Summary
Palato-radicular grooves (PRG) are anatomical variations found in teeth. This study investigated the prevalence and periodontal implications of PRG in maxillary incisors, revealing significant associations with periodontal health.
Area of Science:
- Dental Anatomy
- Periodontology
- Oral Health Research
Background:
- The palato-radicular groove (PRG) is a developmental anomaly that can affect tooth morphology.
- Understanding the prevalence and clinical significance of PRG is crucial for diagnosing and managing periodontal issues.
- Previous research has highlighted potential links between PRG and localized periodontal destruction.
Purpose of the Study:
- To determine the prevalence of palato-radicular grooves (PRG) in maxillary incisors.
- To investigate the relationship between the presence and location of PRG and periodontal parameters.
- To analyze the association between PRG and plaque accumulation, gingival inflammation, and probing pocket depth.
Main Methods:
- Examination of 404 maxillary lateral and central incisors from 101 individuals.
- Documentation of PRG presence at or apical to the cemento-enamel junction (CEJ) using clinical probing, flap surgery, and magnification.
- Classification of PRG location (mesial, distal, mid-palatal) and recording of plaque index (P1I), gingival index (GI), and probing pocket depth (PPD).
Main Results:
- The study identified and characterized palato-radicular grooves in the examined maxillary incisors.
- A significant association was found between the presence of PRG and specific periodontal conditions, including increased probing pocket depths.
- Analysis revealed correlations between PRG and factors such as plaque accumulation and gingival health status.
Conclusions:
- Palato-radicular grooves are present in maxillary incisors and can be associated with periodontal complications.
- The location of PRG may influence its impact on periodontal health, with grooves at or apical to the CEJ being of particular concern.
- Routine examination for PRG is recommended in patients presenting with localized periodontal problems in the anterior maxilla.

01:15Teeth
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 and...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:27The Oral Microbiota
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...
