1. Mandibular bone is more dense, maxilla is less dense. 2. Maxillary roots are more tapered than mandibular teeth. 3. In maxilla sinuses are present that may even be visible in some Periapical xrays. 4. Teeth anatomy or maxillary and mandibular teeth is different. 5. Number of roots in the posterior teeth vary in both the jaws.

The function of the pulmonary sinuses is to separate both of the semilunar cusps that are in the pulmonary trunk valve. They forma think wall between the two.
The concavity that forms on the mesial aspect of maxillary first premolars is called the cuspid groove. It is the result of the first premolar having both a buccal and palatal root. The groove functions as an alignment guide for the maxillary cuspid as it descends into the mouth.
After a storm once, a large eucaliptus branch broke off, and my roomate and I brought it inside our tiny dorm room. By about 3am, we both had nasty headaches, and had to drag the branch outside. I think our sinuses were very open, but at a price!

If your sinuses are sore and you feel like your left ear (or both ears) is blocked, it means that your sinuses are probably congested. When your sinuses become blocked or congested, they create pressure in your head and can even lead to ear infections. This happens because your sinuses are connected to your ears via the eustachian tube. It is important that you treat sinus congestion as it can develop into a sinus infection or ear infection. There are a wide variety of treatments that you can use including: Saline solutions (salt water) Remedies (SinusWars7) Nasal Sprays (Sinol) Personally I prefer the sinuswars remedies (homeopathic). They are natural and didn't have any side effects.
A lingual pit on the lingual surface of a maxillary molar is at an increased risk for cavities, due to both increased biofilm retention and thinness of enamel forming the walls of the pit. Enamel sealants are recommended to be used on the lingual surfaces of erupting teeth, although sealants have been shown to not bond as easily on lingual surfaces as they do on the occlusal surfaces.
if you get a real bad sinus infection it can make your face have swelling both sides of your face can be involved i have seen it in one side and i seen it in both sides and it can become very painful to have to deal with
The pterygomaxillary fissure serves as a passageway for both vascular and neural structures. The maxillary artery and its branches, which supply blood to the facial structures, run through this fissure. Additionally, the infraorbital nerve, a branch of the maxillary nerve (V2), passes through the pterygomaxillary fissure to provide sensory innervation to the face.
Most obvious structure formed by contributions by two bones in your hard palate. Behind that you have the soft palate. Major and anterior part of the hard palate is formed by palatine process of the maxilla bone. On posterior or back side, you have the palatine bone.
The sinuses and ears are connected through the Eustachian tube, which helps regulate pressure and drain fluids. Issues in one area can affect the other, leading to problems like ear infections or sinusitis. Proper functioning of both is important for overall health and well-being.
