The validity of laser fluorescence (LF) and near-infrared reflection (NIRR) in detecting early proximal cavities
Clinical Oral Investigations, 2021Co-Authors: Farzaneh Ahrari, Majid Akbari, Melika Mohammadi, Amir Fallahrastegar, Mona Najaf NajafiAbstract:Objectives Diagnosing cavitated proximal lesions is important for therapeutic decisions. This clinical study aimed to determine the validity of laser fluorescence (LF) and near-infrared reflection (NIRR) techniques for detecting early proximal cavities. Materials and methods The study included 43 proximal surfaces in 15 females who had limited radiolucent lesions in their bitewing radiographs. The approximal areas of interest were assessed by DIAGNOdent Pen (LF) and the Proxi interchangeable head of VistaCam iX Intraoral Camera (NIRR). Finally, orthodontic separators were placed in the contact points to provide enough space between the teeth. The sensitivity, specificity, and accuracy of diagnosing cavitated proximal surfaces were calculated for LF and NIRR against direct visual and tactile examination as the reference standard. Results On the basis of the reference standard, 34 surfaces (79.1%) were not cavitated, whereas 9 surfaces (20.9%) were cavitated and in need of restoration. The sensitivity, specificity, and accuracy of LF were 44.4%, 61.8%, and 58%, and those of NIRR were 88.9%, 14.7%, and 30%, respectively. Conclusions The VistaCam iX Proxi was more sensitive and DIAGNOdent Pen was more specific in detection of proximal cavities. However, none of the techniques was accurate enough to be recommended as a sole approach for proximal caries detection. Clinical relevance LF showed an overall superior diagnostic performance to NIRR for diagnosing proximal cavitation in permanent posterior teeth. Within the limitations of this study, neither VistaCam iX Proxi nor DIAGNOdent Pen could be considered a suitable device for diagnosing proximal cavities.

Comparison of diagnostic effects of infrared imaging and bitewing radiography in proximal caries of permanent teeth
Lasers in Medical Science, 2019Co-Authors: Arghavan Tonkaboni, Aida Saffarpour, Ferial Aghapourzangeneh, Mohammad Javad Kharazi FardAbstract:This study aimed to compare the diagnostic efficacy of VistaCam iX Intraoral Camera system using infrared light and bitewing radiography for detection of proximal caries in permanent teeth. This in vitro study was performed on 108 teeth. The proximal surfaces of the teeth were examined for caries using ICDAS II criteria, bitewing radiography, and the Proxi head of VistaCam iX. The teeth were then sectioned and histologically analyzed (gold standard). Data were analyzed using SPSS version 25 via the correlation test at P

Prevalence of dental caries in Early Head Start children as diagnosed using teledentistry.
Pediatric dentistry, 2008Co-Authors: Dorota T. Kopycka-kedzierawski, Christine H Bell, Ronald J. BillingsAbstract:Purpose This study's purpose was to assess caries prevalence by means of teledentistry in 12- to 60-month old children enrolled in Early Head Start inner-city child core centers. Methods Images of the primary dentition were obtained by trained telehealth assistants using on Intraoral Camera. Images were entered into a Web-based storage and retrieval program. They were transmitted to a secure, remote-site computer and evaluated by a calibrated pediatric dentist. Results Of 162 children screened, 93 were caries free and 69 had early childhood caries (ECC). Of these, 28 had severe early childhood caries (S-ECC). The mean dfs score for all 162 children was 1.88. The mean dfs score for the 69 ECC children was 4.42. The mean dfs for the subgroup of 28 S-ECC children was 7.61. Caries scores of S-ECC children were statistically significantly different from caries scores of the entire cohort and from caries scores of the ECC children. Conclusions This study's results show that: (1) almost half of the preschoolers enrolled in the study were affected by dental caries; (2) only a few children had ever had a dental visit; and (3) teledentistry offers a potentially efficient means of screening high-risk preschool children for signs of early childhood caries.

Dental screening of preschool children using teledentistry: a feasibility study.
Pediatric dentistry, 2007Co-Authors: Dorota T. Kopycka-kedzierawski, Ronald J. Billings, Kenneth M. McconnochieAbstract:Purpose The purpose of this study was to assess the feasibility and reliability of using Intraoral Cameras and telehealth communication technology to screen preschool children for oral disease, in particular early childhood caries (ECC). Methods The authors used the existing infrastructure of the Health-e-Access telehealth Network to: (1) assess the diagnostic quality of dental images using the Dr. Camscope Intraoral Camera; and (2) compare the resulting images to a traditional oral examination. A calibrated dental examiner observed 50 preschool children 4 to 6 years old who were enrolled in an inner-city childcare center. Following the oral examination, images of the children's teeth were obtained by a trained telehealth assistant and transmitted to the remote site computer; identifiers were removed and the images were randomized. After a 2-week washout period, the images were read by the same examiner. Results A complete set of dental images was obtained from all 50 children in the study. A greater proportion of children examined using the Intraoral Camera were observed to have caries (42%) compared to children examined visually (28%). Furthermore, a greater number of carious teeth were detected from the images than from the visual examinations. The mean teledentistry dfs score was 2.10, and the oral examination 1.50 (P > .05). The kappa agreement was 61 (kappa = 0.61; 95% CI = 039-0.89). Conclusions There was no statistically significant difference between a visual examination and an examination using an Intraoral Camera, thus suggesting that the Intraoral Camera is a feasible and potentially cost-effective alternative to a visual oral examination for caries screening, especially early childhood caries, in preschool children attending childcare centers.

Teledentistry in inner-city child-care centres.
Journal of telemedicine and telecare, 2006Co-Authors: Dorota T. Kopycka-kedzierawski, Ronald J. BillingsAbstract:In Rochester, NY, telehealth centres were established in six inner-city elementary schools and seven child-care centres. The teledentistry project complemented the existing telehealth model. Using an Intraoral Camera, telehealth assistants record digital images of children's teeth (768 x 494 pixels) and send the images to a computer at the expert dental site (the Eastman Department of Dentistry at the University of Rochester). The paediatric dentist at the expert site reviews the images, and provides referral and treatment recommendations. Subsequently, the telehealth assistant contacts the child's parents or guardians and assists them to obtain appropriate dental care for their child. In the pilot study, we screened 50 children. In the first nine months of 2005, we screened 123 children. The results of our initial teledental screenings of children aged 12-48 months attending inner-city child-care centres revealed that almost 40% had active dental caries, mainly early childhood caries (ECC). For the first time, many children attending inner-city child-care centres have had their teeth examined at an early age and been given prompt feedback on the need for dental care.
