Unlabelled:
Children with hypertrophic tonsils and adenoids may have adverse effects on dental occlusion, which tend to worsen during the growth period. Diagnosis and early treatment is essential.
Aim:
Prospective clinical study to compare the cephalometric measurements before and after adenotonsillectomy in mouth breathing patients.
Material And Method:
We had 38 patients of both genders, aged between 7 and 11 years in our sample, broken down into: oral group, 18 patients with obstructive hypertrophy of pharyngeal tonsil and/or palate grade 3 or 4; control group, 20 patients with normal breathing. Angular and linear dental measurements were compared between the groups in a 14 months interval. We used the "t" Student and Wilcoxon tests for unpaired samples, at 5% significance, for statistical purposes.
Results:
The sagittal position and axial angle of the lower incisors increased significantly in the group with oral breathing, the sagittal position of the upper incisors increased significantly in the oral group, which still had a significant increase in overbite.
Conclusion:
Adenotonsillectomy was very effective in improving some dental measurements, with benefits to growing patients preventing malocclusions from becoming difficult to treat or permanent.

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...

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

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.
