A speech bulb obturator is a type of dental prosthesis that is used to help improve speech in individuals with velopharyngeal insufficiency, which is a condition often associated with a cleft palate. 

The appliance consists of an anterior part (similar to a retainer or denture base) and a posterior "bulb" that is custom-made to fill the gap between the soft palate and the pharyngeal walls during speech. 

This helps to achieve velopharyngeal closure, control nasal emission of air, and prevent nasal regurgitation of food and fluids during swallowing. 

The surrounding pharyngeal walls move to touch the bulb during speech, promoting functional competence.

Zinc phosphate cement is an anhydrous powder and liquid system, and its liquid (phosphoric acid) is very stable. Glass ionomer cement (GIC) liquid is polyacrylic acid, which is more prone to water loss or gain than zinc phosphate liquid. Polycarboxylate cement liquid is also polyacrylic acid, but it is typically supplied in a solution form that is highly susceptible to water evaporation when exposed to air, leading to changes in viscosity and handling properties. Therefore, polycarboxylate liquid has the highest rate of water loss, followed by GIC liquid, and then zinc phosphate liquid.

Carbonic anhydrase is present in the tubular cells and accelerates the reaction of carbon dioxide and water to form carbonic acid, which then dissociates into bicarbonate and hydrogen ions. This facilitates the reabsorption of bicarbonate into the blood and maintains the acid-base balance.
