NCT ID: NCT06122597 Active, not recruiting - pH Clinical Trials

A Clinical Trial to Evaluate the Efficacy of ConcenTrace to Buffer pH Levels Within the Body.

Start date: October 5, 2023
Phase: N/A
Study type: Interventional

This virtual single-arm trial will last 12 weeks. Participants will take the drops daily and complete questionnaires at Baseline, Week 4, Week 8, and Week 12. Urine pH measurements will be taken at Baseline, Week 4, Week 8, and Week 12 using pH test strips.

NCT ID: NCT05852145 Not yet recruiting - Dental Plaque Clinical Trials

Oral Changes With Caloric and no Caloric Sweeteners

Start date: October 2023
Phase: Phase 1/Phase 2
Study type: Interventional

The objective of this clinical trial is to compare the effect that the intake of beverages without sweetwners, added with non-caloric sweeteners (stevioside) and caloric sweeteners (sucrose) on oral pH and dental biofilm microbiome in Mexican adolescents. Participants will drink on different occasions a beverage without sweetener, a beverage added with stevioside or a beverage added with sucrose. The researchers will compare the changes that each one causes in salivary pH, dental biofilm pH, dental biofilm bacterial proliferation and dental biofilm microbiome.

NCT ID: NCT05746949 Completed - Oxygen Clinical Trials

Comparison of the Effects of High-flow Nasal Cannula Oxygen and Jet Ventilation Techniques

Start date: February 18, 2023
Phase: N/A
Study type: Interventional

Endoscopic microsurgical procedures of the larynx (direct examination-bx, microlaryngeal resection) require the anesthesiologist and surgeon to work in the same area throughout the procedure, and while ventilation is provided during the procedure, small diameter endotracheal tubes are preferred to see the surgical area as easily as possible. However, it is sometimes observed that even conventional endotracheal tubes of this diameter make surgery difficult by obstructing the view. On the other hand, apneic laryngoscopy techniques used in upper airway surgeries, such as microlaryngoscopy and laryngotracheal surgery, where the airway is shared by the anesthesiologist and surgeon, have been replaced by safer and controlled high-frequency jet ventilation applications due to the risk of hypoxemia and hypercapnia. In recent years, oxygenation has come to the fore with Transnasal High Flow Insufflation (OptiflowTM - Fischer & Paykel Healthcare, Auckland, New Zealand), an apneic oxygenation method. This randomized study aimed to compare the effects of high-flow nasal oxygen and jet ventilation on oxygenation in patients receiving general anaesthesia for endolaryngeal surgery.

NCT ID: NCT05437874 Completed - Dental Plaque Clinical Trials

Carbonated Beverage Consumption in pH and Bacterial Proliferation

pHSB
Start date: January 18, 2018
Phase: Phase 1
Study type: Interventional

The objective of this research is to evaluate the oral modifications caused by different types of coke drinks (regular coke and diet coke). The salivary and the dental biofilm pH will be determined in the first minutes after their consumption. Additionally, the bacterial proliferation of dental biofilm will be evaluated.

NCT ID: NCT04717778 Completed - pH Clinical Trials

Comparison of Salivary pH After Consuming Milk of Origin Vegetable vs Cow's Milk in Children

Start date: January 13, 2020
Phase: N/A
Study type: Interventional

The study was carried out in 21 first grade primary school children, 100% aged 6 years, 52.4% were female. They were given 5 types of milk, each one was measured on different days (Monday cow's milk, Tuesday coconut milk, Wednesday almond milk, Thursday soy milk, Friday rice milk)

NCT ID: NCT03934515 Completed - pH Clinical Trials

End-Tidal CO2 (etCO2) and pH in the Correct Naso-gastric Tube Placement

NGT
Start date: November 1, 2020
Phase:
Study type: Observational

The laying of a naso-gastric tube is an extremely common event in intensive medicine; although standard naso-gastric tube laying is performed at the patient's bedside, this procedure is not without risk. Through the use of methods already used in the clinical field, of daily use, we want to identify the threshold value between tracheal and esophageal etCO2 (group A) and the threshold value between gastric and esophageal pH (group B).

NCT ID: NCT03877874 Not yet recruiting - pH Clinical Trials

The Impact of Anti- Asthmatic Medications on Salivary pH and Dental Caries Pattern in a Group of Egyptian Children With Bronchial Asthma

Start date: July 2021
Phase:
Study type: Observational

The impact of Anti- Asthmatic medications on salivary pH and dental caries pattern in a Group of Egyptian Children with Bronchial Asthma.

NCT ID: NCT03612414 Completed - Quality of Life Clinical Trials

Efficacy of a Dietary Supplement (Aqualief®) in Xerostomic Patients

Aqualief
Start date: June 15, 2016
Phase: N/A
Study type: Interventional

Xerostomia is defined as the subjective complaint of dry mouth. Symptoms of dry mouth may range from mild oral discomfort to significant oral disease that can compromise patients' health, dietary intake and quality of life. Xerostomia is accompanied by numerous signs and symptoms mainly in the mucous membranes, lips, tongue, salivary glands and teeth. This study was designed to verify efficacy and safety of a novel dietary supplement (Aqualief),designed with the aim of stabilizing the saliva flux and pH at a neutral level and to improve the acid buffering capacity of saliva.

NCT ID: NCT03526770 Completed - Oral Hygiene Clinical Trials

Comparison of 5 Buffering Agents on Changes in Salivary pH in Individuals Previously Exposed to a Test Carbonated Drink

SALPH-C
Start date: May 28, 2018
Phase: N/A
Study type: Interventional

The diurnal variation in the flow of saliva and hence the composition of saliva is an established fact. Consumption of acidic and sweetened food and beverage is known to reduce the salivary pH and some of them reduce it to critical pH levels and result in structural damage to the hard tissues of the tooth. The purpose of this study is to ascertain the effect of the select commercially available test carbonated drink containing sugar on the salivary pH and assess the buffering capacity of the saliva with or without various intervention measures following the exposure to the test carbonated drink at different time intervals.

NCT ID: NCT03513575 Completed - Oral Hygiene Clinical Trials

Comparison of 5 Buffering Agents on Changes in Salivary pH in Individuals Previously Exposed to a Test Flavoured Milk

SALPH-M
Start date: May 1, 2018
Phase: N/A
Study type: Interventional

The diurnal variation in the flow of saliva and hence the composition of saliva is an established fact. Consumption of most types of acidic and sweetened foods and beverages are known to reduce the pH of saliva and some of them even reduce it to critical pH levels and result in structural damage to the hard tissues of the tooth. The purpose of this study is to ascertain the effect of the selected commercially available test sweetened flavored milk drink on the salivary pH and assess the buffering capacity of the saliva with or without various intervention measures following the exposure to the test flavored milk drink at different time intervals.
