Objectives: The aim of this study was to assess the perception of dental hygiene students of the transfer of dental hygienists to medical personnel. Methods: A questionnaire-based survey was conducted on 237 dental hygiene students from March 2019 to July 2019. The questionnaire consisted of a standpoint and the expected changes and disadvantages, prohibition causes with the transfer of medical personnel, and items for the promotion of the campaign. Results: Of the 237 participants, 98.3% agreed to the transfer of dental hygienists to medical personnel. The expected changes were ‘improving social status’, ‘license’s scope’, ‘improving pride of the dental hygienist’, and ‘public oral health’, in that order. The expected disadvantages were ‘no disadvantages’, ‘conflict with related occupation’, and ‘increasing duties’. The disability factors were ‘public awareness’, ‘conflict between dental hygienists’, and ‘opposition from related occupations’. In the promotional items of the campaign, ‘dental hygienists’ efforts’ had the highest frequency after ‘no idea’. Conclusions: A unified strategy that could improve public perception without opposition from other related occupational groups is suggested.

Xerostomia is defined as the subjective complaint of dry mouth with or without hyposalivation, which is insufficient salivary secretion from salivary gland. Xerostomia can lead to multiple oral symptoms such as dental caries, halitosis, burning mouth syndrome, and oral candidiasis, which can significantly impact the well-being of patients, especially in geriatric patients who may already have compromised health. Clinical findings of xerostomia include decreased salivary flow and alterations in salivary composition. These changes can lead to various oral health problems such as dental caries, periodontitis, swallowing and speaking difficulties, taste disturbances, halitosis, mucosal diseases, and burning mouth syndrome. Recognizing these clinical manifestations is essential for early diagnosis and appropriate management. Although several reasons and risk factors have been suggested for xerostomia such as aging, chemo-radiation therapy, systemic disease, and Sjögren’s syndrome, the polypharmacy is recently highlighted especially in elderly patients. Understanding the etiology and risk factors associated with xerostomia is crucial for effective management. To manage xerostomia patients, a multidisciplinary guideline should be established beyond dental care. Through this literature review, we summarized consideration for diagnostic, therapeutic, nursing essentials for the clinical guideline. By addressing the underlying causes and implementing appropriate treatment strategies, healthcare professionals can improve the quality of life for individuals suffering from xerostomia.

Objective: To analyze the overall status and trend of surgery patients in department of oral and maxillofacial surgery at the Armed Forces Capital Hospital in 2013-2017. Method: A retrospective study was enrolled the patient who underwent surgery in the operating room at Armed Forces Capital Dental Hospital from January 2013 to December 2017. Based on their medical records, the frequency of surgery, types of anesthesia, hospitalization period, and times related with surgery were analyzed. Results: A total of 616 operations in 614 patients (609 male, 5 female) were included. The frequency types of surgery were surgical extraction, open fracture surgery, benign tumor resection, orthognathic surgery, implant surgery, salivary surgery, closed fracture surgery, and others in order. The anticipated operation time (84.77 minutes) was significantly different from the operation time (66.17 minutes) and available operation time (92.24 minutes). The interval between operation and surgery start times under local anesthesia were longer than under general anesthesia. Conclusion: To improve efficiency of the operating room, it is necessary to develop a policy to reduce the time required excepting the operation time, and to accurately set the estimated time for surgery.

Objective; To analyze the pre-implantation status of patients served for more than 20 years and to provide fundamental data for policy development. Method; A retrospective study was enrolled the patient who passed the implant deliberation at Armed Forces Capital Hospital and assigned by an expert oral and maxillofacial surgeon from November 2018 to Jun 2019. Based on panoramic radiograph, the intraoral status was analyzed by counting the numbers of missing or to be extracted teeth, measuring sone loss score (BLS, 0: not available due to loss of tooth; 1: Bone loss above cemento-enamel junction of adjacent tooth; 2: Bone loss between the furcation and half of root; 3: Bone loss between half of root and apex; 4: Complete bone loss), and calculating severity index (SI, the highest BLS of the patient ranged 0-IV) and disability indices (DI, I: Bilateral function of at last one pair of molars; II: Unilateral loss of function of molars; III: Bilateral loss of function of molars). Krustal-Wallis test was used to the association of numbers of lost teeth and SI based on DI, and the correlation between DI, the numbers of lost teeth, and SI was analyzed using Spearman Correlation coefficient. Results; A total of 240 teeth in 52 patients (average 47.7 years, 4.5 lost teeth per patient) were included. The average of BLS, SI, DI were 3.3, 3.7, and 2.0, respectively. With regard to the level of DI, the average numbers of lost teeth were increased at 2.0 ± 2.0, 2.8 ± 1.6, and 3.7 ± 1.0 according to DI levels, respectively (P<0.001), and SI were also increased at 2.0 ± 2.0, 2.8 ± 1.6, and 3.7 ± 1.0 according to DI levels, respectively (P=0.034). DI were showed strong (0.763) correlation with the numbers of lost teeth (P<0.001) and moderate (0.378) correlation with SI (P=0.006) Conclusion; Dental implant in military hospital can be treated for the duty soldier who have served during more than 20 years. However, the military patients were showed severe bone loss and loss of teeth, and ranked severity and disability indices above moderate. About 60% of the patients delayed implant treatment and suffered at least unilateral loss of function. Therefore, it is necessary to reconsider the target for implants that require 20 years of service yet, and further research should be conducted to determine reasonable targets for implant based on current implant dentistry.

Root coverage achieved with a connective tissue graft overlaid onto allogeneic demineralized dentin matrix incorporated with rhBMP-2

곽한울,엄인웅,구정귀 대한치과의사협회 2023 대한치과의사협회지 Vol.61 No.11

Autogenous demineralized dentin matrix (DDM) has been widely used in implant dentistry and highlighted as a potential carrier of recombinant human bone morphogenetic protein-2 (rhBMP-2). Allogeneic DDM (Allo-DDM) is comparable to autogenous DDM in safety and effectiveness. The various endogenous growth factors in dentin, including BMP, transforming growth factor, fibroblast growth factor, and insulin growth factor suggest that DDM incorporated with rhBMP-2 (DDM/ rhBMP-2) may exert a synergistic effect that promotes soft tissue healing through angiogenic activity, in addition to its osteoinductivity. This case report describes a successful outcome of root coverage where connective tissue graft (CTG) was overlaid onto Allo-DDM incorporated with rhBMP-2 (Allo-DDM/rhBMP-2).

This study reports the unusual complications of 22-year-old male who presented with sudden hearing loss after the right mandibular third molar extraction under local anesthesia with 3.6 ml of 2 % lidocaine. Total 8.75 ㎎ of oral dexamethasone for 1 week immediately after extraction was prescribed in department of oral and maxillofacial surgery but hearing did not improve after 1 week. As referral to otolaryngology, total 600 ㎎ of oral methylon and hyperbaric oxygen therapies were operated for 2 weeks. The hearing of patient was improved at 6 weeks after extraction but tinnitus was persisted even after 12 months. The reason and treatment were discussed with literature review, searching with the keywords [‘hearing loss’ AND (‘dental’ OR ‘tooth extraction’OR‘teeth extraction’)] in PubMed and Google scholar at October 2019. Total five cases were reported after tooth extraction with local anesthesia. The sudden hearing loss could be associated with local anesthesia containing vasoconstrictors. Early steroid (extensive medication and intra-tympanic injection) and hyperbaric oxygen therapies were recommended within 2 weeks. As a proper treatment, hearing could be improved but other additional symptoms, such as tinnitus, dizziness, might be remained.

김상윤(Sang-Yun Kim),김현석(Hyun-Suk Kim),구정귀(Jeong-Kui Ku),김영균(Young-Kyun Kim) 대한치과이식임플란트학회 2018 The Korean Academy of Implant Dentistry Vol.37 No.1

Purpose: To evaluate clinical outcome of implants and sinus bone grafts in maxillary sinusitis patients. Materials and Methods: This study included 29 patients (59 implants) who contracted maxillary sinusitis before or after sinus bone graft or implantation. Treatment cases were categorized into 3 groups according to the time of sinusitis treatment, the bone graft and implantation; Group I (n=18): Maxillary sinusitis treated before bone graft and implantation, Group II (n=22): Maxillary sinusitis treated after bone graft, but before implantation, Group III (n=19): Maxillary sinusitis treated after bone graft and implantation. Among the groups, mean marginal bone loss (MBL), survival rate, sinus membrane perforation at bone graft, relationship with smoke, primary and secondary stabilities of implant were evaluated. Results: During an average observation period of 70.58 months, Group II showed significantly more MBL than Group I and III (P<.05). The implant survival rates of Group I (94.44±0.24%) and Group III (89.47±0.32%) were significantly higher than that of Group II (63.16±0.50%) (P<.001). Group II showed dominant frequency in maxillary sinus membrane perforation at bone graft surgery. Group II also showed significantly lower primary stability (P<.001), but no statistical difference in secondary stability when compared with the other groups. More smokers were in Group III (P<.001), but no relations with MBL, survival rate and primary/secondary stabilities were found. Conclusions: MBL and frequency of sinus membrane perforation were highest in the Group II, and its survival rate was significantly lower than the other groups. Early diagnosis and treatment of maxillary sinusitis before or after the graft and implantation showed better clinical outcome of dental implants.
