Opis:: Introduction and objective. Hyperdontia is a dental developmental anomaly in which supernumerary teeth exist. These are extra teeth to the normal set of primary or permanent dentitions. This article reviews the current literature on hyperdontia in the permanent dentition. Materials and method. A thorough literature search was carried out using Scopus, PubMed, and Google Scholar databases. Results were reviewed, prioritized, and findings compiled. The key words of the search strategy were: prevalence, case reports, supernumerary, supplemental, distomolars, forth molars, paramolars, parapremolars, mesiodens, and supernumerary lateral incisors. Only articles in English published in peer-reviewed journals were included. Brief description of the state of knowledge. The prevalence of supernumerary teeth varies between and within different populations. They may cause various aesthetic, occlusal, and functional complications and often require an interdisciplinary intervention. Familiarity with such anomalies is essential for the dental practitioner. Recognition and correct identification of the anomaly is important when communicating with other dental team members, especially in the case of a referral to or from another dental office. Moreover, understanding the anomaly is an important factor in determining the course of treatment, if any. Conclusion. It is hoped that this review will provide dental practitioners with an update on the classification, characteristics, and prevalence figures for each type of supernumerary tooth.

Opis:: Introduction. Cleft lip with or without cleft palate (CLP) is associated with hypodontia, supernumerary teeth, dysmorphology of the crown or root shape, teeth impaction and malposition. The prevalence of anomalies is higher than in general population. Objective. The aim of the review is description of dental anomalies affecting children with cleft lip or without cleft palate. Abbreviated description of the state of knowledge. The most common anomaly is teeth agenesis with prevalence of 28% – 66% of patients with CLP. Permanent dentition is more often affected (52.7%) than primary (16.2%), the cleft-side lateral incisor is most often missing. Hypodontia increases with severity of the cleft. Supernumeraries were found in 17.7% of the subjects with cleft lip and/or palate for primary maxillary dentition, and in 5.7% for permanent maxillary dentition. Supernumerary teeth are mostly maxillary laterals, both inside and outside the cleft, and have different variations in morphology and size. The anterior maxilla is a main area for supernumeraries occurrence. Lateral incisor in the cleft area is often peg-shaped, its microdontia was revealed in 5.6%; they can also have enamel hypoplasia – 8.9% of cases. Macrodontia was found in 12.5% and taurodontism in 15.2%. Canine impaction prevalence is different in studies from various cleft centres and ranged from 0% – 58%. Rotations of central incisors was found in the area of cleft in 86.7%. Transposition of maxillary canine and first premolars was found in 5.5% of bilateral, 8% of right, and 3.3% of left unilateral clefts in the study. Summary. Multiple teeth anomalies affect the population of children with cleft lip with or without palate. The most common problem is hypodontia. Treatment process of these patients demands experienced specialists in different fields of dentistry and complex, rigorous dental care.

Opis:: Head and neck cancers constitute the sixth most common malignant tumours worldwide, and are one of the majors problems of global public health. In the oral cavity there are several types of oral cancers, but around 90% are squamous cell carcinoma. Many different risk factors play a role in the etiology of head and neck cancer. The aim of this study is presentation from the aspect of molecular, viral and bacterial infection. Knowledge about all factors which influence the development of these malignances is essential for diagnostics and successful treatment.
