Naturally-Occurring Bioactives in Oral Cancer: Preclinical and Clinical Studies, Bottlenecks and Future Directions.

Oral cancer (OC) is the eighth most common cancer, particularly prevalent in developing countries. Current treatment includes a multidisciplinary approach, involving chemo, radio, and immunotherapy and surgery, which depends on cancer stage and location. As a result of the side effects of currently available drugs, there has been an increasing interest in the search for naturally-occurring bioactives for treating all types of cancer, including OC.

Natural Coumarins: Exploring the Pharmacological Complexity and Underlying Molecular Mechanisms.

Coumarins belong to the benzopyrone family commonly found in many medicinal plants. Natural coumarins demonstrated a wide spectrum of pharmacological activities, including anti-inflammatory, anticoagulant, anticancer, antibacterial, antimalarial, casein kinase-2 (CK2) inhibitory, antifungal, antiviral, Alzheimer's disease inhibition, neuroprotective, anticonvulsant, phytoalexins, ulcerogenic, and antihypertensive. There are very few studies on the bioavailability of coumarins; therefore, further investigations are necessitated to study the bioavailability of different coumarins which already showed good biological activities in previous studies.

Volumetric study of the maxillary sinus in patients with sinus pathology.

Objectives: The aim of this study is 1) to obtain the area and volumes of the maxillary sinuses in patients affected by clinically unilateral sinus pathology by comparing the results to the contralateral sinus and 2) to determine the importance of the volumetric measures when diagnosing the percentage of sinus obliteration.

Materials And Methods: A single-centre observational retrospective clinical study was conducted in 214 patients with clinically unilateral sinus pathologies. Linear (mm), area (mm2) and volume (mm3) measurements were taken from Cone Beam Computed Tomography (CBCT) images of the affected sinus as well as from the contralateral ones.

YouTube information about diabetes and oral healthcare.

Diabetes mellitus is a chronic disease that is increasing at an alarming rate all over the world. The aim of this study was to assess the quality information available on YouTube on diabetes and oral healthcare. This cross-sectional study made a search in YouTube (https://www.

Screening for prediabetes and risk of periodontal disease.

Objective: Diabetes and periodontitis are non-transmissible chronic disorders that exhibit a mutual relationship. A study was made to evaluate the risk of prediabetes and periodontal disease, and to explore the association between them.

Methods: A descriptive cross-sectional study was made of 186 individuals over 18 years of age, without prediabetes or diabetes, or cognitive impairment.

Plant-Derived Bioactives in Oral Mucosal Lesions: A Key Emphasis to Curcumin, Lycopene, Chamomile, , Green Tea and Coffee Properties.

Oral mucosal lesions have many etiologies, including viral or bacterial infections, local trauma or irritation, systemic disorders, and even excessive alcohol and tobacco consumption. Folk knowledge on medicinal plants and phytochemicals in the treatment of oral mucosal lesions has gained special attention among the scientific community. Thus, this review aims to provide a brief overview on the traditional knowledge of plants in the treatment of oral mucosal lesions.

Effects of low-level laser therapy on burning mouth syndrome.

To investigate low-level laser therapy (LLLT) applied to treat burning mouth syndrome (BMS). This prospective, comparative, partially blinded, single-centre, clinical trial of GaAlAs Laser, with 815 nm wavelength, included 44 BMS patients divided randomly into three groups: Group I (n = 16): GaAlAs laser 815 nm wavelength, 1 W output power, continuous emissions, 4 s, 4 J and fluence rate 133·3 J cm ; Group II (n = 16): GaAlAs infrared laser, 815 nm wavelength, 1 W output power, continuous emissions, 6 s, 6 J and fluence rate 200 J cm ; Group III (n = 12) placebo group, sham laser. All groups received a weekly dose for 4 weeks.

Influence of years of professional experience in relation to the diagnostic skill of general dental practitioners (GDPs) in identifying oral cancer and precancerous lesions.

Objective: To evaluate skill in diagnosing cancer and oral precancerous lesions among general dentists in the Autonomous Community of Murcia (Spain).

Material And Method: Twenty randomly distributed clinical images were used, of which 45% corresponded to benign lesions, 35% to oral precancerous lesions, and 20% to oral cancer. Each case was accompanied by a summarised clinical history.
