MATERIALS AND METHODS: A PubMed, Medline, EMBASE and Google search was undertaken of all controlled clinical trials on the effects of corticosteroids on pain, swelling and trismus after lower third molar surgery. The review was limited to studies published over the last 10 years (2006-2015).
RESULTS: Of the 46 initially retrieved articles, 34 were finally included. Eleven studies compared the effect of 2 similar (but different dose) or different group of corticosteroids. Thirty-one studies reported the effects of corticosteroids on all sequale, 2 reported the outcome on swelling and trismus and another 1 on swelling and pain only. In 16 of the studies, corticosteroid use resulted in significant reductions in pain after third molar removal. Twenty-two out of 29 studies reported reduced swelling against negative control while 18 out of 25 studies reported improved mouth opening. Fourteen studies reported the benefit of corticosteroids on all 3 sequelae, with 71.4% resulted from the use of methylprednisolone.
CONCLUSION: Although there are some conflicting effects, the results of this analysis shows in general the benefits derived from short-term use of corticosteroids in relation to pain, swelling and trismus following third molar surgical extraction, with no side effects observed.
FUNDING: This work was supported by the University of Malaya's High Impact Research grant UM.C/625/1/HIR/MOHE/05.
PATIENTS AND METHODS: This prospective, randomized, double-blind study included 65 patients who required surgical removal of impacted mandibular third molars with Class II or position B impaction (Pell and Gregory classification). Patients were randomly assigned to 1 of 3 groups: dexamethasone, methylprednisolone, or placebo (control). Surgery was performed with patients under local anesthesia. Baseline measurements were obtained preoperatively, and subsequent assessments were made on postoperative day 1, 2, 5, and 7 to measure postoperative facial swelling by use of 2 linear measurements: interincisal mouth opening width and visual analog scale score for pain. The amount of analgesics consumed was recorded. Wound healing also was assessed on postoperative day 7. Descriptive and multivariate statistics were computed, and significance was set at P
MATERIALS AND METHODS: Using CBCT imaging data, 204 mandibular first molars and 201 mandibular second molars were assessed for the interradicular and alveolar bone dimensions, tooth sizes and proximity to vital structures. The cross-sectional mandibular shape and root configuration of these molars were determined.
RESULTS: Distances to the inferior alveolar canal (IAC) from the root apices of the first molar were significantly greater than the second molar. Up to 14.5% of second molars had less than 10mm of vertical bone height between the IAC and furcation bone crest. Interradicular bone width of <3mm was found in 57% of second molars. All first molars in this study had two to three roots while 16% of second molars presented with a single root. The prevalent mandible shape at the first and second molars was the parallel and undercut ridges, respectively.
CONCLUSIONS: The mandibular second molars from samples of a Southeast Asian population presented with greater anatomical difficulties for immediate implant placement which include absent or inadequate interradicular bone thickness, higher incidence of unfavorable mandible shape and increased proximity to vital structures.
OBJECTIVE: The aim of the study was to summarize findings from the available literature to provide up-to-date information on sclerosing odontogenic carcinoma and to analyse clinical, radiological, and histopathological features to obtain information for and against as an odontogenic malignancy.
METHODS: We conducted a comprehensive review of literature by searching Pubmed, EBSCO and Web of Science databases, according to PRISMA guidelines. All the cases reported as sclerosing odontogenic carcinoma in English were included. Data retrieved from the articles were gender, age, clinical features, site, relevant medical history, radiographical findings, histopathological findings, immunohistochemical findings, treatments provided and prognosis.
RESULTS: Mean age at diagnosis of sclerosing odontogenic carcinoma was 54.4 years with a very slight female predilection. Sclerosing odontogenic carcinoma was commonly reported in the mandible as an expansile swelling which can be asymptomatic or associated with pain or paraesthesia. They appeared radiolucent with cortical resorption in radiograph evaluation. Histologically, sclerosing odontogenic carcinoma was composed of epithelioid cells in dense, fibrous, or sclerotic stroma with equivocal perineural invasion. Mild cellular atypia and inconspicuous mitotic activity were observed. There is no specific immunohistochemical marker for sclerosing odontogenic carcinoma. AE1/AE3, CK 5/6, CK 14, CK19, p63 and E-cadherin were the widely expressed markers for sclerosing odontogenic carcinoma. Surgical resection was the main treatment provided with no recurrence in most cases. No cases of metastasis were reported.
CONCLUSION: From the literature available, sclerosing odontogenic carcinoma is justifiable as a malignant tumor with no or unknown metastatic potential which can be adequately treated with surgical resection. However, there is insufficient evidence for histological grading or degree of malignancy of this tumor.
METHODS: The specific PIO questions were as follows: Population: Patients with periapical periodontitis either before or after non-surgical endodontic therapy.
INTERVENTION: IR performed with retrograde preparation and retrograde filling.
OUTCOMES: the healing, treatment complications, and the factors influencing these outcomes after IR. Electronic and hand searches were performed in the Web of Science, PubMed, CINAHL, and Cochrane Library databases. Two authors independently screened the titles and abstracts for eligibility. The risk of bias was performed using the NIH Quality Assessment Tool, and each study was rated as "Good", "Fair" or "Poor". The analyses were performed on the treatment outcome (healing and complications), and the factors influencing the outcome of the procedure.
RESULTS: Fourteen articles were included in the qualitative and quantitative syntheses. One was a prospective cohort study, and the other 13 were retrospective cohort studies. Overall, the evidence of this review was of poor-to-fair quality. The pooled healing rate was 80.2%, and there was a 21.7% of complication rate. Longer follow-up period, the presence of perio-endo disease, the use of non-bioceramic material as retrograde filling, longer extraoral time, and maxillary molar were found to be associated with lower healing rates. However, the differences between the subgroups were not statistically significant.
CONCLUSIONS: The present review showed IR yielded a good overall healing rate with a low complication rate. Taking the quality of evidence into account, more high-quality studies are required to evaluate the validity of the factors that may influence the treatment outcome of IR.
OBJECTIVE: The aim of this study was to determine the positioning and roles of ICT in community pharmacies in the state of Selangor, Malaysia.
METHODS: A cross-sectional study was conducted from November 2018 to January 2019 across 9 different subdistricts in the state of Selangor, including Subang Jaya, Cheras, Puchong, Port Klang, Kota Kemuning, Selayang, Chow Kit, Ampang, and Seri Kembangan. A total of 90 community pharmacists were approached from the 9 subdistricts and invited to participate in the study.
RESULTS: Of the 90 community pharmacies approached, 60 agreed to participate in the study, representing a response rate of 67%. The majority (36/60, 60%) of the respondents were women, and more than half (32/60, 53%) of the community pharmacies were run by young adults (ie, 30 years old and younger). More than three-quarters of the community pharmacies (46/60, 77%) used electronic health records. Half of the community pharmacies used online social media platforms for advertising and promoting their pharmacies. The vast majority of the community pharmacies (55/60, 92%) were using modern electronic payment systems, and some were also using other new electronic payment methods. Moreover, most of the community pharmacies (41/60, 68%) were using software and programs for accounting and logistics purposes. In addition, 47/60 (78%) of the community pharmacies used a barcode reading system for medicines/health products, and 16/60 (27%) of the pharmacies had online stores, and consumers could buy medicines and health products from these pharmacies via their online portal. In addition, 20/60 (33%) of the community pharmacies used at least one of the common online business platforms available in Southeast Asia to sell products/medicines. The telephone was the most commonly used means of communication with patients, although some pharmacies also used email, WhatsApp, SMS text messaging, and other communication platforms.
CONCLUSIONS: This study showed that the majority of community pharmacies in Selangor, Malaysia are using ICT for different purposes. However, there is still limited use of mobile apps to provide health services. Overall, community pharmacies have been adopting ICT apps for pharmacy services but the rate of adoption is relatively slower than that in other sectors of Malaysia.
METHODS: We surveyed four countries to determine the public's understanding of keloids. A quantitative, subjective and cross-sectional street survey was designed using the knowledge, attitudes and practice model principles. The target populations were cities in Ghana, Australia, Canada and England. Surveyors used a hybrid stratified/convenience sampling method. Primary outcomes were prevalence, exposure to keloids as an entity and overall keloid knowledge score compared across demographic groups. Study data have been made fully available for reproducibility and education (https://doi.org/10.17605/OSF.IO/3KZ5E).
RESULTS: There were 402 respondents, with a median age of 32 (interquartile range 25-45.25) years, of which 193 were females. The survey was carried out between June 2015 and October 2017. The prevalence of self-identified keloids was 11% in Ghana, 6% in Australia, 2% in Canada and 7% in England. Prevalence, exposure and knowledge were higher in the Ghanaian population.
CONCLUSIONS: There was association between knowledge, prevalence and the exposure to keloids as an entity. Findings may suggest targeting public health campaigns towards populations where knowledge is lowest, and exposure to and prevalence of keloids are the highest.
MATERIALS AND METHODS: This is a 20-year retrospective study aimed to investigate the prevalence, demographic characteristics, clinical presentations, and the association of oral candidiasis with clinical parameters in oral candidiasis cases reported in the Faculty of Dentistry, Universiti Malaya from 1999 until 2019. A total of 12,964 histopathological records from the Oral Pathology Diagnostic and Research Laboratory (OPDRL) between 1999 to 2019 were retrieved. Oral candidiasis cases were selected according to the inclusion and exclusion criteria. Information of interest was obtained and analysed.
RESULTS: From the total records retrieved, 378 oral candidiasis cases were recorded and 82.8% were diagnosed from smear test. This study showed that oral candidiasis was predominantly reported in female (64.2%) and Indian population (64.2%). The peak incidence was in the sixth decades of life (27.0%). The most commonly affected site was tongue and coated tongue was the most common clinical presentation. More than 50% of the cases had comorbidity and 10.6% were associated with dentures. Ethnicity and site of occurrence were significantly associated (p<0.05) with oral candidiasis.
CONCLUSION: This is the first large-scale study of oral candidiasis cases in Malaysia. The findings of this study are useful for clinical assessment of patients suspected of oral candidiasis.
