Fulltext Is Khat chewing habit a risk factor for occlusal caries progression?

Al-Alimi KR, Razak AAA, Saub R

Afr Health Sci, 2018 Dec;18(4):1036-1045.
PMID: 30766570 DOI: 10.4314/ahs.v18i4.25

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.

MyJurnal

A pilot study was conducted on 135 sixteen-year-old students from three rural schools in Kelantan to establish the prevalence of orofacial pain and discomfort. About 44% reported to have experienced some oro-facial pain in the preceding four weeks. About 27% of those with pain, still experienced the pain at the time of clinical examination but only 8% have consulted professional help. Most of the pain encountered were only mild or moderate in nature. Only 7% and 10% respectively, reported that the pain affected their sleep and concentration to study. The main cause was toothache and sensitivity. The prevalence of discomfort was 22%, the most common causes being recurrent oral ulcers and bleeding gums. The impacts of orofacial pain was mainly manifested at the personal level, and very few affecting social functioning. However, untreated decay and missing teeth were very low (mean DT 0.47, mean MT 0.27), while filled teeth (mean Ff 2.9) was the main component of the DMFf (mean 3.66, sd ± 2.6). Severe periodontal disease and the prevalence of traumatised teeth was not a major public health problem. The high prevalence of pain merit further research. Therefore a larger study involving other age-groups in other states is planned.

The purpose of this study was to gather information on the oral hygiene behaviour among the visually impaired adolescents. Interview and observation methods were used to collect data. A total of 114 visually impaired adolescents were interviewed and 10 of the interviewees were selected for observation on the actual oral hygiene practices. The mean age of the sample was 16 years old. The sample comprised of 53.5% female, majority were Malays (86.8%) and most of them were from the lower income group. Fifty four percent of the sample had low vision and 45.6% were blind. All of the participants reported that they brushed their teeth daily and most of them brushed twice a day or more. Flossing (6.1%) was not common practice among this group. It was observed that they encountered some difficulties, especially when putting the toothpaste on the toothbrush and also the way that they brushed their teeth could cause detrimental effect to the oral cavity. Thus, they need to be taught on proper oral hygiene care so that they can practice safe oral hygiene care and maintain their own oral health.
Fulltext Toothpastes Available In The Malaysian Market

Saub, R.

Ann Dent, 1998;5(1):-.
MyJurnal

This study was undertaken to investigate the number and types (fluoride or non-fluoride) of toothpaste products available in the Malaysian market based on the label. Thirty-five brands of toothpaste were identified, of which ten (29%) were specifically recommended for children. Two of the children's toothpaste recommended that children below seven years old use a pea size amount of toothpaste. One (3%) was recommended for both children and adult. The remaining 24 (69%) did not state if they were recommended for either children or adults. To improve the flavour of the toothpastes, a variety of flavours had been added especially in children's toothpaste. Almost half of the toothpastes were for prevention of tooth decay and gum disease. Other indications were for tooth sensitivity, tooth whitening and stain removal. Twentyseven (77%) of the toothpastes were imported, while eight (23%) were made in Malaysia. Twenty-six (74%) of the toothpaste contained fluoride and the most common type of fluoride used was sodium monofluorophosphate (NaMFP). The fluoride concentration was not labeled in more than half (63%) of the fluoridated toothpaste. Of those that were fluoridated, different units of measurement were used. As there is no uniformity in the labelling of these products, it is recommended that the responsible authorities should take more action in enforcing proper labelling of the fluoride concentration in the toothpaste using standardized units.

MyJurnal

The aims of this study were to determine the prevalence and factors that influenced smoking behaviours among male adolescents in Kuantan, Pahang. A cross-sectional study was conducted among the form four male students in Kuantan District. Three hundred and twenty three students were randomly selected from eight secondary schools. A self-administered questionnaire was distributed to all the respondents. Almost half of the sample was smokers (45.8%) and half of them were Malays (53.1%). Students whose parents had lower level of occupation were more likely to smoke (58.8%). Among smokers, 34.5% of them smoked since primary school and a majority (91.7%) smoked 10 or less cigarettes per day. Half of them (53.4%) reported that they bought loose cigarettes and most of them used their school pocket money to purchase the cigarettes (81.7%). From the multivariate analysis, it was found that Non-Science Stream classes (OR=3.92, 95% CI= 2.10, 7.32), peers' smoking (OR=6.07, 95% CI= 2.32, 15.92), and attitude towards smoking (OR= 21.93, 95% CI= 9.71,49.51) were significantly associated with smoking habit. The prevalence of smoking among male adolescents was considerably high'in this population. It is recommended that antismoking activities in school be carried out regularly and should involve an active participation from the adolescents themselves since peers have great influence on smoking habits.

MyJurnal

The aim of the present study is to determine the “community indicator” for dental caries among secondary school children within the Federal Territory of Kuala Lumpur (FTKL). School factors were investigated for their ability to be used as community indicators. The components encompassing school factors include: type of school, school’s examination performances at the Peperiksaan Menengah Rendah (PMR) level, in the subjects of Mathematics, Bahasa Melayu (Malay Language), Science and English, school’s socioeconomic circumstances and school’s material deprivation. The study design is ecological in nature where schools were the unit of analysis. It used aggregated data for caries experiences acquired from the Oral Health Management Information System and the school factors which were extracted from the schools’ database. The subjects involved in this study were all the (75) day type secondary schools in FTKL. However, only 55 schools had complete information both for the dental caries factor and the school factors which were available for analysis. The use of bivariate analysis suggested that the school mean DMFT was significantly associated with the schools’ performance in English (p= 0.02) and the schools’ socioeconomic code (p= 0.005). The schools’ performance in English and socioeconomic code were able to explain about 10 percent and 14 percent of the variation in the school mean DMFT respectively. The final model that included both variables together explained about 17 percent of the variation in school mean DMFT. As a conclusion, this study suggests that the schools’ performance in English at the PMR level and the schools’ socioeconomic code could be used as community indicator to identify secondary schools with higher caries level in FTKL. Nevertheless, further
improvement of the model is needed in order to create a more reliable indicator.

MyJurnal

To assess the oral health related quality of life
(OHQoL) of a selected population of Malaysian adults and to compare the OHQoL by periodontal status. Material & Methods: This cross-sectional study comprises a convenient sampling of fifty subjects from the Primary Care Unit, Faculty of Dentistry, University of Malaya. OHQoL was assessed using the Malaysian version of Oral Health Impact Profile-14 (OHIP-14). Basic periodontal examination (BPE) was performed on all subjects to determine their periodontal status. Descriptive statistics and bivariate analysis were performed.
Results: Psychological discomfort, physical pain and psychological disability domains were the most affected dimensions in this population. Subjects with income levels >RM2,500 had higher impacts on their OHQoL as compared to those from other income levels (p0.05).
Conclusion: Subjects with high income levels had high impacts on their OHQoL. Those with periodontitis experienced higher impacts on their OHQoL as compared to those who had a healthy periodontium or gingivitis and affected a wide range of domains of quality of life.

MyJurnal

A cross-sectional study was conducted to ascertain the relationship between parental oral health perception on the importance of the deciduous dentition and the dental caries status of their preschool children. Clinical oral examination of the preschool children was performed and self-administered questionnaires were given to the parents to be completed. Four hundred and eight preschool children were examined and 390 of their parents responded to the self-administered questionnaire. Those parents who brought their children for regular dental check-up at least once a year; favoured restorative treatment and practised tooth brushing habit before bedtime were more likely to have children with significantly lower mean 'dft' as well as higher proportions of caries free mouth (> 50 %). Those children who started early in practising tooth brushing also had better dental caries status but the differences were not significant. However, there were no significant and appreciable differences in their mean 'dft' with respect to the frequencies of tooth brushing per day. It was concluded that parents with better oral health perception as reflected by those parents who (a) practiced regular dental check-up for their children; (b) favoured restorative treatment for their children's decayed deciduous teeth; (c) ensured their children brushed their teeth before bedtime are associated with better dental caries status of their preschool children.
Fulltext The Betel Quid Chewing Habit: Why It Should Be Stopped And What Can Be Done To Stop This Habit?

Saub, R.

Ann Dent, 2001;8(1):-.
MyJurnal

The habit of chewing betel quid has been practised since ancient times. Although the world has gone through modernization, a significant proportion of people still practices this habit. Substantial evidence has shown that betel quid chewing is associated with the occurrence of oral cancer and precancerous lesions, which has a tremendous psychosocial impact on an individual's life. Thus it becomes significantly important to dentistry to look into this matter. Since betel quid chewing is one of the causes of oral cancer, effort in cha~ging this habit is essential. This article addresses this issue.

MyJurnal

Objective: This study aimed to assess the awareness of periodontal disease and level of knowledge of the relationship between smoking and periodontal disease amongst subjects who were smokers verses non-smokers.
Methods: A questionnaire looking at knowledge of respondents regarding gum disease and knowledge and awareness about oral impacts of smoking on periodontal disease was developed and pretested in Dental Faculty University of Malaya. Basic Periodontal Examination (BPE) index was used to assess periodontal status.
Results: The questionnaire was answered by 130 subjects. Prevalence of smoking was 14.6%. A total of 58.6% non-smokers and 57.9% smokers knew about periodontal disease. However, only 26.1% non-smokers and 10.5% smokers knew that the cause for periodontal disease was plaque. More non-smokers than smokers knew that smoking affected periodontal health (80.2% and 68.4% respectively) (p>0.05) and tooth mobility was an effect of smoking on periodontal health (27.0% and 0%) (p<0.05). Regarding source of information on effect of smoking on periodontal health, 63.2% smokers and 63.1% non-smokers reported obtaining information through the mass media. However, only 31.6% smokers and 28.8% non-smokers were informed by their dentist.
Conclusion: The awareness of periodontal disease and knowledge of the relationship between smoking and periodontal disease was low in this selected population of smokers and non-smokers.

MyJurnal

To explore the association between social
support and stress levels in preclinical and clinical dental
students in Malaysia. Method: A cross sectional survey
of dental undergraduate students was conducted at the
Faculty of Dentistry, University of Malaya, Universiti
Kebangsaan Malaysia and Universiti Sains Malaysia.
Stress was measured using the Dental Environment Stress
(DES) questionnaire. A DES-32 item was used to measure
stress for the clinical students and DES-16 item for the
preclinical students. Four questions were used to measure
social support. The total stress scores were standardized
for comparison purposes. Results: A total of 357 (79.7%)
preclinical and 417 (71.8%) clinical undergraduate dental
students responded to the questionnaires. The clinical
students experienced higher stress [mean standardized
DES score = 72.63, SD = 10.64] than preclinical students
[mean standardized DES score = 70.19, SD=12.01]. The
two most stressful items reported by preclinical students
were “fear of failing” and “examination and grades”.
Among clinical students, the two most stressful items related
to academic were “completing course requirement” and
“fear of failing course” and items related to clinical session
were “fear of being barred due to the clinical schedule”
and “patients late or absent”. Multiple regression analyses
revealed that low stress levels among preclinical students
were significantly associated to a lot of contact with
students of the same course. Conclusion: To some extent,
social support does play a role in explaining differences in
perceived stress, in particular among preclinical students.
Correlation between numbers of cells in human dental pulp and age: Implications for age estimation

Hossain MZ, Daud S, Nambiar P, Razak FA, Ab-Murat N, Saub R, et al.

Arch Oral Biol, 2017 Aug;80:51-55.
PMID: 28371626 DOI: 10.1016/j.archoralbio.2017.03.018

OBJECTIVE: The aim of this study was to investigate correlations between dental pulp cell count of odontoblasts, subodontoblasts and fibroblasts and age, within different age groups. Formulation of regression equations using the dental pulp cell count for predicting age was attempted.
DESIGN: Eighty-one extracted teeth were grouped into two age groups (6-25 years, 26-80 years). The teeth were demineralized and histological sections were prepared for cell count. Regression equations were generated from regression analysis of cell count and tested for age estimation.
RESULTS: The number of dental pulp cells were found to increase until around the third decade of life and following this, the odontoblasts and subodontoblasts cell numbers began to decline while the fibroblasts seemed to remain almost stationary. The Pearson correlation test revealed a significant positive correlation between the cell number for all type of cells and age in the 6-25 years group (r=+0.791 for odontoblasts, r=+0.600 for subodontoblasts and r=+0.680 for fibroblasts). In the 26-80 years age group, a significant negative correlation of the odontoblasts (r=-0.777) and subodontoblasts (r=-0.715) with age was observed but for fibroblasts, the correlation value was negligible (r=-0.165). Regression equations generated using odontoblasts and subodontoblasts cell number were applicable for age estimation. The standard error of estimates (SEEs) were around±5years for 6-25 years and±8years for 26-80 years age groups. The mean values of the estimated and chronological ages were not significantly different.
CONCLUSIONS: A significant correlation between the cell count of odontoblasts and subodontoblasts with age was demonstrated. Regression equations using odontoblasts and subodontoblasts cell number can be used to predict age with some limitations.

Aust Dent J, 2001 Sep;46(3):198-202.
PMID: 11695159

BACKGROUND: The purpose of this study was to determine the oral health status and treatment needs of elderly hostel residents in Melbourne.
METHOD: One hundred and seventy-five subjects aged 65+ were selected from 20 hostels within a 10 km radius of Melbourne's central business district.
RESULTS: Subjects were clinically examined and interviewed using a standard questionnaire. In the course of the clinical examination, coronal caries, root caries, periodontal disease, denture status and related treatment needs were assessed. The mean age of the subjects was 83.7, the majority of whom were female (80 per cent). About 35 per cent of the sample were dentate. The mean number of teeth present among dentate persons was 13.8, the mean coronal caries experience was 24.9 DMFT and mean root caries was 2.3 R-DF. Of the dentate subjects, 46 per cent required at least one restoration for coronal caries and 30 per cent required at least one restoration for root caries. Most dentate subjects had calculus and none had deep pockets, therefore, indications for periodontal treatment did not include complex care. More than 50 per cent of lower full dentures were retained unsatisfactorily and about half of the total number of subjects required prosthetic treatment.
CONCLUSIONS: Although there was a high number of treatment needs, most requirements involved simple technologies that could be delivered by auxiliaries.
Dentinal tubules occluded by bioactive glass-containing toothpaste exhibit high resistance toward acidic soft drink challenge

Bakri MM, Hossain MZ, Razak FA, Saqina ZH, Misroni AA, Ab-Murat N, et al.

Aust Dent J, 2017 Jun;62(2):186-191.
PMID: 27813093 DOI: 10.1111/adj.12484

BACKGROUND: Dentine hypersensitivity is a common problem attributed by patent dentinal tubules. Ingredients incorporated in toothpastes aim to occlude patent dentinal tubules to minimize the dentine hypersensitivity. However, frequent consumption of acidic soft drinks may reverse the dentinal tubules' occlusion. In this in vitro study, the efficacy of dentinal tubules occluded by commercially available toothpastes to withstand different durations of an acidic soft drink challenge was investigated.
METHODS: One hundred and twenty dentine discs were divided into three groups. The discs from each group were brushed with toothpaste containing bioactive glass, arginine and control toothpaste. Each group was then divided into four subgroups and exposed to acidic soft drink over four different time durations.
RESULTS: The scoring and the percentage of occluded dentinal tubules by Novamin-containing toothpaste was significantly better compared with arginine or the control toothpaste. Acidic soft drink challenge reduced the extent of dentinal tubules occlusion along with time. Dentinal tubules occluded by Novamin-containing toothpaste withstand the acidic challenge comparatively for a longer period.
CONCLUSIONS: The findings demonstrated that occlusion of dentinal tubules is more efficient by the bioactive glass-containing toothpaste and thus may contribute to its better resistance to acidic soft drink challenge.

PMID: 26419358 DOI: 10.1186/s12903-015-0098-3

Chronic periodontitis (CP) is a global public health issue. Studies have suggested CP could be linked to obesity due to their similar pathophysiological pathway. The aim of this study is to determine the prevalence of CP and to assess the predictors for CP among the obese Malaysian population.
METHODS: This is a cross-sectional study on obese participants. Obesity is defined as an individual who has Body Mass Index (BMI) ≥ 27.5 kg/m(2). A convenience sampling method was used. A total of 165 paricipants were recruited. This study involved answering questionnaires, obtaining biometric and clinical measurements of Visible plaque index (VPI), Gingival bleeding index (GBI), Probing pocket depth (PPD) and Clinical attachment loss (CAL). Data analysis was carried out using SPSS statistical software (SPSS Inc., version 20, US).
RESULTS: A total of 165 participants; 67 (40.6%) males and 98 (59.4%) females participated in the study. Mean age of the participants was 43.9 (± 8.9). The prevalence of CP among the obese population was found to be 73.9%. Out of this, 43 and 55% were categorised as moderate and severe CP respectively. Around 64% of participants had sites with CAL ≥ 4 mm and participants with sites with PPD ≥ 4 mm were reported to be 25%. Around 83% of the participants had sites with GBI ≥ 30 and 92% of participants had sites with VPI ≥ 20%. GBI and VPI were found to have significantly higher odds for CP.
CONCLUSION: Prevalence of CP was high among obese Malaysians. GBI and VPI were potential predictors for CP in this obese population.

PMID: 33789646 DOI: 10.1186/s12903-021-01540-0

BACKGROUND: The influence of scaler tip design on root surface roughness, tooth substance loss and patients' pain perception is investigated.
METHODS: This article was divided into the following parts: Part 1 Surface roughness and substance loss: an in vitro study, which involves intact extracted teeth sectioned and treated using a piezoelectric ultrasonic device (PM200 EMS Piezon, Switzerland) with a conventional scaler tip (FS-407) and a Perio Slim (PS) scaler tip (Perio Slim DS-016A). All sectioned samples for tooth surface roughness (n = 20) and tooth substance loss (n = 46) analyses were measured and compared using a 3D surface texture analyser and scanning electron microscope (SEM) respectively, at baseline and following scaling. Part 2 Pain Perception: a clinical study, which was a split mouth study design including 30 participants with gingivitis and/or mild chronic periodontitis; treated with supra-gingival scaling from teeth #13 to #23. Subjects were randomised to group A or group B. Group A was treated first with PS scaler tips, whereas group B was treated first with conventional scaler tips. Pain perception was recorded using the visual analogue scale (VAS).
RESULTS: In vitro study: both scaler tips caused significant reduction in root substance roughness after scaling (p 0.05) was observed. The PS scaler tip caused statistically significantly less root substance loss (p

BACKGROUND: This study aimed to assess the impact of periodontitis (PD) on the health related quality of life (HRQoL) and oral health related QoL (OHRQoL) of subjects with rheumatoid arthritis (RA) and PD.
METHODS: Subjects from dental and RA clinics were screened. Complete periodontal examinations were performed. Subjects were divided into 4 groups: RA-PD, RA, PD and healthy controls (HC). Questionnaires on characteristics and Malaysian versions of Oral Health Impact Profile (OHIP-14(M)) and Health Assessment Questionnaire (HAQ-DI)) were answered.
RESULTS: A total of 187 subjects were included (29 RA-PD, 58 RA, 43 PD and 57 HC). OHIP-14(M) severity score was highest in the PD group (17.23 ± 10.36) but only significantly higher than the HC group (p
Fulltext Impact of non-surgical periodontal therapy on serum Resistin and periodontal pathogen in periodontitis patients with obesity

Md Tahir K, Ab Malek AH, Vaithilingam RD, Saub R, Safii SH, Rahman MT, et al.

BMC Oral Health, 2020 02 14;20(1):52.
PMID: 32059714 DOI: 10.1186/s12903-020-1039-3

BACKGROUND: Non-surgical periodontal therapy (NSPT) known as gold standard treatment in managing periodontitis. The aim of this study was to investigate the response of NSPT in periodontitis subjects who were obese. Clinical parameters of periodontitis, changes in serum resistin and periodontal pathogens in subgingival plaque were compared before and after NSPT in periodontitis subjects who were obese and with normal weight.
METHODS: A total of 48 periodontitis subjects (obese, n = 18; normal weight, n = 30) were recruited (hereafter will be referred as participants) to participate into a prospective, before and after clinical trial. Obesity status is defined by body mass index (BMI) criteria (obese: ≥30 kg/ m2; normal weight
Modelling the national economic burden of non-surgical periodontal management in specialist clinics in Malaysia using a markov model

Anuwar AHK, Ng CW, Safii SH, Saub R, Ab-Murat N

BMC Oral Health, 2024 Mar 18;24(1):346.
PMID: 38500175 DOI: 10.1186/s12903-024-04094-z

BACKGROUND: Non-surgical periodontal treatment is the mainstay of periodontal treatment. In Malaysia, the prevalence of periodontal disease is substantial among adults with almost half of them having periodontitis. Therefore, we estimated the economic burden of non-surgical periodontal treatment in specialist clinics in Malaysia.
METHODS: Relevant data from multiple data sources which include national oral health and health surveys, national census, extensive systematic literature reviews, as well as discussion with experts, were used to estimate the economic burden of non-surgical periodontal management in specialist clinics in Malaysia in 2020. This estimation was done from the oral healthcare provider's perspective in both public and private sectors using an irreducible Markov model of 3-month cycle length over a time horizon of one year.
RESULTS: In 2020, the national economic burden of non-surgical periodontal treatment during the first year of periodontal management in specialist clinics in Malaysia was MYR 696 million (USD 166 million), ranging from MYR 471 million (USD 112 million) to MYR 922 million (USD 220 million). Of these, a total of MYR 485 million (USD 115 million) and MYR 211 million (USD 50 million) were the direct oral healthcare cost in public and private dental clinics, respectively.
CONCLUSION: The findings of this study demonstrated substantial economic burden of non-surgical periodontal management in specialist clinics in Malaysia. Being a life-long disease, these findings highlight the importance of enforcing primary and secondary preventive measures. On the strength and reliability of this economic evidence, this study provides vital information to inform policy- and decision-making regarding the future direction of managing periodontitis in Malaysia.
