Introduction: Diabetes is a common disease that may have some influence on sensory nerves. The aim of this study was to evaluate dental pulp responses to 2 pulp sensibility tests (ie, cold and electric) in patients with type 2 diabetes compared with healthy individuals.

Methods: Three hundred twenty-two premolar teeth in 51 patients who had type 2 diabetes and 347 premolar teeth in 53 individuals with no medical conditions were investigated. The patients with type 2 diabetes were unified and had fasting plasma glucose <300, hemoglobin A1C <10, less than a 10-year history of diabetes mellitus, and no history of hypertension. Electric and cold pulp sensibility tests were performed for all teeth. The cold test results were recorded by the Heft-Parker visual analog scale, and the electric pulp test results were recorded based on the pulp tester's grade that evoked a response.

Results: There was no statistically significant difference between upper and lower premolar teeth in healthy individuals compared with the patients with diabetes in response to the cold and electric pulp tests (P > .05). In the patients with diabetes, the response of their upper premolars to the cold test was significantly reduced in diabetic patients >45 years of age (β = -1.15, P = .013). However, there was no significant correlation between the cold test and age in the lower premolars of both diabetic and nondiabetic participants (P > .05). There was also no significant correlation between the need for a higher number of the electric pulp test current to evoke a response in maxillary and mandibular premolars of the patients with diabetes and nondiabetic participants with age (P > .05).

Conclusions: There was a significant correlation between the reduction of maxillary premolar teeth responses to the cold test in diabetes patients >45 years of age.

First birth cesarean proportion: A missed indicator in controlling policies.

Background: Around one out of two mothers give births by cesarean section (CS) surgery in Iran and about half of this number is due to previous CS. Recently Health Sector Evolution (HSEP) program (started in April 2014) targets the high rate of CS in Iran. To assess the impact of the interventions, we emphasized that the First Birth Cesarean (FBC) proportion is one of the main indicators to assess the controlling programs.

Methods: Data on the mode of delivery were collected in Kerman province between 21 March and 20 March 2015 classified by hospital ownership. FBC proportion is defined as the number of CS in the first pregnancies divided by the total number of first births. Chi-square test for trend was used to assess the trends.

Results: Total number of births was around 34000. There were 8.9 and 13.1 percent reduction in CS and FBC proportion respectively. CS proportion was 54.5 at the end of the first quarter of the studied period and reached to 49.6 at the end of the period (p<0.0001). Also, FBC proportion was 54.1 percent at first and reached to 47 percent at the end of the study period. The main reason for CS was due to previous CS. At the hospital level, the highest reduction in CS and FBC proportion were in public hospitals.

Conclusion: RESULTS suggested more reduction in FBC proportion than the CS proportion, so this is a very good sign since more potential CS cases will be prevented. As repeated CS is one of the main indications for the operation, in the short term, even effective policies may change the overall proportion slightly, while the FBC proportion is more sensitive to reflect the impacts. Therefore, it is necessary to target the main fuel to reduce CS proportion effectively.
