Summary of article contents:
Introduction
Supernumerary teeth, or hyperdontia, are defined as an excess number of teeth present beyond the normal dental formula. Their prevalence ranges between 1% to 4% in permanent dentitions, and they can be categorized based on position and form as eumorphic or dysmorphic. Eumorphic teeth resemble normal teeth in morphology, while dysmorphic teeth exhibit irregular shapes. The etiology of supernumerary teeth is not fully understood but may involve factors such as genetic predisposition and local dental lamina hyperactivity. This paper presents a rare case of a supernumerary eumorphic fifth mandibular incisor in association with localized aggressive periodontitis, aiming to encourage further studies on this unusual condition.
The Rare Association of Supernumerary Eumorphic Teeth and Periodontitis
The reported case involves a 25-year-old Indian Muslim man diagnosed with localized aggressive periodontitis and simultaneously identified as having a supernumerary eumorphic fifth mandibular incisor. The fifth incisor was morphologically similar to the existing mandibular incisors, with no signs of fusion between roots and crowns visible clinically or radiographically. In this instance, the presence of the supernumerary tooth was uncommon, given that such occurrences in the mandibular incisor region account for only 2% of hyperdontia cases. Additionally, the relationship between supernumerary teeth and aggressive periodontitis has been hinted at in earlier studies, but no direct connection has been confirmed, indicating this specific occurrence is especially rare.
Conclusion
The association between supernumerary eumorphic mandibular incisors and localized aggressive periodontitis represents a unique case in the dental field. Although both conditions are uncommon, their simultaneous presentation raises questions about potential genetic or environmental relationships. While some studies have suggested a link between supernumerary teeth and aggressive periodontitis, the current case emphasizes the need for more extensive research to explore any biological connections definitively. Further genetic investigations could elucidate the mechanisms underlying these anomalies and potentially improve understanding and management of such dental conditions.
FAQ section (important questions/answers):
What is the prevalence of supernumerary teeth in permanent dentitions?
The prevalence of supernumerary teeth ranges from 1% to 4% in permanent dentitions, with the mandibular incisor region having the lowest prevalence at 2%.
What are eumorphic and dysmorphic supernumerary teeth?
Eumorphic supernumerary teeth resemble normal teeth in morphology, while dysmorphic ones are typically small, conical, or irregular in shape, such as odontomes.
Is there a known association between supernumerary teeth and aggressive periodontitis?
Yes, a possible association has been reported between supernumerary teeth and localized aggressive periodontitis, although this connection is considered rare and may not be biological.
What factors contribute to the development of supernumerary teeth?
Although the exact etiology is unknown, theories include tooth bud dichotomy, hyperactivity of the dental lamina, and potential hereditary factors.
What was unique about the case reported in the study?
The case featured a rare supernumerary eumorphic fifth mandibular incisor associated with localized aggressive periodontitis, without any fusion or identifiable familial association.
Glossary definitions and references:
Scientific and Ayurvedic Glossary list for 鈥淪upernumerary mandibular incisor linked to aggressive periodontitis鈥�. This list explains important keywords that occur in this article and links it to the glossary for a better understanding of that concept in the context of Ayurveda and other topics.
1) Study (Studying):
The keyword 'Study' refers to the systematic investigation aimed at exploring the rare association between supernumerary eumorphic mandibular incisors and localized aggressive periodontitis. This case report serves as an important contribution to existing literature, highlighting atypical dental phenomena that warrant further academic investigation and understanding.
2) Family:
The keyword 'Family' is relevant as the case stresses the hereditary aspects of dental anomalies. While the presented individual did not exhibit familial supernumerary teeth, previous studies suggest that such conditions can have genetic components, thus indicating the importance of familial associations in understanding dental conditions.
3) Bleeding:
The term 'Bleeding' is significant as it is one of the primary complaints reported by the patient, pointing towards the clinical manifestations of localized aggressive periodontitis. This symptom is crucial for diagnosis, correlating with the observed periodontal deterioration associated with supernumerary teeth.
4) Indian:
The keyword 'Indian' identifies the demographic context of the reported case. This highlights potential geographic and ethnic variations in dental anomalies and periodontitis, suggesting the necessity for localized studies that can address unique risks and presentations pertinent to different populations.
5) Shami (Sami, S膩m墨, S膩mi, 艢am墨, 艢ami, Sam墨):
The keyword 'Sami' refers to a researcher cited in the paper who has contributed to understanding genetic links to supernumerary teeth. His findings on homozygosity-mapping provide insights into potential genetic underpinnings affecting the prevalence of dental anomalies in specific populations, enhancing the scholarly discussion.
