ABSTRACT
Maxillary sinus odontogenic keratocyst (OKC) is very rare and occupies less than 1% of the total OKC cases reported in the literature. OKCs have characteristic features that are unique compared to other cysts of the maxillofacial region. Considering their peculiar behaviour, varied origin, debated development, discourse treatment modalities, and high recurrence rate, OKCs have been a subject of interest for various oral surgeons and pathologists globally. This case report presents an unusual case of invasive maxillary sinus OKC into the orbital floor, pterygoid plates, and hard palate in a 30-year-old female. The case report confers that cystic maxillary sinus lesions should always be treated very extensively irrespective of the nature of the lesion as the site makes it highly susceptible to secondary infection and recurrence. The case also establishes a set of imaging modalities and specific treatment approaches to be followed for maxillary sinus OKC based on the literature of all the previous cases reported.
ABSTRACT
Mandibular first molars, also called six-year molars as they appear at around six years of age, are the first permanent teeth to erupt in the oral cavity. They are the teeth most commonly affected by dental caries. Anatomically, the tooth presents with two roots and three canals. In very rare cases, presence of an extra root or a supernumerary root has been associated with the tooth. When this root is present lingual to the distal root, it is called radix entomolaris whereas when it is present buccal to the mesial root, it is called radix paramolaris. The presence of veiled canals is possible due to variation in the anatomy of the tooth. It is therefore necessary to locate, prepare and obturate these hidden canals in order to achieve success in endodontic treatment.
ABSTRACT
Causative linkages of tobacco use with oral potentially malignant disorders and cancers of oral cavity have been studied. Oral squamous cell carcinoma is one of the most common cancers in India. The International Agency for Research on Cancer (IARC) monograph found a significant association between smokeless tobacco (SLT) use and oral cancer. However, only a few limited studies have been represented on the IARC monograph. Published meta-analyses have provided pooled risk estimates for oral cancers caused by tobacco, both on global and regional levels. This systematic review was aimed at summarizing all the available studies exclusively in India by collecting data from PubMed and Medline. Emphasis was laid on cohort and case-control studies, and a few cross-sectional studies for premalignant lesions were also discussed. A significant association was noticed on SLT and premalignant and malignant oral cavity lesions.
ABSTRACT
Dilaceration is one of the causes of maxillary central incisor eruption failure. If the dilacerated maxillary permanent central incisor is in a horizontal or vertical position and root formation is in early stages, surgical repositioning is frequently the treatment of choice. In this article, the case of a horizontally impacted and dilacerated maxillary central incisor is presented which was treated by surgical repositioning. The tooth developed an unusual form of the root with discontinuity at the middle third region with the coronal and apical parts growing separately. Radiographic and clinical monitoring of the case was regularly performed. The tooth completely erupted in 2 years after the repositioning and even after 6 years of surgery is currently successfully functional in the arch with the malformed root. This article highlights the ability of Hertwig's epithelial root sheath to withstand trauma and its ability to recover.

Adenomatoid odontogenic tumor (AOT) is a well-recognised slow growing benign tumor derived from complex system of dental lamina or its remnants. This lesion is categorised into three variants of which the more common variant is follicular type which is often mistaken for dentigerous cyst. We present a case of AOT in a 14-year-old male who was misdiagnosed as dentigerous cyst. Clinical radiological and therapeutic characteristics of the case are commented on in detail.
ABSTRACT
OBJECTIVE: To compare the effectiveness of three different motivational techniques for maintaining good oral hygiene during fixed appliance orthodontic treatment. MATERIALS AND METHODS: A total of 62 adolescents in the age range of 12-18 years, requiring fixed orthodontic treatment were evaluated for the efficacy of three different motivational techniques, ie, conventional plaque control measures (group I), chair side motivational tests with conventional plaque control measures (group II), and phase contrast microscopy with conventional plaque control measures (group III), in improving oral hygiene and gingival health over a period of 6 months. RESULTS: A gradual decline in mean plaque scores in group III was found, ie, from 1.13 ± 0.42 at baseline to 0.64 ± 0.39 at 6 months (P < .05). An intragroup analysis of mean gingivitis scores in group III showed statistically significant decline in the mean gingival scores from 1.49 ± 0.45 to 1.08 ± 0.61 over a period of 6 months(P < .05). CONCLUSIONS: Phase contrast microscopy along with the conventional method of plaque disclosure and demonstration of the horizontal scrubbing method of brushing have a long-lasting effect on the patient. This reduces the need of frequent reinforcement sessions of plaque control programs when compared to chair side motivational tests and conventional plaque control measures.
