A Scientometric Study of Saudi PubMed-Indexed Endodontic Research.

Scientometric studies play a crucial role in quantitatively assessing the impact and quantity of scholarly articles, providing a basis for policy-making and informed decision-making processes. Given the ongoing transformation within the Saudi scientific community across various domains, it is essential to establish a baseline for high-quality endodontic research. A comprehensive search in the PubMed database, using the keywords ["Saudi" OR "Saudi Arabia"] within the time frame of 2014 to 2021. The screening process involved evaluating the title and abstract of each article, with only those classified as endodontic articles included for analysis in this study. The analysis included factors such as the type of paper, the authors, the citations, and the year of publication. Featuring one or more authors affiliated with a Saudi dental institution, 70 papers were specifically categorized as endodontic papers. The most prevalent type of paper was case reports, accounting for 27 articles (28%), followed by literature reviews with 13 articles (18%). The number of authors ranged from one to ten, with a general trend of increasing publication rates over the years. In terms of citations, only four papers received more than 20 citations, while the majority of papers garnered between one and ten citations. Most articles in the field of endodontics exhibited low-level evidence. Therefore, it is recommended that the quality of research output and evidence be enhanced.

Association of Fordyce Granules with Skin Types - A Cross-Sectional Study.

Background: Fordyce granules, sometimes referred to as Fordyce dots, are aberrant sebaceous glands that present as diminutive, non-painful, elevated lesions exhibiting a yellowish or whitish hue, measuring 1 to 3 mm in diameter, and manifesting inside the oral cavity. Likewise, these particles may also be seen in the vaginal region and inside the oral cavity. Aim: The primary objective of the current study is to evaluate the potential association between Fordyce granules and the skin type of individuals who seek dental care at the Dental Clinics of Qassim University. Materials and Methods: The current cross-sectional research was undertaken at the Dental Clinics of Qassim University, with a sample of 87 patients diagnosed with Fordyce's granules. The research consisted of a heterogeneous sample of participants, including individuals of all genders, ranging in age from 18 to 85 years. The study included a comprehensive evaluation of several anatomical regions to identify the existence of Fordyce's granules. This examination was conducted by a single examiner who had undergone calibration. Additionally, the participants' skin types were established using the Baumann Skin Typing System questionnaire. The data that was gathered was afterward analyzed utilizing statistical methods via the use of SPSS software. A pre-set significance level was established at P < 0.05. Results: The distribution of skin types among the study participants with Fordyce's granules were found to be oily skin (51.3%), dry skin (47.9%), sensitive skin (49.3%), and resistant skin (56.3%). The results of the research showed that there was no statistically significant correlation between the two variables, i.e. skin type and the presence of Fordyce's granules. This conclusion is supported by the increased P values of 0.941 for those with oily skin and 0.785 for individuals with dry skin. Conclusion: No relation between skin type and Fordyce's granules in the current study.

Knowledge and Awareness of Detecting Oral Premalignant Lesions among Dental Students, Interns, and Practitioners in Saudi Arabia.

Oral malignant lesions are the most common malignancy of which majority are diagnosed in advanced stages in Saudi Arabia. Patients with oral malignant lesion are first seen by general dental practitioners and dental students. Multiple surveys have been conducted and published to assess the students, interns, and dentists' awareness and attitude toward oral premalignant lesions worldwide. However, little is known about this issue in Saudi Arabia. We aimed to assess knowledge and awareness of detecting oral premalignant lesions among dental students, dental interns, and practitioners in Saudi Arabia. A cross-sectional questionnaire-based survey was conducted and electronically distributed. The questionnaire comprised of three sections including demographic variables, knowledge of risk factors of oral malignancy, and six clinical case scenarios. Descriptive statistics were used, and the results were reported using cross-tabulation and the Chi-square test. A 300 participants answered to the questionnaire, and 83% of respondents strongly agreed that smoking is a risk factor for oral malignancy. However, there was some uncertainty in responses for some more specific oral-related factors, such as a sharp-edged tooth and irritation from dental restoration. Furthermore, the knowledge and awareness of detecting frankly benign and frankly malignant lesions such as fibroma and squamous cell carcinoma are higher comparing to potentially malignant lesion, i.e. lichen planus. Knowledge and awareness of detecting oral premalignant lesions vary based on malignancy factors and by participants academic level. Fibroma and SCC are detected easily among all participants. However, lichen planus was the hardest to diagnose among oral lesions.

Retrospective CBCT analysis of maxillary sinus pathology prevalence in the Saudi Arabian population.

Introduction: Maxillary sinus pathology, particularly its association with odontogenic infections, is a significant concern in dentistry. This retrospective study explored the prevalence of maxillary sinus pathologies and their association with odontogenic infections in Saudi Arabia. Methods: This retrospective study included 411 patients aged 20-80 years. Cone-beam computed tomography was performed to identify the presence, location, and characteristics of odontogenic infections and maxillary sinus pathologies. Patients' age and sex were also recorded. Results: Sinusitis was prevalent in 50.6 % of the cases, with no significant sex or age differences in the pathology distribution. A notable association was found between odontogenic and sinus pathologies, particularly on the left side. Conclusion: A significant prevalence of sinus pathologies, particularly sinusitis, was observed, with an association between odontogenic and sinus pathologies, notably on the left side. While acknowledging the limitations of the study, these findings underscore the need for integrated dental and sinus health assessments.

A Comparative Study of the Assessment of the Accuracy of Willems' and Demirjian's Methods in Dental Age Estimation of the Saudi Arabian Population.

BACKGROUND: The notion that "age is just a number" is sometimes expressed colloquially; however, within the domains of medicine and dentistry, age is not only a numerical value. Rather, it has significant importance in several facets of diagnosis and treatment planning. Demonstrating one's identity is necessary not only in the aftermath of natural calamities or mishaps but also in the context of forensic examination of living persons. Age assessment is a very important tool in forensic odontology and plays a vital role in various fields, including medico-legal matters. The primary focus of the current investigation is to assess the precision and correctness of the data and reliability of Demirjian's method (DM) and Willems' method (WM) for age estimation (AE) among the population of Saudi Arabia. METHODOLOGY: This research was conducted on 300 children from Saudi Arabia, aged seven to 13 years, including both males and females. The assessment of orthopantomography images involved the utilization of both Demirjian's and Willems' methodologies for ascertaining dental age. This determined dental age was then meticulously juxtaposed with the chronological age (CA) of every participant. The data collected underwent a comprehensive statistical analysis, which encompassed the application of the paired t-test. RESULTS: By using both methodologies, it was discovered that the estimated age (EA) exhibited higher values in both men and females compared to the CA. Both Willems' and Demirjian's approaches yielded significantly different results in terms of statistical significance (p = 0.000 and p = 0.000, respectively), as shown by the comparison. CONCLUSION: When comparing Willems' technique to Demirjian's method, it was found that the population under research showed somewhat greater accuracy levels for AE. However, it is important to note that the disparity between these two approaches was relatively small. Consequently, it is imperative to emphasize the necessity for additional research involving a larger sample size to establish the validation of a more region-specific AE method tailored specifically for the Saudi Arabian population.

Ancient Schwannoma: Case Report of an Unusual Entity in an Unusual Oral Location.

BACKGROUND Schwannoma is an uncommon benign tumor that develops from Schwann cells in the peripheral nervous system; 25-50% of such tumors occur in the head and neck. A rare variety of schwannoma, known as an ancient schwannoma, exhibits calcification, cystic degeneration, hemorrhage, myxoid stroma, pleomorphism, and nuclear hyperchromatism. Such characteristics may contribute to this tumor being incorrectly diagnosed as malignant. Almost all reported intra-oral ancient schwannomas behave innocuously. CASE REPORT A 20-year-old man presented to the oral surgery clinic with a right facial swelling that began a few months before. CT and MRI were performed and showed a well-defined cystic lesion anterior to the right masseter muscle, located in the subcutaneous area and measuring 28×24×20 mm. No extension to the surrounding tissues nor any other similar lesions were seen. Microscopic examination revealed an encapsulated nodular mass with cystic cavities, hemorrhage, and variably distributed myxoid and hyalinized stroma. The tumor demonstrated 2 distinct cell distributions: hypercellular areas (Antoni A) and myxoid hypocellular areas (Antoni B). Focal areas in high-power magnification showed atypical cells with hyperchromatic and pleomorphic nuclei. The tumor cells showed diffuse positivity for S-100 in IHC. The diagnosis of ancient schwannoma was made. At 1-year follow-up, there was no evidence of nerve injury or recurrence. CONCLUSIONS One more case of oral ancient schwannoma is added to the literature. This is the first reported in Saudi Arabia. It is prudent to be familiar with the degenerative and cytologic alterations of ancient schwannoma, as this may limit the likelihood of misdiagnosis and unnecessary treatment of this benign tumor, with an excellent prognosis.

Angina bullosa hemorrhagica: report of two cases.

Angina bullosa hemorrhagica (ABH) is a rare benign condition that affects the oral and oropharyngeal mucosa. It is characterized by a rapid eruption of one or more red or magenta blood-filled bullae, which typically involves the soft palate. ABH is a self-limiting condition that heals spontaneously usually within 2 weeks without scarring. ABH is not related to any dermatologic, hematologic, systemic disorders, or other known causes. The etiopathogeneses of ABH are unknown, though several theories have been proposed. Trauma has been suggested as a potential cause for the development of ABH in susceptible individuals. Two cases are presented of ABH, and the differential diagnoses of oral vesiculobullous conditions is discussed. Cognizance and identification of this benign condition is important to prevent misdiagnosis and eventual unwarranted treatment.

Carcinosarcoma Arising from Inverted Papilloma in a Patient with History of Radiotherapy for Sinonasal Squamous Cell Carcinoma.

BACKGROUND Carcinosarcoma of the sinonasal tract is an extremely rare malignant neoplasm; it is often designated as carcinoma with spindle cell or sarcomatoid features. We report a case of carcinosarcoma arising in a pre-existing inverted Schneiderian papilloma in the left maxillary antrum and nasal cavity of a 72-year old male patient. CASE REPORT The patient had a significant history of radiotherapy for squamous cell carcinoma in the sinonasal area, 3 decades ago. The patient presented with chief complaints of left nasal blockage, nasal discharge, anosmia, and occasional epistaxis. Computed tomography scan displayed a lobular soft tissue mass resulting in narrowing of the nasopharyngeal airway with massive destruction of palatal tissue. The lesion was resected via endoscopic surgery. Macroscopically, a white fleshy appearance with necrosis was noted in the submitted specimen. Microscopically, the tumor was composed of pleomorphic epithelial and spindle cells with numerous mitoses and remarkable tissue necrosis. Residual inverted papilloma (IP) with high-grade dysplasia, and minimal foci of moderately differentiated squamous cell carcinoma (SCC) component was present at the tumor margin. A distinct zone of transition of SCC to spindle cell carcinoma (SpSCC) was noted and confirmed by focal positivity of p63 in epithelial and sacromatoid components. The pleomorphic sarcomatoid tumor was positive for vimentin with Ki67 highlighting 70% of tumor cells. A final diagnosis of sinonasal spindle cell carcinoma associated with residual inverted papilloma was rendered. CONCLUSIONS Due to the rarity of such cases, the prognosis and response to treatment is unclear. No effective directed treatment has been developed. Unfortunately, the patient refused any further treatment and died of persistent disease. To the best of our knowledge, only one case of sinonasal carcinosarcoma arising from dysplastic inverted papilloma has been reported. The distinct possibility of previous radiotherapy contributing to development of sarcomatoid features in this neoplasm should also be considered.

Demographic, Clinical and Histopathological Features of Oral Neural Neoplasms: A Retrospective Study.

Intraoral neural neoplasms though unusual may be clinically significant. The aim of this study was to categorize and evaluate oral neural tumors in a large oral pathology biopsy service. With IRB approval, a retrospective search of all neural neoplasms of the oral cavity in the archives of the University of Florida Oral Pathology Biopsy Service spanning from 1994 to 2015 was performed. Extraoral cases as well as cases with insufficient patient information were excluded. A total of 340 out of 164,578 submitted specimens in a 22 year period (0.2%) were included with a mean age of 43.3 years (range: 6-89), and 44% male and 56% female. The most commonly affected locations were: tongue (37.5%), palate (22%), lip (19%), and gingiva (14%). The microscopic diagnoses rendered, in descending order of frequency were: neurofibromas (NFs): 123 (36%), granular cell tumor (GCT): 108 (32%), schwannomas: 61 (17%), palisaded encapsulated neuromas: 39 (11%), benign neural lesion not otherwise specified: 8 (2%), and mucosal neuroma c/w multiple endocrine neoplasia type 2B (MEN 2B): 1 (< 0.5%). Six cases of NF reported a history of neurofibromatosis Type 1 (NF 1). Four cases showed multifocal lesions. Immunohistochemical staining was performed on equivocal cases (25% of the lesions) and all were confirmed by their S-100 positivity. Intraoral neural neoplasms, though uncommon should be in the differential diagnosis of oral soft tissue entities and specific consideration to syndromal linkage is paramount as this may impact patient management.

Unusual Papillary Squamous Cell Carcinoma of the Tip of Tongue Presenting in a Patient Status Post Heart Transplant.

Oral papillary squamous cell carcinoma (PSCC) is an unusual variant of squamous cell carcinoma with a better prognosis. The most common location of PSCC in the oral cavity is the gingiva and buccal mucosa, and it is exceedingly rare in the tongue. Herein, we present a case of PSCC in an 85-year-old male with a history of heart transplant and long-term use of immunosuppression medication. A verrucous pedunculated mass measuring 3.5 cm in the greatest dimension was present on the tip of tongue and a partial glossectomy was performed. Histological diagnosis was well differentiated PSCC with focal and minimal stalk invasion. No vascular nor perineural invasion was identified. Based on the current WHO and AJCC oral cancer staging system, the tumor stage was T2N0M0. The tumor cells were focally positive for p16, but in situ hybridization was negative for low-risk HPV (types 6 and 11) and high-risk HPV (types 16, 18, 31, 33 and 51). To the best of our knowledge, this is the first documented case of PSCC present on the tip of tongue in patients with long-term immune suppression. The pathogenesis, stage and prognosis of this entity are discussed. More case studies with long-term follow up are needed to achieve an accurate tumor stage and definite prognosis.
