Background/objectives: The diagnosis of oral potentially malignant disorders (OPMDs) and oral squamous cell carcinoma (OSCC) represent a significant challenge in oral medicine. Optical coherence tomography (OCT) shows promise for evaluating oral tissue microstructure but lacks standardized diagnostic protocols tailored to the structural variability and lesions of oral mucosa.
Methods: This cross-sectional observational study aims to evaluate the diagnostic accuracy of targeted biopsy-based and site-coded OCT protocols for common OPMDs and OSCC.

Article Synopsis
- The study compared tissue artifacts occurring in punch and scalpel biopsies of oral and maxillofacial lesions using systematic review and meta-analysis methodologies.
- Four studies focusing on various artifacts were included, showing scalpel biopsies were significantly more likely to exhibit issues like crushes, splits, and fragmentation compared to punch biopsies.
- The findings concluded that punch biopsies generally resulted in fewer artifacts, suggesting they may be the preferable option for obtaining tissue samples in this context.

June 2015
Centre for Evidence-based Dentistry, Dental Health Services Research Unit, University of Dundee, Dundee, Scotland, UK.
Article Synopsis
- The study analyzed various diagnostic tests (like vital staining and oral cytology) to detect potentially malignant disorders (PMD) or oral cancer using data from multiple medical databases.
- Independent reviewers assessed the quality of relevant studies and extracted data, focusing on tests used alongside traditional examinations, with scalpel biopsy as the reference standard.
- The findings indicated that none of the adjunctive tests were reliable enough to replace scalpel biopsy, although oral cytology showed promise due to higher sensitivity and specificity estimates.
Clinical correlative study on early detection of oral cancer and precancerous lesions by modified oral brush biopsy and cytology followed by histopathology.

Article Synopsis
- Direct immunofluorescence (DIF) is a key method for diagnosing bullous diseases and autoimmune conditions, but its detection rate can be influenced by factors like the biopsy site, the number of biopsies, and the instruments used.
- A study at the Universidad de Buenos Aires reviewed 136 cases and found that DIF detection rates varied among conditions, with the highest rate in pemphigus vulgaris (100%) and a lower rate in bullous pemphigoid (55.6%).
- It was discovered that increasing the number of biopsies improved detection rates, and biopsies taken with a punch had a significantly higher detection rate compared to scalpel biopsies (71.7% vs. 39.1%).
Biopsy of the buccal mucosa in oral lichen planus: the traditional method versus the use of a new pressure forceps.

Department of Oral Medicine, University of Murcia, Spain.
Article Synopsis
- The authors developed a new tool called "B forceps" for biopsies and compared its effectiveness with traditional methods using specimens from patients diagnosed with oral lichen planus.
- In a study with 84 patients, group A used conventional biopsy techniques, while group B utilized the B forceps; results showed that group B had significantly fewer issues like fragmentation and hemorrhages.
- The B forceps not only improved visibility during the procedure but also reduced surgical time and produced higher-quality biopsy specimens with fewer artifacts.
[Incisional biopsy in oral medicine: punch vs traditional procedure].

Article Synopsis
- The study compares artefacts from incisional biopsies using punch versus scalpel techniques, focusing on how suture use affects specimen handling.
- A total of 160 samples from pig tongues were evaluated by oral surgeons for handling artefacts like crush, splits, fragmentation, and pseudocysts.
- Findings revealed that while artefacts like crush and fragmentation were similar between methods, stitches increased splits and overall artefacts in scalpel biopsies, suggesting suture usage should be limited to specimen orientation only.
