Comparison of risk assessment based on clinical judgement and Cariogram in addition to patient perceived treatment need

Determinants of Clinical Decision Making under Uncertainty in Dentistry: A Scoping Review

Clinical decision-making for diagnosing and treating oral and dental diseases consolidates multiple sources of complex information, yet individual clinical judgements are often made intuitively on limited heuristics to simplify decision making, which may lead to errors harmful to patients. This study aimed at systematically evaluating dental practitioners’ clinical decision-making processes during diagnosis and treatment planning under uncertainty. A scoping review was chosen as the optimal study design due to the heterogeneity and complexity of the topic. Key terms and a search strategy were defined, and the articles published in the repository of the National Library of Medicine (MEDLINE/PubMed) were searched, selected, and analysed in accordance with PRISMA-ScR guidelines. Of the 478 studies returned, 64 relevant articles were included in the qualitative synthesis. Studies that were included were based in 27 countries, with the majority from the UK and USA. Articles were dated from 1991 to 2022, with all being observational studies except four, which were experimental studies. Six major recurring themes were identified: clinical factors, clinical experience, patient preferences and perceptions, heuristics and biases, artificial intelligence and informatics, and existing guidelines. These results suggest that inconsistency in treatment recommendations is a real possibility and despite great advancements in dental science, evidence-based practice is but one of a multitude of complex determinants driving clinical decision making in dentistry. In conclusion, clinical decisions, particularly those made individually by a dental practitioner, are potentially prone to sub-optimal treatment and poorer patient outcomes.

Developing and testing a prediction model for periodontal disease using machine learning and big electronic dental record data

Despite advances in periodontal disease (PD) research and periodontal treatments, 42% of the US population suffer from periodontitis. PD can be prevented if high-risk patients are identified early to provide preventive care. Prediction models can help assess risk for PD before initiation and progression; nevertheless, utilization of existing PD prediction models is seldom because of their suboptimal performance. This study aims to develop and test the PD prediction model using machine learning (ML) and electronic dental record (EDR) data that could provide large sample sizes and up-to-date information. A cohort of 27,138 dental patients and grouped PD diagnoses into: healthy control, mild PD, and severe PD was generated. The ML model (XGBoost) was trained (80% training data) and tested (20% testing data) with a total of 74 features extracted from the EDR. We used a five-fold cross-validation strategy to identify the optimal hyperparameters of the model for this one-vs.-all multi-class classification task. Our prediction model differentiated healthy patients vs. mild PD cases and mild PD vs. severe PD cases with an average area under the curve of 0.72. New associations and features compared to existing models were identified that include patient-level factors such as patient anxiety, chewing problems, speaking trouble, teeth grinding, alcohol consumption, injury to teeth, presence of removable partial dentures, self-image, recreational drugs (Heroin and Marijuana), medications affecting periodontium, and medical conditions such as osteoporosis, cancer, neurological conditions, infectious diseases, endocrine conditions, cardiovascular diseases, and gastroenterology conditions. This pilot study demonstrated promising results in predicting the risk of PD using ML and EDR data. The model may provide new information to the clinicians about the PD risks and the factors responsible for the disease progression to take preventive approaches. Further studies are warned to evaluate the prediction model's performance on the external dataset and determine its usability in clinical settings.

The Influence of Preventive Regimens Containing Different Toothpastes on Caries Risk of High-Risk Patients: A Randomized Clinical Trial

BACKGROUND: The main objective of conservative dentistry is maintaining the health of the dentition and restored teeth free from dental caries. The prevention of dental caries can be achieved by personal prevention programs at home, dental health care professional, and public health application programs. Based on knowledge related to the etiology and pathogenesis of dental caries, this provides a chance for application of effective prevention program for the prevention of dental caries. AIM: This study aimed to evaluate the effect of different preventive regimens using different toothpastes on caries risk using cariogram and decayed, missing, and filled (DMF) scores of high caries risk patients. MATERIALS AND METHODS: The study was conducted on 66 participants with high caries risk. Participants were divided into three groups, 22 participant each. According to the test regimen, where (A1) participants were exposed to a regimen including dual zinc plus arginine-based toothpaste (Colgate total), (A2) participants were exposed to a regimen including zinc-based toothpaste (Crest complete), and (A3) control group was participants that were exposed to a regimen including fluoride-based toothpaste (Signal). The study was carried for 1 year, assessment of cariogram and DMF scores was done in four intervals: T0: baseline, T3: after 3 months, T6: after 6 months, and T12: after 12 months. RESULTS: According to cariogram, there was a statistically significant difference between Groups A1, A2, and A3, where p < 0.001. However, DMF scores of all groups showed no statistically significant difference between the three groups. CONCLUSIONS: Dual zinc plus arginine-based toothpaste is a superior caries preventive regimen in high caries risk patients. CLINICAL SIGNIFICANCE: The benefits of preventive regimen to the practitioner will be providing a non-invasive, and cost-efficient method to prevent dental caries. Benefits to the patient will be an improvement of oral hygiene, prevention of dental caries, and maintain healthy dental supporting structures.

Maintaining Clinical Freedom Whilst Achieving Value in Biologics Prescribing: An Integrated Cross-Specialty Consensus of UK Dermatologists, Rheumatologists and Gastroenterologists

BACKGROUND

Biologics are now key drugs in the management of immune-mediated inflammatory diseases. However, the increasingly complex biologics environment and growing cost pressures in the UK have led to variability in drug commissioning and inequity of patient access across regions.

OBJECTIVES

Our objectives were to provide consensus recommendations for enhancing the current situation in biologic prescribing in the UK by balancing clinical freedom with equitable distribution of biologics given the limited availability of resources.

METHODS

A modified Delphi approach was used to reach integrated, cross-specialty consensus among dermatologists, rheumatologists and gastroenterologists practising within the English National Health Service (NHS).

RESULTS

We describe the concepts of clinical freedom and clinical judgement and demonstrate how, together with patient choice, they can be exercised in the context of biologic prescribing in the NHS. We highlight that in England, local variations occur that are at odds with National Institute for Health and Care Excellence (NICE) guidance; these variably limit the degree to which clinicians can exercise clinical freedom and impact on equity of patient access to treatments. We define factors encompassing a drug's value and identify challenges to the measurement and interpretation of this concept, which can raise barriers to the freedom of clinical choice and appropriate prescribing decisions allowing practices of holistic and personalised medicine. Cross-specialty consensus recommendations on ensuring equitable access to biologics in the NHS while protecting appropriate and individualised drug selection for patients are provided. We have also provided strategies for improving physician-commissioner communication to harmonise equity of patient access to biologics across England and improve patient outcomes. Commentary from patient advisory groups indicates that they welcome our exploration that value does not equal cost and agree that there should be an emphasis on shared decision making, which requires the clinician to practice clinical freedom by aligning the patient's needs and preferences with available treatment choices.

CONCLUSIONS

This consensus highlights the need to strike a balance between clinical freedom and short-term cost restrictions to support equitable resource distribution within the English NHS. Consideration of these recommendations may help to harmonise local, regional and national services and balance equity of patient access to biologic treatments with excellence in the NHS.

Self-reported oral and general health related to xerostomia, hyposalivation, and quality of life among caries active younger adults

Objective: The aim was to study prevalence of xerostomia, hyposalivation and quality of life among caries active younger adults.Materials and methods: A questionnaire regarding oral and general health, xerostomia and quality of life was mailed to 134 caries active (CA) and 40 caries inactive (CI) patients, 25-50 years of age (mean age 39.9 ± 6.2 years) treated at a Swedish Public Dental Service clinic, regarding oral and general health, xerostomia and quality of life. Caries data and unstimulated whole salivary flow rates were obtained from dental records.Results: The overall response rate was 69%. Dental records confirmed that CA patients had more decayed teeth over time than CI patients (p < .001). The CA group reported worse oral health (p < .001) and general health (p < .01), more xerostomia (p < .001) and lower salivary flow rate (p < .01) compared to CI patients. Xerostomia was inversely related to unstimulated whole salivary flow rates as well as to oral and general health (p < .01). There were no differences between groups in quality of life.Conclusion: Younger caries active adult patients reported significantly more xerostomia and hyposalivation compared to caries inactive patients. Xerostomia and hyposalivation were inversely related to perceptions of oral and general health, but not to quality of life.

Patient-reported negative experiences related to caries and its treatment among Swedish adult patients

Background

It has been suggested that dental caries should be regarded as a chronic disease as many individuals repeatedly develop new caries lesions. How this is perceived by caries active patients is unclear. The aim of this study was to measure patient-reported attitudes and negative experiences related to caries and dental treatment.

Methods

A questionnaire was mailed to 134 caries active (CA) and 40 caries inactive (CI) adult patients treated at a Swedish public dental service clinic. The questionnaire included items regarding patient-reported oral health; attitudes towards caries and efforts to prevent them; and negative experiences related to caries and dental treatment. Questionnaire data were supplemented with data on caries and caries prophylaxis from patients’ dental records. Exploratory factor analysis was conducted on items related to patients’ perceptions of problems to see whether scales could be created. Experiences, perceptions and dental records of CA and CI patients were compared.

Results

The overall response rate was 69%. Dental records confirmed that CA patients had significantly more decayed teeth per year and a longer period of caries-active time than CI patients. Factor analysis resulted in 3 distinct scales measuring problems related to caries; 1) caries-related information; 2) negative experiences; and 3) negative treatment/staff attitudes. A fourth scale measuring perceived problems related to caries was also created. The CA group reported significantly more problems related to caries and dental treatment, received significantly more caries-related information, and reported significantly more negative treatment experiences compared to CI patients.

Conclusions

Caries prophylaxis methods need to be improved in order to better meet the needs of caries active patients and to create a more positive experience with dental care.
