We initiated to prepare the basic data that could help us to understand the characteristics of patients with physiological halitosis symptoms in Korea and aid in establishing the diagnosis and the prevention protocol for these symptoms. We collected questionnaire and dietary analysis results from the data of 246 adult patients diagnosed with physiological halitosis symptoms, collected the data from the patients’ salivary measurements and the analysis data of patients’ tongue and throat management status. Using the SPSS (IBM SPSS™, Ver. 22.0) program, we performed a frequency analysis, calculating the correlation coefficient Phi with an independence test. The mean age and one standard deviation of patients with physiological halitosis was 41.85±11.63 years. The proportion of women, the proportion of patients who replaced breakfast with fast food or skipped breakfast, with beverage drinking habits such as coffee, tea, or carbonated drink, with irregular or insufficient consumption of water, who recognized their own oral malodor, suffering anxiety or stress over oral malodor, with an introverted personality, with insufficient unstimulated salivation volume, with incorrect tongue management, and with postnasal drip or posterior tongue coating were all statistically analyzed to be significantly high (p < 0.05). As a result of the correlation analysis, the Phi values of the five pairs of the bivariate variables were from 0.203 to 0.394 (p < 0.05). We could suggest the 10 potential common risk factors related to physiological halitosis symptom, and the five pairs of variables with Phi values could be judged to have a moderate correlation.
Various risk factors should be thoroughly evaluated for successful sinus floor augmentation and implant placement. Among them, mucous retention cyst could be commonly found on radiographic evaluation. The aim of this study was to demonstrate sinus floor augmentation using lateral approach and implant placement on maxillary sinus in the presence of mucous retention cyst. Two cases which require sinus floor augmentation and implant placement on maxillary posterior edentulous area were involved in this report. Well-defined radiopaque mucous retention cysts without specific sign and symptom were observed in radiographic evaluation. In one case, sinus floor augmentation was performed simultaneously with implant placement, and seromucous fluid within mucous retention cyst was aspirated with syringe needle during the surgery. In the other case, sinus floor augmentation and implant placement were conducted in two-stage approach, and aspiration was also performed in mucous retention cyst to extract fluid during the sinus floor augmentation. Prosthesis was successfully installed on implants, and no clinical complications were observed on periodic check-up. It could be concluded that sinus floor augmentation and implant placement on maxillary sinus with mucous retention cyst could be successfully performed.
Dentin hypersensitivity is sharp pain arising from exposed dentin in response to stimuli. Over the recent de cades, the number of patients complaining of discomfort caused by dentin hypersensitivity has increased. The aim of this study was to find out the accurate diagnosis and treatment method of dentin hypersensitivity from an expert’s point of view. In a clinical situation, an accurate diagnosis must precede the treatment. For an accurate diagnosis, it is important to objectify and reproduce symptoms during clinical examination after a detailed his tory taking. Treatment of dentin hypersensitivity is often more important as long-term intervention than a one-time treat ment. The invasive and irreversible treatment should be considered as the last resort after attempting sufficient conservative methods. Many types of desensitizers are currently on the market to relieve dentin hypersensitiv ity. Representative methods include nerve desensitization and occlusion of dentinal tubules to reduce movement of the dentinal fluid to relieve pain. However, existing desensitizers have various limitations, and several at tempts are such as bioceramic, nanoparticle, and protein have been made to overcome the limitations. Treatment based on accurate diagnosis and correct understanding of dentin hypersensitivity can reduce the pain and increase the quality of life of many patients.
Dentin hypersensitivity (DH) is one of the most frequently happened chronic discomforts and a challenging condition to manage in dental practice. It presents as a short sharp pain that arises from the exposed dentin in re sponse to thermal, tactile, osmotic, chemical, or evaporative stimuli. This condition impacts oral health-related quality of life, producing significant impairment on patients’ daily life such as speaking, eating, drinking, and toothbrushing. The prevalence of DH varies 4~57 %. The prevalence of DH has been reported higher incidence ranging from 60 to 98% in patients with periodontitis. Generally, it appears that the incidence of DH in most populations ranges from 10~30 %. Although there are a large number of techniques and therapeutic alternatives available in the literature to relieve DH, generally speaking, professionals are confused about the etiology and diagnosis of DH, resulting in the lack of confidence to approach this pathological process effectively. Under standing the DH's mechanism, management strategy, and the choice of materials influence the effectiveness and durability of the treatment of the DH. In this article, the various considerations in the management of DH will be reviewed
One of the major causes of postoperative hypersensitivity following direct composite resin restoration is mi croleakage. Adequate adhesive technique, incremental filling, lining of elastic material, and regulation of light curing speed would be helpful for reducing microleakage via polymerization shrinkage. In proximal box res toration, pre-wedging, sectional matrix system, and proper resin applicator are recommended to form adequate proximal contact and contour.
