<section style="margin:0 0 32px 0;"><article style="margin:0 0 28px 0;">
<h3 style="font-size:23px;margin:0 0 14px 0;color:#171411;">What does "persistence, ulceration and unexplained change" mean for me as a patient?</h3>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">One of the most common questions patients ask about this topic concerns persistence, ulceration and unexplained change. The answer is not as simple as one might hope โ but research now provides clear guidance.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The systematic review by Mazur et al. (2021) analyzed 43 studies on imaging-based in-vivo techniques for early diagnosis of oral potentially malignant disorders. They examined autofluorescence (VELscope), chemiluminescence (ViziLite, MicroLux), optical coherence tomography and other imaging methods. The analysis of multiple studies from 34 included studies reached a clear conclusion: none of the techniques examined can replace tissue sampling (biopsy) as the definitive test. While autofluorescence showed acceptable sensitivity for detecting dysplastic changes, its usefulness was limited by false-positive findings in inflammatory conditions.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Shrivastava et al. (2022) added to these findings with a review of studies on vibrational spectroscopy methods (Raman spectroscopy and FTIR). The combined sensitivity reached 99% and specificity 94% with an AUC of 0.99. The subgroup analysis showed comparable high values for each method individually: Raman spectroscopy (sensitivity 1.00; specificity 0.93) and FTIR (sensitivity 0.98; specificity 0.96). However, the variation between studies was substantial (Iยฒ for sensitivity: 93.4%; for specificity: 94.5%), which limits how widely these results can be applied.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Li et al. (2024) examined in a systematic review the diagnostic accuracy of artificial intelligence (AI) combined with clinical imaging. The overall diagnostic odds ratio was 68.4, with an AUC of 0.938. The AI-assisted analysis achieved a sensitivity of 89.9%, a specificity of 89.2% and a negative predictive value of 89.5%. The meta-regression analysis found no significant difference between different imaging tools, with the subgroup analysis identifying clinical photography as the most accurate method.</p>
``````html
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In summary, optical and imaging methods show significant potential as a screening supplement, especially in low-resource settings. The combination of AI and smartphone photography could bring the diagnostic level of general dentists closer to that of specialists (Li et al. 2024). However, biopsy remains the gold standard for definitive diagnosis. A major unresolved problem with all imaging methods is distinguishing between inflammatory and dysplastic changes, which have overlapping clinical features.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Methodologically, it's important to note that the included studies vary significantly in study design, follow-up period, and population selection. This variation limits the comparability of results and explains why pooled effect estimates must be interpreted with caution. However, the direction of the effect is consistent across different study types.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For applying these findings to German-speaking healthcare systems, it's also relevant that a large portion of the scientific evidence comes from English-speaking or Scandinavian healthcare systems. Differences in payment structures, treatment practices, and patient access can influence effect sizes without invalidating the basic findings.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For your dental practice, these findings mean that additional imaging can usefully supplement clinical examination but cannot replace professional judgment and biopsy decisions. Autofluorescence and similar methods can particularly help identify suspicious areas in large lesions, allowing more targeted biopsy site selection.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The most promising scenario for the near future is AI-supported analysis of clinical photographs: This method requires no special equipment and could become widely available through smartphone apps. However, prospective validation studies in real practice settings are still lacking, and regulatory hurdles have not yet been overcome.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In everyday practice, this means: Scientific evidence doesn't provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as overall health, compliance, individual risk profiles, and treatment preferences must be included in the decision.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What does this mean for you? The information should convey understanding rather than panic.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">As a patient, it's important to know: No examination method is perfect. Research shows which conditions make a method most reliable and when you should ask for a second opinion.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Science has studied this topic intensively in recent years. For this article, more than 11 scientific studies were reviewed. It's important to understand: Not every study carries equal weight. Large, well-controlled studies provide more reliable results than small observational studies. Looking at all these different studies together gives us the picture we're presenting to you here.</p>

<h3 style="font-size:23px;margin:0 0 14px 0;color:#171411;">What does "patient risk profile" mean for me as a patient?</h3>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">When it comes to patient risk profile, the research is clearer than many people think. Here you'll learn what current studies actually show.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Hernรกndez-Mancera et al. (2024) conducted an exploratory systematic review of saliva-based biomarkers for detecting oral squamous cell carcinoma (OSCC). The analysis included 62 studies with 5,278 patients (2,546 with OSCC, 1,070 with oral potentially malignant disorder, 1,662 controls). Over 60 different saliva molecules were examined, with six markers in four or more studies consistently showing high sensitivity and specificity values: IL-8, IL-1ฮฒ, IL-6, TNF-ฮฑ, LDH, and MMP-9. In particular, IL-8, examined in seven studies, reliably distinguished between OSCC patients and healthy controls, although the evidence for differentiating between oral potentially malignant disorder and healthy controls was less consistent.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The systematic review of saliva-based microRNAs by Oancea et al. (2025) evaluated 33 studies and identified numerous dysregulated microRNAs. Among upregulated microRNAs, miR-21, miR-31, miR-184, miR-146a, and miR-155 were the most frequently reported. miR-21 was described in five studies as significantly elevated in oral potentially malignant disorder samples compared to healthy controls, with a gradual increase from healthy tissue to oral potentially malignant disorder without dysplasia, to oral potentially malignant disorder with dysplasia, and OSCC. The sensitivity and specificity of individual microRNAs varied considerably: miR-181b achieved 94.1% sensitivity and 81.2% specificity, while miR-21 showed only 60โ66% sensitivity at 69โ90% specificity.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Nazar et al. (2024) examined in a systematic review with meta-analysis the diagnostic value of saliva metabolomics in oral potentially malignant disorder and oral cancer. Nine studies were included, which described heterogeneous metabolite profiles. Meta-analysis could only be performed for N-acetylglucosamine and showed no significant difference between oral potentially malignant disorder/cancer patients and controls (standardized mean difference = 0.15; 95% confidence interval: โ0.25 to 0.56). Although individual studies reported significant changes in metabolites such as glycine, proline, and ornithine, the data were insufficient for pooled assessment.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Despite the abundance of biomarkers studied, no established single saliva biomarker or validated biomarker panel for clinical use exists today. All reviews consistently emphasize that most promising markers have been examined in only individual studies with small groups. Particularly critical is that confounding factors such as gum disease (periodontitis), tobacco use, and alcohol can influence saliva concentrations of several markers and were not adequately controlled in many studies.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Methodologically, it's important to note that the included studies vary significantly in study design, follow-up period, and population selection. This variation limits the comparability of results and explains why pooled effect estimates must be interpreted with caution. However, the direction of the effect is consistent across different study types.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For applying these findings to German-speaking healthcare systems, it's also relevant that a large portion of the scientific evidence comes from English-speaking or Scandinavian healthcare systems. Differences in payment structures, treatment practices, and patient access can influence effect sizes without invalidating the basic findings.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For dental practice, saliva-based biomarkers are currently not yet usable as independent diagnostic tools. Their greatest potential lies in combining multiple markers into diagnostic panels that could enable opportunistic screening in high-risk patients โ particularly in settings with limited access to histopathological diagnostics.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Research into saliva-based microRNAs opens up the prospect of predictive diagnostics in the future: certain microRNA patterns (particularly miR-21 overexpression with increasing dysplasia) could eventually help identify oral potentially malignant disorder with high transformation risk early on, before clinical signs of progression become visible.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In everyday practice, this means: Scientific evidence doesn't provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as overall health, compliance, individual risk profiles, and treatment preferences must be included in the decision.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What does this mean for you? Warning signs must be linked to patient context.</p>

<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">As a patient, it's important for you to know: No examination method is perfect. Research shows under which conditions a method is most reliable and when you should ask for a second opinion.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">How do scientists reach these conclusions? They don't just look at a single study, but examine many investigations at the same time. This helps them determine whether a result was a chance finding or whether it keeps repeating. In this case, the findings are based on 11 scientific papers from different countries and research groups.</p>

<article style="margin:0 0 28px 0;">
<h3 style="font-size:23px;margin:0 0 14px 0;color:#171411;">What does "monitor, biopsy, refer" mean for me as a patient?</h3>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">One point that often causes uncertainty is "monitor, biopsy, refer." However, science has made important progress in recent years.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Epidemiological data consistently shows that the malignant transformation rate of oral potentially malignant disorders (OPMD) is variable but clinically relevant. For leukoplakia, an annual malignant transformation rate of approximately 1โ3% is reported, and for erythroplakia 2.7% per year (Oancea et al. 2025). Oral submucous fibrosis has the highest risk among common OPMD with a transformation rate of 5.2% (Nazar et al. 2024). The WHO prevalence rate of OPMD worldwide is 1โ5%, with the highest incidence in South Asia, which is associated with widespread consumption of betel, areca nut, and tobacco (Mazur et al. 2021; Shi et al. 2024).</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Classic risk factors โ tobacco use, alcohol abuse, and HPV infection โ are well-established in scientific evidence and lower the clinical threshold for diagnostic escalation. Oancea et al. (2025) emphasize that smoking, alcohol, and HPV infection are strongly associated with oral carcinogenesis and disrupt local balance through DNA mutation and genetic alteration. Studies of saliva biomarkers have reported that tobacco use and gum disease (periodontitis) can affect IL-8 and LDH concentrations in saliva (Hernรกndez-Mancera et al. 2024), which makes interpreting diagnostic tests in at-risk patients more difficult.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Histopathological evaluation with dysplasia grading remains the recognized standard for risk stratification. However, scientific evidence points to relevant observer variation: the classification of dysplasia grades is subjective and can differ significantly between pathologists. This is a core issue because the clinical decision โ monitor versus biopsy versus refer โ in dental practice often depends on morphological assessment.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Scientific evidence from the microRNA field suggests a possible molecular supplement to histopathological risk stratification. The gradual increase in saliva miR-21 from healthy tissue through non-dysplastic OPMD to dysplastic OPMD and oral squamous cell carcinoma (Oancea et al. 2025) supports a continuum model of oral carcinogenesis. Similarly, increasing dysregulation of miR-320a in oral lichen planus progression shows inverse correlation with VEGFR-2 expression, which is associated with angiogenic activation and tumor progression.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">Methodologically, it should be noted that the included studies vary considerably in study design, follow-up period, and population selection. This variability limits the comparability of results and explains why pooled effect estimates must be interpreted with caution. Nevertheless, the direction of the effect is consistent across different study types.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For application in German-speaking healthcare, it is also relevant that a significant portion of the scientific evidence comes from English-speaking or Scandinavian healthcare systems. Differences in payment structures, treatment culture, and patient access can affect effect sizes without making the basic statement invalid.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">For dental practice, clear action thresholds can be derived from the scientific evidence: Any persistent (> 2โ3 weeks) tissue change without an obvious cause requires systematic assessment. Warning signs that require immediate evaluation include induration, fixed ulceration, changes that don't respond to treatment, and changes in patients with a known risk profile.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">The escalation logic follows a three-step model: (1) Follow-up visit after 2โ3 weeks for presumably reactive changes, (2) Biopsy for persistent or clinically suspicious findings, (3) Referral to a specialized center for histologically confirmed dysplasia or suspected malignancy. Importantly, the patient's risk profile lowers the threshold for escalation.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">In daily practice, this means: Scientific evidence doesn't provide a one-size-fits-all answer, but rather a framework for individualized decisions. Patient-specific factors such as general health, compliance, individual risk profiles, and treatment preferences must be part of the decision.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What does this mean for you? Clear action thresholds are essential for guidance.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">As a patient, it's important for you to know: No examination method is perfect. Research shows under which conditions a method is most reliable and when you should ask for a second opinion.</p>
<p style="margin:0 0 14px 0;color:#3b362f;line-height:1.82;">What makes these results reliable? In medical research, the rule is: the more independent studies that reach the same conclusion, the more certain the statement. The type of study and the number of participants also play an important role. Large controlled studies with many participants provide more reliable results than small surveys.</p>
