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 Kırıkkale, Turkey. MATERIALS AND METHODS A cross-sectional survey was conducted among undergraduates of University of Kırıkkale, Turkey. An electronic questionnaire was developed and distributed via e-mail to undergraduate students in Kırıkkale University. Self-administered questionnaire elicited information on demography, self-reported dentinal sensitivity, the trigger 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 hard toothbrush 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 for 1-6 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.

Assessment of the Prevalence of Pulp Stones in a Sample of Turkish Central Anatolian Population

Objective. The aim of this study was to determine the prevalence of pulp stones (PS) in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly. Materials Methods. A retrospective study was performed using bitewing radiographs of 814 patients ranging in age from 15 to 65. All data (age, sex, and location) was obtained from the files. These patients were analyzed for pulp stones. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. Results. Of the patients, 462 (56.8%) were female and 352 (43.2%) were male. Sixty (12%) had one or more teeth that contained pulp stones. Pulp stones were identified in 518 (63.6%) of the subjects and in 2391 (27.8%) of the teeth examined. Pulp stone occurrence was significantly more common in the females than in males. With the increasing of age, the prevalence of pulp stones increased. Molars had statistically more pulp stones than premolars. Pulp stones were significantly more common in the maxilla compared with mandible. Conclusion. Prevalence of pulp stones in Turkish population was 27.8% but further larger-scale studies are required to assess its prevalence in the general population to compare it with other ethnic groups.

Radiographic study of the prevalence of dens invaginatus in a sample set of Turkish dental patients.

Aim: The aim of this study was to determine the prevalence of dens invaginatus in a sample of Turkish dental patients. Materials and Methods: The sample included 6, 912 panoramic radiographs from different Turkish dental patients. The ages of the patients ranged from 18 to 50 years. A tooth was considered having dens invaginatus if an infolding of a radiopaque ribbon-like structure equal in density to enamel was seen extending from the cingulum into the root canal. Maxillary and mandibular teeth were evaluated on panoramic radiographs to determine the type of dens invaginatus using Oehlers’ classification. Results: The overall incidence of patients with dens invaginatus was 0.17%. Dens invaginatus were detected in 15 teeth of a total of 192 150 teeth to give a tooth prevalence of 0.008%. Maxillary lateral incisors were most commonly affected teeth in the mouth (80% of cases), followed by maxillary canine teeth (20% of cases). The bilateral incidence of a symmetrical distribution was 25%. Conclusion: The occurrence of dens invaginatus among this Turkish population was rare. Attention should be paid to the presence of dens invaginatus and the treatment problems associated with it.

Incidence and distribution of pulp stones found in radiographic dental examination of adult Turkish dental patients.

Background: Pulp stones (PS) are discrete calcified masses found in the dental pulp, in the pulp tissue or become attached to or embedded into the dentine. The formation of pulp stones is still something of an enigma, leading to existence of some epidemiological gaps. Aim: To determine the prevalence and distribution of pulp stones in posterior tooth group by using panoramic radiograph. Materials and Methods: Panoramic radiographs from 6912 patients attending Kirikkale University Dental Faculty Hospital, Kirikkale, Turkey during the period from July 2009 to August 2011 were reviewed for the presence of pulp stones. The overall incidence of pulp stones in the patients and their correlations between female and male patients and between the right-side and left-side occurrences were analyzed by computer program, SPSS 15. (SPSS Inc. Chicago, USA) with using the χ2 test. Differences were considered as significant when P < 0.05. Results: Pulp stones were detected in 879 out of 6912 patients (person prevalence 12.7%). Pulp stones were detected in 2009 teeth out of a total of 96240 teeth to give a tooth prevalence of 2.1%. Their occurrence was higher in the maxilla than in the mandible for each tooth type. Pulp stones were found to involve the right side more (1224/2009) (61%) than the left side (785/2009)(39%) and they were significantly more common in females than males (P < 0.001). Conclusions: Attention should be paid to the presence of pulp stones and the treatment problems associated with them.

Yetişkin Türk toplumunda ağız yanması sendromu prevalansı

Objectives: Burning mouth syndrome (BMS) is defined as a chronic orofacial pain condition, characterized symptomatically by burning pain localized to the tongue and lips or may involve the entire oral cavity. The prevalence of burning mouth symptoms reported from international studies ranges from 0.6% to 15%. The aim of this study was to determine the prevalence of burning mouth syndrome in adult Turkish population. Materials and methods: A questionnaire was designed to collect data on demographic characteristics, medical history and drugs taken by the patients and clinical examination was performed. A cross-sectional study was carried out on 1000 (500 men and 500 women) randomly select

Analysis of Endodontic Complications Following Fixed Prosthodontic Rehabilitation

PURPOSE The aim of this study was to determine endodontic treatment needs and types of endodontic disease following fixed prosthodontic treatment 24 hours after tooth preparation, 1 week after tooth preparation, 1 month after placement, and 6 months after placement. MATERIALS AND METHODS Study groups consisted of patients who attended a university dental hospital department of prosthodontics for fixed prosthodontic treatment from January 2011 to December 2013. All teeth were clinically and radiographically evaluated according to American Association of Endodontists evaluation criteria before preparation. Metal-ceramic fixed partial dentures were placed for all patients. A total of 1,633 abutment teeth were prepared with 1,100 pontics in 524 patients (214 female and 310 male). Participant age, sex, and tooth number were recorded. Endodontic treatment follow-up was scheduled for 24 hours after tooth preparation, 1 week after preparation, 1 month after placement, and 6 months after placement, and all teeth were evaluated after placement of FPDs according to a modified criteria. RESULTS 2,733 retainers were placed with 624 FPDs. Of the FPDs, 332 (53%) were placed in the posterior and 196 (31.5%) in the anterior region. The remaining 96 FPDs (15.5%) were placed anteroposterior. The abutment/pontic ratio was 1.44:1. The number of retainers per FPD was 4.37. Of 1,633 abutment teeth, 103 were endodontically treated after placement of FPDs. Most observed endodontic disease was symptomatic irreversible pulpitis. There were statistically significant differences in terms of teeth regions (P < .001). When follow-up times of 24 hours, 1 week, 1 month, and 6 months were evaluated, there was no statistically significant difference among all teeth groups (P > .05). CONCLUSION A total of 2,733 retainers on 624 FPDs were evaluated over 6 months, and the mean endodontic treatment need ratio was 6.3%.

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.

The frequency and characteristics of talon cusps in a Turkish population

Background: The aim of this study was to determine the prevalence of talon cusps in a Turkish dental patient population with respect to sexes, jaws, and dental localization to determine the relation between sex and this anomaly. Materials and Methods: A cross-sectional study was carried out. Patients attending outpatient department of Restorative Dentistry Dental School, Kirikkale between October 2009 to January 2012 were screened specifically for the presence of talon cusp during routine outpatient screening. Each patient was examined clinically and radiographically for the presence of talon cusps. Results: A total 2597 sample was evaluated. Talon cusps were observed in 31 patients. Thus, the person prevalence of talon cusp was 1.2% in this study. Gender-wise prevalence was 1.25% and 1.13% in females and males, respectively. Talon cusps were detected in 44 teeth out of a total of 35424 teeth to give a tooth prevalence of 0.12%. Maxillary lateral incisors were most commonly affected teeth in the mouth, and most commonly seen type of talon cusp was type I (23 teeth, 52.3%). Conclusion: The prevalence of talon cusps was found to be 1.2% for the Turkish dental patient population. Clinicians should be aware of potential complications that may occur with talon cusps.
