Article Synopsis
- The text introduces a rare case of a patient with both benign and malignant jaw lesions simultaneously, highlighting the scarcity of such instances in existing literature.
- The patient has right maxillary squamous cell carcinoma and several benign odontogenic cystic lesions, which also align with Gorlin-Goltz syndrome characteristics.
- The study emphasizes the importance of understanding management and follow-up strategies by reviewing relevant literature on similar cases.
Posttraumatic and postsurgical sensory disturbance is a known complication of almost all zygomaticomaxillary (ZMC) complex fractures involving the infraorbital nerve, for which few treatments are effective. Our study used neurosensory assessments to evaluate the efficacy of melatonin on pain and nerve healing following ZMC surgery. Sixty-four randomly allocated ZMC fracture patients were prophylactically administered either oral melatonin or an identical placebo for 15 consecutive days.

When the amplitude of the high-frequency force is tuned, the resultant vibrational resonance is used to detect the low-frequency signal and also to enhance it into a high-frequency signal. Further, we also show that even when the low-frequency signal is changed from sine wave to square and sawtooth waves, vibrational resonance can be used to detect and enhance them into high-frequency signals.

- Haemangiomas are benign vascular tumors that commonly occur in infants and can develop in the oral cavity.
- Various treatment options exist for haemangiomas, including sclerotherapy, embolisation, laser surgery, and cryotherapy, with cryotherapy being noted for its effectiveness and ease of use.
- The text presents a case of a young patient with multiple oral cavity haemangiomas that did not respond to medical treatment, highlighting the successful application of cryosurgery.
Ascorbic acid (AA) and eugenol (EUG) are well-known antioxidants found in several fruits, spices and herbs. In particular, the EUG, one of the major phytocompounds present in clove, acts as pro-oxidant or anti-oxidant depending on its concentration. Considering the medical importance of AA and EUG and its extensive usage in the form of food and medicine, we have developed a voltammetric sensor based on hydroxyapatite-TiO composite modified GCE for their selective and simultaneous determination over very wide linear range of 2.
