Introduction. The aim of study was to correlate dental-pulp reactions to dental caries with diverse localization, evolution and depth. Materials and method. The study was realized on a group of 87 patients with age ranging between 15-35 years. 222 posterior teeth with carious lesions were examined both on clinical and radiographs (ortopantomographs). Type of pulp-dentinal defensive reactions visible on radiographs were as follows: neodentinogenesis with advanced deposition of tertiary dentin, dentinal hypermineralisation, difuse pulp calcification. Parameters taken in study were as follows: sex, age group, dental group, radiographic indices (depth, location). Data were recorded in tables and expressed in Microsoft Excel graphs. Results and discussions. Clinical and radiographic data showed correlation between deep chronic caries localized on occlusal surfaces of mandibular molars and dentinal hypermineralisation reactions; deep chronic caries localized on maxillary molars were associated with massive retraction of pulp room through neodentinogenesis. Lack of pulp-dentinal complex reactions was observed especially for patients with age 15-25 and dental caries with acute evolution. Conclusions. Age, localization and evolution of dental caries can be correlated with presence of specific forms of pulp-dentinal reactions.
