RESUMO
Excessive heat generation during bone drilling for dental implant placement is a known risk factor for bone necrosis and delayed healing. Therefore, it is of interest to evaluate the maximum change in temperature during and after preparation of the implant site for an implant diameter of 4.2 using gradual drilling and single drilling protocols. Hence, 26 artificial bone blocks with d1 density were divided into two groups where the group I had 13 sites prepared using a single drill and for group II bone blocks, 13 implant sites were prepared with the gradual drill protocol using 5 drills. The drill was done at room temperature with 1500 rpm using constant saline irrigation of 50ml/min. The maximum change in temperature was assessed using an intraoral camera. The data collected were statistically evaluated and results were formulated. Data shows that temperature change was significantly higher in group II where a gradual drill protocol was done compared to group I with a single drill protocol for placing the dental implant of diameter 4.2.Considering its limitations, the present in-vitro assessment concludes that a single drill protocol for preparing an osteotomy site for placing a dental implant of diameter 4.2 generates lesser heat than conventional gradual drilling protocols.
RESUMO
Background Alexithymia is a personality trait involving difficulties in emotional regulation (difficulties in identifying feelings, difficulties in describing feelings, and externally oriented thinking). It has a negative impact on health as it evokes poor personal hygiene, poor nutrition, and unhealthy behaviors in affected subjects. Identifying alexithymia in the dental setup is vital as it can compromise the patient-dentist relationship, especially in subjects neglecting oral hygiene. Aims The present study aimed to establish an association between alexithymia and dental neglect among adult subjects seeking dental care by using Dental Neglect Scale (DNS), and alexithymia was assessed on the 20-item Toronto Alexithymia Scale (TAS-20). Methods The present cross-sectional survey study included adult subjects of age 20 years or more. For all included participants, a structured questionnaire was given to assess dental neglect on demographic profile, six items of the DNS, and alexithymia was assessed on the 20-item TAS-20. The collected data were analyzed using a Chi-square test keeping significance at the p-value of <0.05. Results In 534 adult subjects, females had high scores for both TAS-20 and DNS along with their related factors. With higher education and increasing age, a significant increase in the mean TAS-20 scores and mean DNS scores was seen in the study participants (high mean DNS scores in females (19.55±3.98) compared to male subjects 19.36±4.34). TAS-20 scores were higher in females (59.31±10.78), factor 1 (DIF) (19.54±5.54), factor 2 (DDF) (15.46±4.05), and factor 3 (EOT) (24.34±4.64). Conclusion The present study, considering its limitations, concludes that there is no association between dental neglect and alexithymia in adult subjects seeking dental care. However, higher DNS and TAS-20 scores are seen in females showing them have difficult descriptions and identification of feelings in dental set-up increasing dental neglect among them.
RESUMO
BACKGROUND: Disturbances seen during tooth formation result in developmental dental anomalies presenting in the oral cavity. These anomalies manifest as discrepancies in the number, color, size, and shape of the teeth. These dental anomalies can either be acquired, congenital, or developmental. Their early detection and management are necessary as they affect aesthetics and occlusion. The study had the aim of gauging the prevalence of developmental anomalies in the permanent dentition of Indian subjects. METHODS: A total of 1192 participants recruited from the institute for study purposes, comprising males and females, were examined clinically and radiographically, and their dental casts were also evaluated. These subjects were assessed for anomalies in position, structure, number, and/or shape. Anomalies in the position include transmigration, transportation, and/or ectopic position; anomalies in the structure, including dentinogenesis imperfecta or amelogenesis imperfecta; anomalies in number, including hyperdontia or hypodontia; and anomalies in shape, including peg laterals, taurodontism, fusion, dens evaginatus, talon cusp, and/or microdontia. RESULTS: A statistically significant difference was seen in unilateral microdontia and dentinogenesis imperfecta between males and females, with attained p-values of 0.003 and 0.06, respectively. The results of the present study showed that 9.89% (n = 118) study subjects, whereas 1% (n = 12) study subjects had two dental anomalies in their permanent dentitions, with no subject presenting more than two dental anomalies, showing that various dental anomalies have a low prevalence in the Indian population. CONCLUSION: The present study has led to the conclusion that the prevalence of dental anomalies is low in Indian subjects. However, these anomalies should be detected and treated early to prevent them from causing further complications.
