An in vitro antimicrobial comparison of miswak extract with commercially available non-alcohol mouthrinses.

The aim of this study was to assess the antimicrobial activity of eight commercially available mouthrinses and 50% miswak extract against seven microorganisms. Corsodyl, Alprox, Oral-B advantage, Florosept, Sensodyne, Aquafresh Mint, Betadine and Emoform mouthrinses were used while 50% aqueous extract of miswak (Salvadora persica) was used against Streptococcus faecalis, Streptococcus pyogenis, Streptococcus mutans, Candida albicans, Staphylococcus aureus and Staphylococcus epidermidis. The ditch plate method was used to test the antimicrobial activity. Inhibition zones of microorganisms around ditches were measured in millimetres. Range, mean and standard deviations were used for comparison of antimicrobial activity. Mouthrinses containing chlorhexidine was with maximum antibacterial activity, while cetylpyridinium chloride mouthrinses were with moderate and miswak extract was with low antibacterial activity. Further research is needed for the substantivity of these mouthrinses and further in vivo/in vitro studies are needed using Biofilm model to substantiate present findings. Dental professionals must exercise caution and provide guidance in assisting their patients in making informed choices regarding their use of mouthrinses for clinical efficacy.

Education level, oral hygiene and smoking habits of an elderly Saudi population in Riyadh.

The aim of this study was to assess the education level, oral hygiene and smoking habits of an elderly population in Riyadh City, Saudi Arabia. The study was conducted at various locations including King Saud University, College of Dentistry Hospital, Riyadh Medical Complex, Military Hospital, vegetable markets and elderly house holds. A convenient sample of two hundred and fourteen subjects, age ranged 50-89 years male and female, were interviewed for education level, oral hygiene and smoking habits. The results showed that twenty-five percent of the sample was illiterate while almost 23 percent were with University Education. Only 46 percent were toothbrush user and 44 percent miswak user. Almost 25 percent were smoker. It is concluded that oral hygiene practices were common and cigarette smoking was not very prevalent. Further studies are needed to look into the other areas of oral health related with elderly population in Saudi Arabia.

Oral hygiene, dietary pattern and smoking habits of Bedouin (nomadic Arabs) population in Saudi Arabia.

The estimated population of the Bedouins are up to two million in the Kingdom of Saudi Arabia, but relatively little information is available about them. The aim of the study was to assess the oral hygiene dietary pattern and smoking habits of Saudi Bedouins population around Medina, Qaseen and Khamis Moshayte areas. Five hundred and twenty five Bedouins (296 male, 229 female) with the age range 2-90 years were interviewed and examined clinically over a period of four months (July to October 1998). It was found that 25% of the subjects were miswak users, 30% used miswak and tooth brush, while 26% never cleaned their teeth. Almost 50% of the subjects were regular in their oral hygiene habits. Seventy percent were rice eaters while meat and dates were second and third preference. Tea was the most common drink with 2-3 teaspoons of sugar per cup. Only ten percent were cigarette smokers and less than 5% used shisha (traditional smoking pipe). It is concluded from the study that within the surveyed Bedouin population one fourth of them never cleaned their teeth while almost the same number used miswak (Chewing stick) to clean their teeth. Rice was the most common food item, while tea with refined sugar was the most common drink. Only 15% were smoker. Further research is needed with a larger and a more representative sample of Bedouins from the Kingdom of Saudi Arabia.

Smoking behaviour and knowledge in high school students in Riyadh and Belfast.

UNLABELLED: Smoking is one of the risk factor associated with onset, severity and progression of periodontal disease. AIM: The aim of the study was to examine the smoking behaviour and dental health knowledge of high school students in Riyadh and Belfast. MATERIALS AND METHODS: Eight schools from Riyadh and 6 from Belfast were randomly selected by cluster distribution sampling method. Two hundred and ninety students from Riyadh and 144 from Belfast were included giving an overall response rate of 85%. The age range was between 16-17 years. A questionnaire was used to assess demography, smoking habits, dental health knowledge and oral hygiene practices. RESULTS: The results showed that 18% of students were smokers; 24% in Belfast and 15% in Riyadh (x2 (1) = 4.29: P = 0.04). 24% of students in Belfast and 56% in Riyadh smoked at least 1 cigarette per day. 61% of students had bleeding gums although 85% stated that they brushed their teeth at least daily. Bleeding on brushing was common with 53% of Belfast students compared with 65% from Riyadh. Students in Belfast (2.51 +/- 1.15) had significantly higher mean scores for their knowledge about gum health compared with Riyadh students (2.21 +/- 1.44) (t = 2.29: P = 0.02). There was no differences in knowledge about oral health and smoking between the students. However, non-smokers from Belfast and Riyadh (3.32 +/- 1.60) had greater knowledge about oral health and smoking than those who smoked (2.81 +/- 1.45) (t = 2.73: P = 0.007). There was no difference in knowledge about gum health between smokers and non-smokers. CONCLUSIONS/RECOMMENDATIONS: Smoking is more prevalent in Belfast but more cigarettes are smoked in Riyadh. As non-smokers had greater knowledge of the ill-effects of smoking upon their oral health, there is a need to develop location specific interventions to control smoking habits in late adolescence.

The relationship between periodontal disease and blood glucose level among type II diabetic patients.

The aim of this study was to determine the relationship between periodontal disease and the blood glucose level among type II non-insulin dependent diabetic mellitus (NIDDM) subjects. Forty subjects, 20 in each group, of healthy and diabetic subjects, ages ranged 20-70 years, were examined at King Saud University, College of Dentistry. Clinical examination included frequency of oral hygiene practices, periodontal status by using the Community Periodontal Index of Treatment Needs (CPITN), fasting blood glucose level (FBGL), and random blood glucose level (RBGL). Unstandardized orthopantomograms (OPGs) were taken for radiographic findings. The number of missing teeth (tooth loss) was assessed from the radiographs. The results showed that periodontal disease severity was high among diabetic subjects. Diabetic subjects brushed less frequently, and they had a higher blood glucose level than healthy subjects. The mean CPITN score was compared with mean blood glucose level and the severity of periodontal disease. There was a steady increase in blood glucose level with increase in CPITN scores, i.e., CPITN score 13.5 to 19.12 corresponded with 142 mg/dl and 173.2 mg/dl FBGL, and 184.2 and 199.12 mg/dl RBGL among diabetic subjects. The study indicated that diabetic subjects should improve their oral hygiene practices and control of blood glucose levels should be emphasized. Further studies are needed among diabetics and healthy subjects from the general population with better sampling techniques and a larger sample size.

Back & neck problems among dentists and dental auxiliaries.

In the practice of dentistry, stress, tension, and postural practices can contribute to back and neck problems. Two hundred and four dentists and dental auxiliary (87 males and 117 females) in Riyadh city, Saudi Arabia were surveyed to determine the prevalence of postural problems. The candidates were interviewed and observed during practice. The data obtained showed that 111 (54.4%) of the subjects complained of neck pain and 150 (73.5%) complained of back pain. Only 37% of those complaining of back pain sought medical help. Within the limitations of this study, it might be concluded that neck and back pain among dental personnel are not of a severe nature.

Prevalence of ocular injuries, conjunctivitis and use of eye protection among dental personnel in Riyadh, Saudi Arabia.

AIMS: To find out the prevalence of ocular injury and infection among dental personnel in Riyadh, Saudi Arabia. PARTICIPANTS: Two hundred and four dental personnel. METHOD: A questionnaire completed by researchers and observation during practice. RESULTS: The response rate was 81%. Dentists and dental technicians had a similar prevalence (42.3%) of foreign bodies in their eyes during the period of one month. Almost 50.5% of dentists rarely had foreign bodies in their eyes, while only 22.2% of dental technicians claimed the same. The majority of dental surgery assistants (73.6%) never experienced foreign bodies in their eyes. Only 27.0% of female personnel had foreign bodies in their eyes as compared to 73.0% of male personnel, while only 28.5% of females had conjunctivitis as compared to 71.4% among male personnel. 75% of regular eye protector wearers (EPW) never had foreign bodies while 67.2% EPW never had conjunctivitis. Dental technicians were more prone to ocular injury, 13.8% as compared to 4.4% of dentists. Only 30% of the regular eye protector wearers suffered ocular injury. CONCLUSIONS: Protection of the eyes should be emphasised and practised at undergraduate level. The awareness of eye protection should be highlighted at all clinical and research symposia. Further studies should be conducted to assess the financial implications of ocular injuries and infections in dental institutions and practices. Recommendations are made for universal precautions and the observation of safety at work guidelines by all dental team members.

The antimicrobial effects of seven different types of Asian chewing sticks.

There are various plants, which are used as chewing sticks in different parts of the world. Several studies have been reported on the antimicrobial effects of chewing sticks on oral bacteria. The aim of this study was to compare the antimicrobial effect of aqueous extract of seven different types of chewing sticks found in Pakistan and other Asian countries. The ditch plate method was used to test the antimicrobial activity of seven Asian chewing sticks. It was found that at there was antimicrobial effect on Streptococcus fecalis at 50% concentration of Kikar (Acacia arabica) from Pakistan and Arak (Salvadora persica) from Saudi Arabia. The inhibition zones up to 2 mm were found in those two chewing stick extracts. It is recommended that the chewing sticks will be a great help in developing countries with financial constraints and limited oral health care facilities for their populations.

Hepatitis B awareness and attitudes amongst dental health care workers in Riyadh, Saudi Arabia.

This study was done to investigate the current awareness and uptake of the hepatitis-B vaccination, as well as any changes in patterns over the years. A questionnaire was distributed among all dental staff, including dental specialists, general dentists, hygienists and dental surgery assistants at the dental department of the Military Hospital, Riyadh. Out of 126 DHCW, 112 (88.2%) responded. Ninety-six (85.7%) completed full course of vaccination, 4 (3.6%) did not intend to, be vaccinated and 10 (8.9%) were naturally immune. Of the 96 vaccinate, 42 (43.8%) did not confirm the vaccine efficacy by serological tests. And 54 vaccinate who had post-vaccination serology test, 26 (48.2%) did not check the results of the test. It is concluded from the study that in spite of greater acceptability of the HB vaccine by the DHCW, still a large proportion of them need further advise on the importance of post-vaccination serological tests.

Prevalence and severity of dental fluorosis in Al-Qaseem province--Kingdom of Saudi Arabia.

OBJECTIVE: To assess the oral health status, especially prevalence and severity of dental fluorosis among an urban and rural population of Al-Qaseem province. DESIGN: World Health Organization (WHO) oral health form was used to survey the population. SETTING: Subjects were surveyed from Urban and rural schools, Government and non-governmental organizations, administrative and training institutes of Buraida city and villages of Ain Al-Juwa and Al-Asiah. SUBJECTS: Eight hundred male subjects were surveyed in 12, 15, 35-44 and > 65 years age groups. Four hundred urban and four hundred rural subjects were examined. One hundred in each group. RESULTS: It was found that fluorosis is more prevalent in rural than urban population. 24-67 percent of 12, 15, 34-44 and > 65 years were with dental fluorosis both in urban and rural areas. 12.5 percent of the population examined were with moderate to severe dental fluorosis. Eight percent of the urban and 16.3% of rural population were with moderate to severe dental fluorosis. CONCLUSIONS AND RECOMMENDATIONS: Rural population have more prevalent and severe dental fluorosis as compared to urban population of Al-Qaseem province. There is a need of preventive oral health programs with community education on their diet and water consumption. There is a need to improve water supplies and defluoridation of water sources in affected areas. Multiple sources of fluoride should be analysed and prevented. From treatment need point of view, there is also a need to meet the increased demand of cosmetic restorations for aesthetic units of dentition.

Assessment of periodontal status with CPITN and conventional periodontal indices.

This study compared CPITN with plaque index (PlI), gingival index (GI), papilla bleeding index (PBI), and probeable pocket depth (PPD). 52 patients were examined, mean age 43 years. Partial mouth random recording (2 upper and 1 lower or 1 upper and 2 lower sextants) was made by CPITN of 150 sextants, and at 6 sites around each tooth in each sextant for each index using a pressure-sensitive probe, with Newman tip and Williams markings, and a WHO 621 tip, probing pressure 0.25 N. Ranges of each index were compared with corresponding CPITN data. Most (71%) sextants had CPITN scores of 4, indicating periodontitis. None had CPITN scored 0 or 1. A given CPITN code was found to represent extremes of ranges for all other indices evaluated. There was no relation between CPITN and PlI or GI, nor did CPITN reflect the number of sites affected per sextant, but there was a tendency for CPITN to relate with PBI and PPD. It was concluded that CPITN may be used as a general indicator of bleeding and pocket depth, but not of plaque or gingivitis. Other indices are required to reliably assess chronic inflammatory periodontal disease status in a given mouth.

Effect of X-ray beam vertical angulation on radiographic assessment of alveolar crest level.

Periodontal diseases are diagnosed and monitored by various methods. Probing pocket depth measurements and dental radiographs are two of the most commonly used methods. The aim of this study was to assess the effect of x-ray beam vertical angulation on radiographic assessment of alveolar crest level in five human mandibles. A standardized technique was used to take bitewing radiographs with -10 degrees, 0 degree and +10 degrees angulation of X-Ray beam. The range of the mean differences at individual sites was from 1.84 mm (0.58 +/- SD) to 3.70 mm (1.01 +/- SD). It was found that there was a wide range of over or underestimation of the alveolar crest level due to a change in beam angulation. It was concluded that, to monitor patients with periodontal disease or treatment outcomes, it is important to have reproducible images and bitewing film holders should be used to minimize the X-Ray beam angulation error in general dental practice.

The antimicrobial effects of extracts of Azadirachta indica (Neem) and Salvadora persica (Arak) chewing sticks.

Chewing sticks (Miswak) is most commonly used int he Middle East and Indian Subcontinent Salvadora persica (Arak) and Azadirachta indica (Neem) are commonly used as oral hygiene tools in different parts of the world, Several studies have demonstrated the anti-plaque anticarious and antibacterial effect of these sticks. The aim of this study was to compare the effectiveness of antimicrobial activity of Neem and Arak chewing stick's aqueous extracts at various concentrations. The microbial inhibition was measured using blood agar and ditch plate method up to 48 hous. The pH of Neem extract was 6.1 and of Arak was 4.9 Data suggested that both chewing stick extracts are effective at 50% concentration on strept mutans and Strept faecalis. Arak extract was more effective at lower concentrations for Strept faecalis. The effect may be due to the difference of their chemical composition and variability in their PH. Further research is needed to extrapolate other plants used for oral hygiene. Chewing sticks are recommended as oral hygiene tools for health promotion in developing countries.

The effect of propolis on dentinal hypersensitivity and level of satisfaction among patients from a university hospital Riyadh, Saudi Arabia.

Propolis has been used since ancient times in folk medicine for its beneficial effects. It is a mixture of resin, essential oils and waxes mixed with bee glue; also it contains amino acid, minerals, ethanol, vitamin A, B Complex, E, Pollen and highly active ingredient known as Bioflavenoid (Simon Martin 1991). To date, there have been no studies done on desensitizing effect of Propolis in vivo. So, the aims of this study are to evaluate the effect of Propolis in a clinical trial on subjects with dentinal hypersensitivity, and to assess the level of satisfaction among subjects after they have used the Propolis. Twenty six Saudi female subjects at King Saud University, College of Dentistry, Riyadh, Saudi Arabia, age ranged from 16-40 yr. (mean = 23 yrs.), were included in the study over a period of four weeks. The Cervical Dentinal Sensitivity (C.D.S.) was assessed by two methods: 1--cold air stimuli. 2--Subjective reporting of pain, with a modified questionnaire (Gillam 1997) and a numerical scale 0-10 (Downie et al 1978). The patients were followed up for four weeks after using Propolis, there were two recalls, and the first recall was after one week and the second recall after four weeks of the base line. The results between the base line findings and after four weeks were statistically significant. Eighty five percent of the subjects were found highly satisfied; the Propolis had significant effect on dentinal hypersensitivity during the study period. Further research is needed with double blind clinical trial on a large sample size.

Knowledge of dental health and diseases among dental patients, a multicentre study in Saudi Arabia.

The aim of this study was to assess the knowledge of dental patients about dental health and diseases. A questionnaire was developed with three sets of questions, 1-general knowledge of dental conditions, 2-use of alternate methods in prevention and treatment of dental diseases, 3-awareness about personal oral health. Six hundred questionnaires were distributed in 6 cities from 4 different regions (i.e. Makkah, Riyadh, Tabuk, Gizan). 367 respondents (61% response rate) constituted 233 (63.5%) male and 134 (36.5%) female with the age range 11-70 years (mean 30 +/- 11.9). The data were analyzed by SPSS version 9.0 and results presented in frequency distributions. 99% male and 96% female considered their teeth for chewing food, 97% male and 96% female knew that increased carbohydrate intake and poor oral hygiene are related to tooth decay, 89% male and 96% female used toothbrush and paste to prevent dental diseases and 75% male and 66% female were regular user of miswak (chewing sticks.) 67% male and 59% female visit dentist, only in pain. 46% used miswak after their meals, only 14% of the subjects used miswak on their lingual and palatal surfaces of teeth, while 38% of the subjects used clove as remedy for toothache, 25.6% used saline and 10% used lemon for bleaching their teeth. 15% considered honey important for their good oral health. Regarding personal oral health, 35% had pain in gums, 36.8% were with bad breath, 28% had tooth hypersensitivity, and almost 50% used toothbrush twice daily while 42% had bleeding gums. It is important to note that knowledge and awareness about dental health and disease conditions are better in male subjects, dietary habits and oral hygiene methods need to be addressed in future investigations. There is a need to provide more health education to female subjects to improve their oral health.

A comparative study of propolis and saline application on human dentin. A SEM study.

The purpose of this study was to compare the texture changes of dentinal surfaces after the application of propolis and saline. Twenty-four recently extracted human premolar teeth were obtained from the Division of Oral and Maxillofacial Surgery, King Saud University, College of Dentistry, Riyadh. The teeth were classified as sound, periodontally involved and with recession. Forty-eight, 3 x 3 mm dentin disc specimens were prepared and only 24 specimens were treated with propolis (pH 8.5) and saline (pH 6). They were treated in 4 categories i.e.: (1) no application of any material (control); (2) propolis for 60 seconds; (3) propolis for 120 seconds and (4) saline for 60 seconds. All experimental specimens were burnished with cotton pellet with propolis and saline for the prescribed time. All specimens were prepared for scanning electron microscopy (SEM) with sputter technique, (Blomlof and Lindskog, 1995), and examined in the SEM (Jeol, Japan) operated at 25 KV with a tilt angle between 0-30 degrees. The bar was 10 mm and magnification 2000x. There were dentinal tubules occlusion in all three groups of dentin treated with propolis for 120 seconds. The propolis was better than saline in occluding dentinal tubules. It may be suggested that further research is needed for double blind clinical trials of propolis in patients with dentinal hypersensitivity.
