLP mean treatment time was 23.7 months with 20.1 appointments. Mean start PAR score for BCLP (n = 31) was 43.4 (95% CI, 39.2-47.6, SD 11.4), with a mean score reduction of 80.9% (95% CI, 76.3-85.5, SD 12.5). The BCLP mean treatment time was 27.8 months with 20.5 appointments.

    CONCLUSION: These results compare well with other outcome reports, including those for patients without a cleft, and reflect the standard of care provided by an experienced cleft orthodontist. As with high-volume surgeons, orthodontic treatment for this high need group is favorable when provided by a high-volume orthodontist. These findings may be used for comparative audit with similar units providing cleft care.

    Anticorrosion potential of mangrove tannins on aluminium alloys AA6061 in NaCl solution has been studied using potentiodynamic polarisation method and scanning electron microscopy (SEM). The study was carried out in different pH of corrosive medium in the absence and presence of various concentrations of tannin. The corrosion inhibition behaviour of the mangrove tannin on AA6061 aluminium alloy corrosion was found to be dependant on the pH of NaCl solution. Our results showed that the inhibition efficiency increased with increasing tannins concentration in chloride solution at pH 6. Treatment of aluminium alloy 6061 with all concentrations of mangrove tannins reduced the current density, thus decreased the corrosion rate. Tannins behaved as mixed inhibitors at pH 6 and reduction in current density predominantly affected in cathodic reaction. Meanwhile, at pH 12, addition of tannins shifted the corrosion potential to more cathodic potentials and a passivating effect was observed in anodic potentials. SEM studies have shown that the addition of tannins in chloride solution at pH 12 reduced the surface degradation and the formation of pits.

    The objective of this study is to report the occurrence, demographic and clinical findings of lip mucoceles in children. A restrospective study was conducted at the paediatric dental clinic situated at Hospital Sultanah Aminah, Johor Bahru. The period of study was 3 years beginning 2003 to 2005. Out of 1407 new cases seen over the period of study 17 (1.2%) patients presented with lip mucoceles. All lesions occurred in the lower lip. There was no sex or racial predilection. The average duration of the lesion prior to seeking treatment was 2.8 ± 2.8 months. Most patients (76.5%) first saw a medical practitioner for the problem. No spontaneous resolution of the lesions in any of the patients was noted. The preferred method of treatment of lower lip mucoceles in children is surgical excision of the involved minor salivary glands. Salivary gland mucoceles in children predominantly involve the lower lip and can be treated successfully by complete removal of the involved and associated minor salivary glands.

    AIM: The high incidence rates for oral cancer (excluding lip) are especially found in the South and South-East Asia. Therefore, the aim of the present study was to investigate the relationship between sex, age, site, and metastasis of a large sample with oral squamous cell carcinoma (OSCC).

    METHODS: A total of 989 OSCC treated with neck dissection were selected. All the relevant data were recorded from biopsy request forms. The patients were divided into seven groups, and there were nine different oral sites.

    RESULTS: The male-to-female ratio of the sample was 4:1. Most of the patients were aged between 30 and 60 years. Of the 989 patients, approximately 40% patients had metastasis. Age <30 years showed a higher probability of metastasis compared to higher age groups, but it was not statistically significant. Palate cancers had more than 14 times higher chance of metastasis, followed by maxilla (4.6 times) and tongue (2.8 times).

    CONCLUSION: The present study provides important information on the metastatic potential of OSCC in different oral sites, and identifies high-risk age groups for metastasis. This will be helpful in planning neck treatment for OSCC.
