Revascularization or Apexification: Treatment of Choice in Non Vital Teeth- A Case Report of 2 Teeth

Asian Journal of Dental Sciences, Page 6-13

Alternatives like apexification or revascularization can be performed for the treatment of non vital teeth in young permanent teeth. Apexification with Mineral trioxide aggregate (MTA) is the best alternative but it has the limitation of high cost and non-reinforcement of root canal dentin. So a new material Biodentine bioactive calcium silicate-based cement has been recently launched in the dental market as a ‘dentin substitute’ which claims improvements of some of the properties such as physical qualities and handling. Nowadays regeneration of tissues is the emerging and exciting field in the health sciences rather than replacement with artificial substitutes. Pulp revascularization depends on the ability of residual pulp and apical and periodontal stem cells to differentiate. However, both the methods i.e., apexification and revascularization are effective regarding the narrowing of the apical foramen of an immature tooth.

Asian Journal of Dental Sciences, Page 14-19

Natal and Neonatal teeth area unit though not common tooth development process anomalies. They are oftentimes a section of teeth anomalies. The prevalence has been determined between one in 2000 to 3500 live births. The aim of this paper is to report a case of a ten- day old baby with natal teeth in mandibular anterior region associated with ulceration on ventral surface of the tongue. Clinical presentation disclosed natal teeth with no mobility within the mandibular anterior region and Riga–Fede disease. The treatment plan was to extract the natal teeth followed by surgical operation of the extraction socket to forestall aspiration, swallowing of teeth, and for early resolution of lesion. Satisfactory healing of lesion was resolute at ten days follow up visit.

Asian Journal of Dental Sciences, Page 1-5

Background: Medicine and dentistry need to go hand in hand for holistic betterment of a patient. However, in India even today the medical practitioners are unaware of a very important specialty of dentistry which is Oral Medicine and Radiology which deals with oral manifestations of systemic diseases.

Aim: Therefore, this study was conducted to assess and increase their awareness.

Study Design: A validated questionnaire consisting of closed ended questions was sent to 100 medical practitioners and they were asked to tick the most appropriate response.

Results: Among the 100 doctors, 55% were aware of the specialty and the remaining 45% were not aware of the specialty in dentistry. It was also observed that even though the medical practitioners encountered oral medicine specialty cases like Temporo-mandibular joint disorders, orofacial pain, premalignant lesion etc. they referred them elsewhere due to lack of awareness.

Conclusion: There is a pressing the need to improve the coordination between medical and dental practitioners.

Asian Journal of Dental Sciences, Page 20-28

Introduction: Soft tissue calcifications are categorized into dystrophic, metastatic and idiopathic calcifications. The current aim of the study was to analyze the prevalence of soft tissue calcifications in head and neck region using digital dental panoramic radiography.

Materials and Methods: A cross-sectional retrospective study with digital panoramic radiographs of 500 dental patients who visited the Oral Radiology department from November 2018 to January 2019 were analyzed for soft tissue calcifications.

Results: The most common soft tissue calcification identified were submandibular sialolith 37.5%, followed by 25% of calcified stylohyoid ligament, 12.5% of phlebolith and 12.5% of  tonsillolith 12.5% Carotid artery Calc  ification

Conclusion: The prevalence of soft tissue calcifications was low which increases with age. Soft tissue calcification occurs more common in male than in female. Once a soft tissue calcification is diagnosed incidentally in a routine dental radiograph it can aid in prevention of the disease.

Analysis of Radiographic Signs to Predict the Risk of Damage to the Inferior Alveolar Nerve Following Impacted Mandibular Third Molar Extraction among Sinhalese Population

L. H. M. I. M. Herath, S. Padma Silva, A. Dharmapala

Asian Journal of Dental Sciences, Page 29-43

Aims: This study aimed to define the panoramic criteria can be used in predicting the direct contact between impacted mandibular third molar (MTM) and the inferior alveolar nerve (IAN).

Study Design: A prospective cross-sectional study.

Place and Duration of Study: This study carried out at Unit B in National Dental Teaching Hospital, Ward Place, Colombo 07 from July 2019 to February 2020.

Methodology: Both orthopantomography (OPG) and cone beam computed tomography (CBCT) images of 107 impacted MTMs were assessed to record the radiographic signs for each impacted tooth. The angulation and the position of impaction, Rood & Shehab signs including superimposition, mandibular canal (MC) position relative to the MTM roots, proximity of MTM roots to MC, and the changes of cortical plates due to impacted MTM roots were recorded with sex and age. The Chi-square and Fishers’ exact tests were used for comparison.

Results: The most common position of impaction was position B, most common impaction angulation was mesial angulation, most common OPG sign was interruption of white line, and most common MC position was lingual position relative to the MTM roots. Position A, and position B, A-vertical impaction type, B-horizontal impaction type, darkening of roots, sign combinations of darkening and superimposition, and darkening and interruption, and lingually located MC relative to the MTM roots were significantly correlated with direct contact between impacted MTM and the MC (P<0.05). The signs of superimposition and narrow root were significantly correlated with lingually positioned MCs (P<0.05). The sign of darkening of roots was significantly correlated with lingual and buccal cortical plates thinning (P<0.05).

Conclusion: With superimposition and darkening or darkening and interruption, or B-horizontal type of impaction, there is a risk of IAN damage during the surgical removal of impacted MTM. With A-vertical type of impaction, there was no risk of damage to IAN. The sign combination of superimposition and darkening has a high positive predictive value for predicting contact MTM roots to MC than buccal plate thinning.
