Dental anxiety and dental care - a comparison between Albania and Germany.

BACKGROUND: The present study is the first in Albania on dental fear and dental anxiety and also in the field of psychosocial medicine. The purpose of this study was to find out whether there are differences in dental anxiety using the Dental Anxiety Scale, their level of psychological distress using the Brief Symptom Inventory-18 and the evaluation of oral health among Albanian and German patients. METHODS: This study was conducted in the period from December 2019 to July 2020, a sample of N = 263 patients (133 Germans, 130 Albanians) using the Dental Anxiety Scale questionnaires to determine anxiety before dental treatment and the Brief Symptom Inventory-18 to evaluate psychological distress. Moreover, the patients answered questions regarding their oral health and dental care. In Germany, there were four refusals to entrance in the study due to various reasons, in contrast to Albania, where there were no refusals at all For the purposes of this study, data on both populations aged 14 years and older were used. RESULTS: The questionnaires results were calculated for all participants. The current subjective health status of Albanian patients was assessed to be significantly worse than that of German patients (p < 0,000). Germans were more susceptible to signs of Anxiety (p < 0,000), Depression and Somatization and scored higher on the Dental Anxiety Scale and the Global Severity Index (p < 0,000) than Albanian patients. Additionally Albanian patients scored significantly lower on the preventive care index (p < 0,000). Despite an elevated DAS anxiety level, German patients reported going to the dentist more frequently than Albanian patients. CONCLUSION: The results showed that between both populations differences in dental anxiety, psychological distress and oral health exists. Patients from Germany report more psychological distress and described more dental anxiety compared to Albanian patients. Albanian patients reported not utilization on oral health care.The implementation of educational programs and preventive measures, would contribute to raising awareness about the importance of oral health and increased use of dental services.

Legal conflicts in forensic dentistry: practice and methods of resolving them.

OBJECTIVE: Aim: To investigate and analyze legal conflicts in forensic dentistry of Ukraine. PATIENTS AND METHODS: Materials and Methods: A comparative research method for determining the common and distinctive features of the legal regulation of forensic dental expertise as a subcluster in the legislation of Ukraine. The descriptive (monographic) method reveals the problematic aspects of forensic dental examination through the lens of local normative and general normative connotations. The structural-functional research method made it possible to systematize the peculiarities of forensic medical and forensic dental expert activity. CONCLUSION: Conclusions: The analysis of legal conflicts made it possible to come to the following conclusions, that in Ukraine today there is no specific legal act that would regulate the aspects of performing dental activities. Forensic dental examination in Ukraine, in accordance with the legislation, is an examination of the actions and inactions of the dentist. The adoption of normative legal acts in the field of dental activity and forensic dental examination in Ukraine would make it possible to determine the specifics of establishing facts and circumstances that indicate a violation of the patient's rights.

Differences in periodontal parameters between SPT patients who regularly and irregularly visited the dental clinic analyzed at tooth level: a 14-year retrospective cohort study.

The purpose of this study was to evaluate the periodontal status of patients who routinely did SPT, when compared to patients that did not SPT. This retrospective cohort study was conducted at a general dental office from 2001 to 2019. Patients aged 18 to 81 years who visited the dental office over a 10-year period were assigned into two groups: an SPT group, which included patients who continually visited the dental office for SPT one or more times every year, and an irregular group, consisting of patients who did not visit the dental office at least once a year. A total of 7307 teeth (SPT group) and 4659 teeth (irregular group) were evaluated, and the periodontal conditions were compared between the first and latest visits. Multiple regression analysis was used to analyze the results. The mean follow-up time was 13.74 years. The risk factors for improvements in probing pocket depth included age, sex, smoking, diabetes mellitus, molar tooth, and irregular SPT group (p < 0.001), and that for a positive bleeding on probing site was the irregular group (odds ratio 2.94; 95% confidence interval 2.63-3.29). This study showed that lack of routine in attending the SPT program significantly decreased the periodontal parameters, thus highlighting the importance of continuing with the program to maintain the periodontal health.

Scheduling mobile dental clinics: A heuristic approach considering fairness among school districts.

Mobile dental clinics (MDCs) are suitable solutions for servicing people living in rural and urban areas that require dental healthcare. MDCs can provide dental care to the most vulnerable high-school students. However, scheduling MDCs to visit patients is critical to developing efficient dental programs. Here, we study a mobile dental clinic scheduling problem that arises from the real-life logistics management challenge faced by a school-based mobile dental care program in Southern Chile. This problem involves scheduling MDCs to treat high-school students at public schools while considering a fairness constraint among districts. Schools are circumscribed into districts, and by program regulations, at least 50% of the students in each district must receive dental care during the first semester. Fairness prevents some districts from waiting more time to receive dental care than others. We model the problem as a parallel machine scheduling problem with sequence-dependent setup costs and batch due dates and propose a mathematical model and a genetic algorithm-based solution to solve the problem. Our computational results demonstrate the effectiveness of our approaches in obtaining near-optimal solutions. Finally, dental program managers can use the methodologies presented in this work to schedule mobile dental clinics and improve their operations.

"It's a waste of time coming here, better go to private clinics with wider options for treatment": patient's perception on dental services provided in Fiji.

BACKGROUND: Oral health can influence the quality of an individual's life. Patient's perception of the service plays a vital role in understanding the reasons as to why a patient may be satisfied or dissatisfied with the service that they accessed at a dental setting. As no studies have been done in Fiji until now, this study aimed to explore the perceptions of patients on services provided by the largest dental clinic in the Central/Eastern division in Fiji. METHOD: A qualitative study was used to collect data from patients who visited the Colonial War Memorial Hospital (CWMH) dental clinic in Suva Fiji from 5th August to 31st October, 2020. All patients above the age of 18 of both genders and from any ethnicity who visited the CWMH dental clinic during the period of data collection were included the study. A total of 25 participants were interviewed for this study using the in-depth interview method till data saturation occurred. A semi-structured open-ended questionnaire was used to collect data using face-to-face in-depth interviews. The data were transcribed and analyzed using manual thematic analysis process to gather the themes and sub-themes for the results. RESULTS: A total of 25 patients were interviewed, with a majority (n = 14) being men and 15 were of I-Taukei background. Five themes emerging from data analysis include: Waiting time before treatment, Cost of Treatment, Accessibility of services, Privacy and confidentiality and Range of treatment options. The patients had an expectation to get the best treatment but face many hurdles while trying to get the treatment that they expect. The shortfalls on the part of this dental clinic caused an onset of negative perception among its users. CONCLUSION: This study shows an overall dissatisfaction with regards to services delivery among the patients who use the CWMH dental clinic for dental care purposes. The decision makers need to look into the genuine concerns that have been raised by patients in order to create improvements in services delivery and create an array of satisfaction for its patients.

Evaluation of staff satisfaction after the implementation of a daily goals sheet in the routine work of an oral outpatient department and its influence on work efficiency.

BACKGROUND: In March 2021, the supervision group of our hospital inspected the daily work of the outpatient department in the branch and found many problems in the process, such as an excessive number of daily check-up forms, nurses' confusion regarding the daily check-up process, and the omission of daily check-up items. Therefore, focusing on these problem, our hospital established a quality improvement team to conduct a status survey and perform this study. This study evaluated the feasibility, availability and sustainability of using a daily goals sheet in the routine work of a stomatological outpatient department and investigated the satisfaction of the nursing staff with the sheet. METHODS: After determining the theme of this study through the status survey, 60 nurses were randomly selected and divided into an experimental group and a control group by a random grouping method. Then, the study was divided into two stages: Applying the PDCA cycle method and following the MECE (Mad Exclusive, Collectively Exhaustive) principle to design, manufacture and apply the daily goals sheet. After the expert group performed Stage one, an analysis of work efficiency and routine omissions and a staff satisfaction survey were carried out. The results of the groups either using the daily goals sheet (n = 30) or not (n = 30) were analysed and compared. RESULTS: The average work time of the daily goals sheet group was 15.20 ± 1.70 min, and that of the nondaily goals sheet group was 25.30 ± 2.70 min (P < 0.001). The omission rate was 0% in the daily goals sheet group and 16.67% in the nondaily goals sheet group. Staff satisfaction with the use of the daily goals sheet was high. CONCLUSION: The daily goals sheet can make routine work more efficient and convenient in a stomatological outpatient department. It is recommended for use in stomatological outpatient departments or hospitals.

Antibiotic utilization in emergency dental care in Stockholm 2016: a cross sectional study.

OBJECTIVES: To investigate systemic antibiotics utilization in emergency dental care and to determine the most common treatment measures performed during emergency visits in public versus private emergency care in Sweden. MATERIAL AND METHODS: Two questionnaires were answered by dentists at one large public and one large private emergency dental clinic in Stockholm, Sweden. The first questionnaire pertained to the emergency care provided to patients (n = 1023) and the second concerned the dentists' (n = 13) own knowledge and attitudes towards antibiotic treatment and oral infections. The results of the questionnaires were tested using a Chi-square test. RESULTS: Sixteen percent of all patients seeking emergency dental treatment received antibiotics. The most common overall reason for visiting an emergency clinic was pain (52%, n = 519). The most common diagnoses made by the participating dentists in the public clinic were tooth/filling fracture (17%, n = 91) and gingivitis (14%, n = 76), while in the private clinic they were tooth fracture (29%, n = 146) and symptomatic apical periodontitis (15%, n = 72). Although the number of patients with infection was higher in the public care clinic, there was no significant difference in total number of antibiotic prescriptions between the two clinics. The rate of patients receiving antibiotic prescription as sole treatment was 41% (n = 34) in private care and 31% (n = 18) in public care. Thirty-one percent (n = 4) of dentists prescribed antibiotics for patients with diagnoses normally not requiring antibiotics, citing reasons such as time limitation, patient request, patient travel, patient safety, and follow-up not possible. CONCLUSION: Although antibiotic prescription frequency among the Swedish emergency care dentists participating in this study was low, areas for improvement could include providing education to improve dentists' knowledge on both antibiotic prescription in emergency dental care and treatment of acute oral infections.

Cases of dental clinic visits by COVID-19-confirmed patients.

OBJECTIVES: This study aims to review cases of dental visits by patients who had confirmed COVID-19 infection in Seoul and Gyeonggi-do. It analyses the patterns of infection transmission among dental healthcare professionals and dental clinic visitors. METHODS: This study obtained data from reports on disease trends and press releases published by the Korea Centers for Disease Control and Prevention (KCDC) on its COVID-19 website. RESULTS: After examining cases of patients with a confirmed COVID-19 infection, 24 people (10 in Seoul and 14 in Gyeonggi-do) visited the dental office 1-13 days prior to their case confirmation; however, the spread of the virus in the dental office was not confirmed. CONCLUSION: The WHO and KCDC guidelines must be followed to curb transmission of the SARS-CoV-2 virus among dental patients and professionals.

Airborne particles and microorganisms in a dental clinic: Variability of indoor concentrations, impact of dental procedures, and personal exposure during everyday practice.

This study presents for the first time comprehensive measurements of the particle number size distribution (10 nm to 10 µm) together with next-generation sequencing analysis of airborne bacteria inside a dental clinic. A substantial enrichment of the indoor environment with new particles in all size classes was identified by both activities to background and indoor/outdoor (I/O) ratios. Grinding and drilling were the principal dental activities to produce new particles in the air, closely followed by polishing. Illumina MiSeq sequencing of 16S rRNA of bioaerosol collected indoors revealed the presence of 86 bacterial genera, 26 of them previously characterized as potential human pathogens. Bacterial species richness and concentration determined both by qPCR, and culture-dependent analysis were significantly higher in the treatment room. Bacterial load of the treatment room impacted in the nearby waiting room where no dental procedures took place. I/O ratio of bacterial concentration in the treatment room followed the fluctuation of I/O ratio of airborne particles in the biology-relevant size classes of 1-2.5, 2.5-5, and 5-10 µm. Exposure analysis revealed increased inhaled number of particles and microorganisms during dental procedures. These findings provide a detailed insight on airborne particles of both biotic and abiotic origin in a dental clinic.

How the high-volume evacuation alters the flow-field and particle removal characteristics in the mock-up dental clinic.

The exposure risk of droplets and aerosols emitted from the oral cavity to the dental professionals and patients has received more attention especially the ongoing outbreak of COVID-19. The aim of this study is to address the question about how the use of the high-volume evacuation (HVE) alters the risk profiles compared with the situation only personal protective equipment (PPE). The risk profiles of the different situations were analyzed in terms of droplet velocity, flow field characteristics, and particle removal efficiency. The ultrasonic scaling with suction was performed in the mock-up experimental dental clinic, and the instantaneous moment when the HVE acted on the droplets was visualized using a laser light scattering technique. From the results of the velocity profiles, the hypothesis about the moderate effect of the HVE on high-velocity small droplets near the mannequin's mouth had been firstly proven in this study. The suction can be characterized as low-threshold equipment to bring substantial benefits to reduce the area of the contaminated region. Once the cooperation of suction, the pair of vortexes that were in the face shield area of the dental professional would be eliminated, removing the high-level contaminated region near the breathing area of dental professionals. Compared with the low and medium volume evacuation, the particle removal efficiency of the HVE was more stable at 60%. The research will provide references to the HVE recommendation in the dentistry clinical practice guidelines.

[Routine Epidemic Prevention and Control and Treatment Process Reengineering of Outpatient Dental Care].

The coronavirus disease 2019 (COVID-19) pandemic is the most severe global public health emergency in over a hundred years. We have collected and organized prevention and control information from China and other counties and used it as an important reference for designing routine epidemic prevention and control measures and treatment process reengineering of outpatient dental services. Suggestions are made in the following aspects: standard precaution is adopted for all patients based on situational risk assessment conducted by the medical staffs; transmission-based precautions are adopted in addition while caring for patients who are suspected of or have been confirmed of having infectious diseases, in which scenario, standard precautions may not be enough; regarding clinical services, the triage process should be further improved, clinical service delivery areas should be redesigned to maximize safe distances, minimally invasive dentistry procedures should be prioritized for treatment, and postponement of treatment should be recommended appropriately; infection prevention and control guidelines should be regularly updated and relevant trainings provided to the medical staffs accordingly; COVID-19 incidents associated with delivery of dental care should be documented and evaluated; it is also important to communicate with Chinese and international colleagues and stress research and professional training.

[Professional satisfaction of the medical staff of the scientific and practical dental complex].

A survey of dentists and managing clinics-branches of the scientific and practical dental complex showed a high level of professional satisfaction. The main advantages in the activities of rapidly developing network-type dental clinics that actively implement the most advanced, unique technologies and tools have been identified. The main motivational factors that positively affect the result of staff activities, as well as reduce their degree of professional satisfaction, are identified. Moreover, according to the results of respondents' answers, approaches were identified to improve the motivating component in personnel management, as well as to level existing problems within the team. Studying the opinions of medical personnel (doctors and managers) will help the administration to analyze the potential of the personnel potential of clinics and will contribute to the development of plans to improve the organization of staff work and network development.

[The medical social characteristic of patients of private stomatological clinics].

The article deals with results of anonymous questionnaire survey of patient in private dental clinics "LiderDent" (241 respondents of able-bodied age) and "GelioDent" (419 respondents of able-bodied age). The purpose of the study was to investigate peculiarities of medical and social characteristics. The questionnaire included questions concerning social status of respondents, their financial condition, self-assessment of dental health and its maintenance at the proper level for a number of parameters, as well as evaluation of work of private dental organizations. The assessment of dental health of elderly patients established that 58.1% of respondents rated their dental health as good, 27.8% as satisfactory; and 4.1% of respondents estimated their dental health as bad. The analysis included also evaluation of negative health habits of respondents resulting in dental diseases and afflict damage to teeth and oral cavity. It was found that more than half of respondents had higher education. They consider themselves as financially secure, they did not smoke and had good condition of oral cavity. They choose dentists according recommendation of friends and seek dental care only in case of obvious signs of disease. The analysis of possible reasons for seeking dental professional revealed that 75.5% of respondents seek dental care when there are "obvious signs of disease and deterioration of health", 21.2% "when first signs of disease occurred" and 3.3% "only in critical situation". It is concluded that dental professional of private medical centers should be more widely carried out sanitary and educational work with population in order to increase the medical activity of patient, as well as to increase their awareness of ways and means of maintaining the dental health.

Psychological distress and anxiety compared amongst dental patients- results of a cross-sectional study in 1549 adults.

BACKGROUND: This study aimed to identify anxiety in dental patients visiting a dental clinic using the Dental Anxiety Scale, their level of psychological distress using the Brief Symptom Inventory-18 and therefore identifying a correlation between these groups as well as their gender and age. METHODS: An adult sample of N = 1549 patients (865 females, 779 males) was examined over the course of three years using the Brief Symptom Inventory-18 to evaluate psychological distress and the Dental Anxiety Scale to determine anxiety before dental treatment. Evaluations were conducted according to age and gender. RESULTS: There was no correlation between different age groups of the sample the Dental Anxiety Scale. Anxiety, depression and GSI were more frequent in patients below the age of 46 than above. Women were more susceptible to signs of Anxiety and Somatization and scored higher on the Dental Anxiety Scale and the Global Severity Index than male patients. There was a significant positive correlation between scores of the BSI-18 categories: Somatization, Anxiety and Depression and the DAS for dental patients. CONCLUSIONS: This study showed that a relationship between dental anxiety and psychological distress exists. It would be an improvement to use a short questionnaire like the Dental Anxiety Scale to evaluate a patient before his first treatment so that more appropriate treatments can be pursued.

Dental anxiety in patients attending a student dental clinic.

BACKGROUND: This study investigated the expectations and experiences of a sample of new patients visiting an Australian regional university Student Dental Clinic with regard to anxiety provoking and alleviating stimuli in the clinical environment. Differences in anxiety levels were examined by age, gender and the type of procedure undergone. METHODS: The number of dental patients who participated in the study was 102 (56 males, 43 females). The study used a pre-treatment/post-treatment design to assess the effect of the dental procedure on anxiety levels of patients. The Modified Dental Anxiety Scale (MDAS) was used to measure anxiety levels in patients at pre-treatment. Questions were also asked about factors which may increase (length of the appointment, invasiveness of procedure) or decrease (perceived student interpersonal skills and clinical ability) dental fear. RESULTS: Females reported higher total MDAS scores (M = 11.93) compared to males (M = 9.94). Younger patients (M = 12.15) had higher dental anxiety than older patients (M = 9.34). There was a reduction in dental anxiety from pre-treatment (M = 1.92) to post-treatment (M = 1.23) on the single item anxiety measure though most of the treatment being undergone by patients was for less complex procedures. CONCLUSIONS: Patients' anticipatory experience of anxiety was higher than the anxiety experience after having undergone treatment at the student dental clinic. Student interpersonal skills and clinical ability as perceived by the patient can lessen dental anxiety in patients. Clinical Supervisor-student ratios need to be more equivalent in order to reduce the time length of appointments which currently are associated with increased patient anxiety levels in student dental clinics.

Community Health Centre-Based Outreach Clinic for undergraduate dental education: Experience in Helsinki over 8 years.

INTRODUCTION: The University Dental Clinic of the City of Helsinki (UDC) developed a Community Health Centre-Based Outreach Clinic, with emphasis on paediatric dentistry. This study aimed to summarise the experiences and explore the student perspectives of the health centre-based outreach teaching clinic. METHODS: The study data were from the years 2010 to 2016. The dental procedures carried out by the third- to fifth-year dental students were based on electronic health record of patients. The students' self-perceived benefits and free-text comments on the outreach training were collected as part of a yearly questionnaire survey. RESULTS: A vast majority of the paediatric dental procedures that are required for competencies of dental students were performed in the outreach clinic. The most common procedures were fillings with local anaesthesia followed by preventive procedures. The majority of the students were very motivated to participate in the outreach training and reported that it was a useful educational approach to broaden their understanding of oral diseases and clinical experience. CONCLUSION: The outreach clinic gives dental students a chance to gain valuable clinical experience through the number and diversity of the dental procedures they carry out. They gain confidence and get an opportunity to get acquainted with the primary healthcare system and social determinants of oral diseases. Outreach appears to provide complementary clinical experiences that fulfil learning outcomes. Learning objectives should be taken into account when planning the outreach programme in order to offer meaningful and motivating education.

Sterilization and Biologic Monitoring in Private Dental Clinics in Lebanon.

AIM: The aim of the present study was to evaluate sterilization practices and effectiveness in the Lebanese private dental sector and identify potential factors contributing to sterilization failure. MATERIALS AND METHODS: A 13-item questionnaire consisting of four demographic/professional questions and nine questions related to sterilization practices along with self-contained biologic indicators (SCBIs) were delivered to a representative sample of Lebanese private offices. Univariate statistics and bivariate analyses were performed to compare sterilization failure rates according to demographic, professional, and sterilization-related conditions. RESULTS: Out of the 560 dentists contacted, 205 dentists returned the completed questionnaires and undamaged processed SCBIs. The tested autoclaves (n = 134) were mostly dynamic air removal (69.4%) and had a mean age of 10.5 ± 6.9 years. The dry heat ovens (n = 71) were all static air and had 12.9 ± 8.1 years. The dental assistants performed the routine sterilization procedures in nearly 62% of the practices and sterilization cycles were run 4 to 6 times per week in 75% of the offices. Correct temperature/time ratios were applied in 97% of the autoclaves and 80.3% of the ovens. Few dental practices reported having preventive maintenance (17.9% for the autoclaves and 14.1% for the ovens). Routine monitoring of sterilizer efficacy was infrequently performed and was mostly conducted using physical indicators. Sterilization failure rate was higher for the ovens (16.9%) than for the autoclaves (7.5%). Incorrect temperature/time ratio was the main significant factor associated with sterilization failures. CONCLUSION: The present study demonstrated a relatively high rate of sterilization failures in the Lebanese private dental sector and identified the human error in setting sterilization cycle parameters as the predominant cause of failure. These findings should prompt actions toward increasing knowledge of the sterilization processes and their monitoring among dental professionals and improving the quality control of sterilization through collaborative efforts among health authorities, dental schools, and associations. CLINICAL SIGNIFICANCE: This study presents the first published data relative to sterilization practices and effectiveness in private Lebanese dental offices and provides a rationale to implement biologic monitoring protocols in Lebanon as long practiced in developed countries.

Relationship between Dental Procedures and Shunt Infections in Hydrocephalic Patients: A Narrative Review.

Oral physicians frequently encounter medically compromised patients in their everyday practice and a sizable number of these patients are in urgent need of specialized care. One such medically specialized category is that of patients suffering from hydrocephalus. A large number of medical reports and citations in support of surgical care of the hydrocephalic disorder are available in literature. However, reports on dental studies offer contradictory statements on the relationship between hydrocephalic shunts and oral manoeuvres. The present narrative review aims to delineate the historical journey of the association between shunt infections and dental procedures, decode the existing controversies and provide updated information on antibiotic prophylaxis prior dental treatment for hydrocephalic patients.

Early Screening of Diabetes and Hypertension in Primary Care Dental Clinics at King Saud University in Riyadh, Kingdom of Saudi Arabia.

INTRODUCTION: Diabetes mellitus and hypertension are the leading chronic diseases in Saudi Arabia; 23.1% of the Saudi population are diabetic and 25.5% are hypertensive. This cross-sectional study was made on dental setting to determine the effectiveness of screening of diabetes and hypertension in dental clinics. MATERIALS AND METHODS: This study was carried out in the primary care dental clinics at the Dental College in King Saud University in Riyadh, Saudi Arabia. Before starting any treatment, a face-to-face interview was administered to collect a brief medical history and personal data followed by measurement of body mass index (BMI). After that, blood pressure level reading was obtained using electrical sphygmomanometer. Finally, a glucose level reading was obtained from capillary blood from the patient's third fingertip using glucose reader. RESULTS: Our study included 283 participants, 118 of whom were females (41.7%). Our study showed that a significant amount of the participants are at risk of having hypertension (44.8%). In addition, a significant number (10.2%) of the participants are at risk of having diabetes. Furthermore, 35.7% of the sample had obesity as a risk factor for diabetes and hypertension. CONCLUSION: The dental team can play an important role in screening of diabetes, hypertension, and other chronic diseases. In Saudi Arabia, public awareness of the chronic diseases is still critically insufficient. CLINICAL SIGNIFICANCE: Our study showed the importance of the screening even for patients with negative history of diabetes or hypertension.

Relationship between xerostomia and psychotropic drugs in patients with schizophrenia: evaluation using an oral moisture meter.

WHAT IS KNOWN AND OBJECTIVE: Patients with schizophrenia are most commonly treated with antipsychotic medications, often with the addition of anxiolytics. This study used an oral moisture meter to evaluate xerostomia in patients with schizophrenia taking typical and atypical antipsychotics, anxiolytics and non-psychotropic medications. METHODS: Patients diagnosed with schizophrenia according to ICD-10 criteria in the Department of Psychiatry, Kitasato University East, and affiliated hospitals were studied. All patients were on psychotropic medications. Patients with diseases associated with xerostomia, such as Sjögren's syndrome I, were excluded. RESULTS AND DISCUSSION: A total of 127 patients were enrolled. Mean oral moisture was 27·81 ± 2·27% (normal, ≥30·0%). A significant association was observed between objective oral moisture and the subjective sense of dry mouth. Multivariate analysis revealed a negative correlation between the number of antipsychotics and, especially, anxiolytics, and the degree of oral moisture. Drug dosages themselves were not significantly correlated with dry mouth. These findings suggest that objective oral moisture measurements show decreased moisture in patients on these medications and that the degree of moisture shows a greater negative correlation with the number, as opposed to the dosages, of psychotropic drugs administered. WHAT IS NEW AND CONCLUSIONS: When patients with schizophrenia visit a dental clinic, it is important for the dentist to accurately assess the degree of oral moisture and to determine the medications being taken. Based on these findings of the association of polypharmacy with xerostomia, dentists are encouraged to inform the psychiatrist of the need to actively manage patients' xerostomia.
