The aim of this study was to compare the pulpal reactions after exposure due to trauma and/or caries and to suggest the appropriate treatment options for the management of pulp, in the light of the histological findings in the primary teeth. Fifteen primary maxillary incisors with pulpal exposure were examined with light microscope in a blind study. After the histological evaluation, teeth were divided into three groups for the etiological factors due to the exposure according to the patient's files: trauma group, caries group and caries and trauma group. The inflammatory infiltration was diminished from the pulp chamber towards the apical third of the root canal in all of the examined teeth. Teeth in the trauma group presented fewer inflammatory cells in the root canal in comparison with other groups. It was concluded that the teeth with traumatic pulp exposure were considered as more likely to respond positively to pulpotomy technique. Pulpectomy or extraction seemed to be indicated for the decayed or decayed and traumatically injured teeth.

D007180	Incisor	Any of the eight frontal teeth (four maxillary and four mandibular) having a sharp incisal edge for cutting food and a single root, which occurs in man both as a deciduous and a permanent tooth. (Jablonski, Dictionary of Dentistry, 1992, p820)	Incisors
D008437	Maxilla	One of a pair of irregularly shaped bones that form the upper jaw. A maxillary bone provides tooth sockets for the superior teeth, forms part of the ORBIT, and contains the MAXILLARY SINUS.	Maxillae,Maxillary Bone,Bone, Maxillary,Bones, Maxillary,Maxillary Bones,Maxillas
D011670	Pulpectomy	Dental procedure in which the entire pulp chamber is removed from the crown and roots of a tooth.	Pulpectomies
D011671	Pulpitis	Inflammation of the DENTAL PULP, usually due to bacterial infection in dental caries, tooth fracture, or other conditions causing exposure of the pulp to bacterial invasion. Chemical irritants, thermal factors, hyperemic changes, and other factors may also cause pulpitis.

D011672	Pulpotomy	Dental procedure in which part of the pulp chamber is removed from the crown of a tooth.	Pulpotomies

D003731	Dental Caries	Localized destruction of the tooth surface initiated by decalcification of the enamel followed by enzymatic lysis of organic structures and leading to cavity formation. If left unchecked, the cavity may penetrate the enamel and dentin and reach the pulp.

D003789	Dental Pulp Exposure	The result of pathological changes in the hard tissue of a tooth caused by carious lesions, mechanical factors, or trauma, which render the pulp susceptible to bacterial invasion from the external environment.	Exposure, Dental Pulp,Pulp Exposure, Dental
D003790	Dental Pulp Necrosis	Death of pulp tissue with or without bacterial invasion. When the necrosis is due to ischemia with superimposed bacterial infection, it is referred to as pulp gangrene. When the necrosis is non-bacterial in origin, it is called pulp mummification.
