    Preoperative evaluation of depth of invasion can predict occult metastasis in cervical lymph nodes of OSCC patients and target patients who need neck dissection but there is no standard modality to determine this parameter preoperatively. The primary aim of this study was to evaluate the accuracy of a preoperative measurement of depth of invasion using Ultrasonography and correlate the values obtained with histologically determined DOI measurements. Specifically, we used a very small and thin Ultrasound probe, like a toothbrush, that help directly reach the oral lesions. We enrolled 32 biopsy proven primary T1/T2/T3 OSCC patients who underwent pre-operative intraoral ultrasound for the evaluation of the tumor diameter and depth of invasion. Ultrasound sensitivity, specificity and accuracy in the assessment of the infiltration of the lamina propria, the correlation between Ultrasound and histological depth of invasion and the correlation between diameter of the lesion and depth of invasion assessed with Ultrasound were evaluated. Ultrasound sensitivity and specificity in the assessment of the infiltration of the lamina propria were respectively 93.3% and 100%. A significant correlation was found between the measurement of US-obtained and histologically obtained depth of invasion (r = 0.907; p < .0001; 95% CI, 0.816 to 0.954). A medium correlation was found between diameter of the lesion and depth of invasion assessed with Ultrasound (r = 0.591; p < .0001; 95% CI, 0.306 to 0.779). According to our results, intraoral Ultrasound is very accurate in determining tumor depth of invasion in OSCC patients and represents a useful, cost-effective and promisig tool to insert in the diagnostic flow-chart of OSCC

    Can computer-guided surgery help orthodontics in miniscrew insertion and corticotomies? A narrative review

    Orthodontics has considerably increased the use of technology combined with surgery as a tool to improve dental movements in terms of predictability, acceleration of movement, and fewer side effects. To achieve these goals miniscrews and corticotomy were introduced. The digital workflow permits an increase in the accuracy of surgical and orthodontic setups. The tool that transfers the information is the CAD/CAM (Computer-Aided Design/ Computer-Aided Manufacturing) template. The aim of this review is to illustrate the use of computer-guided surgery in orthodontics regarding miniscrews and piezocision. The search strategy was a combination of Medical Subject Headings (Mesh) and free text words for PubMed. A total of 27 articles were included in this review: 16 concerned miniscrews and 11 concerned corticotomy. The current need for faster treatments, the improved systems of anchorage, and the evolution of imaging technologies require operators to be knowledgeable of the digital workflow. CAD/CAM templates allow greater precision and predictability of miniscrew insertion even if in the hands of less experienced clinicians and permit a better orientation and depth of the cortical incision. In conclusion, digital planning makes surgery faster and easier and allows for the identification and correction of any potential problem before the procedure

    The use of laser CO2 in salivary gland diseases

    Salivary gland diseases can include reactive lesions, obstructive lesions, and benign tumors. All these clinical entities are slow growing. Salivary glands reactive lesions, such as mucoceles, can result from extravasation of saliva into the surrounding soft tissue or from retention of saliva within the duct. Sialolithiasis, one of the most common obstructive lesions, is generally due to calculi, which are attributed to retention of saliva. Monomorphic adenoma is a salivary gland benign tumor, which is exclusively resulted from proliferation of epithelial cells, with no alterations interesting the connective tissue. The elective therapy of these lesions is surgical excision because sometimes they can be accompained by difficulties during chewing and phonation and can interfere with prosthesis's stability. The aim of the study is to evaluate the efficacy of CO2 laser in the treatment of patients with salivary gland diseases. Three different cases-a mucocele, a scialolithiasis and a monomorphic adenoma-were treated with CO2 laser excision (CW and 4W), under local anesthesia. Two different techniques were used: circumferential incision for the adenoma, and mucosa preservation technique for mucocele and sialolithiasis. In each case final haemostasis was obtained by thermocoagulation, but suture was applied to guarantee good healing by sewing up the flaps. The patients were checked after twenty days and the healing was good. The carbon dioxide laser (CO2 laser) was one of the earliest gas laser to be developed, and is still the highest-power continuous wave laser that is currently available. In dentistry the CO2 laser produces a beam of infrared light with the principal wavelength bands centering around 9.4 and 10.6 micrometers. Laser excision can be very useful in oral surgery. In the cases presented CO2 laser offered, differently from traditional surgery, simplified surgical technique, shorter duration of operation, minimal postoperative pain, minimal scarring, bloodless field and the possibility to realize minimally invasive surgery. These advantages made the operation tolerable for the patients, that became more compliant. Optimum functional results can be expected
