Oral Malodor Examination Tool

Understanding the causes of oral malodor through measurement values

Most oral malodor is related to "odor gases" produced by bacteria
Oral Chroma measures odor gases separated into 3 types
We combine test results with oral condition to develop an improvement plan

The most prominent gas indicates the likely direction of the cause

Hβ‚‚SHydrogen Sulfide

Main source

Produced by bacteria in tongue coating

Odor character

Sulfurous odor

  • Strongly linked to tongue coating β€” White deposits on the tongue surface are the main source
  • Increases with oral dryness β€” Saliva's cleansing and antimicrobial action weakens
  • Often worse upon waking and when fasting β€” Increases during periods of reduced saliva
  • Increases when stress reduces saliva β€” Influenced by the autonomic nervous system
  • Closely related to tongue cleaning habits β€” Changes with frequency and method of cleaning

Tongue deposits are the raw material for odor gases. Gentle tongue cleaning and maintaining saliva flow are the cornerstones of management.

CH₃SHMethyl Mercaptan

Main source

Produced by bacteria in inflamed and bleeding areas within periodontal pockets

Odor character

Odor associated with gum inflammation

  • Strongly linked to periodontal disease β€” Inflammation of periodontal tissue is the source
  • Increases with bleeding and deep pockets β€” More noticeable with greater inflammation
  • Associated with a putrid odor β€” A reference for characteristic odor type
  • Linked to calculus and gingival swelling β€” Tend to become breeding grounds for bacteria
  • Filling and crown margins also contribute β€” Check areas where deposits accumulate

Gum inflammation and bleeding are the raw material for bacteria. Periodontal basic treatment and reviewing self-care are central to management.

(CH₃)β‚‚SDimethyl Sulfide

Main source

Also check extra-oral influences from nasal, throat, and general health conditions

Odor character

Odor requiring extra-oral cause evaluation

  • Extra-oral influences also checked β€” Nasal, throat, and general health are also reviewed
  • Nasal/throat symptoms, health status, medications also checked β€” Assess post-nasal drip and dryness
  • Reviewed in combination with intraoral causes β€” Comprehensive assessment
  • Association with post-nasal drip and congestion also checked β€” Influence of deep nasal odor
  • Identifying bothersome situations and times is also important β€” Helps clarify lifestyle context

In addition to intraoral conditions, nasal, throat, general health, and medications are checked as needed.

Why Use Support Care Products?

🦷Why use support care?

When deposits or dryness are present in the mouth, odor-causing conditions can develop more easily.

DepositsοΌ‹ DrynessοΌ‹ Missed areas= Oral environment prone to imbalance
  • There are areas a toothbrush cannot easily reach
  • Deposits may also remain around the tongue and gums
  • Dryness makes the oral environment more prone to imbalance
  • Combining daily care routines makes it easier to maintain the environment

Support care products are used alongside daily cleaning to help maintain the oral environment.

πŸ’§Role of Poic Water (Mouth Rinse)

Prepare the mouth before cleaning for easier care

Poic Water is used as a rinse before brushing to prepare the mouth and make tooth brushing and tongue care easier.

  • Prepares the entire mouth before cleaning
  • Helps condition the surface of tongue coating and plaque
  • Easy to combine with brushing, interdental cleaning, and tongue care
  • Not intended to mask odors

Especially recommended for: Those with heavy tongue coating / prone to dry mouth / bothered by morning odor / undergoing periodontal treatment

This product alone will not resolve the condition. Use in combination with brushing, interdental cleaning, and gentle tongue care.

🌱Role of Probiotic Tablets

Use after cleaning to help balance the oral environment

Probiotic tablets are used as a supplement to help balance the oral flora. Consistent daily use is important.

  • Using after cleaning makes it easier to support the oral environment
  • Important to use as a habit rather than a one-time fix
  • Aims to create an environment where odor-causing deposits are less likely to remain

Especially recommended for: Those who want to stabilize their oral environment

Tablets alone will not eliminate oral malodor. Use in combination with periodontal treatment, oral hygiene instruction, and tongue care.

πŸ“‹Recommended routine

2Brush, clean between teeth, gentle tongue care

4Retest under same conditions

First prepare the mouth, then remove deposits, and finally support the balance of the oral environment.

No single product should be used alone β€” consistent use combined with daily cleaning is what matters.
