Objectives: To assess pattern of toothpaste usage among young children under 6 years old.
Materials and methods: This was a cross-sectional descriptive study carried out at the Faculty of Dentistry, Universiti Kebangsaan Malaysia. Parents of children below 6 years old were involved. 200 questionnaires were distributed and 136 (68%) were returned for analysis. The questionnaire covered the following parameters: type, frequency, and quantity of toothpaste usage among children, level of parental knowledge of fluoride concentration in toothpaste and selection criteria of suitable toothpaste for their children.
Results: Majority of the respondents (83.1%) said they used children’s toothpaste to brush their child’s teeth and 62.5 % of them knew that the toothpaste used had fluoride in it. Slightly more than half of the respondents (53.7%) said they started brushing their child’s teeth one year after eruption of the first tooth. Almost an equal proportion of the respondents reported using toothpaste twice daily (50.7%) and only 44.1% of them supervised their children’s brushing. Respondents generally used more than a pea-sized toothpaste quantity (53.6%). Taste, fluoride concentration and brand of the toothpaste appeared to be the main criteria that influenced the selection of the toothpaste (55.9%). Income and educational levels of the respondents did not influence the type of toothpaste used.
Conclusion: These findings indicated that although parents were brushing their childrens’ teeth with children toothpaste, they were still unaware of the proper usage and importance of fluoridated toothpaste.
Full mouth rehabilitation of the severely collapsed dentition is one of the most challenging procedures in restorative dentistry. The treatment aims are not only to restore function with sustainable restorations and to provide patients with an aesthetic smile, but also to conserve the remaining dentition and maintain the health of supporting structures. This case report describes the complete oral rehabilitation of a patient with severely broken down dentition and loss of posterior support. Loss of posterior support will not only result in breakdown of remaining dentition in the anterior region due to occlusal overload, it also adds years to the patient’s appearance. A complete treatment plan was outlined involving multidisciplinary team treatment included sessions of oral hygiene instructions and re-assessments, a diagnostic stage with provisional overlay denture at an increased occlusal vertical dimension (OVD), endodontic treatment and retreatment, crown lengthening as well as implant surgery. Final restoration involved both fixed and removable prostheses. Maintenance review was carried out periodically after completion of treatment for two years and good outcome was observed.
The primary obligation and ultimate responsibility of a dental surgeon is not only to restore aesthetic and function, but also to relieve pain which originates from dental pathology or surgical procedures performed. Post operative dental pain is mainly of inflammatory origin. Common traditional oral analgesics, namely salicylates, paracetamol and non-steroidal anti-inflammatory drugs have been the drugs of choice, but are increasingly being superseded by newer designer analgesics, the cyclooxygenase-2 (COX-2) inhibitors. This article reviews the advantages and disadvantages of prescribing common traditional oral analgesics as well as exploring the potential use of COX-2 inhibitors as an alternative to these analgesics for the control of post operative pain in dentistry.
A review of incident oral and maxillofacial biopsies in Kelantan from January 1994 to December 1998 was carried out to evaluate the scope of pathological lesions managed by the two main oral and maxillofacial units in this state. A total of 357 biopsy reports from incident cases of pathological lesions were reviewed. The biopsies were mainly from intra-oral sites (n=326, 91.3%). Females had more frequent oro-facial lesions compared with males (male:female ratio is 0.8:1). The Bumiputera ethnic group had the most number of biopsies (n=321; 90%). The three most commonly observed histopathological groups were the connective tissue hyperplasia (n=90; 25.2%), epithelial dysplasia and neoplasia (n=68; 19%) and salivary gland cysts/mucocele (n=56; 15.7%). The top five most frequent diagnoses were mucocele (n=56; 15.7%), squamous cell carcinoma (n=45; 12.6%), epulides (n=31; 8.7%), pyogenic granuloma (n=25; 7.0%) and fibroepithelial polyp (n=19; 5.3%). Oro-facial malignancies made up almost one-fifth of all diagnoses and squamous cell carcinoma was the most common sub-type. Lymphomas in the oro-facial region (n=8; 11.4%) were more common than basal cell carcinoma (n=7; 10%) and salivary gland malignancies (n=6; 8.5%). Epithelial jaw cysts consisted of 8.7% (n=31) of all diagnoses, where inflammatory types were more common than the developmental types. Odontogenic tumours consisted of 5.6% (n=20) of all diagnoses and ameloblastoma was the predominant type.
The tooth provides a non-shedding surface ideal for microbial and plaque accumulation. Despite being exposed to regular environmental perturbations, the microbial composition and proportions in the plaque often remains in homeostasis and is relatively stable over time. Supragingival plaque sampled from various sites on the tooth surface was pooled and conventionally analyzed for its microbial constituent. Classification of microbial isolates was made based on the characteristics exhibited by the growth colonies, Gram-stained cells, as well as biochemical reactions using the API Identification System kit. Observation was also made of the colony forming units on both non-selective and selective agar culture plates. A variety of bacteria, both of the facultative and anaerobic types, were isolated from the supragingival plaque of the Malaysian population. Among those found to predominate the supragingival plaque include the Gram positive and Gram negative cocci and rods from the genera Streptococcus, Staphylococcus, Actinomyces, Fusobacterium, Corynebacterium, Clostridium, Bacteroides, Veilonella and Lactobacillus. In addition, yeast within the genus Candida was also isolated from the plaque samples.
Tissue regeneration is a rapidly growing field providing a beacon of hope in the field of restorative and endodontics. Root canal treatment involves the removal of pulp tissue and replacement by an inorganic materials where as regenerative endodontics deals with replacement with healthy pulp to revitalize the teeth .Research in the field of tissue engineering and material science have lead to significant progress but still is plague with lots of drawbacks and failures, hence it is still not being adapted as routine clinical procedures .The purpose of this article is to review the advances made in regenerative endodontics and the future scopes.
Adenoid cystic carcinoma (ACC) is a rare malignant tumor that arises within secretary glands, most commonly the major and minor salivary glands. It has a tendency for a prolonged clinical course, perineural invasion, with local recurrences and distant metastases. The three recognized histopathologic pattern of ACC are cribriform, tubular, and solid with the cribriform being most common. Standard treatment for salivary gland ACC is surgery and postoperative radiotherapy. We report a case of ACC of palate in a 30-year-old female and review the literature.
This study was conducted on Royal Malaysian Navy submariners who were having training in France. It was designed to compare the oral health experiences and practices while under water and on land. Methods Eightysix Royal Malaysian Navy (RMN) submariners, who had undergone at least one cycle (288 hours) of under water training, were selected to participate in a self-administered questionnaire survey. Results Seven percent of the respondents reported oro-facial pain and discomfort; 9.3% reported bleeding gums and 12.8% experienced halitosis while under water. Of those experience oral problems, 82% reported disruption of their daily activities while under water. The study showed that 82.5% of them brush their teeth at least twice a day and 94.2% rinse after meals when there were under water. Meanwhile studies on land showed that 90.7% of them brush their teeth at least twice a day and 96.5% rinse after meals. Flossing was not practiced by most of the respondents. Conclusion It is concluded that brushing and rinsing are practiced regularly by submariners regardless whether they are on land or under water but flossing is not a common practice both on land and under water. Dental emergencies, such as toothache, TMJ pain and discomfort do occur during submarine operations and disrupt their daily activities. This might poses a threat to submarine operations.
Deviations from normal occlusion are known as malocclusion. Orthodontics treatment usually is the choice of management of irregularities and abnormalities of their relation to the surrounding structures i.e malocclusions. Patient or parent commonly seeks orthodontic treatment for aesthetic reasons rather than functional problems such as temporomandibular joint dysfunction. With greater demand for orthodontic treatment due to greater awareness of the people towards dental health, good orthodontic treatment outcome would be expected. Good orthodontic treatment outcome usually related to good clinical management of the patients. (Copied from article).
The assessment of pulp vitality is a crucial diagnostic procedure in the practice of endodontics. Dentists should establish their treatment decisions based on good sound information and in the best interests of the patients. Therefore, a definite diagnosis must be established with comprehensive investigation and records before any treatment is carried out1. Since the dental pulp is enclosed in an opaque tooth, the assessment of tooth vitality is undertaken indirectly by: looking for clinical or radiological evidence of pulp necrosis or apical periodontitis; investigating nerve conduction; or examining the blood flow.

Introduction: Nowadays, there is a worldwide trend for universities to utilize the benefits of e-learning as a mechanism to facilitate improvements in teaching and learning. Purpose: The aim of this study is to evaluate the effectiveness of using e-learning in the teaching of fixed prosthodontic course i.e. FPeL.
Materials and Methods: This was a retrospective analysis of questionnaire data, collected from fourth and fifth year dental undergraduates at the Faculty of Dentistry, National University of Malaysia (Universiti Kebangsaan Malaysia, UKM). For fixed prosthodontics (FP), all students had received a series of traditional classroom lectures, seminars, video demonstration, preclinical and Fixed Prosthodontics e-Learning or FPeL in semester 1 and 2 during their 4th year. The questionnaire of 4 sections was administered after the students completed fixed prosthodontics course.
Results: Questionnaires were returned by 136 students (80.9% response rate). Unfortunately, the response rate dropped 12.4% when only 115 students accessed and used the FPeL (68.5%). Majority of FPeL users felt PFeL was beneficial to their learning in the fixed prosthodontic course. PFeL users recommended printable version with detailed explanations, illustrated with more photos and with addition of references.
Conclusions: PFeL assisted users in the learning process of fixed prosthodontics.
Objectives: The objectives of the study were to assess: i) the staining susceptibility of composite resins, ii) the ability of whitening toothpastes in removing stains from composite resins.
Materials and Methods: Thirty specimens from each composite resins: Filtek Z350 (3M ESPE), Filtek Z250 (3M ESPE) and Beautifil (Shofu Inc.) were fabricated. After polishing, specimens were immersed in coffee for 3 days. Specimens were then brushed twice a day for 2 weeks using Colgate Total (Colgate-Palmolive, control group), Colgate Advanced Whitening (Colgate- Palmolive, test group) and Darlie All Shiny White (Hawley & Hazel Chemical Co., test group). Colour changes (?E*) were measured using Spectrophotometer at baseline, after coffee immersion and after brushing. Results were statistically analyzed using one way ANOVA and Tukey’s test.
Results: There was significant difference in terms of colour changes for Filtek Z350, Filtek Z250 and Beautifil after coffee immersion (P0.05).
Conclusions: Filtek Z350 was able to resist staining by coffee better than Filtek Z250 and Beautifil. The whitening toothpastes did not offer added advantage in terms of ability to remove stains compared to ordinary toothpaste.
The aim of the present study was to assess the current approaches and philosophies pertaining to direct restorations, bleaching and root canal treatment amongst general dental practitioners (GDPs) in the Klang Valley, Malaysia. A questionnaire, together with a stamped addressed envelope and an explanatory letter, was sent to 200 GDPs in the Klang Valley in April-July 2005. The GDPs were selected at random. A total of 153 (76.5%) of the GDPs responded to the survey. 46.4% of the respondents stated that the use of amalgam was decreasing whereas 79.7% stated an increase in the use of composite resins. Clinical indication (85.6%) and patients’ demand for aesthetics (73.9%) appeared to be the main factors influencing the choice of restorative materials. Fractured restorations was the main reason for the replacement of amalgam restorations (77.1%) whilst secondary caries was the main reason for the replacement of composite resin restorations (73.9%). Almost two thirds of the GDPs surveyed provided chair side bleaching while 75.8% of the GDPs would supervise home bleaching. Sodium hypochlorite was the most common endodontic irrigant used amongst the GDPs surveyed and cold lateral compaction was the most commonly used obturation technique.
Objectives: To evaluate the marginal microleakage of Class II cavities restored with various types of composite resins.
Materials and Methods: Standard Class II slot cavities were prepared at the proximal surfaces of 40 intact premolars which were divided into 4 groups. Four types of composite resins (Esthet-X-Denstply, USA, FiltekTMZ350- 3M ESPE, USA, Beautifil- Shofu, Japan and Solare P-GC, Japan) were used to restore the slot cavities. All the specimens were thermocycled and immersed in 0.5% basic fuschin dye for 24 hours. The specimens were then sectioned in mesio-distal direction. The marginal microleakage at the occlusal and cervical margin was scored using the ISO microleakage scoring system. Data was entered using SPSS Version 12.0 and analyzed using STATA software programme.
Results and discussion: All composite resins exhibited worse microleakage at the cervical margin compared to occlusal margin. Esthet-X showed significantly better microleakage score at the occlusal margin compared to Beautifil and Solare P. FiltekTMZ350 and Beautifil showed mainly microleakage into enamel only at the occlusal margin. Solare P demostrated better resistance against microleakage at the cervical margin compared to other composite resin tested. Esthet-X, Filtek Z350 and Beautiful is not significantly different from each other in terms of microleakage at the cervical margin.
Conclusion: This study showed that none of the materials used in this study is able to eliminate microleakage. Composite resin restorations exhibited worse micorleakage at cervical margin in comparison to occlusal margin.
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.
Gingival overgrowth is a well-recognized unwanted effect associated with three major drugs / drug groups - phenytoin, cyclosporine and the calcium channel blockers. Cyclosporine is the first-choice immunosuppressant for preventing allograft rejection in patients who have received organ or bone marrow transplants. This report aims to highlight a case in which the patient on cyclosporine therapy had also contracted Hepatitis C virus infection.
Compliance to delivery of orthodontic appliances within specified times and factors which influenced compliance by dental technicians in Selangor was evaluated. This is a prospective 8-month study of 18 trainee/ trained technicians from 4 main government dental laboratories in Kajang, Klang, Tanjong Karang and Shah Alam. Delivery times specified by orthodontists were 1 day for plastic retainer, 3 days acrylic retainer, 5 days active plates (URA), 10 days functional appliances (FA), 10 days transpalatal arch (TPA) and 10 days for quadhelix. Punctual delivery was recorded as ‘compliant’. Compliance was compared between appliances, clinics, technicians, orthodontists and seniority of technicians. The sample comprised appliances from 365 patients; 38 (10.4%) Tanjong.Karang, 114 (31.2%) Kajang, 191 (52.3%) Klang and 22 (6.0%) Shah Alam. The majority of appliances were retainers (66.3%), followed by URA (13.4%), functionals (9.3%), TPA (9.0%) and quadhelix (1.9%). Mean compliance for all appliances in Selangor was 55%. Plastic retainers had highest compliance (77.8%), followed by acrylic retainers (59.9%), quadhelix (57.1%), FA (47.1%), TPA (45.5%) and URA (24.5%). Senior technicians (>3 years in service) were more compliant than juniors (
Platelet Rich Fibrin (PRF) is a natural autologous fibrin matrix and is an effective biomaterial product. The application of PRF in oral surgery is not limited to tissue regeneration, but it has been utilized in several minor and major oral surgical procedures. Numerous studies have proven that either alone or in combination with bone graft, PRF acts as bone and soft tissue regeneration and it is able to stimulate physiological wound healing. This case report will introduce the utilization of PRF combined with autogenous bone graft in restoring four walls dental socket defect due to post-surgical extraction complication and plan for implant placement in the future. It acts in the form of a resorbable membrane and stem cell connector to the bone. After 3 months post-surgery review, there was no signs of infection or tissue rejection and the harvested bone was still viable. The PRF is comparable to commercially available membrane in the market, where clinical results can be predicted and possibility of reduction in post-surgical complications is achieved. This is due to 1) its compatibility with bone graft materials notably autogenous type, 2) induced neovascularisation and 3) reduction in inflammatory reaction. Our team is confident that the result of PRF at the edentulous region for rehabilitation purposes is beneficial and cost-effective to our patients.
Delayed eruption of permanent upper incisors is a cause for concern to patients. It causes aesthetic, function and speech problems. This case report describes a technique of managing impacted dilacerated maxillary central incisors using removable appliances over one and a half year. It is a simple, operator- friendly and economical treatment option with favorable result.
The prevalence of periodontal abscesses in emergency dental clinics was found to be between 8%-14%. The purpose of this study was to study the clinical features of periodontal abscesses seen in a specialist periodontal unit. There were 14 patients with equal distribution of gender. The mean age was 39.6 years. Twelve upper teeth (86%) were found to be involved as compared to two lower teeth (14%). There were more posterior teeth involved, a total of nine teeth (64%) as compared to five anterior teeth (36%). The mean pocket depth associated with the abscesses was found to be 7.4mm. There were ten buccal sites (71%) as compared to four palatal sites (29%). Average temperature of patients was 36.9° C. Only one patient was found to have cervical lympadenopathy (7%). The teeth involved were found to be mostly mobile with mobility of grade I to III (71%).
