Prevalence of dentine hypersensitivity among university students in Turkey

Background and Objective: Dentine hypersensitivity (DH) is a common clinical finding with a wide variation in prevalence values. There is lack of data on the prevalence of dentinal sensitivity in Turkish population. The aim of this study was to establish the prevalence of DH and to examine some associated factors such as initiating stimuli among university students in Kýrýkkale, Turkey.Materials and Methods: A cross-sectional survey was conducted among undergraduates of University of Kýrýkkale, Turkey. An electronic questionnaire was developed and distributed via e-mail to undergraduate students in Kýrýkkale University. Self-administered questionnaire elicited information on demography, self-reported dentinal sensitivity, thetrigger factor, professional treatment taken, and duration time. Test of significance was done with Chi square statistics. P<0.05 was considered as significant.Results: A total of 1463 responses were evaluated in this study. One hundred and twenty-four students were diagnosed as having DH, giving a prevalence figure of 8.4%. The prevalence of DH in females was significantly higher than that in males. The most common initiating factor was cold drinks. Tooth sensitivity was found to be common among hardtoothbrush users. About 46% of patients reported that they had not undergone any treatment for the discomfort and 35% reported having had some sort of treatment. Among the participants with dentinal sensitivity, 58.8% of the respondents reported that they use soft drinks occasionally. Approximately 64.2% of the patients claimed that DH was present for1–6 days and the majority (87%) of the patients with hypersensitive teeth experienced pain occasionally.Conclusion: The prevalence of DH among university students was 8.4%. DH is not a common problem in undergraduate university students

Unilateral fusion of mandibular permanent lateral incisor with canine: A report of a rare case

Fusion is a developmental anomaly which occurs due to a union of one or more adjacent teeth during morpho-differentiation of the dental germs. Early diagnosis of this condition is important because it may cause clinical problems, such as esthetic concerns and arch asymmetry. These anomalies may be unilateral or bilateral and may affect either dentition, although the deciduous teeth are more commonly affected. This report describes a rare case of unilateral fusion between the mandibular permanent lateral incisors and the canine. Only few cases have been previously reported in the English literature. Hence this article aimed at reporting a case of this rare condition and evaluating the presence of any associated pathology

Prevalence of Dentine Hypersensitivity among Adult Patients Attending a Dental Hospital Clinic in Turkey

Objectives: The aim of this study is to determine the prevalence of dentine hypersensitivity (DH) and to examine some associated factors such as the initiating stimuli among adult patients attending the Restorative Clinic of the Kırıkkale University Dental Faculty, Turkey. Methods: Questionnaires for 1169 patients, 678 men and 491 women, were completed and necessary clinical examinations performed during a one-year period and patients who were diagnosed with DH were questioned further about their occupation and smoking habits. Patients with at least two different quadrants which had sensitive teeth with sound exposed cervical dentine on the facial surface, were included in the study. The amount of cervical lesions, buccal gingival recession and initiating factors associated with the sensitive teeth were also recorded. Results: Of the 1169 patients examined, 89 were diagnosed as having dentine hypersensitivity, giving a prevalence of 7.6%. The commonest teeth affected were the upper premolars and the commonest initiat-ing factor was cold drinks. Conclusions: The prevalence of dentine hypersensitivity in a postgraduate clinic in Turkey was 7.6%. The commonest teeth affected were the upper premolar and the commonest initiating factor was cold drinks.

A prospective, randomized, double-blind clinical trial of one nano-hybrid and one high-viscosity bulk-fill composite restorative systems in class II cavities: 12 months results

Hamidi, Mehmet Mustafa/0000-0003-3461-7925; Colak, Hakan/0000-0001-8262-0913WOS: 000407814700008PubMed: 28791976Background: Recently, manufacturers have introduced bulk-fill composite resins that reportedly can be placed in increments of 4 mm or greater. Objective: The purpose of this article was to report the results of 12 months prospective randomized clinical trial that evaluated the clinical performance of one high-viscosity bulk-fill composite resin in Class II cavities of posterior teeth. Materials and Methods: Thirty-four participantshad at least two Class II cavities included the study. Class II cavities restored with either a Tetric EvoCeram bulk-fi fill or universal nano-hybrid resin composite (Tetric EvoCeram). A total of 74 restorations (37 with each material) on 34 patients were placed according to the manufacturers' instructions by one calibrated operator. Results: Seventy restorations were evaluated after 12 months evaluation period. No postoperative sensitivity, anatomic form, retention, and secondary caries were observed after 6 and 12 months. Regarding the items color match, marginal discoloration, and marginal adaptation, the statistical analysis did not detect any statistical significance between two materials (P 0.05). Conclusion: After 12 months of clinical service, all restorations evaluated for both materials were classified as ideal, receiving predominantly Alfa scores for all parameters analyzed. Clinical Relevance: This study presents that high-viscosity bulk-fill resin composites (RCs) perform just as well as nano-hybrid RCs with the 2 mm RC layering technique, therefore could be alternative to conventional nano-hybrid RCs

Radiographic evaluation of the prevalence of enamel pearls in a sample adult dental population

Hamidi, Mehmet Mustafa/0000-0003-3461-7925; Colak, Hakan/0000-0001-8262-0913; ERCAN, Ertugrul/0000-0002-4753-6553WOS: 000341967500022PubMed: 24563448AIM: Enamel pearls are a tooth anomaly that can act as contributing factors in the development of periodontal disease. Studies that have addressed the prevalence of enamel pearls in populations were scarce. The purpose of this study was to evaluate the prevalence of enamel pearls in the permanent dentition of Turkish dental patients by means of panoramic radiographs. PATIENTS AND METHODS: Panoramic radiographs of 6912 patients were examined for the presence of enamel pearls. All data (age, sex and systemic disease or syndrome) were obtained from the patient files and analyzed for enamel pearls. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. RESULTS: Enamel pearls were detected in 5.1% of subjects and 0.85% of the teeth examined. Prevalence of enamel pearls was higher in males (6.58%) compared to females (3.96%). The mandibular first was the most commonly affected tooth. Enamel pearls were significantly more common in the mandibula compared with the maxilla (81.2% cf 18.8% respectively, p = 0.000). No statistically significant differences were found between the right-side and left-side occurrences. CONCLUSIONS: With the prevalence of 5.1% among the Turkish population, every possible effort should be made for locating of this anomaly especially in molars because it might be useful for prevention periodontal problems

Investigation of prevalence and characteristics of mesiodens in a non-syndromic 11256 dental outpatients.

PubMed: 24142619To investigate the prevalence of mesiodens in a sample of Turkish dental patients and their distribution among genders. A retrospective study was performed using panoramic radiography of 11256 patients, who ranged in age from 15 to 55 years old. All data (age, sex and or syndrome) were obtained from the patient files and analyzed for mesiodens. Statistical evaluation of the presence of mesiodens related to gender was performed by the Pearson chi-squared test. Mesiodens was detected in 15 subjects (0.13%). The prevalence of mesiodens for females and males was 0.20% and 0.057%, respectively (p = 0.037). The most commonly observed mesiodens was maxillary canine-like type (60%). Most of the mesiodens (67%) were found in the vertical position, followed by horizontal position (33%). The age and sex distribution, number of mesiodens per patient, shape, direction, size, and effect on permanent maxillary incisors are also presented in this study. The most common complication caused by mesiodens was midline of the permanent incisors. Mesiodens is an uncommon developmental anomaly in Turkish dental patients. Early diagnosis allows the most appropriate treatment, often reducing the extent of surgery, orthodontic treatment and possible complications

An analysis of the aetiology, prevalence and clinical features of dentine hypersensitivity in a general dental population

Hamidi, Mehmet Mustafa/0000-0003-3461-7925; Colak, Hakan/0000-0001-8262-0913WOS: 000307486400016PubMed: 22913162AIM, Dentine hypersensitivity may be defined as pain arising from exposed dentine typically in response to chemical, thermal or osmotic stimuli that cannot be explained as a rising from any other form of dental defect or pathology. The aim to this cross-sectional study was to determine prevalence of dentine hypersensitivity (DH) and to examine some associated etiological factors in a study of patients visiting general dental practitioners in Turkey. PATIENTS AND METHODS, A total of 1368 patients were examined for the presence of cervical dentine hypersensitivity by means of a questionnaire and intraoral tests by (air and probe stimuli). The patients have at least two different quadrants which have sensitive teeth with sound exposed cervical dentin on the facial surface were included the study. RESULTS, A total of 285 teeth were diagnosed as having dentine hypersensitivity in 73 patients, giving an overall prevalence figure for dentine hypersensitivity of 5.3%. 40-49 years age group was the cohort with the greatest number of subjects with DH and females had more predilection than males. Upper premolars were most affected and the commonest initiating factor was cold drinks. Subjects who smoked did not have more sensitive teeth on average than subjects who did not smoke (p > 0.05). Approximately half of the patients reported DH for a duration of within 1-3 days. The commonest etiological factor with the sensitive teeth was the gingival recession. CONCLUSIONS, The prevalence of dentine sensitivity in this sample was lower compared to studies carried out previously in different populations both general practice and hospital clinics. Further larger scale studies are required to assess its prevalence in Turkish population
