Objectives. Specialty literature review on the issue of the chronologically delayed eruption. Examples of the approached subject by the presentation of two clinical cases of different aetiologies. Introduction. The process of teeth eruption lasts for approximately 13-15 years, during which period primary and permanent teeth erupt successively, at moments placed around the medium eruption time. Physiological chronological variations of teeth eruption are situated in the interval of +/- twice the standard deviation from the medium eruption age (calculated on large population groups). Delayed/accelerated eruptions are considered pathological teeth eruptions that take place far beyond the limits of this interval. Material and method. The cases of two patients, of age 9 and 10, are presented. Both suffer of delayed dental eruption, of different aetiology, mixed in the firs case and local in the second one. Diagnosis was established by the thorough evaluation of the familial and personal history, the general, facial and oral clinical examination; which led to the elaboration of the individualised treatment scheme. Diagnosis sequence and treatment methods adapted on the specific situation were established. Results and conclusions. Large deviations from the medium teeth eruption standards alert the paedodontist, which must thoroughly investigate the patient
