Comparing the Effects of Different Cleansing Agents on the Shear Bond Strength of Resin Cements on Surface-Contaminated Zirconia: An In Vitro Study.

Background The long-term success and durability of any dental ceramic material depends on how well they adhere to the resin cements. Though sandblasting of zirconia with abrasive particles is one of the most commonly used techniques to enhance the bond strength, surface damage and phase transition may affect the mechanical properties of zirconia. Hence alternative surface treatment methods using chemical agents, lasers, and silicone coatings can be employed.

Facial Nerve Function and Hearing Following Facial Nerve Decompression for Traumatic Facial Nerve Palsy Through Posterior Tympanotomy Approach: A Descriptive Study.

To assess Facial Nerve function and hearing status among patients who have undergone facial nerve decompression via the Posterior tympanotomy approach for traumatic facial nerve palsy. A descriptive study was carried out in a tertiary referral centre. Patients with traumatic facial nerve palsy (HB VI) who underwent facial nerve decompression via posterior tympanotomy approach were enrolled in the study after at least 3 months of the surgery.

Congenital Cheek Salivary Fistula Associated with an Aberrant Parotid Duct System: Embryological Considerations and Surgical Repair.

Congenital cheek salivary fistula is a rare developmental anomaly with an abnormal connection between the parotid gland and the skin. An eight-year-old child presented with an opening on the right cheek, with intermittent saliva leakage aggravated during food intake and recurrent infections. Imaging studies had confirmed the diagnosis.

Assessment of acoustic characteristics of speech in patients with bilateral abductor vocal cord paralysis following trans oral carbon dioxide LASER posterior cordotomy.

Aims: The study aimed to assess voice quality in patients with bilateral abductor vocal cord paralysis (BAVCP) following transoral carbon dioxide (CO2) LASER posterior cordotomy with acoustic parameters.

Materials And Methods: Twenty-five participants were recruited over a three-year duration. Voice analysis was done twice, pre-operatively and three months post-operatively in decannulated patients, with the help of Praat software (Version 6.

Attenuated adenosine mediated immune-dampening increases natural killer cell activity in early age-related macular degeneration.

Non-exudative age-related macular degeneration (AMD) involves retinal pigment epithelium (RPE) dysfunction and has been linked to altered intraocular immunity. Our investigation focuses on immune cell subsets and inflammation-associated factors in the eyes with early and intermediate AMD. We observed elevated levels of activated natural killer (NK) cells and interferon-γ, concurrent with reduced myeloid-derived suppressor cells (MDSCs) and adenosine in AMD eyes.
