“…Other authors [ 14 15 22 23 24 25 27 ] used the width of the cervical lesion on digital photographs as a parameter to estimate the position of the CEJ, citing the method developed by Zucchelli et al [ 28 ]. A 2-dimensional image was used to determine the volume of coverage achieved in the cervical region affected by the NCCL without considering the morphological variations in the root surface resulting from NCCLs with different shapes [ 47 ].…”

Purpose This systematic review aimed to compare the efficacy, defined in terms of the mean percentage of root coverage (mRC), of surgical treatment approaches combined with adhesive restorations of non-carious cervical lesions (NCCLs) to that of root coverage alone in patients with a single gingival recession (GR) and NCCL. Methods A literature search was conducted to identify longitudinal studies reporting the mRC following treatment for the correction of GR defects associated with NCCLs using a combination of surgical and restorative techniques in systemically and periodontally healthy patients. Results The search resulted in the retrieval of 12,409 records. Seven publications met the inclusion criteria for the qualitative synthesis of data. The mRCs ranged from 69% to 97%. In the medium term, the gingival margin position was more stable when a connective tissue graft (CTG) was used, independently of whether restoration of teeth with NCCLs was performed. Conclusions The strength of the evidence was limited by methodological heterogeneity in terms of study design as well as the unit and period of analysis, which precluded a meta-analysis. Although no definitive conclusion could be drawn due to the lack of sufficient evidence to estimate the effectiveness of the interventions, CTG-based procedures contributed to gingival margin stability regardless of the performance of restoration to treat NCCLs.

“…Root caries is defined as a non-cavitated or cavitated lesion below the cemento-enamel junction (CEJ) that does not include the adjacent enamel [ 73 ]. A swept-source optical coherence tomographic observation was attempted on extracted human teeth to examine the prevalence of the exposed root surface [ 74 ]. This non-invasive method revealed that the occurrence of exposed dentin with 36.5% of the examined teeth but a higher percentage of buccal and lingual surfaces than proximal surfaces.…”

Root caries is a growing problem for the worldwide aging population. Silver diamine fluoride (SDF) contains high concentrations of silver and fluoride ions, which prevents and arrests root caries, as well as dentin caries in the primary teeth of young children. Unlike other fluoride products that mainly reduce the formation of new carious lesions, 38% SDF is an effective agent that can efficiently arrest the carious process, remineralize the decayed dental tissues, and protect the tooth structure against the formation of new caries lesions. The use of SDF can result in more caries-resistant tooth structures. Despite these merits, its clinical disadvantages are the deep penetration of silver ions and sequential formation of silver compounds, which cause esthetic concern due to the discoloration and impaired efficacy of dentin bonding after using SDF. Thus, this narrative review, by addressing the primary experimental results and clinical applications of SDF on root caries, proposes management methods for root caries in conjunction with the application of SDF. We propose a two-visit treatment protocol to take advantage of the SDF application for root surface caries and utilize the discoloration caused by SDF.

“…Optical coherence tomography (OCT) uses the basic principle of a weak coherence interferometer to carry out high-resolution cross-sectional tomography of the internal microstructure of materials or biological systems [ 13 ]. It has been widely used in many fields and has great scientific research and application potential in biomedical, agricultural and industrial detection [ 14 , 15 , 16 , 17 , 18 ]. In recent years, OCT has become a major tool to diagnose AMD and monitor its progress [ 19 ].…”

Age-related macular degeneration (AMD) is a retinal disorder affecting the elderly, and society’s aging population means that the disease is becoming increasingly prevalent. The vision in patients with early AMD is usually unaffected or nearly normal but central vision may be weakened or even lost if timely treatment is not performed. Therefore, early diagnosis is particularly important to prevent the further exacerbation of AMD. This paper proposed a novel automatic detection method of AMD from optical coherence tomography (OCT) images based on deep learning and a local outlier factor (LOF) algorithm. A ResNet-50 model with L2-constrained softmax loss was retrained to extract features from OCT images and the LOF algorithm was used as the classifier. The proposed method was trained on the UCSD dataset and tested on both the UCSD dataset and Duke dataset, with an accuracy of 99.87% and 97.56%, respectively. Even though the model was only trained on the UCSD dataset, it obtained good detection accuracy when tested on another dataset. Comparison with other methods also indicates the efficiency of the proposed method in detecting AMD.
