Cervical lesions are often characterized by defects seen in the gingival third of a tooth crown which may be in the facial or lingual surface. Pathological loss of tooth structure caused by factors other than dental caries such as cervical abrasion is referred to as non-carious cervical lesions (NCCL). Cervical abrasion is an example of NCCL in which a constant exposure of the tooth to mechanical forces leads to pathological wearing away of the hard tissues. In most of the cases, cervical tooth lesions are revealed to be more common as the age increases. Several studies have reported the difference in the prevalence of cervical abrasion between males and females. Many reports suggest that cervical abrasion is commonly associated with improper tooth brushing habits. To evaluate the prevalence of cervical abrasion between genders and its influence on age. It is a retrospective study conducted using the case records of Saveetha Dental College and Hospital, Chennai, India from June 2019 to March 2020. Data including the patient’s name, patient’s identification number (PID), age, gender and presence of cervical abrasion were retrieved from the patients’ case records. A total of 742 consecutive case records were retrieved and analysed. Cervical abrasion was observed in 371 individuals of this study. High prevalence of cervical abrasions was seen in males (70.9%) compared to females (29.1%). Most of the cases were observed in individuals within the 41-50 years age group (28.8%), and the least was seen within the 11-20 years age group (0.3%). Within the limits of the study, most of the cervical abrasion cases are recorded in individuals within the 41-50 years age group with higher predilection in males. There is a statistically significant association of cervical abrasion with age and gender.

Abstract Background: The "tooth morphology" course is an important basic stomatology course. But it is difficult to fully reflect the 3D morphological characteristics of tooth structure in the two-dimensional pictures in traditional textbooks. The aim of this study was to assess the effect of 3D-printed plastic model teeth in the teaching of tooth morphology. Methods: Forty-five undergraduate stomatology students who had matriculated at the Fourth Medical University in 2014 and 23 who had matriculated in 2016 were involved in the study. Each student who matriculated in 2016 was given a full set of 14 standard 3D-printed plastic model teeth for use during the learning process, and an anonymous questionnaire was used to evaluate the 3D-printed plastic model teeth from the perspective of the students. Results: There was no significant difference in the scores of the theoretical examination and the total score between the two groups. However, for the score of the sculpted gypsum teeth, students who used the 3D-printed plastic model teeth in their studies scored significantly higher (P=0.002). More than 90% of the students thought that the 3D-printed plastic model teeth were of great help or were very helpful for mastering the anatomy of teeth and for carving the plaster teeth.Conclusion: The standard 3D-printed plastic teeth can effectively assist students in learning tooth morphology by transforming the two-dimensional pictures and descriptions in the textbook into a 3D conformation, effectively promoting students' learning and mastery of tooth morphology and structure. Additionally, the results suggest that the 3D-printed plastic teeth are of great help to the students in mastering and improving their carving skills.

Each student who matriculated in 2016 was given a full set of fourteen standard 3D-printed plastic model teeth for use during the learning process, and an anonymous questionnaire was used to evaluate the usefulness of the 3D-printed plastic model teeth from the perspective of the students.
