Introduction: The aim of this study is to determine prevalence of oral diseases and oral surgical procedures at Department of Oral Surgery, Faculty of Dental Medicine, University in Sarajevo.Methods: The current study is retrospective analysis of oral surgical procedures performed from January 2011 to December 2012 at Department of Oral Surgery, Faculty of Dental Medicine, University in Sarajevo. The data were statistically analyzed by T-test of independent samples and using Chi-squared test. P value lower than 0,001 was considered to be statistically significant.Results: A total of 1299 patients were included in study. The age range is from 18 to 84 years, with mean age ± SD= 35±15 years. There were 42 different clinical diagnoses, and 13 diagnoses appeared in more than 1% of all patients. Impacted and semi-impacted teeth, periapical lesions and retained roots are the most frequent diagnoses and represent 68% of all diagnoses. Embedded and impacted teeth (35%) and diseases of pulp and periapical tissues (31%) are the most frequent diagnoses with respect of ICD-10. Impacted teeth is the most common diagnosis and removal of impacted third molars is the most common oral surgical procedure.Conclusion: Study points out variety of dentoalveolar patology and complexity of dental health care that often requires interdisciplinary approach in order to achieve optimal outcome for patient.

Introduction: Impaction may be defined as the failure of complete eruption into a normal functional position of one tooth within normal time due to lack of space in the dental arch, caused by obstruction byanother tooth or development in an abnormal position. The mandibular third molar is the most frequently impacted tooth. The incidence varies from 9.5% to 68% in different populations.Methods: The study was conducted in Department of Oral Surgery, Faculty of Dentistry, University in Sarajevo. Study represents retrospective analysis of panoramic radiographs (orthopantomograms) of patientsreferred to Department of Oral Surgery from January 2010 to February 2013 with indication for surgical removal of impacted third molars.Results: Of the 2000 radiographs, 761 presented with at least one impacted third molar (38%). A total of 1034 impacted mandibular third molars were present (51.7%). The most common age group was thirddecade (61.2%). Signifi cant statistical difference in incidence of third molar impaction was found between females and males (p<0.05), but there was no statistical difference in incidence in urban and suburbanpopulation (p=0.374). Vertical angulation was the most common pattern of impaction (65%). Frequency of third molars erupted into their normal position (class IA) was 42%. Impacted mandibular molars wereassociated with periodontal pockets in 134 (6.5%) cases and with dentigerous cysts in 5 cases (0.2%).Conclusion: The present study provides useful data regarding the clinical status of third molars in population of Bosnia and Herzegovina.

Svrha: Svrha istraživanja bila je pronaci poveznicu između eruptivnih stadija trecih maksilarnih i mandibularnih kutnjaka s lijeve i desne strane celjusti. Materijali i metode: Uzorak istraživanja ci- nilo je 529 ortopantomograma (OPG-a) – 264 (49, 9 %) pripadalo je muskom spolu, a 265 (50, 1 %) ženskom spolu u dobi između 8 i 25 godina. Sudionici su bili prema Olzeovoj metodi podijeljeni u sest dobnih skupina. Rezultati: Dobivene su visoke vrijednosti Spearmanova koeficijenta pove- zanosti između eruptivnih stadija lijevih i desnih maksilarnih i mandibularnih trecih molara. Izme- đu spolova nisu pronađene statisticki znacajne razlike u eruptivnim stadijima. Zakljucak: Prema dobivenim rezultatima za procjenu dentalne dobi u bosansko-hercegovackoj populaciji, preporu- cujemo Olzeovu metodu i trece mandibularne molare. Treba istaknuti da su moguce razvojne asi- metrije i da svaki dentalni antropolog mora biti svjestan te cinjenice. Svaka strana celjusti treba- la bi se posebno procjenjivati.

The aim of this cross-sectional retrospective study was to compare the accuracy of three radiographic methods for age estimation using orthopantomogram radiographs (OPGs) from developing children. OPGs of 2652 children (1214 boys and 1438 girls, aged 5.22–14.92 years) with 1474 children from Croatia and 1178 children from Bosnia and Herzegovina were examined and seven mandibular teeth from left side of mandible were assessed using Cameriere’s method by measurement of open apices in teeth, mineralization stages of four different teeth from right side of jaws using Haavikko’s adopted method based on Finnish children and Demirjian's mineralization stages of seven teeth from left side of mandible for Willems’ method with updated scoring based on Belgian children. The mean difference(±SD) in years between dental and chronological age (DA-CA) was calculated for each method. Results show that the most accurate method was by Cameriere (boys -0.08 ± 0.71, girls -0.03 ± 0.70 years), Haavikko’s method underestimated age more (boys -0.09 ± 0.80, girls -0.34 ± 0.75 years), while Willems’ method overestimated age (boys 0.51 ± 0.79, girls 0.28 ± 0.83 years). According to the analysis of variance, no statistically significant differences were found in results of DA-CA between children from Croatia and Bosnia and Herzegovina for each method. No statistically significant difference of DA-CA was found between boys and girls for Cameriere’s method, for Haavikko and Willems method there were statistically significant differences between genders. Statistically significant differences were found in results of DA-CA among different age groups for each method. Published results could be used in clinical, forensic and anthropological purposes when sample of children was used from specified countries.

The aims of this study were to evaluate adopted Haavikko method (1974) based on Finnish sample for dental age estimation in Bosnian-Herzegovian children and to create reference centile curves with LMS method for clinical, legal and forensic usage. Materials and methods In cross-sectional, retrospective study, the panoramic radiographs (OPGs) taken from 805 girls and 636 boys in Bosnia and Herzegovina, aged between 4 and 15 years, were studied. Method is based on scoring of four permanent teeth, 41, 44, 46, and 47 up to 10 years of age and and 13, 43, 44, and 47 in children over 10 years of age, with one of 12 mineralization stages. Dental age is than computed from the Haavikko’s tables as the mean of all four teeth. Kappa statistic and intraclass correlation coefficient (ICC) were used for testing intra- and inter-observer repeatability of mineralization stages and observed dental age by assessments of 10% (N=144) of OPGs. Results showed that Haavikko’s method underestimate the dental age in the BH children. Mean underestimation was -0.33 (SD 0.72) years in girls and -0.12(SD 0.82) years in boys. Cohen kappa scores were 0.79 for intra- and 0.80 for inter-observer agreement for mineralization stages and average measures for ICC for dental age were 0.98 for intra- and 0.90 for inter-observer agreement. In addition, 1st, 3rd, 5th, 50th, 95th, 97th and 99th centile curves of chronological age against the dental age were constructed for girls and boys separately using the LMS method by Cole and Green (LMS ChartMaker Software, Medical Research Council, UK), which could be used for age estimation in the BH children.
