Planning the Restorative Dental Treatment at the Time of Coronavirus Pandemic: A Two-arm Strategy.

The high risk of infection with coronavirus forced dental practices to decline/limit oral healthcare services to emergency and urgent conditions. Under this policy, the economic burden on dental professionals and their employees was immense. With the prolonged duration of coronavirus health crisis, it was clear that dentists and associated workers and companies cannot bear the cost of longer suspension of regular dental services. At this point, calls have been made for gradual return to regular dental clinical practice. However, dental health professionals around the world realized that oral care services should be tailored to fit the time of COVID-19 pandemic. An important question to be raised here is regarding planning the dental treatment during the time of coronavirus pandemic. Should a dentist plan the dental treatment in a different way to that at a normal time? This paper aims to propose a simple strategy to plan the restorative dental treatment at the time of coronavirus pandemic. The aim of this strategy is to expand the range of oral care services and minimize the risk of infection with this deadly virus. The role of the shortened dental concept and minimum use of aerosol- /droplet-generating procedures have been emphasized. Keywords: Coronavirus, COVID-19, Dental treatment, Pandemic, Shortened dental arch.

Oral Cancer: Awareness and Knowledge Among Dental Patients in Riyadh.

More than 50 % of oral cancer cases are diagnosed at advanced stages. Public knowledge about oral cancer can help in prevention and early detection of the disease. The aim of the present study was to assess the levels of awareness and knowledge about signs and risk factors of oral cancer among dental patients in Saudi Arabia. A self-administered questionnaire was used to collect information from 1410 randomly selected patients attending dental departments within public hospitals in Riyadh, Saudi Arabia. The collected data were analyzed using SPSS software. The significance level was set at P < 0.05. The study revealed that only 62.4 % were aware of oral cancer. Some 68.2 and 56.5 %, respectively, were able to correctly identify tobacco and alcohol as risk factors. More than two thirds of subjects had no knowledge about any signs of oral cancer. Participants with lower than university education were significantly less aware, and had much less knowledge, of the signs and risk factors of oral cancer. The knowledge regarding oral cancer among Saudi dental patients is alarmingly low. Interventions to improve public knowledge about oral cancer and attitudes towards early diagnosis and treatment are urgently indicated.

Efficacy of Subgingivally Delivered Satranidazole in the Treatment of Type 2 Diabetes Subjects with Chronic Periodontitis: A Randomized Controlled Clinical Trial.

BACKGROUND: The present clinical trial was designed to investigate the effectiveness of subgingivally delivered satranidazole (SZ) gel as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis. METHODS: Sixty-four subjects with probing depth (PD) ≥ 5 mm and who were diagnosed with type 2 diabetes were selected. Thirty-two subjects each were randomly assigned to SRP + placebo (Group 1) and SRP + SZ (Group 2). The clinical outcomes evaluated were plaque index (PI), gingival index (GI), clinical attachment level (CAL) and PD at baseline, 1 month, 3-months and 6 months. RESULTS: At 6 months, Group 2 had greater mean reduction (4.73 mm) in PD as compared to Group 1 (2.09 mm; p < 0.05) and also a greater mean CAL gain (3.92 mm versus 1.64 mm; p < 0.05). CONCLUSION: The use of 3% SZ gel, when used as an adjunct to non-surgical periodontal therapy in subjects with periodontitis, achieves significantly better clinical results than initial periodontal treatment alone.

Oral Paleomicrobiology: Study of Ancient Oral Microbiome.

BACKGROUND: Paleomicrobiology is a special branch of micropaleontology concerned with the study of bacterial fossils. We have used the term 'oral paleomicrobiology', as in this review we have focused on the ancient oral microflora. Recently, dental calculus and dental pulp have been identified as rich sources of ancient microbial DNA. Study of this ancient genetic material opens a new door to the ancient world. This review gives an overview of history of ancient DNA research, various techniques of analyzing ancient DNA in dental calculus and dental pulp, and the implications of the oral paleomicrobiology. MATERIALS AND METHODS: A comprehensive literature search was performed in the following databases-pubmed, medline and google scholar for studies published before 10 April, 2015. The following keywords were used- 'ancient DNA', 'ancient oral flora, 'oral paleomicrobiology' and 'oral microbiome', '16S rRNA sequencing'. To obtain additional data, a manual search was performed using the reference lists of selected articles. RESULT: As a result of literature search, 27 articles were found in pubmed, 12 in google scholar and one in medline. Eight more articles were selected from the reference list of selected articles. CONCLUSION: The combination of microbiology and paleontology has brought a revolution in the study of human evolution and microbial communities. The naturally well-preserved samples of microbial DNA from dental pulp and microbial colonies trapped in dental calculus are a potential source of microbial genetic material, which will prove invaluable in resolving mysteries of the past. This may be a beginning of a new era of oral paleomicrobiology, which will contribute in our studies about prevention of disease by establishing symbiosis between human beings and their microbiome.

Malignant transformation of calcifying cystic odontogenic tumour - a review of literature.

Calcifying cystic odontogenic tumour (CCOT) has been classified as an odontogenic tumour. Ghost cell odontogenic carcinoma (GCOC) is the malignant counterpart of CCOT. This paper aims to review the literature regarding malignant transformation of CCOT. A literature search was done via the National Library of Medicine PubMed interface, searching for articles relating to malignant transformation of CCOT. From these articles, references were obtained, and from their references lists, pertinent secondary references were also identified and acquired. After reviewing the literature, we found 26 cases of GCOC which developed from CCOT. Malignant transformation of CCOT was seen more commonly in the maxilla. Histologically, changes such as increased nuclear/cytoplasmic ratio, atypical mitotic figures have been reported after malignant transformation. Immunohistochemical analysis has shown an increased expression of ki-67 and p53 in tumour cells. Malignant transformation of CCOT, although rare, mostly takes place in recurrent and long standing cases.

Antimicrobial effects of citrus sinensis peel extracts against periodontopathic bacteria: an in vitro study.

BACKGROUND: Use of plant extracts and phytochemicals with known antimicrobial properties may have great significance in therapeutic treatments. OBJECTIVE: To assess the in vitro antimicrobial potential and also determine the minimum inhibitory concentration (MIC) of Citrus sinensis peel extracts with a view of searching a novel extract as a remedy for periodontal pathogens. MATERIALS AND METHODS: Aqueous and ethanol (cold and hot) extracts prepared from peel of Citrus sinensis were screened for in vitro antimicrobial activity against Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Prevotella intermedia, using agar well diffusion method. The lowest concentration of every extract considered as the minimal inhibitory concentration (MIC) values were determined for both test organisms. Confidence level and level of significance were set at 95% and 5% respectively. RESULTS: Prevotella intermedia and Porphyromonas gingivalis were resistant to aqueous extracts while Aggregatibacter actinomycetemcomitans was inhibited at very high cncentrations. Hot ethanolic extracts showed significantly higher zone of inhibition than cold ethanolic extract. Minimum inhibitory concentration of hot and cold ethanolic extracts of Citrus sinensis peel ranged between 12-15 mg/ml against all three periodontal pathogens. CONCLUSIONS: Both extracts were found sensitive and contain compounds with therapeutic potential. Nevertheless, clinical trials on the effect of these plants are essential before advocating large-scale therapy.

P27 expression in pleomorphic salivary gland adenoma.

AIM OF THE STUDY: This study aims to characterise alterations in the immunohistochemical expression of p27 in normal tissue of the salivary gland surrounding pleomorphic adenoma and in the tumour cells of pleomorphic adenoma. MATERIAL AND METHODS: A retrospective study of data including 120 cases of pleomorphic adenomas (66 female, 54 male) retrieved from the files of the Oral Pathology Departments of Aleppo University, Syria and Al-Farabi Dental and Nursing College. Immunohistochemical expression against p27 was examined in the selected cases. The percentage of p27-positive nuclei was semi-quantitatively assessed by two independent observers and scores were given. The statistical analysis included the use of descriptive statistics and proportional frequencies. RESULTS: The results showed that P27 nuclear staining with high staining (moderate to strong positive staining in more than 50% of nuclei, depending on the percentage of nuclei for the cells) was noted in tumour duct cells of pleomorphic adenoma in 90 (75%) cases out of 120, while 30 (25%) cases showed low staining (positive staining in less than 5% of nuclei, depending on the percentage of nuclei for the cells). CONCLUSIONS: Our data suggests that p27 might have a minor role in the development of pleomorphic adenoma.

Knowledge and attitudes of Saudi dental undergraduates on oral cancer.

Oral cancer awareness among future dental practitioners may have an impact on the early detection and prevention of oral cancer. A cross-sectional survey was undertaken to assess the current knowledge of future Saudi dentists on oral cancer and their opinions on oral cancer prevention. A pretested questionnaire was sent to 550 undergraduate dental students in the fourth, fifth, and sixth year of the Al-Farabi College for Dentistry and Nursing, Riyadh, Saudi Arabia. Questions relating to knowledge of oral cancer, risk factors, and opinions on oral cancer prevention and practices were posed. Four hundred seventy-nine students returned the questionnaire (87.1 %). Eighty-one percent of respondents correctly answered questions relating to oral cancer awareness. Eighty-seven percent of respondents felt confident in performing a systematic oral examination to detect changes consistent with oral malignancy. Interestingly, 57 % of respondents had seen the use of oral cancer diagnostics aids. Thirty-seven percent of respondents felt inadequately trained to provide tobacco and alcohol cessation advice. There is a need to reinforce the undergraduate dental curriculum with regards to oral cancer education; particularly in its prevention and early detection. Incorporating the use of oral cancer diagnostic aids should be made mandatory.

Diagnosis of oral pigmentations and malignant transformations.

BACKGROUND: Oral pigmentation is a common finding in the mouth. Pigmentation can be either normal or abnormal discoloration of oral mucous membrane. The purpose of this review mainly focuses on the main oral pigmented lesions, in order to help the clinicians establish a better approach towards the patients with pigmented oral lesions and to provide thorough knowledge regarding such lesions for patient reassurance, early definitive diagnosis and prompt treatment. METHODS: Relevant data concerning oral pigmented lesions, clinical features and the possibility of malignant transformation of such lesions were reviewed thoroughly from pubmed literature published in English. Pigmented lesions affecting the skin were not included in our review. RESULTS: Few pigmented lesions have been identified and their tendency to become malignant has been reported in the literature. The oral lesions showing malignant transformation reported were mostly case series. Unfortunately, due to lack of long-term studies, follow ups and randomized controlled studies in this respect it was difficult to draw a statistical analysis. This information is quite crucial for general dental practitioners to improve their understanding regarding oral lesions and to differentiate between normal and diseased conditions, so that they can master the skill of differential diagnosis, definitive diagnosis and prompt treatment. CONCLUSION: Oral pigmentation may present as focal, multifocal or diffused macular or tumefactive lesions. They may greatly vary in color as blue, purple, brown, gray or black depending on the quantity and site of melanin in the tissues [1]. Etiology of pigmentation can be multi factorial. Mostly pigmentation is physiologic but at times it can be a precursor of severe diseases. Lesions may be caused by localized harmless accumulations of melanin, hemosiderin or exogenous metals or they may be a sign of underlying systemic or genetic disease. A few lesions may be associated with life-threatening medical conditions that require immediate intervention. The differential diagnosis for any pigmented lesion is extensive, as it includes examples of endogenous and exogenous pigmentations. Although biopsy is a helpful and necessary aid in the diagnosis of focally pigmented lesions, with diffuse pigmentation lesions require a thorough dental and medical history and laboratory investigations.

Prevalence of wheat allergy in Al-Kharj, Saudi Arabia.

BACKGROUND: Wheat allergy has been suggested to represent an important allergic disease. This study collates clinical and laboratory aspects in patients with wheat allergy in Al-Kharj city, Saudi Arabia. METHODS: Total and specific IgE were measured in 15 suspected cases of wheat allergy. Protein allergenicity was assessed with Western blotting. RESULTS: Significant elevation of total and specific IgE was found in 4 cases. Basophlia was also demonstrated on blood film. Western blotting results showed 2 bands (83 and 40 kDa). CONCLUSION: Wheat allergy must also be considered when planning treatment of asthma and eczema of adult patients.

Animal allergy among husbandry personnel in Riyadh.

BACKGROUND: The importance of specific animal allergy in immunopathology of asthma and atopic diseases remained to be defined. METHODS: We measured total and specific IgE. Western blotting of some allergens was also characterised. RESULT: There was a significant elevation of IgE in 3 persons among 15 samples collected. Western blotting showed common husbandry allergens from 3 sources that have common allergenicity. CONCLUSION: Exposure to animal products exacerbates allergic asthma in adults, suggesting that preventive measures should be taken to reduce their sensitivity.

Estrogen, Progesterone and Androgen Receptor in Primary and Recurrent Pleomorphic Salivary Adenomas.

OBJECTIVE: Our study aimed to characterize alteration in the immunohistochemical expression of estrogen, progesterone and androgen receptor in the tumour cells of primary pleomorphic adenomas and recurrent pleomorphic adenomas. METHODS: A retrospective study of data including 30 cases of primary pleomorphic adenomas (PA) without recurrences and 15 cases of recurrent pleomorphic adenomas were examined (RPA). RPA included 8 males and 7 females. Immunohistochemical expression of estrogen, progesterone and androgen receptor was examined in the selected cases. The percentage of slides was semi-quantitatively assessed by two independent observers and scores were given. The statistical analysis included the use of descriptive statistics and proportional frequencies. RESULTS: AR expression was identified in 12 (40. %) out of 30 cases of (PA) pleomorphic adenomas and 7 of 15 cases recurrent pleomorphic adenomas (RPA) (46 %). The results showed that ER and PR expression were negative in PA and RPA. CONCLUSION: Androgen receptors might have role in pathogenesis of PA and RPA. Estrogen and progesterone receptors have no role in development of recurrent pleomorphic salivary adenoma.

Awareness and practice of dentists in gulf cooperation council countries regarding medication-related osteonecrosis of the jaw - A web-based survey.

Background/purpose: Medication-related osteonecrosis of the jaw (MRONJ) is a serious complication among dental patients undergoing treatment with antiresorptive medications such as bisphosphonate and denosumab. The present survey investigated the awareness and practice of dentists in the Gulf Cooperation Council (GCC) countries regarding MRONJ. Materials and methods: This questionnaire-based study was conducted among dental practitioners in all six GCC countries. A questionnaire was designed and distributed among all potential participants via different social media platforms. SPSS version 22 was used for data analysis, and P-value <0.05 was considered statistically significant. Results: Overall, 1685 dentists from the six GCC countries participated in the present study. The surveyed dentists revealed relatively fair practices and awareness regarding MRONJ and its prevention, with the majority reported asking their patients about history of anti-osteoporotic medications (67.8%), recording name of the medication (73.1%) and duration of treatment (75.5%). However, the majority of the participants were unconfident about the duration of drug holiday prior to dental surgical interventions (70.6%) and the overall good level of knowledge/practice related to MRONJ was just 50.6%. The regression analysis revealed that previous exposure to MRONJ cases and attending a seminar, course, meeting, or conference about osteonecrosis of the jaw were independent predictors for positive awareness/good practice regarding MRONJ (P < 0.05). Conclusion: The results show inadequate awareness and practices of dentists practicing in GCC countries regarding MRONJ, with significant variations among the countries. Therefore, appropriate interventions such as periodic continuous education courses are required to improve dentists' knowledge and practices regarding MRONJ.

Expression of p21 is dependent on or independent of p53 in carcinoma ex pleomorphic adenoma (undifferentiated and adenocarcinoma types).

Our study is aimed to characterize alteration in the immunohistochemical expression of p21 and p53 in normal tissue of the salivary gland surrounding carcinoma arising in pleomorphic adenoma, and the tumor cells of carcinoma arising in pleomorphic adenoma as well as to identify whether the induction of expression p21 is dependent on or independent of p53 in carcinoma arising in pleomorphic adenoma. A selected series of 27 cases of carcinoma ex pleomorphic adenoma (undifferentiated and adenocarcinoma types) was examined. The results showed that p21 and p53 expression was negative in the most components of normal tissue of the salivary gland surrounding carcinoma arising in pleomorphic adenoma. p21 was strongly expressed in carcinoma cells in 9 (33.3%) cases out of 27. p53 was strongly expressed in carcinoma cells in 10 (37%) cases out of 27. Also a co-expression of p21 and p53 showed negative nuclear staining in 9 cases, while 8 cases expressed positive staining. p21 expressed negative nuclear staining in 4 cases but p53 expressed positive staining in the same cases. p21 expressed positive nuclear staining in 6 cases but p53 expressed negative nuclear staining in the same cases. Our data suggest that inactivation of p53 and p21 may play an important role in the evolution of carcinoma ex pleomorphic adenoma. Also p21 behaves as dependent on or independent of p53 in carcinoma arising in pleomorphic adenoma.

Dentists' Perception of Oral Potentially Malignant Disorders.

OBJECTIVES: Dentists play a major role in the diagnosis of oral potentially malignant disorders (OPMDs) that may lead to malignancy. Their knowledge on OPMDs and the risk factors associated with malignant disease needs to be sufficient. The aim of this study was to assess the level of knowledge, attitudes, and awareness of OPMDs amongst general dentists and dental specialists working in Saudi Arabia. MATERIAL AND METHODS: Questionnaires were distributed to dentists working in Saudi Arabia. A total of 303 dentists participated in the study. The questionnaire included 20 questions on knowledge, attitudes, and awareness of OPMDs. RESULTS: The response rate was 55%. There was no significant difference between general dental practitioners and dental specialists regarding leukoplakia, which is the most common OPMD (P > .05) and in identifying tobacco and alcohol as the main risk factors for malignant transformation of OPMDs into cancer (P > .05). However, there was a significant difference (P < .05) between specialists (75.3%) and general practitioners (52.3%) in the diagnosis of OPMDs. There was a significant difference (P < .05) between specialists (63.5%) and general practitioners (28.0%) in recognising the likelihood of malignant transformation of proliferative verrucous leukoplakia. There was a significant difference between specialists (61.2%) and general practitioners (25.2%, P < .05) in recognising the erosive form or atrophic type of oral lichen planus, considering that it is more likely to undergo malignant transformation. CONCLUSIONS: Dental specialists have better knowledge and awareness than general dentists regarding OPMDs. Improved continuous education programmes on the risk factors and diagnosis of OPMDs should be organised to train dentists.

Assessment of Knowledge and Attitude of Dental Students towards HIV and Its Oral Manifestations in Saudi Arabia-A Cross-Sectional Study.

BACKGROUND: It is essential for practicing dentists to have adequate knowledge of HIV/AIDS and its implications in the dental practice. Their attitudes should also be up to the professional expectations. This study aimed to assess knowledge of HIV/AIDS infection and attitudes towards its patients among dental students in Saudi Arabia. METHODS: A questionnaire was prepared and distributed among a sample of dental students in Saudi Arabia. Twenty questions related to knowledge, attitudes, and oral manifestation of HIV were presented. RESULTS: A total of 405 questionnaires were completed (67% response rate). Participants showed low knowledge of safety regarding HIV (39.5%) and 44.2% indicated that they would take an HIV test after needle stick injury. The proportion of correct answers regarding transmission of HIV through saliva, cardiopulmonary resuscitation, and aerosols by hand pieces was 41%, 37.5%, and 26.4%, respectively. Almost 50% of the surveyed dental students expressed unwillingness to treat HIV-positive patients. Poor knowledge was noted regarding oral manifestations of HIV (32.7%). Of the participants, 57.8% indicated that infection control procedures are very important for the treatment of HIV patients and 50.6% believed that a dentist can make a decision to reject the treatment of HIV patients. According to the participating dental students, the three major oral manifestations in HIV patients are hairy leukoplakia (47.4%), oral candidiasis (44.7%), and Kaposi's sarcoma (43.5%). CONCLUSION: Inadequate knowledge and unprofessional attitude towards HIV/AIDS patients were identified among this group of dental students in Saudi Arabia. Dental educators and health care planners in Saudi Arabia should plan to promote the knowledge and attitudes of dental students in Saudi Arabia towards the treatment of HIV patients.

Study of Lateral Wall Thickness of the Maxillary Sinus in Left and Right Sides for Female and Male: A Cross Sectional Retrospective Study Using Cone Beam Computed Tomography.

BACKGROUND: Dental implants are considered the first option to replace missing teeth. Alveolar bone resorption gradually progresses following tooth extraction leading to loss of vertical bone dimension for implant placement. The lateral window approach is the most commonly used procedure to treat vertical bone loss. OBJECTIVE: The aim of the present study is to evaluate the Lateral Wall Thickness (LWT) of the maxillary sinus and determine the influence of gender and side on maxillary LWT. METHODS: This study involved a cross sectional retrospective study. Cone- beam computed tomography data were collected from 99 patients with a total of 198 maxillary sinuses that met the inclusion criteria. The patient age ranged between 18 to 35 years. On the selected sagittal section, the points of measurement are determined by a perpendicular line at 5 mm from the lowest point of the sinus floor. Measurements were taken at four different areas; first premolar (P1), second premolar (P2), first molar (M1), and second molar (M2). Descriptive statistics were used to calculate mean lateral wall thickness for each tooth, and student's t-test was used to test the effect of gender and side on maxillary LWT. RESULTS: The greatest mean LWT was observed around the left first maxillary molar (2.43±0.82), while the lowest mean LWT was observed around the right second maxillary premolar (1.62±0.61). There was no significant difference in the LWT around any tooth (M1 p=0.56, M2 p=0.92, P1 p=0.14, P2 p=0.19). CONCLUSION: There was no significant difference in both males and females of the lateral wall thickness in the left and right side of maxillary sinus.
