Assessment of cheiloscopy in sex determination using lysochrome - A preliminary study.

INTRODUCTION: The present study was undertaken with the objective of ascertaining whether latent lip prints generated by persistent lipsticks and developed using lysochrome dyes have the potential of use in sex determination and personal identification. MATERIALS AND METHODS: This study included a total of 100 subjects (50 males and 50 females) whose latent lip prints were obtained by applying the persistent lipstick Revlon ColorStay Overtime(®) manufactured by Revlon(®) consumer products corporation, NewYork, USA, and lifting the prints with cellophane sheets. The prints were then developed using lysochrome dyes, and all the samples were blinded and then graded based on defined patterns from the Suzuki and Tsuchihashi classification. RESULTS: No two lip prints were found to be alike. Type I was found to be the most prevalent type. In the female population, Type I (61%) was most prevalent, followed by Type I' (28%), Type II (9%), Type III (2%), Type IV (1%), and Type V (1%); in the male population, Type I (33%) was most prevalent, followed by Type II (23%), Type III (18%), Type IV (14%), Type I' (10%), and Type V (3%). Two examiners were able to determine the correct sexes from the given sample sizes. Their interobserver agreement was assessed using the kappa coefficient for males (κ =0.870) and females (κ = 0.870). Their accuracy was assessed with a confidence interval (CI) of 91.48-99.38. CONCLUSION: Lysochrome dyes are very efficacious in developing latent lip prints. This preliminary study has conclusively proved that latent lip prints developed with lysochrome dyes hold the potential for use in sex determination and can be maintained in a digital database.

Hypertrichotic Giant Nevus Spilus Tardivus and Neurofibroma of the Tongue in Sporadic von Recklinghausen's Disease.

Solitary neurofibromas are rare, benign tumours of nonodontogenic origin. The presentation of a solitary neurofibroma on the tongue is an uncommon occurrence and we present such a case here which was discovered in concomitance with multiple neurofibromatosis type 1 (von Recklinghausen's disease). Such a rare presentation seen in this case is a diagnostic challenge and often clinched only with the aid of histopathological and immunohistochemical examination. This work also discusses the various differential diagnoses that can be considered in similar cases. The presence of a hypertrichotic "giant" nevus spilus tardivus (Becker's nevus) is also a rare finding in this particular case. We present such a case which will be of interest to the budding dental practitioner. The lesion was excised and the patient followed up without any evidence of malignant transformation.

A survey on radiographic prescription practices in dental implant assessment among dentists in Kerala, India.

AIMS AND OBJECTIVES: To conduct a survey of the current radiographic prescription practices among implant practitioners in the state of Kerala, India. METHODS: 300 dentists were interviewed by employing a questionnaire which enquired about the radiographic evaluation methods prescribed by practitioners in implant site assessment in their implantology practice. Other reasons for choosing particular imaging modalities were also enquired. The data collected from the survey was analysed using Epi-Info 7.1.3 software. RESULTS: Around 87.33% of the dentists prescribed only OPG for the implant site assessment and only 4.66% ordered Orthopantomograph (OPG) in combination with an Intra Oral Periapical Radiograph (IOPAR) and 4.33% ordered OPG with Computed Tomography (CT). Only 0.02% of the practitioners ordered CT as a single examination and 1% ordered it in conjunction with other modalities. 0.066% individuals ordered IOPAR as the sole imaging modality and none of them ever prescribed conventional or Cone beam computed tomography. CONCLUSIONS: Our study has conclusively proven that most of the dentists prescribe OPG followed by a combination of OPG and Intraoral periapical radiographs in their implant practices. Many of them were not aware and did not follow the American Academy of Oral and Maxillofacial Radiology, European Academy of Dentomaxillofacial Radiology, European Association of Osseointegration and International Congress of Oral Implantology recommendations regarding cross-sectional imaging.

Cysticercosis of the masseter.

Cysticercosis of the oral cavity is a very rare soft tissue lesion and very few cases have been reported worldwide. Here we report a case of a cysticercous cellulosae within the masseter muscle which was diagnosed with the help of high resolution ultrasonography (USG) and ultrasound guided fine needle aspiration cytology (FNAC) and managed conservatively using oral antiparasitic medication. Cysticercosis is not commonly considered in the diagnosis of swellings of the head and neck and this is the reason why they are of utmost interest to the practitioner and have to be studied.
