Introduction As non‐carious cervical lesions (NCCLs) may compromise aesthetics and function, knowledge of their aetiological covariables enhances management of clinical complaints and success of restorative treatments. Aims The primary aim of this study was to assess the presence of NCCLs among the general population of the Republic of Srpska, Bosnia and Herzegovina and the potential association with patient‐related risk factors. Methods A prevalence study of NCCLs included 738 respondents from eight towns/municipalities. Two dental practitioners examined all respondents. NCCLs were diagnosed according to the Smith and Knight tooth wear index, measured using a Williams periodontal probe. Data regarding risk factors were obtained through a structured questionnaire. Multivariate logistic regression was used to analyse the association of risk factors and the occurrence of NCCLs. Results Non‐carious cervical lesions were diagnosed in 384 (52%) respondents. Multivariate regression analysis showed that several variables were independently associated with the risk of developing NCCLs, including frequent consumption of acid food (P = 0.001), frequent consumption of acid drinks (P = 0.001), retaining drink in the mouth (P = 0.001), alcohol consumption (P = 0.030), bruxism (P = 0.018) and gastro‐oesophageal reflux (P = 0.023). First mandibular premolars were the most affected teeth (left: 46.0%; right: 44.0%), followed by the second right maxillary premolars (37.3%), second left maxillary premolars (33.6%) and finally by the first right maxillary premolars (34.0%). Conclusion The results of the current study suggest that NCCLs occur frequently and have a multifactorial aetiology. The lowest prevalence was recorded among individuals younger than 20 years of age. As the majority of risk factors are modifiable, regular dental care could lead to the early detection of NCCLs.

SummaryDiabetes mellitus is one of the most common chronic diseases which continue to increase in number and significance. It presents the third most prevalent condition among medically compromised patients referring for dental treatment. Diabetes mellitus has been defined as a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Hyperglycemia leads to widespread multisystem damage which has an effect on oral tissue. The present article summarizes current knowledge regarding the association between diabetes mellitus and oral and dental health.

E. faecalis is more prevalent than P. gingivalis in primary endodontic infection. Intracanal medication in conduction with instrumentation and irrigation efficiently eliminates E. faecalis and P. gingivalis from infected root canals.

Summary : Introduction The aim of this study was to determine dental status and prosthetic rehabilitation in elderly population in relation to socioeconomic factors in Republika Srpska. Material and Methods The study included 262 subjects (133 males and 129 females) aged 65-74 years. Dental status was assessed using DMFT index and its components (D - decayed, M - extracted, F - filled tooth) and analysed in relation to socioeconomic factors: gender, level of education and monthly income. Prosthetic restorations were recorded for both jaws in accordance with criteria of the World Health Organisation. Results The mean DMFT was 27.2. Females had the highest DMFT index score (29.1) while highly educated subjects had the lowest score (22.7). The mean number of missing teeth was 22.7. There were 28.2% edentulous respondents. Significant difference in the number of edentulous persons was recorded in relation to gender, education and monthly income. In total, 16.8% of subjects had functional dentition (≥20 natural teeth). 48.5% and 32.1% of elderly respondents were found to have at least one form of prosthetic restoration in upper and lower jaw, respectively. Complete dentures were the most common prosthetic restorations. Conclusion Socioeconomic factors influenced dental status in elderly population. Removable dentures were more common restorations compared to crowns and bridges.

The study indicates that there is a relationship between poor control of diabetes and caries, and periodontal disease.
