Background: In order to emphasize the importance of clinical dental hygienists-led dental hygiene management processes for those with systemic diseases, we tried to identify systemic diseases affecting dental implants based on clinical data. Methods: In order to identify systemic diseases affecting dental implants, literature review was conducted from March 1 to May 31, 2023, and the search period was for research papers published in domestic and foreign academic journals from January 2000 to December 2020. Domestic databases used for search use RISS, Nuri Media(DBpia), and Korea Academic Information (http://www.papersearch.net ; KISS), while overseas databases searched Pubmed for dental implant failures, implants, systemic diseases, and Dental implant and system disease. Results: The cumulative survival rate of implants averaged 94.3 percent and the failure rate was 5.7 percent. Clinical analysis of systemic diseases related to implants accounted for the highest frequency with 13 (100.0%), followed by 8 (61.5%) studies on high blood pressure and smoking, 7 (53.8%) cardiovascular diseases, and 5 (38.5%). In addition, liver disease, thyroid abnormalities, blood abnormalities, organ transplants and infectious diseases were confirmed. Conclusion: Since unregulated systemic diseases are a risk factor for implant failure, clinical dental hygienists should continue to maintain healthy oral conditions by sharing information with patients during periodic preventive dental hygiene management processes such as dental hygiene assessment.

Cleidocranial dysplasia (CCD), which is accepted as an autosomal disorder, is a generalized disorder of bone with severe dental abnormalities. Among the most characteristic anomalies seen are hypoplasia of clavicles or aplasia of clavicles, permanant non-ossification of cranial sutures & fontanels, delayed eruption of the permanant dentition & the presence of unerupted supernumerary teeth. CCD may first be noted by dentist because of many dental problems, so we should diagnose the disorder earlier & understand the development of dentition in CCD to ensure timely intervention with proper periodic dental X-ray.

During diagnostic process of the orthodontic patients, it is not unusual to find palatally erupted canines. Palatally erupted canines are related with the positional abnormalities rather than the tooth size/arch-length discrepancies. It is very important to conserve the original arch shape during traction of palatally erupted canines to their proper position. On the following case, the patient was diagnosed as malocclusion with palatally erupted canines, and were treated by 0.9mm auxiliary arch wire during traction of ectopic canines for maintenance of the original arch shape.

Autism is a life-long neurodevelopmental disorder characterized by qualitative abnormalities in reciprocal social interactions and patterns of communication. Patients with autism are difficult to manage during dental treatment. Thus they need special consideration like physical restraint, conscious sedation or general anesthesia. A 5-year-old male dental patient with autism was reffered to dental treatment under conscious sedation using intramuscular midazolam that creats anterograde amnesia. Dental procedure using midazolm which cause anterograde amnesia can be effective treatment strategy in autism patient.

Burning Mouth Syndrome (BMS) is defined as a chronic orofacial pain syndrome, without evidence of mucosal lesions and other clinical signs of disease or laboratory abnormalities. Patients with BMS complain of burning pain in the mouth, xerostomia and taste disturbances. It is more common among women and the median age of occurrence is about 60 years. BMS may be primary or secondary to other diseases. The mainstay in the treatment of BMS includes antidepressants, benzodiazepines, and anticonvulsants. A few cases of BMS caused due to medication have been reported. The causative drugs include angiotensin-converting enzyme inhibitors, anticoagulants, antipsychotics, antiretrovirals, and benzodiazepines. This is a case report of a patient on antidepressants who developed symptoms of BMS thereby causing a dilemma in management.

McCune-Albright syndrome (MAS) is a disease with clinical features such as fibrous dysplasia in which normal bone tissue is replaced with abnormal fibrous tissue, abnormalities in the endocrine system, and cafe-au-lait spots on the skin. Although MAS patients are generally known to have reduced bone healing ability, postoperative healing after invasive surgical extraction is still not clearly known due to its relatively rare occurrence. In this report, a 25-year-old female patient, who had been diagnosed with MAS and had a history of abnormal bone healing after fractures of her extremities, underwent surgical extraction of the mandibular third molar with surrounding bone removal. Postoperatively, the patient showed favorable soft tissue and bone healing at the surgical site without abnormal findings such as newly developed fibro-osseous lesions, postoperative infection, or osteomyelitis.

Vestibular schwannoma, also known as acoustic neuroma, is a rare benign brainstem tumor surrounding the vestibular division of the 8th cranial nerve. The presenting symptoms are hearing loss, tinnitus, and dizziness. Unabated growth can compress 5th (trigeminal nerve) and 7th (facial nerve) cranial nerve, which can cause nerve dysfunction such as orofacial pain, sensory abnormalities, or trigeminal neuralgia. We report a 51-year-old woman who presented with orofacial dysesthesia on her left side of the face with abnormal findings on 5th cranial nerve and 8th (vestibulocochlear nerve) cranial nerve examination. Brain magnetic resonance imaging scan revealed cerebellopontine angle tumor. She was referred to a neurosurgeon and diagnosed with vestibular schwannoma.

Background: The cancer progression of oral leukoplakia is an important watchpoint in the follow-up observation of the patients. However, potential malignancies of oral leukoplakia cannot be estimated by histopathologic assessment alone. We evaluated genetic abnormalities at the level of copy number variation (CNV) to investigate the risk for developing cancer in oral leukoplakias. Materials and Methods: The current study used 27 oral leukoplakias with histological evidence of dysplasia. The first group (progressing dysplasia) consisted of 7 oral lesions from patients with later progression to cancer at the same site. The other group (non-progressing dysplasia) consisted of 20 lesions from patients with no occurrence of oral cancer and longitudinal follow up (>7 years). We extracted DNA from Formalin-Fixed Paraffin-Embedded (FFPE) samples and examined chromosomal loci and frequencies of CNVs using Taqman copy number assays. Results: CNV frequently occurred at 3p, 9p, and 13q loci in progressing dysplasia. Our results also indicate that CNV at multiple loci-in contrast to single locus occurrences-is characteristic of progressing dysplasia. Conclusions: This study suggests that genetic abnormalities of the true precancer demonstrate the progression risk which cannot be delineated by current histopathologic diagnosis.

Objectives: As medical history before surgery is often based on patient reporting, there is the possibility that patients intentionally hide underlying diseases or that dentists cannot recognize abnormal health states. Therefore, more professional and reliable treatment processes are needed under the Korean dental specialist system. The purpose of this study was to elucidate the necessity of a preoperative blood testing routine prior to office-based surgery under local anesthesia. Patients and Methods: Preoperative blood lab data for 5,022 patients from January 2018 to December 2019 were assembled. Study participants were those who underwent extraction or implant surgery under local anesthesia at Seoul National University Dental Hospital. Preoperative blood tests included complete blood count (CBC), blood chemistry, serum electrolyte, serology, and blood coagulation data. Values outside of the normal range were considered an "abnormality," and the percentage of abnormalities among the total number of patients was calculated. Patients were divided into two groups based on the presence of underlying disease. The rates of abnormalities in the blood tests were compared between groups. Chi-square tests were performed to compare data from the two groups, and P<0.05 was considered statistically significant. Results: The percentages of males and females in the study were 48.0% and 52.0%, respectively. Of all patients, 17.0% (Group B) reported known systemic disease, while 83.0% (Group A) reported no specific medical history. There were significant differences between Groups A and B in CBC, coagulation panel, electrolytes, and chemistry panel (P<0.05). In Group A, the results of blood tests that required a change in procedure were identified even though the proportion was very small. Conclusion: Preoperative blood tests for office-based surgery can detect underlying medical conditions that are difficult to identify from patient history alone and can prevent unexpected sequelae. In addition, such tests can result in a more professional treatment process and build patient confidence in the dentist.
