Methods A total of 185 anterior composite restorations were evaluated by calibrated restorative dentistry specialists. Restorations were scored according to the FDI criteria as intact, requiring repair, or needing replacement. Clinical examination was considered the gold standard. Photographs were taken under standardized conditions, and inter-observer and inter-method agreement were analyzed using Cohen’s Kappa and intraclass correlation coefficient (ICC). Results High inter-observer agreement was observed across all methods (Kappa = 0.928–1.0). Good to excellent agreement was found between clinical examination and digital photography methods for FDI final scores (Kappa = 0.775–0.973, p < 0.001). Photographs taken with the lens-equipped smartphone and macro camera showed higher agreement with clinical examination (Kappa = 0.973). Conclusion Digital photography, particularly with a lens-equipped smartphone and macro camera, offers effectiveness comparable to clinical examination in evaluating anterior composite restorations. anterior composite restorations digital photography FDI criteria lens-equipped smartphone teledentistry Figures Figure 1 Clinical Relevance This study demonstrates that intraoral digital photography, particularly with a lens-equipped smartphone and macro camera, achieves diagnostic outcomes closely aligned with clinical examination using FDI criteria. While smartphones alone are practical, lens-assisted imaging enhances accuracy, supporting its use as a cost-effective alternative to professional macro cameras. Introduction The clinical success of dental restorations is a significant area of research concerning diagnosis, treatment, and restoration longevity [ 1 ]. The growing interest in evidence-based dentistry has increased the number of clinical studies on this topic [ 2 ]. Composite resins, like other restorative materials, have a limited lifespan [ 3 ]. It is estimated that 56% of restorations applied to treated teeth are used to replace existing restorations rather than to treat primary caries [ 4 ]. Among the reasons for the failure of intraoral composite restorations, secondary caries is the most common cause [ 5 ]. Following secondary caries, frequent reasons for replacing composite restorations include marginal fracture (18%), marginal discoloration (9%), complete fracture (7%), tooth fracture (7%), complete discoloration (6%), and pain (1%) [ 6 ]. In cases where there are no secondary caries beneath the restoration but deterioration is present at the margins, repair of the restoration may be preferred [ 7 ]. When making this decision, clinicians may rely on their clinical experience, leading to subjective judgments. For the evaluation of restorations, the World Dental Federation (FDI) criteria and the modified United States Public Health Service (USPHS)/Ryge criteria are widely used [ 8 , 9 ]. However, despite being well-defined, these criteria are often considered complex for routine clinical use and can lead to subjective evaluations, even among experienced clinicians [ 4 , 10 ]. The FDI criteria, which include functional, biological, and aesthetic categories with several subcategories. The final score was based on the worst subcategory score: intact (1–3), requiring repair (4, partial failure), or replacement (5, complete failure). The distinction between scores 4 and 5 depends on whether the defect can be repaired or necessitates full replacement [ 9 ]." Digital photography has emerged as an alternative that reduces bias in evaluating restoration quality. One of its primary uses is to allow clinicians to photograph restorations and send them to impartial researchers for assessment. Intraoral photography is recognized as a reliable diagnostic method for evaluating dental caries, trauma, and restorations [ 11 ]. Modern technology has found its place in the medical world, as in every aspect of our lives. These advancements have created a new field called teledentistry, where telecommunications and dentistry are used together [ 12 ]. Dental photography requires specific technical precision due to the challenging conditions of the intraoral environment. Today, to achieve ideal image quality, interchangeable-lens cameras equipped with macro lenses offering 1:1 magnification are used in combination with light sources such as macro ring flashes. However, these systems are both costly and bulky, presenting disadvantages [ 13 ]. In contrast, the widespread use of smartphones offers a low-cost and practical photography solution, although image quality may vary between devices [ 14 ]. Smartphone megapixels are not equivalent to those of Digital Single-Lens Reflex (DSLR) cameras because smartphones have smaller camera sensors [ 15 ]. However, the cost of a smartphone with a detachable telephoto lens setup is approximately half that of a DSLR. A telephoto lens enables zooming without reducing image resolution and increases focal length instead of cropping and enlarging the image. All iPhone models starting from the iPhone 11 Pro are equipped with a telephoto lens [ 16 ]. This study is the first to investigate the validity of intraoral digital photography in evaluating anterior composite restorations. Our hypothesis is that photographs taken with a smartphone, a lens-equipped smartphone, and a macro-lens camera will yield results comparable to clinical examination. Materials and Methods Study Design This study is a validation study examining the use of intraoral digital photography in evaluating anterior composite restorations. The study was deemed scientifically and ethically appropriate by the Non-Interventional Clinical Research Ethics Committee of XXX University Faculty of Medicine under decision number XXX. Participants signed an informed consent form explaining the study’s purpose, content, and methods. Participants and Sample The study included 185 anterior teeth with composite restorations from individuals aged 18–64 who applied to the Department of Restorative Dentistry at XXX University. Primary teeth, unrestored teeth, and teeth with amalgam, glass ionomer, or indirect restorations were excluded. Evaluation Methods Restorations were classified according to FDI criteria as intact (scores 1–3), requiring repair (score 4), or needing replacement (score 5) [ 5 ]. Clinical examination was considered the gold standard. Photographs were taken using an iPhone 14 Pro (48 MP main camera, 12 MP ultra-wide camera), an iPhone 14 Pro with a 2IN1 Phone Macro Lens, a Canon Rebel XTi (CMOS sensor, 3888x2592 pixels), and a Canon EF 100mm f/2.8 Macro IS USM lens. Photographs were captured under standardized lighting (28 Watt matte white LED) at a distance of 10 cm (smartphone) or 20 cm (macro camera), using lip-cheek retractors and positioning the camera perpendicular to the tooth surface. For the iPhone 14 Pro, focusing was done by tapping the screen; for macro lens photography, a ring flash was used. Macro photography settings included an aperture of f/22, ISO 200, exposure time of 1/160 second, and a Macro Ring Lite MR-14EX II flash. All images were saved in JPEG format (Fig. 1). Calibration and Evaluation Evaluations were conducted by two restorative dentistry specialists. Calibration was performed on 20 anterior teeth with restorations, which were not included in the study, using both clinical and digital methods. For clinical examination, a mirror, a rounded-tip probe, and a reflector light were used, and bite-wing and panoramic radiographs were reviewed. Photographs were taken by an experienced clinician. The captured photographs were scored by two different restorative dentistry specialists according to FDI criteria. Based on the FDI criteria, restorations were scored as follows: no intervention required (scores 1, 2, 3) with a final score of 1, repair required (score 4) with a final score of 2, and replacement required (score 5) with a final score of 3. Statistical Analysis The sample size was calculated using G*Power 3.1.9.2 with a 95% confidence interval, α = 0.05, and a theoretical power of 0.80, determining a minimum of 175 restorations [70]. Inter-observer and inter-method agreement were assessed using Cohen’s Kappa statistic and the Intraclass Correlation Coefficient (ICC). Kappa was used for categorical variables, and ICC for quantitative variables, with a significance level of p < 0.05. Analyses were performed using IBM SPSS V23. Results Interobserver Agreement The interobserver agreement for FDI final scores was found to be high across all imaging methods (Kappa = 0.928–1.0, p < 0.001). Interobserver agreement was evaluated for each criterion according to the imaging methods (Table 1 ). Within the smartphone method, a statistically significant good level of agreement was observed between the observers for the criteria of material fracture, proximal contact point, surface gloss and texture, marginal discoloration, and color match. A statistically significant moderate level of agreement was found for marginal adaptation and anatomical form and contour. In both the smartphone with lens method and the macro photography method, a statistically significant good level of agreement was obtained between the observers for all evaluated criteria.

The methods were compared with clinical examination using Observer 2 as the reference. Agreement between the methods was evaluated based on the final FDI scores. A good level of agreement was found between clinical examination and smartphone photography (Kappa = 0.775, p < 0.001), while very good agreement was observed with the smartphone plus lens and macro photography methods (Kappa = 0.973, p < 0.001) (Table 2 ).

A good level of agreement was found between clinical examination and the smartphone method for material fracture; moderate agreement was observed for marginal adaptation, proximal contact point, form and contour, caries at the restoration margin, surface gloss, surface texture, marginal staining, and color match; and low agreement was detected for hard tissue defects at the restoration margin. Between clinical examination and both the smartphone with lens and macro photography methods, good agreement was found for material fracture, caries at the restoration margin, and marginal staining; moderate agreement was observed for other criteria; and low agreement was found for hard tissue defects.

A binary scoring system was used to calculate the overall failure rate: 0 = no failure, 1 = failure (repair or replacement). For failure detection, the smartphone method demonstrated 93.57% sensitivity, 91.11% specificity, 97.04% positive predictive value (PPV), and 82% negative predictive value (NPV). Both the smartphone with lens and macro photography methods exhibited excellent diagnostic performance with 100% sensitivity, specificity, PPV, and NPV.

No similar study in the literature has evaluated restoration quality in the context of teledentistry using a smartphone (iPhone 14 Pro), a lens-equipped smartphone (2IN1 Phone Macro Lens), and a macro-lens digital camera (Canon Rebel XTi). Thus, this study provides an original contribution by comparing the effectiveness of these three methods. The results indicate high inter-observer agreement across all methods (Kappa = 0.928–1.0). The smartphone method showed slightly lower agreement compared to the lens-equipped smartphone and macro camera, likely due to the smartphone camera’s lower resolution and detail-capturing capacity [ 9 ]. Kohara et al. [ 9 ] used a smartphone and macro camera for occlusal caries detection, reporting Kappa values ranging from 0.60–0.66. In contrast, this study achieved higher Kappa values (0.775–0.973), which may be attributed to the technological superiority of the devices used (e.g., the iPhone 14 Pro’s 48 MP camera) and standardized imaging conditions. Signori et al. [ 11 ] reported low to moderate agreement (Kappa = 0.12–0.34) for anterior restorations evaluated with an intraoral camera. However, this study found good to excellent agreement for anterior restorations (Kappa = 0.775–0.973). This difference may stem from the superior resolution of the images used in this study (2268x4032–5472x3648 pixels) compared to the intraoral camera’s resolution (1024x768 pixels). Additionally, the accessibility of the anterior region likely enhanced image quality and diagnostic accuracy. Lower agreement was observed between methods for marginal adaptation, proximal contact points, and form/contour criteria. This may be due to the two-dimensional nature of digital photography, which lacks the perceptual capacity provided by tactile examination [ 17 , 18 ]. Valizadeh-Haghi et al. [ 18 ] reported that smartphone photographs were inadequate for detecting marginal adaptation. Clinical examination with a probe allows for more precise evaluation of marginal adaptation [ 17 ]. This suggests that digital methods may be limited in criteria requiring detailed assessment. Aesthetic criteria, particularly color match, were identified as a leading cause of restoration failure [ 19 ]. However, the evaluation of these criteria can vary based on clinicians’ experience and subjective perceptions. Simplifying the FDI criteria into three final scores (intact, repair, replacement) in this study may have increased inter-observer and inter-method agreement. This finding supports the idea that less complex scoring systems can provide more consistent results in clinical evaluations [ 20 ]. The smartphone method was effective in detecting obvious failures, such as material fractures, but limited in detailed assessments like marginal adaptation and proximal contact points. In contrast, the lens-equipped smartphone and macro camera provided results closely comparable to clinical examination, emerging as strong alternatives for teledentistry applications [ 16 , 21 ]. Notably, the lens-equipped smartphone, offering high-resolution images, may serve as a cost-effective alternative to the macro camera. A study in plastic surgery reported that a lens-equipped smartphone (iPhone 11 + Moment 58 mm telephoto lens) performed similarly to a macro-lens DSLR camera [ 16 ]. Similarly, this study observed that the lens-equipped smartphone yielded FDI scores nearly equivalent to those of the macro camera. The study’s limitations include the inadequacy of digital photography in criteria requiring tactile examination (e.g., marginal adaptation, hard tissue defects). Additionally, the subjective nature of aesthetic criteria may lead to inter-evaluator differences. To address this, comprehensive calibration of evaluators based on FDI criteria is recommended [ 20 ]. Finally, the study only covered anterior restorations, and the effectiveness of these methods for posterior restorations requires further investigation. Conclusion This study confirms that intraoral digital photography, particularly with a lens-equipped smartphone and macro-lens camera, offers effectiveness comparable to clinical examination in evaluating anterior composite restorations. While the iPhone 14 Pro stands out for its practicality and accessibility, its image quality is slightly inferior to that of the lens-equipped smartphone and macro camera. The lens-equipped smartphone holds high potential as a cost-effective alternative to the macro camera in teledentistry applications. Digital photography contributes to clinical practice as a rapid, effective, and cost-saving method for evaluating restorations based on FDI criteria. Technological advancements, particularly improvements in smartphone camera systems, suggest that this method will become more widespread and reliable in the future. Future studies focusing on posterior restorations and comparisons of different devices can further expand these findings.

The growing interest in evidence-based dentistry has increased the number of clinical studies on this topic [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eComposite resins, like other restorative materials, have a limited lifespan [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. It is estimated that 56% of restorations applied to treated teeth are used to replace existing restorations rather than to treat primary caries [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. Among the reasons for the failure of intraoral composite restorations, secondary caries is the most common cause [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. Following secondary caries, frequent reasons for replacing composite restorations include marginal fracture (18%), marginal discoloration (9%), complete fracture (7%), tooth fracture (7%), complete discoloration (6%), and pain (1%) [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eIn cases where there are no secondary caries beneath the restoration but deterioration is present at the margins, repair of the restoration may be preferred [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. When making this decision, clinicians may rely on their clinical experience, leading to subjective judgments.\u003c/p\u003e \u003cp\u003eFor the evaluation of restorations, the World Dental Federation (FDI) criteria and the modified United States Public Health Service (USPHS)/Ryge criteria are widely used [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e, \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. However, despite being well-defined, these criteria are often considered complex for routine clinical use and can lead to subjective evaluations, even among experienced clinicians [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e, \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe FDI criteria, which include functional, biological, and aesthetic categories with several subcategories. The final score was based on the worst subcategory score: intact (1\u0026ndash;3), requiring repair (4, partial failure), or replacement (5, complete failure). The distinction between scores 4 and 5 depends on whether the defect can be repaired or necessitates full replacement [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e].\"\u003c/p\u003e \u003cp\u003eDigital photography has emerged as an alternative that reduces bias in evaluating restoration quality. One of its primary uses is to allow clinicians to photograph restorations and send them to impartial researchers for assessment. Intraoral photography is recognized as a reliable diagnostic method for evaluating dental caries, trauma, and restorations [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eModern technology has found its place in the medical world, as in every aspect of our lives. These advancements have created a new field called teledentistry, where telecommunications and dentistry are used together [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. Dental photography requires specific technical precision due to the challenging conditions of the intraoral environment. Today, to achieve ideal image quality, interchangeable-lens cameras equipped with macro lenses offering 1:1 magnification are used in combination with light sources such as macro ring flashes. However, these systems are both costly and bulky, presenting disadvantages [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eIn contrast, the widespread use of smartphones offers a low-cost and practical photography solution, although image quality may vary between devices [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e]. Smartphone megapixels are not equivalent to those of Digital Single-Lens Reflex (DSLR) cameras because smartphones have smaller camera sensors [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. However, the cost of a smartphone with a detachable telephoto lens setup is approximately half that of a DSLR. A telephoto lens enables zooming without reducing image resolution and increases focal length instead of cropping and enlarging the image. All iPhone models starting from the iPhone 11 Pro are equipped with a telephoto lens [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThis study is the first to investigate the validity of intraoral digital photography in evaluating anterior composite restorations.

For the iPhone 14 Pro, focusing was done by tapping the screen; for macro lens photography, a ring flash was used. Macro photography settings included an aperture of f/22, ISO 200, exposure time of 1/160 second, and a Macro Ring Lite MR-14EX II flash. All images were saved in JPEG format (Fig.\u0026nbsp;1).\u003c/p\u003e\n\u003ch3\u003eCalibration and Evaluation\u003c/h3\u003e\n\u003cp\u003eEvaluations were conducted by two restorative dentistry specialists.

assessing anterior composite restorations, compared to clinical examination, using FDI criteria. No similar study in the literature has evaluated restoration quality in the context of teledentistry using a smartphone (iPhone 14 Pro), a lens-equipped smartphone (2IN1 Phone Macro Lens), and a macro-lens digital camera (Canon Rebel XTi). Thus, this study provides an original contribution by comparing the effectiveness of these three methods.\u003c/p\u003e \u003cp\u003eThe results indicate high inter-observer agreement across all methods (Kappa\u0026thinsp;=\u0026thinsp;0.928\u0026ndash;1.0). The smartphone method showed slightly lower agreement compared to the lens-equipped smartphone and macro camera, likely due to the smartphone camera\u0026rsquo;s lower resolution and detail-capturing capacity [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. Kohara et al. [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e] used a smartphone and macro camera for occlusal caries detection, reporting Kappa values ranging from 0.60\u0026ndash;0.66. In contrast, this study achieved higher Kappa values (0.775\u0026ndash;0.973), which may be attributed to the technological superiority of the devices used (e.g., the iPhone 14 Pro\u0026rsquo;s 48 MP camera) and standardized imaging conditions.\u003c/p\u003e \u003cp\u003eSignori et al. [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e] reported low to moderate agreement (Kappa\u0026thinsp;=\u0026thinsp;0.12\u0026ndash;0.34) for anterior restorations evaluated with an intraoral camera. However, this study found good to excellent agreement for anterior restorations (Kappa\u0026thinsp;=\u0026thinsp;0.775\u0026ndash;0.973). This difference may stem from the superior resolution of the images used in this study (2268x4032\u0026ndash;5472x3648 pixels) compared to the intraoral camera\u0026rsquo;s resolution (1024x768 pixels). Additionally, the accessibility of the anterior region likely enhanced image quality and diagnostic accuracy.\u003c/p\u003e \u003cp\u003eLower agreement was observed between methods for marginal adaptation, proximal contact points, and form/contour criteria. This may be due to the two-dimensional nature of digital photography, which lacks the perceptual capacity provided by tactile examination [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e, \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e]. Valizadeh-Haghi et al. [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e] reported that smartphone photographs were inadequate for detecting marginal adaptation. Clinical examination with a probe allows for more precise evaluation of marginal adaptation [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]. This suggests that digital methods may be limited in criteria requiring detailed assessment.\u003c/p\u003e \u003cp\u003eAesthetic criteria, particularly color match, were identified as a leading cause of restoration failure [\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e]. However, the evaluation of these criteria can vary based on clinicians\u0026rsquo; experience and subjective perceptions. Simplifying the FDI criteria into three final scores (intact, repair, replacement) in this study may have increased inter-observer and inter-method agreement. This finding supports the idea that less complex scoring systems can provide more consistent results in clinical evaluations [\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe smartphone method was effective in detecting obvious failures, such as material fractures, but limited in detailed assessments like marginal adaptation and proximal contact points. In contrast, the lens-equipped smartphone and macro camera provided results closely comparable to clinical examination, emerging as strong alternatives for teledentistry applications [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e]. Notably, the lens-equipped smartphone, offering high-resolution images, may serve as a cost-effective alternative to the macro camera. A study in plastic surgery reported that a lens-equipped smartphone (iPhone 11\u0026thinsp;+\u0026thinsp;Moment 58 mm telephoto lens) performed similarly to a macro-lens DSLR camera [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e]. Similarly, this study observed that the lens-equipped smartphone yielded FDI scores nearly equivalent to those of the macro camera.\u003c/p\u003e \u003cp\u003eThe study\u0026rsquo;s limitations include the inadequacy of digital photography in criteria requiring tactile examination (e.g., marginal adaptation, hard tissue defects). Additionally, the subjective nature of aesthetic criteria may lead to inter-evaluator differences. To address this, comprehensive calibration of evaluators based on FDI criteria is recommended [\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e]. Finally, the study only covered anterior restorations, and the effectiveness of these methods for posterior restorations requires further investigation.\u003c/p\u003e"},{"header":"Conclusion","content":"\u003cp\u003eThis study confirms that intraoral digital photography, particularly with a lens-equipped smartphone and macro-lens camera, offers effectiveness comparable to clinical examination in evaluating anterior composite restorations. While the iPhone 14 Pro stands out for its practicality and accessibility, its image quality is slightly inferior to that of the lens-equipped smartphone and macro camera. The lens-equipped smartphone holds high potential as a cost-effective alternative to the macro camera in teledentistry applications.\u003c/p\u003e \u003cp\u003eDigital photography contributes to clinical practice as a rapid, effective, and cost-saving method for evaluating restorations based on FDI criteria. Technological advancements, particularly improvements in smartphone camera systems, suggest that this method will become more widespread and reliable in the future.
