Brief summary
The aim of the study is to compare the effect of toothpastes containing thermal water of Castera-Verduzan with 1450 ppm fluoride and without fluorinated derivatives on oral hygiene, gingivitis, and dentin hypersensitivity in young adults.
Detailed description
This will be a double-blind, randomized, two-arm parallel-group study of the effect of toothpastes containing thermal water of Castera-Verduzan with 1450 ppm fluoride and without fluorinated derivatives. The groups will include adults with gingivitis and dentinal hypersensitivity (DH) diagnosed clinically. To assess the effect of the toothpastes, the following parameters will be used: gingival health (modified gingival index, MGI; gingival bleeding index, BI), dentin sensitivity (Shiff's index, VAS), oral hygiene level (Navi-Rustogi index), and salivary pH.

Masking description
The allocation concealment will be performed using sealed containers numbered by a third party (person who will not participate in the study). The toothpastes in white bottles without any titles will be placed in the containers. Each patient will receive a sealed container with a toothpaste on enrolment. Neither patients nor researchers will be aware of the type of the toothpaste used.

Inclusion criteria
* aged between 20-25 years * signed an approved Informed Consent Form, authorizing the participation in the trial and the use of the results of the trial for educational purposes and for the publication * the diagnosis of gingivitis stated clinically * at least one tooth with the diagnosis of dentin hypersensitivity stated clinically
Exclusion criteria
* medical and pharmacotherapeutic histories that may compromise the protocol (pregnancy or breastfeeding, psychiatric disorders, allergies to toothpastes ingredients, eating disorders) * systemic conditions that are etiologic to dentin hypersensitivity (e.g., chronic acid regurgitation) history of chemotherapy or radiotherapy * taking antibiotic, anti-inflammatory, or anti-coagulant medications 4 weeks prior to or after the baseline visit * oral mucosa pathology * periodontal surgery in the preceding 3 months * orthodontic appliance treatment within previous 3 months * teeth or supporting structures with any other painful pathology or defects * taking any other agents for DH management 4 weeks prior to or after the baseline visit * extensively restored teeth and those with restorations extending into the cervical area * dental bleaching within previous 3 months * subject withdrawal of consent * subject is not compliant with study procedures * adverse Event that in the opinion of the Investigator would be in the best interest of the subject to discontinue study participation
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of gingival inflammation by Modified Gingival Index (MGI) | 4 weeks after the baseline | MGI is used to assess visual symptoms of gingivitis on facial and lingual surfaces of each scorable tooth (whole mouth). Two scores are recorded buccally/labially, two scores lingually/palatally. Values are presented as means across all tooth surfaces with minimum and maximum scores in agreement with minimum and maximum index values (i.e., 0-4). Scoring is performed using standard dental light:0=absence of inflammation,1=mild inflammation;slight change in color,little change in color; little change in texture of any portion of the marginal or papillary gingival unit,2=mild inflammation; criteria as above plus the entire marginal or papillar gingival unit,3=moderate inflammation;glazing, redness, edema, and/or hypertrophy of the marginal or papillary gingival unit,4=severe inflammation; marked redness, edema and/or hypertrophy of the marginal or papillary gingival unit,spontaneous bleeding,congestion,or ulceration. Lower scores indicate better results. |
| Evaluation of gingival inflammation by Bleeding Inde | 4 weeks after the baseline | BI is used to assess bleeding elicited on probing as a measure of gingival condition. Gingivae are air dried and examiner assesses bleeding using a probe which is gently inserted into gingival crevice to depth of app 1 mm and run around tooth (angle of app 60 deg to long axis of tooth), gently stretching epithelium while sweeping from interproximal to interproximal along sulcular epithelium. BI is assessed on facial and lingual gingival surfaces of each scorable tooth (whole mouth). 3 scores are recorded buccally/ labially, 3scores lingually/ palatally. All scorable teeth in one quadrant are probed first (app 30 sec) before recording number of gingival units which bleed. Values are presented as means across all tooth surfaces with minimum and maximum scores in agreement with minimum and maximum index values (i.e., 0-2). BI score:0=no bleeding after 30 sec, 1=bleeding upon probing after 30 sec,2=immediate bleeding. Lower scores indicate better results. |
| Evaluation of DH according to Shiff sensitivity score | 4 weeks after the baseline | First, the tooth is isolated by the cotton roll from the adjacent teeth. Next, a blast of air from a standard dental unit syringe at 60 ± 5 psi at 18-22 °C is directed onto the exposed middle 1/3 buccal surface for 1 s at a distance of approximately 10 mm. Then, each patient reports the sensitivity he/she sensed using Schiff Cold Air Sensitivity scale scored from 0 to 3: score 0 means no response, score 1 means response without request of discontinuation of stimulus, score 2 means response with request of discontinuation of stimulus, and score 3 means pain with request of discontinuation of stimuli. Lower scores indicate better results. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of oral hygiene level according to Navi-Rustogi index | 4 weeks after the baseline | Nine sites per facial and lingual tooth surface are assessed, for a maximum 504 sites total (excluding 3rd molars, crowns, and surfaces with cervical restorations). Disclosed plaque is scored in each tooth area as follows: 0 = Absent; and 1 = Present. A mean plaque index (MPI) is calculated for each subject on a whole mouth basis. Lower scores indicate better results. |
| Evaluation of salivary pH | 3 minutes after baseline (after toothbrushing) | Unstimulated 5 ml whole saliva sample is collected in morning from 10 am to 11 am, two hours after the last meal. Participants refrain from eating, drinking, smoking, or conducting oral hygiene procedures for a minimum of 90 min prior to salivary collection. Participants are comfortably seated, are asked to avoid swallowing saliva and asked to lean forward and spit all the saliva they produced into a graduated test tube until the required volume is collected. The pH is determined immediately after the collection using a digital pH-meter. |
