Concomitant Crown Dilaceration and Concrescence in Maxillary Incisors following Trauma to their Primary Predecessors: A Case Report.

Developmental disturbances in the permanent dentition are commonly seen due to traumatic injuries to the primary teeth, especially intrusive and avulsion injuries of the overlaying primary incisors. These disturbances may range from enamel discoloration or hypoplasia, crown/root dilaceration, odontoma-like malformation and eruption disturbances. Concrescence is extremely rare in anterior teeth. This case report describes a rare case that showed a concrescence of the unerupted maxillary right lateral incisor and maxillary central incisor with crown dilaceration. Awareness regarding early diagnosis and the consequences of untreated trauma to primary teeth should be emphasized.

Reliability of Educational Content Videos in YouTubeTM about Stainless Steel Crowns.

The purpose of the present study is to evaluate the quality and educational information provided on YouTubeTM about stainless steel crowns (SSC). Videos were searched for on YouTube TM using keywords related to stainless steel crowns in pediatric dentistry in the Google Trends application. A total of 52 videos were available. After exclusion criteria application, 22 videos were selected for the study for analysis. To classify the video content as high or low quality, a scoring system formed of seven parameters was used. For a global evaluation of the video quality, the video information and quality index were applied. Data obtained were analyzed statistically. Only a few videos explained the importance of SSCs. Most of the videos uploaded with a high number of likes were of low quality. Very few videos were of high quality. The content quality and educational quality of videos is poor and incomplete. None of the videos explained the need for the SSC and its benefits in pediatric dentistry.

Prevalence of Missing First Permanent Molars in a Selected Population in a University Dental Clinic Setting: A Retrospective Radiographic Study.

AIM AND OBJECTIVE: This study aimed to determine the prevalence of missing first permanent molars (FPMs) in the 7-29-year-old selected population of Al Ahsa, Saudi Arabia. MATERIALS AND METHODS: This study retrospectively analyzed 398 panoramic radiographs of patients aged from 7 to 29 years old for missing FPM. Patients were divided into two age-groups: 7-15 and 16-29 years old. Study variables including gender, age, missing FPM, dental arch, and right or left sides of the arch were recorded. The data were statistically analyzed using Chi-square tests. RESULTS: Of the total study sample, 23.1% of patients had only one missing FPM, 13.3% of patients had two, and 2.8% of them had three missing FPM teeth. No patient had four missing FPM teeth. A total of 60.8% (242) radiographs in the overall sample did not show any missing teeth. The mandibular FPMs (35.2%) were found missing more frequently than their maxillary counterparts (17.4%) and the left mandibular quadrant showed a higher rate of missing FPM (21.9%). No statistically significant association was seen between the missing FPM and the gender or age-group (p > 0.05). CONCLUSION: The high prevalence rates of missing FPM in the study population warrants attention. Further prospective studies are needed to comprehensively evaluate the effect of early loss of the FPM on space changes in the arch and subsequent reduction in complex orthodontic treatment needs.
