    The prevalence of cleft lip and palate in human is 1 in 500 live births worldwide. Non·syndromic clefts are a complex trait with both genetic and environmental etiology. The aim ofthe study was to assess the association between maternal exposure to second-hand smoke during pregnancy and ruk of having cleft child. Unmatched case-control study was carried out among Malays in Kelantan.
    1 Case and control subjects were denned as mothers of cleft children and mothers of normal children respectively. The cleft children were recruited from the Combined Cleft Clinic at Kota Bharu Dental Clinic. Normal chiMren were selected at Orthodontic Clinic, Kota Bharu. A total of 184 cases and controb with age range from 17 to 50 years were interviewed using the standard craniofacial
    registration form. Multiple Logistic Regression modeling was used to estimate adjusted odds ratio of factors associated with non-syndromic oral cleft. Signijicant factors include history of miscarriage (OR: 3.40; 95% C1:1.05, 11 .08) p=0.042; duration of exposure to second-hand smoke for 15-30 minutes (OR: 2.41; 95% C1:1.42, 4.09) p 30 minutes (OR: 5.16; 95% C1:Z.87, 9.28) p

    Introduction: Appropriate oral health knowledge is essential to enable parents to be responsible for the oral health care of their children especially those with special needs. This study aimed to determine the oral health knowledge, attitude and practice (KAP) of parents and cariogenic food intake of their non-syndromic cleft lip with or without cleft palate children (NSCLP) compared to non-cleft children.

    Methods: A comparative cross-sectional study was conducted on randomly selected parents with children aged 1 to 6 years at Hospital Universiti Sains Malaysia and Kota Bharu Dental Clinic. A face-to-face interview using a validated questionnaire on oral health KAP and cariogenic food intake of their children was done. Data were analysed by using IBM SPSS version 22.0.

    Results: Sixty-four Malay parents with NSCLP (n=33) and non-cleft (n=31) children were recruited. The mean (SD) percentage score of oral health knowledge of parents in both groups (NSCLP and non-cleft) was fair, 59.5%(11.85) and 62.0%(15.00), P=0.4722; oral health attitude was good, 78.0% (9.30) and 80.2% (15.40), P=0.504; but oral health practice was poor 33.8% (5.94) and 36.1 (8.44), P=0.220. The cariogenic food frequency score was significantly higher in noncleft children; 40.2(10.32) compared to NSCLP children, 34.8(9.46), P=0.032.

    Conclusions: Parents of both groups had fair knowledge and good attitude but poor oral health practice. Cariogenic foods were consumed more by the non-cleft children. Oral health awareness among the parents needs to be strengthened towards good oral health attitude and practice and non-cariogenic food choices for the betterment of oral health status of their children.

    Erosion-corrosion of elbow configurations has recently been a momentous concern in hydrocarbon processing and transportation industries. The carbon steel 90° elbows are susceptible to the erosion-corrosion during the multiphase flow, peculiarly for erosive slug flows. This paper studies the erosion-corrosion performance of 90° elbows at slug flow conditions for impact with 2, 5, and 10 wt.% sand fines concentrations on AISI 1018 carbon steel exploiting quantitative and qualitative analyses. The worn surface analyses were effectuated by using laser confocal and scanning electron microscopy. The experiment was conducted under air and water slug flow containing sand fines of 50 µm average size circulated in the closed flow loop. The results manifest that with the increase of concentration level, the erosion-corrosion magnitude increases remarkably. Sand fines instigate the development of perforation sites in the form of circular, elongated, and coalescence pits at the elbow downstream and the corrosion attack is much more obvious with the increase of sand fines concentration. Another congruent finding is that cutting and pitting corrosion as the primitive causes of material degradation, the 10 wt.% sand fines concentration in carrier phase increases the erosion-corrosion rate of carbon steel up to 93% relative to the 2 wt.% sand fines concentration in slug flow.

    BACKGROUND: Nonsyndromic cleft lip and/or palate is one of the most common human birth defects worldwide that affects the lip and/or palate. The incidence of clefts varies among populations through ethnic, race, or geographical differences. The focus on Malay nonsyndromic cleft lip and/or palate (NSCL/P) is because of a scarce report on genetic study in relation to this deformity in Malaysia. We are interested to discuss about the genes that are susceptible to cause orofacial cleft formation in the family.

    METHODS: Genome-wide linkage analysis was carried out on eight large extended families of NSCL/P with the total of 91 individuals among Malay population using microarray platform. Based on linkage analyses findings, copy number variation (CNV) of LPHN2, SATB2, PVRL3, COL21A1, and TOX3 were identified in four large extended families that showed linkage evidence using quantitative polymerase chain reaction (qPCR) as for a validation purpose. Copy number calculated (CNC) for each genes were determined with Applied Biosystems CopyCallerTM Software v2.0. Normal CNC of the target sequence expected was set at two.

    RESULTS: Genome-wide linkage analysis had discovered several genes including TOX3 and COL21A1 in four different loci 4p15.2-p16.1, 6p11.2-p12.3, 14q13-q21, and 16q12.1. There was significant decreased, p

    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.

    We analyzed the facial features of Chinese children with repaired unilateral cleft lip and palate (UCLP) and compared them with a normal control group using a three-dimensional (3D) stereophotogrammetry camera. This cross-sectional study examined 3D measurements of the facial surfaces of 20 Chinese children with repaired UCLP and 40 unaffected Chinese children aged 7 to 12 years old, which were captured using the VECTRA 3D five-pod photosystem and analyzed using Mirror software. Twenty-five variables and two ratios were compared between both groups using independent t-test. Intra- and inter-observer reliability was determined using ten randomly selected images and analyzed using intra-class correlation coefficient test (ICC). The level of significance was set at p

    A 37-week gestation male boy was born to a gravida seven para six mother by spontaneous vertex delivery at home. The baby cried at birth. On day 3 of life, he was admitted for respiratory distress. Physical examination revealed ectrodactyly, thin dry skin, anomalous tear duct with cardiomegaly. X-ray revealed absent radii, cardiomegaly and hemivertebra at L1. Echocardiogram revealed perimembranous type of ventricular septal defect. A diagnosis of Ectodermal Dysplasia Ectrodactyly Clefting Syndrome with ventricular septal defect was made. He was managed conservatively in the nursery. However, he expired on day 27 of life following short spell of fever apnoeic episode due to neonatal sepsis.

    Out of 52,379 babies delivered in the Maternity Hospital, Kuala Lumpur, over a 2-year period, 64 were born with cleft lip and/or palates. The rate of occurrence of cleft was 1.24 per 1000 livebirths or 1.20 per 1000 deliveries. The Chinese babies had the highest incidence (1.9 per 1000 deliveries) while the Malays had the lowest (0.98 per 1000 deliveries). The most common type was unilateral cleft of the primary and secondary palates. Among the Indian babies, cleft of the secondary palate was most common. 18.8 percent of all the affected babies had positive family history of cleft. 10.9% of the mothers of affected babies had positive history of drug ingestion especially Chinese herbs during pregnancy. Associated congenital abnormalities occurred in 15.6% of the babies with cleft lip and/or palate.

    The aims of this study were to assess the quantitative values of measurements using proportion indices in the craniofacial region in patients with repaired, non-syndromic, complete unilateral cleft lip and palate (UCLP), and compare them with a control group who did not have clefts using the non-invasive systems of 3-dimensional technology. Three-dimensional measurements of the facial surfaces of 15 Malay patients who had UCLP repaired and 100 Malay control patients aged 18-25 years were analysed. The 3-dimensional images of the respondents' faces were captured using the VECTRA-3D Stereophotogrammetry System. Eleven craniofacial proportions were assessed using a combination of 18 linear measurements obtained from 21 anthropometric soft tissue landmarks. These measurements were used to produce proportion indices to find the differences in the morphological features between the groups, and assessed using the independent sample t test and z scores. There were significant differences between the groups in 7 out of 11 craniofacial proportion indices (p=0.001-0.044). Z scores of 2 indices were disproportionate. They were nasal index (which was severely supernormal) and upper lip index (which was moderately supernormal). Patients with UCLP had higher mean z scores, indicating that patients with UCLP tended to have larger faces than the control group. There were clinically important differences mainly in the nasolabial area, where the nose and the upper lip were wider, larger, or flatter in patients with UCLP.

    We have evaluated the craniofacial morphology of Japanese patients with unilateral cleft lip and palate (UCLP) and assessed the various postnatal factors that affect it. Lateral cephalograms of 140 subjects (mean (SD) aged 7 (2) years) with UCLP were taken before orthodontic treatment. Surgeons from Hokkaido University Hospital had done the primary operations. The craniofacial morphology was assessed by angular and linear cephalometric measurements. Cheiloplasty, palatoplasty, and preoperative orthopaedic treatment were chosen as postnatal factors. To compare the assessments of the postnatal factors, we made angular and linear cephalometric measurements for each subject and converted them into Z scores in relation to the mean (SD) of the two variables. Subjects treated by the modified Millard cheiloplasty had larger sella-nasion-point A (SNA) and nasion-point A-pogonion (NA-POG) measurements than subjects treated by the modified Millard with a vomer flap cheiloplasty. Two-stage palatoplasty showed consistently better craniofacial morphology than the other palatoplasty. Subjects who had preoperative orthopaedic treatment with a Hotz plate had significantly larger upper incisor/sella-nasion (U1-SN) measurements than who had no preoperative orthopaedic treatment or an active plate. We conclude that in subjects treated by a modified Millard type of cheiloplasty, a two-stage palatoplasty, and a Hotz plate there were fewer adverse effects on craniofacial morphology.

    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.

    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.

    OBJECTIVE: The aim of the systematic review is to evaluate the effects of gingivoperiosteoplasty (GPP) on alveolar bone quality and facial growth in patients with cleft lip and palate (CLP).

    SEARCH METHODS: Electronic and manual search was done up to October 2017.

    ELIGIBILITY CRITERIA: Clinical and observational studies that compared GPP to control; patients without GPP evaluated either before or after the age for secondary bone graft (SBG).

    DATA COLLECTION AND ANALYSIS: Studies selection was done by 2 authors independently. Risk ratio and mean difference with 95% confidence intervals (CIs) were calculated using random-effects models.

    RESULTS: Thirteen articles were included in the review. All studies were at high risk of bias. Poorer alveolar bone quality was found in the GPP group compared to the SBG group. The pooled data showed a statistically significant increase in the incidence of Bergland type III in the GPP group compared to SBG (risk ratio: 11.51, 95% CI: 3.39-35.15). As for facial growth, GPP group resulted in a more retruded maxillary position (as indicated by "Sella-Nasion-Subspinale" angle [SNA value]) compared to control group by -1.36 (CI: -4.21 to 1.49) and -1.66 (CI: -2.48 to -0.84) when evaluated at 5 and 10 years, respectively. The protocol for presurgical infant orthopedics used in conjunction with the GPP procedure might have affected the results of the alveolar bone and facial growth outcomes.

    CONCLUSIONS: Definitive conclusions about the effectiveness of GPP cannot be drawn. Very weak evidence indicated that GPP might not be an efficient method for alveolar bone reconstruction for patients with unilateral and bilateral CLP. Gingivoperiosteoplasty surgery could lead to maxillary growth inhibition in patients with CLP.

    OBJECTIVE: To determine the prevalence of mutations in transforming growth factor beta 3 (TGFβ3) and Jagged2 genes and their association with nonsyndromic cleft lip with or without cleft palate (CL±P) patients.

    DESIGN: Cross-sectional study on nonsyndromic CL±P and noncleft patients.

    SETTING: Reconstructive clinic and outpatient dental clinic, Hospital Universiti Sains Malaysia.

    PATIENTS: Blood samples of 96 nonsyndromic CL±P and 96 noncleft subjects.

    MAIN OUTCOME MEASURE: Prevalence and association of mutations in TGFβ3 and Jagged2 genes with nonsyndromic CL±P.

    RESULTS: Most of the nonsyndromic CL±P patients (53.1%) had left unilateral CLP. There were slightly more females (56.6%) compared with males. The prevalence of the mutations in the TGFβ3 gene was 17.7% (95% confidence interval [CI]: 9.5, 24.5) and in the Jagged2 gene was 12.5% (95% CI: 5.5, 18.5), which was higher compared with the noncleft group. For the TGFβ3 gene, there was no mutation in the coding region in either of the groups. All variants were single nucleotide polymorphisms located within the intronic flanking region. Two variants were identified (g.15812T>G and g.15966A>G) in both nonsyndromic CL±P and noncleft patients. However, the association was not significant (P > .05). Three variants (g.19779C>T, g.19547G>A, and g.19712C>T) were identified in the Jagged2 gene among nonsyndromic CL±P and noncleft patients. Only g.19712C>T showed a significant association with nonsyndromic CL±P patients (P = .039).

    CONCLUSION: g.19712C>T might play a crucial role in the development of cleft lip and palate. To the best of our knowledge, this is the first report of the mutation found within intron 13 of the Jagged2 gene among nonsyndromic CL±P Malay patients.

    OBJECTIVES: Determination of the psychosocial status and assessment of the level of satisfaction in Malaysian cleft palate patients and their parents.
    DESIGN: Cross-sectional study.
    PARTICIPANTS AND METHODS: Sixty cleft lip and palate patients (12 to 17 years of age) from Hospital Universiti Sains Malaysia and their parents were selected. The questionnaires used were the Child Interview Schedule, the Parents Interview Schedule, and the Cleft Evaluation Profile (CEP), administered via individual interviews.
    RESULTS: Patients were teased because of their clefts and felt their self-confidence was affected by the cleft condition. They were frequently teased about cleft-related features such as speech, teeth, and lip appearance. Parents also reported that their children were being teased because of their clefts and that their children's self-confidence was affected by the clefts. Both showed a significant level of satisfaction with the treatment provided by the cleft team. There was no significant difference between the responses of the patients and their parents. The features that were found to be most important for the patients and their parents, in decreasing order of priority, were teeth, nose, lips, and speech.
    CONCLUSIONS: Cleft lip and/or palate patients were teased because of their clefts, and it affected their self-confidence. The Cleft Evaluation Profile is a reliable and useful tool to assess patients' level of satisfaction with treatment received for cleft lip and/or palate and can identify the types of cleft-related features that are most important for the patients.
