Biomechanical and Physical Characteristics of Dental Dam Sheets Used for Absolute Isolation.

This study aimed to evaluate the mechanical and physical properties of dental dam sheets used for absolute isolation and to correlate the mechanical parameters with cost. Twenty-one dental dam sheets were tested: ALLPRIME; Madeitex; Sanctuary non-latex, Sanctuary latex black, green, and blue; Nic Tone blue and black; Mk Life; Elastidam; Bassi; Pribanic; Care; OK; MDCDental; Keystone; Dura Dam; Flexidam; Sanctuary blue; Nic Tone blue; Ehros; and USE. The thicknesses of the dental dam sheets were measured using a digital micrometer (Mitutoyo). The dental dam sheets (n=15) were prepared by cutting the samples with dimensions of 80 × 10 mm with a 1.7 mm hole made at the center of each specimen, following the ISO 9001 standard. The specimens were tested using a universal testing machine (Emic) at a speed of 500 mm/min until rupture to calculate rupture force (RF, N), elongation (%), and ultimate tensile strength (UTS, MPa), their thickness (mm) was measured using a digital micrometer, and scanning electron microscopy and X-ray energy dispersive spectroscopy were performed to analyze the structure and composition. The radiopacity was measured using digital radiography. Thickness, UTS, RF, and elongation data were analyzed by one-way ANOVA and Tukey's test (α=0.05). The Flexidam dental dam had the largest thickness (0.5 mm), while Nic Tone had a median thickness of 0.3 mm; the RF value (41.3 N) was higher for the thicker dental dams. The other dental dams had RF values ranging from 19 to 30 N. The highest elongation was obtained for the non-latex Sanctuary dental dam (600 mm). The Bassi dental dam had the highest UTS value (15 MPa), and medium and small particles were observed in most of the gums. A loss of continuity was detected in the structure of Sanctuary green and blue media. The predominant elements in the sheets were carbon, magnesium, sulfur, silicon, and calcium. The UTS, RF, and elongation varied substantially, indicating insufficient standardization of dental dam sheets. Nonetheless, most of the tested dental dams exhibited mechanical and physical properties suitable for clinical use. The correlation between the cost and mechanical properties of the dental dams was very low.

A Novel Isolation Technique Using Polytetrafluoroethylene Tape and Split Dam Isolation for Cementation in Bridge Restorations.

This case report presents a novel technique for bridge restoration using polytetrafluoroethylene (PTFE) tape and split dam isolation in situations where achieving complete dental dam isolation is challenging. Achieving high-quality isolation by controlling gingival crevicular fluid and intraoral relative humidity is important during cementation. However, an improved technique during bridge restoration is needed due to the difficulties faced with dental dam isolation. A porcelain fused to zirconia bridge extending from the maxillary canine to the first molar was used to demonstrate the novel restoration technique in this case report. Split dam isolation lowers the relative humidity in the oral cavity, and PTFE blocks the gingival crevicular fluid. The effects of combining PTFE tape with split dam isolation on isolation (controlling crevicular fluid, saliva, and relative humidity in the operative field) were similar to those obtained with dental dam isolation and made for easier removal of excess cement. The novel technique introduced in this case report can enhance isolation quality during bridge restoration.

Understanding Risk Factors for Oropharyngeal Gonorrhea Among Sex Workers Attending Sexual Health Clinics in 2 Australian Cities: Mixed Methods Study.

The risk factors for oropharyngeal gonorrhea have not been examined in sex workers despite the increasing prevalence of gonorrhea infection. This study aims to determine the risk factors for oropharyngeal gonorrhea in female and gender-diverse sex workers (including cisgender and transgender women, nonbinary and gender fluid sex workers, and those with a different identity) and examine kissing, oral sex, and mouthwash practices with clients. This mixed methods case-control study was conducted from 2018 to 2020 at 2 sexual health clinics in Melbourne, Victoria, and Sydney, New South Wales, Australia. We recruited 83 sex workers diagnosed with oropharyngeal gonorrhea (cases) and 581 sex workers without (controls). Semistructured interviews with 19 sex workers from Melbourne were conducted. In the case-control study, the median age of 664 sex workers was 30 (IQR 25-36) years. Almost 30% of sex workers (192/664, 28.9%) reported performing condomless fellatio on clients. Performing condomless fellatio with clients was the only behavior associated with oropharyngeal gonorrhea (adjusted odds ratio 3.6, 95% CI 1.7-7.6; P=.001). Most participants (521/664, 78.5%) used mouthwash frequently. In the qualitative study, almost all sex workers reported kissing clients due to demand and generally reported following clients' lead with regard to kissing style and duration. However, they used condoms for fellatio because they considered it a risky practice for contracting sexually transmitted infections, unlike cunnilingus without a dental dam. Our study shows that condomless fellatio is a risk factor for oropharyngeal gonorrhea among sex workers despite most sex workers using condoms with their clients for fellatio. Novel interventions, particularly targeting the oropharynx, will be required for oropharyngeal gonorrhea prevention.

Delay discounting of protected sex and compulsive sexual behavior in women withborderline personality disorder.

Borderline personality disorder (BPD) is a complex mental health condition characterized by emotional dysregulation, impulsivity, and unstable interpersonal relationships. Some individuals with BPD regularly engage in sexual risk behavior such as unprotected sex and are at higher risk of contracting sexually transmitted infections. This study investigates discounting of condom- or dental dam-protected sex in women with BPD compared with a control group. Data were collected from 40 women diagnosed with BPD and 40 healthy controls with an average age of 27.28 years (SD = 6.14) using the Sexual Delay Discounting Task (SDT), the Borderline Symptom List-23 (BSL-23), and the Compulsive Sexual Behavior Disorder Scale-19 (CSBD-19). Women with BPD were less likely to use an immediately available condom or dental dam and more likely to discount safer sex than controls. Partner desirability and the perceived STI risk influenced the participants' likelihood of having protected sex. Women with BPD showed more symptoms of compulsive sexual behavior (CSB) than controls. However, sexual delay discounting was not significantly correlated with borderline symptoms or CSB in the BPD group. These findings contribute to our understanding of sexual impulsivity in women with BPD and highlight the omission and delayed availability of safety measures as important contributors to sexual risk behavior and STI risk in women. Impulsive sexual behavior, as well as the accompanying sexual health concerns, should receive special attention in the treatment of women with BPD.

YouTube as a source of information about rubber dam: quality and content analysis.

This study aimed to evaluate the content, quality and demographics of YouTube videos about rubber dam as an information source for clinicians and dental students. "Rubber dam," "rubber dam application," "dental isolation," "rubber dam isolation," and "dental dam" were determined as keywords for the detection of YouTube videos related to rubber dam. Seventy 3 videos were evaluated and a total of 34 videos met the inclusion criteria. All selected videos were evaluated according to 8 parameters. The videos were scored 1 if the videos contained information about the selected parameter, but if the videos did not contain enough information, they were scored 0. The data were statistically analyzed with the analysis of variance and post hoc Tukey test (p < 0.05). We found that 41% of the videos have poor, 47% have moderate, and 12% have good information. There is a statistically significant difference in time between poor and good information content (p < 0.05). There is a statistically significant difference between the poor and good information in the video information and quality index 1. Rubber dam-related videos available on YouTube are generally moderately informed and insufficient. YouTube is currently not sufficient as a source of information for patients and clinicians at the moment. The YouTube platform should be developed and enriched with quality information on current and dental issues.

Global survey of endodontic practice and adoption of newer technologies.

To investigate current endodontic practices, adoption of technologies and continuing education attendance within specialist endodontic practice globally and to identify geographic trends. A web-based survey of endodontic association members in Australia, Britain, Canada, Italy, New Zealand and the USA on routine treatment preferences, armamentarium and education attendance was conducted. Chi-squared, independent sample t-tests, Cochran's Q test and McNemar's test were performed. The survey was completed by 543 endodontists or endodontic post-graduate students. Almost all respondents used the dental operating microscope (DOM, 91.3%), engine-driven nickel-titanium instruments (NiTi, 97.6%), electronic apex locators (EAL, 93.0%), cone-beam computed tomography (CBCT, 91.2%) and calcium silicate-based materials (CSBMs, 93.7%). Dental dam was always used by 99.1%. Over half used irrigation adjuncts (81.8%), warm vertical compaction (74.6%) and heat-treated NiTi (60.2%). Geographic comparison between AP (Asia-Pacific, n = 78), AM (Americas, n = 402) and EM (Europe and Middle East, n = 63) was performed. AM and EM preferred single-visit treatment more (p < .001) and used higher sodium hypochlorite concentrations than AP. AM had more access to CBCT in the workplace (86.6%) than AP (65.4%, p < .001) and used CBCT for routine preoperative assessment (39.6%) more than EM (7.3%, p < .001). Almost all of EM used irrigation adjuncts (95.2%), more than AM (78.1%, p = .001). AP used steroid/antibiotic medicaments most (p < .001) and had the highest attendance at continuing education programmes. Several endodontic-specific armamentaria have reached almost complete adoption within global specialist endodontic practice, whilst the continued uptake of newer technologies should be followed over time. Some practising philosophies varied significantly across different geographic regions.

Understanding the relationship between casual substance use and sexual risk behaviors in sexual and gender minority emerging adults

Research has shown the heightened risk for sexually transmitted infections (STIs), sexual risk behavior, and substance use in sexual and gender minority (SGM) individuals. Further research is necessary to understand understudied sexual risk behaviors in a sample of casual substance users as the implications of substance use are not just experienced by individuals with substance use disorders. Many emerging adults (ages 18-29) experiment with substance use during the transition from adolescence to adulthood and the relationship with sexual risk behaviors are important to understand in this population. Data were collected online through Prolific from 75 participants between the ages of 18-29 who identified as being a SGM. Participants completed a survey in March 2020 indicating their substance use. In November 2021, participants indicated their risky sexual behaviors. A path analysis indicated that cannabis use at Time 1 was significantly associated with greater oral sex without a condom or dental dam, sex under the influence of alcohol and other substances at Time 2. Cocaine use at Time 1 was significantly associated with increased sex under the influence of alcohol and sex with a stranger. Results illustrate long-term implications of casual substance use in SGM populations and highlights understudied sexual risk behaviors.

Current endodontic practice and use of newer technologies in Australia and New Zealand.

This study investigated endodontic clinical preferences, adoption of newer technologies and information sources among dentists and endodontists. Dental and endodontic society members in Australia and New Zealand were surveyed online regarding their endodontic treatment preferences, armamentarium, information sources and continuing professional education (CPE) attendance. Complete responses were received from 71 endodontic specialists or postgraduates (Group E) and 139 general dentists (Group D). Most of Group E used dental operating microscopes (95.8%), endodontic cone-beam computed tomography (CBCT; 98.6%) and calcium silicate-based materials (CSBMs; 97.2%), significantly more (P < 0.001) than Group D (86.3% used loupes, <32% used CBCT for endodontics or CSBMs). Most respondents used dental dam always for endodontics (94.3%), electronic apex locators (EAL; 81.0%) and engine-driven nickel-titanium (NiTi) instruments (91.4%); Group E had more experience with engine-driven NiTi (P < 0.001). Endodontic CPE attendance was highest at dental association programs (P < 0.001) while hands-on NiTi training attendance was highest via commercial companies (P < 0.05). Online information sources were commonly used (38.8% of Group D, 59.2% of Group E). Dental dam, EAL and engine-driven NiTi were almost universally used. The endodontic group reported high adoption of newer endodontic technologies. Endodontic CPE and information sources should be further surveyed as online engagement evolves. © 2023 Australian Dental Association.

Experiences with Cling Film and Dental Dam Use in Oral Sex: A Mixed-Methods Systematic Review

This study aimed to conduct a mixed-methods SR of the literature investigating the experiences (knowledge, attitudes, practices, and effects of use) concerning dental dam and cling film use. The SR methodology was informed by the Preferred Reporting Items for SRs and Meta-analysis framework, the Cochrane Handbook for SR of Interventions, the Joanna Briggs Institute guideline for conducting mixed-methods SRs, and the PICO (population, intervention (or exposure), comparison, and outcome) framework. Using a set of inclusion criteria, relevant studies in the literature were obtained for the review from 11 electronic databases, Teesside University Library, websites of multilateral health organisations, and reference lists of eligible literature. The included literature was appraised for quality using the Mixed Methods Appraisal Tool version 2018 and the AAOCDS Tool. Only those studies in the literature with sufficient quality were finally included for data extraction (using an adapted version of the JBI Quality Assessment and Review Instruments) and synthesis. Best evidence synthesis was performed for the quantitative data, while meta-aggregation was performed for the qualitative data. The synthesised data were then configured using the segregated approach. A total of 529 studies from the literature were obtained from the searched databases, while only four were obtained from the other sources. After de-duplication, screening, and quality appraisal, a total of 17 studies were found eligible and included in this review. Sixteen studies were non-grey literature while, one was grey literature, and only a few reported a finding on cling film and heterosexual populations. A total of 5516 adolescents and adults were investigated in the analysed literature. Overall, the reported knowledge of dental dams was generally poor, while no study reported knowledge of cling film. The attitudes towards dental dams/cling film were complex and predominantly negative, with very few participants using dental dams/cling film for oral sex. No study reported any finding on the effect(s) of dental dam/cling film use. In conclusion, there is a need for robust and strategic public health interventions for sexual health and safer oral sex practices.

Mitigation of COVID-19 During Dental Treatment in a State Prison System.

In congregate living settings when active coronavirus disease 2019 (COVID-19) transmission is present, limiting the scope of dental care to urgent and emergent treatment minimizes exposure risk for patients and staff. Engineering controls to mitigate aerosol production during dental procedures, including enhanced high-volume evacuation, high-efficiency particulate absorbing air filtration, and the use of a dental dam provide additional protection for dental providers and staff. Properly fitted N-95 respirators are of particular importance to limit COVID-19 transmission when SARS-CoV-2 containing aerosols may be present. When patients are known to be COVID-19 positive, the use of powered air-purifying respirators is appropriate. Further protection against the spread of disease among patients and staff may be provided by point-of-care testing for patients prior to dental procedures during outbreaks.

Online Questionnaire-Based Study to Evaluate the Attitudes and Use of Rubber Dental Dams by Saudi Dental Practitioners.

BACKGROUND A dental dam is a protective sheet with an aperture and is used to prevent the spread of infection during dental procedures. This study aimed to use a 2-part online questionnaire to evaluate the attitudes and use of rubber dental dams by 300 Saudi dental interns, general dental practitioners, residents, specialists, and consultants in prosthodontics, endodontics, and restorative dentistry. MATERIAL AND METHODS The 17-item validated questionnaire consisted of 5 questions on demographics, 2 on knowledge, 6 on attitudes, and 4 on perceptions. It was distributed through Google Forms. The chi-square test was used to determine the associations between the study variables and perception questions. RESULTS A total of 41.67% participants were specialists/consultants, among which 59.2% were in the prosthodontics specialty, 12.8% in endodontics, and 28% in restorative dentistry. Most participants (84.67%) stated the necessity of using rubber dams during post and core procedures. A total of 53.67% had received enough training for using rubber dams during their undergraduate/residency education. The majority of participants (41%) also preferred using rubber dams during the prefabricated post and core procedures, and 28.33% stated that the remaining tooth structure was one of the major reasons for not using rubber dams during the post and core procedures. CONCLUSIONS Workshops and hands-on training should be conducted among dental graduates to instill a positive attitude regarding the use of rubber dams.

The potential ‘blue light hazard’ from LED headlamps

Many dental personnel use light-emitting diode (LED) headlamps for hours every day. The potential retinal ‘blue light hazard’ from these white light headlamps is unknown. MethodsThe spectral radiant powers received from direct and indirect viewing of an electronic tablet, an LED curing light, a halogen headlamp, and 6 brands of LED headlamps were measured using integrating spheres attached to fiberoptic spectroradiometers. The spectral radiant powers were measured both directly and indirectly at a 35 cm distance, and the maximum daily exposure times (tMAX) were calculated from the blue weighted irradiance values. ResultsThe headlamps emitted very different radiant powers, emission spectra, and color temperatures (K). The total powers emitted at zero distance ranged from 47 mW from the halogen headlamp to 378 mW from the most powerful LED headlamp. The color temperatures from the headlamps ranged from 3098 K to 7253 K. The tMAX exposure times in an 8 h day when the headlamps were viewed directly at a distance of 35 cm were: 810 s from the halogen headlamp, 53 to 220 s from the LED headlamps, and 62 s from the LED curing light. Light from the LED headlamps that was reflected back from a white reference tile 35 cm away did not exceed the maximum permissible exposure time for healthy adults. Using a blue dental dam increased the amount of reflected blue light, but tMAX was still greater than 24 h. ConclusionsWhite light LED headlamps emit very different spectra, and they all increase the retinal ‘blue light hazard’ compared to a halogen source. When the headlamps were viewed directly at a distance of 35 cm, the ‘blue light hazard’ from some headlamps was greater than from the LED curing light (tMAX = 62 s). Depending on the headlamp brand, tMAX could be reached after only 53s. The light from the LED headlamps that was reflected back from a white surface that was 35 cm away did not exceed the maximum permissible ocular exposure limits for healthy adults. Clinical relevanceReflected white light from dental headlamps does not pose a blue light hazard for healthy adults. Direct viewing may be hazardous, but the hazard can be prevented by using the appropriate blue-light blocking glasses.

HIV and STI Prevention Among Spanish Women Who have Sex with Women: Factors Associated with Dental Dam and Condom Use

The scientific community has systematically ignored the needs of women who have sex with women (WSW). The invisibilization of romantic and sexual relationships between women has caused a profound lack of knowledge about the impact of HIV and other STIs on this population subgroup. This study aims to analyze the frequency of dental dam and condom use in WSW and identify the variables that explain the use of these two preventive methods. The sample is composed of 327 women aged between 18 and 60 years (M = 27.82; SD = 8.10). The results indicate that only 4.7% of those who practice cunnilingus and 5.2% of those who practice anilingus report “always” using dental dam (systematic use). Condoms are used systematically by 37.1% of those who practice vaginal penetration and 37.8% of those who practice anal penetration. Age, high perceived self-efficacy, and adequate assertive communication skills are variables significantly related to preventive behavior. The severity attributed to HIV and the perceived risk of infection are protective factors regarding dental dam use. For condom use, high levels of internalized homophobia and drug use are risk factors. Future preventive strategies should provide information on preventive strategies to WSW who, for different reasons, are not involved in LGBT contexts or associations and, therefore, do not have access to training activities and mistakenly believe that they are invulnerable as they do not have sexual relations with men.

Efficacy of a new membrane obturator prosthesis in terms of speech, swallowing, and the quality of life of patients with acquired soft palate defects: study protocol of the VELOMEMBRANE randomized crossover trial

BackgroundSoft palate defects created during oral cancer surgery may prevent complete palatal closure and trigger palatopharyngeal insufficiency. One current treatment employs a rigid obturator prosthesis; an extension of acrylic resin at the level of the hard palate ensures surface contact with the remaining musculature. Unfortunately, airflow escape often causes hypernasality, compromises speech intelligibility, and creates swallowing problems (including leakage of food and fluid into the nasal airway). We plan to test a new removable denture featuring a thick dental dam that serves as a membrane obturator. The principal objective of the clinical trial is a comparison of speech handicap levels after 1 month in patients with acquired velar insufficiencies who wear either the new device or a conventional, rigid obturator. The secondary objectives are between-device comparisons of the swallowing handicaps and the health-related qualities of life.MethodsThe VELOMEMBRANE trial is a superiority, open-labeled, two-way, random crossover clinical trial. Adult patients exhibiting velar or palatovelar substance loss after tumor excision and who are indicated for rigid obturator-mediated prosthetic rehabilitation will be recruited in two teaching hospitals in France. Fourteen participants will be randomly allocated to wear both prostheses for 1-month periods in either order. The new membrane obturator is a removable resin prosthesis incorporating a rigid extension that holds a dental dam to restore the soft palate. The primary outcome will be the extent of phonation-related disability (the overall score on the Voice Handicap Index [VHI]). The secondary outcomes will be the Deglutition Handicap Index and health-related quality of life scores of the European Organization for Research and Treatment of Cancer (EORTC).DiscussionHigh-quality evidence will be provided to document the utility of a new medical device that may greatly improve the management and quality of life of patients with acquired velar insufficiency.Trial registrationClinicalTrials.govNCT04009811.

Vital Pulp Therapy in Permanent Teeth with Irreversible Pulpitis Caused by Caries: A Prospective Cohort Study.

Background: When a tooth is diagnosed with irreversible pulpitis, root canal therapy (RCT) is generally performed to completely remove pulp tissue, which might lead to a higher risk of loss of vascularity, and teeth being more prone to fracture. Vital pulp therapy (VPT) is a personalized method of treating irreversible pulpitis, which conforms to the trend of minimally invasive endodontics. The remaining vital pulp could promote the physiological development of the roots of young permanent teeth with incomplete apical foramen. However, clear guidelines for VPT indication are still missing. Objective: This prospective cohort study evaluated the outcomes of vital pulp therapy (VPT) using iRoot BP Plus (Innovative Bioceramix Inc, Vancouver, BC, Canada) in permanent teeth of 6- to 20-year-old patients with irreversible pulpitis caused by caries and analyzed the preoperative factors affecting VPT prognosis. Methods: Fifty-nine permanent teeth in 59 patients with irreversible pulpitis caused by caries were treated with VPT using iRoot BP Plus. All patients received VPT under a standardized protocol. After informed consent, teeth were isolated with a dental dam, then operators performed VPT with iRoot BP Plus and restored the teeth with composite resin or stainless steel crown. Patients were postoperatively recalled after 3, 6 and 12 months and then recalled annually. Successful cases were defined as successful in both clinical and radiographic evaluations. A statistical analysis was performed using the Fisher exact test, and the level of significant difference was p < 0.05. Results: After 6–36 months of follow-up, a total of 57 teeth from 57 patients were accessible for evaluation. The mean age of subjects was 11.75 ± 3.81 years. The overall clinical and radiographic success rate of VPT was 91.2% (52/57). With an observation time of one year or more, the success rate was 90.5% (38/42). All the symptoms and physical examination findings showed no significant effect on VPT prognosis (p > 0.05) using a binary logistic regression model. Conclusions: Permanent teeth in 6- to 20-year-old patients diagnosed as irreversible pulpitis caused by caries can be successfully treated with VPT using iRoot BP Plus.

The use of latex and non-latex gloves and dental equipment in UK and Irish dental hospitals.

Aim To identify glove usage within UK and Ireland dental hospitals as well as the use of latex- and non-latex-containing dental equipment.Method A self-completed questionnaire was disseminated to 16 dental hospitals in the summer of 2017. The survey concerned their current use of latex and non-latex gloves and dental equipment. In addition, information was sought regarding any problems associated with non-latex and latex gloves.Results The questionnaire response rate was 13/16 (81%), of which 100% reported the use of non-latex examination gloves. The majority were using nitrile gloves. Twelve of the 13 dental hospitals would use examination gloves for simple extractions and 11 would use sterile gloves for minor oral surgery. In ten hospitals (77%), the sterile gloves were always non-latex, and again, the majority were nitrile. Latex-containing dental equipment including orthodontic bands, prophylactic polishing cups and dental dam was still being used within some dental hospitals, but to a much lesser extent than non-latex.Conclusion All dental hospitals were using latex-free examination gloves and were showing a move towards latex-free dental equipment. This usage is comparable to what has been seen in general dental practice and follows the trend towards latex-free dentistry.

Behavior of Children during Dental Care with Rubber Dam Isolation: A Randomized Controlled Study.

Background: The establishment of the dental dam improves dentist working conditions and patient protection. The purpose of this study was to analyze the behavior of the child during dental care with or without a dam. Methods: In this interventional randomized study, 51 patients are divided into two groups, one with a rubber dam and the other with cotton roll isolation. Their behavior was observed during the treatment of temporary molars. The duration of the treatment, the patient’s feeling with a visual analogue scale (VAS), the behavior (B) of the child measured with a hetero-evaluation scale (modified Venham scale) and the cardiac frequency (CF) were measured. Results: The group treated with a rubber dam has a significant decrease in the various stress parameters that have been identified (B, p value = 0.034; CF, p value = 0.015). Subgroups of patients with and without nitrous oxide sedation were compared and similar results were obtained. Conclusions: Isolation with a rubber dam reduces child’s stress during dental care. Although it is slightly more time-consuming and training is necessary for a quick and effective placement, it allows dentists to perform dental care in the best possible conditions, while reducing dental anxiety in young patients.

Digital scan over dental dam: workflow for successful clinical outcome.

Although the use of intraoral scanners is becoming more popular, dental professionals are still presented with the challenge of obtaining precise imaging of the preparation margins. Deep preparation margins, saliva contamination, or bleeding during the scanning procedures can impair the accuracy of the digital scan. Dental dam placement can significantly improve the quality and efficiency of the digital scan, while simultaneously providing a clean restorative field and serving as a barrier to the spread of infections for the protection of dental professionals. This article describes a technique of intraoral scanning by using dental dam isolation to ensure maximum accuracy of the digital scan of the dental preparations.
