Risk Factors Associated with Black Tooth Stain

Area of Science:

• Dental Science
• Nutrition Science
• Biochemistry

Background:

• Tooth discoloration is a common aesthetic concern.
• Dietary factors and saliva properties are potential contributors to tooth staining.
• Understanding these influences is crucial for preventative dental care.

Purpose of the Study:

• To investigate the association between food, drink, and drug intake and tooth discoloration.
• To identify specific dietary components linked to black tooth pigmentation.
• To explore the role of saliva characteristics in tooth discoloration.

Main Methods:

• Study involved 60 patients (15-25 years) divided into discolored (Group 1) and control (Group 2) groups.
• Data collected via questionnaires on intake habits.
• Analyzed elements in discoloration using atomic absorption spectrometry; assessed saliva buffer capacity and microbial presence (Streptococcus mutans, Lactobacillus spp.) using Caries Risk Test (CRT) kits.

Main Results:

• Significant differences observed in collard greens and beet intake between groups (p<0.05).
• Patients with pigmentation consumed less red wine (p<0.05) but showed no difference in drug intake.
• Pigmented teeth group was older, smoked more, had lower saliva pH, and lower Streptococcus mutans counts (p<0.05).
• Traces of calcium, magnesium, iron, copper, and zinc found in discoloration samples.

Conclusions:

• Dietary habits, particularly beet and collard green consumption, and red wine intake, are associated with tooth discoloration.
• Saliva properties, including pH and microbial composition, are important factors in tooth discoloration.
• Multiple factors, including diet and saliva, influence the formation of tooth discoloration.
