The diagnosis is made by biopsy or puncture of the affected lymph nodes, which must undergo histopathology, serology, or polymerase chain reaction. An 18-year-old woman presented with progressive, painful, right submandibular adenomegaly in the absence of systemic symptoms. She denied the previous contact with cats or any other animals. A computed tomography scan of the cervix showed nodular images corresponding to the affected lymph nodes. The patient underwent a lymph node biopsy, which suggested CSD as the primary diagnosis. The biopsy does not reveal specific diagnoses. B. henselae was confirmed serologically. This case illustrates a typical evolution of CSD in which a patient is affected by subacute lymphadenopathy, but with no epidemiological history. The only certain diagnostic mean was the positive serology of Bartonella. Good general condition, despite pronounced adenomegaly without signs of toxemia, is characteristic of CSD. The lack of more accurate laboratory tests, the difficulty in culturing the pathogen, and the need for histopathology prevent the rapid diagnosis of CSD and contribute to the nonrecognition of this disease. B. henselae testing should be considered when monitoring lymphadenopathy, especially if there is subacute evolution, as in the presented case.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"31 1","pages":"72 - 77"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77091509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no study has been conducted to compare the clinical efficiency between pediatric rotary file systems. Aim: To determine the clinical efficiency (instrumentation time, obturation time, quality of obturation and postoperative pain) of two pediatric rotary file systems following the root canal preparation of primary molars. Materials and Methods: A total of 75 primary molars requiring pulpectomy were selected from children aged 4 to 7 years. These teeth were divided into three groups of 25 teeth each. In the first, second, and third groups, the cleaning and shaping of the root canals were carried out with Pedo-Flex pediatric rotary files (Group PF), Kedo-S pediatric rotary files (Group KS), and, manual nickel-titanium K-files (Group MF), respectively. Obturation was carried out with zinc oxide eugenol cement with an engine-driven Lentulo spiral. The instrumentation and obturation times were recorded. The quality of the root filling was radiographically assessed immediately after obturation. The postoperative pain was evaluated at time intervals of 6, 12, 24, 48, 72 h, and 1 week. Results and Discussion: The instrumentation and obturation times were significantly less with the use of pediatric rotary file systems compared to the manual file system. The quality of obturation was superior in the root canals instrumented with pediatric rotary file systems compared to manual files. There was decreased postoperative pain with the use of pediatric rotary file systems as compared to manual files. In all three groups, postoperative pain decreased over time. The optimally filled root canals showed a significant correlation with the absence of postoperative pain. Conclusions: The use of pediatric rotary file systems for root canal instrumentation of primary molars resulted in the superior quality of obturation in decreased instrumentation and obturating times with the least postoperative pain. The overfilled root canals were not associated with significant postoperative pain.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"21 1","pages":"32 - 40"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85714354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mucormycosis has historically been prevalent in the various parts of world but did not had any diagnostic opportunity before the turn of 20th century. Immunosuppression in any form was always and will forever be the most important ingredients in this disease recipe. Minimally invasive diagnoses with aggressive antimicrobials in addition to the removal of immunosuppression factor are the golden standard of treatment, as oral and maxillofacial surgeons we acknowledge that surgical debridement and various other relatively newer adjunctive therapies have overall reduced the fatal outcomes for such a lethal disease. Aim: This review article focuses on gathering data in relation to immunosuppression due to whatsoever reason and pathogenesis, management, and chance of positive prognosis for patient suffering from mucormycosis . Including surgical and prosthetic options which ascertain descent quality of life for the patient. Materials and Methods: Existing data compilation including the latest research and co-relation of various types of immunosuppression as a nidus for mucormycosis, including the role of novel covid-19 from all relevant electronic databases. Results: Definite co-relation has been stablished for diabetes melitus and covid-19 and speculative co-relation for various types of malignancy and various conditions. Discussion: A strong immunity is an antagonist for mucormycosis, and new advances in field of medicine and surgery have changed the grim look of past where this disease had a 50% mortality rate. Conclusion: Existing literature supports immunosuppression in any form as a nidus for mucormycosis, still further, elaborate research and development is required for identifying the particular cocktail for different diseases process.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"22 1","pages":"10 - 16"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86196086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: To determine if there was any negative impact of dental local anesthesia on the vital medical condition of patients who recently received the Covid-19 vaccine. Materials and Methods: Before participating in the study, patients had to read and sign a consent form. The following treatments were performed under local anesthesia: ten definitive restorations; two tooth extractions; two scalings and prophylaxis; three root planning; and one root canal treatment. Lidocaine with epinephrine was used on three patients, lidocaine without epinephrine on one patient, and scandicaine2% (mepivacaine hydrochloride) on 13 patients. A questionnaire containing nine specific questions was developed for this study, beginning with a patient's personal information. In the second group, we asked about the symptoms after getting the covid 19 vaccine, and in the third group, we asked about the symptoms after dental work. Results and Discussion: With the limitation of this study, it was evident that there was no correlation between vaccination against Covid-19 and local anesthesia in dental treatment with healthy patients. As the Local anesthetics produce anesthesia by inhibiting nerve ending excitation or by blocking the conduction of peripheral nerves. And COVID-19 vaccine works on the body's immune system. Statistical significance was established at P ≤ 0.05.

The disease is characterized by multiple basal cell carcinomas of the skin, multiple keratocystic odontogenic tumors, rib anomalies, and palmar and plantar pits. This article reviews a 3-year follow-up case that we have reported in the Dental University Hospital OMFS clinic at King Saud University, Riyadh, Saudi Arabia. The patient was a 13-year-old female that has been diagnosed with Gorlin–Goltz syndrome in 2018. She had multiple radiolucent lesions, two mandibular OKC, and maxillary dentigerous cyst. The extensive left OKC was treated with marsupialization followed by enucleation. Optimal results with low recurrence rate have been shown after using the marsupialization followed by enucleation and curettage, which agree with the present case results. Unfortunately, there is no gold standard or concrete recommendations that emphasize particular treatment modality. Nevertheless, this approach is considered effective and less invasive in treating OKCs, reducing the lesion size by drainage and decompression up to 47% of the initial size, allowing the preservation of critical anatomical structures. Furthermore, marsupialization prior to enucleation is an appropriate approach in young patients because it is the least treatment modality that interferes with the developmental process of jaws.","PeriodicalId":32335,"journal":{"name":"Saudi Journal of Oral Sciences","volume":"22 1","pages":"189 - 193"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81501156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Healing complications have been reported to be influenced by patients' knowledge and compliance with postoperative instructions. Aim : The goal of the study was to define the influence of the way postoperative instructions delivering method on reducing morbidity and problems experienced after simple tooth extraction. Materials and Methods: A single-blind randomized clinical trial was designed at clinics of Oral Maxillofacial Surgery, Taibah University. Patients were distributed to two classes on a random basis. The first group was provided only with verbal instructions (VI) after dental extraction. The second group was given written and verbal (CVWI) instructions. Postoperative pain, swelling, sleep impairment, oral functions, and general activity were reported using an assessment tool for oral health life quality (OHQ). Results and Discussion: The mean OHQ scores were 14.28 ± 6.36 for VI and 13.46 ± 5.78 for CVWI, which did not indicate a statistical difference (P = 0.50).

Hence, the aim of this study was to assess whether or not associations exist between different types of malocclusions and morphological modifications of the mandibular condyle. Materials and Methods: A systematic literature search was conducted on the Medline database via PubMed interface and supplemented by a manual search via Google Scholar to identify more articles reporting the subject of the review. A combination of controlled vocabulary was used in the search strategy and the final update was stopped on January 2021. The risk of bias was assessed based on the Newcastle–Ottawa Scale. Results and Discussion: Considering the preestablished inclusion and exclusion criteria, 20 articles were retained with 2607 human subjects (967 males/1299 females and 341 not specified, age: 4–60 years). Eighty percent of the selected articles reported associations between malocclusion and morphological changes of the condylar head. Sagittal plane malocclusions produce more changes to the temporomandibular joint components (head of condyle and joint space) (71.93%), while vertical malocclusions lead to the most severe manifestations. Conclusions: Cone-beam computed tomography is the most useful tool for the assessment of osseous morphology of mandibular head condyles and detection of cortical erosion (21.7%).
