Summary
Gingival recession, the apical migration of the gum line, may be linked to gingival thickness. This study found a weak negative correlation between thicker gums and recession, suggesting a potential protective factor.
Area of Science:
- Dentistry
- Periodontology
- Oral Health
Background:
- Gingival recession involves the apical migration of the gingival margin, exposing tooth roots.
- Etiological factors include periodontitis, aggressive brushing, oral piercings, and prior orthodontic treatment.
- Recession prevalence increases with age and can result from combined etiological factors.
Purpose of the Study:
- To investigate the correlation between gingival thickness and the occurrence of gingival recession.
- To determine if gingival thickness is a significant factor in gingival recession.
Main Methods:
- Fifty-five subjects (aged 18-35) participated in the study.
- Buccal gingival thickness was measured on incisors, canines, and bicuspids under local anesthesia.
- Statistical analysis included Pearson Correlation Coefficient and linear regression using STATA 10.1.
Main Results:
- A weak negative correlation (Pearson Correlation Coefficient = -0.216) was observed between gingival thickness and gingival recession.
- Linear regression analysis yielded a statistically significant p-value of 0.025.
Conclusions:
- A weak negative correlation exists between gingival thickness and gingival recession.
- Thicker gingival tissue may offer some protection against recession, though other factors likely play a significant role.

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
