Which tooth has least attached gingiva?

The percentage of gingival groove The highest percentage of gingival groove on the oral aspect was found in relation to the right upper premolarspremolarsThe premolars, also called premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. They have at least two cusps.https://en.wikipedia.org › wiki › PremolarPremolar – Wikipedia (31%), and the least was found in the right lower molars (4%).

Where is attached gingiva thinnest?

The thinnest gingiva was noticed at permanent newly erupted incisors (0.72 ± 0.36; P < . 001). Thickness of attached gingiva positively correlated with its width and with probing depth (r = 0.164, P < . 001).

What is lack of attached gingiva?

Generalized lack of attached gingiva is a major criterion of periodontal Ehlers-Danlos syndrome. A. In healthy individuals a band of thick and keratinized gingiva (*) provides mechanical protection. It is tightly and unmovably bound to the periosteum via collagen type I fibers.

Where is attached gingiva thickest?

The gingival thick- ness was found to be maximum in central incisor and minimum in canine in both the groups. However, the width of keratinized gingiva was found to be maximum in lateral incisor in group 1 (pigmented) and central incisor in group 2 (nonpigmented) and minimum in canine in both the groups.

Where can attached gingiva be found?

The gingiva surrounds the teeth and the marginal parts of the alveolar bone, forming a cuff around each tooth. It can be divided into the free gingiva, which is closely adapted to the tooth surface, and the attached gingiva, which is firmly attached to the underlying periosteum of the alveolar bone (Figs 4.3, 4.4).

What tooth has the greatest width of attached gingiva?

The width of attached gingiva

On the buccal aspect, the greatest width of attached gingiva was found in relation to the upper lateral incisors (right: 5.86 mm, left: 5.45 mm) and the narrowest zone was observed on the first lower premolars (right: 2.37 mm, left: 2.42 mm) (Table 1).

Where is enamel the thinnest?

Enamel varies in thickness over the surface of the tooth and is often thickest at the cusp, up to 2.5 mm, and thinnest at its border, which is seen clinically as the cementoenamel junction (CEJ) .

What is the difference between attached gingiva and unattached gingiva?

Attached gingiva – This tissue is adjacent to the free gingiva and is keratinized and firmly attached to the bone structure. It can range from 3-12 mm in height. Free gingiva – This tissue is not attached and forms a collar around the tooth.

How is minimal attached gingiva measured?

Place your probe on the outside of the tissue and measure from the gingival margin to the mucogingival junction. Now measure the sulcus or pocket depth (probing depth). Subtract the probing depth from the outside measurement of the gingiva, and you will have the width of attached gingiva.

Which has the least width of attached gingiva?

It is generally greatest in the incisor region (3.5 to 4.5 mm in the maxilla and 3.3 to 3.9 mm in the mandible) and less in the posterior segments, with the least width in the first premolar area (1.9 mm in the maxilla and 1.8 mm in the mandible).

What is the difference between free gingiva and attached gingiva?

Which tooth has the most attached gingiva?

On the oral aspect of mandibular teeth, the highest width of attached gingiva was found in relation to lower second molars (right: 5.74 mm, left: 5.48 mm) and the narrowest zone was observed in the area of central incisors (right: 3.41 mm, left: 3.32 mm) (Table 1).

What is the minimum width of attached gingiva?

[14] The width of attached gingiva varies in different areas of the mouth and have been given a range of 1–9 mm,[15] 1–4 mm,[16] 0–g5 mm. [17] In the present study, the range of the mean width of attached gingiva varied from 1 mm to 4 mm.

What is the strongest tooth in your mouth?

Molars

Molars: Your molars are your twelve back teeth—six on top and six on bottom. They are your strongest and widest teeth. They have a large, flat surface with deep ridges to help grind food and finish chewing before swallowing.

Which tooth has the thickest enamel?

Our data confirm previous findings that females have thicker enamel, enamel thickness is greater on larger teeth, molars' enamel thickness increases with molar number and enamel thickness increases when going from first to second to third molars.

Where is enamel the thickest?

cusp

Enamel varies in thickness over the surface of the tooth and is often thickest at the cusp, up to 2.5 mm, and thinnest at its border, which is seen clinically as the cementoenamel junction (CEJ) .

What is free vs attached gingiva?

The attached gingiva is firmly bound to the periosteum and to the dentition. The free gingiva is that portion of the unattached gingiva around the cervical region of each tooth; the interdental gingiva (papilla) fills the space between them.

Which tooth has the greatest width of attached gingiva?

On the oral aspect of mandibular teeth, the highest width of attached gingiva was found in relation to lower second molars (right: 5.74 mm, left: 5.48 mm) and the narrowest zone was observed in the area of central incisors (right: 3.41 mm, left: 3.32 mm) (Table 1).

What is the difference between free and attached gingiva?

Which of the following regions of the dentition has the narrowest width of attached gingiva?

The narrowest widths of attached gingiva were invariably found in the region of the mandibular first bicuspid and cuspid while the broadest widths were associated with the maxillary lateral and central incisors.

Is free gingiva attached?

How much attached gingiva is essential?

Lang and Loe5 advocated a minimum of 2 mm of gingiva (1 mm free gingiva and 1 mm attached gingiva) to maintain gingival health, as teeth with less than 2 mm exhibited clinical signs of inflammation, even in the presence of good oral hygiene.

What is the sharpest human tooth?

Canines

Canines. Next to the lateral incisors are our canines, which are the sharpest and longest teeth in our mouths.

What tooth has the longest root?

canine roots

The canine roots are the longest root of all teeth. Furthermore, the upper canines have longer roots when compared to the mandibular canines. The canines serve to support the incisors.

What is the sharpest tooth?

Canines

Canines. Next to the lateral incisors are our canines, which are the sharpest and longest teeth in our mouths.

Which is more harder enamel or dentin?

However, judging from the measured hardness values, enamel was considered harder than dentin. Therefore, enamel has higher wear resistance, making it suitable for grinding and crushing foods, and dentin has higher force resistance, making it suitable for absorbing bite forces.
